“Those who are fired with an enthusiastic idea and who allow it to take hold and dominate their thoughts find that new worlds open for them. As long as enthusiasm holds out, so will new opportunities.”

Context: I do not overlook the fact that there are irrationalists who love mankind, and that not all forms of irrationalism engender criminality. But I hold that he who teaches that not reason but love should rule opens up the way for those who rule by hate. (Socrates, I believe, saw something of this when he suggested that mistrust or hatred of argument is related to mistrust or hatred of man).

Context: Let us, as we value our own self-respect, face the responsibilities with proper seriousness, courage, and high resolve. We must demand the highest order of integrity and ability in our public men who are to grapple with these new problems. We must hold to a rigid accountability those public servants who show unfaithfulness to the interests of the nation or inability to rise to the high level of the new demands upon our strength and our resources. Of course we must remember not to judge any public servant by any one act, and especially should we beware of attacking the men who are merely the occasions and not the causes of disaster.
