"Religion is a disease. It is born of fear; it compensates through hate in the guise of authority, revelation. Religion, enthroned in a powerful social organization, can become incredibly sadistic. No religion has been more cruel than the Christian."

The Renaissance had resulted in the emancipation of the individual, in making him feel that the universe had no other purpose than his happiness. This brought an entirely new answer to the question, 'Why should I do this or that?' It used to be, 'Because self-instituted authority command you.' The answer now was, 'Because it is good for men.' In this lies our greatest debt to the Renaissance, that it instituted the welfare of men as the end of all action.
