The most difficult thing in life is to know yourself.

The science of pure mathematics, in its modern developments, may claim to be the most original creation of the human spirit.

Wealth is like sea-water; the more we drink, the thirstier we become.

There are and can be only two ways of searching into and discovering truth. The one flies from the senses and particulars to the most general axioms, and from these principles, the truth of which it takes for settled and immovable, proceeds to judgment and to the discovery of middle axioms. And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.

What would become of history, had we not a dependence on the veracity of the historian, according to the experience, what we have had of mankind?

Creating difficulties for himself for the pleasure of resolving them is a strange human mania.

Keep cool: it will be all one a hundred years hence.

Though thou loved her as thyself, As a self of purer clay, Tho' her parting dims the day, Stealing grace from all alive, Heartily know, When half-gods go, The gods arrive.

The greatest saving one can make in the order of thought is to accept the unintelligibility of the world and to pay attention to man.

O reader, to what shifts is poor Society reduced, struggling to give still some account of herself, in epochs when Cash Payment has become the sole nexus of man to men!

Although life is a matter of indifference, the use which you make of it is not a matter of indifference.

Communism is the doctrine of the conditions of the liberation of the proletariat.

We ought not to teach to little children, as a known fact, that which is not a known fact.

A prating barber asked Archelaus how he would be trimmed. He answered, "In silence."

Order thyself so, that thy Soul may always be in good estate; whatsoever become of thy body.

The death of dogma is the birth of morality.

There are only the wise of the highest class, and the stupid of the lowest class, who cannot be changed.

Bernie Sanders is...an anti-racist in his heart. Two, he's old-school. He's like me. He doesn't know the buzzwords. He doesn't endorse reparations, one moment in the last 30 years, silent on it. He has the consistency over the years decade after decade and therefore it's true in his language, in his rhetoric. There are times in which he doesn't... use the same kind of buzzwords. But when it comes to his fight against racism, going to jail in Chicago as a younger brother and he would go to jail again. He and I would go to jail together again in terms of fighting against police brutality. So in that sense, I would just tell my brothers and sisters, but especially my chocolate ones that they shouldn't be blinded by certain kinds of words they're looking for, that in the end, he is a long distance runner in the struggle against white supremacy.

Benevolence is the characteristic element of humanity.

When I was a student in the 1950s, I read Husserl, Sartre, Merleau-Ponty. When you feel an overwhelming influence, you try to open a window. Paradoxically enough, Heidegger is not very difficult for a Frenchman to understand. When every word is an enigma, you are in a not-too-bad position to understand Heidegger. Being and Time is difficult, but the more recent works are clearer. Nietzsche was a revelation to me. I felt that there was someone quite different from what I had been taught. I read him with a great passion and broke with my life, left my job in the asylum, left France: I had the feeling I had been trapped. Through Nietzsche, I had become a stranger to all that.

Of things said without any combination, each signifies either substance or quantity or qualification or a relative or where or when or being-in-a-position or having or doing or being affected. To give a rough idea, examples of substance are man, horse; of quantity: four-foot, five-foot; of qualification: white, grammatical; of a relative: double, half, larger; of where: in the Lyceum, in the market-place; of when: yesterday, last-year; of being-in-a-position: is-lying, is sitting; of having: has-shoes-on, has-armour-on; of doing: cutting, burning; of being-affected: being-cut, being-burned.

A man does not kill himself, as is commonly supposed, in a fit of madness but rather in a fit of unendurable lucidity, in a paroxysm which may, if so desired, be identified with madness; for an excessive perspicacity, carried to the limit and of which one longs to be rid at all costs, exceeds the context of reason.

Is not marriage an open question, when it is alleged, from the beginning of the world, that such as are in the institution wish to get out, and such as are out wish to get in?

It is difficult to free fools from the chains they revere.

When your father is alive, observe his will. When your father is dead observe his former actions. If, for three years after the death of your father you do not change from the ways of your father, you can be called a 'real son'.

The blues is relevant today because when we look down through the corridors of time, the black American interpretation of tragicomic hope in the face of dehumanizing hate and oppression will be seen as the only kind of hope that has any kind of maturity in a world of overwhelming barbarity and bestiality. That barbarity is found not just in the form of terrorism but in the form of the emptiness of our lives - in terms of the wasted human potential that we see around the world. In this sense, the blues is a great democratic contribution of black people to world history.

Anarchy, in its own nature, is an evil of short duration. The more horrible are the mischiefs it inflicts, the more does it hasten to a close.

The needs of a human being are sacred. Their satisfaction cannot be subordinated either to reasons of state, or to any consideration of money, nationality, race, or colour, or to the moral or other value attributed to the human being in question, or to any consideration whatsoever. There is no legitimate limit to the satisfaction of the needs of a human being except as imposed by necessity and by the needs of other human beings. The limit is only legitimate if the needs of all human beings receive an equal degree of attention.

If you could be alarmed into the semblance of modesty, you would charm everybody; but remember my joke against you about the Moon and the Solar System;-"Damn the solar system! bad light - planets too distant - pestered with comets - feeble contriviance; - could make a better with great ease."

No human being escapes the necessity of conceiving some good outside himself towards which his thought turns in a movement of desire, supplication, and hope. consequently, the only choice is between worshipping the true God or an idol. Every atheist is an idolater - unless he is worshipping the true God in his impersonal aspect. The majority of the pious are idolaters.

It is impossible for motion to subsist without place, and void, and time.

So live, my boys, as brave men; and if fortune is adverse, front its blows with brave hearts.

To say, therefore, that thought cannot happen in an instant, but requires a time, is but another way of saying that every thought must be interpreted in another, or that all thought is in signs.

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

Nothing is terrible except fear itself.

I'd rather be mad than feel pleasure.

Marriage as a community of interests unfailingly means the degradation of the interested parties, and it is the perfidy of the world's arrangements that no one, even if aware of it, can escape such degradation. The idea might therefore be entertained that marriage without ignominy is a possibility reserved for those spared the pursuit of interests, for the rich. But the possibility is purely formal, for the privileged are precisely those in whom the pursuit of interests has become second-nature-they would not otherwise uphold privilege.

"Earth loves the rain, the proud sky loves to give it." The whole world loves to create futurity. I say then to the world, "I share your love." Is this not the source of the phrase, "This loves to happen"?

Train any population rationally, and they will be rational. Furnish honest and useful employments to those so trained, and such employments they will greatly prefer to dishonest or injurious occupations. It is beyond all calculation the interest of every government to provide that training and that employment; and to provide both is easily practicable.

I believe that there is a necessary connection in both directions between the physical and the mental, but that it cannot be discovered a priori. Opinion is strongly divided on the credibility of some kind of functionalist reductionism, and I won't go through my reasons for being on the antireductionist side of that debate. Despite significant attempts by a number of philosophers to describe the functional manifestations of conscious mental states, I continue to believe that no purely functionalist characterization of a system entails - simply in virtue of our mental concepts - that the system is conscious.

We do not obtain the most precious gifts by going in search of them but by waiting for them. Man cannot discover them by his own powers, and if he sets out to seek for them he will find in their place counterfeits of which he will be unable to discern falsity.

Only at quite rare moments have I felt really glad to be alive. I could not but feel with a sympathy full of regret all the pain that I saw around me, not only that of men but that of the whole creation. From this community of suffering I have never tried to withdraw myself. It seemed to me a matter of course that we should all take our share of the burden of pain which lies upon the world.

It is easy for us to criticize the prejudices of our grandfathers, from which our fathers freed themselves. It is more difficult to search for prejudices among the beliefs and values that we hold.

People are said to believe in God, or to disbelieve in Adam and Eve. But in such cases what is believed or disbelieved is that there is an entity answering a certain description. This, which can be believed or disbelieved is quite different from the actual entity (if any) which does answer the description. Thus the matter of belief is, in all cases, different in kind from the matter of sensation or presentation, and error is in no way analogous to hallucination. A hallucination is a fact, not an error; what is erroneous is a judgment based upon it.

Fine manners need the support of fine manners in others, and this is a gift interred only by the self.

Of course I base my characters partly on the people I know-one can't escape it-but fictional characters are oversimplified; they're much less complex than the people one knows.
