“He who cannot howl will not find his pack.”

Riverside Sermons (1958)

The Philosophical Emperor, a Political Experiment, or, The Progress of a False Position: (1841)
Context: Man soon finds what he wants to find. If he cannot find it otherwise, he creates it for his special enjoyment: for instance, if a man wants to see a ghost, he need only promulge his wish some night around a decaying fire, with a few alarmed and shocked listeners. Then let him ascend in the dark to a remote chamber, carefully looking over his shoulder every few moments; and if he will not see a ghost, he will feel as if he saw one, and that will be tantamount thereto.

"On the Educational Value of the Natural History Sciences" (1854) http://aleph0.clarku.edu/huxley/CE3/EdVal.html
1850s
Context: I cannot but think that he who finds a certain proportion of pain and evil inseparably woven up in the life of the very worms, will bear his own share with more courage and submission; and will, at any rate, view with suspicion those weakly amiable theories of the Divine government, which would have us believe pain to be an oversight and a mistake, — to be corrected by and by. On the other hand, the predominance of happiness among living things — their lavish beauty — the secret and wonderful harmony which pervades them all, from the highest to the lowest, are equally striking refutations of that modern Manichean doctrine, which exhibits the world as a slave-mill, worked with many tears, for mere utilitarian ends.
There is yet another way in which natural history may, I am convinced, take a profound hold upon practical life, — and that is, by its influence over our finer feelings, as the greatest of all sources of that pleasure which is derivable from beauty.
