Humanity has in the course of time had to endure from the hands of science two great outrages upon its naive self-love. The first was when it realized that our earth was not the center of the universe, but only a speck in a world-system of a magnitude hardly conceivable... The second was when biological research robbed man of his particular privilege of having been specially created, and relegated him to a descent from the animal world.-- Sigmund Freud
