And ye shall know the truth, and the truth shall make you free.

"Faith" means not wanting to know what is true.

If you're going to tell people the truth, you better make them laugh; otherwise they'll kill you.

We have art in order not to die of the truth.

In the mountains of truth you will never climb in vain: either you will get up higher today or you will exercise your strength so as to be able to get up higher tomorrow.

What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding.

There always comes a time in history when the person who dares to say that 2+2=4 is punished by death. And the issue is not what reward or what punishment will be the outcome of that reasoning. The issue is simply whether or not 2+2=4.

Love truth, but pardon error.

Truth, in the matters of religion, is simply the opinion that has survived.

A thing is not necessarily true because a man dies for it.

I believe it is an established maxim in morals that he who makes an assertion without knowing whether it is true or false, is guilty of falsehood; and the accidental truth of the assertion, does not justify or excuse him.

That faith makes blessed under certain circumstances, that blessedness does not make of a fixed idea a true idea, that faith moves no mountains but puts mountains where there are none: a quick walk through a madhouse enlightens one sufficiently about this.

To what extent can truth endure incorporation? That is the question; that is the experiment.

The various languages placed side by side show that with words it is never a question of truth, never a question of adequate expression; otherwise, there would not be so many languages. The "thing in itself" (which is precisely what the pure truth, apart from any of its consequences, would be) is likewise something quite incomprehensible to the creator of language and something not in the least worth striving for. This creator only designates the relations of things to men, and for expressing these relations he lays hold of the boldest metaphors.

What men avoid by excluding the liar is not so much being defrauded as it is being harmed by means of fraud. Thus, even at this stage, what they hate is basically not deception itself, but rather the unpleasant, hated consequences of certain sorts of deception. It is in a similarly restricted sense that man now wants nothing but truth: he desires the pleasant, life-preserving consequences of truth.

A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value.

The absurd is the essential concept and the first truth.

We too often forget that not only is there "a soul of goodness in things evil," but very generally also, a soul of truth in things erroneous.
