There are some who esteem that it is a naivety to believe that a moral regeneration may be possible ("soit possible", Fr.); now, if this was not the case, it would not be worth the trouble that humanity continue to vegetate without aim.
Justice has nothing to do with expediency. Justice has nothing to do with any temporary standard whatever. It is rooted and grounded in the fundamental instincts of humanity.
The truth is, of course, that the curtness of the Ten Commandments is an evidence, not of the gloom and narrowness of a religion, but, on the contrary, of its liberality and humanity. It is shorter to state the things forbidden than the things permitted; precisely because most things are permitted, and only a few things are forbidden.
Eratosthenes was the director of the great library of Alexandria, the Centre of science and learning in the ancient world. Aristotle had argued that humanity was divided into Greeks and everybody else, whom he called barbarians and that the Greeks should keep themselves racially pure. He thought it was fitting for the Greeks to enslave other peoples. But Erathosthenes criticized Aristotle for his blind chauvinism, he believed there was good and bad in every nation.
It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from regard to their own interest. We address ourselves, not to their humanity but to their self-love, and never talk to them of our own necessities but of their advantages. Nobody but a beggar chooses to depend chiefly upon the benevolence of his fellow citizens.
