Besides love and sympathy, animals exhibit other qualities connected with the social instincts which in us would be called moral.

It is a good instinct if you don't distort it and pervert it. Don't give it up. Keep feeling the need for being important. Keep feeling the need for being first. But I want you to be the first in love. I want you to be the first in moral excellence. I want you to be the first in generosity.

If man fails to reorientate his life around moral and ethical values he may well destroy himself by the misuse of his own instrument.

Morality is the herd-instinct in the individual.

A moral system valid for all is basically immoral.

Who is the most moral man? First, he who obeys the law most frequently, who ... is continually inventive in creating opportunities for obeying the law. Then, he who obeys it even in the most difficult cases. The most moral man is he who sacrifices the most to custom.
