Variant: There comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because conscience tells him it is right.

Context: On some positions, Cowardice asks the question, "Is it safe?" Expediency asks the question, "Is it politic?" And Vanity comes along and asks the question, "Is it popular?" But Conscience asks the question "Is it right?" And there comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must do it because Conscience tells him it is right.

I believe today that there is a need for all people of good will to come together with a massive act of conscience and say in the words of the old Negro spiritual, "We ain't goin' study war no more." This is the challenge facing modern man.

World War Z
Context: You wanna know who lost World War Z? Whales. I guess they never really had a chance, not with several million hungry boat people and half the world's navies converted to fishing fleets. [... ] So the next time someone tries to tell you about how the true losses of this war are "our innocence" or "part of our humanity"... Whatever, bro. Tell it to the whales.
