Animals – whom we have made our slaves we do not like to consider our equals. – Do not slave holders wish to make the black man other kind?

Few people seem to perceive fully as yet that the most far-reaching consequence of the establishment of the common origin of all species is ethical; that it logically involves a readjustment of altruistic morals, by enlarging, as a necessity of rightness, the application of what has been called ‘The Golden Rule’ from the area of mere mankind to that of the whole animal kingdom. Possibly Darwin himself did not quite perceive it.

While man was deemed to be a creation apart from all other creations, a secondary or tertiary morality was considered good enough to practise towards the ‘inferior’ races; but no person who reasons nowadays can escape the trying conclusion that this is not maintainable.

All the arguments to prove man's superiority cannot shatter this hard fact: In suffering the animals are our equals.
