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.

The moral faculties are generally esteemed, and with justice, as of higher value than the intellectual powers. But we should always bear in mind that the activity of the mind in vividly recalling past impressions is one of the fundamental though secondary bases of conscience. This fact affords the strongest argument for educating and stimulating in all possible ways the intellectual faculties of every human being.

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

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