In the age of technology which now surrounds us, and which boasts of its triumph over nature, one thing is ever more apparent to the anthropologist—the student of man. We have not really conquered nature because we have not conquered ourselves. It is modern man, Homo sapiens, “the wise” as he styles himself, why is now the secret nightmare of man. It is his own long shadow that falls across his restless nights and that follows soundlessly after the pacing feet of statesmen.
~ Loren Eiseley, An Evolutionist Looks at Modern Man
