A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.

By extensively studying all learning, and keeping himself under the restraint of the rules of propriety, one may thus likewise not err from what is right.

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

If A is success in life, then A = x + y + z. Work is x, play is y and z is keeping your mouth shut.

But what then is this confrontation below the language of reason? Where might this interrogation lead, following not reason in its horizontal becoming, but seeking to retrace in time this constant verticality, which, the length of Western culture, confronts it with what it is not, measuring it with its own extravagance?

There is no chastisement that does not purify; there is no disorder that ETERNAL LOVE does not turn against the principle of evil.

How many of us are able to distinguish between the odors of noon and midnight, or of winter and summer, or of a windy spell and a still one? If man is so generally less happy in the cities than in the country, it is because all these variations and nuances of sight and smell and sound are less clearly marked and lost in the general monotony of gray walls and cement pavements.

For those who live inside a myth, it seems a self-evident fact. Human progress is a fact of this kind. If you accept it you have a place in the grand march of humanity. Humankind is, of course, not marching anywhere. 'Humanity' is a fiction composed from billions of individuals for each of whom life is singular and final. But the myth of progress is extremely potent. When it loses its power those who have lived by it are - as Conrad put it, describing Kayerts and Carlier - 'like those lifelong prisoners who, liberated after many years, do not know what use to make of their freedoms'. When faith in the future is taken from them, so is the image they have of themselves. If they then opt for death, it is because without that faith they can no longer make sense of living.

Lastly, we must also know what Baptism signifies, and why God has ordained just such external sign and ceremony for the Sacrament by which we are first received into the Christian Church. But the act or ceremony is this, that we are sunk under the water, which passes over us, and afterwards are drawn out again. These two parts, to be sunk under the water and drawn out again, signify the power and operation of Baptism, which is nothing else than putting to death the old Adam, and after that the resurrection of the new man, both of which must take place in us all our lives, so that a truly Christian life is nothing else than a daily baptism, once begun and ever to be continued.

There is a contrast of primary significance between Augustine and Pelagius. The former crushes everything in order to rebuild it again. The other addresses himself to man as he is. The first system, therefore, in respect to Christianity, falls into three stages: creation – the fall and a consequent condition of death and impotence; a new creation - whereby man is placed in a position where he can choose; and then, if he chooses - Christianity. The other system addresses itself to man as he is (Christianity fits into the world). From this is seen the significance of the theory of inspiration for the first system; from this also is seen the relationship between the synergistic and the semipelagian conflict. It is the same question, only that the syngeristic struggle has its presupposition in the new creation of the Augustinian system.

It is the privilege of true genius, and certainly of the genius that opens a new road, to make without punishment great mistakes.

One can only become a philosopher, but not be one. As one believes he is a philosopher, he stops being one.

If one awakens in men the idea of freedom then the free men will incessantly go on to free themselves; if on the contrary, one only educates them, then they will at all times accommodate themselves to circumstance in the most highly educated and elegant manner and degenerate into subservient cringing souls.

We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

"You will have less money." Yes, and less trouble. "Less influence." Yes, and less envy.

The savage recognizes life only in himself and his personal desires. His interest in life is concentrated on himself alone. The highest happiness for him is the fullest satisfaction of his desires. The motive power of his life is personal enjoyment. His religion consists in propitiating his deity and in worshiping his gods, whom he imagines as persons living only for their personal aims.

Nonviolence is perhaps best described as a practice of resistance that becomes possible, if not mandatory, precisely at the moment when doing violence seems most justified and obvious. In this way, it can be understood as a practice that not only stops a violent act, or a violent process, but requires a form of sustained action, sometimes aggressively pursued. So, one suggestion I will make is that we can think of nonviolence not simply as the absence of violence, or as the act of refraining from committing violence, but as a sustained commitment, even a way of rerouting aggression for the purposes of affirming ideals of equality and freedom.

Perception and knowledge could never be the same.

The deeper we look into nature, the more we recognize that it is full of life, and the more profoundly we know that all life is a secret and that we are united with all life that is in nature. Man can no longer live for himself alone. We realize that all life is valuable, and that we are united to all this life. From this knowledge comes our spiritual relationship to the universe.

My sympathies are, of course, with the Government side, especially the Anarchists; for Anarchism seems to me more likely to lead to desirable social change than highly centralized, dictatorial Communism.

When anything is present to the mind, what is the very first and simplest character to be noted in it, in every case, no matter how little elevated the object may be? Certainly, it is its presentness.

The prospects of revolution seem therefore quite restricted. For can a revolution avoid war? It is, however, on this feeble chance that we must stake everything or abandon all hope. An advanced country will not encounter, in the case of revolution, the difficulties which in backward Russia served as a base for the barbarous regime of Stalin. But a war of any scope will give rise to others as formidable.

And why be scandalized by the infallibility of a man, of the Pope? What difference does it make whether it be a book that is infallible - the Bible, or a society of men - the Church, or a single man? Does it make any essential change in the rational difficulty? And since the infallibility of a book or of a society of men is not more rational than that of a single man, this supreme offense to the eyes of reason has to be postulated.

In ancient Europe, Stoics asserted that a slave could be freer than a master who suffers from self-division. In China, Daoists imagined a type of sage who responded to the flow of events without weighing alternatives. Disciples of monotheistic faiths have believed something similar: freedom, they say, is obeying God's will. What those who follow these traditions want most is not any kind of freedom of choice. Instead, what they long for is freedom from choice.

But men must know that in this theater of man's life it is reserved only for God and angels to be lookers on.

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.

Gratitude looks to the past and love to the present; fear, avarice, lust, and ambition look ahead.

A character is a completely fashioned will.

What is it that distinguishes man from animals? It is not his upright posture. That was present in the apes long before the brain began to develop. Nor is it the use of tools. It is something altogether new, a previously unknown quality: self-awareness. Animals, too, have awareness. They are aware of objects; they know this is one thing and that another. But when the human being as such was born he had a new and different consciousness, a consciousness of himself; he knew that he existed and that he was something different, something apart from nature, apart from other people, too. He experienced himself. He was aware that he thought and felt. As far as we know, there is nothing analogous to this anywhere in the animal kingdom. That is the specific quality that makes human beings human.

The freest importation of salt provisions, in the same manner, could have as little effect upon the interest of the graziers of Great Britain as that of live cattle. Salt provisions are not only a very bulky commodity, but when compared with fresh meat, they are a commodity both of worse quality, and as they cost more labour and expence, of higher price. They could never, therefore, come into competition with the fresh meat, though they might with the salt provisions of the country.

Attention is the rarest and purest form of generosity.

People talk sometimes of bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel.

There is more of good nature than of good sense at the bottom of most marriages.

The mind celebrates a little triumph whenever it can formulate a truth, however unwelcome to the flesh, or discover an actual force, however unfavourable to given interests.

Wherever an altar is found, there civilization exists.

Too many French scholars were the principal authors of the Revolution, too many approved and gave their support so long as the Revolution, like Tarquinius' sceptre, struck down only the tallest heads. Like so many others, they said, It is impossible to make a great revolution without incurring misfortunes. But when a philosopher justifies evil by the end in view, when he says in his heart, Let there be a hundred thousand murders, provided we are free, and Providence replies, I accept your offer, but you must be included in the number, where is the injustice?

Indeed, even this last moment will be recognized like the rest, at least, be just beginning to be so.

A man possessed of splendid talents, which he often abused, and of a sound judgment, the admonitions of which he often neglected; a man who succeeded only in an inferior department of his art, but who in that department succeeded pre-eminently.

We shall have to share out the fruits of technology among the whole of mankind. The notion that the direct and immediate producers of the fruits of technology have a proprietary right to these fruits will have to be forgotten. After all, who is the producer? Man is a social animal, and the immediate producer has been helped to produce by the whole structure of society, beginning with his own education.

All hopes and despairs vanish in the voracious, funneling whirlwind of God. God laughs, wails, kills, sets us on fire, and then leaves us in the middle of the way, charred embers. And I rejoice to feel between my temples, in the flicker of an eyelid, the beginning and the end of the world. I condense into a lightning moment the seeding, sprouting, blossoming, fructifying, and the disappearance of every tree, animal, man, star, and god. All Earth is a seed planted in the coils of my mind. Whatever struggles for numberless years to unfold and fructify in the dark womb of matter bursts in my head like a small and silent lightning flash. Ah! let us gaze intently on this lightning flash, let us hold it for a moment, let us arrange it into human speech. Let us transfix this momentary eternity which encloses everything, past and future, but without losing in the immobility of language any of its gigantic erotic whirling.

I have cast fire upon the world, and see, I am guarding it until it blazes.

Every man is fully satisfied that there is such a thing as truth, or he would not ask any question.

I do feel that evolution is being controlled by some sort of divine engineer. I can't help thinking that. And this engineer knows exactly what he or she is doing and why, and where evolution is headed. That's why we've got giraffes and hippopotami and the clap.
