The year 2100 will see eugenics universally established. In past ages, the law governing the survival of the fittest roughly weeded out the less desirable strains. Then man's new sense of pity began to interfere with the ruthless workings of nature. As a result, we continue to keep alive and to breed the unfit. The only method compatible with our notions of civilization and the race is to prevent the breeding of the unfit by sterilization and the deliberate guidance of the mating instinct, Several European countries and a number of states of the American Union sterilize the criminal and the insane. This is not sufficient. The trend of opinion among eugenists is that we must make marriage more difficult. Certainly no one who is not a desirable parent should be permitted to produce progeny. A century from now it will no more occur to a normal person to mate with a person eugenically unfit than to marry a habitual criminal.

Love isn’t about predictions or behavioural markers. It just happens, and you have no control.

Like the weather or bonds between lovers, transformations cannot always be predicted. All energy transmutes one day or another, in one way or another. Either in its form or composition, or in its position or disposition.

However, robust evidence shows that people systematically overestimate the probability of positive future contingencies, and underestimate the probability of negative ones — only those who are depressed or dysphoric come to accurate assessments.

It sounds like a fairy-tale, but not only that; this story of what man by his science and practical inventions has achieved on this earth, where he first appeared as a weakly member of the animal kingdom, and on which each individual of his species must ever again appear as a helpless infant... Is a direct fulfilment of all, or of most, of the dearest wishes in his fairy-tales. All these possessions he has acquired through culture. Long ago he formed an ideal conception of omnipotence and omniscience which he embodied in his gods. Whatever seemed unattainable to his desires - or forbidden to him - he attributed to these gods. One may say, therefore, that these gods were the ideals of his culture. Now he has himself approached very near to realizing this ideal, he has nearly become a god himself. But only, it is true, in the way that ideals are usually realized in the general experience of humanity. Not completely; in some respects not at all, in others only by halves. Man has become a god by means of artificial limbs, so to speak, quite magnificent when equipped with all his accessory organs; but they do not grow on him and they still give him trouble at times... Future ages will produce further great advances in this realm of culture, probably inconceivable now, and will increase man's likeness to a god still more.

The future is like a corridor into which we can see only by the light coming from behind.

If America and the Western world continue in their state of unconscious hopelessness, lack of faith and of fortitude, it is predictable that they will not be able to resist the temptation of the big bang by nuclear weapons, which would end all problems - overpopulation, boredom, and hunger - since it would do away with all life.

That Muhammad could predict certain events does not prove that he was a prophet: he may have been able to guess successfully, but this does not mean that he had real knowledge of the future. And certainly the fact that he was able to recount events from the past does not prove that he was a prophet, because he could have read about those events in the Bible and, if he was illiterate, he could still have had the Bible read to him.

If a palmist grasp my palm, and look into it, without seeing a single line, what would he read?

You couldn’t predict what was going to happen for one simple reason: people.
