“The great enemy of truth is very often not the lie–deliberate, contrived and dishonest–but the myth–persistent, persuasive and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.[Commencement Address at Yale University, June 11 1962]”

“It’s not about going around trying to stir up trouble. As long as you’re honest and you articulate what you believe to be true, somebody somewhere will become your enemy whether you like it or not.”

“…when two opposite points of view are expressed with equal intensity, the truth does not necessarily lie exactly halfway between them. It is possible for one side to be simply wrong.”

“Never judge someone’s character based on the words of another. Instead, study the motives behind the words of the person casting the bad judgment. An honest woman can sell tangerines all day and remain a good person until she dies, but there will always be naysayers who will try to convince you otherwise. Perhaps this woman did not give them something for free, or at a discount. Perhaps too, that she refused to stand with them when they were wrong — or just stood up for something she felt was right. And also, it could be that some bitter women are envious of her, or that she rejected the advances of some very proud men. Always trust your heart. If the Creator stood before a million men with the light of a million lamps, only a few would truly see him because truth is already alive in their hearts. Truth can only be seen by those with truth in them. He who does not have Truth in his heart, will always be blind to her.”

“If by any chance a playwright wishes to express a political opinion or a moral opinion or a philosophy, he must be a good enough craftsman to do it with so much spice of entertainment in it that the public get the message without being aware of it.”

“For where is the man that has incontestable evidence of the truth of all that he holds, or of the falsehood of all he condemns; or can say that he has examined to the bottom all his own, or other men’s opinions? The necessity of believing without knowledge, nay often upon very slight grounds, in this fleeting state of action and blindness we are in, should make us more busy and careful to inform ourselves than constrain others.”

“Stupidity is much the same all the world over. A stupid person’s notions and feelings may confidently be inferred from those which prevail in the circle by which the person is surrounded. Not so with those whose opinions and feelings are an emanation from their own nature and faculties.”

“A sin is nothing more than regret. Not for doing it once, but doing it again when you know you’re going to regret it.”

“In this age, the mere example of non-conformity, the mere refusal to bend the knee to custom, is itself a service. Precisely because the tyranny of opinion is such as to make eccentricity a reproach, it is desirable, in order to break through that tyranny, that people should be eccentric. Eccentricity has always abounded when and where strength of character has abounded; and the amount of eccentricity in a society has generally been proportional to the amount of genius, mental vigor, and moral courage which it contained. That so few now dare to be eccentric, marks the chief danger of the time.”

“It is clear that the individual who persecutes a man, his brother, because he is not of the same opinion, is a monster.”

“Your opinion is not my reality.”

“I agree with yours of the 22d that a professorship of Theology should have no place in our institution. but we cannot always do what is absolutely best. those with whom we act, entertaining different views, have the power and the right of carrying them into practice. truth advances, & error recedes step by step only; and to do to our fellow-men the most good in our power, we must lead where we can, follow where we cannot, and still go with them, watching always the favorable moment for helping them to another step.[Comment on establishing Jefferson’s University of Virginia, a secular college, in a letter to Thomas Cooper 7 October 1814]”

“You’ll have a good, secure life when being alive means more to you than security, love more than money, your freedom more than public or partisan opinion, when the mood of Beethoven’s or Bach’s music becomes the mood of your whole life … when your thinking is in harmony, and no longer in conflict, with your feelings … when you let yourself be guided by the thoughts of great sages and no longer by the crimes of great warriors … when you pay the men and women who teach your children better than the politicians; when truths inspire you and empty formulas repel you; when you communicate with your fellow workers in foreign countries directly, and no longer through diplomats…”

“If you fuel your journey on the opinions of others, you are going to run out of gas.”
