Only in books has mankind known perfect truth, love and beauty.

The only truth is music.

Experiment is the sole source of truth. It alone can teach us something new; it alone can give us certainty.

In the end, only the truth will survive.

The Cross of Christ is the only gateway to knowledge.

Experiment is the only means of knowledge at our disposal. Everything else is poetry, imagination.

Literature is, to my mind, the great teaching power of the world, the ultimate creator of all values, and it is this, not only in the sacred books whose power everybody acknowledges, but by every movement of imagination in song or story or drama that height of intensity and sincerity has made literature at all. Literature must take the responsibility of its power, and keep all its freedom: it must be like the spirit and like the wind that blows where it listeth; it must claim its right to pierce through every crevice of human nature, and to descrive the relation of the soul and the heart to the facts of life and of law, and to describe that relation as it is, not as we would have it be...

The only defense against the world is a thorough knowledge of it.

Truth is the only merit that gives dignity and worth to history.

An honest story is at home in one, and only one, place and time.

You have to start with the truth. The truth is the only way that we can get anywhere. Because any decision-making that is based upon lies or ignorance can't lead to a good conclusion.

"Literature "has always been the last refuge, in this world, for those who do not know where to lay their dreaming heads.

Certitude belongs exclusively to those who only own one encyclopedia.

Truth can prevail only in virtue of truth itself.
