A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life merely for the sake of his appetite. And to act so is immoral.

There can be only one permanent revolution- a moral one: the regeneration of the inner man.

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

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

The highest possible stage in moral culture is when we recognise that we ought to control our thoughts.

A moral being is one who is capable of reflecting on his past actions and their motives - of approving of some and disapproving of others.
