I discovered writing was a mighty fine thing. You could make people stand on their hind legs and cast a shadow, and as soon as I discovered it I wanted to bring them all back.
To snatch in a moment of courage, from the remorseless rush of time, a passing phase of life, is only the beginning of the task. The task approached in tenderness and faith is to hold up unquestioningly, without choice and without fear, the rescued fragment before all eyes in the light of a sincere mood. It is to show its vibration, its color, its form; and through its movement, its form, and its color, reveal the substance of its truth — disclose its inspiring secret: the stress and passion within the core of each convincing moment. In a single-minded attempt of that kind, if one be deserving and fortunate, one may perchance attain to such clearness of sincerity that at last the presented vision of regret or pity, of terror or birth, shall awaken in the hearts of the beholders that feeling of unavoidable solidarity; of the solidarity in mysterious origin, in toil, in joy, in hope, in uncertain fate, which binds men to each other and all mankind to the visible world.
Putting aside the need to earn a living, I think there are four great motives for writing, at any rate for writing prose. They exist in different degrees in every writer, and in any one writer the proportions will vary from time to time, according to the atmosphere in which he is living. They are:
Sheer egoism. Desire to seem clever, to be talked about, to be remembered after death, to get your own back on the grown-ups who snubbed you in childhood, etc., etc. It is humbug to pretend this is not a motive, and a strong one. Writers share this characteristic with scientists, artists, politicians, lawyers, soldiers, successful businessmen — in short, with the whole top crust of humanity. The great mass of human beings are not acutely selfish. After the age of about thirty they almost abandon the sense of being individuals at all — and live chiefly for others, or are simply smothered under drudgery. But there is also the minority of gifted, willful people who are determined to live their own lives to the end, and writers belong in this class. Serious writers, I should say, are on the whole more vain and self-centered than journalists, though less interested in money.
Aesthetic enthusiasm. Perception of beauty in the external world, or, on the other hand, in words and their right arrangement. Pleasure in the impact of one sound on another, in the firmness of good prose or the rhythm of a good story. Desire to share an experience which one feels is valuable and ought not to be missed. The aesthetic motive is very feeble in a lot of writers, but even a pamphleteer or writer of textbooks will have pet words and phrases which appeal to him for non-utilitarian reasons; or he may feel strongly about typography, width of margins, etc. Above the level of a railway guide, no book is quite free from aesthetic considerations.
Historical impulse. Desire to see things as they are, to find out true facts and store them up for the use of posterity.
Political purpose. –Using the word ‘political’ in the widest possible sense. Desire to push the world in a certain direction, to alter other peoples’ idea of the kind of society that they should strive after. Once again, no book is genuinely free from political bias. The opinion that art should have nothing to do with politics is itself a political attitude.
It can be seen how these various impulses must war against one another, and how they must fluctuate from person to person and from time to time.
