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

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.

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.

Sympathy beyond the confines of man, that is, humanity to the lower animals, seems to be one of the latest moral acquisitions.

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

Physiological experiment on animals is justifiable for real investigation; but not for mere damnable and detestable curiosity.
