All our knowledge falls with the bounds of experience.

Eternity is absence.

There is only one enduring happiness in life-to live for others.

After silence that which comes nearest to expressing the inexpressible is music.

During such calm sunshine of the mind, these spectres of false divinity never make their appearance.

It is only natural that I should constantly have revolved in my mind the question of the relationship of the symbolism of the unconscious to Christianity as well as to other religions. Not only do I leave the door open for the Christian message, but I consider it of central importance for Western man. It needs, however, to be seen in a new light, in accordance with the changes wrought by the contemporary spirit.

Nothing would prove more disastrous to our ideas, we contended, than to neglect the effect of the internal upon the external, of the psychological motives and needs upon existing institutions.

Saturninus said, "Comrades, you have lost a good captain to make him an ill general."

We know enough of our own history by now to be aware that people exploit what they have merely concluded to be of value, but they defend what they love. To defend what we love we need a particularizing language, for we love what we particularly know.

I frequently asked myself, if I could, or if I was bound to go on living, when life must be passed in this manner. I generally answered to myself, that I did not think I could possibly bear it beyond a year.

Dostoevsky once wrote: "If God did not exist, everything would be permitted"; and that, for existentialism, is the starting point. Everything is indeed permitted if God does not exist, and man is in consequence forlorn, for he cannot find anything to depend upon either within or outside himself. He discovers forthwith, that he is without excuse.

The word 'definition' has come to have a dangerously reassuring sound, owing no doubt to its frequent occurrence in logical and mathematical writings.

Value is not intrinsic, it is not in things. It is within us; it is the way in which man reacts to the conditions of his environment. Neither is value in words and doctrines, it is reflected in human conduct. It is not what a man or groups of men say about value that counts, but how they act.

The virtues are not poured into us, they are natural. Seek, and you will find them: neglect, and you will lose them.

Lay hold of today's task, and you will not need to depend so much upon tomorrow's. While we are postponing, life speeds by.

The guillotine takes life almost without touching the body, just as prison deprives of liberty or a fine reduces wealth. It is intended to apply the law not so to a real body capable of feeling pain as to a juridical subject, the possessor, among other rights, of the right to exist it had to have the abstraction of the law itself.

There is nothing in any object, consider'd in itself, which can afford us a reason for drawing a conclusion beyond it; even after the observation of the frequent or constant conjunction of objects, we have no reason to draw any inference concerning any object beyond those of which we have had experience.

The concept of guilt is found most powerfully developed even in the most primitive communal forms which we know: ... the man is guilty who violates one of the original laws which dominate the society and which are mostly derived from a divine founder; the boy who is accepted into the tribal community and learns its laws, which bind him thenceforth, learns to promise; this promise is often given under the sign of death, which is symbolically carried out on the boy, with a symbolical rebirth.

Capitalism has brought about the emancipation of collective humanity with respect to nature. But this collective humanity has itself taken on with respect to the individual the oppressive function formerly exercised by nature.

There is no good father who would want to resemble our Heavenly Father.

...no Monarchy limited or unlimited, nor any of the old Republics, can possibly be safe as long as this strange, nameless, wild, enthusiastic thing is established in the Center of Europe.

Where there is politics or economics, there is no morality.

If it were so, as conceited sagacity, proud of not being deceived, thinks, that we should believe nothing that we cannot see with our physical eyes, then we first and foremost ought to give up believing in love. ... We can be deceived by believing what is untrue, but we certainly are also deceived by not believing what is true. ... Which deception is more dangerous?

Let men be happy, informed, skillful, well behaved, and productive.

We hardly know any instance of the strength and weakness of human nature so striking, and so grotesque, as the character of this haughty, vigilant, resolute, sagacious blue-stocking, half Mithridates and half Trissotin, bearing up against a world in arms, with an ounce of poison in one pocket and a quire of bad verses in the other.

From a Darwinian point of view, human beliefs are adaptations to our part of the world. No doubt much of what we believe must be roughly accurate, or else we would not have survived. But the beliefs we have evolved might latch on to the world only enough to help us stumble our way through it, and then only for the time being. Human belief-systems could be useful illusions, appearing and disappearing as they prove to be more or less advantageous in the random walk of natural selection. Might not evolution be one of these illusions? Scientific naturalism is the theory that human beliefs are evolutionary adaptations whose survival has nothing to do with their truth. But in that case scientific naturalism is self-defeating, since on its own premises scientific theories cannot be known to be true.

A stupid man's report of what a clever man says is never accurate, because he unconsciously translates what he hears into something that he can understand.

To me, in these circumstances, that of "Hero-worship" becomes a fact inexpressibly precious; the most solacing fact one sees in the world at present. There is an everlasting hope in it for the management of the world. Had all traditions, arrangements, creeds, societies that men ever instituted, sunk away, this would remain. The certainty of Heroes being sent us; our faculty, our necessity, to reverence Heroes when sent: it shines like a polestar through smoke-clouds, dust-clouds, and all manner of down-rushing and conflagration.

Morality is the beauty of Philosophy.

I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary.

Where all think alike, no one thinks very much.

I must avert here once again to my view of the opposition that exists between individuality and personality, notwithstanding the fact that the one demands the other. Individuality is, if I may so express it, the container or thing which contains, personality the content or thing contained, or I might say that my personality is in a certain sense my comprehension, that which I comprehend or embrace within myself - which is in a certain way the whole Universe - and that my individuality is my extension; the one my infinite, the other my finite.

I have always thought that clarity is a form of courtesy that the philosopher owes; moreover, this discipline of ours considers it more truly a matter of honor today than ever before to be open to all minds ... This is different from the individual sciences which increasingly [interpose] between the treasure of their discoveries and the curiosity of the profane the tremendous dragon of their closed terminology.

"If God did not exist, he would have to be invented." But all nature cries aloud that he does exist: that there is a supreme intelligence, an immense power, an admirable order, and everything teaches us our own dependence on it.

It is best to bear what cannot be changed.

The love of power is a part of human nature, but power-philosophies are, in a certain precise sense, insane. The existence of the external world, both that of matter and of other human beings, is a datum, which may be humiliating to a certain kind of pride, but can only be denied by a madman. Men who allow their love of power to give them a distorted view of the world are to be found in every asylum: one man will think he is Governor of the Bank of England, another will think he is the King, and yet another will think he is God. Highly similar delusions, if expressed by educated men in obscure language, lead to professorships in philosophy; and if expressed by emotional men in eloquent language, lead to dictatorships. Certified lunatics are shut up because of the proneness to violence when their pretensions are questioned; the uncertified variety are given control of powerful armies, and can inflict death and disaster upon all sane men within their reach.

It is on account neither of God's weakness nor ignorance that evil comes into the world, but rather it is due to the order of his wisdom and the greatness of his goodness that diverse grades of goodness occur in things, many of which would be lacking if no evil were permitted. Indeed, the good of patience would not exist without the evil of persecution; nor the good of preservation of life in a lion if not for the evil of the destruction of the animals on which it lives.

To execute laws is a royal office; to execute orders is not to be a king. However, a political executive magistracy, though merely such, is a great trust.

Labor is a commodity, like any other, and its price is therefore determined by exactly the same laws that apply to other commodities. In a regime of big industry or of free competition - as we shall see, the two come to the same thing - the price of a commodity is, on the average, always equal to its cost of production. Hence, the price of labor is also equal to the cost of production of labor. But, the costs of production of labor consist of precisely the quantity of means of subsistence necessary to enable the worker to continue working, and to prevent the working class from dying out. The worker will therefore get no more for his labor than is necessary for this purpose; the price of labor, or the wage, will, in other words, be the lowest, the minimum, required for the maintenance of life.

He said they that were serious in ridiculous matters would be ridiculous in serious affairs.

I live from day to day, and content myself with having enough to meet my present and ordinary needs; for the extraordinary, all the provision in the world could not suffice.

We are obviously heading for revolution-something I have never once doubted since 1850. The first act will include a by no means gratifying rehash of the stupidities of '48-'49. However, that's how world history runs its course, and one has to take it as one finds it.

Human history is not the product of the wise direction of human reason, but is shaped by the forces of emotion-our dreams, our pride, our greed, our fears, and our desire for revenge.

A man discovers what he is actually worth in this world when he faces society as a man, without money, name, or powerful connections, stripped of all but his native potentialities. He soon finds that nothing has less weight than his human qualities. They are prized so low that the market does not even list them. Strict science, which acknowledges man only as a biological concept, reflects man's lot in the actual world; in himself, man is nothing more than a member of a species. In the eyes of the world, the quality of humanity confers no title to existence, nay, not even a right of sojourn. Such title must be certified by special social circumstances stipulated in documents to be presented on demand.

The only justifiable stopping place for the expansion of altruism is the point at which all whose welfare can be affected by our actions are included within the circle of altruism. This means that all beings with the capacity to feel pleasure or pain should be included; we can improve their welfare by increasing their pleasures and diminishing their pains.
