Since ancient times, philosophers have maintained that to strive too hard for one's own happiness is self-defeating.

Important though the general concepts and propositions may be with which the modern industrious passion for axiomatizing and generalizing has presented us, in algebra perhaps more than anywhere else, nevertheless I am convinced that the special problems in all their complexity constitute the stock and core of mathematics; and to master their difficulties requires on the whole the harder labor.

Our "Theories of Taste," as they are called, wherein the deep, infinite, unspeakable Love of Wisdom and Beauty, which dwells in all men, is "explained," made mechanically visible, from "Association" and the like, ...

When it is a question of money, everybody is of the same religion.

Mathematicians do not study objects, but the relations between objects; to them it is a matter of indifference if these objects are replaced by others, provided that the relations do not change. Matter does not engage their attention, they are interested in form alone.

The philosophers who wished us to have the gods for our friends rank the friendship of the holy angels in the fourth circle of society, advancing now from the three circles of society on earth to the universe, and embracing heaven itself. And in this friendship we have indeed no fear that the angels will grieve us by their death or deterioration. But as we cannot mingle with them as familiarly as with men (which itself is one of the grievances of this life), and as Satan, as we read, sometimes transforms himself into an angel of light, to tempt those whom it is necessary to discipline, or just to deceive, there is great need of God's mercy to preserve us from making friends of demons in disguise, while we fancy we have good angels for our friends; for the astuteness and deceitfulness of these wicked spirits is equalled by their hurtfulness.

The law of faith, being a covenant of free grace, God alone can appoint what shall be necessarily believed by everyone whom He will justify. What is the faith which He will accept and account for righteousness, depends wholly on his good pleasure. For it is of grace, and not of right, that this faith is accepted. And therefore He alone can set the measures of it: and what he has so appointed and declared is alone necessary. No-body can add to these fundamental articles of faith; nor make any other necessary, but what God himself hath made, and declared to be so. And what these are which God requires of those who will enter into, and receive the benefits of the new covenant, has already been shown. An explicit belief of these is absolutely required of all those to whom the gospel of Jesus Christ is preached, and salvation through his name proposed.

I read your piece on Plato. Holmes, when you strike at a king, you must kill him.

You have to study a great deal to know a little.

For a long time there have been no true sovereigns, monarchs by divine right capable of wielding sword and scepter, and symbols of a higher human ideal. More than a century ago, Juan Donoso Cortés stated that no kings existed capable of proclaiming themselves as such except "by the will of the nation," adding that, even if any had existed, they would not have been recognized. The few monarchies still surviving are notoriously impotent and empty, while the traditional nobility has lost its essential character as a political class and any existential prestige and rank along with it. Its current representatives may still interest our contemporaries when put on the same plane as film actors and actresses, sport heroes and opera stars, and when through some private, sentimental, or scandalous chance, they serve as fodder for magazine articles.

I have no great faith in political arithmetic, and I mean not to warrant the exactness of either of these computations.

No doubt a tumult caused by local and temporary irritation ought to be suppressed with promptitude and vigour. Such disturbances, for example, as those which Lord George Gordon raised in 1780, should be instantly put down with the strong hand. But woe to the Government which cannot distinguish between a nation and a mob! Woe to the Government which thinks that a great, a steady, a long continued movement of the public mind is to be stopped like a street riot! This error has been twice fatal to the great House of Bourbon. God be praised, our rulers have been wiser. The golden opportunity which, if once suffered to escape, might never have been retrieved, has been seized. Nothing, I firmly believe, can now prevent the passing of this noble law, this second Bill of Rights.

Ever since prehistoric antiquity one field of study after another has crossed the divide between what the historian might call its prehistory as a science and its history proper. These transitions to maturity have seldom been so sudden or so unequivocal as my necessarily schematic discussion may have implied. But neither have they been historically gradual, coextensive, that is to say, with the entire development of the fields within which they occurred.

Art is the imposing of a pattern on experience, and our aesthetic enjoyment in recognition of the pattern.

I wish we could derive the rest of the phenomena of nature by the same kind of reasoning from mechanical principles; for I am induced by many reasons to suspect that they may all depend upon certain forces by which the particles of bodies, by some causes hitherto unknown, are either mutually impelled towards each other, and cohere in regular figures, or are repelled and recede from each other; which forces being unknown, philosophers have hitherto attempted the search of nature in vain; but I hope the principles here laid down will afford some light either to that or some truer method of philosophy.

We now come to a decisive step of mathematical abstraction: we forget about what the symbols stand for... [The mathematician] need not be idle; there are many operations which he may carry out with these symbols, without ever having to look at the things they stand for.

Even when nothing happens, everything seems too much for me. What can be said, then, in the presence of an event, any event?

Our entire linear and accumulative culture collapses if we cannot stockpile the past in plain view. "

In looking at this wreck of Governments in all European countries, there is one consideration that suggests itself, sadly elucidative of our modern epoch. These Governments, we may be well assured, have gone to anarchy for this one reason inclusive of every other whatsoever, That they were not wise enough; that the spiritual talent embarked in them, the virtue, heroism, intellect, or by whatever other synonyms we designate it, was not adequate,-probably had long been inadequate, and so in its dim helplessness had suffered, or perhaps invited falsity to introduce itself; had suffered injustices, and solecisms, and contradictions of the Divine Fact, to accumulate in more than tolerable measure; whereupon said Governments were overset, and declared before all creatures to be too false.

For many, as Cranton tells us, and those very wise men, not now but long ago, have deplored the condition of human nature, esteeming life a punishment, and to be born a man the highest pitch of calamity; this, Aristotle tells us, Silenus declared when he was brought captive to Midas.

The worst is not ennui nor despair but their encounter, their collision. To be crushed between the two!

I plead guilty to valuing such a man beyond all other sorts of men. Smooth-shaven Respectabilities not a few one finds, that are not good for much. Small thanks to a man for keeping his hands clean, who would not touch the work but with gloves on!

Beauty is indeed a good gift of God; but that the good may not think it a great good, God dispenses it even to the wicked.

On reaching Athens he fell in with Antisthenes. Being repulsed by him, because he never welcomed pupils, by sheer persistence Diogenes wore him out. Once when he stretched out his staff against him, the pupil offered his head with the words, "Strike, for you will find no wood hard enough to keep me away from you, so long as I think you've something to say."

History shows that the thinkers who mounted on the top of the ladder of questions, who set their foot on the last rung, that of the absurd, have bequeathed to posterity only an example of sterility.

The class of big capitalists, who, in all civilized countries, are already in almost exclusive possession of all the means of subsistance and of the instruments (machines, factories) and materials necessary for the production of the means of subsistence. This is the bourgeois class, or the bourgeoisie.

You never know how much you really believe anything until its truth or falsehood becomes a matter of life and death to you. It is easy to you believe a rope to be strong and sound as long as you are merely using it to cord a box. But suppose that you had to hang by that rope over a precipice. Wouldn't you then first discover how much you really trusted it? ... Only a real risk tests the reality of a belief.

Of course, there are those - Sandel, Walzer and Dworkin, for example - who propose "communitarian" ways of thinking, as a further move in the direction which a sophisticated liberalism requires. But none of them is prepared to accept the real price of community: which is sanctity, intolerance, exclusion, and a sense that life's meaning depends upon obedience, and also on vigilance against the enemy.

The fact that goals may be dependent for their force on other more distant ends leads to the arrangement of these goals in a hierarchy - each level to be considered as an end relative to the levels below it and as a mean to the levels above it.

The state of health is a state of nonsensation, even of nonreality. As soon as we cease to suffer, we cease to exist.

Poems are magic ceremonies of language.

Cato instigated the magistrates to punish all offenders, saying that they that did not prevent crimes when they might, encouraged them. Of young men, he liked them that blushed better than those who looked pale.

To confuse our own constructions and inventions with eternal laws or divine decrees is one of the most fatal delusions of men. 

Very often the things that cost nothing cost us the most heavily; I can show you many objects the quest and acquisition of which have wrested freedom from our hands.

If we want eternal life, then we'll need to rewrite our bug-ridden genetic code and become god-like. "May all that have life be delivered from suffering", said Gautama Buddha. It's a wonderful sentiment. Sadly, only hi-tech solutions can ever eradicate suffering from the living world. Compassion alone is not enough.

It is in the gift for employing all the vicissitudes of life to one's own advantage and to that of one's craft that a large part of genius consists.

Let me never fall into the vulgar mistake of dreaming that I am persecuted whenever I am contradicted.

A ruddy drop of manly blood The surging sea outweighs, The world uncertain comes and goes; The lover rooted stays.

Brothers, love is a teacher; but one must know how to acquire it, for it is hard to acquire, it is dearly bought, it is won slowly by long labour. For we must love not only occasionally, for a moment, but for ever. Everyone can love occasionally, even the wicked can.

Neither of us cares a straw for popularity. A proof of this is for example, that, because of aversion to any personality cult, I have never permitted the numerous expressions of appreciation from various countries with which I was pestered during the existence of the International to reach the realm of publicity, and have never answered them, except occasionally by a rebuke. When Engels and I first joined the secret Communist Society we made it a condition that everything tending to encourage superstitious belief in authority was to be removed from the statutes.

For human beings, the measure of every action is the impression of the senses.

The real nature of the present revealed itself: it was what exists, all that was not present did not exist.

States are doomed when they are unable to distinguish good men from bad.

Morality is thus the relation of actions to the autonomy of the will, that is, to a possible giving of universal law through its maxims. An action that can coexist with the autonomy of the will is permitted; one that does not accord with it is forbidden. A will whose maxims necessarily harmonize with the laws of autonomy is a holy, absolutely good will. The dependence upon the principle of autonomy of a will that is not absolutely good (moral necessitation) is obligation. This, accordingly, cannot be attributed to a holy being. The objective of an action from obligation is called duty.

I do not, therefore, need any penetrating acuteness to see what I have to do in order that my volition be morally good. Inexperienced in the course of the world, incapable of being prepared for whatever might come to pass in it, I ask myself only: can you also will that your maxim become a universal law?

If we do not secure the foundation, we cannot secure the edifice.

Animals destitute of reason live with their own kind in a state of social amity. Elephants herd together; sheep and swine feed in flocks; cranes and crows take their flight in troops; storks have their public meetings to consult previously to their emigration, and feed their parents when unable to feed themselves; dolphins defend each other by mutual assistance; and everybody knows, that both ants and bees have respectively established by general agreement, a little friendly community.

Sovereignty, the freedom unto death, is threatening to a society that is organized around work and production.

Music is a hidden arithmetic exercise of the soul, which does not know that it is counting.
