In the most secret chamber of the spirit of him who believes himself convinced that death puts an end to his personal consciousness, his memory, for ever, and all unknown to him perhaps, there lurks a shadow, a vague shadow, a shadow of uncertainty, and while he says within himself, "Well, let us live this life that passes away, for there is no other!" the silence of this secret chamber speaks to him and murmurs, "Who knows!... " These voices are like the humming of a mosquito when the south-west wind roars through the trees in the wood; we cannot distinguish this faint humming, yet nevertheless, merged in the clamor of the storm, it reaches the ear.

If one only wished to be Sad, this could be horrible for the rest of civilisation; but we wish to be happier than other people, and this is always difficult, for we believe others to be happier than they are.

What renders man an imaginative and moral being is that in society he gives new aims to his life which could not have existed in solitude: the aims of friendship, religion, science, and art.

Good roads, canals, and navigable rivers, by diminishing the expence of carriage, put the remote parts of the country more nearly upon a level with those of the neighbourhood of the town. They are upon that the greatest of all improvements.

Growth is slow but collapse is rapid.

This remark provides the key to the problem, how much truth there is in solipsism. For what the solipsist means is quite correct; only it cannot be said, but makes itself manifest. The world is my world: this is manifest in the fact that the limits of language (of that language which alone I understand) mean the limits of my world.

Man... whatever the origin of his soul, if it is pure, noble, and lofty, it is a beautiful soul which dignifies the man endowed with it.

But if one Subject giveth Counsell to another, to do anything contrary to the Lawes, whether that Counsell proceed from evil intention, or from ignorance onely, it is punishable by the Common-wealth; because ignorance of the Law, is no good excuse, where every man is bound to take notice of the Lawes to which he is subject.

A magical portal opened inside my mind and conducted me into an astonishing world. ... Before this moment I had divined but had never known with such positiveness that the world is extremely large and that suffering and toil are the companions and fellow warriors not only of Cretan, but of every man. ... that by means of poetry all this suffering and effort could be transformed into dream; no matter how much of the ephemeral existed, poetry could immortalize it by turning it into song.

Everyone sits in the prison of his own ideas; he must burst it open, and that in his youth, and so try to test his ideas on reality.

Always remember that it is impossible to speak in such a way that you cannot be misunderstood: there will always be some who misunderstand you.

All mortals are equal; it is not their birth,But virtue itself that makes the difference.

This perversion of the ethical values soon crystallized into the all-dominating slogan of the Communist Party: THE END JUSTIFIES ALL MEANS. Similarly in the past the Inquisition and the Jesuits adopted this motto and subordinated to it all morality. It avenged itself upon the Jesuits as it did upon the Russian Revolution. In the wake of this slogan followed lying, deceit, hypocrisy and treachery, murder, open and secret. It should be of utmost interest to students of social psychology that two movements as widely separated in time and ideas as Jesuitism and Bolshevism reached exactly similar results in the evolution of the principle that the end justifies all means. The historic parallel, almost entirely ignored so far, contains a most important lesson for all coming revolutions and for the whole future of mankind.

There is a sort of gratification in doing good which makes us rejoice in ourselves.

There is no social entity with a good that undergoes some sacrifice for its own good. There are only individual people, different individual people, with their own individual lives. Using one of these people for the benefit of others, uses him and benefits the others. Nothing more.

The law of simplicity and naïveté applies to all fine art, for it is compatible with what is most sublime. True brevity of expression consists in a man only saying what is worth saying, while avoiding all diffuse explanations of things which every one can think out for himself; that is, it consists in his correctly distinguishing between what is necessary and what is superfluous. On the other hand, one should never sacrifice clearness, to say nothing of grammar, for the sake of being brief. To impoverish the expression of a thought, or to obscure or spoil the meaning of a period for the sake of using fewer words shows a lamentable want of judgment.

Subjective reason ... is inclined to abandon the fight with religion by setting up two different brackets, one for science and philosophy, and one for institutionalized mythology, thus recognizing both of them. For the philosophy of objective reason there is no such way out. Since it hold to the concept of objective truth, it must take a positive or a negative stand with regard to the content of established religion.

What I will be remembered for are the Foundation Trilogy and the Three Laws of Robotics. What I want to be remembered for is no one book, or no dozen books. Any single thing I have written can be paralleled or even surpassed by something someone else has done. However, my total corpus for quantity, quality and variety can be duplicated by no one else. That is what I want to be remembered for.

When power is separated from any communicative context, it becomes naked violence.

Life is possible only by the deficiencies of our imagination and memory.

The happiness of men consists in life. And life is in labor.

People often say to me, You don't know what a wife and mother feels. No, I say, I don't and I'm very glad I don't. And they don't know what I feel. ... I am sick with indignation at what wives and mothers will do of the most egregious selfishness. And people call it all maternal or conjugal affection, and think it pretty to say so. No, no, let each person tell the truth from his own experience.

There is no moral precept that does not have something inconvenient about it.

The cheapest sort of pride is national pride; for if a man is proud of his own nation, it argues that he has no qualities of his own of which he can be proud; otherwise he would not have recourse to those which he shares with so many millions of his fellowmen. The man who is endowed with important personal qualities will be only too ready to see clearly in what respects his own nation falls short, since their failings will be constantly before his eyes. But every miserable fool who has nothing at all of which he can be proud adopts, as a last resource, pride in the nation to which he belongs; he is ready and glad to defend all its faults and follies tooth and nail, thus reimbursing himself for his own inferiority.

It has always been the task of formal education to set up behavior which would prove useful or enjoyable later in a student's life.

Since therefore, as well those degrees of heat that are not painful, as those that are, can exist in a thinking substance; may we not conclude that external bodies are absolutely incapable of any degree of heat whatsoever?

When the empirical investigator glories in his refusal to go beyond the specialized observation dictated by the traditions of his discipline, be they ever so inclusive, he is making a virtue out of a defense mechanism which insures him against questioning his presuppositions.

Suffering is a spiritual thing. It is the most immediate revelation of consciousness, and it may be that our body was given us simply in order that suffering might be enabled to manifest itself. A man who had never known suffering, either in greater or less degree, would scarcely possess consciousness of himself. The child first cries at birth when the air, entering into his lungs and limiting him, seems to say to him: You have to breathe me in order to live!

Tell me how you want to die, and I'll tell you who you are.

The best and greatest winning is a true friend; and the greatest loss is the loss of time.

Self-trust is the first secret of success.

My opinion concerning God differs widely from that which is ordinarily defended by modern Christians. For I hold that God is of all things the cause immanent, as the phrase is, not transient. I say that all things are in God and move in God, thus agreeing with Paul, and, perhaps, with all the ancient philosophers, though the phraseology may be different ; I will even venture to affirm that I agree with all the ancient Hebrews, in so far as one may judge from their traditions, though these are in many ways corrupted. The supposition of some, that I endeavour to prove in the Tractatus Theologico-Politicus the unity of God and Nature (meaning by the latter a certain mass or corporeal matter), is wholly erroneous. As regards miracles, I am of opinion that the revelation of God can only be established by the wisdom of the doctrine, not by miracles, or in other words by ignorance.

I entered the Communist Party because its cause was just and I will leave it when it ceases to be just.

The spirit of Poesy is the morning light, which makes the Statue of Memnon sound.

Ethics is in origin the art of recommending to others the sacrifices required for co-operation with oneself.

All government - indeed, every human benefit and enjoyment, every virtue and every prudent act - is founded on compromise and barter.

For what avail the plough or sail, Or land or life, if freedom fail?

Things that have a common quality ever quickly seek their kind.

Many who have not learned wisdom live wisely, and many who do the basest deeds can make most learned speeches.

As long as one does not call his own position into question but regards it as absolute, while interpreting his opponents' ideas as a mere function of the social positions they occupy, the decisive step forward has not yet been taken.

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?"

The object of all true Philosophy is to frame a system which shall comprehend human life under every aspect, social as well as individual. It embraces, therefore, the three kinds of phenomena of which our life consists, Thoughts, Feelings, and Actions.

... it may be hoped that the white population of the world will soon cease to increase. The Asiatic races will be longer, and the negroes still longer, before their birth rate falls sufficiently to make their numbers stable without help of war and pestilence. But it is to be hoped that the religious prejudices which have hitherto hampered the spread of birth control will die out, and that ... the whole world will learn not to be unduly prolific. Until that happens, the benefits aimed at by socialism can only be partially realized, and the less prolific races will have to defend themselves against the more prolific by methods which are disgusting even if they are necessary.

Reality and history, however, are not dialectical, and no idealist rhetorical gymnastics can make them conform to the dialect.
