Few people fail in love so spectacularly as great philosophers. Despite our admiration for their wisdom, history is littered with romantic failures of the most sensible men and women of every age, including:
Friedrich Nietzsche: "Oh, women. They make successes higher and lower more frequent." (Everyone who proposed to him turned him down, even as he kept asking and asking.)
Jean-Paul Sartre: "There are, of course, ugly women, but I prefer beautiful ones." (His lover adopted a daughter.)
Louis Althusser: “The problem is that there are bodies and, even worse, sexual organs.” (accidentally strangled his wife to death).
and scores of other great thinkers whose words we revere--but whose romantic decisions we must avoid at all costs.
