Paradox

Paradox should have a paradoxical definition, but not all apparent contradictions are paradoxical, nor are all absurdities. The paradox in paradox is found in its conflicting meanings: a truth seemingly absurd; a self-falsifying statement; anyone or anything apparently contradictory or inconsistent. Contradiction seems to happen mostly with words (or concepts) belonging to the same generic or hyperonym, as in »A circle is a square« (the inclusive term being »figure«). Inserting an epithet or equivalent may dissipate the inconsistency: »A circle is a planed-down square.«

I always feel that, for this particularly difficult concept, someone should have invented a word that read the same in both directions. Bertrand Russell, Gottlob Frege, are you out there...??
