“We grew up founding our dreams on the infinite promise of American advertising. I still believe that one can learn to play the piano by mail and that mud will give you a perfect complexion.”
—Zelda Fitzgerald (1900–1948)
“No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.”
—Max Weber (1864–1920)
