I have at least, as I hope, done good service in aiding to overthrow the dogma of separate creations.

Delight itself, however, is a weak term to express the feelings of a naturalist.

Whenever I have found that I have blundered, or that my work has been imperfected, and when I have been contemptuously criticised, and even when I have been overpraised, so that I have felt mortified, it has been my greatest comfort to say hundreds of times to myself that 'I have worked as hard as I could, and no man can do more than this.'

At no time am I a quick thinker or writer: whatever I have done in science has solely been by long pondering, patience and industry.

Mr. J.S. Mill speaks, in his celebrated work, "Utilitarianism," of the social feelings as a "powerful natural sentiment," and as "the natural basis of sentiment for utilitarian morality," but on the previous page he says, "if, as is my own belief, the moral feelings are not innate, but acquired, they are not for that reason less natural." It is with hesitation that I venture to differ from so profound a thinker, but it can hardly be disputed that the social feelings are instinctive or innate in the lower animals; and why should they not be so in man?

The moral faculties are generally and justly esteemed as of higher value than the intellectual powers.

It is not the biggest, the brightest or the best that will survive, but those who adapt the quickest.
