— Francois de la Rochefoucauld

Do your damnedest in an ostentatious manner all the time.
George S. Patton ostentatiously quote

Whoever wishes to attain an English style, familiar but not coarse, and elegant but not ostentatious, must give his days and nights to the volumes of Addison.
— Samuel Johnson

Let us speak, though we show all our faults and weaknesses, --for it is a sign of strength to be weak, to know it, and out with it -- not in a set way and ostentatiously, though, but incidentally and without premeditation.
— Herman Melville

An ostentatious man will rather relate a blunder or an absurdity he has committed, than be debarred from talking of his own dear person.
— ostentatiously quotation by Joseph Addison
