A true friend will partake of the wants and sorrows of his friend, as if they were his own; if he be in want, he will relieve him; if he be in prison, he will visit him; if he be sick, he will come to him; nay-situations may occur, in which he would not scruple to die for him. It cannot then be doubted, that friendship is one of the most useful means of procuring a secure, tranquil, and happy life.

I pride myself on my capacity to perceive the transitory character of everything. An odd gift which has spoiled all my joys; better: all my sensations.

To a lesser degree, a secret ressentiment underlies every way of thinking which attributes creative power to mere negation and criticism. Thus modern philosophy is deeply penetrated by a whole type of thinking which is nourished by ressentiment. I am referring to the view that the "true" and the "given" is not that which is self-evident, but rather that which is "indubitable" or "incontestable," which can be maintained against doubt and criticism.

Sometimes, because my position has not been made clear enough, people think I'm a sort of radical anarchist who has an absolute hatred of power. No! What I am trying to do is to approach this extremely important and tangled phenomenon in our society, the exercise of power, with the most reflective, and I would say prudent attitude. Prudent in my analysis, in the moral and theoretical postulates I use: I try to figure out what's at stake. But to question the relations of power in the most scrupulous and attentive manner possible, looking into all the domains of its exercise, that's not the same thing as constructing a mythology of power as the beast of the apocalypse.

The capitalist cannot store labour-power in warehouses after he has bought it, as he may do with the raw material.

The kind of equality utilitarianism supports is given by Bentham's formula...: 'everybody to count for one, and nobody for more than one'...Utilitarianism seeks to maximize happiness, and in deciding how to calculate whether happiness is being maximized, no one's pleasures or pains should count for less because they are peasants rather than aristocrats, slaves rather than slave-owners, Africans rather than Europeans, poor rather than rich, illiterates rather than doctors of philosophy, children rather than adults, females rather than males, or even, as we have seen, non-human animals rather than human beings.

It belongs to the self-respect of intellect to pursue every tangle of thought to its final unravelment.

Who can exhaust a man? Who knows a man's resources?

We are not ostriches, and cannot believe that if we refuse to look at what we do not wish to see, it will not exist. This is especially the case when what we do not wish to see is what we wish to eat. If it were really indispensable, or, if not indispensable, at least in some way useful! But it is quite unnecessary ... And this is continually being confirmed by the fact that young, kind, undepraved people - especially women and girls - without knowing how it logically follows, feel that virtue is incompatible with beefsteaks, and, as soon as they wish to be good, give up eating flesh.

Commit no lustfulness, so that harm and regret may not reach thee from thine own actions.

The difference between the first- and second-best things in art absolutely seems to escape verbal definition - it is a matter of a hair, a shade, an inward quiver of some kind - yet what miles away in the point of preciousness!

There are two kinds of truths: those of reasoning and those of fact. The truths of reasoning are necessary and their opposite is impossible; the truths of fact are contingent and their opposites are possible.

The invasion... exhibits in stark terms, the choice that is before us today between maintaining a liberal government that respects the rights of individuals, or moving over to a form of centralized illiberal dictatorship, even if that... illiberal government is somehow democratically legitimated. ...That's the central issue in global politics today. ...That's basically what the... Ukraine invasion is about, and that's why... all liberal societies that care about those individual freedoms... have a very powerful interest in the outcome of that war, because Putin and Russia are at the center of an international network of illiberal forces that are seeking to overturn liberal values in virtually every part of the world, and therefore... that's all part of a larger global struggle over our fundamental liberal values.

The most thought provoking thing in our thought provoking time is that we are still not thinking.

When Socrates and his two great disciples composed a system of rational ethics they were hardly proposing practical legislation for mankind...They were merely writing an eloquent epitaph for their country.

Another force driving progressive evolution is the so-called "arms-race." Prey animals evolve faster running speeds because predators do. Consequently predators have to evolve even faster running speeds, and so on, in an escalating spiral. Such arms races probably account for the spectacularly advanced engineering of eyes, ears, brains, bat "radar" and all the other high-tech weaponry that animals display.

The poet presents the imagination with images from life and human characters and situations, sets them all in motion and leaves it to the beholder to let these images take his thoughts as far as his mental powers will permit. This is why he is able to engage men of the most differing capabilities, indeed fools and sages together. The philosopher, on the other hand, presents not life itself but the finished thoughts which he has abstracted from it and then demands that the reader should think precisely as, and precisely as far as, he himself thinks. That is why his public is so small.

We shall either learn to know a Hero, a true Governor and Captain, somewhat better, when we see him; or else go on to be forever governed by the Unheroic;-had we ballot-boxes clattering at every street-corner, there were no remedy in these.

The question of the principle of the form of the intelligible world turns, therefore, upon making apparent in what manner it is possible for several substances to be in mutual commerce, and for this reason to pertain to the same whole, which is called world. We do not here consider the world, let it be understood, as to matter, that is, as to the nature of the substances of which it consists, whether they be material or immaterial, but as to form, that is to say, how among several things taken separately a connection, and among them all, totality can have place.

Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves.

Artist and perceiver alike begin with what may be called a total seizure, an inclusive qualitative whole not yet articulated, not distinguished into members.

To throw oneself into strange teachings is quite dangerous.

The ego involved in responsibility is me and no one else, me with whom one whould have liked to pair up a sister soul, from whom one would have substitution and sacrifice.

Temperance is that discreet regulation of the desires and passions, by which we are enabled to enjoy pleasures without suffering any consequent inconvenience. They who maintain such a constant self-command, as never to be enticed by the prospect of present indulgence, to do that which will be productive of evil, obtain the truest pleasure by declining pleasure.

I pray you, magnificent Sir, do not trouble yourself to return to us, but await our coming to you.

The tool, as we have seen, is not exterminated by the machine.

Children have as much mind to shew that they are free, that their own good actions come from themselves, that they are absolute and independent, as any of the proudest of you grown men, think of them as you please.

The student of mathematics often finds it hard to throw off the uncomfortable feeling that his science, in the person of his pencil, surpasses him in intelligence,-an impression which the great Euler confessed he often could not get rid of. This feeling finds a sort of justification when we reflect that the majority of the ideas we deal with were conceived by others, often centuries ago. In a great measure it is really the intelligence of other people that confronts us in science.

Man has an invincible inclination to allow himself to be deceived and is, as it were, enchanted with happiness when the rhapsodist tells him epic fables as if they were true, or when the actor in the theater acts more royally than any real king. So long as it is able to deceive without injuring, that master of deception, the intellect, is free; it is released from its former slavery and celebrates its Saturnalia. It is never more luxuriant, richer, prouder, more clever and more daring.

It is difficult to walk at one and the same time many paths of life.

The best doctor is the one you run for and can't find.

The relation of feeling toward art and its bringing-forth can be one of production or one of reception and enjoyment.

The will of man has no power whatever over his opinions; he must, and ever did, and ever will, believe what has been, is, or may be impressed on his mind by his predecessors, and the circumstances which surround him.

So far no one had had enough courage and intelligence to reveal me to my dear Germans. My problems are new, my psychological horizon frighteningly comprehensive, my language bold and clear; there may well be no books written in German which are richer in ideas and more independent than mine.

Unlike private enterprise which quickly modifies its actions to meet emergencies - unlike the shopkeeper who promptly finds the wherewith to satisfy a sudden demand - unlike the railway company which doubles its trains to carry a special influx of passengers; the law-made instrumentality lumbers on under all varieties of circumstances at its habitual rate. By its very nature it is fitted only for average requirements, and inevitably fails under unusual requirements.

Philosophy and religion are enemies, and because they are enemies they have need of one another. There is no religion without some philosophical basis, no philosophy without roots in religion. ... the attacks which are directed against religion from a presumed scientific or philosophical point of view are merely attacks from another but opposing religious point of view.

The evident justice and utility of the foregoing maxims have recommended them more or less to the attention of all nations.

We find that everything that makes up difference and number is pure accident, pure show, pure constitution. Every production, of whatever kind, is an alteration, but the substance remains always the same, because it is only one, one divine immortal being.

Science is a cemetery of dead ideas, even though life may issue from them.

The old Romans had a custom which survived even into my lifetime. They would add to the opening words of a letter: "If you are well, it is well; I also am well." Persons like ourselves would do well to say. "If you are studying philosophy, it is well." For this is just what "being well" means. Without philosophy the mind is sickly.

The remedies for all our diseases will be discovered long after we are dead; and the world will be made a fit place to live in, after the death of most of those by whose exertions it will have been made so. It is to be hoped that those who live in those days will look back with sympathy to their known and unknown benefactors.

So our self-feeling in this world depends entirely on what we back ourselves to be and do.

In a word, neither death, nor exile, nor pain, nor anything of this kind is the real cause of our doing or not doing any action, but our inward opinions and principles.

The most important part of education - to teach the meaning of to know (in the scientific sense). The last statement in her notebook

Nothing can be done at once hastily and prudently.

So that it will be found that the fundamental fault in the character of women is that they have no "sense of justice ." This arises from their deficiency in the power of reasoning already referred to, and reflection, but is also partly due to the fact that Nature has not destined them, as the weaker sex, to be dependent on strength but on cunning; this is why they are instinctively crafty, and have an ineradicable tendency to lie.

Fear and destructiveness are the major emotional sources of fascism, eros belongs mainly to democracy.

Any plea ... for institutionalized risk-assessment, beefed-up bioethics panels, academic review bodies, worse-case scenario planning, more intensive computer simulations, systematic long-term planning and the institutionalized study of existential risks is admirable. But so is urgent action to combat the global pandemic of suffering. "The easiest pain to bear is someone else's"
