I say, beware of all enterprises that require new clothes . . . When I ask for a garment of a particular form, my tailoress tells me gravely, "They do not make them so now," not emphasizing the "They" at all, as if she quoted an authority as impersonal as the Fates . . . We worship not the Graces, nor the Parcae, but Fashion. She spins and weaves and cuts with full authority. The head monkey at Paris puts on a traveller's cap, and all the monkeys in America do the same . . .—Walden

It is with science as with ethics,—we cannot know truth by contrivance and method; the Baconian is as false as any other, and with all the helps of machinery and the arts, the most scientific will still be the healthiest and friendliest man, and possess a more perfect Indian wisdom.—"Natural History of Massachusetts"
One sentence of perennial poetry would make me forget—would atone for volumes of mere science.—Journal, 5 August 1851
One studies books of science merely to learn the language of naturalists—to be able to communicate with them.—Journal, 23 March 1853
Science is always brave, for to know, is to know good; doubt and danger quail before her eyes. What the coward overlooks in his hurry, she calmly scrutinizes, breaking ground like a pioneer for the array of arts that follow her train.—"Natural History of Massachusetts"
