“For reason, on the one hand, signifies the idea of a free, human social life. On the other hand, reason is the court of judgment of calculation, the instrument of domination, and the means for the greatest exploitation of nature.”

“It is my firm conviction that man has nothing to gain, emotionally or otherwise, by adhering to a falsehood, regardless of how comfortable or sacred that falsehood may appear. Anyone who claims, on the one hand, that he is concerned with human welfare, and who demands, on the other hand, that man must suspend or renounce the use of his reason, is contradicting himself. There can be no knowledge of what is good for man apart from knowledge of reality and human nature, and there is no manner in which this knowledge can be acquired except through reason. To advocate irrationality is to advocate that which is destructive to human life.”

“The social view of humanity, namely that of social ecology, focuses primarily on the historic emergence of hierarchy and the need to eliminate hierarchical relationships. It emphasizes the just demands of the oppressed in a society that wantonly exploits human beings, and it calls for their freedom. It explores the possibility or a new technology and a new sensibility, including more organic forms of reason, that will harmonize our relationship with nature instead of opposing society to the natural world.”

“The ultimate ends of the activities of reasonable beings are never economic. Money is one of the greatest instruments of freedom ever invented by man.”

“The greatest danger that besets us does not come from believers or atheists; it comes from those who, under the guise of religion, science or reason, imagine that we can free ourselves from the limitations of human nature and perfect the human species.”

“We have reason to believe that man first walked upright to free his hands for masturbation.”
