“It seemed there was a sort of poisoning, an auto-infection of the organisms, so Dr. Krokowski said; it was caused by the disintegration of a substance ... and the products of this disintegration operated like an intoxicant upon the nerve-centres of the spinal cord, with an effect similar to that of certain poisons, such as morphia, or cocaine.”
—Thomas Mann (1875–1955)
“We are the products of editing, rather than of authorship.”
—George Wald (b. 1906)
“Good wine needs no bush,
And perhaps products that people really want need no
hard-sell or soft-sell TV push.
Why not?
Look at pot.”
—Ogden Nash (1902–1971)
