Monsieur ... I do not believe in God; his existence has been disproved by Science. But in the concentration camp, I learned to believe in men.

We do not know whether Hitler is going to found a new Islam. (He is already on the way; he is like Mohammed. The emotion in Germany is Islamic; warlike and Islamic. They are all drunk with a wild god.)

The fact that life has no meaning is a reason to live - moreover, the only one.

The good of the people must be the great purpose of government. By the laws of nature and of reason, the governors are invested with power to that end. And the greatest good of the people is liberty. It is to the state what health is to the individual.

Ideas should be neutral. But man animates them with his passions and folly. Impure and turned into beliefs, they take on the appearance of reality. The passage from logic is consummated. Thus are born ideologies, doctrines, and bloody farce.

Cannot we understand how these men worshipped Canopus; became what we call Sabeans, worshipping the stars? Such is to me the secret of all forms of Paganism. Worship is transcendent wonder; wonder for which there is now no limit or measure; that is worship.

No man who has once heartily and wholly laughed can be altogether irreclaimably bad.

Yes perhaps, as the Sage says, "nothing worthy of proving can be proven, nor yet disproven"; but can we restrain that instinct which urges man to wish to know, and above all to wish to know the things which conduce to life, to eternal life? Eternal life, not eternal knowledge as the Alexandrian gnostic said. For living is one thing and knowing is another; and... perhaps there is an opposition between the two that we may say that everything vital is anti-rational, not merely irrational, and that everything rational is anti-vital. And this is the basis of the tragic sense of life.

I do not regard the late Carl Sagan as any kind of authority. On the contrary, as this book will show, I regard him in many ways as a dubious publicity seeker and careerist, more concerned to maintain his reputation as the brilliant and sceptical representative of hard-headed science than to look squarely and honestly at the facts.

We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

Happiness is the free play of the instincts, and so is youth.

A witty saying proves nothing.

This is approximately the way Christendom relates to the essentially Christian, the unconditioned. After seventeen, eighteen detours and running all around someone finally has his finite existence assured, and then we receive a sermon about Seek first the kingdom of God. Is this sobriety or is this intoxication?

Humans are prone to status quo bias. So let's do a thought-experiment. Imagine we stumble across an advanced civilisation that has abolished predation, disease, famine, and all the horrors of primitive Darwinian life. The descendants of archaic lifeforms flourish unmolested in their wildlife parks - free living, but not "wild". Should we urge scrapping their regime of compassionate stewardship of the living world - and a return to asphyxiation, disembowelling and being eaten alive? Or is a happy biosphere best conserved intact? Reply to "Should humans wipe out all carnivorous animals so the succeeding generations of herbivores can live in peace?"

Where there is politics or economics, there is no morality.

But where is the antidote for lucid despair, perfectly articulated, proud, and sure? All of us are miserable, but how many know it? The consciousness of misery is too serious a disease to figure in an arithmetic of agonies or in the catalogues of the Incurable. It belittles the prestige of hell, and converts the slaughterhouses of time into idyls. What sin have you committed to be born, what crime to exist? Your suffering like your fate is without motive. To suffer, truly to suffer, is to accept the invasion of ills without the excuse of causality, as a favor of demented nature, as a negative miracle. . .

For it was my master who taught me not only how very little I knew but also that any wisdom to which I might ever aspire could consist only in realizing more fully the infinity of my ignorance.

It is a familiar and significant saying that a problem well-put is half-solved.

History, if viewed as a repository for more than anecdote or chronology, could produce a decisive transformation in the image of science by which we are now possessed.

The might which kills outright is an elementary and coarse form of might. How much more varied in its devices; how much more astonishing in its effects is that other which does not kill; or which delays killing.

Saying is one thing and doing is another.

Impossible to accede to truth by opinions, for each opinion is only a mad perspective of reality.

At sunset of the third day, near the village of Igendja, we moved along an island set in the middle of the wide river. On a sandback to our left, four hippopotamuses and their young plodded along in our same direction. Just then, in my great tiredness and discouragement, the phrase "Reverence for Life" struck me like a flash. As far as I knew, it was a phrase I had never heard nor ever read. I realized at once that it carried within itself the solution to the problem that had been torturing me. Now I knew that a system of values which concerns itself only with our relationship to other people is incomplete and therefore lacking in power for good. Only by means of reverence for life can we establish a spiritual and humane relationship with both people and all living creatures within our reach. Only in this fashion can we avoid harming others, and, within the limits of our capacity, go to their aid whenever they need us.

Sex is no longer a serious taboo. Teenagers sometimes know more about it than adults.

If any one will piously and soberly consider the sermon which our Lord Jesus spoke on the mount, as we read it in the Gospel according to Matthew, I think that he will find in it, so far as regards the highest morals, a perfect standard of the Christian life: and this we do not rashly venture to promise, but gather it from the very words of the Lord Himself. For the sermon itself is brought to a close in such a way, that it is clear there are in it all the precepts which go to mould the life. He has sufficiently indicated, as I think, that these sayings which He uttered on the mount so perfectly guide the life of those who may be willing to live according to them, that they may justly be compared to one building upon a rock.

Égalité is an expression of envy. It means, in the real heart of every Republican, " No one shall be better off than I am;" and while this is preferred to good government, good government is impossible.

In television, images are projected at you. You are the screen. The images wrap around you. You are the vanishing point.

When a book and a head collide and a hollow sound is heard, must it always have come from the book?

A person can perhaps succeed in hiding his sins from the world, he can perhaps be foolishly happy that he succeeds, or yet, a little more honest, admit that it is a deplorable weakness and cowardliness that he does not have the courage to become open-but a person cannot hide his sins from himself.

The 'public' is a phantom, the phantom of an opinion supposed to exist in a vast number of persons who have no effective interrelation and though the opinion is not effectively present in the units. Such an opinion is spoken of as 'public opinion,' a fiction which is appealed to by individuals and by groups as supporting their special views. It is impalpable, illusory, transient; "'tis here, 'tis there, 'tis gone"; a nullity which can nevertheless for a moment endow the multitude with power to uplift or destroy.

Speed, it seems to me, provides the one genuinely modern pleasure.

The blazing evidence of immortality is our dissatisfaction with any other solution.

Asked where he came from, he said, "I am a citizen of the world."

Disobedience to authority is one of the most natural and healthy acts.

Understand me well. My appeal is to observation - observation that each of you must make for himself.

It is the good children, Madame, who make the most terrible revolutionaries. They say nothing, they do not hide under the table, they eat only one sweet at a time, but later on, they make Society pay dearly for it!

They are such fools that they seem to expect that, though the Republic is lost, their fish-ponds will be safe.

By what aberration has suicide, the only truly normal action, become the attribute of the flawed?

Religious beauty is superior to ideal beauty, since it is the ideal of the ideal.

Those alone are dear to Divinity who are hostile to injustice.

An individual who finds that he enjoys seeing others in positions of lesser liberty understands that he has no claim whatever to this enjoyment.

We are disposed, somewhat by culture and somewhat by nature, to solve our problems by violence, and even to enjoy doing so. And yet by now all of us must at least have suspected that our right to live, to be free, and to be at peace is not guaranteed by any act of violence. It can be guaranteed only by our willingness that all other persons should live, be free, and be at peace - and by our willingness to use or give our own lives to make that possible.

There are three lines of life which stand out prominently to view: the life of pleasure, the political life, and the life of reflection.

The seeds of heavenly bodies are deposited and cared for in the Milky Way, from which they emanate in swarms of comets that travel a ;long time and ordinarily gravitate towards various suns before becoming fixed in orbit.

The worker becomes all the poorer the more wealth he produces, the more his production increases in power and range. The worker becomes an ever cheaper commodity the more commodities he creates. With the increasing value of the world of things proceeds in direct proportion the devaluation of the world of men. Labour produces not only commodities; it produces itself and the worker as a commodity - and does so in the proportion in which it produces commodities generally.

We may well be ashamed to tell what things we have read or heard in our day. I do not know why my news should be so trivial, - considering what one's dreams and expectations are, why the developments should be so paltry. The news we hear, for the most part, is not news to our genius. It is the stalest repetition.
