The sexual impulse is the strongest force in all living creatures. It is this that animates the struggle for existence; it is this that attracts and unites two beings, that they may reproduce their kind; it is this that inspires man to the highest and noblest thoughts; it is this that also inspires man to all endeavors and achievements, to all art and poetry; this impulse is the creative instinct which dominates all living things and without which life must die.
