“He had read much of things as they are, and talked with too many people. Well-meaning philosophers had taught him to look into the logical relations of things, and analyse the processes which shaped his thoughts and fancies. Wonder had gone away, and he had forgotten that all life is only a set of pictures in the brain, among which there is no difference betwixt those born of real things and those born of inward dreamings, and no cause to value the one above the other. Custom had dinned into his ears a superstitious reverence for that which tangibly and physically exists, and had made him secretly ashamed to dwell in visions. Wise men told him his simple fancies were inane and childish, and even more absurd because their actors persist in fancying them full of meaning and purpose as the blind cosmos grinds aimlessly on from nothing to something and from something back to nothing again, neither heeding nor knowing the wishes or existence of the minds that flicker for a second now and then in the darkness.”
H.P. Lovecraft “At the Mountains of Madness” (1936).
