“One has got to choose between the two evils, also between the lesser of the two evils in the matter of food, and therefore vegetarian food has got to be taken by man in order to sustain human life”

"No, Not One," The Adelphi (October 1941), p. 7 http://books.google.com/books?id=hdwYAQAAIAAJ&q=%22The+choice+before+human+beings%22&pg=PA7#v=onepage- 8 http://books.google.com/books?id=hdwYAQAAIAAJ&q=%22is+not+as+a+rule+between+good+and+evil+but+between+two+evils%22&pg=PA8#v=onepage
Context: The choice before human beings, is not, as a rule, between good and evil but between two evils. You can let the Nazis rule the world: that is evil; or you can overthrow them by war, which is also evil. There is no other choice before you, and whichever you choose you will not come out with clean hands.

As quoted in Margaret Mead : Some Personal Views (1979) edited by Rhoda Métraux
As quoted in American Quotations (1992) by Gorton Carruth and Eugene H. Ehrlich
1970s
Variant: At times it may be necessary temporarily to accept a lesser evil, but one must never label a necessary evil as good.
