“"Safety first" has been the motto of the human race for half a million years; but it has never been the motto of leaders. A leader must face danger. He must take the risk and the blame, and the brunt of the storm.”

“You must intervene. You must interfere. And that is actually the motto of human rights.”
Commencement ceremony http://piermarton.info/elie-wiesel-do-not-stand-idly-by-if-you-witness-injustice/ (Class of 2011) at Washington University in St. Louis.
Context: The greatest commandment to me in the Bible is not the Ten Commandments. (First of all, it’s too difficult to observe; second, we all pretend to observe.) My commandment is ‘Thou shall not stand idly by.’ Which means, when you witness an injustice: Don’t stand idly by. When you hear of a person or a group being persecuted: Do not stand idly by. When there is something wrong with the community around you or far away: Do not stand idly by. You must intervene. You must interfere. And that is actually the motto of human rights.

“Alas, criticism has always been what human beings, especially leaders, most hate to hear.”

1920s, The Genius of America (1924)
Context: It is a truism, of course, but it is none the less a fact which we must never forget, that this continent and this American community have been blessed with an unparalleled capacity for assimilating peoples of varying races and nations. The continuing migration which in three centuries has established here this nation of more than a hundred million, has been the greatest that history records as taking place in any such brief period. Viewing it historically, we find that the migration to America was little more than a westward projection of the series of great movements of peoples, by which Europe was given its present population. But there is a striking difference between the migrations into Europe, and the later movements of the same racial elements to the New World.
