The pursuit of knowledge is, I think, mainly actuated by love of power. And so are all advances in scientific technique. In politics, also, a reformer may have just as strong a love of power as a despot. It would be a complete mistake to decry love of power altogether as a motive. Whether you will be led by this motive to actions which are useful, or to actions which are pernicious, depends upon the social system, and upon your capacities.

One may certainly admire man as a mighty genius of construction, who succeeds in piling an infinitely complicated dome of concepts upon an unstable foundation, and, as it were, on running water. Of course, in order to be supported by such a foundation, his construction must be like one constructed of spiders' webs: delicate enough to be carried along by the waves, strong enough not to be blown apart by every wind.

Buddhism calls anger "corruption of the mind," Manicheism "root of the tree of death." I know this, but what good does it do me to know?

Art is the activity that exalts and denies simultaneously. "No artist tolerates reality," says Nietzsche.

To explain all nature is too difficult a task for any one man or even for any one age. 'Tis much better to do a little with certainty, & leave the rest for others that come after you, than to explain all things by conjecture without making sure of any thing.

It is impossible to live a pleasant life without living wisely and honorably and justly, and it is impossible to live wisely and honorably and justly without living pleasantly. Whenever any one of these is lacking, when, for instance, the man is not able to live wisely, though he lives honorably and justly, it is impossible for him to live a pleasant life.

Revolution is indeed a violent process. But if it is to result only in a change of dictatorship, in a shifting of names and political personalities, then it is hardly worth while. It is surely not worth all the struggle and sacrifice, the stupendous loss in human life and cultural values that result from every revolution. If such a revolution were even to bring greater social well being (which has not been the case in Russia) then it would also not be worth the terrific price paid: mere improvement can be brought about without bloody revolution.

Kant's position is extremely subtle - so subtle, indeed, that no commentator seems to agree with any other as to what it is.

I know of no country in which there is so little independence of mind and real freedom of discussion as in America.

While in the West, the insane are so many that they are put in an asylum, in China the insane are so unusual that we worship them, as anybody who has a knowledge of Chinese literature will testify.

Tomorrow we will be back on the vast ocean.

Nothing is so much to be feared as fear. Atheism may comparatively be popular with God himself.

The Age of Empty Freedom ... does not know that man must first through labour, industry, and art, learn how to know; but it has a certain fixed standard for all conceptions, and an established Common Sense of Mankind always ready and at hand, innate within itself and there present without trouble on its part;-and those conceptions and this Common Sense are to it the measure of the efficient and the real. It has this great advantage over the Age of Science, that it knows all things without having learned anything; and can pass judgment upon whatever comes before it at once and without hesitation,-without needing any preliminary evidence:-'That which I do not immediately comprehend by the conceptions which dwell within me, is nothing,'-says Empty Freedom.

We can not... escape the conclusion that the rule of reasoning by recurrence is irreducible to the principle of contradiction. ...Neither can this rule come to us from experience... This rule, inaccessible to analytic demonstration and to experience, is the veritable type of the synthetic a priori judgment. On the other hand, we can not think of seeing in it a convention, as in some of the postulates of geometry. ...it is only the affirmation of the power of the mind which knows itself capable of conceiving the indefinite repetition of the same act when once this act is possible. The mind has a direct intuition of this power, and experience can only give occasion for using it and thereby becoming conscious of it.

We do not "come into" this world; we come out of it, as leaves from a tree. As the ocean "waves," the universe "peoples." Every individual is an expression of the whole realm of nature, a unique action of the total universe. This fact is rarely, if ever, experienced by most individuals. Even those who know it to be true in theory do not sense or feel it, but continue to be aware of themselves as isolated "egos" inside bags of skin.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first" I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

The Upanishads and the Vedas haunt me. In them I have found eternal compensation, unfathomable power, unbroken peace.

Truths once obtained by legitimate Induction are Facts: these Facts may be again connected, so as to produce higher truths: and thus we advance to 'Successive Generalizations'.

The great tragedy of Science - the slaying of a beautiful hypothesis by an ugly fact.

Man is said to be a reasoning animal. I do not know why he has not been defined as an affective or feeling animal. Perhaps that which differentiates him from other animals is feeling rather than reason. More often I have seen a cat reason than laugh or weep. Perhaps it weeps or laughs inwardly - but then perhaps, also inwardly, the crab resolves equations of the second degree.

A book is a mirror: if an ape looks into it an apostle is hardly likely to look out. We have no words for speaking of wisdom to the stupid. He who understands the wise is wise already.

We no longer have to resort to superstition when faced with the deep problems: Is there a meaning to life? What are we for? What is man?

"They must understand that we can only lose by taking the offensive. Patience and time are my warriors, my champions," thought Kutúzov. He knew that an apple should not be plucked while it is green. It will fall of itself when ripe, but if picked unripe the apple is spoiled, the tree is harmed, and your teeth are set on edge.

Let those flatter who fear; it is not an American art. To give praise which is not due might be well from the venal, but would ill beseem those who are asserting the rights of human nature. They know, and will therefore say, that kings are the servants, not the proprietors of the people.

Just as without the monad there is in general no composition of anything, so also without it there is no knowledge of anything whatsoever, since it is a pure light, most authoritative over everything in general, and it is sun-like and ruling, so that in each of these respects it resembles God, and especially because it has the power of making things cohere and combine, even when they are composed of many ingredients and are very different from one another, just as he made this universe harmonious and unified out of things which are likewise opposed.

I cannot contribute anything to this world because I only have one method: agony.

Live as on a mountain. ...Let men see, let them know a real man who lives according to nature. If they cannot endure him, let them kill him. For that is better than to live thus.

Originality is a thing we constantly clamour for, and constantly quarrel with; as if, observes our author himself, any originality but our own could be expected to content us! In fact all strange thing are apt, without fault of theirs, to estrange us at first view, and unhappily scarcely anything is perfectly plain, but what is also perfectly common.

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.

Progress in civilization seems possible only in interludes when history is idling.

People do not cooperate under the division of labor because they love or should love one another. They cooperate because this best serves their own interests. Neither love nor charity nor any other sympathetic sentiments but rightly understood selfishness is what originally impelled man to adjust himself to the requirements of society, to respect the rights and freedoms of his fellow men and to substitute peaceful collaboration for enmity and conflict.

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.

The mollusk's motto would be: one must live to build one's house, and not build one's house to live in.

We now live in a technologically prepared environment that blankets the earth itself. The humanly contrived environment of electric information and power has begun to take precedence over the old environment of "nature." Nature, as it were, begins to be the content of our technology.

It lays down, as is generally known, that our speculations upon all subjects whatsoever, pass necessarily through three successive stages: a Theological stage, in which free play is given to spontaneous fictions admitting of no proof; the Metaphysical stage, characterized by the prevalence of personified abstractions or entities; lastly, the Positive stage, based upon an exact view of the real facts of the case.

What does it mean to have a god? or, what is God? Answer: A god means that from which we are to expect all good and to which we are to take refuge in all distress, so that to have a God is nothing else than to trust and believe Him from the [whole] heart; as I have often said that the confidence and faith of the heart alone make both God and an idol. If your faith and trust be right, then is your god also true; and, on the other hand, if your trust be false and wrong, then you have not the true God; for these two belong together faith and God. That now, I say, upon which you set your heart and put your trust is properly your god.

Two things fill the mind with ever-increasing wonder and awe, the more often and the more intensely the mind of thought is drawn to them: the starry heavens above me and the moral law within me.

Man's urge for change and his need for stability have always balanced and checked each other, and our current vocabulary, which distinguishes between two factions, the progressives and the conservatives, indicates a state of affairs in which this balance has been thrown out of order. No civilization - the man-made artifact to house successive generations - would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.

The human soul has need of disciplined participation in a common task of public value, and it has need of personal initiative within this participation. The human soul has need of security and also of risk. The fear of violence or of hunger or of any other extreme evil is a sickness of the soul. The boredom produced by a complete absence of risk is also a sickness of the soul.

I do not say this, that I think there should be no difference of opinions in conversation, nor opposition in men's discourses... 'Tis not the owning one's dissent from another, that I speak against, but the manner of doing it.

Technology is in its essence something that human beings cannot master of their own accord.

But now persecution is good, because it exists; every law which originated in ignorance and malice, and gratifies the passions from whence it sprang, we call the wisdom of our ancestors: when such laws are repealed, they will be cruelty and madness; till they are repealed, they are policy and caution.

Mr. Neo-Angular - I am doing my duty. My ethics are based on dogma, not on feeling. Vertue - I know that a rule is to be obeyed because it is a rule and not because it appeals to my feelings at the moment.

The Value of myth is that it takes all the things you know and restores to them the rich significance which has been hidden by the veil of familiarity.

Last words are for fools who haven't said enough.

It is the business of the future to be dangerous; and it is among the merits of science that it equips the future for its duties.

The first character of a general idea so resulting is that it is living feeling. A continuum of this feeling, infinitesimal in duration, but still embracing innumerable parts, and also, though infinitesimal, entirely unlimited, is immediately present. And in its absence of boundedness a vague possibility of more than is present is directly felt.
