To say that authority, whether secular or religious, supplies no ground for morality is not to deny the obvious fact that it supplies a sanction.
Morality is a private and costly luxury.
Property is not the sacred right. When a rich man becomes poor it is a misfortune, it is not a moral evil. When a poor man becomes destitute, it is a moral evil, teeming with consequences and injurious to society and morality.
