" I racked my brains to discover some sense in the events I had witnessed. I needed this intellectual exercise to escape from the despair that haunted me, to prove to myself that I was a man, I mean a man from Earth, a reasoning creature who made it a habit to discover a logical explanation for the apparently miraculous whims of nature, and not a beast hunted down by highly developed apes. "

― Pierre Boulle , Planet of the Apes
