I could see clearly that this problem could only be solved on the individual and personal level; political revolt is irrelevant. Both Camus and Sartre had been neatly hog-tied by their earlier radicalism. Camus came to see that rebellion is a political roundabout that revolves back to the same old tyranny; too ashamed to admit that he had outgrown his leftism, he found himself in an intellectual cul-de-sac. Sartre accused Camus of being a reactionary; but he paid for his own refusal to reexamine his political convictions by congealing into a grotesque attitude of permanent indignation, shaking his fist at some abstract Authority. Where politics is concerned, he seemed determined to be guided by his emotions.

One simple method is to take a pen or pencil and hold it up against a blank wall or ceiling. Now concentrate on the pen as if it is the most important thing in the world. Then allow your sense to relax, so you see the pen against the background of the wall. Concentrate again. Relax again. Keep on doing this until you become aware of the ability to focus attention at will. You will find that this unaccustomed activity of the will is tiring; it produces a sense of strain behind the eyes. My own perception is that if you persist, in spite of the strain, the result is acute discomfort, followed by a sudden immense relief - the 'peak experience'.

In fact, we had a number of extreme leftists and trade unionists among us, and they seemed to take it for granted that we all agreed that the rich must somehow be forced to surrender their ill-gotten gains. Yet there was an air of good humor about their idealism that made me feel they would not be too offended if I admitted that I regard socialists as well-meaning but muddle-headed brigands.

And at once I saw with great clarity that human beings possess two bodies. One is the physical body, the other -- just as real, just as self-contained -- is the emotional body. Like the physical body, the emotional body reaches a certain level of growth, and then stops. But it stops rather sooner than the physical body. So most of us possess the emotional body of a retarded adolescent.

This provides us with our first major clue to the solutions of the problem. Even if the left cannot see the world as full of potentiality, it can hold on to the moments of insight and refuse to let go of them. If I know that present difficulties will end in triumph, I am un-discourageable; I merely have to know it intellectually. And if I can 'know' that reality actually has a third dimension, I shall never fall into the mistake of complaining that there is nothing new under the sun and that life is futile.

You', the ego, live in your left brain. When we say that man is the only creature who spends 99 per cent of his time inside his own head, we mean, in fact, inside his left cerebral hemisphere. And in the basement of the left hemisphere is the library full of filing cabinets -- the stuffy room that we mistake for reality.

We have all experienced the moments that William James calls melting moods, when it suddenly becomes perfectly obvious that life is infinitely fascinating. And the insight seems to apply retrospectively. Periods of my life that seemed confusing and dull at the time now seem complex and rather charming. It is almost as if some other person a more powerful and mature individual has taken over my brain. This higher self views my problems and anxieties with kindly detachment, but entirely without pity. Looking at problems through his eyes, I can see I was a fool to worry about them.

This is a strange -- and rather alarming -- realisation. For it clearly implies that masturbation is one of our highest faculties that human beings have developed. Many animals masturbate -- but never without the presence of another animal, or some similar stimulus. A human being can masturbate in an empty room: a triumph of pure imagination.

This in turn suggests an answer to our question: what happened between the birth of De Sade and the birth of Krafft-Ebbing? The rise of the novel taught Europe to use its imagination. And when imagination was applied to sex, the result was the rise of pornography -- and of "sexual perversion."

Sex also concentrates the mind wonderfully, and that is why civilised man is so obsessed by it. It enables him to "savour every fraction of an inch," not merely of the act of sexual intercourse, but of living itself. But that, of course, only underlines the basic problem: after coitus, "man becomes sad," because he quickly returns to his unconcentrated and defocused state. In sexual excitement, it is the spirit itself that becomes erect, and becomes capable of penetrating the meaning of life. Normal consciousness is limp and flaccid; its attitude towards reality is defensive. This is what Sartre called contingency, that feeling of being at the mercy of chance.
