In the vocabulary of certain radical theorists contradictions are given the status of some deadly disease to which their opponents alone can succumb. But contradictions are the very stuff of life. If there had been a little dash of contradiction among the Gadarene swine some of them might have been saved from drowning.

Meaning lies in the confrontation of contradiction - the coincidencia apositorum. That’s what we really feel, not these rational schemes that are constantly beating us over the head with the “thou shalts” and “thou should”, but rather a recovery of the real ambiguity of being and an ability to see ourselves as at once powerful and weak, noble and ignoble, future-oriented, past-facing.

I'll give you a hint. Contradictions do not exist. Whenever you think that you are facing a contradiction, check your premises. You will find that one of them is wrong.

I have often had occasion to notice how, where a direct question would fail to elicit a response, a false assumption brings instant information in the form of a contradiction.

I like contradictions. We have never attained the infinite variety and contradictions that exist in nature. Tomorrow I shall contradict myself. That is the one way I have of asserting my liberty, the real liberty one does not find as a member of society.

When a contradiction is impossible to resolve except by a lie, then we know that it is really a door.

The 'paradox' is only a conflict between reality and your feeling of what reality 'ought to be'.

We can only learn and advance with contradictions.
The faithful inside should meet the doubtful. The doubtful should meet the faithful. Human slowly advances and becomes mature when he accepts his contradictions.

What is defeat? Nothing but education; nothing but the first step to something better.

Victory is an illusion of philosophers and fools.

Contradiction is the external limit of the propositions, tautology their substanceless centre.

Tautology and contradiction are, however, not senseless; they are part of the symbolism, in the same way that “0” is part of the symbolism of Arithmetic.

not merely to be defeated, but to acknowledge defeat — and the difference between these two things is what keeps the world going.

Truth is paradox.
