Wherever morality is based on theology, wherever the right is made dependent on divine authority, the most immoral, unjust, infamous things can be justified and established.

Christianity has in fact long vanished, not only from the reason but also from the life of mankind, and it is nothing more than a fixed idea.

What yesterday was still religion is no longer such today; and what today is atheism, tomorrow will be religion.

Religion is the dream of the human mind. But even in dreams we do not find ourselves in emptiness or in heaven, but on earth, in the realm of reality; we only see real things in the entrancing splendor of imagination and caprice, instead of in the simple daylight of reality and necessity.

Man first unconsciously and involuntarily creates God in his own image, and after this God consciously and voluntarily creates man in his own image.

It is as clear as the sun and as evident as the day that there is no God and that there can be none.

My only wish isto transform friends of God into friends of man, believers into thinkers, devotees of prayer into devotees of work, candidates for the hereafter into students of the world, Christians who, by their own procession and admission, are half animal, half angel into persons, into whole persons.
