Axiom

nounPronunciation: /ˈæk.si.əm/

In Portuguese: Axioma

What does “Axiom” mean?

A proposition or statement accepted as true without proof, serving as a premise for further reasoning. In logic, it forms the foundation of deductive systems.

Etymology

From Middle French axiome, from Latin axioma, from Greek axioma, "that which is thought worthy or fitting", and hence a principle taken as self-evident, from axioun ("to think worthy"), from axios ("worthy"). The word came into English in the late 15th century. In Greek mathematics and philosophy it named the propositions that need no proof and from which demonstration starts. Modern logic uses it for any statement taken as a starting point of a formal system.

Usage note

Outside logic and mathematics the word is used loosely for any principle that a group treats as beyond question.

Synonyms

  • postulate
  • premise
  • principle
  • maxim
  • truism
  • dictum

Often confused with

postulate
In the classical distinction an axiom is a truth common to all sciences, while a postulate is an assumption proper to one field; modern usage often treats them as the same.
