“It is surprising with what impunity and comfort one who has always lain in a warm bed in a close apartment, and studiously avoided drafts of air, can lie down on the ground without a shelter, roll himself in a blanket, and sleep before a fire, in a frosty autumn night, just after a long rain-storm, and even come soon to enjoy and value the fresh air.”
—Henry David Thoreau (1817–1862)

“When we say “science” we can either mean any manipulation of the inventive and organizing power of the human intellect: or we can mean such an extremely different thing as the religion of science the vulgarized derivative from this pure activity manipulated by a sort of priestcraft into a great religious and political weapon.”
—Wyndham Lewis (1882–1957)
