“[Responding to the Bishop of Oxford, Samuel Wilberforce's question whether he traced his descent from an ape on his mother's or his father's side]A man has no reason to be ashamed of having an ape for his grandfather. If there were an ancestor whom I should feel shame in recalling it would rather be a man—a man of restless and versatile intellect—who … plunges into scientific questions with which he has no real acquaintance, only to obscure them by an aimless rhetoric, and distract the attention of his hearers from the real point at issue by eloquent digressions and skilled appeals to religious prejudice.”

“It is only natural, of course, that each man should think his own opinions best: the crow loves his fledgling, and the ape his cub.”

“Agnosticism is of the essence of science, whether ancient or modern. It simply means that a man shall not say he knows or believes that which he has no scientific grounds for professing to know or believe. Consequently Agnosticism puts aside not only the greater part of popular theology, but also the greater part of anti-theology. On the whole, the "bosh" of heterodoxy is more offensive to me than that of orthodoxy, because heterodoxy professes to be guided by reason and science, and orthodoxy does not.”

“Every man who knows how to read has it in his power to magnify himself, to multiply the ways in which he exists, to make his life full, significant and interesting.”

“Every man with a little leisure and enough money for railway tickets, every man, indeed, who knows how to read, has it in his power to magnify himself, to multiply the ways in which he exists, to make his life full, significant and interesting.”

“Indeed, a faint hypnopædic prejudice in favour of size was universal. Hence the laughter of the women to whom he made proposals, the practical joking of his equals among the men. The mockery made him feel an outsider; and feeling an outsider he behaved like one, which increased the prejudice against him and intensified the contempt and hostility aroused by his physical defects. Which in turn increased his sense of being alien and alone. A chronic fear of being slighted made him avoid his equals, made him stand, where his inferiors were concerned, self-consciously on his dignity.”

“Science is nothing but trained and organized common sense, differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only as far as the guardsman's cut and thrust differ from the manner in which a savage wields his club.”
