Did you know?

An axiom is a principle widely accepted for 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 the New Latin word axiōmaticus, and like axiom, it comes ultimately from the Greek word axíōma, meaning (among other things) “that which is reasonable (though not demonstrated to be true).” The word axiom can also refer to a statement accepted as true specifically as the basis for an argument or inference. An example would be: “Nothing can both be and not be at the same time and in the same respect.” Such axioms are often employed in philosophy, as well as in mathematics and geometry, where they are sometimes called postulates.
