I do not believe in what is often called... 'exact terminology'... [or] in definitions... [they] do not... add to exactness... I especially dislike pretentious terminology and... pseudo-exactness concerned with it.

Those who were best able to provide themselves with the means of security against their neighbors, being thus in possession of the surest guarantee, passed the most agreeable life in each other's society; and their enjoyment of the fullest intimacy was such that, if one of them died before his time, the survivors did not mourn his death as if it called for sympathy.

It is because of my wretchedness that I am "I." It is on account of the wretchedness of the universe that, in a sense, God is "I" (that is to say a person).

I want to write - I want to write - I want to write and never never never will. I know it and I am so unhappy and it seems as though nothing else mattered. Whatever I'm doing, it's always there, an ultimate longing there saying, "Write this - write that - write -" and I can't. Lack ability, time, strength, and duration of vision. I wish someone would tell me brutally, "You can never write anything. Take up home gardening!"

I would say act like a man of thought and think like a man of action.

Few men have been admired by their own domestics.

Anyone can hold the helm when the sea is calm.

I write to thee on this subject, friend, because I am angry at a book which I have just left, which is so large, that it seems to contain universal science, but it hath almost split my head, without teaching me anything.

The dreamer must contaminate the others by his dream, he must make them fall into it.

To get to know a truth properly, one must polemicize it.

Man must be free of it all, of his bad conscience and of the bad salvation from this conscience in order to become in truth the way. Now, he no longer promises others the fulfillment of his duties, but promises himself the fulfillment of man.

The hand that rounded Peter's dome, And groined the aisles of Christian Rome, Wrought in a sad sincerity, Himself from God he could not free; He builded better than he knew, The conscious stone to beauty grew.

What I know at sixty, I knew as well at twenty. Forty years of a long, a superfluous, labor of verification.

There continue to be complex debates about what Nietzsche understood truth to be. Quite certainly, he did not think, in pragmatist spirit, that beliefs are true if they serve our interests or welfare: we have just seen some of his repeated denials of this idea. The more recently fashionable view is that he was the first of the deniers, thinking that there is no such thing as truth, or that truth is what anyone thinks it is, or that it is a boring category that we can do without. This is also wrong, and more deeply so. Nietzsche did not think that the ideal of truthfulness went into retirement when its metaphysical origins were discovered, and he did not suppose, either, that truthfulness could be detached from a concern for the truth. Truthfulness as an ideal retains its power, and so far from his seeing truth as dispensable or malleable, his main question is how it can be made bearable.

The circumstances of justice may be described as the normal conditions under which human cooperation is both possible and necessary.

Well, Prince, so Genoa and Lucca are now just family estates of the Buonapartes. But I warn you, if you don't tell me that this means war, if you still try to defend the infamies and horrors perpetrated by that Antichrist-I really believe he is Antichrist-I will have nothing more to do with you and you are no longer my friend, no longer my 'faithful slave,' as you call yourself! But how do you do? I see I have frightened you-sit down and tell me all the news.

There is one ethical principle, either you are preserving life generally, or you aren't. Preserving life in your ends and your means determines whether you are good or evil.

The days .... come and go like muffled and veiled figures, sent from a distant friendly party; but they say nothing, and if we do not use the gifts they bring, they carry them as silently away.

In the human reality, all existence that spends itself in procuring the prerequisites of existence is thus an "untrue" and unfree existence. Obviously this reflects the not at all ontological condition of a society based on the proposition that freedom is incompatible with the activity of procuring the necessities of life, that this activity is the "natural" function of a specific class, and that cognition of the truth and true existence imply freedom from the entire dimension of such activity. ... Society still is organized in such a way that procuring the necessities of life constitutes the full-time and life-long occupation of specific social classes, which are therefore unfree and prevented from a human existence. In this sense, the classical proposition according to which truth is incompatible with enslavement by socially necessary labor is still valid.

To understand how indirect communication is possible we must grasp what it is about ordinary communication that is being changed.

We are no nearer heaven on the top of Mount Cenis than at the bottom of the sea; take the distance with your astrolabe. They debase God even to the carnal knowledge of women, to so many times, and so many generations.

Human freedom is realised in the adoption of humanity as an end in itself, for the one thing that no-one can be compelled to do by another is to adopt a particular end.

You are in the same manner surrounded with a small circle of persons... full of desire. They demand of you the benefits of desire... You are therefore properly the king of desire. ...equal in this to the greatest kings of the earth... It is desire that constitutes their power; that is, the possession of things that men covet.

Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

To dissimulate is to pretend not to have what one has. To simulate is to feign to have what one doesn't have. One implies a presence, the other an absence. But it is more complicated than that because simulating is not pretending: "Whoever fakes an illness can simply stay in bed and make everyone believe he is ill. Whoever simulates an illness produces in himself some of the symptoms" (Littré). Therefore, pretending, or dissimulating, leaves the principle of reality intact: the difference is always clear, it is simply masked, whereas simulation threatens the difference between the "true" and the "false," the "real" and the "imaginary."

What is beginning to emerge, then, is a theory about psychic sensitivity. It runs as follows. When I relax deeply, it is as if someone opened up the partition between the two compartments of my brain, turning them into a single large room. I experience a sense of mental freedom as if I can suddenly breathe more deeply, and a feeling of contact with things. Everyone has had the experience of being in a state of hurry or excitement, and failing to notice that they have bruised or scratched themselves -- until the excitement evaporates and the pain makes itself known. Hurry and tension raise our sensitivity threshold, and at the same time, erect a glass wall between us and reality. In the "unicameral" state, this wall vanishes, and everything seems more real.

it is absurd ... to hope that maybe another Newton may some day arise, to make intelligible to us even the genesis of but a blade of grass

No punishment has ever possessed enough power of deterrence to prevent the commission of crimes. On the contrary, whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been.

There is no moral precept that does not have something inconvenient about it.

So to be patriots as not to forget we are gentlemen.

What chiefly diverts the men of democracies from lofty ambition is not the scantiness of their fortunes, but the vehemence of the exertions they daily make to improve them.

The blame rests with the government. Why do they not put adulterers to death? Then I would not need to give such advice. Between two evils one is always the lesser, in this case allowing the adulterer to remarry in a distant land in order to avoid fornication . . .

To him who looks upon the world rationally, the world in its turn presents a rational aspect. The relation is mutual.

Thus far, gentlemen, I have been insisting very strenuously upon what the most vulgar common sense has every disposition to assent to and only ingenious philosophers have been able to deceive themselves about. But now I come to a category which only a more refined form of common sense is prepared willingly to allow, the category which of the three is the chief burden of Hegel's song, a category toward which the studies of the new logico-mathematicians, Georg Cantor and the like, are steadily pointing, but to which no modern writer of any stripe, unless it be some obscure student like myself, has ever done anything approaching to justice.

From such honor and such a height of fortune am I, thus fallen to earth, cast down amongst mortals.

The principle of brotherhood expounded by the agitator of Nazareth preserved the germ of life, of truth and justice, so long as it was the beacon light of the few. The moment the majority seized upon it, that great principle became a shibboleth and harbinger of blood and fire, spreading suffering and disaster. The attack on the omnipotence of Rome was like a sunrise amid the darkness of the night, only so long as it was made by the colossal figures of a Huss, a Calvin, or a Luther. Yet when the mass joined in the procession against the Catholic monster, it was no less cruel, no less bloodthirsty than its enemy. Woe to the heretics, to the minority, who would not bow to its dicta. After infinite zeal, endurance, and sacrifice, the human mind is at last free from the religious phantom; the minority has gone on in pursuit of new conquests, and the majority is lagging behind, handicapped by truth grown false with age.

The heights of popularity and patriotism are still the beaten road to power and tyranny ; flattery to treachery ; standing armies to arbitrary government ; and the glory of God to the temporal interest of the clergy.

Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he, who is cruel to living creatures, cannot be a good man. Moreover, this compassion manifestly flows from the same source whence arise the virtues of justice and loving-kindness towards men.

Beware of thinkers whose minds function only when they are fueled by a quotation.

Most men have nothing in their heads but their physical needs; put them on a desert island with nothing to occupy their minds and they would go insane. They lack real motive. The curse of civilization is boredom.

Food probably has a very great influence on the condition of men. Wine exercises a more visible influence, food does it more slowly but perhaps just as surely. Who knows if a well-prepared soup was not responsible for the pneumatic pump or a poor one for a war?

Love is better than hate, because it brings harmony instead of conflict into the desires of the persons concerned. Two people between whom there is love succeed or fail together, but when two people hate each other the success of either is the failure of the other.

Kant speaks of the "thing-in-itself" (Ding an sich) in order to distinguish it from the "thing-for-us" (Ding fur uns), that is, as a "phenomenon." A thing-in-itself is that which is not approachable through experience as are the rocks, plants, and animals. Every thing-for-us is as a thing and also a thing-in-itself, which means that it is recognized absolutely withing the absolute knowledge of God. But not every thing-in-itself is also a thing-for-us: God, for instance, is a thing-in-itself, as Kant uses the word, according to the meaning of Christian theology.

How good is it to remember one's insignificance: that of a man among billions of men, of an animal amid billions of animals; and one's abode, the earth, a little grain of sand in comparison with Sirius and others, and one's life span in comparison with billions on billions of ages. There is only one significance, you are a worker. The assignment is inscribed in your reason and heart and expressed clearly and comprehensibly by the best among the beings similar to you. The reward for doing the assignment is immediately within you. But what the significance of the assignment is or of its completion, that you are not given to know, nor do you need to know it. It is good enough as it is. What else could you desire?

By creating the world market, big industry has already brought all the peoples of the Earth, and especially the civilized peoples, into such close relation with one another that none is independent of what happens to the others. Further, it has co-ordinated the social development of the civilized countries to such an extent that, in all of them, bourgeoisie and proletariat have become the decisive classes, and the struggle between them the great struggle of the day. It follows that the communist revolution will not merely be a national phenomenon but must take place simultaneously in all civilized countries.

[T]he infinite is in capacity. That, however, which is infinite in capacity is not to be assumed as that which is infinite in energy. ...[I]t has its being in capacity, and in division and diminution. ...[I]t is always possible to assume something beyond it. It does not, however, on this account surpass every definite magnitude; as in division it surpasses every definite magnitude, and will be less.

Existence is illusory and it is eternal.
