Postulate \Pos"tu*late\, n. [L. postulatum a demand, request,
prop. p. p. of postulare to demand, prob. a dim. of poscere
to demand, prob. for porcscere; akin to G. forschen to
search, investigate, Skr. prach to ask, and L. precari to
pray: cf. F. postulat. See Pray.]
1. Something demanded or asserted; especially, a position or
supposition assumed without proof, or one which is
considered as self-evident; a truth to which assent may be
demanded or challenged, without argument or evidence.
2. (Geom.) The enunciation of a self-evident problem, in
distinction from an axiom, which is the enunciation of a
self-evident theorem.
The distinction between a postulate and an axiom
lies in this, -- that the latter is admitted to be
self-evident, while the former may be agreed upon
between two reasoners, and admitted by both, but not
as proposition which it would be impossible to deny.
--Eng. Cyc.
