After Riemann had made known his discoveries, mathematicians busied themselves with working out his system of geometrical ideas formally; chief among these were Christoffel, Ricci, and Levi-Civita. Riemann... clearly left the real development of his ideas in the hands of some subsequent scientist whose genius as a physicist could rise to equal flights with his own as a mathematician. After a lapse of seventy years this mission has been fulfilled by Einstein.

Gentile himself call his doctrine 'absolute formalism': there is no; 'matter' apart from the pure 'form' of acting. 'The only matter there is in the spiritual act is the form itself, as activity.'

I don't believe in flying saucers... The energy requirements of interstellar travel are so great that it is inconceivable to me that any creatures piloting their ships across the vast depths of space would do so only in order to play games with us over a period of decades.

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.

In all persuasions the bigots are persecutors; the men of a cool and reasonable piety are favourers of toleration; because the former sort of men not taking the pains to be acquainted with the grounds of their adversaries tenets, conceive them to be so absurd and monstrous, that no man of sense can give into them in good earnest. For which reason they are convinced that some oblique bad motive induces them to pretend to the belief of such doctrines, and to the maintaining of them with obstinacy. This is a very general principle in all religious differences, and it is the corner stone of all persecution.

Where danger shews it self, apprehension cannot, without stupidity, be wanting; where danger is, sense of danger should be; and so much fear as should keep us awake, and excite our attention, industry, and vigour; but not to disturb the calm use of our reason, nor hinder the execution of what that dictates.

I mean, a genuinely productive society. I mean you could produce plenty of goods without much freedom, but I think the whole sort of creative life of man is ultimately impossible without a considerable measure of individual freedom, of initiative, creation, all these things which we value, and I think value properly, are impossible without a large measure of freedom.

I have only one real message in this lecture, and that is: consciousness is a biological phenomenon, like photosynthesis, digestion, mitosis-you know all the biological phenomena-and once you accept that, most, if not all about the hard problems of consciousness simply evaporate.

The startling truth is that our best efforts for civil rights, international peace, population control, conservation of natural resources, and assistance to the starving of the earth-urgent as they are-will destroy rather than help if made in the [current] spirit. For, as things stand, we have nothing to give. If our own riches and our own way of life are not enjoyed here, they will not be enjoyed anywhere else. Certainly they will supply the immediate jolt of energy and hope that methedrine, and similar drugs, give in extreme fatigue. But peace can be made only by those who are peaceful, and love can be shown only by those who love. No work of love will flourish out of guilt, fear, or hollowness of heart, just as no valid plans for the future can be made by those who have no capacity for living now.

At the parting of ways in the life-order, where the question is between the new creation or decay, that man will be decisive for new creation who is able on his own initiative to seize the helm and steer a course of his own choosing - even if that course be opposed to the will of the masses. Should the emergence of such persons become impossible a lamentable shipwreck will be inevitable.

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.

It seems that the creative faculty, and the critical faculty, cannot exist together in their highest perfection.

I am writing to you to tell you of my decision to return to your Government the Carl von Ossietzsky medal for peace. I do so reluctantly and after two years of private approaches on behalf of Heinz Brandt, whose continued imprisonment is a barrier to coexistence, relaxation of tension and understanding between East and West... I regret not to have heard from you on this subject. I hope that you will yet find it possible to release Brandt through an amnesty which would be a boon to the cause of peace and to your country.

I had always hoped that the younger generation receiving their early impressions after the flame of liberty had been kindled in every breast, & had become as it were the vital spirit of every American, that the generous temperament of youth, analogous to the motion of their blood, and above the suggestions of avarice, would have sympathized with oppression wherever found, and proved their love of liberty beyond their own share of it.

Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. And I gave her space to repent of her fornication; and she repented not. Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.

Analytical philosophy was very interesting. It always struck me as being very interesting and full of tremendous intellectual curiosities. It is wonderful to see the mind at work in such an intense manner, but, for me, it was still too far removed from my own issues.

To suffer is the great modality of taking the world seriously.

My first advice (on how not to grow old) would be to choose you ancestors carefully. Although both my parents died young, I have done well in this respect as regards my other ancestors. My maternal grandfather, it is true, was cut off in the flower of his youth, at the age of sixty-seven, but my other three grandparents all lived to be over eighty. Of remoter ancestors I can only discover one who did not live to a great age, and he died of a disease which is now rare, namely, having his head cut off.

I see a clock, but I cannot envision the clockmaker. The human mind is unable to conceive of the four dimensions, so how can it conceive of a God, before whom a thousand years and a thousand dimensions are as one?

Many conflicts within Third World countries are related to the practice of exploiting resources faster than nature can renew them or diverting them away from where people need them. Dams in every society have become major sources of conflict. As water scarcity grows, neighbors, families turn against each other.

When the general population no longer constitutes the armed forces, when the army is no longer the people in arms, then empires fall. Today all armies are again tending to become mercenary armies.

The superior man accords with the course of the Mean. Though he may be all unknown, unregarded by the world, he feels no regret. It is only the sage who is able for this.

May we not say, perhaps, that the evil man is annihilated because he wished to be annihilated, or that he did not wish strongly enough to eternalize himself because he was evil? May we say that it is not believing in the other life which causes a man to be good, but rather that being good causes him believe in it? And what is being good and being evil? These states belong to the sphere of ethics, not of religion; or rather, does not the doing good though being evil pertain to ethics, and the being good [forgivable] though doing evil, to religion?

Apart from any other basis which might justify a superiority, education, as a power, raised him who possessed it over the weak, who lacked it, and the educated man counted in his circle, however large or small it was, as the mighty, the powerful, the imposing one: for he was an authority.

Knowledge is the food of the soul; and we must take care, my friend, that the Sophist does not deceive us when he praises what he sells, like the dealers wholesale or retail who sell the food of the body; for they praise indiscriminately all their goods, without knowing what are really beneficial or hurtful.

We share bodies with two eyes, ten fingers, ten toes; we share life on this earth; we share capitalist regimes of production and exploitation; we share common dreams of a better future.

Whoever finishes a revolution only halfway, digs his own grave.

I think if I had met him [Lenin] without knowing who he was, I should not have guessed that he was a great man; he struck me as too opinionated and narrowly orthodox. His strength comes, I imagine, from his honesty, courage, and unwavering faith-religious faith in the Marxian gospel, which takes the place of the Christian martyr's hopes of Paradise, except that it is less egotistical... I went to Russia a Communist; but contact with those who have no doubts has intensified a thousandfold my own doubts, not as to Communism in itself, but as to the wisdom of holding a creed so firmly that for its sake men are willing to inflict widespread misery.

The mere word 'design' by itself has no consequences and explains nothing. It is the barrenest of principles. The old question of whether there is design is idle. The real question is what is the world, whether or not it have a designer - and that can be revealed only by the study of all nature's particulars.

The liar is a person who uses the valid designations, the words, in order to make something which is unreal appear to be real. He says, for example, "I am rich," when the proper designation for his condition would be "poor." He misuses fixed conventions by means of arbitrary substitutions or even reversals of names. If he does this in a selfish and moreover harmful manner, society will cease to trust him and will thereby exclude him. What men avoid by excluding the liar is not so much being defrauded as it is being harmed by means of fraud. Thus, even at this stage, what they hate is basically not deception itself, but rather the unpleasant, hated consequences of certain sorts of deception. It is in a similarly restricted sense that man now wants nothing but truth: he desires the pleasant, life-preserving consequences of truth. He is indifferent toward pure knowledge which has no consequences; toward those truths which are possibly harmful and destructive he is even hostilely inclined.

The ideas of Freud were popularized by people who only imperfectly understood them, who were incapable of the great effort required to grasp them in their relationship to larger truths, and who therefore assigned to them a prominence out of all proportion to their true importance.

There is no such thing as gratitude in international politics.

By means of ever more effective methods of mind-manip­ulation, the democracies will change their nature; the quaint old forms- elections, parliaments, Supreme Courts and all the rest-will remain. The underlying substance will be a new kind of non-violent totalitari­anism. All the traditional names, all the hallowed slo­gans will remain exactly what they were in the good old days. Democracy and freedom will be the theme of every broadcast and editorial-but democracy and free­dom in a strictly Pickwickian sense. Meanwhile the ruling oligarchy and its highly trained elite of sol­diers, policemen, thought-manufacturers and mind-manipulators will quietly run the show as they see fit.

To speak frankly, the family bond in the civilizee regime' causes fathers to desire the death of their children and children to desire the death of their fathers.

We do not merely study the past: we inherit it, and inheritance brings with it not only the rights of ownership, but the duties of trusteeship. Things fought for and died for should not be idly squandered. For they are the property of others, who are not yet born.

A man may be in as just possession of Truth as of a City, and yet be forced to surrender.

All the cruelty and torment of which the world is full is in fact merely the necessary result of the totality of the forms under which the will to live is objectified.

The longing for guidance, for love and succor, provides the stimulus for the growth of a social or moral conception of God. This is the God of Providence, who protects, decides, rewards and punishes. This is the God who, according to man's widening horizon, loves and provides for the life of the race, or of mankind, or who even loves life itself. He is the comforter in unhappiness and in unsatisfied longing, the protector of the souls of the dead. This is the social or moral idea of God.

A commodity appears, at first sight, a very trivial thing, and easily understood.Its analysis shows that it is, in reality, a very queer thing, abounding in metaphysical subtleties and theological niceties.

Technologies themselves, regardless of content, produce a hemispheric bias in the users.

I shall have to test the theory of my father Parmenides, and contend forcibly that after a fashion not-being is and on the other hand in a sense being is not. For unless these statements are either disproved or accepted, no one who speaks about false words, or false opinion whether images or likenesses or imitations or appearances about the arts which have to do with them, can ever help being forced to contradict himself and make himself ridiculous.

That which comes after ever conforms to that which has gone before.

He was free, free in every way, free to behave like a fool or a machine, free to accept, free to refuse, free to equivocate; to marry, to give up the game, to drag this death weight about with him for years to come. He could do what he liked, no one had the right to advise him, there would be for him no Good or Evil unless he thought them into being.

Ivan Ilych's life had been most simple and most ordinary and therefore most terrible.

Greater intelligence, wealth and opportunity, for example, allow a person to achieve ends he could not rationally contemplate otherwise.

What strikes one here above all is the crudely empirical conception of profit derived from the outlook of the ordinary capitalist, which wholly contradicts the better esoteric understanding of Adam Smith.

In fact, this infinitesimally spread-out consciousness is a direct feeling of its contents as spread out. In an infinitesimal interval we directly perceive the temporal sequence of its beginning, middle, and end... Now upon this interval follows another, whose beginning is the middle of the former, and whose middle is the end of the former. Here we have an immediate perception of the temporal sequence of its beginning, middle and end, or say, of the second, third, and fourth instants.

Doutbless, revenge is not always sweet, once it is consummated we feel inferior to our victim, or else we are tangled in the subtleties of remorse; so vengeance too has its venom, though it comes closer to what we are, to what we feel, to the very law of the self; it is also healthier than magnanimity. The Furies were held to antedate the gods, Zeus included. Vengeance before Divinity! This is the Major intuition of ancient mythology. p. 70.

Serious occupation is labor that has reference to some want.

I never knew a writer's wife who wasn't beautiful.
