On reaching Athens he fell in with Antisthenes. Being repulsed by him, because he never welcomed pupils, by sheer persistence Diogenes wore him out. Once when he stretched out his staff against him, the pupil offered his head with the words, "Strike, for you will find no wood hard enough to keep me away from you, so long as I think you've something to say."

People understand the meaning of eating lies in the nourishment of the body only when they cease to consider that the object of that activity is pleasure. ...People understand the meaning of art only when they cease to consider that the aim of that activity is beauty, i.e., pleasure.

If I compare arithmetic with a tree that unfolds upward into a multitude of techniques and theorems while its root drives into the depths, then it seems to me that the impetus of the root.

As there were black swans, though civilized people had existed for three thousand years on the earth without meeting with them...The uniform experience, therefore, of the inhabitants of the known world, agreeing in a common result, without one known instance of deviation from that result, is not always sufficient to establish a general conclusion.

In former times the chief method of justifying the use of violence and thereby infringing the law of love was by claiming a divine right for the rulers: the Tsars, Sultans, Rajahs, Shahs, and other heads of states. But the longer humanity lived the weaker grew the belief in this peculiar, God-given right of the ruler. That belief withered in the same way and almost simultaneously in the Christian and the Brahman world, as well as in Buddhist and Confucian spheres, and in recent times it has so faded away as to prevail no longer against man's reasonable understanding and the true religious feeling. People saw more and more clearly, and now the majority see quite clearly, the senselessness and immorality of subordinating their wills to those of other people just like themselves, when they are bidden to do what is contrary not only to their interests but also to their moral sense.

Dear youths, I warn you cherish peace divine, And in your hearts lay deep these words of mine.

The stupider one is, the closer one is to reality. The stupider one is, the clearer one is. Stupidity is brief and artless, while intelligence wriggles and hides itself. Intelligence is a knave, but stupidity is honest and straightforward.

This mortal Don Quixote died and descended into hell, which he entered lance on rest, and freed all the condemned, as he freed the galley slaves, and he shut the gates of hell, and tore down the scroll that Dante saw there and replaced it by one on which was written "Long live hope!" and escorted by those whom he had freed, and they laughing at him, he went to heaven. And God laughed paternally at him, and this divine laughter filled his soul with eternal happiness.

Those animals which are incapable of making binding agreements with one another not to inflict nor suffer harm are without either justice or injustice; and likewise for those peoples who either could not or would not form binding agreements not to inflict nor suffer harm.

Science fiction may be defined as that branch of literature which deals with the response of human beings to advances in science and technology. Actual change in science and technology, occurring quickly enough and striking deeply enough to affect a human being in the course of his normal lifetime, is a phenomenon peculiar to the world only since the Industrial Revolution ... The first well-known writer who responded to this new factor in human affairs by dealing regularly with science fiction, by studying the effect of additional scientific advance upon mankind ... was Jules Verne. In the English language, the early master was H. G. Wells. Between them, they laid the foundation for every theme upon which science fiction writers have been ringing variations ever since.

Men are qualified for civil liberty in exact proportion to their disposition to put moral chains upon their own appetites, - in proportion as their love to justice is above their rapacity, - in proportion as their soundness and sobriety of understanding is above their vanity and presumption, - in proportion as they are more disposed to listen to the counsels of the wise and good, in preference to the flattery of knaves. Society cannot exist, unless a controlling power upon will and appetite be placed somewhere; and the less of it there is within, the more there must be without. It is ordained in the eternal constitution of things, that men of intemperate minds cannot be free. Their passions forge their fetters.

Democracies owe their existence to national loyalties - the loyalties that are supposedly shared by government and opposition, by all political parties, and by the electorate as a whole. Wherever the experience of nationality is weak or non-existent, democracy has failed to take root. For without national loyalty, opposition is a threat to government, and political disagreements create no common ground.

There is but one Temple in the World; and that is the Body of Man. Nothing is holier than this high form. Bending before men is a reverence done to this Revelation in the Flesh. We touch Heaven, when we lay our hand on a human body. Variant translation: There is but one temple in the Universe and that is the Body of Man.

Imagination, which is the social sense, animates the inanimate and anthropomorphizes everything; it humanizes everything and even makes everything identical with man. And the work of man is to supernaturalize Nature - that is to say, to make it divine by making it human, to help it to become conscious of itself, in short. The action of reason, on the other hand, is to mechanize or materialize.

I believe that the fundamental alternative for man is the choice between "life" and "death"; between creativity and destructive violence; between reality and illusions; between objectivity and intolerance; between brotherhood-independence and dominance-submission.

The voice in my soul in which I will have faith, and for the sake of which I have faith in all else, does not merely command me generally to act, but in every particular situation it declares what I shall do and what leave undone; it accompanies me through every event of my life, and it is impossible for me to contend against it. To listen to it and obey it honestly and impartially, without fear or equivocation, is the business of my existence. My life is no longer an empty I play without truth or significance. It is appointed that what I conscience ordains me shall be done, and for this purpose am I here. I have understanding to know, and power to execute it. By conscience alone comes truth and reality into my representations.

Every one is familiar with the phenomenon of feeling more or less alive on different days. Every one knows on any given day that there are energies slumbering in him which the incitements of that day do not call forth, but which he might display if these were greater. Most of us feel as if we lived habitually with a sort of cloud weighing on us, below our highest notch of clearness in discernment, sureness in reasoning, or firmness in deciding. Compared with what we ought to be, we are only half-awake. Our fires are damped, our drafts are checked. We are making use of only a small part of our possible mental and physical resources.

The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. WORKING MEN OF ALL COUNTRIES, UNITE!

I do like clarity and exact thinking and I believe that very important to mankind because when you allow yourself to think inexactly your prejudices, your bias, your self interest comes in in ways you don't notice and you do bad things without knowing that you are doing them: self deception is very easy. So that I do think clear thinking immensely important.

I can assure you that there is the greatest practical benefit in making a few failures early in life. You learn that which is of inestimable importance - that there are a great many people in the world who are just as clever as you are. You learn to put your trust, by and by, in an economy and frugality of the exercise of your powers, both moral and intellectual; and you very soon find out, if you have not found it out before, that patience and tenacity of purpose are worth more than twice their weight of cleverness.

Survive in such a way that you avoid limiting others who are also trying to survive. We all live in limited systems. This is the core of ethics.

Pardon one offence and you encourage the commission of many.

Impenetrable in their dissimulation, cruel in their vengeance, tenacious in their purposes, unscrupulous as to their methods, animated by profound and hidden hatred for the tyranny of man - it is as though there exists among them an ever-present conspiracy toward domination, a sort of alliance like that subsisting among the priests of every country.

Holding fast to these things, you will know the worlds of gods and mortals which permeates and governs everything. And you will know, as is right, nature similar in all respects, so that you will neither entertain unreasonable hopes nor be neglectful of anything.

Upstart greatness is everywhere less respected than ancient greatness.

Man ought to be content, it is said; but with what?

From the poetry of Lord Byron they drew a system of ethics, compounded of misanthropy and voluptuousness, a system in which the two great commandments were, to hate your neighbour, and to love your neighbour's wife.

Thought must never submit, neither to a dogma, nor to a party, nor to a passion, nor to an interest, nor to a preconceived idea, nor to whatever it may be, save to the facts themselves, because, for thought, submission would mean ceasing to be.

In classroom settings I have often listened to groups of students tell me that racism really no longer shapes the contours of our lives, that there is no such thing as racial difference, that "we are all just people." Then a few minutes later I give them an exercise. I ask if they were about to die and could choose to come back as a white male, a white female, a black female, or a black male, which identity would they choose. Each time I do this exercise, most individuals, irrespective of gender or race invariably choose whiteness, and most often male whiteness. Black females are the least chosen. When I ask students to explain their choice they proceed to do a sophisticated analysis of privilege based on race (with perspectives that take gender and class into consideration).

Shut out the evil love of the world, that you may be filled with the love of God. You are a vessel that was already full: you must pour away what you have, that you may take in what you have not.

The foremost, or indeed the sole condition which is required in order to succeed in centralizing the supreme power in a democratic community, is to love equality, or to get men to believe you love it. Thus the science of despotism, which was once so complex, is simplified, and reduced as it were to a single principle.

We are told that Christ was killed for us, that His death has washed out our sins, and that by dying He has disabled death itself. That is the formula. That is Christianity. That is what has to be believed. Any theories we build up as to how Christ's death did all this are, in my view, quite secondary: mere plans or diagrams to be left alone if they do not help us, and, if they do help us, not to be confused with the thing itself.

Every stage of education begins with childhood. That is why the most educated person on earth so much resembles a child.

Words of the jargon sound as if they said something higher than what they mean.

Both of us victims of the same twentieth-century plague. Not the Black Death, this time; the Grey Life.

Such arguments ill become us, since the time of reformation came, under Gospel light. All distinctions of nations, and privileges of one above others, are ceased; Christians are taught to account all men their neighbours; and love their neighbours as themselves; and do to all men as they would be done by; to do good to all men; and Man-stealing is ranked with enormous crimes. Is the barbarous enslaving our inoffensive neighbours, and treating them like wild beasts subdued by force, reconcilable with all these Divine precepts? Is this doing to them as we would desire they should do to us? If they could carry off and enslave some thousands of us, would we think it just?-One would almost wish they could for once; it might convince more than Reason, or the Bible.

The baby, assailed by eyes, ears, nose, skin, and entrails at once, feels it all as one great blooming, buzzing confusion; and to the very end of life, our location of all things in one space is due to the fact that the original extents or bignesses of all the sensations which came to our notice at once, coalesced together into one and the same space.

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.

Non-operational ideas are non-behavioral and subversive. The movement of thought is stopped at barriers which appear as the limits of Reason itself.

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.

The one intelligible theory of the universe is that of objective idealism, that matter is effete mind, inveterate habits becoming physical laws. But before this can be accepted it must show itself capable of explaining the tridimensionality of space, the laws of motion, and the general characteristics of the universe, with mathematical clearness and precision ; for no less should be demanded of every Philosophy.

Every technology contrived and "outered" by man has the power to numb human awareness during the period of its first interiorization.

Know, first, who you are, and then adorn yourself accordingly.

The capacity of the human mind for formulating and solving complex problems is very small compared with the size of the problems whose solution is required for objectively rational behavior in the real world-or even for a reasonable approximation to such objective rationality.

An increase in the productivity of labour means nothing more than that the same capital creates the same value with less labour, or that less labour creates the same product with more capital.

Classics which at home are drowsily read have a strange charm in a country inn, or in the transom of a merchant brig.

The deepest and most organic death is death in solitude, when even light becomes a principle of death. In such moments you will be severed from life, from love, smiles, friends and even from death. And you will ask yourself if there is anything besides the nothingness of the world and your own nothingness.
