“Despite the Great Chain of Being's traditional ranking of humans between animals and angels, there is no evolutionary justification for the common assumption that evolution is somehow 'aimed' at humans, or that humans are 'evolution's last word'.”

“The talent for self-justification is surely the finest flower of human evolution, the greatest achievement of the human brain. When it comes to justifying actions, every human being acquires the intelligence of an Einstein, the imagination of a Shakespeare, and the subtlety of a Jesuit.”

“Evolution brings human beings. Human beings, through a long and painful process, bring humanity.”

“An evolutionary morality argues that The North was right in pursuing that war because a nation is a higher form of evolution than a human body and the principle of human equality is an even higher form than a nation”

“sound is of no use to human evolution. in fact, it gets in the way.”

“The history of humanity is the history of human freedom...Freedom is not, as Engels thought, "the recognition of necessity." Freedom is the opposite of necessity. Freedom is necessity overcome. Progress is, in essence, the progress of human freedom. Yes, and after all, life itself is freedom. The evolution of life is the evolution of freedom.”
