A man has a right to use a saw, an axe, a plane, separately; may he not combine their uses on the same piece of wood? He has a right to use his knife to cut his meat, a fork to hold it; may a patentee take from him the right to combine their use on the same subject? Such a law, instead of enlarging our conveniences, as was intended, would most fearfully abridge them, and crowd us by monopolies out of the use of the things we have.

Continuously thou wilt look at human things as smoke and nothing at all; especially if thou reflectest at the same time, that what has once changed will never exist again in the infinite duration of time. But thou, in what a brief space of time is thy existence? And why art thou not content to pass through this short time in an orderly way?

There was a loud echo of Hume in Mach's work, as both emphasized the tangibility of all knowledge-ultimately, all knowledge is based in the senses. Mach also emphasized the internal nature of all knowledge, in that it is experienced in the mind. Finally, he emphasized the importance of quantitative and mathematical methods and models to understand sensory experience.

At this point in history when all things which concern man and the structure and elements of history itself are suddenly revealed to us in a new light, it behooves us in our scientific thinking to become masters of the situation, for it is not inconceivable that sooner than we suspect, as has often been the case before in history, this vision may disappear, the opportunity may be lost, and the world will once again present a static, uniform, and inflexible countenance.

This right which you have, is not founded any more than his upon any quality or any merit in yourself which renders you worthy of it. Your soul and your body are, of themselves, indifferent to the state of boatman or that of duke; and there is no natural bond that attaches them to one condition rather than to another.

As there are a very great variety of religious sects in the world (and which are probably adapted to different constitutions under different circumstances, seeing there are many good and conscientious characters in each), it is particularly recommended, as a means of uniting the inhabitants of the village into one family, that while each faithfully adheres to the principles which he most approves, at the same time all shall think charitably of their neighbours respecting their religious opinions, and not presumptuously suppose that theirs alone are right.

Nothing that was worthy in the past departs; no truth or goodness realized by man ever dies, or can die.

Tell me what kind of man governs a People, you tell me, with much exactness, what the net sum-total of social worth in that People has for some time been.

Environments are not just containers, but are processes that change the content totally.

I do not feel obliged to believe that the same God who has endowed us with senses, reason, and intellect has intended us to forgo their use and by some other means to give us knowledge which we can attain by them.

Throughout the years in which the US was punishing countries that departed from fiscal prudence, it was borrowing on a colossal scale to finance tax cuts and fund its over-stretched military commitments. Now, with federal finances critically dependent on continuing large inflows of foreign capital, it will be the countries that spurned the American model of capitalism that will shape America's economic future.

Out of the shadow of the abstract man, who thinks for the pleasure of thinking, emerges the organic man, who thinks because of a vital imbalance, and who is beyond science and art.

Destruction perfects that which is good; for the good cannot appear on account of that which conceals it. The good is least good whilst it is thus concealed. The concealment must be removed so that the good may be able freely to appear in its own brightness. For example, the mountain, the sand, the earth, or the stone in which a metal has grown is such a concealment. Each one of the visible metals is a concealment of the other six metals.

I have studied these things - you have not.

Of course, not everything old is beautiful, any more than everything black, or everything white, or everything young. But the notion that old means ugly is every bit as harmful as the prejudice that black is ugly. In one way it is even more pernicious. The notion that only what is new and young is beautiful poisons our relationship to the past and to our own future. It keeps us from understanding our roots and the greatest works of our culture and other cultures. It also makes us dread what lies ahead of us and leads many to shirk reality.

You say that I have been dished up to you as an antifederalist, and ask me if it be just. My opinion was never worthy enough of notice to merit citing; but since you ask it I will tell it you. I am not a Federalist, because I never submitted the whole system of my opinions to the creed of any party of men whatever in religion, in philosophy, in politics, or in anything else where I was capable of thinking for myself. Such an addiction is the last degradation of a free and moral agent. If I could not go to heaven but with a party, I would not go there at all. Therefore I protest to you I am not of the party of federalists. But I am much farther from that than of the Antifederalists.

What! all of us, Christians, not only profess to love one another, but do actually live one common life; we whose social existence beats with one common pulse-we aid one another, learn from one another, draw ever closer to one another to our mutual happiness, and find in this closeness the whole meaning of life!-and to-morrow some crazy ruler will say some stupidity, and another will answer in the same spirit, and then I must go expose myself to being murdered, and murder men-who have done me no harm-and more than that, whom I love. And this is not a remote contingency, but the very thing we are all preparing for, which is not only probable, but an inevitable certainty.

The brutality of a man purely motivated by monetary considerations ... often does not appear to him at all as a moral delinquency, since he is aware only of a rigorously logical behavior, which draws the objective consequences of the situation.

However, the disappearance of domination does not entail freedom. Instead, it makes freedom and constraint coincide. Thus, the achievement-subject gives itself over to compulsive freedom--that is, to the free constraint of maximizing achievement. Excess work and performance escalate into auto-exploitation.

With the exception of professional rationalists, today people despair of true knowledge. If the only significant history of human thought were to be written, it would have to be history of its successive regrets and impotences.

Between ourselves and our real natures we interpose that wax figure of idealizations and selections which we call our character.

God may not play dice but he enjoys a good round of Trivial Pursuit every now and again.

Contrary to earlier prejudices, there is nothing inherently progressive about evolution.

I'm delighted to hear someone make the claim that there is moral progress because it can be such a incendiary thing to say, and its something that I say and deeply believe in.

The cup of life is not so shallow

That we have drained the best 

That all the wine at once we swallow 

And lees make all the rest.

The effects of mescalin or LSD can be, in some respects, far more satisfying than those of alcohol. To begin with, they last longer; they also leave behind no hangover, and leave the mental faculties clear and unimpaired. They stimulate the faculties and produce the ideal ground for a peak experience.

Do not listen to the reasoners; there has been too much reasoning in France, and reasoning has banished reason. Put aside your fears and reservations, and trust the infallible instinct of your conscience. Do you want to redeem yourselves in your own eyes? Do you want to acquire the right of self-esteem? Do you want to accomplish a sovereign act? . . . Recall your sovereign.

As the French say, there are three sexes - men, women, and clergymen.

Where the world comes in my way - and it comes in my way everywhere - I consume it to quiet the hunger of my egoism. For me you are nothing but - my food, even as I too am fed upon and turned to use by you. We have only one relation to each other, that of usableness, of utility, of use.

We may become the makers of our fate when we have ceased to pose as its prophets.

Historically, the errors committed by a truly revolutionary movement are infinitely more fruitful than the infallibility of the cleverest Central Committee.

The ancient Egyptians had a superstitious antipathy to the sea; a superstition nearly of the same kind prevails among the Indians; and the Chinese have never excelled in foreign commerce.

In matters that are so obscure and far beyond our vision, we find in Holy Scripture passages which can be interpreted in very different ways without prejudice to the faith we have received. In such cases, we should not rush in headlong and so firmly take our stand on one side that, if further progress in the search for truth justly undermines this position, we too fall with it.

As for us, my little friend, we entered [the Communist Party] because we were tired of dying of hunger.

A marvel that has nothing to offer, democracy is at once a nation's paradise and its tomb.

But what is liberty without wisdom, and without virtue? It is the greatest of all possible evils; for it is folly, vice, and madness, without tuition or restraint.

This morning I thought, hence lost my bearings, for a good quarter of an hour.

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.

You must not murder. (Exodus 20:13) Q. What does this mean? A. We should fear and love God so that we may not hurt or harm our neighbor in his body, but help and befriend him in every bodily need [in every need and danger of life and body].

I believe in intuitions and inspirations. I sometimes feel that I am right. I do not know that I am. When two expeditions of scientists, financed by the Royal Academy, went forth to test my theory of relativity, I was convinced that their conclusions would tally with my hypothesis. I was not surprised when the eclipse of May 29, 1919, confirmed my intuitions. I would have been surprised if I had been wrong.

Instead of wishing to see more doctors made by women joining what there are, I wish to see as few doctors, either male or female, as possible. For, mark you, the women have made no improvement - they have only tried to be men and they have only succeeded in being third-rate men.

The Reformation was a popular uprising, and for a century and a half drenched Europe in blood. The beginnings of the Scientific movement were confined to a minority among the intellectual elite.... The worst that happened to men of science was that Galileo suffered an honorable detention and a mild reproof, before dying peacefully in his bed. The way in which the persecution of Galileo has been remembered is a tribute to the quiet commencement of the most intimate change in outlook which the human race had yet encountered. Since a babe was born in a manger, it may be doubted whether so great a thing has happened with so little stir.

Well, it was healthy to miss once in a while. It kept self-confidence balanced at a point safely short of arrogance.
