AXIOM (Gr. &iwµa)  , a See also:general proposition or principle accepted as self-evident, either absolutely or within a particular See also:sphere of thought . Each See also:special See also:science has its own axioms (cf. the Aristotelian &pxai, " first principles"), which, however, are sometimes susceptible of See also:proof in another wider science . The See also:Greek word was probably confined by See also:Plato to mathematical axioms, but See also:Aristotle (Anal . See also:Post. i . 2) gave it also the wider significance of the ultimate principles of thought which are behind all special sciences (e.g. the principle of See also:contradiction) . These are apprehended solely by the mind, which may, however, be led to them by an inductive See also:process . After Aristotle, the See also:term was used by the See also:Stoics and the school of See also:Ramus for a proposition simply, and See also:Bacon {Nov . See also:Organ. i . 7) used it of any general proposition . The word was reintroduced in See also:modern See also:philosophy probably by Rene See also:Descartes (or by his followers)who, in the See also:search for a definite self-evident principle as the basis of a new philosophy, naturally turned to the See also:familiar science of See also:mathematics . The See also:axiom of See also:Cartesianism is, therefore, the Cogito ergo sum . See also:Kant still further narrowed the meaning to include only self-evident (intuitive) synthetic propositions, i.e. of space and See also:time .

The nature of axiomatic certainty is See also:

part of the fundamental problem of See also:logic and See also:metaphysics . Those who deny the possibility of all non-empirical knowledge naturally hold that every axiom is ultimately based on observation . For the Euclidian axioms see See also:GEOMETRY .
