“To become a successful leader, you must learn how to tolerate people that don't tolerate you.”

Said during Penn's 1996 acceptance of the Independent Spirit Award for Best Male Lead in Dead Man Walking (1996-03-23)
Penn was making light of his Hollywood reputation as a hothead.
Allusion to quote in Sally Field's 1984 Oscar acceptance speech, which is popularly misremembered as, "You like me. You really like me!"

As quoted in The New York Times (26 September 1982).

Diary entries (1914 - 1974)
Context: The artist is the only one who knows that the world is a subjective creation, that there is a choice to be made, a selection of elements. It is a materialization, an incarnation of his inner world. Then he hopes to attract others into it. He hopes to impose his particular vision and share it with others. And when the second stage is not reached, the brave artist continues nevertheless. The few moments of communion with the world are worth the pain, for it is a world for others, an inheritance for others, a gift to others, in the end. When you make a world tolerable for yourself, you make a world tolerable for others.
We also write to heighten our own awareness of life. We write to lure and enchant and console others. We write to serenade our lovers. We write to taste life twice, in the moment, and in retrospection. We write, like Proust, to render all of it eternal, and to persuade ourselves that it is eternal. We write to be able to transcend our life, to reach beyond it. We write to teach ourselves to speak with others, to record the journey into the labyrinth. We write to expand our world when we feel strangled, or constricted, or lonely. We write as the birds sing, as the primitives dance their rituals. If you do not breathe through writing, if you do not cry out in writing, or sing in writing, then don't write, because our culture has no use for it. When I don't write, I feel my world shrinking. I feel I am in a prison. I feel I lose my fire and my color. It should be a necessity, as the sea needs to heave, and I call it breathing.

The Open Society and Its Enemies (1945)
Context: The so-called paradox of freedom is the argument that freedom in the sense of absence of any constraining control must lead to very great restraint, since it makes the bully free to enslave the meek. The idea is, in a slightly different form, and with very different tendency, clearly expressed in Plato.
Less well known is the paradox of tolerance: Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them. — In this formulation, I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be unwise. But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols. We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. We should claim that any movement preaching intolerance places itself outside the law, and we should consider incitement to intolerance and persecution as criminal, in the same way as we should consider incitement to murder, or to kidnapping, or to the revival of the slave trade, as criminal.
