Deism is a religious philosophy and movement that
derives the existence and nature of God from reason and personal experience, in contrast to theism (with religions like Judaism, Christianity and Islam) which relies on revelation in sacred
scriptures or the testimony of other people. Deism became prominent in Great Britain,
France, and the United States in the 17th and 18th centuries and continues to this day in the form of
Classical Deism and Modern Deism.
Deists typically reject supernatural events (prophecy, miracles) and tend to assert that God does not interfere with human
life and the laws of the universe. What organized religions see as divine revelation
and holy books, most Deists see as interpretations made by other humans, rather than as
authoritative sources.
Overview
The concept of Deism covers a wide variety of positions on a wide variety of religious issues. See the section Features of Deism, below. Deism can also refer to a personal set of beliefs having to do with
the role of nature in spirituality.
The words Deism and theism are both derived from the word god:
- The root of the word Deism is the Latin word deus,
which means "god".
- The root of the word theism is the Greek word theos (θεóς), which also
means "god".
Prior to the 17th century the terms ["Deism" and "Deist"] were used interchangeably with the terms "theism" and "theist",
respectively. ... Theologians and philosophers of the seventeenth century began to give a different signification to the
words.... Both [theists and Deists] asserted belief in one supreme God, the Creator.... and agreed that God is personal and
distinct from the world. But the theist taught that god remained actively interested in and operative in the world which he had
made, whereas the Deist maintained that God endowed the world at creation with self-sustaining and self-acting powers and then
abandoned it to the operation of these powers acting as second causes.[1]
A helpful discussion of Deism, theism, and other positions on divine beings can be found in the theism article.
Perhaps the first use of the term Deist is in Pierre Viret's Instruction
Chrestienne (1564), reprinted in Bayle's Dictionnaire entry Viret. Viret,
a Calvinist, regarded Deism as a new form of Italian heresy.[2] Viret wrote:
There are many who confess that while they believe like the Turks and the Jews that there is some sort of God and some sort of
deity, yet with regard to Jesus Christ and to all that to which the doctrine of the Evangelists and the Apostles testify, they
take all that to be fables and dreams.... I have heard that there are of this band those who call themselves Deists, an entirely
new word, which they want to oppose to Atheist. For in that atheist signifies a person who is without God, they want to make it
understood that they are not at all without God, since they certainly believe there is some sort of God, whom they even recognize
as creator of heaven and earth, as do the Turks; but as for Jesus Christ, they only know that he is and hold nothing concerning
him nor his doctrine.
In England, the term Deist first appeared in Robert Burton's The Anatomy of
Melancholy (1621).[3]
Lord Herbert of Cherbury (d. 1648) is generally
considered the "father of English Deism", and his book De Veritate (1624) the first major statement of Deism. Deism
flourished in England between 1690 and 1740, at which time Matthew Tindal's
Christianity as Old as the Creation (1730), or 'the Deist's Bible', gained much attention. Later Deism spread to France,
notably via the work of Voltaire, to Germany, and to America.
Historical background
Deistic thinking has existed since ancient times (e.g., in philosophers such as Heraclitus
and most especially Plato, who envisaged God as the Demiurge or 'craftsman') and in many cultures.
The word Deism is generally used to refer to the movement toward natural
theology or freethinking that occurred in 17th-century Europe, and specifically in
Britain.
Natural theology is a facet of the revolution in world view that occurred in Europe
in the 17th century. To understand the background to that revolution is also to understand the background of Deism. Several
cultural movements of the time contributed to the movement.[4]
The discovery of diversity
The humanist tradition of the Renaissance included a
revival of interest in Europe's classical past in Greece and Rome. With study of the past came a growing awareness that the world
in which the classical authors lived was quite different from the present.
In addition, study of classical documents led to the realization that some historical documents are less reliable than others,
which led to the beginnings of biblical criticism. In particular, as scholars worked
on biblical manuscripts, they began developing the principles of textual criticism and a view of the New Testament as the product
of a particular historical period different from their own.
"Life and works of Confucius", by Prospero Intorcetta, 1687.
In addition to discovering diversity in the past, Europeans discovered diversity in the present. The voyages of discovery of
the 16th and 17th centuries acquainted Europeans with new and different cultures in the Americas, in Asia, and in the Pacific.
They discovered a greater amount of cultural diversity than they had ever imagined, and the question arose of how this vast
amount of human cultural diversity could be compatible with the biblical account of Noah's descendants. In particular, the ideas
of Confucius, translated into European languages by the Jesuits stationed in China, are thought to have had considerable influence on the Deists and other
philosophical groups of the Enlightenment who were interested by the integration
of the system of morality of Confucius into Christianity.[5][6].
In particular, cultural diversity with respect to religious beliefs could no longer be ignored. As Herbert wrote in De
Religione Laici (1645),
Many faiths or religions, clearly, exist or once existed in various countries and ages, and certainly there is not one of them
that the lawgivers have not pronounced to be as it were divinely ordained, so that the Wayfarer finds one in Europe, another in
Africa, and in Asia, still another in the very Indies.
This new awareness of diversity led to a feeling that Christianity was just one religion among many, with no better claim than
any other to correctness.
Religious conflict
Europe had been plagued by vicious sectarian conflicts and religious wars since the beginning of the Reformation. In 1642, when Lord Herbert of Cherbury's De Veritate was published, the
Thirty Years War had been raging on continental Europe for nearly 25 years. It was an
enormously destructive religious war that (it is estimated) destroyed 15–20% of the population of Germany. Closer to home, the
English Civil War pitting King against Parliament was just beginning.
Such massive sectarian violence inspired a visceral rejection of the sectarianism that had led to the violence. It also led to
a search for natural religious truths — truths that could be universally accepted, because they had been either "written in the
book of Nature" or "engraved on the human mind" by God.
Deism also had a great connection to religious toleration.
Advances in scientific knowledge
The 17th century saw a remarkable advance in scientific knowledge: the scientific
revolution. The work of Copernicus, Kepler, and Galileo destroyed the old notion that the
earth was the center of the universe and showed that the universe was incredibly larger than ever imagined. These discoveries
posed a serious challenge to biblical authority and to the religious authorities, Galileo's condemnation for heresy being an especially visible example. In consequence, the
Bible came to be seen as authoritative on matters of faith and morals but no longer authoritative (or meant to be) on matters of
science.
Isaac Newton's discovery of universal gravitation explained the behavior both of objects
here on earth and of objects in the heavens. It promoted a world view in which the natural universe is controlled by laws of
nature. This, in turn, suggested a theology in which God created the universe, set it in motion controlled by natural law, and
retired from the scene. (See the Watchmaker analogy.)
The new awareness of the explanatory power of universal natural law also produced a growing skepticism about such religious
staples as miracles (i.e., violations of natural law) and about books, such as the Bible, that
reported them.
Whereas the Age of Faith found its truths in religious tradition, the Age of Reason found its truths in observable natural
phenomena and individual human reason.
Features of Deism
Critical and constructive Deism
The concept of Deism covers a wide variety of positions on a wide variety of religious issues. Following Sir Leslie Stephen's English Thought in the Eighteenth Century, most commentators agree that two
features constituted the core of Deism:
- The rejection of revealed religion — this was the critical aspect of
Deism.
- The belief that reason, not faith, leads us to certain basic religious truths — this was the positive or constructive
aspect of Deism.
Deist authors advocated a combination of both critical and constructive elements in proportions and emphases that varied from
author to author.
Critical elements of Deist thought included:
- Rejection of all religions based on books that claim to contain the revealed word of God.
- Rejection of reports of miracles, prophecies and religious "mysteries".
- Rejection of the Genesis account of creation and the doctrine of original sin, along with all similar beliefs.
- Rejection of Judaism, Christianity, Islam and other religious beliefs.
Constructive elements of Deist thought included:
- God exists and created the universe.
- God wants human beings to behave morally.
- Human beings have souls that survive death; that is, there is an afterlife.
- In the afterlife, God will reward moral behavior and punish immoral behavior.
Individual Deists varied in the set of critical and constructive elements for which they argued. Some Deists rejected miracles
and prophecies but still considered themselves Christians because they believed in what they felt to be the pure, original form
of Christianity — that is, Christianity as it existed before it was corrupted by additions of such superstitions as miracles,
prophecies, and the doctrine of the Trinity. Some Deists rejected the claim of Jesus' divinity but continued to hold him in high
regard as a moral teacher (see, e.g., Thomas Jefferson's famous Jefferson Bible). Other, more radical Deists rejected Christianity altogether and expressed hostility
toward Christianity, which they regarded as pure superstition. In return, Christian writers often charged radical Deists with
atheism.
Note that the terms constructive and critical are used to refer to aspects of Deistic thought, not sects or
subtypes of Deism — it would be incorrect to classify any particular Deist author as "a constructive Deist" or "a critical
Deist". As Peter Gay notes:
All Deists were in fact both critical and constructive Deists. All sought to destroy in order to build, and reasoned either
from the absurdity of Christianity to the need for a new philosophy or from their desire for a new philosophy to the absurdity of
Christianity. Each Deist, to be sure, had his special competence. While one specialized in abusing priests, another specialized
in rhapsodies to nature, and a third specialized in the skeptical reading of sacred documents. Yet whatever strength the movement
had— and it was at times formidable— it derived that strength from a peculiar combination of critical and constructive
elements.
– Peter Gay, Deism: An Anthology, p. 13
It should be noted, however, that the constructive element of Deism was not unique to Deism. It was the same as the
natural theology that was so prevalent in all English theology in the 17th and 18th
centuries. What set Deists apart from their more orthodox contemporaries was their critical concerns.
Defining the essence of English Deism is a formidable task. Like priestcraft, atheism, and freethinking,
Deism was one of the dirty words of the age. Deists were stigmatized — often as atheists — by their Christian opponents.
Yet some Deists claimed to be Christian, and as Leslie Stephen argued in retrospect, the Deists shared so many fundamental
rational suppositions with their orthodox opponents... that it is practically impossible to distinguish between them. But the
term Deism is nevertheless a meaningful one.... Too many men of letters of the time agree about the essential nature of
English Deism for modern scholars to ignore the simple fact that what sets the Deists apart from even their most latitudinarian Christian contemporaries is their desire to lay aside scriptural revelation as rationally
incomprehensible, and thus useless, or even detrimental, to human society and to religion. While there may possibly be
exceptions, ... most Deists, especially as the eighteenth century wears on, agree that revealed Scripture is nothing but a joke
or "well-invented flam." About mid-century, John Leland, in his historical
and analytical account of the movement [View of the Principal Deistical Writers], squarely states that the rejection of
revealed Scripture is the characteristic element of Deism, a view further codified by such authorities as Ephraim Chambers and Samuel Johnson. ... "DEISM," writes
Stephens bluntly, "is a denial of all reveal'd Religion."
– James E. Force, Introduction (1990) to An Account of the Growth of Deism in England
(1696) by William Stephens
One of the remarkable features of Deism is that the critical elements did not overpower the constructive elements. As E.
Graham Waring observed,[7] "A strange feature of the
[Deist] controversy is the apparent acceptance of all parties of the conviction of the existence of God." And Basil Willey
observed[8]
M. Paul Hazard has recently described the Deists of this time 'as rationalists with nostalgia for religion': men, that is, who
had allowed the spirit of the age to separate them from orthodoxy, but who liked to believe that the slope they had started upon
was not slippery enough to lead them to atheism.
Concepts of "reason"
"Reason" was the ultimate court of appeal for Deists. Tindal's Lockean definitions of reason, self-evident truth, and the light of nature are especially lucid.
By the rational faculties, then, we mean the natural ability a man has to apprehend, judge, and infer: The
immediate objects of which faculties are not the things themselves, but the ideas the mind conceives of them....
Knowledge [is]... nothing but the perception of the agreement or disagreement of our ideas. And any two of these, when
joined together so as to be affirmed or denied of each other, make what we call a proposition... Knowledge accrues either
immediately on the bare intuition of these two ideas or terms so joined, and is therefore styled intuitive
knowledge or self-evident truth, or by the intervention of some other idea or ideas .... this is called
demonstrative knowledge...
If there were not some propositions which need not to be proved, it would be in vain for men to argue with one another [because
there would be no basis for demonstrative reasoning] ... Those propositions which need no proof, we call self-evident; because by
comparing the ideas signified by the terms of such propositions, we immediately discern their agreement, or disagreement: This
is, as I said before, what we call intuitive knowledge.... [Intuitive knowledge] may, I think, be called divine
inspiration as being immediately from God, and not acquired by any human deduction or drawing of consequences: This,
certainly, is that divine, that uniform light, which shines in the minds of all men...
– Matthew Tindal, Christianity as Old as the Creation (II)[9]
Deists did appeal to "the light of nature" to support the self-evident nature of their positive religious claims.
By natural religion, I understand the belief of the existence of a God, and the sense and practice of those duties which
result from the knowledge we, by our reason, have of him and his perfections; and of ourselves, and our own imperfections, and of
the relationship we stand in to him, and to our fellow-creatures; so that the religion of nature takes in everything that is
founded on the reason and nature of things.
I suppose you will allow that it is evident by the light of nature that there is a God, or in other words, a being absolutely
perfect, and infinitely happy in himself, who is the source of all other beings....
– Matthew Tindal, Christianity as Old as the Creation (II)[10]
Once a proposition is asserted to be a self-evident truth, there is not much more to say about it. Consequently, Deist authors
expended most of their ink using reason as a critical tool for exposing and rejecting what they saw as nonsense. Here are two
typical examples. The first is from John Toland's Christianity Not
Mysterious.[11]
I hope to make it appear that the use of reason is not so dangerous in religion as it is commonly represented. ...
There is nothing that men make a greater noise about than the "mysteries of the Christian religion." The divines gravely tell us
"we must adore what we cannot comprehend." Some of them say the "mysteries of the Gospel" are to be understood only in the sense
of the "ancient fathers." ... [Some] contend [that] some mysteries may be, or at least seem to be, contrary to reason, and yet
received by faith. [Others contend] that no mystery is contrary to reason, but that all are "above" it.[12]
On the contrary, we hold that reason is the only foundation of all certitude, and that nothing revealed, whether as to its manner
or existence, is more exempted from its disquisitions than the ordinary phenomena of nature. Wherefore, we likewise maintain,
according to the title of this discourse, that there is nothing in the Gospel contrary to reason, nor above it; and that
no Christian doctrine can be properly called a mystery. ...
Now, as we are extremely subject to deception, we may without some infallible rule, often take a questionable proposition for an
axiom, old wives' fables for moral certitude, and human impostures for divine revelation....
I take it to be very intelligible from the precedent section that what is evidently repugnant to clear and distinct
ideas,[13] or to our common notions,[14] is contrary to reason. ... No Christian that I know of expressly says
reason and the Gospel are contrary to one another. But very many affirm that ... according to our conceptions of them [i.e.
reason and the Gospel] they seem directly to clash. And that though we cannot reconcile them by reason of our corrupt and limited
understandings, yet that from the authority of divine revelation we are bound to believe and acquiesce in them; or, as the
fathers taught them to speak, to "adore what we cannot comprehend." This famous and admirable doctrine is the undoubted source of
all the absurdities that ever were seriously vented among Christians. Without the pretense of it, we should never hear of
transubstantiation, and other ridiculous fables of the Church of Rome. Nor should we
be ever bantered with the Lutheran impanation....
The first thing I shall insist upon is that if any doctrine of the New Testament be contrary to reason, we have no manner of idea
of it. To say, for instance, that a ball is white and black at once is to say just nothing, for these colors are so incompatible
in the same subject as to exclude all possibility of a real positive idea or conception. So to say as the papists that children
dying before baptism are damned without pain signifies nothing at all.
– John Toland, Christianity Not Mysterious: or, a Treatise Shewing That There Is
Nothing in the Gospel Contrary to Reason, Nor above It (1696)
I have known some, who have alleged as a reason why they have forsaken the Christian faith, the impossibility of believing.
Many doctrines (say these) are made necessary to salvation, which 'tis impossible to believe, because they are in their nature
absurdities. I replied, that these things were mysteries, and so above our understanding. But he asked me to what end
could an unintelligible doctrine be revealed? not to instruct, but to puzzle and amuse. What can be the effect of an
unintelligible mystery upon our minds, but only an amusement? That which is only above reason must be above a rational
belief, and must I be saved by an irrational belief? ... You all agree that the belief of your Trinity is absolutely necessary to salvation, and yet widely differ in what we must believe concerning
it; whether three Minds or Modes, or Properties, or internal Relations, or Oeconomies, or Manifestations, or external
Denominations; or else no more than a Holy Three, or Three Somewhats... If I should be persuaded that an explanation of the
Trinity were necessary to save my soul, and see the Learned so widely differing and hotly disputing what it is I must
believe concerning it, I should certainly run mad through despair of finding out the Truth...
– William Stephens, An Account of the Growth of Deism in England (1696), pp.
19-20
Arguments for the existence of God
Thomas Hobbes— an early Deist and important influence on subsequent Deists— used the
cosmological argument for the existence of God at several places in his
writings.
The effects we acknowledge naturally, do include a power of their producing, before they were produced; and that power
presupposeth something existent that hath such power; and the thing so existing with power to produce, if it were not eternal,
must needs have been produced by somewhat before it, and that again by something else before that, till we come to an eternal,
that is to say, the first power of all powers and first cause of all causes; and this is it which all men conceive by the name of
God, implying eternity, incomprehensibility, and omnipotence.
– Thomas Hobbes, Works, vol. 4, pp. 59-60; quoted in John Orr, English Deism,
p. 76
History of religion and the Deist mission
Most Deists saw the religions of their day as corruptions of an original, pure religion that was simple and rational. They
felt that this original pure religion had become corrupted by "priests" who had manipulated it for the priests' personal gain and
for the class interests of the priesthood in general.
According to this world view, over time "priests" had succeeded in encrusting the original simple, rational religion with all
kinds of superstitions and "mysteries" — irrational theological doctrines. Laymen were told by the priests that only the priests
really knew what was necessary for salvation and that laymen must accept the "mysteries" on faith and on the priests' authority.
This kept the laity baffled by the nonsensical "mysteries", confused, and dependent on the priests for information about the
requirements for salvation. The priests consequently enjoyed a position of considerable power over the laity, which they strove
to maintain and increase. Deists referred to this kind of manipulation of religious doctrine as "priestcraft", a highly
derogatory term.
Deists saw their mission as the stripping away of "priestcraft" and "mysteries" from religion, thereby restoring religion to
its original, true condition — simple and rational. In many cases, they considered true, original Christianity to be the same as
this original natural religion. As Matthew Tindal put it:
It can't be imputed to any defect in the light of nature that the pagan world ran into idolatry, but to their being entirely
governed by priests, who pretended communication with their gods, and to have thence their revelations, which they imposed on the
credulous as divine oracles. Whereas the business of the Christian dispensation was to destroy all those traditional revelations,
and restore, free from all idolatry, the true primitive and natural religion implanted in mankind from the creation.
– Matthew Tindal, Christianity as Old as the Creation (XIV)[15]
One implication of this Deist origin myth was that primitive societies, or societies
that existed in the distant past, should have religious beliefs that are less encrusted with superstitions and closer to those of
natural theology. This became a point of attack for thinkers such as David Hume as they studied the "natural history of religion".
Freedom and necessity
Enlightenment thinkers, under the influence of Newtonian science, tended to view the universe as a vast machine, created and
set in motion by a Creator Being, that continues to operate according to natural law, without any divine intervention. This view
naturally led to what was then usually called necessitarianism: the view that
everything in the universe — including human behavior — is completely causally determined by antecedent circumstances and natural
law. (See, e.g., La Mettrie's L'Homme machine.) As a
consequence, debates about freedom versus determinism were a regular feature of
Enlightenment religious and philosophical discussions.
Because of their high regard for natural law and for the idea of a universe without miracles, Deists were especially
susceptible to the temptations of necessitarianism. Reflecting the intellectual climate of the time, there were differences among
Deists about freedom and necessity. Some, such as Anthony Collins, actually were
necessitarians.
Beliefs about immortality of the soul
Deists held a variety of beliefs about the soul. Some, such as Lord Herbert of Cherbury and William
Wollastson,[16] held that souls exist, survive
death, and in the afterlife are rewarded or punished by God for their behavior in life. Others such as Thomas Paine were agnostic about the immortality of the soul:
I trouble not myself about the manner of future existence. I content myself with believing, even to positive conviction, that
the power that gave me existence is able to continue it, in any form and manner he pleases, either with or without this body; and
it appears more probable to me that I shall continue to exist hereafter than that I should have had existence, as I now have,
before that existence began.
– Thomas Paine, The Age of Reason, Part I, Recapitulation
Still others such as Anthony Collins,[17] Bolingbroke, Thomas Chubb, and Peter Annet were materialists and either denied or
doubted the immortality of the soul.[18]
Deist terminology
Deist authors — and 17th- and 18th-century theologians in general — referred to God using a variety of vivid circumlocutions
such as:
The history of Deism
Precursors of Deism
Early works of biblical criticism, such as Thomas
Hobbes's Leviathan and Spinoza's
Theologico-Political Treatise, as well as works by lesser-known authors
such as Richard Simon and Isaac La Peyrère,
paved the way for the development of critical Deism.
Early Deism
Lord Herbert of Cherbury (d. 1648) is generally
considered the "father of English Deism", and his book De Veritate (On Truth, as It Is Distinguished from Revelation,
the Probable, the Possible, and the False) (1624) the first major statement of Deism.[19][20]
Like his contemporary Descartes, Herbert searched for the foundations of knowledge. In fact, the first two thirds of De
Veritate are devoted to an exposition of Herbert's theory of knowledge. Herbert distinguished truths obtained through
experience, and through reasoning about experience, from innate truths and from revealed truths. Innate truths are imprinted on
our minds, and the evidence that they are so imprinted is that they are universally accepted. Herbert's term for universally
accepted truths was notitiae communes — common notions.
In the realm of religion, Herbert believed that there were five common notions.
- There is one Supreme God.
- He ought to be worshipped.
- Virtue and piety are the chief parts of divine worship.
- We ought to be sorry fo
