“The average Ph.D. thesis is nothing but a transference of bones from one graveyard to another.”
—J. Frank Dobie (1888–1964)
“It is a mass language only in the same sense that its baseball slang is born of baseball players. That is, it is a language which is being molded by writers to do delicate things and yet be within the grasp of superficially educated people. It is not a natural growth, much as its proletarian writers would like to think so. But compared with it at its best, English has reached the Alexandrian stage of formalism and decay.”
—Raymond Chandler (1888–1959)
“And yet these Rarities might be allow’d,
To Man, that sov’raign thing and proud;
Had he not dealt between the Bark and Tree,
Forbidden mixtures there to see.
No Plant now knew the Stock from which it came;
He grafts upon the Wild the Tame:”
—Andrew Marvell (1621–1678)
