Never give up, which is the lesson I learned from boxing. As soon as you learn to never give up, you have to learn the power and wisdom of unconditional surrender, and that one doesn't cancel out the other; they just exist as contradictions. The wisdom of it comes as you get older.

Contradiction is not a sign of falsity, nor the lack of contradiction a sign of truth.

In contradiction and paradox, you can find truth.

When I write down my thoughts, they do not escape me. This action makes me remember my strength which I forget at all times. I educate myself proportionately to my captured thought. I aim only to distinguish the contradiction between my mind and nothingness.

I've come to the conclusion that beautiful women in the West aren't comfortable finding strength in their femininity. They want to do masculine-oriented things to establish their femininity. It's a contradiction.

My biggest flaw is probably my attention span or lack thereof. And while it might seem contradictory, my biggest strength is my work ethic.

Evangelicals always assume that humor and faith are contradictory. It's OK to smile, to be nice, but not frivolous.

To the indefinite, uncertain mind of the American radical the most contradictory ideas and methods are possible. The result is a sad chaos in the radical movement, a sort of intellectual hash, which has neither taste nor character.

Is it not a species of blasphemy to call the New Testament revealed religion, when we see in it such contradictions and absurdities.

Certainly a sort of industrial use of creatures, so that geese are fed in such a way as to produce as large a liver as possible, or hens live so packed together that they become just caricatures of birds, this degrading of living creatures to a commodity seems to me in fact to contradict the relationship of mutuality that comes across in the Bible.

Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them.

Attempts to settle crises by unilateral sanctions outside the framework of U.N. Security Council decisions threaten international peace and stability. Such attempts are counterproductive and contradict the norms and principles of international law.

Part of me is drawn to the nature of sadness because I think life is sad, and sadness is not something that should be avoided or denied. It's a fact of life, like contradictions are.

In live action movies, you just hope that everything works. Because the actor may had a bad morning and doesn't play good, or accidents happen continuously. Many things contradict what you are trying to say. But in cartoons, nothing contradict what you want to say.

Good morning is a contradiction of terms.

The 'morality of compromise' sounds contradictory. Compromise is usually a sign of weakness, or an admission of defeat. Strong men don't compromise, it is said, and principles should never be compromised.

I know that some consider it controversial for me to claim that God saved my life when I had received an experimental drug and some of the greatest medical care available in the world. I can see how these two realities appear to contradict each other.

Even putting aside the Judeo-Christian morality upon which the Constitution and our nation's culture are based, the notion of forced euthanasia would contradict the long-held body of medical ethics to which all American doctors must adhere.

Only by learning to live in harmony with your contradictions can you keep it all afloat.

The cardinal responsibility of leadership is to identify the dominant contradiction at each point of the historical process and to work out a central line to resolve it.

As liberty and intelligence have increased the people have more and more revolted against the theological dogmas that contradict common sense and wound the tenderest sensibilities of the soul.

Military intelligence is a contradiction in terms.

Nothing manifests more persuasively the American contradiction than that the author of the Declaration of Independence, a slave owner, wrote an antislavery clause into the document - as if to compel himself to be better than he was - which then had to be edited out so the Southern states, including Thomas Jefferson's own, would sign it.

Just as discipline and freedom are opposing forces that must be balanced, leadership requires finding the equilibrium in the dichotomy of many seemingly contradictory qualities between one extreme and another.
