Man Is The Sole Animal Whose Nudities Offend His Own Companions, And The
Only One Who, In His Natural Actions, Withdraws And Hides Himself From His
Own Kind.
Man is the sole animal whose nudities offend his own companions, and the
only one who, in his natural actions, withdraws and hides himself from his
own kind.
-- Montaigne, "Apology for Raymond Sebonde"
