Imagination does not breed insanity. Exactly what does breed insanity is reason. Poets do not go mad; but chess-players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not, as will be seen, in any sense attacking logic: I only say that this danger does lie in logic, not in imagination.

So far from the position holding true, that great wit (or genius, in our modern way of speaking), has a necessary alliance with insanity, the greatest wits, on the contrary, will ever be found in the sanest writers. It is impossible for the mind to conceive a mad Shakespeare. The greatness of wit, by which the poetic talent is here chiefly to be understood, manifests itself in the admirable balance of all faculties. Madness is the disproportionate straining or excess of any one of them....The ground of the mistake is, that men, finding in the raptures of the higher poetry a condition of exaltation, to which they have no parallel in their own experience, besides the spurious resemblance of it in dreams and fevers, impute a state of dreaminess and fever to the poet. But the true poet dreams being awake. He is not possessed by his subject, he has dominion over it.

Poetry is sane because it floats easily in an infinite sea; reason seeks to cross the infinite sea, and so make it finite. The result is mental exhaustion. To accept everything is an exercise, to understand everything a strain.

If a man comes to the door of poetry untouched by the madness of the Muses, believing that technique alone will make him a good poet, he and his sane compositions never reach perfection, but are utterly eclipsed by the performances of the inspired madman.

Did I write it so as not to go mad or, on the contrary, to go mad in order to understand the nature of madness?

A poet makes himself a visionary through a long, boundless, and systematized disorganization of all the senses. All forms of love, of suffering, of madness; he searches himself, he exhausts within himself all poisons, and preserves their quintessences. Unspeakable torment, where he will need the greatest faith, a superhuman strength, where he becomes all men the great invalid, the great criminal, the great accursed — and the Supreme Scientist! For he attains the unknown! Because he has cultivated his soul, already rich, more than anyone! He attains the unknown, and if, demented, he finally loses the understanding of his visions, he will at least have seen them! So what if he is destroyed in his ecstatic flight through things unheard of, unnameable: other horrible workers will come; they will begin at the horizons where the first one has fallen!

Someone has defined insanity as an inability to choose among false alternatives. In dreams we are insane. We wander across our limitless dreamscapes as madmen.

If anyone comes to the gates of poetry and expects to become an adequate poet by acquiring expert knowledge of the subject without the Muses' madness, he will fail, and his self-controlled verses will be eclipsed by the poetry of men who have been driven out of their minds.

To say a man does mad things because he is mad is merely unintelligent and stupid. A madman is as logical and reasoned in his action as a sane man — given his peculiar biased point of view. For example, if a man insists on going out and squatting about in nothing but a loin cloth his conduct seems eccentric in the extreme. But once you know that the man himself is firmly convinced that he is Mahatma Gandhi, then his conduct becomes perfectly reasonable and logical.

To be sane in a world of madman is in itself madness.

A major section of modern art and poetry unconsciously guides us in the direction of madness; and, indeed, for the modern man there is no other way. Only madness is inaccessible to the machine.

There is also a third kind of madness, which is possession by the Muses, enters into a delicate and virgin soul, and there inspiring frenzy, awakens lyric....But he, who, not being inspired and having no touch of madness in his soul, comes to the door and thinks he will get into the temple by the help of art — he, I say, and his poetry are not admitted; the sane man is nowhere at all when he enters into rivalry with the madman.

Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad.

Poetry led me by the hand out of madness.
