Nothing is rich but the inexhaustible wealth of Nature. She shows us only surfaces, but she is million fathoms deep.

Put down all banks, admit none but a metallic circulation that will take its proper level with the like circulation in other countries, and then our manufacturers may work in fair competition with those of other countries, and the import duties which the government may lay for the purposes of revenue will so far place them above equal competition.

Appearances to the mind are of four kinds. Things either are what they appear to be; or they neither are, nor appear to be; or they are, and do not appear to be; or they are not, and yet appear to be. Rightly to aim in all these cases is the wise man's task.

By capitulating to life, this world has betrayed nothingness. . . . I resign from movement, and from my dreams. Absence! You shall be my sole glory. . . . Let "desire" be forever stricken from the dictionary, and from the soul! I retreat before the dizzying farce of tomorrows. And if I still cling to a few hopes, I have lost forever the faculty of hoping.

For this is our central human problem: that we are almost constantly the victims of our emotions, always being swept up and down on a kind of inner-switchback. We possess a certain control over them; we can 'direct our thoughts' -- or feelings -- in such a way as to intensify them. This is certainly our most remarkable human characteristic: imagination. Animals require actual physical stimuli to trigger their experience. A man can retreat into a book -- or a daydream -- and live through certain experiences quite independent of the physical world. He can even, for example, imagine a sexual encounter, and not only experience all the appropriate physical responses, but even the sexual climax. Such a curious ability is far beyond the power of any animal.

There is no more miserable human being than one in whom nothing is habitual but indecision.

A jealous lover of human liberty, deeming it the absolute condition of all that we admire and respect in humanity, I reverse the phrase of Voltaire, and say that, if God really existed, it would be necessary to abolish him. Ch. II; Variants or variant translations of this statement have also been attributed to Bakunin: The first revolt is against the supreme tyranny of theology, of the phantom of God. As long as we have a master in heaven, we will be slaves on earth. A boss in Heaven is the best excuse for a boss on earth, therefore If God did exist, he would have to be abolished.

People talk sometimes of bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel.

There is the world for you. Beauty, true beauty, is intangible. It is in the eye of the beholder. Something that we can lose at any moment, and the more you examine it, the more illusive it becomes. True happiness is virtue, and virtue is predicated on knowledge and righteous conduct.

I would have written a shorter letter, but I did not have the time.

An untempted woman cannot boast of her chastity.

When we rise out of the night into the new life and there begin to receive the signs, what can we know of that which - of him who gives them to us? Only what we experience from time to time from the signs themselves. If we name the speaker of this speech God, then it is always the God of a moment, a moment God.

Deem not life a thing of consequence. For look at the yawning void of the future, and at that other limitless space, the past.

Big industry, competition and generally the individualistic organization of production have become a fetter which it must and will shatter.

Belief in God and a future life makes it possible to go through life with less of stoic courage than is needed by skeptics. A great many young people lose faith in these dogmas at an age at which despair is easy, and thus have to face a much more intense unhappiness than that which falls to the lot of those who have never had a religious upbringing. Christianity offers reasons for not fearing death or the universe, and in so doing it fails to teach adequately the virtue of courage. The craving for religious faith being largely an outcome of fear, the advocates of faith tend to think that certain kinds of fear are not to be deprecated. In this, to my mind, they are gravely mistaken. To allow oneself to entertain pleasant beliefs as a means of avoiding fear is not to live in the best way. In so far as religion makes its appeal to fear, it is lowering to human dignity.

Concern for the symbol has completely disappeared from our science. And yet, if one were to give oneself the trouble, one could easily find, in certain parts at least of contemporary mathematics... symbols as clear, as beautiful, and as full of spiritual meaning as that of the circle and mediation. From modern thought to ancient wisdom the path would be short and direct, if one cared to take it.

Justice is itself the great standing policy of civil society; and any eminent departure from it, under any circumstances, lies under the suspicion of being no policy at all.

Beauty is merciless. You do not look at it, it looks at you and does not forgive.

That man lives badly who does not know how to die well.

Out of special hatred for our faith, the devil has sent some whores here to destroy our poor young men . . . such a syphilitic whore can poison ten, twenty, thirty or more of the children of good people, and thus is to be considered a murderer, or worse, as a poisoner.

It requires wisdom to understand wisdom: the music is nothing if the audience is deaf.

It is the greatest of all mistakes to do nothing because you can only do little.

A man who is free is like a mangy sheep in a herd. He will contaminate my entire kingdom and ruin my work.

Underlying the concept of positivity is the conviction that the positive is intrinsically positive in itself, without anyone pausing to ask what is to be regarded as positive. ... It is significant and really quite interesting that the term 'positive' actually contains this ambivalence. On the one hand, 'positive' means what is given, is postulated, is there-as when we speak of positivism as the philosophy that sticks to the facts. But, equally, 'positive' also refers to the good, the approvable, in a certain sense, the ideal. And I imagine that this semantic constellation expresses with precision what countless people actually feel to be the case.

Repent: for the kingdom of heaven is at hand.

Man has ever expressed some symbolical Philosophy of his Being in his Works and Conduct; he announces himself and his Gospel of Nature; he is the Messiah of Nature.

We are speaking on this occasion, not as members of this or that nation, continent, or creed, but as human beings, members of the species Man, whose continued existence is in doubt.

What is it, in your opinion, to be a great nobleman? It is to be master of several objects that men covet, and thus to be able to satisfy the wants and the desires of many. It is these wants and these desires that attract them towards you, and that make them submit to you: were it not for these, they would not even look at you; but they hope, by these services... to obtain from you some part of the good which they desire, and of which they see that you have the disposal.

I shall need only myself to be happy.

We were ensnared by the wisdom of the serpent; we are set free by the foolishness of God.

A conception of justice cannot be deduced from self evident premises or conditions on principles; instead, its justification is a matter of the mutual support of many considerations, of everything fitted together into one coherent view.

To conceive a thought - just one, but one that would tear the universe to pieces.

The universal basis of co-operation is the proportioning of benefits received to services rendered.

What else is the help of medicine than love?

It cannot but happen that those individuals whose functions are most out of equilibrium with the modified aggregate of external forces, will be those to die; and that those will survive whose functions happen to be most nearly in equilibrium with the modified aggregate of external forces. But this survival of the fittest, implies multiplication of the fittest. Out of the fittest thus multiplied, there will, as before, be an overthrowing of the moving equilibrium wherever it presents the least opposing force to the new incident force.

And we cannot change this order of things; but what we can do is to acquire stout hearts, worthy of good men, thereby courageously enduring chance and placing ourselves in harmony with Nature.

Permanent mass unemployment destroys the moral foundations of the social order. The young people, who, having finished their training for work, are forced to remain idle, are the ferment out of which the most radical political movements are formed. In their ranks the soldiers of the coming revolutions are recruited.

As a rule there are in everyone all sorts of good ideas, ready like tinder. But much of this tinder catches fire, or catches it successfully, only when it meets some flame or spark from outside, i.e. from some other person. Often, too, our own light goes out, and is rekindled by some experience we go through with a fellow-man. Thus we have each of us cause to think with deep gratitude of those who have lighted the flames within us.

Human beings can lose their lives in libraries. They ought to be warned.

Classical science was based upon the belief that it is possible to formulate both the position and velocity at one time of any given particle. It followed that knowledge of the position and velocity of a given number of particles would enable the future behavior of the whole collection to be accurately predicted. The principle of Heisenberg is that given the determination of position, its velocity can be stated only as of a certain order of probability, while if its velocity is determined the correlative factor of position can be stated only as of a certain order of probability. Both cannot be determined at once, from which it follows necessarily that the future of the whole collection cannot possibly be foretold except in terms of some order of probability.

Bereavement is a darkness impenetrable to the imagination of the unbereaved.

No man has ever been so far advanced by Fortune that she did not threaten him as greatly as she had previously indulged him.

The same man who could not find it in his conscience to curb his curiosity into the nuclear studies that might someday kill half of Earth would risk his life to save that of an unimportant fellow man.

His Religion is not an easy one: with rigorous fasts, lavations, strict complex formulas, prayers five times a day, and abstinence from wine, it did not "succeed by being an easy religion." As if indeed any religion, or cause holding of religion, could succeed by that! It is a calumny on men to say that they are roused to heroic action by ease, hope of pleasure, recompense, - sugar-plums of any kind, in this world or the next! In the meanest mortal there lies something nobler.

Though the framework is libertarian and laissez-faire, individual communities within it need not be, and perhaps no community within it will choose to be so. Thus, the characteristics of the framework need not pervade the individual communities. In this laissez-faire system it could turn out that though they are permitted, there are no actually functioning "capitalist" institutions; or that some communities have them and others don't or some communities have some of them, or what you will.

The more the concept of reason becomes emasculated, the more easily it lends itself to ideological manipulation and to propagation of even the most blatant lies. ... Subjective reason conforms to anything.

In contemplating thyself never include the vessel which surrounds thee, and these instruments which are attached about it. For they are like an ax, differing only in this, that they grow to the body. For indeed there is no more use in these parts without the cause which moves and checks them than in the weaver's shuttle, and the writer's pen, and the driver's whip.

People are scarcely aware that it is a slavery they are creating; they forget this in their zeal to make people free by overthrowing dominions. They are scarcely aware that it is slavery; how could it be possible to be a slave in relation to equals?

The thesis of the identity of concept and thing is in general the vital nerve of idealist thought, and indeed traditional thought in general. ... Negative dialectics as critique means above all criticism of precisely this claim to identity.
