David Hume

, Philosopher / Historian

  • Born: 26 April 1711
  • Birthplace: Edinburgh, Scotland
  • Died: 25 August 1776
  • Best Known As: Scottish skeptic who wrote A Treatise of Human Nature

David Hume was a prominent figure of the 18th century's Scottish Enlightenment, known especially for his skepticism and rejection of theism. His early philosophical work, A Treatise of Human Nature, first published anonymously around 1739, is considered a standard of Western philosophy. Hume, taking his cue from John Locke, rejected metaphysics in favor of a focus on the empirical method -- the idea that experience and observation should be the foundation of all human knowledge. His dismissal of religion kept him from getting desired academic posts, but Hume became well known for his philosophical works and the controversies they caused, and his multi-volume History of England (1754-62) made him financially secure in his later years. Like his friend Adam Smith, Hume wrote about politics, economics and the moral obligations of government. Some of his most famous works are posthumously published works on religion, including A Natural History of Religion and An Enquiry Concerning the Principles of Morals.

Hume famously helped Jean-Jacques Rousseau out of Switzerland, then set him up at a house in England. Rousseau ended up accusing Hume of being part of a plot against him, and the two had a public falling out, with Hume publishing his defense as A Concise and Genuine Account of the Dispute Between Mr. Hume and Mr. Rousseau: With the Letters that Passed Between Them During Their Controversy (1766).

 
 
Biography: David Hume

The Scottish philosopher David Hume (1711-1776) developed a philosophy of "mitigated skepticism," which remains a viable alternative to the systems of rationalism, empiricism, and idealism.

If one was to judge a philosopher by a gauge of relevance - the quantity of issues and arguments raised by him that remain central to contemporary thought - David Hume would be rated among the most important figures in philosophy. Ironically, his philosophical writings went unnoticed during his lifetime, and the considerable fame he achieved derived from his work as an essayist and historian. Immanuel Kant's acknowledgment that Hume roused him from his "dogmatic slumbers" stimulated interest in Hume's thought.

With respect to Hume's life there is no better source than the succinct autobiography, My Own Life, written 4 months before his death. He was born on April 26, 1711, on the family estate, Ninewells, near Edinburgh. According to Hume, the "ruling passion" of his life was literature, and thus his story contains "little more than the History of my writings." As a second son, he was not entitled to a large inheritance, and he failed in two family-sponsored careers in law and business because of his "unsurmountable aversion to everything but the pursuits of Philosophy and general learning." Until he was past 40, Hume was employed only twice. He spent a year in England as a tutor to a mentally ill nobleman, and from 1745 to 1747 Hume was an officer and aide-de-camp to Gen. James Sinclair and attended him on an expedition to the coast of France and military embassies in Vienna and Turin.

Major Works

During an earlier stay in France (1734-1737) Hume had written his major philosophic work, A Treatise of Human Nature. The first two volumes were published in 1739 and the third appeared in the following year. The critical reception of the work was singularly unfortunate. In Hume's own words, the Treatise "fell dead born from the press." Book I of the Treatise was recast as An Enquiry concerning Human Understanding and published in 1748. The third volume with minor revisions appeared in 1751 as An Enquiry concerning the Principles of Morals. The second volume of the Treatise was republished as Part 2 of Four Dissertations in 1757. Two sections of this work dealing with liberty and necessity had been incorporated in the first Enquiry. Hume's other important work, Dialogues concerningNatural Religion, was substantially complete by the mid-1750s, but because of its controversial nature it was published posthumously.

During his lifetime Hume's reputation derived from the publication of his Political Discourses (1751) and six-volume History of England (1754-1762). When he went to France in 1763 as secretary to the English ambassador, Hume discovered that he was a literary celebrity and a revered figure among the philosophes. He led a very happy and active social life even after his retirement to Edinburgh in 1769. He died there on Aug. 25, 1776. He specified in his will that the gravestone be marked only with his name and dates, "leaving it to Posterity to add the rest."

"Mitigated Skepticism"

Skepticism is concerned with the truthfulness of human perceptions and ideas. On the level of perception, Hume was the first thinker to consistently point out the disastrous implications of the "representative theory of perception," which he had inherited from both his rationalist and empiricist predecessors. According to this view, when I say that I perceive something such as an elephant, what I actually mean is that I have in my mind a mental idea or image or impression. Such a datum is an internal, mental, subjective representation of something that I assume to be an external, physical, objective fact. But there are, at least, two difficulties inherent in ascribing any truth to such perceptions. If truth is understood as the conformity or adequacy between the image and the object, then it is impossible to establish that there is a true world of objects since the only evidence I have of an external world consists of internal images. Further, it is impossible to judge how faithfully mental impressions or ideas represent physical objects.

Hume is aware, however, that this sort of skepticism with regard to the senses does violence to common sense. He suggests that a position of complete skepticism is neither serious nor useful. Academic skepticism (the name derives from a late branch of Plato's school) states that one can never know the truth or falsity of any statement (except, of course, this one). It is, however, a self-refuting theory and is confounded by life itself because "we make inferences on the basis of our impressions whether they be true or false, real or imaginary." Total skepticism is unlivable since "nature is always too strong for principle." Hume therefore advances what he calls "mitigated skepticism." In addition to the exercise of caution in reasoning, this approach attempts to limit philosophical inquiries to topics that are adapted to the capacities of human intelligence. It thus excludes all metaphysical questions concerning the origin of either mind or object as being incapable of demonstration.

Theory of Knowledge

Even though an ultimate explanation of both the subject or object of knowledge is impossible, Hume provides a description of how man senses and understands. He emphasizes the utility of knowledge as opposed to its correctness and suggests that experience begins with feeling rather than thought. He uses the term "perception" in its traditional sense - that is, whatever can be present to the mind from the senses, passions, thought, or reflection. Nonetheless he distinguishes between impressions which are felt and ideas which are thought. In this he stresses the difference between feeling a toothache and thinking about such a pain, which had been obscured by both rationalists and empiricists. Both impressions and ideas are subdivided further into simple and complex; for example, the idea of heat is simple, while the idea of combustion is complex.

These simple divisions are the basis for Hume's "phenomenalism" (that is, knowledge consists of "appearances" in the mind). Hume distinguishes the various operations of the mind in a descriptive psychology, or "mental geography." Impressions are described as vivacious and lively, whereas ideas are less vivid and, in fact, derived from original impressions. This thesis leads to the conclusion that "we can never think of any thing which we have not seen without us or felt in our own minds." Hume often overestimates the importance of this discovery with the suggestion that the sole criterion for judging ideas is to remove every philosophical ambiguity by asking "from what impression is that supposed idea derived." If there is no corresponding impression, the idea may be dismissed as meaningless. This assumption that all ideas are reducible, in principle, to some impression is a primary commitment of Hume's empiricism. Hume did admit that there are complex ideas, such as the idea of a city, that are not traceable to any single impression. These complex ideas are produced by the freedom of the imagination to transform and relate ideas independently of impressions; such ideas are not susceptible to empirical verification. This represents the major paradox of Hume's philosophy - the imagination which produces every idea beyond sensible immediacy also denies the truth of ideas.

Theory of Ideas

Hume accepts the Cartesian doctrine of the distinct idea - conceivability subject only to the principle of contradiction - as both the unit of reasoning and the criterion of truth. But the doctrine of the distinct idea means that every noncontradictory idea expresses an a priori logical possibility. And the speculative freedom of the imagination to conceive opposites without contradiction makes it impossible to demonstrate any matter of fact or existence. This argument leads to a distinction between relations of ideas (demonstrations which are true a priori) and matters of fact (the opposite of which is distinctly conceivable). And this distinction excludes from the domain of rational determination every factual event, future contingent proposition, and causal relation. For Hume, since truth is posterior to fact, the ideas of reason only express what the mind thinks about reality.

Distinct ideas, or imaginative concepts, are pure antinomies apart from experience as every factual proposition is equally valid a priori. But Hume does acknowledge that such propositions are not equally meaningful either to thought or action. On the level of ideas, Hume offers a conceptual correlative to the exemption of sensation as a form of cognition by his recognition that the meaning of ideas is more important than their truth. What separates meaningful propositions from mere concepts is the subjective impression of belief.

Belief, or the vivacity with which the mind conceives certain ideas and associations, results from the reciprocal relationship between experience and imagination. The cumulative experience of the past and present - for example, the relational factors of constancy, conjunction, and resemblance - gives a bias to the imagination. But it is man's imaginative anticipations of the future that give meaning to his experience. Neither the relational elements of experience nor the propensive function of the imagination, from the viewpoint of the criterion of truth, possesses the slightest rational justification. Hence the interplay between the criterion of truth and the logic of the imagination explains both Hume's skepticism and his conception of sensation and intellection.

The most celebrated example of this argument is Hume's analysis of the causal relation. Every statement which points beyond what is immediately available to the senses and memory rests on an assumption and/or extension of the cause and effect relation. Let us examine two cases: I see lightning and hear thunder; I see a rabbit and then a fox. The question is why I am right in concluding that lightning causes thunder but wrong in believing that rabbits cause foxes. Experience, in both instances, reveals an A that is followed by B, and repeated experiences show that A is always followed by B. While the constant conjunction of A and B might eliminate the rabbit-fox hypothesis, it is of no help in explaining causality because there are all sorts of objects, such as tables and chairs, which are similarly conjoined but not supposed to be causally related. Thus experience reveals only that constant conjunction and priority are sufficient but not necessary conditions for establishing a causal connection. And it is necessity, understood as that which cannot be otherwise than it is, which makes a relation causal in the propositional form of "If A then B must appear and if no A then no B."

But if necessary connection explains causality, what explains necessity? Experience yields only a particular instance and tells us nothing about the past or the future. Nor is there any necessity discoverable in repeated experiences. That the sun will rise tomorrow because it has in the past is an assumption that the past necessarily causes the future which is, of course, the connection that is to be demonstrated. If experience cannot account for necessity, then reason fares no better. I can always imagine the opposite of any matter of fact without contradiction. If someone tells me that Caesar died of old age or that thunder is uncaused or that the sun will not rise tomorrow, I will not believe him, but there is nothing logically incorrect about such statements since for every probability "there exists an equal and opposite possibility." Thus there is no justifiable knowledge of causal connections in nature, although this is not a denial that there are real causes. Man's supposed knowledge results from repeated associations of A and B to the point where the imagination makes its customary transition from one object to its usual attendant, that is, "an object followed by another, and whose appearance always conveys the thought to that other."

Because of his skeptical attitude toward the truths of reason Hume attempted to ground his moral theory on the bedrock of feeling - "Reason is, and ought only to be, the slave of the passions." In this, Hume followed the "moral sense" school and, especially, the thought of Francis Hutcheson. The notion that virtue and vice are to be derived ultimately from impressions of approbation and blame or pleasure and pain shows that Hume anticipated Jeremy Bentham's utilitarianism, a debt which the latter acknowledged. Although Hume considered himself to be primarily a moralist, this doctrine is the least original part of his philosophical writings.

(1711-76) Scottish empiricist philosopher and historian, who, born in Edinburgh and remaining unmarried, held several posts in his life, but never achieved high office in the academic world or elsewhere. He did, though, achieve the ‘literary fame’ which was his sole expressed ambition: his work was widely admired and discussed in Scotland, France, England, and beyond, and his reputation, though viciously attacked by eminent Victorians such as Carlyle, has been maintained on a high level ever since.

This reputation is not primarily as a political theorist, but in the fields of epistemology and ethics, where his Enquiry concerning Human Understanding and A Treatise of Human Nature respectively have given him an undisputed eminent place in the history of philosophy. His position in the history of political thought is not generally considered to be so large. There is no work comparable to Hobbes's Leviathan, Rousseau's Social Contract, or even Locke's Two Treatises on Civil Government; it is a consequence of his approach to politics that there could not be. Hume's conventionally ‘political’ works consist of something between a dozen and two dozen essays, depending on what one means by politics. Yet Hume is, in many respects, a deeply political writer. His epistemology cannot be ignored by anyone seeking to explain politics, his consideration of the nature of morality, including convention, justice, and property, is an important political theory in all but conventional categorization and these are complemented by his overtly political essays and his History of England in six volumes.

Hume wrote forcefully, in elegant, common language: no British philosopher is further removed than Hume from the Germanic habit of inventing terms and creating concepts. Yet Hume's clarity is often said to be deceptively, even deceitfully, misleading: the contradictions and ambiguities of Hume's writings as a whole are legion and he can make an apparently simple concept, like ‘the association of ideas’, which he is often accused of overusing, into a puzzle as unclear as anything in Kant or Hegel. Take, for example, four famous Humean arguments:

(1) Hume's fork’: the insistence, most clearly in the Enquiry, that true statements come in two forms, ‘relations of ideas’ (especially mathematics) and ‘matters of fact’. Books full of claims which fall into neither category should be ‘consigned to the flames’. This argument suggests Hume as an intellectual ancestor of the logical positivists.
(2) Atheism: the Dialogues concerning Natural Religion, consistently with much of Hume's epistemological writings, appear to favour rejection of all the established arguments in favour of religion including the ontological argument, the necessity of a Creator, and so on.
(3) Causation: Hume argued that causes did not have a separate existence, that the idea of causation must be reduced to the ‘constant conjunction’ of what we imagine to be causes and their effects.
(4) The gap between facts and values: or, in Hume's terms, the impossibility of inferring an ‘ought’ from an ‘is’.

 Yet all of these arguments, put so forcefully by Hume in famous passages, are contradicted or mitigated elsewhere in his writings and have been interpreted in widely different ways. The ‘relations of ideas’ category is expanded far beyond the bounds allowed by the logical positivists and Hume insists on the untenability of complete scepticism. Not only is there private correspondence which seems to establish Hume as a religious believer, but the Dialogues contain convincing arguments in favour of an anthropomorphic analogy for any principle of order in the universe and for the necessity of religion reinforcing morality.

The argument from ‘constant conjunction’ can be cited as both a scepticism about science and as a redefining basic principle for Newtonian physics and thus modern science. Some critics have argued that Hume, far from instigating a rigid distinction between fact and value, collapsed such a distinction and convincingly portrayed certain kinds of morality as natural and compelling because of their naturalness.

Similar contradictions threaten the clarity of his political writings. In his essay, ‘Of the Original Contract’, he sustains, with great force and elegance, a contempt for the plausibility and usefulness of any idea of government being based on the kind of contract posited by Hobbes, Locke, or Rousseau. Government is founded on ‘usurpation or conquest’; it must be supported because of its beneficial consequences and it would not last five minutes if subjected to the test of having to fulfil a valid contract. But in many other passages, including the essay Of the Origin of Government, he seems much more sympathetic to a contractual account. In That Politics may be reduced to a Science he argues against the possibility of general prescriptions of how government should be organized while in Idea of a Perfect Commonwealth he appears to offer us just such a general prescription, a devolved, elected, republic, based on a property franchise with a separation of powers.

The accusation must be considered that Hume was inconsistent and negative. Contesting such considerations must start with Hume's beliefs and prejudices about English history. His History ends with the ‘Glorious Revolution’ of 1689: ‘we, in this island, have ever since enjoyed if not the best system of government, at least the most entire system of liberty, that ever was known among mankind.’ Nothing could be stronger or more consistent in Hume's view of the world than the contrast between his abhorrence for the doctrinaire, vicious milieu of the seventeenth century, with its religious persecutions, civil wars, and political crises, and his gratitude for finding himself alive in the eighteenth century. His own age, as he portrayed it in his essays on economics and the arts, was an unprecedented period of peace, stability, prosperity, and freedom of expression. His disgust at the excesses of the seventeenth century is well shown in his version of the Popish Plot period of 1678-9 with its show trials (as we should now call them) and its hypocrisies, in which both sides, supporters of Parliament and monarch, were equally objectionable in his view.

How did the happy condition of the eighteenth century arise? On what principle was it based? How was it to be maintained? These were essential questions for Hume and he had subtle and important answers to them. The settlement of British political problems had not come about because the right side won, still less because the correct doctrine prevailed. Of William of Orange, the principal beneficiary of the Glorious Revolution, he says, ‘though his virtue, it is confessed, be not the purest, which we meet with in history, it will be difficult to find any person, whose actions and conduct have contributed more eminently to the general interests of society and of mankind’. Thus he supports the same side as John Locke, but regards Locke as taking the right side, not just for the wrong reason, but for the wrong sort of reason. Acceptance of the Glorious Revolution and the subsequent Hanoverian Settlement starts with its good effects. One reason these effects are good is that they give a preponderant victory to the Whigs, but not a total victory: the monarchy remains, with Hume's support, allowing a government which is ‘mixed’ in its principles and institutions and therefore moderate in its nature. Above all, political life is no longer a contest over abstract or religious truth; Hume had as much contempt for divine right as for contract theory, and as much again for the popular political dogmas they generated: the Tory doctrine of passive obedience and Whig doctrine of the right of resistance. Whatever the subtleties of Hume's religious position, he was consistently opposed to religion in its seventeenth-century form, which claimed philosophical truth and moral substance. By contrast, he saw ‘ancient religion’ as a benign package of myths, morals, and allegiances which required no dogma.

Hume's philosophical arguments and historical judgements can be synthesized as follows: the purpose of government is the well-being of the people, but you cannot bring government into being or destroy governments in relation to that purpose, because to do so would not be beneficial. Governments arise by contingency; they are worthy of obedience not because of any rigorous principle, but because their maintenance allows the freedom and stability which is conducive to the general well-being. Human institutions are founded not on abstract principles, but on conventions; justice and property are necessary conventions in conditions of scarcity. Some conventions have a natural basis, not in that they can be derived naturally from reason, but in the sense that they flow from the sympathy which exists naturally in all of us and links us together. The question for political theorists is not, ‘In what circumstances can we justify acceptance of and obedience to government?’, but ‘How can we understand the nature of the bonds which form a society and give us the habit of being governed without resorting to the kind of theological and moral dogmas which are intellectually unacceptable and practically dangerous?’ Most elements of this body of theory are shared with Hume's contemporaries: the relativism and passion for moderate government is shared with Montesquieu; the ultimately sensual purpose is shared with the utilitarians, though without a linear concept of well-being or the apparent rigour of Bentham; the belief in a society based on convention, which grows in conditions of stability, is shared with Burke. Yet the whole constitutes one of the most subtle and important of modern political philosophies.

(born May 7, 1711, Edinburgh, Scot. — died Aug. 25, 1776, Edinburgh) Scottish philosopher, historian, and economist. He conceived of philosophy as the inductive, experimental science of human nature. His first major work, A Treatise of Human Nature (1739 – 40), explains the origin of ideas, including the ideas of space, time, and causality, in sense experience; presents an elaborate account of the affective, or emotional, aspects of the mind and assigns a subordinate role to reason in this order ("Reason is, and ought only to be, the slave of the passions"); and describes moral goodness in terms of "feelings" of approval or disapproval that a person has when he considers human behaviour in the light of the agreeable or disagreeable consequences either to himself or to others. The Treatise was poorly received, and late in life Hume repudiated it as juvenile. He revised Book I of the Treatise as An Enquiry Concerning Human Understanding (1758); a revision of Book III was published as An Enquiry Concerning the Principles of Morals (1751). His Dialogues Concerning Natural Religion (1779), containing a refutation of the argument from design and a critique of the notion of miracles, was withheld from publication during his lifetime at the urging of friends. From his account of the origin of ideas Hume concluded that we have no knowledge of a "self" as the enduring subject of experience; nor do we have knowledge of any "necessary connection" between causally related events. Immanuel Kant, who developed his critical philosophy in direct reaction to Hume, said that Hume had awakened him from his "dogmatic slumbers." In Britain, Hume's moral theory influenced Jeremy Bentham to adopt utilitarianism. With John Locke and George Berkeley, Hume is regarded as one of the great philosophers of empiricism.

British History: David Hume

Hume, David (1711-76). Philosopher and historian, the younger son of a strict presbyterian laird, Hume lost his Christian belief at Edinburgh University in the 1720s. His Treatise of Human Nature (1739-40) provided a devastating critique of contemporary metaphysics, which cleared the ground for a genuinely empirical account of human understanding. His massive History of England (1754-63) is a neglected masterpiece, which remained a best seller for more than a century. In general Hume wanted to reconstruct the political culture of his age and to recommend a ‘sceptical Whiggery’ to his contemporaries as an antidote to party zealotry and an ally of commerce.

 

Hume, David (1711-76) Scottish philosopher, historian, and essayist. Hume is the most influential thoroughgoing naturalist in modern philosophy, and a pivotal figure of the Enlightenment. Born the second son of a minor Scottish landowner, Hume attended Edinburgh university. In 1734 he removed to the little town of La Flèche in Anjou to write and study (it is possible that the presence of the Jesuit College at which Descartes and Mersenne had been educated, influenced this decision). In 1739 he returned to oversee the printing of the Treatise of Human Nature, his first and greatest philosophical work. Hume settled down to a life of literary work, mainly residing in Edinburgh, although he was a rather improbable aide to General James St Clair, a distant relation, for a time between 1746 and 1748. Earlier he had produced the Essays Moral and Political (1742). These range from light-hearted exercises in the manner of Joseph Addison to weighty and important treatments of the foundations of ethics, politics, and economics. They were followed by An Enquiry Concerning Human Understanding (1748) and An Enquiry Concerning the Principles of Morals (1751). These works are usually regarded as attempts to lay out the philosophy of the Treatise in a more accessible manner, although particularly the second Enquiry contains distinct differences at least of emphasis. In the following decade Hume began publication of the work by which he was best known in his own time, the History of England (in six volumes, 1754-62; the work was subsequently extended by Smollett). During this period his reputation slowly grew until he became acknowledged as one of Britain's principal men of letters. In 1763 he was appointed Secretary to the Embassy and later chargé d'affaires in Paris, and during this period enjoyed unprecedented fame and adulation as one of the principal architects of the Enlightenment. He failed, however, to win the hand of the mistress of Louis-François de Bourbon, Prince de Conti, the Comtesse de Boufflers, to whom he formed a deep romantic attachment. Perhaps this was because at this time he began to resemble, in Diderot's words, ‘un gros Bernardin bien nourri’ (a fat well-fed Bernardine monk). In 1766 Hume accompanied Rousseau to England, but the trip ended with paranoid complaints of persecution by Rousseau, against which Hume defended himself with dignity. Out of his ‘abundant caution’ he delayed the publication of his last sceptical philosophical work, The Dialogues Concerning Natural Religion, until after his death, when they were published by his nephew. Adam Smith wrote of Hume that ‘upon the whole, I have always considered him, both in his life-time and since his death, as approaching as nearly to the idea of a perfectly wise and virtuous man, as perhaps the nature of human frailty will admit.’

The avowed aim of the Treatise was to bring the experimental method into the study of the human mind. Hume believed that the success of natural science, culminating in Newtonian mechanics, lay in finding the few simple principles that would enable one to discern order in the apparent chaos of natural systems. Events in nature are in themselves ‘loose and separate’, and the art of the scientist is to detect the patterns in which they fall. Similarly separate events in the mind, such as the onset of ideas, impressions, and passions, should be seen as natural events, ordered by principles that are open to empirical discovery. The first components of the mind are individual ‘perceptions’ or impressions and ideas. Ideas for Hume, as for earlier empiricists such as Berkeley, are faint or less forceful versions of impressions. They are the components of thought, and Hume was the first modern philosopher seriously to explore the difficulty of explaining how, on the basis of this private kaleidoscope, we attain a conception of ourselves as inhabiting a public world of independent objects extended in space and ordered by causal laws. Hume's resolute naturalism rejects any model in which sense experience enables us to reason our way to such a conception; instead it arises purely as the result of ‘custom and habit’, and reason can neither assist nor oppose the process. Similarly the passions, under which Hume includes any pressure on practical choice, including ethical pressure, are outside the sway of reason but themselves rise and fall in naturally detectable patterns.

Hume was the first modern empiricist to refuse any aid either from a priori principles of reasoning, or from any other ideology that ensures a harmony between our perceptions and the world. His genius lay in the rigour with which he reconstructs the scaffolding of everyday thought on this slender basis. Thus the causal connection between events is something of which we have no impression, hence no idea, so a Humean theory of causation instead sees us as projecting onto events our own tendency to infer one from another (see projectivism). The mind that is the owner of my perceptions is something that itself is never given to me in perception, so a Humean theory of the self regards it as a fiction arising from imagination (see bundle theory of the mind or self, personal identity). A Humean theory of ethics sees moral thought as the expression of sentiments that evolve because we must cooperate in societies if we are to meet our natural needs. Although Hume is often called a sceptic in these and other areas, it is only the power of reason about which he is sceptical, not the propriety of natural processes of belief-formation, against which, in any event, it is futile to argue.

In the Enquiries, Hume downplays the original foundations of his philosophy, in favour of a more accessible presentation of the way he would have us think about theoretical belief-formation, and practical reasoning. His scepticism about reason did not leave him lacking any distinction between proper and improper processes of arriving at belief, although his right to such a distinction has been challenged. In section x, on Miracles, in the first Enquiry, he gleefully shows that it makes no sense to credit human reports of miracles: the falsity of such a testimony through ‘folly or knavery’ would be a natural event, less miraculous and more probable than that which it relates. His sceptical attitude both to revealed and natural theology culminated in the sustained attack on the argument to design in the posthumous Dialogues.

Hume's Olympian intelligence earned him incalculable influence: almost all anthropological, sociological and comparative studies find a seed in his work, whilst the attempt to escape his radical empiricism has motivated philosophers from Kant to the present day. The standard modern biography was by Ernest Mossner.

 
(hyūm) , 1711–76, Scottish philosopher and historian. Educated at Edinburgh, he lived (1734–37) in France, where he finished his first philosophical work, A Treatise of Human Nature (1739–40). His other philosophical works include An Enquiry Concerning Human Understanding (1748; a simplified version of the first book of the Treatise), An Enquiry Concerning the Principles of Morals (1751), Political Discourses (1752), The Natural History of Religion (1755), and Dialogues Concerning Natural Religion (1779). Hume also wrote an exhaustive History of England (1754–62), whose purity of style overcame the frequent faultiness of fact and made the work the standard history of England for many years. In 1763, Hume returned to Paris as secretary to the British embassy. It was at that time that he became a friend of Jean Jacques Rousseau, to whom he later gave refuge in England. In philosophy Hume pressed the analysis of John Locke and George Berkeley to the logical extreme of skepticism for which he is famous. He could see no more reason for hypothesizing a substantial soul or mind than for accepting a substantial material world. A complete nominalist in his handling of ideas of material objects, he carried the method into the discussion of mind and found nothing there but a bundle of perceptions. Causal relation derives solely from the customary conjunction of two impressions; the apparent sequence of events in the external world is in fact the sequence of perceptions in the mind. From this statement Hume argued that our expectation that the future will be like the past (e.g., that the sun will rise tomorrow morning) has no basis in reason; it is purely a matter of belief. However, he also asserted that such theoretical skepticism is irrelevant to the practical concerns of daily life. Hume's attack on rationalism is also evident in his two works on religion; in these he rejects any rational or natural theology.

History 1450-1789: David Hume

Hume, David (1711–1776), Scottish philosopher and historian. Hume was born in the Scottish border country near Edinburgh into an old family of prosperous provincial lawyers. His father died when he was an infant. His mother never re-married and devoted herself to raising Hume and his brother and sister. Throughout his life Hume was deeply attached to his family and proud of its traditions. He studied at the University of Edinburgh until the age of fourteen or fifteen. For the next ten years he pursued a rigorous plan of independent study that surveyed the whole of humanistic learning and cost him a temporary nervous breakdown. From this period, Hume conceived two projects, the later fulfillment of which would complete his career as a writer—a philosophical science of human nature (comprehending all the sciences) and the writing of history. Hume is unique in being both a great philosopher and a great historian. He is commonly ranked, along with William Robertson, Edward Gibbon, and Voltaire as one of the four most important eighteenth-century historians.

By the age of twenty-six Hume had composed his philosophical masterpiece, A Treatise of Human Nature (1739–1740). The work was not well received, and Hume quickly began recasting its ideas into the more readable form of essays. Most of these were published from 1741 to 1752 and were warmly received in Britain and America and translated into French, German, and Italian. The most important works from this period are Essays: Moral, Political, and Literary (1752), An Enquiry Concerning Human Understanding (1748), and An Enquiry Concerning the Principles of Morals (1751). These essays contain important contributions to epistemology, aesthetics, economics, and moral and political philosophy. The Natural History of Religion (1757) and Dialogues Concerning Natural Religion (published posthumously in 1779), arguably establish Hume as the founder of the philosophy of religion.

Around 1752 he turned to the second project set for himself in his youth, namely the writing of history. The History of England appeared in six volumes over the years 1754–1762. It achieved the status of a classic in Hume's lifetime, was viewed as the standard work on the subject for nearly a century, and was in print down to the end of the nineteenth century, passing through at least 160 posthumous editions. Hume had now achieved a European reputation as one of the great writers of his age, and he enjoyed friendships with such illustrious figures as Adam Smith, Jean-Jacques Rousseau, Anne Robert Jacques Turgot, Denis Diderot, Jean d'Alembert, and Benjamin Franklin.

In 1983 The History of England was republished after having been out of print for nearly a century. During that period Hume had been narrowly thought of as a technical philosopher. The early skeptical and negative interpretation of The Treatise of Human Nature put forth by James Beattie, Thomas Reid, Immanuel Kant, and John Stuart Mill persisted far into the twentieth century. Hume's historical work was considered irrelevant to his philosophy and almost entirely forgotten. Hume, however, thought of the History as an integral part of his philosophical work. This can best be appreciated by considering his skepticism. The ancient Pyrrhonians taught that the main source of misery for highly cultivated people is the attempt to guide life by philosophical speculation. Hume denied that the disposition to philosophize could or should be purged, but he agreed with the Pyrrhonians that philosophical speculation can be a source of disorder in the soul. The first problem for Hume's science of human nature, then, was to distinguish what he called "true philosophy" from its corrupt and corrupting forms. Hume used skeptical tropes to make this distinction. His intention was neither to subvert (Beattie, Reid, Mill) nor to raise skeptical challenges for others to solve (Kant). His goal was to purge the philosophical intellect of its corrupt forms.

False philosophy seeks radical autonomy and imagines itself emancipated from the pre-reflective customs and prejudices of common life. True philosophy knows this to be a psychological and conceptual impossibility. True philosophy may still speculate about reality but only by critically passing through, and rendering more coherent, the inherited prejudices of common life. Hume went beyond the Pyrrhonians in teaching that false philosophy has a corrupting effect not only on the soul but on social and political order as well—and especially so under modern conditions where, for the first time in history, the disposition to philosophize was becoming a mass phenomenon. He narrated the tragedy of the English Civil War in the History as just such a corruption. His critique of philosophical rationalism in all its forms (in science, morals, politics, religion, and philosophy itself) is the one theme that unites his philosophical and historical work. And it establishes Hume as the first to work out a systematic critique of modern ideologies.

David Hume (April 26, 1711August 25, 1776)[1] was a Scottish philosopher, economist, and historian. He is considered one of the most important figures in the history of Western philosophy and the Scottish Enlightenment. Although in recent years interest in Hume's work has centred on his philosophical writing, it was as an historian that he first gained recognition and respect. His The History of England[2] was the standard work on English history for sixty or seventy years until Macaulay's.[3]

Hume was the first great philosopher of the modern era to carve out a thoroughly naturalistic philosophy. This philosophy partly consisted in the rejection of the historically prevalent conception of human minds as being miniature versions of the Divine mind; a notion Edward Craig has entitled the ‘Image of God’ doctrine.[4] This doctrine was associated with a trust in the powers of human reason and insight into reality, which powers possessed God’s certification. Hume’s scepticism came in his rejection of this ‘insight ideal’,[5] and the (usually rationalistic) confidence derived from it that the world is as we represent it. Instead, the best we can do is to apply the best explanatory and empirical principles available to the investigation of human mental phenomena, issuing in a quasi-Newtonian project, Hume's ‘Science of Man’.

Hume was heavily influenced by empiricists John Locke and George Berkeley, along with various Francophone writers such as Pierre Bayle, and various figures on the Anglophone intellectual landscape such as Isaac Newton, Samuel Clarke, Francis Hutcheson, Adam Smith, and Joseph Butler.[6]

Life

David Home (later Hume) was the son of Joseph Home of grindsted, advocate, and Katherine, Lady Falconer, was born on 26 April 1711 (Old style) in a tenement on the North side of the Lawnmarket in Edinburgh. Throughout his life Hume, who never married, was to spend time occasionally at his family home at Ninewells by Chirnside, Berwickshire. (He changed his name to Hume in 1734 because the English had difficulty in pronouncing Home in the Scottish manner.) He was sent by his family to the University of Edinburgh at the unusually early age of twelve, perhaps as young as ten (fourteen would have been more normal). At first he considered a career in law, but came to have, in his words, "an insurmountable aversion to everything but the pursuits of Philosophy and general Learning; and while [my family] fanceyed I was poring over Voet and Vinnius, Cicero and Vergil were the Authors which I was secretly devouring." He had little respect for professors, telling a friend in 1735 "there is nothing to be learned from a Professor, which is not to be met with in Books."[7] At the age of eighteen Hume made a philosophical discovery that opened up to him "a new Scene of Thought" which inspired him "to throw up every other Pleasure or Business to apply entirely to it".[8] He did not recount what this was, but it seems likely to have been his theory of causality — that our beliefs about cause and effect depend on sentiment, custom and habit, and not upon reason, nor upon abstract, timeless, general Laws of Nature.

The careers open to a poor Scottish gentleman in those days were very few. As Hume's options lay between a travelling tutorship and a stool in a merchant's office, he chose the latter. In 1734, after a few months in commerce in Bristol, he went to La Flèche in Anjou, France. He had frequent discourses with the Jesuits of the famous college in which Descartes was educated. During his four years there, he laid out his life plan, resolving "to make a very rigid frugality supply my deficiency of fortune, to maintain unimpaired my independency, and to regard every object as contemptible except the improvements of my talents in literature."[9] While there, he completed A Treatise of Human Nature at the age of twenty-six. Although many scholars today consider the Treatise to be Hume's most important work and one of the most important books in the history of philosophy, the public in Great Britain did not agree at first. Hume himself described the (lack of) public reaction to the publication of the Treatise in 1739–40 by writing that it "fell dead-born from the press, without reaching such distinction as even to excite a murmur among the zealots. But being naturally of a cheerful and sanguine temper, I soon recovered from the blow and prosecuted with great ardour my studies in the country". There he wrote the Abstract.[10] Without revealing his authorship, he aimed to make his larger work more intelligible by shortening it. Even this advertisement failed to enliven interest in the Treatise.[11]

The effort of writing the Treatise drove the youthful Hume to near insanity. To restore his perspective he escaped to the common life.[12]

After the publication of Essays Moral and Political in 1744, he applied for the Chair of Pneumatics and Moral Philosophy at the University of Edinburgh. However, the position was given to William Cleghorn, after the majority of Edinburgh ministers petitioned the town council not to appoint Hume because of his atheism.[13] During the Jacobite Rebellion of 1745 he tutored the Marquise of Annandale (1720-92) officially described as a "lunatic".[14] This engagement ended in disarray after about a year. But, it was then that he started his great historical work The History of Great Britain[15] which would take fifteen years and run to over a million words, to be published in six volumes in the period 1754 to 1762. During this period he was involved with the Canongate Theatre and in this context associated with Lord Monboddo and other Scottish Enlightenment luminaries in Edinburgh. In 1748 he served for three years as Secretary to General St Clair writing his Philosophical Essays concerning Human Understanding later published as An Enquiry concerning Human Understanding. The Enquiry proved little more successful than the Treatise.

Hume was charged with heresy, but he was defended by his young clerical friends who argued that as an atheist he lay outside the jurisdiction of the Church. Despite his acquittal—and, possibly, due to the opposition of Thomas Reid of Aberdeen, who that year launched a Christian critique of his metaphysics—Hume failed to gain the Chair of Philosophy at Glasgow. It was after returning to Edinburgh in 1752, as he wrote in My Own Life, that "the Faculty of Advocates chose me their Librarian, an office from which I received little or no emolument, but which gave me the command of a large library." It was this resource that enabled him to continue his historical research for his History.

Hume achieved great literary fame as a historian. His enormous History of Great Britain from the Saxon kingdoms to the Glorious Revolution was a best-seller in its day. In it, Hume presented political man as a creature of habit, with a disposition to submit quietly to established government unless confronted by uncertain circumstances. In his view, only religious difference could deflect men from their everyday lives to think about political matters.

Hume's early essay Of Superstition and Religion laid the foundations for nearly all subsequent secular thinking about the history of religion. Critics of religion during Hume's time were required to express themselves cautiously. Less than 15 years before Hume was born, 18-year-old college student Thomas Aikenhead was put on trial for saying openly that he thought Christianity was nonsense; he was later convicted and hanged for blasphemy. Hume followed the common practice of expressing his views obliquely, through characters in dialogues. Hume did not acknowledge authorship of Treatise until the year of his death, in 1776. His essays On Suicide, and On the Immortality of the Soul and his Dialogues concerning Natural Religion were held from publication until after his death (published 1778 and 1779, respectively), and they still bore neither author's nor publisher's name. So masterly was Hume in disguising his own views that debate continues to this day over whether Hume was actually a deist or an atheist. Regardless, in his own time Hume's alleged atheism caused him to be passed over for many positions.

Hume told his friend Mure of Caldwell of an incident which occasioned his "conversion" to Christianity. Passing across the recently drained Nor’ Loch to the New Town of Edinburgh to supervise the masons building his new house, soon to become No 1 St David Street, he slipped and fell into the mire. Hume, being then of great bulk, could not regain his feet. Some passing Newhaven fishwives seeing his plight, but recognising him as the well-known atheist, refused to rescue him until he became a Christian and had recited The Lord’s Prayer and the Creed. This he did and was rewarded by being set again on his feet by these brawny women. Hume asserted thereafter that Edinburgh fishwives were the "most acute theologians he had ever met".[16]

From 1763 to 1765 Hume was Secretary to Lord Hertford in Paris, where he was admired by Voltaire and lionised by the ladies in society. He made friends with and, later, fell out with Rousseau. He wrote of his Paris life "I really wish often for the plain roughness of the The Poker Club of Edinburgh . . . to correct and qualify so much luciousness." For a year from 1767, Hume held the appointment of Under Secretary of State for the Northern Department. In 1768 he settled in Edinburgh. Attention to Hume's philosophical works grew after the German philosopher Immanuel Kant credited Hume with awakening him from "dogmatic slumbers" (circa 1770) and from then onwards he gained the recognition that he had craved all his life.

James Boswell visited Hume a few weeks before his death. Hume told him that he sincerely believed it a "most unreasonable fancy" that there might be life after death.[17] This meeting was also dramatized in semi-fictional form for the BBC by Michael Ignatieff as Dialogue in the Dark. Hume wrote his own epitaph:"Born 1711, Died [----]. Leaving it to posterity to add the rest." It is engraved with the year of his death 1776 on the "simple Roman tomb" which he prescribed, and which stands, as he wished it, on the Eastern slope of the Calton Hill overlooking his home in the New Town of Edinburgh at No. 1 St David Street.

Hume’s Science of Man

There are, of course, various ways of interpreting Hume’s philosophical project regarding the understanding. Hume certainly adopts the idiom of previous empiricist philosophers such as John Locke in talking of the ideas of the mind, and indeed at least formally accepts the theory that our concepts or ideas are derived from or copied off of our sensory impressions. Some positivist philosophers have thus assumed that his project could be interpreted as a detailed analysis of our concepts in terms of actual or potential experiences. Such interpreters have sought to disentangle the analytical Hume from Hume the psychologist, who saw mental states as linked to one another by laws of association. However, such an interpretation seems doomed to failure, as it has radically anti-sceptical, and thus un-Humean, conclusions. For if our ideas are analysable into experience, then anything we can grasp in the understanding would have first to be knowable by, or directly accessible in, experience. Hume would not have thought of our ideas as thus given in experience; for him, the natural, and importantly non-rational, mechanisms of the mind must go to work on the sensory data or input to produce our concepts.

However, another strain of interpretation that has become prominent in the last couple of decades is that, rather than analysing our ideas into copies of experiences, Hume was instead looking at the way our mind synthesises, or actively generates, our complex notions of and beliefs in, e.g., the external world, causal connection, the self, and so on. For Hume, our forming and using such concepts was the result of an in-built, natural disposition to deploy faculties of the mind such as custom, habit, and the imagination. Another way of expressing this is to say that he was not concerned with advancing a theory of semantics — i.e. what we mean when we talk about, say, physical objects or causal relations — but rather was carrying out an epistemological enquiry, asking in effect how the stimuli of the senses and our conceptual apparatus work together to compel us to form various sorts of judgements and to make claims to knowledge.

The Idea of Necessary Connection

Hume begins Chapter VII of the first Enquiry with a hunt for the impression behind our idea of causal power. This has been interpreted as an attempt to specify the parameters of the concept of causation — i.e. what we mean when we deploy causal terms — and the traditional analytical take on Hume’s answer is that it is to be found in the regular succession of certain of our impressions; their ‘constant conjunction’. On this interpretation, Hume is basically saying that when we make statements of the form "X caused Y", or "Y happened because of X", we just mean that X happened, then Y did, and that X-like events always precede Y-like ones.

However, this take is almost certainly flawed, for at least two reasons. Firstly, Hume offers two ‘definitions’ of causation, the first of which is in terms of pure regularity, but the second of which introduces the notion of the natural passage of the mind from the appearance of the cause to the idea of the effect (e.g. someone knocks a coffee mug off the table and, having always experienced unsuspended objects to fall, you anticipate its falling to the floor). This feeling stems from a natural association of the two events after persistent observation of them as constantly conjoined. And it is this feeling, or ‘determination of the mind’, which is the basis of our idea of necessity, i.e. that the cause necessitates its effect.

Secondly, this is the basis for our idea not in the sense that our concept of necessary connection can be analysed into such feelings of anticipation, expectation, etc., but that we then come to see the world as structured by a certain predictability of order, and we attribute this predictability to the external objects themselves, i.e. we attribute them a causal power which makes things fall out, or occur in, the way they do; a property of necessary connection. So Hume's argument is that the mind synthesises and then projects a concept of causal power when it observes similar events to occur together repeatedly. This is an example of what the philosopher Simon Blackburn has entitled ‘projectivism’; Hume argues that we project our feeling of predictability onto the objects, much as he argues that we project our moral attitudes onto situations or objects, as “nothing is more usual than to apply to external bodies every internal sensation which they occasion.”[18]

The Problem of Induction

Main article: Problem of induction

In his Enquiry Concerning Human Understanding, §4.1.20-27, §4.2.28-33,[19] Hume articulated his view that all human reasoning is of two kinds, to wit Relation of Ideas and Matters of Fact. While the former involves the abstract concepts of logic and mathematics where intuitive and deductive certitude presides, the latter concerns what exists in the world. In order to avail ourselves of any matter of fact or existence beyond what we are aware of in our present sensory experience and our memory, we must employ inductive reasoning.

Inductive inference operates on the principle that the past acts as a reliable guide to the future (sometimes called the principle of the uniformity of nature). For example, if in the past the sun has risen in the east and set in the west, then, inductive inference suggests that it will probably rise in the east and set in the west in the future. But how are we to explain our ability to make such an inference? Hume argued that we cannot explain our capacity as a product of our faculty of reason. For reason could only come in two flavours, and neither of these can be used to ground our inferences.

  1. Demonstrative or Intuitive. This sort of reasoning is basically a priori. We cannot determine a priori that the future will be conformable to the past, because it is both (logically) consistent and conceivable that the world stop being uniform. Hume here does not distinguish adequately between the uniformity of nature in general and the persistence of particular regularities. For it is open to a philosopher (perhaps of a Kantian bent) to argue that it is in fact inconceivable that the world not be regular in some ways. However, what is important, and what vindicates Hume, is that for any particular regularity in the operations of nature, it is consistent and conceivable that it might cease. Thus we cannot ground our inductions in a priori reasoning.
  2. Inductive. We cannot appeal, either, to our past successes in using inductive inference, to the fact that it has worked in the past, for this would be circular reasoning.

Hume thus concludes that our inductive practices have no rational foundation, for no form of reason will certify it. However, there are many points to note about what Hume is definitely not saying. He is not saying that induction is not deduction, and thus not rational (i.e. he is not a "deductivist"). For in the Treatise, in a section entitled Of Scepticism with regard to Reason, he argues that if unaided reason determined our beliefs, if belief-formation were rational all the way down, then we would never believe anything, including intuitive or deductive truths. Furthermore, Hume is not saying that induction doesn't work, or doesn't reliably lead to true conclusions, or anything of that sort; rather, he argues just that it isn't spurred on by reason. The important thing to remember with Hume is that although pessimistic about the likelihood of showing that induction was a rational procedure, he thought it was a remarkably accurate—indeed, quasi-magical—ability to predict the future. The fuel for the inductive fire for Hume, and his solution to the problem of explaining our inductions, is Nature. Nature has determined us to expect more of the same, for: "this operation of the mind, by which we infer like effects from like causes, and vice versa, is so essential to the subsistence of all human creatures, it is not probable, that it could be trusted to the fallacious deductions of our reason, which is slow in its operations; appears not, in any degree, during the first years of infancy; and at best is, in every age and period of human life, extremely liable to error and mistake." (ECHU, 5.2.22) This is the closest thing possible during his (pre-Darwinian) time to an evolutionary account of our inductive tendencies, and Hume here has lit on a central feature in any properly atheistic Science of Man, placing him firmly in the naturalist tradition of great thinkers.

The Self: Bundles and Beliefs

Although Hume almost certainly meant it figuratively, his statement that man is "a bundle or collection of different perceptions"[20] has been taken by many quite literally. This interpretation stems from a desire to see Hume as answering the same sort of question about the self that Locke addressed himself to; viz., what counts as an individual person? Locke's answer was that a person is a thinking thing, and that the boundaries of a person stretch as far back as they can remember (though "thinking thing" is not to be taken in the Cartesian sense of being an intellectual substance; Locke thought that we have, and can have, no knowledge of the substantial nature of the self). If this was Hume's question, it might seem reasonable to take his answer to be that the self is just a bundle of perceptions. However, if we interpret him this way, we do him a great disservice, for the view that the self is a bundle of perceptions is deeply flawed. It can be shown to be incorrect with a simple argument: it is logically impossible for two different people to be the same person; it is logically possible for two different people to have the same collections of perceptions; therefore people are not collections of perceptions.

Charity demands, then, that we find a different way of looking at Hume's problem. If we see him as answering an epistemological question — namely, what causes us to form judgements, or beliefs, about the existence of the self? — then we will have more success. Luckily, Hume is quite explicit that this is his question: "What then gives us so great a propension to ascribe an identity to these successive perceptions, and to suppose ourselves possest of an invariable and uninterrupted existence thro' the whole course of our lives?"[21] The problem, then, is that experience is interrupted and ever-changing, but somehow causes us to form a concept of a constant self which is the subject of these experiences. Given that this is Hume's real question, we must also re-interpret his answer. Hume's discussion of personal identity is strongly interlocked with a discussion of the attribution of identity to objects. Roughly, Hume's argument concerning our belief in external objects is that we attribute a continued identity to unperceived objects because resemblances and relations of contiguity and causation in our perceptions force us to form an imaginative picture to the effect that their identity remains intact even when we are not looking. And, he argues, we cannot make sense of the notion of objects existing independently of ourselves unless we have an idea of 'ourself' as something that occasionally becomes aware of these objects. It is the human mind, or consciousness, that is thus conceived of as a field of experience into which various different objects appear and then disappear: "the true idea of the human mind, is to consider it as a system of different perceptions or different existences, which are link'd together by the relation of cause and effect, and mutually produce, destroy, influence, and modify each other."[22] So we are not collections of perceptions (except perhaps metaphorically); we are the subjects of experience, who encounter a world of continuous objects in consciousness.

Instead of the thesis that we are bundles of perceptions, we may attribute Hume with the much more plausible view that our concept of the self is formed alongside our conception of an external world of independently existing objects.

Practical Reason in Hume

Hume's most famous sentence occurs at Treatise, II, III, iii, Of the influencing motives of the will: "Reason is, and ought only to be, slave of the passions, and can never pretend to any other office than to serve and obey them." Hume here extends his anti-rationalism from the epistemological sphere into that of the theory of action, and demonstrates that the faculty of reason cannot, of itself, move the will. He starts the section by going over the by now familiar distinction between demonstrative and probable reasoning (roughly, deductive and inductive reasoning). He then argues that neither can influence the will, as both simply provide information — deductive reasoning about correct mathematical or logical inference and inductive reasoning about causal connections — and it is always open to us as to how to act on this information. Hume then argues that in order to be moved to act on the information provided us by reason, my passions, desires and inclinations must play a role. To take a simple example: using causal reasoning I can discern that if I drink a lot of wine, I will get drunk, but the truth of this conditional will not motivate me to do anything unless I have some desire, in this case the desire to be drunk. As such, Hume forwards the basic folk psychological action-theory that a motive to action requires both a belief (ascertained by the understanding) and a desire (provided by the passions). This theory is still hotly contested, with Humean philosophers such as Simon Blackburn and Michael Smith on one side, and moral cognitivists, like John McDowell, and Kantians, like Christine Korsgaard, on the other.

Sentiment-based ethical theory

Hume first discusses ethics in A Treatise of Human Nature. He later extracts and expounds upon the ideas he proposed there in a s
