Exchange value forms the substance of money, and exchange value is wealth.

A new word is like a fresh seed sown on the ground of the discussion.

Certainly one may, with as much reason and decency, plead for murder, robbery, lewdness, and barbarity, as for this practice: They are not more contrary to the natural dictates of Conscience, and feelings of Humanity; nay, they are all comprehended in it.

Let the public good overcome all private and selfish regards of every kind and degree; though in truth, even private and selfish regards, and every man's own interest, will be best promoted by the preservation of peace.

We often attribute "understanding" and other cognitive predicates by metaphor and analogy to cars, adding machines, and other artifacts, but nothing is proved by such attributions.

Life, in that it is life, necessarily entails justice.

In my opinion, all things in nature occur mathematically.

As for me, I am deeply a democrat; this is why I am in no way a socialist. Democracy and socialism cannot go together. You can't have it both ways.

The state monopolizes violence by calling its critics "violent". [...] Hence, we should be wary about those who claim that violence is necessary to curb or check violence; those who praise the forces of law, including the police and the prisons, as the final arbiters. To oppose violence is to understand that violence does not always take the form of the blow.

I went to Salt Lake City and the Mormons tried to convert me, but when I found they forbade tea and tobacco I thought it was no religion for me.

To desire you to read my book over and mark all the corrections you would wish me to make...would oblige me greatly: I know how much I shall be benefitted and I shall at the same time preserve the pretious right of private judgement for the sake of which our forefathers kicked out the Pope and the Pretender. I believe you to be much more infalliable than the Pope, but as I am a Protestant my conscience makes me scruple to submit to any unscriptural authority.

Step back in time; look closely at the child in the very arms of his mother; see the external world reflected for the first time in the yet unclear mirror of his understanding; study the first examples which strike his eyes; listen to the first words which arouse within him the slumbering power of thought; watch the first struggles which he has to undergo; only then will you comprehend the source of his prejudices, the habits, and the passions which are to rule his life. The entire man, so to speak, comes fully formed in the wrappings of his cradle.

As the variable capital always stays in the hands of the capitalist in some form or other, it cannot be claimed in any way that it converts itself into revenue for anyone.

Democracy is the process by which people choose the man who'll get the blame.

...this Jewish doctrine of the primacy of economic values has found the widest acceptance and been most whole-heartedly acted upon. From America it has begun to infect the rest of the world. We may be pardoned for wishing that the Jews had remained not forty, but four thousand years in their repulsive wilderness.

It is ugly to be punishable, but there is no glory in punishing. Hence the double system of protection that justice has set up between itself and the punishment it imposes.

All those movements which took place in the fifteenth and sixteenth centuries and which had the Reformation as their main expression and result should be analyzed as a great crisis of the Western experience of subjectivity and a revolt against the kind of religious and moral power which gave form, during the Middle Ages, to this subjectivity. The need to take a direct part in spiritual life, in the work of salvation, in the truth which lies in the Book-all that was a struggle for a new subjectivity.

Everything that depends on the action of nature is by nature as good as it can be, and similarly everything that depends on art or any rational cause, and especially if it depends on the best of all causes. To entrust to chance what is greatest and most noble would be a very defective arrangement.

I'll know how to die with courage; that is easier than living.

When two do the same thing, it is not the same thing after all.

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.

But Hermotimus, the Colophonian, rendered more abundant what was formerly published by Eudoxus and Theætetus, and invented a multitude of elements, and wrote concerning some geometrical places. But Philippus the Mendæan, a disciple of Plato, and by him inflamed in the mathematical disciplines, both composed questions, according to the institutions of Plato, and proposed as the object of his enquiry whatever he thought conduced to the Platonic philosophy.

Where knowledge is a duty, ignorance is a crime. 

Not without reason did he who had the right to do so speak of the foolishness of the cross. Foolishness, without a doubt, foolishness. And the American humorist, Oliver Wendell Holmes, was not altogether wide of the mark in making one of the characters in his ingenious conversations say that he thought better of those who were confined in a lunatic asylum on account of religious mania than of those who, while professing the same religious principles, kept their wits and appeared to enjoy life very well outside the asylums. But those who are at large, are they not really, thanks to God, mad too? Are there not mild madnesses, which not only permit us to mix with our neighbors without danger to society, but which rather enable us to do so, for by means of them we are able to attribute a meaning and finality to life and society?

Better to be an animal than a man, an insect than an animal, a plant than an insect, and so on. Salvation? Whatever diminishes the kingdom of consciousness and compromises its supremacy.

Once the good man was dead, one wore his hat and another his sword as he had worn them, a third had himself barbered as he had, a fourth walked as he did, but the honest man that he was - nobody any longer wanted to be that.

Phenomenology is not a philosophy; it is a philosophical method, a tool. It is like an adjustable spanner that can be used for dismantling a refrigerator or a car, or used for hammering in nails, or even for knocking somebody out.

The plea of anger or of drunkenness - as having placed the criminal for the moment beyond the control of his reason - relieves him from the charge of premeditated and malicious intent; but a rational legislation will rather provide more severe than milder punishment for such cases, particularly if such a state of mind is habitual with the accused; for a single unlawful act may well constitute an exception from an otherwise blameless life. But a person who pleads, "I habitually get so angry or so drunk as not to be any longer master of my senses!" confesses thereby that he changes himself into a beast on a fixed principle, and that he is, therefore, not fit to live among rational beings.

To be in touch with senses and emotions beyond conquest is to enter the realm of the mysterious.

What can only be taught by the rod and with blows will not lead to much good; they will not remain pious any longer than the rod is behind them.

Lucid intervals and happy pauses.

Accordingly, time logically supposes a continuous range of intensity of feeling. It follows then, from the definition of continuity, that when any particular kind of feeling is present, an infinitesimal continuum of all feelings differing infinitesimally from that, is present.

The cravings of love and sex are met with absolute ignorance by the majority of parents, who consider it as something indecent and improper, something disgraceful, almost criminal, to be suppressed and fought like some terrible disease. The love and tender feelings in the young plant are turned into vulgarity and coarseness through the stupidity of those surrounding it, so that everything fine and beautiful is either crushed altogether or hidden in the innermost depths, as a great sin, that dares not face the light.

The fake love of ressentiment man offers no real help, since for his perverted sense of values, evils like "sickness" and "poverty" have become goods.

In Germany there is much complaining about my "eccentricities." But since it is not known where my center is, it won't be easy to find out where or when I have thus far been "eccentric." That I was a philologist, for example, meant that I was outside my center (which fortunately does not mean that I was a poor philologist). Likewise, I now regard my having been a Wagnerian as eccentric. It was a highly dangerous experiment; now that I know it did not ruin me, I also know what significance it had for me — it was the most severe test of my character.

You have just dined, and however scrupulously the slaughterhouse is concealed in the graceful distance of miles, there is complicity.

The heroes in paganism correspond exactly to the saints in popery, and holy dervises in MAHOMETANISM. The place of, HERCULES, THESEUS, HECTOR, ROMULUS, is now supplied by DOMINIC, FRANCIS, ANTHONY, and BENEDICT. Instead of the destruction of monsters, the subduing of tyrants, the defence of our native country; whippings and fastings, cowardice and humility, abject submission and slavish obedience, are become the means of obtaining celestial honours among mankind.

We may assume the superiority ceteris paribus [all things being equal] of the demonstration which derives from fewer postulates or hypotheses—in short from fewer premisses; for... given that all these are equally well known, where they are fewer knowledge will be more speedily acquired, and that is a desideratum. The argument implied in our contention that demonstration from fewer assumptions is superior may be set out in universal form...

God will look to every soul like its first love because He is its first love.

Men became scientific because they expected law in Nature; and they expected law in Nature because they believed in a Legislator.

Scientists try to eliminate their false theories, they try to let them die in their stead. The believer-whether animal or man-perishes with his false beliefs.

Every age has its own poetry; in every age the circumstances of history choose a nation, a race, a class to take up the torch by creating situations that can be expressed or transcended only through poetry.

The Outsider cannot accept life as it is, who cannot consider his own existence or anyone else's necessary. He sees 'too deep and too much'. It is still a question of self-expression.

At electric speed, all forms are pushed to the limits of their potential.

Classical political economy nearly touches the true relation of things, without, however,consciously formulating it. This it cannot so long as it sticks in its bourgeois skin.

Even the most wretched individual of our present society could not exist and develop without the cumulative social efforts of countless generations. Thus the individual, his freedom and reason, are the products of society, and not vice versa: society is not the product of individuals comprising it; and the higher, the more fully the individual is developed, the greater his freedom - and the more he is the product of society, the more does he receive from society and the greater his debt to it.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.

The aim of the book is to set a limit to thought, or rather - not to thought, but to the expression of thoughts: for in order to be able to set a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought). It will therefore only be in language that the limit can be set, and what lies on the other side of the limit will simply be nonsense.

Power and violence are opposites; where the one rules absolutely, the other is absent. Violence appears where power is in jeopardy, but left to its own course it ends in power's disappearance.
