Michel de Montaigne

French Renaissance thinker and writer best known for his "Essays". On the theme that small learning makes for presumption, great learning for humility, he wrote "To really learned men has happened what happens to ears of wheat: they rise high and lofty, head erect and proud, as long as they are empty; but when they are full and swollen with grain in their ripeness, they begin to grow humble and lower their horns."
