“That’s the great danger of sectarian opinions, they always accept the *formulas* of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”

—John Dos Passos (1896–1970)

“The pace of science forces the pace of technique. Theoretical physics forces *atomic* energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.”

—Erich Fromm (1900–1980)
