The anarchists put the thing upside down. They declare that the proletarian revolution must begin by doing away with the political organisation of the state. But after its victory the sole organisation which the proletariat finds already in existence is precisely the state. This state may require very considerable alterations before it can fulfil its new functions. But to destroy it at such a moment would be to destroy the only organism by means of which the victorious proletariat can assert its newly-conquered power, hold down its capitalist adversaries and carry out that economic revolution of society without which the whole victory must end in a new defeat and in a mass slaughter of the workers similar to those after the Paris Commune.

It is the duty of every man, so far as his ability extends, to detect and expose delusion and error.

The artist is the person who invents the means to bridge biological inheritance and the environments created by technological innovation.

Every person is an end in themselves. That's universal. To respect that leads to flourishing. Not respecting it in extremes leads to unnecessary death.

We do not directly go about the execution of the purpose that thrills us, but shut our doors behind us, and ramble with prepared minds, as if the half were already done. Our resolution is taking root or hold on the earth then, as seeds first send a shoot downward, which is fed by their own albumen, ere they send one upwards to the light.

To be taken without consent from my home and friends; to lose my liberty; to undergo all those assaults on my personality which modern psychotherapy knows how to deliver; to be re-made after some pattern of "normality" hatched in a Viennese laboratory to which I never professed allegiance; to know that this process will never end until either my captors have succeeded or I have grown wise enough to cheat them with apparent success-who cares whether this is called Punishment or not? "The Humanitarian Theory of Punishment"

Justice is the end of government. It is the end of civil society. It ever has been, and ever will be, pursued until it be obtained, or until liberty be lost in the pursuit.

Our moral virtues benefit mainly other people; intellectual virtues, on the other hand, benefit primarily ourselves; therefore the former make us universally popular, the latter unpopular.

What I have given in the second book on the nature and properties of curved lines, and the method of examining them, is, it seems to me, as far beyond the treatment in the ordinary geometry, as the rhetoric of Cicero is beyond the a, b, c of children.

The major and almost only theme of all my work is the struggle of man with "God": the unyielding, inextinguishable struggle of the naked worm called "man" against the terrifying power and darkness of the forces within him and around him.

Without disarmament there can be no lasting peace. On the contrary, the continuation of military armaments in their present extent will with certainty lead to new catastrophies...For the creation of this public opinion in favor of disarmament every person living shares the responsibility, through ever deed and every word.

Well, what does "good" mean anyway...? As Wittgenstein suggested, "good," like "game," has a family of meanings. Prominent among them is this one: "meets the criteria or standards of assessment or evaluation."

The pathfinders of modern thought did not derive what is good from the law. ... Their role in history was not that of adapting their words and actions to the text of old documents or generally accepted doctrines: they themselves created the documents and brought about the acceptance of their doctrines.

We are afraid of the enormity of the possible.

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.

The Mass is the greatest blasphemy of God, and the highest idolatry upon earth, an abomination the like of which has never been in Christendom since the time of the Apostles.

Observe, observe perpetually.

"New friends, however, will not be the same." No, nor will you yourself remain the same; you change with every day and every hour.

the ultimate end, with reference to and for the sake of which all other things are desirable...is an existence exempt as far as possible from pain, and as rich as possible in enjoyments...This, being, according to the utilitarian opinion, the end of human action, is necessarily also the standard of morality; which may accordingly be defined, the rules and precepts for human conduct, by the observance of which an existence such as has been described might be, to the greatest extent possible, secured to all mankind; and not to them only, but, so far as the nature of things admits, to the whole sentient creation.

For it is the same thing that can be thought and that can be.

I suddenly dreamt that I picked up the revolver and aimed it straight at my heart - my heart, and not my head; and I had determined beforehand to fire at my head, at my right temple. After aiming at my chest I waited a second or two, and suddenly my candle, my table, and the wall in front of me began moving and heaving. I made haste to pull the trigger.

Language steps in where the angels of experience fear to tread.

Marriage is for women the commonest mode of livelihood, and the total amount of undesired sex endured by women is probably greater in marriage than in prostitution.

Now why, if freedom is striven after for love of the I after all - why not choose the I himself as beginning, middle, and end?

The form most contradictory to human life that can appear among the human species is the "self-satisfied man."

All state obligations are against the conscience of a Christian: the oath of allegiance, taxes, law proceedings and military service.

It is hard to believe that this simple truth is not understood by those leaders who forbid their followers to use effective contraceptive methods. They express a preference for 'natural' methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.

This is that which I think great readers are apt to be mistaken in; those who have read of everything, are thought to understand everything too; but it is not always so. Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections ; unless we chew them over again, they will not give us strength and nourishment.

A geometrician has learned to perform the most difficult demonstrations and calculations, as a monkey has learned to take his little hat off and on...

Every great advance in science has issued from a new audacity of imagination.

The pursuit of philosophy is founded on the belief that knowledge is good, even if what is known is painful. A man imbued with the philosophic spirit, whether a professional philosopher or not, will wish his beliefs to be as true as he can make them, and will, in equal measure, love to know and hate to be in error. This principle has a wider scope than may be apparent at first sight.

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.

Of the evils most liable to attend on any sort of early proficiency, and which often fatally blights its promise, my father most anxiously guarded against. This was self-conceit. He kept me, with extreme vigilance, out of the way of hearing myself praised, or of being led to make self-flattering comparisons between myself and others. From his own intercourse with me I could derive none but a very humble opinion of myself; and the standard of comparison he always held up to me, was not what other people did, but what a man could and ought to do. He completely succeeded in preserving me from the sort of influences he so much dreaded. I was not at all aware that my attainments were anything unusual at my age.

There's a Bible on that shelf there. But I keep it next to Voltaire - poison and antidote.

An observer studying the Solar system dispassionately, and finding himself capable of bringing the four giant planets to his notice, could reasonably say that the Solar system consisted of one star, four planets, and some traces of debris.

It is impossible for someone to dispel his fears about the most important matters if he doesn't know the nature of the universe but still gives some credence to myths. So without the study of nature there is no enjoyment of pure pleasure.

The Idols of the Cave are the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others; or to the reading of books, and the authority of those whom he esteems and admires; or to the differences of impressions, accordingly as they take place in a mind preoccupied and predisposed or in a mind indifferent and settled; or the like. So that the spirit of man (according as it is meted out to different individuals) is in fact a thing variable and full of perturbation, and governed as it were by chance. Whence it was well observed by Heraclitus that men look for sciences in their own lesser worlds, and not in the greater or common world.

If the people are happy, united, wealthy, and powerful, we presume the rest. We conclude that to be good from whence good is derived.

It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox.

Practice yourself, for heaven's sake, in little things; and thence proceed to greater.

There is only one way to defeat the enemy, and that is to write as well as one can. The best argument is an undeniably good book.

It is unjust that the whole of society should contribute towards an expence of which the benefit is confined to a part of the society.

I decline the election. - It has ever been my rule through life, to observe a proportion between my efforts and my objects. I have never been remarkable for a bold, active, and sanguine pursuit of advantages that are personal to myself.

All mortals are equal; it is not their birth, But virtue itself that makes the difference.

I think the devil doesn't exist, but man has created him, he has created him in his own image and likeness.

Where men are the most sure and arrogant, they are commonly the most mistaken, and have there given reins to passion, without that proper deliberation and suspense, which can alone secure them from the grossest absurdities.

A definition may be very exact, and yet go but a very little way towards informing us of the nature of the thing defined.
