If we knew that god exists, such knowledge would make morality impossible. For, if we acted morally from fear or fright, or confident of a reward, then this would not be moral. It would be enlightened selfishness.
Certain beliefs must accompany every action: One should act without selfishness, cultivate compassion for all living things, and develop respect for others.
By developing a sense of respect for others and a concern for their welfare, we reduce our own selfishness, which is the source of all problems, and enhance our sense of kindness, which is a natural source of goodness.
The State must act as the guardian of a millennial future in the face of which the wishes and the selfishness of the individual must appear as nothing and submit.
