Famous quotes containing the word weakness:
“Just as in habiliments it is a sign of weakness to wish to make oneself noticeable by some peculiar and unaccustomed fashion, so, in language, the quest for new-fangled phrases and little-known words comes from a puerile and pedantic ambition.”
—Michel de Montaigne (1533–1592)
