  2. Something that is clearly established or assured: "On the field of battle there are no certainties" (Tom Clancy).

SYNONYMS   certainty, certitude, assurance, conviction. These nouns mean freedom from doubt. Certainty implies a thorough consideration of evidence: "the emphasis of a certainty that is not impaired by any shade of doubt" (Mark Twain). Certitude is based more on personal belief than on objective facts: "Certitude is not the test of certainty" (Oliver Wendell Holmes, Jr.). Assurance is a feeling of confidence resulting from subjective experience: "There is no such thing as absolute certainty, but there is assurance sufficient for the purposes of human life" (John Stuart Mill).

Psychoanalysis: Certainty
Top

An internal moral conviction resulting from reflection, or subjectively imposed in the form of an intuition or illumination, certainty is an intellectual sentiment that transposes sensory evidence into the realm of thought. Sigmund Freud gave little thought to the concept except when considering its opposite, doubt, or as related to the idea of conviction, which connotes an illusory or mistaken content (delusional conviction). However, dreams are an example of a mental product accompanied by certainty since images, rather than judgments, are involved. Conversely, whenever there is doubt, it is the misrepresentation that underscores the ability of the element in question to convey meaning.

It is especially in the area of superstition and knowledge of the paranormal that Freud investigated the notion of certainty. As with paranoid delirium, he sees its origin in a projection of the contents of the unconscious onto the outside world (1901b). This idea was developed in connection with animist thought and later with the category of experience, which included feelings of seeing or experiencing something one has seen or experienced before (déjà-vu and déjà-vécu) (1914a), and feelings of alienation (Entfremdung), or the uncanny (Unheimlichkeit). What is in question in all of these are "obsolete primal convictions" associated with a primal inability to differentiate between the ego and the outside world.

Freud's analysis of religious feelings—what Romain Rolland refers to as oceanic feelings (1930a [1929])—provided him with an opportunity to question whether certainty is equivalent to an objective perception. These feelings, he wrote, are "described as feelings but are apparently complicated processes associated with determinate contents and decisions concerning those contents." The only things that are certain are death and the relation between the mother (certissima [absolutely certain]) and the child, while the father is semper incertus (always uncertain). The fantasy of certainty, which the most skeptical researcher is never without, can thus be associated with this experience of primary and irreplaceable assurance: that of being the mother's child. What is certain is irreplaceable. For Freud, the psychoanalyst is prepared "for the sake of attaining some fragment of objective certainty, to sacrifice everything—the dazzling brilliance of a flawless theory, the exalted consciousness of having achieved a comprehensive view of the universe, the mental calm brought about by the possession of extensive grounds for expedient and ethical action" (1941d [1921], pp. 179). This spiritual abstinence is not based on an obsessive predilection for uncertainty but, on the contrary, a desire of anticipated certainty, of possessing fragmentary crumbs of knowledge once and for all (Mijolla-Mellor, S., 1992).

The concept of certainty in psychoanalysis appears to be related both to the analysis of illusion associated with desire (Freud); or, more radically, with the destruction of critical thought, the seductive appeal of deviation, where the only possibility is one of repetition (Aulagnier,1984), and to the always partial and painfully won acquisition of partial certainties incorporated in a renewed hypothetical-deductive approach.

A related article is titled uncertainty.
For statistical certainty, see probability.

Certainty can be defined as either (a) perfect knowledge that has total security from error, or (b) the mental state of being without doubt. Objectively defined, certainty is total continuity and validity of all foundational inquiry, to the highest degree of precision. Something is certain only if no skepticism can occur. Philosophy (at least historically) seeks this state.[citation needed] It is widely held that certainty is a failed historical enterprise.[1]

History

Socrates- ancient Greece

Socrates, often thought to be the first true philosopher, had a higher criterion for knowledge than others before him. The skeptical problems that he encountered in his philosophy were taken very seriously. As a result, he claimed to know nothing. Socrates often said that his wisdom was limited to an awareness of his own ignorance.

Al-Ghazali- Islamic theologian

Al-Ghazali was a professor of philosophy in the 11th century. His book titled The Incoherence of the Philosophers marks a major turn in Islamic epistemology, as Ghazali effectively discovered philosophical skepticism that would not be commonly seen in the West until René Descartes, George Berkeley and David Hume. He described the necessity of proving the validity of reason- independently from reason. He attempted this and failed. The doubt that he introduced to his foundation of knowledge could not be reconciled using philosophy. Taking this very seriously, he resigned from his post at the university, and suffered serious psychosomatic illness. It was not until he became a religious sufi that he found a solution to his philosophical problems, which are based on Islamic religion; this encounter with skepticism led Ghazali to embrace a form of theological occasionalism, or the belief that all causal events and interactions are not the product of material conjunctions but rather the immediate and present will of God.

Descartes- 17th Century

Descartes' Meditations on First Philosophy is a book in which Descartes first discards all belief in things which are not absolutely certain, and then tries to establish what can be known for sure. Although the phrase "Cogito, ergo sum" is often attributed with Descartes' Meditations on First Philosophy it is actually put forward in his Discourse on Method however, due to the implications of inferring the conclusion within the predicate, he changed the argument to "I think, I exist"; this then becomes his first certainty.

Ludwig Wittgenstein- 20th Century

On Certainty is a series of notes made by Ludwig Wittgenstein just prior to his death. The main theme of the work is that context plays a role in epistemology. Wittgenstein asserts an anti-foundationalist message throughout the work: that every claim can be doubted but certainty is possible in a framework. "The function [propositions] serve in language is to serve as a kind of framework within which empirical propositions can make sense".[2]

Degrees of Certainty

See inductive logic, philosophy of probability, philosophy of statistics.

Rudolph Carnap viewed certainty as a matter of degree (degrees of certainty) which could be objectively measured, with degree one being certainty. Bayesian analysis derives degrees of certainty which are interpreted as a measure of subjective psychological belief.

Foundational crisis of mathematics

The foundational crisis of mathematics was the early 20th century's term for the search for proper foundations of mathematics.

After several schools of the philosophy of mathematics ran into difficulties one after the other in the 20th century, the assumption that mathematics had any foundation that could be stated within mathematics itself began to be heavily challenged.

One attempt after another to provide unassailable foundations for mathematics was found to suffer from various paradoxes (such as Russell's paradox) and to be inconsistent.

Various schools of thought on the right approach to the foundations of mathematics were fiercely opposing each other. The leading school was that of the formalist approach, of which David Hilbert was the foremost proponent, culminating in what is known as Hilbert's program, which thought to ground mathematics on a small basis of a formal system proved sound by metamathematical finitistic means. The main opponent was the intuitionist school, led by L. E. J. Brouwer, which resolutely discarded formalism as a meaningless game with symbols[citation needed]. The fight was acrimonious. In 1920 Hilbert succeeded in having Brouwer, whom he considered a threat to mathematics, removed from the editorial board of Mathematische Annalen, the leading mathematical journal of the time.

Gödel's incompleteness theorems, proved in 1931, showed that essential aspects of Hilbert's program could not be attained. In Gödel's first result he showed how to construct, for any sufficiently powerful and consistent finitely axiomatizable system – such as necessary to axiomatize the elementary theory of arithmetic – a statement that can be shown to be true, but that does not follow from the rules of the system. It thus became clear that the notion of mathematical truth can not be reduced to a purely formal system as envisaged in Hilbert's program. In a next result Gödel showed that such a system was not powerful enough for proving its own consistency, let alone that a simpler system could do the job. This dealt a final blow to the heart of Hilbert's program, the hope that consistency could be established by finitistic means (it was never made clear exactly what axioms were the "finitistic" ones, but whatever axiomatic system was being referred to, it was a *weaker* system than the system whose consistency it was supposed to prove). Meanwhile, the intuitionistic school had failed to attract adherents among working mathematicians, and floundered due to the difficulties of doing mathematics under the constraint of constructivism.

In a sense, the crisis has not been resolved, but faded away: most mathematicians either do not work from axiomatic systems, or if they do, do not doubt the consistency of ZFC, generally their preferred axiomatic system. In most of mathematics as it is practiced, the various logical paradoxes never played a role anyway, and in those branches in which they do (such as logic and category theory), they may be avoided.

Quotes

Doubt is not a pleasant condition, but certainty is absurd.
 
In this world nothing can be said to be certain, except death and taxes.
 
There is no such thing as absolute certainty, but there is assurance sufficient

for the purposes of human life.

 
If you tried to doubt everything you would not get as far as doubting anything. The game of doubting itself presupposes certainty.
