I have never seen a class so deeply demoralised, so incurably debased by selfishness, so corroded within, so incapable of progress, as the English bourgeoisie; and I mean by this, especially the bourgeoisie proper, particularly the Liberal, Corn Law repealing bourgeoisie. For it nothing exists in this world, except for the sake of money, itself not excluded. It knows no bliss save that of rapid gain, no pain save that of losing gold. In the presence of this avarice and lust of gain, it is not possible for a single human sentiment or opinion to remain untainted.

It is unjust to call imaginary the diseases which are, on the contrary, only too real, since they proceed from our mind, the only regulator of our equilibrium and our health.

Let us speak plainly: everything which keeps us from self-dissolution, every lie which protects us against our unbreathable certitudes is religious.

Nobody can doubt that the entire range of applied science contributes to the very format of a newspaper. But the headline is a feature which began with the Napoleonic Wars. The headline is a primitive shout of rage, triumph, fear, or warning, and newspapers have thrived on wars ever since.

Some impose upon the world that they believe that which they do not; others, more in number, make themselves believe that they believe, not being able to penetrate into what it is to believe.

I deny that anyone knows, or can know, the nature of the two sexes, as long as they have only been seen in their present relation to one another. If men had ever been found in society without women, or women without men, or if there had been a society of men and women in which the women were not under the control of the men, something might have been positively known about the mental and moral differences which may be inherent in the nature of each. What is now called the nature of women is an eminently artificial thing - the result of forced repression in some directions, unnatural stimulation in others.

If now I...say "Stealing money is wrong," I produce a sentence which has no factual meaning - that is, expresses no proposition which can be either true or false. It is as if I had written "Stealing money!!" - where the shape and thickness of the exclamation marks show, by a suitable convention, that a special sort of moral disapproval is the feeling which is being expressed.

Tragic paradox of freedom: the mediocre men who alone make its exercise possible cannot guarantee its duration.

If a person loves only one other person and is indifferent to all others, his love is not love but a symbiotic attachment, or an enlarged egotism.

Men seem to pursue honour in order that they may believe themselves to be good. Accordingly, they seek to be honoured by the wise, and by those who know them well, and on the score of virtue; it is clear, therefore, that in their opinion at any rate, virtue is superior to honour. Perhaps, then, one ought to say that virtue rather than honour is the end of the political life; yet even virtue is plainly too imperfect: for it seems that a man might have all the virtues and yet be asleep, or fail to achieve anything all his life; moreover, such a person may suffer the greatest evils and misfortunes. And no one, in this case, would call a man, who passed his life in this manner, happy, except for argument's sake.

The artist reconstructs the world to his plan.

...out of the tomb of the murdered Monarchy in France, has arisen a vast, tremendous, unformed spectre, in a far more terrific guise than any which ever yet have overpowered the imagination and subdued the fortitude of man.

If we owe to it [civil society] any duty, it is not subject to our will. Duties are not voluntary. Duty and will are even contradictory terms. Now though civil society might be at first a voluntary act (which in many cases it undoubtedly was) its continuance is under a permanent standing covenant, coexisting with the society; and it attaches upon every individual of that society, without any formal act of his own. This is warranted by the general practice, arising out of the general sense of mankind.

As a human being it is just my nature to enjoy and share philosophy. I do this in the same way that some birds are eagles and some doves, some flowers lilies and some roses.

Constitutional freedom, as the right of every citizen to have to obey no other law than that to which he has given his consent or approval.

But the truth is that my work - I was going to say my mission - is to shatter the faith of men here, there, and everywhere, faith in affirmation, faith in negation, and faith in abstention in faith, and this for the sake of faith in faith itself; it is to war against all those who submit, whether it be to Catholicism, or to rationalism, or to agnosticism; it is to make all men live the life of inquietude and passionate desire.

Men are by nature merely indifferent to one another; but women are by nature enemies.

History proves nothing because it contains everything.

Thus every action must be due to one or other of seven causes: chance, nature, compulsion, habit, reasoning, anger, or appetite.

Amidst our greatest happiness someone within us cries out: "I am in pain! I want to escape your happiness! I am stifling!" Amidst our deepest despair someone within us cries out: "I do not despair! I fight on! I grasp at your head, I unsheathe myself from your body, I detach myself from the earth, I cannot be contained in brains, in names, in deeds!"

Prosperity makes friends, adversity tries them.

Even the most inspired verse, which boasts not without a relative justification to be immortal, becomes in the course of ages a scarcely legible hieroglyphic; the language it was written in dies, a learned education and an imaginative effort are requisite to catch even a vestige of its original force. Nothing is so irrevocable as mind.

America is like a large, friendly dog in a very small room. Every time it wags its tail, it knocks over a chair!

Rhetoric is the counterpart of Dialectic. Both alike are concerned with such things as come, more or less, within the general ken of all men and belong to no definite science. Accordingly, all men make use, more or less, of both; for to a certain extent all men attempt to discuss statements and to maintain them, to defend themselves and to attack others.

Man... whatever the origin of his soul, if it is pure, noble, and lofty, it is a beautiful soul which dignifies the man endowed with it.

If we want a theory explaining how people play billiards, we do not want a theory of perfect billiard balls; we want a theory of what heuristics a human billiard player uses in order to plan and make a (often not quite accurate) shot. These heuristics and actions do not involve solving the differential equations of the billiard board; they involve rules of thumb and it is these practice guides to action we are trying to discover in order to explain the behavior.

Human or general needs can be satisfied through society; for satisfaction of unique needs you must do some seeking. A friend and a friendly service, or even an individual's service, society cannot procure you. And yet you will every moment be in need of such a service, and on the slightest occasions require somebody who is helpful to you. Therefore do not rely on society, but see to it that you have the wherewithal to - purchase the fulfilment of your wishes.

All the world knows me in my book, and my book in me.

There was a brief moment after 9/11 when Colin Powell said "we should not rush to satisfy the desire for revenge." It was a great moment, an extraordinary moment, because what he was actually asking people to do was to stay with a sense of grief, mournfulness, and vulnerability.

Now, apparently, many men are again feeling homesick for the herd. They devote themselves passionately to whatever there is left in them of the sheep. They want to march through life together, along the collective path, shoulder to shoulder, wool rubbing wool, and the head down. This is the reason why so many European peoples are looking for a shepherd and a sheep dog.

No carelessness in your actions. No confusion in your words. No imprecision in your thoughts. (Hays translation) Be not careless in deeds, nor confused in words, nor rambling in thought.

Everything that happens is either endurable or not. If it's endurable, then endure it. Stop complaining. If it's unendurable . . . then stop complaining. Your destruction will mean its end as well.

There's no objective morality, but that's not the real point. It's not the point that morality has to somehow be a stone, or something that can be touched. 

The options that are available to choose are determined to a point, and this is the objective aspect of morality, ethics, goodness, fairness, justice. 

The subjective aspect can still remain subjective, but that doesn't mean goodness is relative.....at all. The measure of a man is a man.

Undeterred by this examination, the French Revolution gave rise to ideas which led beyond the ideas of the entire old world order. The revolutionary movement which began in 1789 in the Cercle Social, which in the middle of its course had as its chief representatives Leclerc and Roux, and which finally with Babeuf's conspiracy was temporarily defeated, gave rise to the communist idea which Babeuf's friend Buonarroti re-introduced in France after the Revolution of 1830. This idea, consistently developed, is the idea of the new world order.

A man should build a house with his own hands before he calls himself an engineer.

Martyrs create faith, faith does not create martyrs.

The principal means of realizing it will be the formation of an alliance between philosophers and the working classes, for which both are alike prepared by the negative and positive progress of the last five centuries. The direct object of their combined action will be to set in motion the force of Public Opinion.

There is but one truly serious philosophical problem and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy. All the rest, whether or not the world has three dimensions, whether the mind has nine or twelve categories comes afterwards. These are games; one must first answer. And if it is true, as Nietzsche claims, that a philosopher, to deserve our respect, must preach by example, you can appreciate the importance of that reply, for it will precede the definitive act. These are facts the heart can feel; yet they call for careful study before they become clear to the intellect. If I ask myself how to judge that this question is more urgent than that, I reply that one judges by the actions it entails. I have never seen anyone die for the ontological argument. 

Whereas materialistic historians and philosophers neglect psychic realities, Freud is inclined to overstress their importance. I am not a psychologist, but it seems to me fairly evident that physiological factors, especially our endocrines, control our destiny ... I am not able to venture a judgment on so important a phase of modern thought. However, it seems to me that psychoanalysis is not always salutary. It may not always be helpful to delve into the subconscious. The machinery of our legs is controlled by a hundred different muscles. Do you think it would help us to walk if we analyzed our legs and knew exactly which one of the little muscles must be employed in locomotion and the order in which they work? ... I am not prepared to accept all his [Freud's] conclusions, but I consider his work an immensely valuable contribution to the science of human behavior. I think he is even greater as a writer than as a psychologist. Freud's brilliant style is unsurpassed by anyone since Schopenhauer.

People talk sometimes of a 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. The tiger only tears and gnaws, that's all he can do. He would never think of nailing people by the ears, even if he were able to do it.

Consider thyself to be dead, and to have completed thy life up to the present time; and live according to nature the remainder which is allowed thee. Variant: Think of yourself as dead. You have lived your life. Now, take what's left and live it properly.

The more rational statement is that we feel sorry because we cry, angry because we strike, afraid because we tremble, and not that we cry, strike, or tremble, because we are sorry, angry, or fearful, as the case may be. Without the bodily states following on the perception, the latter would be purely cognitive in form, pale, colorless, destitute of emotional warmth.

A theologian is born by living, nay dying and being damned, not by thinking, reading, or speculating.
