The fact that the general incidence of leukemia has doubled in the last two decades may be due, partly, to the increasing use of x-rays for numerous purposes. The incidence of leukemia in doctors, who are likely to be so exposed, is twice that of the general public. In radiologists the incidence is ten times greater.

To two men living the same number of years, the world always provides the same sum of experiences. It is up to us to be conscious of them.

The needs of a human being are sacred. Their satisfaction cannot be subordinated either to reasons of state, or to any consideration of money, nationality, race, or colour, or to the moral or other value attributed to the human being in question, or to any consideration whatsoever. There is no legitimate limit to the satisfaction of the needs of a human being except as imposed by necessity and by the needs of other human beings. The limit is only legitimate if the needs of all human beings receive an equal degree of attention.

As soon as the soul has been made to perceive that a thing can conduct it to that which it loves supremely, it must inevitably embrace it with joy.

I have been writing & speaking what were once called novelties, for twenty five or thirty years, & have not now one disciple. Why? Not that what I said was not true; not that it has not found intelligent receivers but because it did not go from any wish in me to bring men to me, but to themselves. I delight in driving them from me. What could I do, if they came to me? - they would interrupt and encumber me. This is my boast that I have no school & no follower. I should account it a measure of the impurity of insight, if it did not create independence.

In relation to any act of life, the mind acts as a killjoy.

These examples point to the third and most fundamental aspect of the incommensurability of competing paradigms. In a sense that I am unable to explicate further, the proponents of competing paradigms practice their trades in different worlds. One contains constrained bodies that fall slowly, the other pendulums that repeat their motions again and again. In one, solutions are compounds, in the other mixtures. One is embedded in a flat, the other in a curved, matrix of space. Practicing in different worlds, the two groups of scientists see different things when they look from the same point in the same direction. Again, that is not to say that they can see anything they please. Both are looking at the world, and what they look at has not changed. But in some areas they see different things, and they see them in different relations one to the other. That is why a law that cannot even be demonstrated to one group of scientists may occasionally seem intuitively obvious to another. p. 149

Society and conversation, therefore, are the most powerful remedies for restoring the mind to its tranquillity, if, at any time, it has unfortunately lost it; as well as the best preservatives of that equal and happy temper, which is so necessary to self-satisfaction and enjoyment. Men of retirement and speculation, who are apt to sit brooding at home over either grief or resentment, though they may often have more humanity, more generosity, and a nicer sense of honour, yet seldom possess that equality of temper which is so common among men of the world.

Though the profusion of Government must undoubtedly have retarded the natural progress of England to wealth and improvement, it has not been able to stop it.

War involves in its progress such a train of unforeseen and unsupposed circumstances ... that no human wisdom can calculate the end. Prospects on the Rubicon

I disclose my mysteries to those who are worthy of my mysteries.

Youth instinctively understand the present environment - the electric drama. It lives mythically and in depth.

I now come to the second reason for the modern fading of interest in religion. Religion is the reaction of human nature to its search for God. The presentation of God under the aspect of power awakens every modern instinct of critical reaction. This is fatal; for religion collapses unless its main positions command immediacy of assent. In this respect the old phraseology is at variance with the psychology of modern civilisations. This change in psychology is largely due to science, and is one of the chief ways in which the advance of science has weakened the hold of the old religious forms of expression.

Rules necessary for definitions. Not to leave any terms at all obscure or ambiguous without definition; Not to employ in definitions any but terms perfectly known or already explained.

If you punish him for what he sees you practise yourself, he... will be apt to interpret it the peevishness and arbitrary imperiousness of a father, who, without any ground for it, would deny his son the liberty and pleasure he takes himself.

It is trifling to believe in what you do or in what others do. You should avoid simulacra and even "realities"; you should take up a position external to everything and everyone, drive off or grind down your appetites, live, according to a Hindu adage, with as few desires as a "solitary elephant.

Among all the great men who have philosophized about this remarkable effect, I am more astonished at Kepler than at any other. Despite his open and acute mind, and though he has at his fingertips the motions attributed to the earth, he nevertheless lent his ear and his assent to the moon's dominion over the waters, to occult properties, and to such puerilities.

Do not be guilty of possessing a library of learned books while lacking learning yourself.

When one considers the sublime disposition underlying the tmly universal educatiOn (of traditional India) ... then what IS or has been called religion in Europe seems to us to be scarcely deserving of that name. And one feels compelled to advise those who Wish to witness religion to travel to India for that purpose ....

He who is not satisfied with a little, is satisfied with nothing.

Civil government, so far as it is instituted for the security of property, is in reality instituted for the defence of the rich against the poor, or of those who have some property against those who have none at all.

Patriotism ruins history.

In the first place, the German is a branch of the Teutonic race. Of the latter it is sufficient to say here that its mission was to combine the social order established in ancient Europe with the true religion preserved in ancient Asia, and in this way to develop in and by itself a new and different age after the ancient world had perished.

Some teachers of mankind - as Plato... the first Christians, the orthodox Muslims, and the Buddhists - have gone so far as to repudiate art. ...[They consider it] so highly dangerous in its power to infect people against their wills, that mankind will lose far less by banishing all art than by tolerating each and every art. ...such people were wrong in repudiating all art, for they denied that which cannot be denied - one of the indispensable means of communication, without which mankind could not exist. ...Now there is only fear, lest we should be deprived of any pleasures art can afford, so any type of art is patronized. And I think the last error is much grosser than the first and that its consequences are far more harmful.

For we are mistaken when we look forward to death; the major portion of death has already passed. Whatever years be behind us are in death's hands.

What postulate do we implicitly admit? It is that the duration of two identical phenomena is the same; or... that the same causes take the same time to produce the same effects. ...Is it impossible that experiment may some day contradict our postulate?

When equality is treated not as a medicine or a safety-gadget, but as an ideal, we begin to breed that stunted and envious sort of mind which hates all superiority. That mind is the special disease of democracy, as cruelty and servility are the special diseases of privileged societies. It will kill us all if it grows unchecked. The man who cannot conceive a joyful and loyal obedience on the one hand, nor an unembarrassed and noble acceptance of that obedience on the other - the man who has never even wanted to kneel or to bow - is a prosaic barbarian. But it would be wicked folly to restore these old inequalities on the legal or external plane. Their proper place is elsewhere.

Newton, and 'proper scientific method' after him, conducted attention to 'continuous description' of experimental phenomena instead of to causes.

Now drown care in wine.

But the exceedingly foul deed of Onan, the basest of wretches, follows. Onan must have been a malicious and incorrigible scoundrel. This is a most disgraceful sin. It is far more atrocious than incest and adultery. We call it unchastity, yes a Sodomitic sin. For Onan goes in to her; that is, he lies with her and copulates, and when it comes to the point of insemination, spills the semen, lest the woman conceive. Surely at such a time the order of nature established by God in procreation should be followed. Accordingly, it was a most disgraceful crime to produce semen and excite the woman, and to frustrate her at that very moment.

Yes, there was an element of abstraction and unreality in misfortune. But when an abstraction starts to kill you, you have to get to work on it.

War is sweet to them that know it not.

Existentialism is nothing else but an attempt to draw the full conclusions from a consistently atheistic position. Its intention is not in the least that of plunging men into despair. And if by despair one means as the Christians do - any attitude of unbelief, the despair of the existentialists is something different. Existentialism is not atheist in the sense that it would exhaust itself in demonstrations of the non-existence of God. It declares, rather, that even if God existed that would make no difference from its point of view. Not that we believe God does exist, but we think that the real problem is not that of His existence; what man needs is to find himself again and to understand that nothing can save him from himself, not even a valid proof of the existence of God. In this sense existentialism is optimistic. It is a doctrine of action, and it is only by self-deception, by confining their own despair with ours that Christians can describe us as without hope.

Everything in the universe goes by indirection. There are no straight lines.

There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder (including it is true, some of the attempts to suppress them). This history is taught in schools, and some of the greatest criminals are extolled as heroes. 

Choose rather to be strong in soul than in body.

One cannot demand of a scholar that he show himself a scholar everywhere in society, but the whole tenor of his behavior must none the less betray the thinker, he must always be instructive, his way of judging a thing must even in the smallest matters be such that people can see what it will amount to when, quietly and self-collected, he puts this power to scholarly use.

It is by the Imperial Capital that contemporaries (and posterity, too) judge an Empire, and its magnificence impresses them mightily and leads them to judge the Emperor a great man and hero, even though it may all be based on robbery, and though the provinces of the Empire may be sunk in misery.

The task of power is to transform the always possible 'no' into a 'yes.'

After silence that which comes nearest to expressing the inexpressible is music.

The noble simplicity in the works of nature only too often originates in the noble shortsightedness of him who observes it.

In the deepest heart of all of us there is a corner in which the ultimate mystery of things works sadly.

Peace be with you. Receive my peace unto yourselves. Beware that no one lead you astray saying Lo here or lo there! For the Son of Man is within you. Follow after Him! Those who seek Him will find Him. Go then and preach the gospel of the Kingdom. Do not lay down any rules beyond what I appointed you, and do not give a law like the lawgiver lest you be constrained by it.

I pass, at length, to the third and perfectly absolute dominion, which we call democracy.

If God had looked into our minds he would not have been able to see there whom we were speaking of.

Faith which does not doubt is dead faith.

To disrespect the masses is moral; to honor them, lawful.
