anypotheton

Etymology

From Ancient Greek ανυπόθετον (anupótheton), negation of Ancient Greek ὑπόθεσις (hupóthesis, “base, basis of an argument, supposition”, literally “a placing under”), itself from ὑπό (hupó, “below”) + τίθημι (títhēmi, “I put, place”).

Why this word is great

ANYPOTHETON — [Noun] A self-evident truth or foundational principle requiring no further validation, particularly in Platonic philosophy. From Ancient Greek ανυπόθετον (anupótheton, "not based on a hypothesis"), from ἀν- (an-, "not") + ὑπόθεσις (hupóthesis, "base, supposition"), itself from ὑπό (hupó, "under") + τίθημι (títhēmi, "to put, place"). Unlike "hypothesis" (a tentative claim awaiting proof) or "supposition" (an unexamined assumption), an anypotheton is bedrock—the kind of truth that, once grasped, cannot be unthought. It is the geometric certainty that two parallel lines never meet, the moral intuition that cruelty is wrong, or the silent understanding that consciousness exists—not because we prove it, but because we cannot meaningfully doubt it. Some truths are not built; they simply are.

noun

An idea which is discovered to be true in itself, or which supports itself; that which is absolutely or necessarily true; as opposed to a hypothesis requiring further support. The result or conclusion of a philosophical argument or investigation according to Plato's "hypothetical method."“Only the supreme science, dialectics, attempts to justify these hypotheses by reducing them to the first principle, the Good, which is itself anypotheton, unconditional.”
