The doctrine that there is as much science in a subject as... mathematics in it, or as much... measurement or 'precision' in it, rests upon... misunderstanding.

If two right lines cut one another, they will form the angles at the vertex equal. ...This... is what the present theorem evinces, that when two right lines mutually cut each other, the vertical angles are equal. And it was first invented according to Eudemus by Thales...

One could construe the life of man as a great discourse in which the various people represent different parts of speech (the same might apply to states). How many people are just adjectives, interjections, conjunctions, adverbs? How few are substantives, active verbs, how many are copulas? Human relations are like the irregular verbs in a number of languages where nearly all verbs are irregular.

Wherever we turn we find that the real obstacles to peace are human will and feeling, human convictions, prejudices, opinions. If we want to get rid of war we must get rid first of all of its psychological causes. Only when this has been done will the rulers of the nations even desire to get rid of the economic and political causes.

An evil may be real, tho' its cause has no relation to us: It may be real, without being peculiar: It may be real, without shewing itself to others: It may be real, without being constant: And it may be real, without falling under the general rules. Such evils as these will not fail to render us miserable, tho' they have little tendency to diminish pride: And perhaps the most real and the most solid evils of life will be found of this nature.

Analytic philosophers - both in the 'constructivist' camp and in the camp that studies 'the ordinary use of words' - are disturbingly unanimous in regarding 2-valued logic as having a privileged position: privileged, not just in the sense of corresponding to the way we do speak, but in the sense of having no serious rival for logical reasons. If the foregoing analysis is correct, this is a prejudice of the same kind as the famous prejudice in favor of a privileged status for Euclidean geometry (a prejudice that survives in the tendency to cite 'space has three dimensions' as some kind of 'necessary' truth). One can go over from a 2-valued to a 3-valued logic without totally changing the meaning of 'true' and 'false'; and not just in silly ways, like the ones usually cited (e.g. equating truth with high probability, falsity with low probability, and middlehood with 'in between' probability).

Though we may prefer ourselves to the universe, we nonetheless loathe ourselves much more than we suspect. If the wise man is so rare a phenomenon, it is because he seems unshaken by the aversion which, like all beings, he must feel for himself.

He would be the finer gentleman that should leave the world without having tasted of lying or pretence of any sort, or of wantonness or conceit.

I've learned from the Bhagavad Gita and other teachings of our culture to detach myself from the results of what I do, because those are not in my hands. The context is not in your control, but your commitment is yours to make, and you can make the deepest commitment with a total detachment about where it will take you. You want it to lead to a better world, and you shape your actions and take full responsibility for them, but then you have detachment. And that combination of deep passion and deep detachment allows me always to take on the next challenge because I don't cripple myself, I don't tie myself in knots. I function like a free being. I think getting that freedom is a social duty because I think we owe it to each other not to burden each other with prescription and demands. I think what we owe each other is a celebration of life and to replace fear and hopelessness with fearlessness and joy.

If a false thought is so much as expressed boldly and clearly, a great deal has already been gained.

We have just seen that, apart from money-capital, circulating capital is only another name for commodity-capital. But to the extent that labour power circulates in the market,it is not capital, no form of commodity-capital. It is not capital at all; the labourer is not a capitalist, although he brings a commodity to market, namely his own skin.

The louder he talked of his honor, the faster we counted our spoons.

For those who want 'to change life", 'to reinvent love,' God is nothing but a hindrance.

Passion is like suffering, and like suffering it creates its object. It is easier for the fire to find something to burn than for something combustible to find the fire.

It must be borne in mind that it is through the channel of the child that the development of the mature man must go, and that the present ideas of the educating or training of the latter in the school and the family - even the family of the liberal or radical - are such as to stifle the natural growth of the child. Every institution of our day, the family, the State, our moral codes, sees in every strong, beautiful, uncompromising personality a deadly enemy; therefore every effort is being made to cramp human emotion and originality of thought in the individual into a straight-jacket from its earliest infancy; or to shape every human being according to one pattern; not into a well-rounded individuality, but into a patient work slave, professional automaton, tax-paying citizen, or righteous moralist.

A man may own a thousand acres of land, and yet he still sleeps upon a bed of five feet.

Yes, yes, I see it all! - an enormous social activity, a mighty civilization, a profuseness of science, of art, of industry, of morality, and afterwords, when we have filled the world with industrial marvels, with great factories, with roads, museums and libraries, we shall fall exhausted at the foot of it all, and it will subsist - for whom? Was man made for science or was science made for man?

I often asked myself the following question. There is no doubt that at all times for many men one of the greatest tortures of their lives has been the contact, the collision with the folly of their neighbours. And yet how is it that there has never been attempted - I think this is so - a study on this matter, an Essay on Folly? For the pages of Erasmus do not treat of this aspect of the matter.

Would not all we mean by "communication between mind and mind" be provided for if we suppose that common knowledge comes about, not from our explaining things to one another, but from things explaining themselves in the same terms to us all? Accepting the object as its own interpreter, as its own "medium of communication," do we not begin to understand what is utterly dark on any other view, how it comes to pass that the resulting knowledge is a common possession?

But many of us seek community solely to escape the fear of being alone. Knowing how to be solitary is central to the art of loving. When we can be alone, we can be with others without using them as a means of escape.

There is no one at the Communion table who retains against you even the least of your sins, no one, unless you yourself do it. So cast them away from yourself, and the recollection of them, lest in it your retain them; and cast the recollection of your having cast your sins away, lest in it you retain them.

A great soul, any sincere soul, knows not what he is,-alternates between the highest height and the lowest depth; can, of all things, the least measure-Himself! What others take him for, and what he guesses that he may be; these two items strangely act on one another, help to determine one another. With all men reverently admiring him; with his own wild soul full of noble ardors and affections, of whirlwind chaotic darkness and glorious new light; a divine Universe bursting all into godlike beauty round him, and no man to whom the like ever had befallen, what could he think himself to be?

It is hard to believe that this simple truth is not understood by those leaders who forbid their followers to use effective contraceptive methods. They express a preference for 'natural' methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.

The most important person is the one you are with in this moment.

If a man makes the press utter atrocious things he becomes as answerable for them as if he had uttered them by word of mouth. Mr. Jefferson has said in his inaugural speech, that "error of opinion might be tolerated, when reason was left free to combat it." This is sound philosophy in cases of error. But there is a difference between error and licentiousness.

In a field of ripening corn I came to a place which had been trampled down by some ruthless foot; and as I glanced amongst the countless stalks, every one of them alike, standing there so erect and bearing the full weight of the ear, I saw a multitude of different flowers, red and blue and violet. How pretty they looked as they grew there so naturally with their little foliage! But, thought I, they are quite useless; they bear no fruit; they are mere weeds, suffered to remain only because there is no getting rid of them. And yet, but for these flowers, there would be nothing to charm the eye in that wilderness of stalks. They are emblematic of poetry and art, which, in civic life-so severe, but still useful and not without its fruit-play the same part as flowers in the corn.

In the new order a Locke was free-with almost no danger of being interfered with-to think his sublime thoughts, to seek the first causes of all things, to understand the nature of things. He could talk with his friends and teach the young. And there was money enough. The academies and universities satisfied Socrates' demand to be fed in the prytaneum.

Tyranny offers relief from the burden of sanity and a licence to enact forbidden impulses of hatred and violence. By acting on these impulses and releasing them in their subjects tyrants give people a kind of happiness, which as individuals they may be incapable of achieving.

Absolute relativism, which is neither more nor less than skepticism, in the most modern sense of the term, is the supreme triumph of the reasoning reason.

We rarely find anyone who can say he has lived a happy life, and who, content with his life, can retire from the world like a satisfied guest.

The years as they pass plunder us of one thing after another.

Saturninus said, "Comrades, you have lost a good captain to make him an ill general."

We need better government, no doubt about it. But we also need better minds, better friendships, better marriages, better communities.

Of the various executive abilities, no one excited more anxious concern than that of placing the interests of our fellow-citizens in the hands of honest men, with understanding sufficient for their stations. No duty is at the same time more difficult to fulfil. The knowledge of character possessed by a single individual is of necessity limited. To seek out the best through the whole Union, we must resort to the information which from the best of men, acting disinterestedly and with the purest motives, is sometimes incorrect.

The poor, stupid, free American citizen! Free to starve, free to tramp the highways of this great country, he enjoys universal suffrage, and, by that right, he has forged chains about his limbs. The reward that he receives is stringent labor laws prohibiting the right of boycott, of picketing, in fact, of everything, except the right to be robbed of the fruits of his labor.

If you punish him for what he sees you practise yourself, he... will be apt to interpret it the peevishness and arbitrary imperiousness of a father, who, without any ground for it, would deny his son the liberty and pleasure he takes himself.

There are some remedies worse than the disease.

It is said that "being" is the most universal and the emptiest concept. As such it resists every attempt at definition. Nor does this most universal and thus indefinable concept need any definition. Everybody uses it constantly and also already understands what is meant by it.

In no other country in the world is the love of property keener or more alert than in the United States, and nowhere else does the majority display less inclination toward doctrines which in any way threaten the way property is owned.

Just as when a man commits suicide ne negates the body, this rational limit of subjectivity, so when he lapses into fantastic and trascendental practice he associates himself with embodied divine and ghostly appearances, namely, he negates in practise the difference between imagination and perception.

Let men be happy, informed, skillful, well behaved, and productive.

However long Jewish, Christian and Muslim theologians struggle to find multiple meanings in this text, the dominant seems to be this: Abraham's unquestioning willingness to heed gods command to sacrifice the thing he loved most is what qualified him to become the father of what are called still the Abrahamic faiths.

There always comes a time in history when the person who dares to say that 2+2=4 is punished by death. And the issue is not what reward or what punishment will be the outcome of that reasoning. The issue is simply whether or not 2+2=4.

By far the most valuable things, which we know or can imagine, are certain states of consciousness, which may roughly be described as the pleasures of human intercourse and the enjoyment of beautiful objects. No one, probably, who has asked himself the question, has ever doubted that personal affection and the appreciation of what is beautiful in Art or Nature, are good in themselves; nor, if we consider strictly what things are worth having purely for their own sakes, does it appear probable that any one will think that anything else has nearly so much value as the things which are included under these two heads.

The world is sacred because it gives an inkling of a meaning that escapes us.
