Rationality requires a complete knowledge and anticipation of the consequences that will follow on each choice. In fact, knowledge of consequences is always fragmentary.

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

The heroic cannot be the common, nor can the common be heroic.

Law could never, by determining exactly what is noblest and must just for one and all, enjoin upon them that which is best; for the differences of men and of actions and the fact that nothing, I may say, in human life is ever at rest, forbid any science whatsoever to promulgate any simple rule for everything and for all time. So, that which is persistently simple is inapplicable to things which are never simple.

We have two ears and one mouth, so we should listen more than we say.

An organised system of machines, to which motion is communicated by the transmitting mechanism from a central automation, is the most developed form of production by machinery.

Time! Time! Time! - we must not impugn the Scripture Chronology, but we must interpret it in accordance with whatever shall appear on fair enquiry to be the truth for there cannot be two truths. And really there is scope enough: for the lives of the Patriarchs may as reasonably be extended to 5000 or 50000 years apiece as the days of Creation to as many thousand millions of years.

If I could put my hand on the north star, would it be as beautiful? The sea is lovely, but when we bathe in it, the beauty forsakes all the near water. For the imagination and senses cannot be gratified at the same time.

... the only contestant who can confidently enter the lists is the man who has seen his own blood, who has felt his teeth rattle beneath his opponent's fist, who has been tripped and felt the full force of his adversary's charge, who has been downed in body but not in spirit, one who, as often as he falls, rises again with greater defiance than ever.

The death of dogma is the birth of morality.

The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach. A man is ethical only when life, as such, is sacred to him, and that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. Only the universal ethic of the feeling of responsibility in an ever-widening sphere for all that lives - only that ethic can be founded in thought. ... The ethic of Reverence for Life, therefore, comprehends within itself everything that can be described as love, devotion, and sympathy whether in suffering, joy, or effort.

The population of the US is nearly 300 million, including many of the best educated, most talented, most resourceful, humane people on earth. By almost any measure of civilised attainment, from Nobel prize-counts on down, the US leads the world by miles. You would think that a country with such resources, and such a field of talent, would be able to elect a leader of the highest quality. Yet, what has happened? At the end of all the primaries and party caucuses, the speeches and the televised debates, after a year or more of non-stop electioneering bustle, who, out of that entire population of 300 million, emerges at the top of the heap? George Bush.

Don't hold yourselves cheap, seeing that the creator of all things and of you estimates your value so high, so dear, that he pours out for you every day the most precious blood of his only-begotten Son.

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.)

America is like a large, friendly dog in a very small room. Every time it wags its tail, it knocks over a chair!

The case of mere titles is so absurd that it would deserve to be treated only with ridicule were t not for the serious mischief they impose on mankind. The feudal system was a ferocious monster, devouring, where it came, all that the friend of humanity regards with attachment and love. The system of titles appears under a different form. The monster is at length destroyed, and they who followed in his train, and fattened upon the carcasses of those he slew, have stuffed his skin, and, b exhibiting it, hope still to terrify mankind into patient and pusillanimity.

By a clock we understand anything characterized by a phenomenon passing periodically through identical phases so that we must assume, by the principle of sufficient reason, that all that happens in a given period is identical with all that happens in an arbitrary period.

Either everything is illusion, nature as well as revelation, or experience alone can explain faith.

See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down.

Only a man who is at one with the world can be at one with himself.

As a way of maintaining relative intellectual independence, having the attitude of an amateur instead of a professional is a better course.

It is a thorny undertaking, and more so than it seems, to follow a movement so wandering as that of our mind, to penetrate the opaque depths of its innermost folds, to pick out and immobilize the innumerable flutterings that agitate it.

Once again, I experienced that overwhelming joy in the universe that I had felt in London outside the V and A. But this time, my consciousness of the world seemed larger, more complex. It was the mystic's sensation of oneness, of everything blending into everything else. Everything I looked at reminded me of something else, which also became present to my consciousness, as if I were simultaneously seeing a million worlds and smelling a million scents and hearing a million sounds-- not mixed up, but each separate and clear. I was overwhelmed with a sense of my smallness in the face of this vast, beautiful, objective universe, this universe whose chief miracle is that it exists, as well as myself. It is no dream, but a great garden in which life is trying to obtain a foothold. I experienced a desire to burst into tears of gratitude; then I controlled it, and the feeling subsided into a calm sense of immense, infinite beauty.

Whenever I have read any part of the Vedas, I have felt that some unearthly and unknown light illuminated me. In the great teaching of the Vedas, there is no touch of sectarianism. It is of all ages, climes and nationalities and is the royal road for the attainment of the Great Knowledge. When I am at it, I feel that I am under the spangled heavens of a summer night.

Reading is merely a surrogate for thinking for yourself; it means letting someone else direct your thoughts. Many books, moreover, serve merely to show how many ways there are of being wrong, and how far astray you yourself would go if you followed their guidance. You should read only when your own thoughts dry up, which will of course happen frequently enough even to the best heads; but to banish your own thoughts so as to take up a book is a sin against the holy ghost; it is like deserting untrammeled nature to look at a herbarium or engravings of landscapes.

A general definition of civilization: a civilized society is exhibiting the five qualities of truth, beauty, adventure, art, peace.

Justice is what love looks like in public.

For my part for one, though I make no doubt of preferring the antient Course, or almost any other to this vile chimera, and sick mans dream of Government yet I could not actively, or with a good heart, and clear conscience, go to the establishment of a monarchical despotism in the place of this system of Anarchy.

I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. I am the good shepherd: the good shepherd giveth his life for the sheep.

Any reductionist program has to be based on an analysis of what is to be reduced. If the analysis leaves something out, the problem will be falsely posed.

What potent blood hath modest May!

The essence of the good is a certain kind of moral purpose, and that of the evil is a certain kind of moral purpose.

Those hypotheses do not a little hinder the progress of Humane knowledge, that introduce Morals and Politicks into the Explications of Corporeal Nature, where all things are indeed transacted according to Laws Mechanical.

To eat is to appropriate by destruction.

The truth is a trap: you can not get it without it getting you; you cannot get the truth by capturing it, only by its capturing you.

Indeed, the drunken man while in that condition does not know the definition of drunkenness nor the scientific account of it; he has not the very least scientific knowledge of it. The sober man, on the other hand, knows the definition of drunkenness and its basis, yet he is not drunk in the very least. Again the doctor, when he is himself ill, knows the definition and causes of health and the remedies which restore it, and yet is lacking in health. Similarly there is a difference between knowing the true nature and causes and conditions of the ascetic life and actually leading such a life and forsaking the world.

It must have been in his teens, perhaps rather early, that he and his elder brother John, with William Bell (afterwards of Wylie Hill, and a noted drover) and his brother, all met in the kiln at Eelief to play cards. The corn was dried then at home. There was a fire, therefore, aud perhaps it was both heat and light. The boys had played, perhaps, often enough for trifling stakes, and always parted in good humor. One night they came to some disagreement. My father spoke out what was in him about the folly, the sinfulness, of quarreling over a perhaps sinful amusement. The earnest mind persuaded other minds. They threw the cards into the fire, and (I think the younger Bell told my brother James) no one of the four ever touched a card again through life. My father certainly never hinted at such a game since I knew him. I cannot remember that I, at that age, had any such force of belief. Which of us can?

All systems of morality are based on the idea that an action has consequences that legitimize or cancel it. A mind imbued with the absurd merely judges that those consequences must be considered calmly. It is ready to pay up. In other words, there may be responsible persons, but there are no guilty ones, in its opinion. At very most, such a mind will consent to use past experience as a basis for its future actions.

The true line is not between "hard" natural science and "soft" social sciences, but between precise science limited to highly abstract and simple phenomena in the laboratory and inexact science and technology dealing with complex problems in the real world.

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.

The coming of Buddhism to the West may well prove to be the most important event of the Twentieth Century.

The inherent contradiction of human life has now reached an extreme degree of tension: on the one side there is the consciousness of the beneficence of the law of love, and on the other the existing order of life which has for centuries occasioned an empty, anxious, restless, and troubled mode of life, conflicting as it does with the law of love and built on the use of violence. This contradiction must be faced, and the solution will evidently not be favourable to the outlived law of violence, but to the truth which has dwelt in the hearts of men from remote antiquity: the truth that the law of love is in accord with the nature of man. But men can only recognize this truth to its full extent when they have completely freed themselves from all religious and scientific superstitions and from all the consequent misrepresentations and sophistical distortions by which its recognition has been hindered for centuries.

All religions so far have been the expression of historical stages of development of individual peoples or groups of peoples. But communism is the stage of historical development which makes all existing religions superfluous and brings about their disappearance.

State and government are the social apparatus of violent coercion and repression. Such an apparatus, the police power, is indispensable in order to prevent anti-social individuals and bands from destroying social co-operation. Violent prevention and suppression of anti-social activities benefit the whole of society and each of its members. But violence and oppression are none the less evils and corrupt those in charge of their application. It is necessary to restrict the power of those in office lest they become absolute despots. Society cannot exist without an apparatus of violent coercion. But neither can it exist if the office holders are irresponsible tyrants free to inflict harm upon those they dislike.

Half of the human race lives in manifest obedience to the lunar rhythm; and there is evidence to show that the psychological and therefore the spiritual life, not only of women, but of men too, mysteriously ebbs and flows with the changes of the moon. There are unreasoned joys, inexplicable miseries, laughters and remorses without a cause. Their sudden and fantastic alternations constitute the ordinary weather of our minds. These moods, of which the more gravely numinous may be hypostasized as gods, the lighter, if we will, as hobgoblins and fairies, are the children of the blood and humours. But the blood and humours obey, among many other masters, the changing moon. Touching the soul directly through the eyes and, indirectly, along the dark channels of the blood, the moon is doubly a divinity.

No one gets angry at a mathematician or a physicist whom he or she doesn't understand at all, or at someone who speaks a foreign language, but rather at someone who tampers with your own language, with this 'relation,' precisely, which is yours.

He dies twice who perishes by his own hand.
