“A very great deal more truth can become known than can be proven.”

Paul Tanner, in "Free Women: 1"<!-- p. 173 -->
The Golden Notebook (1962)
Context: We spend our lives fighting to get people very slightly more stupid than ourselves to accept truths that the great men have always known. They have known for thousands of years that to lock a sick person into solitary confinement makes him worse. They have known for thousands of years that a poor man who is frightened of his landlord and of the police is a slave. They have known it. We know it. But do the great enlightened mass of the British people know it? No. It is our task, Ella, yours and mine, to tell them. Because the great men are too great to be bothered. They are already discovering how to colonise Venus and to irrigate the moon. That is what is important for our time. You and I are the boulder-pushers. All our lives, you and I, we’ll put all our energies, all our talents into pushing a great boulder up a mountain. The boulder is the truth that the great men know by instinct, and the mountain is the stupidity of mankind.

The Antichrist (1888)
Context: Hope, in its stronger forms, is a great deal more powerful stimulans to life than any sort of realized joy can ever be. Man must be sustained in suffering by a hope so high that no conflict with actuality can dash it—so high, indeed, that no fulfilment can satisfy it: a hope reaching out beyond this world.

Context: You cannot find truth through anybody else. How can you? Surely, truth is not something static; it has no fixed abode; it is not an end, a goal. On the contrary, it is living, dynamic, alert, alive. How can it be an end? If truth is a fixed point, it is no longer truth; it is then a mere opinion. Sir, truth is the unknown, and a mind that is seeking truth will never find it. For mind is made up of the known; it is the result of the past, the outcome of time — which you can observe for yourself. Mind is the instrument of the known; hence it cannot find the unknown; it can only move from the known to the known. When the mind seeks truth, the truth it has read about in books, that "truth" is self-projected, for then the mind is merely in pursuit of the known, a more satisfactory known than the previous one. When the mind seeks truth, it is seeking its own self-projection, not truth. After all, an ideal is self-projected; it is fictitious, unreal. What is real is what is, not the opposite. But a mind that is seeking reality, seeking God, is seeking the known. When you think of God, your God is the projection of your own thought, the result of social influences. You can think only of the known; you cannot think of the unknown, you cannot concentrate on truth. The moment you think of the unknown, it is merely the self-projected known. So, God or truth cannot be thought about. If you think about it, it is not truth. Truth cannot be sought; it comes to you. You can go after only what is known. When the mind is not tortured by the known, by the effects of the known, then only can truth reveal itself. Truth is in every leaf, every tear; it is to be known from moment to moment. No one can lead you to truth; and if anyone leads you, it can only be to the known.

The Paris Review interview
Context: Many writers write a great deal, but very few write more than a very little of the real thing. So most writing must be displaced activity. When cockerels confront each other and daren’t fight, they busily start pecking imaginary grains off to the side. That’s displaced activity. Much of what we do at any level is a bit like that, I fancy. But hard to know which is which. On the other hand, the machinery has to be kept running. The big problem for those who write verse is keeping the machine running without simply exercising evasion of the real confrontation. If Ulanova, the ballerina, missed one day of practice, she couldn’t get back to peak fitness without a week of hard work. Dickens said the same about his writing—if he missed a day he needed a week of hard slog to get back into the flow.
