Human desire tends to be insatiable.

If human pleasure did not have both a lid and a time limit, we would not bestir ourselves to do things that were not pleasurable, such as toiling for our subsistence. And then we would not survive. By the same token, should our mass mind ever become discontented with the restricted pleasures doled out by nature, as well as disgruntled over the lack of restrictions on pain, we would omit the mandates of survival from our lives out of a stratospherically acerbic indignation. And then we would not reproduce. As a species, we do not shout into the sky, “The pleasures of this world are not enough for us.” In fact, they are just enough to drive us on like oxen pulling a cart full of our calves, which in their turn will put on the yoke. As inordinately evolved beings, though, we can postulate that it will not always be this way. “A time will come,” we say to ourselves, “when we will unmake this world in which we are battered between long burden and brief delight, and will live in pleasure for all our days.” The belief in the possibility of long-lasting, high-flown pleasures is a deceptive but adaptive flimflam. It seems that nature did not make us to feel too good for too long, which would be no good for the survival of the species, but only to feel good enough for long enough to keep us from complaining that we do not feel good all the time.

The flesh receives as unlimited the limits of pleasure; and to provide it requires unlimited time. But the mind, intellectually grasping what the end and limit of the flesh is, and banishing the terrors of the future, procures a complete and perfect life, and we have no longer any need of unlimited time. Nevertheless the mind does not shun pleasure, and even when circumstances make death imminent, the mind does not lack enjoyment of the best life. (20)

Man's desires are, indeed, innumerable, often hopeless, and sometimes vile, but they may all be rolled together into two: the desire to avoid pain, and the desire to experience pleasure. Every conscious movement made by living beings, from oyster to philosopher, is directed toward the accomplishment of one or both of these ends.

There is no craving or demand of the human mind more constant and insatiable than that for exercise and employment, and this desire seems the foundation of most of our passions and pursuits.

The trouble is, the human brain isn’t designed to make us happy and fulfilled. It’s designed to make us survive. This two-million-year-old organ is always looking for what’s wrong, for whatever can hurt us, so that we can either fight it or take flight from it. If you and I leave this ancient survival software to run the show, what chance do we have of enjoying life?

The capacity of the brain to forsee the future has much to do with the fear of death.
For when the body is worn out and the brain is tired, the whole organism welcomes death. But it is difficult to understand how death can be welcome when you are young and strong, so that you come to regard it as a dread and terrible event. For the brain, in its immaterial way, looks into the future and conceives it a good to go on and on and on forever — not realizing that its own material would at last find the process intolerably tiresome. Not taking this into account, the brain fails to see that, being itself material and subject to change, its desires will change, and a time will come when death will be good. On a bright morning, after a good night’s rest, you do not want to go to sleep. But after a hard day’s work the sensation of dropping into unconsciousness is extraordinarily pleasant.

Normally pleasure is never the goal of human strivings but rather is, and must remain, an effect, more specifically, the side effect of attaining a goal. Attaining the goal constitutes a reason for being happy. In other words, if there is a reason for happiness, happiness ensues, automatically and spontaneously, as it were. And that is why one need not pursue happiness, one need not care for it once there is a reason for it. Figure 3 But, even more, one cannot pursue it. To the extent to which one makes happiness the objective of his motivation, he necessarily makes it the object of his attention. But precisely by so doing he loses sight of the reason for happiness, and happiness itself must fade away.

If we are to have intense pleasures, we must also be liable to intense pains. The pleasure we love, and the pain we hate, but it seems impossible to have the former without the latter. Indeed, it looks as if the two must in some way alternate, for continuous pleasure is a stimulus that must either pall or be increased. And the increase will either harden the sense buds with its friction, or turn into pain. A consistent diet of rich food either destroys the appetite or makes one sick.

"This is why modern civilization is in almost every respect a vicious circle. It is insatiably hungry because its way of life condemns it to perpetual frustration. [...] [T]he root of this frustration is that we live for the future, and the future is an abstraction, a rational inference from experience, which exists only for the brain. The "primary consciousness," the basic mind which knows reality rather than ideas about it, does not know the future. It lives completely in the present, and perceives nothing more that what is at this moment. The ingenious brain, however, looks at that part of present experience called memory, and by studying it is able to make predictions. These predictions are, relatively, so accurate and reliable (e.g., "everyone will die") that the future assumes a high degree of reality - so high that the present loses its value."

Thus the “brainy” economy designed to produce this happiness is a fantastic vicious circle which must either manufacture more and more pleasures or collapse — providing a constant titillation of the ears, eyes, and nerve ends with incessant streams of almost inescapable noise and visual distractions. The perfect “subject” for the aims of this economy is the person who continuously itches his ears with the radio, preferably using the portable kind which can go with him at all hours and in all places. His eyes flit without rest from television screen, to newspaper, to magazine, keeping him in a sort of orgasm-with-out-release through a series of teasing glimpses of shiny automobiles, shiny female bodies, and other sensuous surfaces, interspersed with such restorers of sensitivity — shock treatments — as “human interest” shots of criminals, mangled bodies, wrecked airplanes, prize fights, and burning buildings. The literature or discourse that goes along with this is similarly manufactured to tease without satisfaction, to replace every partial gratification with a new desire. For this stream of stimulants is designed to produce cravings for more and more of the same, though louder and faster, and these cravings drive us to do work which is of no interest save for the money it pays — to buy more lavish radios, sleeker automobiles, glossier magazines, and better television sets, all of which will somehow conspire to persuade us that happiness lies just around the corner if we will buy one more. Despite the immense hubbub and nervous strain, we are convinced that sleep is a waste of valuable time and continue to chase these fantasies far into the night. Animals spend much of their time dozing and idling pleasantly, but, because life is short, human beings must cram into the years the highest possible amount of consciousness, alertness, and chronic insomnia so as to be sure not to miss the last fragment of startling pleasure. It isn’t that the people who submit to this ki

What I am emphasizing is that we are trying to solve our basic human problems through a psychological framework, when actually the problem is neurological. The body is involved. Take desire. As long as there is a living body, there will be desire. It is natural. Thought has interfered and trying to suppress, control, and moralize about desire, to the detriment of mankind. We are trying to solve the ‘problem’ of desire through thought. It is thinking that has created the problem.

For what man has sought for is, indeed, neither pain nor pleasure, but simply Life. Man has sought to live intensely, fully, perfectly. When he can do so without exercising restraint on others, or suffering it ever, and his activities are all pleasurable to him, he will be saner, healthier, more civilised, more himself. Pleasure is Nature's test, her sign of approval. When man is happy, he is in harmony with himself and his environment.

There is something ridiculous and even quite indecent in an individual claiming to be happy. Still more a people or a nation making such a claim. The pursuit of happiness… is without any question the most fatuous which could possibly be undertaken. This lamentable phrase ‘’the pursuit of happiness'’ is responsible for a good part of the ills and miseries of the modern world.
