axiomatic

An axiom is a principle widely accepted on the basis of its intrinsic merit or one regarded as self-evidently true. A statement that is axiomatic therefore, is one against which few people would argue. "Axiomatic" entered English from Middle Greek axiōmatikos, and "axiom" derived via Latin from Greek axiōma ("something worthy") and "axios" ("worthy"). The word axiom can also refer to a statement accepted as true as the basis for argument or inference. Such axioms are often employed in discussions of philosophy, as well as in mathematics and geometry (where they are sometimes called postulates).
