To think is to run after insecurity, to be demoralized for grandiose trifles, to immure oneself in abstractions with a martyr's avidity, to hunt up complications the way others pursue collapse or gain. The thinker is by definition keen for torment.

In regard to man's final end, all the higher religions are in complete agreement. The purpose of human life is the discovery of Truth, the unitive knowledge of the Godhead. The degree to which this unitive knowledge is achieved here on earth determines the degree to which it will be enjoyed in the posthumous state. Contemplation of truth is the end, action the means.

If people would but understand that they are not the sons of some fatherland or other, nor of Governments, but are sons of God, and can therefore neither be slaves nor enemies one to another - those insane, unnecessary, worn-out, pernicious organizations called Governments, and all the sufferings, violations, humiliations and crimes which they occasion, would cease.

Those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.

What maintains the marriage and what is it? Only the knowledge of the hearts, that is its beginning and end.

As incompetent in life as in death, I loathe myself and in this loathing I dream of another life, another death. And for having sought to be a sage such as never was, I am only a madman among the mad.

Obey the voice at eve obeyed at prime.

The advantage of pure, and the disadvantage of impure air are experienced each time we breathe, and all who understand the causes of disease know that an impure atmosphere is most unfavourable to the enjoyment of health, and an efficient cause to shorten human existence within the natural life of man. It is therefore most desirable that decisive measures should be devised and generally adopted to ensure to all a pure atmosphere, in which to live during their lives.

Nowhere is there more constancy and more unanimity than among the French to subordinate that sex which they pretend to honor so highly.

Whatever happens, I cannot be a silent witness to murder or torture. Anyone who is a partner in this is a despicable individual. I am sorry I cannot be moderate about it...

It is wrong to think that belief in freedom always leads to victory; we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it. Poland fought for freedom as no other country did. The Czech nation was prepared to fight for its freedom in 1938; it was not lack of courage that sealed its fate. The Hungarian Revolution of 1956 - the work of young people with nothing to lose but their chains - triumphed and then ended in failure. ... Democracy and freedom do not guarantee the millennium. No, we do not choose political freedom because it promises us this or that. We choose it because it makes possible the only dignified form of human coexistence, the only form in which we can be fully responsible for ourselves. Whether we realize its possibilities depends on all kinds of things - and above all on ourselves.

"Do the Duty which lies nearest thee," which thou knowest to be a Duty! Thy second Duty will already have become clearer.

I believe that man is in the last resort so free a being that his right to be what he believes himself to be cannot be contested.

Consider how, even in the meanest sorts of Labour, the whole soul of a man is composed into a kind of real harmony, the instant he sets himself to work! Doubt, Desire, Sorrow, Remorse, Indignation, Despair itself, all these like helldogs lie beleaguering the soul of the poor dayworker, as of every man: but he bends himself with free valour against his task, and all these are stilled, all these shrink murmuring far off into their caves. The man is now a man. The blessed glow of Labour in him, is it not as purifying fire, wherein all poison is burnt up, and of sour smoke itself there is made bright blessed flame!

This [experimentation] is the custom-and properly so-in those sciences where mathematical demonstrations are applied to natural phenomena, as is seen in the case of perspective, astronomy, mechanics, music, and others where the principles, once established by well-chosen experiments, become the foundations of the entire superstructure.

Money is coined liberty, and so it is ten times dearer to the man who is deprived of freedom. If money is jingling in his pocket, he is half consoled, even though he cannot spend it. But money can always and everywhere be spent, and, moreover, forbidden fruit is sweetest of all.

Many words befall men, mean and noble alike; do not be astonished by them, nor allow yourself to be constrained. If a lie is told, bear with it gently. But whatever I tell you, let it be done completely. Let no one persuade you by word or deed to do or say whatever is not best for you.

Personally, people know themselves very poorly.

The cultural atmosphere of Russia in those years had an adolescent quality, common to all periods of revolution: the belief that life is just beginning, that the future is unlimited, and that mankind is no longer bound by the shackles of history.

Subject matters in general do not exist. There are no subject matters; no branches of learning-or, rather, of inquiry: there are only problems, and the urge to solve them.

Be attentive therefore, according to the instruction of the Gospel, to learn obedience from the lily and the bird. Be not affrighted, do no despair, when thou comparest thy life with these teachers. There is nothing to despair about, for indeed thou shalt learn from them; and the Gospel first comforts thee by telling thee that God is the God of patience, and then it adds: 'Thou shalt learn from the lilies and the birds, learn to be absolutely obedient like the lilies and the birds, learn not to serve two masters; for no man can serve two masters, he must either ... or.

All who delight in the pleasures of the belly, exceeding all measure in eating and drinking and love, find that the pleasures are brief and last but a short while-only so long as they are eating and drinking-but the pains that come after are many and endure. The longing for the same things keeps ever returning, and whenever the objects of one's desire are realized forthwith the pleasure vanishes, and one has no further use for them. The pleasure is brief, and once more the need for the same things returns.

Money is a crystal formed of necessity in the course of the exchanges, whereby different products of labour are practically equated to one another and thus by practice converted into commodities.

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.

If the immediate creator of the universe be he who is proclaimed by Moses, then we hold nobler beliefs concerning him, inasmuch as we consider him to be the master of all things in general, but that there are besides national gods who are subordinate to him and are like viceroys of a king, each administering separately his own province; and, moreover, we do not make him the sectional rival of the gods whose station is subordinate to his. But if Moses first pays honour to a sectional god, and then makes the lordship of the whole universe contrast with his power, then it is better to believe as we do, and to recognise the God of the All, though not without apprehending also the God of Moses; this is better, I say, than to honour one who has been assigned the lordship over a very small portion, instead of the creator of all things.

The rights and duties of man thus simplified, it seems almost impertinent to attempt to illustrate truths that appear so incontrovertible: yet such deeply rooted prejudices have clouded reason, and such spurious qualities have assumed the name of virtues, that it is necessary to pursue the course of reason as it has been perplexed and involved in error, by various adventitious circumstances, comparing the simple axiom with casual deviations.Men, in general, seem to employ their reason to justify prejudices, which they have imbibed, they cannot trace how, rather than to root them out. The mind must be strong that resolutely forms its own principles; for a kind of intellectual cowardice prevails which makes many men shrink from the task, or only do it by halves. Yet the imperfect conclusions thus drawn, are frequently very plausible, because they are built on partial experience, on just, though narrow, views.

Everywhere and always, since its very inception, Christianity has turned the earth into a vale of tears; always it has made of life a weak, diseased thing, always it has instilled fear in man, turning him into a dual being, whose life energies are spent in the struggle between body and soul. In decrying the body as something evil, the flesh as the tempter to everything that is sinful, man has mutilated his being in the vain attempt to keep his soul pure, while his body rotted away from the injuries and tortures inflicted upon it.The Christian religion and morality extols the glory of the Hereafter, and therefore remains indifferent to the horrors of the earth. Indeed, the idea of self-denial and of all that makes for pain and sorrow is its test of human worth, its passport to the entry into heaven.

There has never been any custom, however useless it may become with changing conditions, that isn't clung to desperately simply because it is something old and familiar.

Philosophers should consider the fact that the greatest happiness principle can easily be made an excuse for a benevolent dictatorship. We should replace it by a more modest and more realistic principle - the principle that the fight against avoidable misery should be a recognized aim of public policy, while the increase of happiness should be left, in the main, to private initiative.

The sad truth of the matter is that most evil is done by people who never made up their minds to be or do either evil or good.

Falling in love is the one illogical adventure, the one thing of which we are tempted to think as supernatural, in our trite and reasonable world. The effect is out of all proportion with the cause. Two persons, neither of them, it may be, very amiable or very beautiful, meet, speak a little, and look a little into each other's eyes. That has been done a dozen or so of times in the experience of either with no great result. But on this occasion all is different. They fall at once into that state in which another person becomes to us the very gist and centrepoint of God's creation, and demolishes our laborious theories with a smile; in which our ideas are so bound up with the one master-thought that even the trivial cares of our own person become so many acts of devotion, and the love of life itself is translated into a wish to remain in the same world with so precious and desirable a fellow-creature.

The light will not shame you, if it shows you your own ugliness, and that ugliness so offends you that you perceive the beauty of the light.

No concrete test of what is really true has ever been agreed upon.

As much in vain, perhaps, will they search ancient history for examples of the modern Slave-Trade. Too many nations enslaved the prisoners they took in war. But to go to nations with whom there is no war, who have no way provoked, without farther design of conquest, purely to catch inoffensive people, like wild beasts, for slaves, is an hight of outrage against Humanity and Justice, that seems left by Heathen nations to be practised by pretended Christians. How shameful are all attempts to colour and excuse it!

The heart of man is the place the devil dwells in; I feel sometimes a hell within myself.

Might is a fine thing, and useful for many purposes; for 'one goes further with a handful of might than with a bagful of right'. You long for freedom? You fools! If you took might, freedom would come of itself. See, he who has might 'stands above the law'. How does this prospect taste to you, you 'law-abiding' people? But you have no taste!

That's... the crisis. The number of liberal democracies measured by... Freedom House in its annual survey of freedom around the world has been in decline for 16 straight years, and the biggest declines recently have been in the two biggest liberal democracies, India and the United States. So... we're dealing with a big global problem.

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.

I want to be seen here in my simple, natural, ordinary fashion, without straining or artifice; for it is myself that I portray...I am myself the matter of my book. To the Reader

Poverty is a virtue which one can teach oneself.

It shews the anxiety of the great men who influenced the conduct of affairs at that great event, to make the Revolution a parent of settlement, and not a nursery of future revolutions.

Where knowledge is a duty, ignorance is a crime. 

It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.

To say that a life is grievable is to claim that a life, even before it is lost, is, or will be, worthy of being grieved on the occasion of its loss; the life has value in relation to mortality. One treats a person differently if one brings the sense of the grievability of the other to one's ethical bearing toward the other. If an other's loss would register as a loss, would be marked and mourned, and if the prospect of loss is feared, and precautions are thus taken to safeguard that life from harm or destruction, then our very ability to value and safeguard a life depends upon an ongoing sense of its grievability-the conjectured future of a life as an indefinite potential that would be mourned were it cut short or lost.

Unity is the great goal toward which humanity moves irresistibly. But it becomes fatal, destructive of the intelligence, the dignity, the well-being of individuals and peoples whenever it is formed without regard to liberty, either by violent means or under the authority of any theological, metaphysical, political, or even economic idea. That patriotism which tends toward unity without regard to liberty is an evil patriotism, always disastrous to the popular and real interests of the country it claims to exalt and serve. Often, without wishing to be so, it is a friend of reaction - an enemy of the revolution, i.e., the emancipation of nations and men.

Charity, by which God and neighbor are loved, is the most perfect friendship.

Most kings and priests have been despotic, and all religions have been riddled with superstition.

The idea of Christ is much older than Christianity.

So long as you are a slave to the opinions of the many you have not yet approached freedom or tasted its nectar...But I do not mean by this that we ought to be shameless before all men and to do what we ought not; but all that we refrain from and all that we do, let us not do or refrain from merely because it seems to the multitude somehow honorable or base, but because it is forbidden by reason and the god within us.

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.
