Sometimes man creates insightful products based upon all the wrong assumptions. It is as Nietzche quipped, as you stare at the abyss, it also stares at you. As man changed his environment, so too has he been changed by the environment. Man needs to approach his environment in relation to himself and not as if he exists outside it. It seems like the Paleo people consider man to be an immutable being in a constantly changing environment; is it hubris or ignorance?
