To become properly acquainted with a truth, we must first have disbelieved it, and disputed against it.

Three conceptions are perpetually turning up at every point in every theory of logic, and in the most rounded systems they occur in connection with one another. They are conceptions so very broad and consequently indefinite that they are hard to seize and may be easily overlooked. I call them the conceptions of First, Second, Third. First is the conception of being or existing independent of anything else. Second is the conception of being relative to, the conception of reaction with, something else. Third is the conception of mediation, whereby a first and second are brought into relation.

Apart from autograph hunters, I get... many letters from Hindus, beseeching me to adopt some form of mysticism, from young Americans, asking me where I think the line should be drawn in petting, and from Poles, urging me to admit that while all other nationalism may be bad that of Poland is wholly noble. I get letters from engineers who cannot understand Einstein, and from parsons who think that I cannot understand Genesis, from husbands whose wives have deserted them - not (they say) that that would matter, but the wives have taken the furniture with them, and what in these circumstances should an enlightened male do? ...I get letters (concerning whose genuineness I am suspicious) trying to get me to advocate abortion, and I get letters from young mothers asking my opinion of bottle-feeding.

Nietzsche ... does not shy from conscious exaggeration and one-sided formulations of his thought, believing that in this way he can most clearly set in relief what in his vision and in his inquiry is different from the run-of-the-mill.

No nation which has sunk into this state of dependence can raise itself out of it by the means which have usually been adopted hitherto. Since resistance was useless to it when it was still in possession of all its powers, what can such resistance avail now that it has been deprived of the greater part of them?

It might otherwise appear paradoxical that money can be replaced by worthless paper; but that the slightest alloying of its metallic content depreciates it.

Do not hire a man who does your work for money, but him who does it for love of it.

All which a man loves, for which he leaves everything else but that, is his god, thus the glutton and drunkard has for his idol his own flesh, the fornicator has for his idol the harlot and the greedy has for his idol silver and gold, and so the same for every other sinner.

Avoid melancholy with all your might. It hurts the service of God more than sin. Satan takes less pleasure in sin than in a man's melancholy over having sinned again and so feeling that he is a slave to sin. Thus the Evil One has caught the poor soul in the net of despair.

Kant was also quite aware that "the urgent need" of reason is both different from and "more than mere quest and desire for knowledge." Hence, the distinguishing of the two faculties, reason and intellect, coincides with a distinction between two altogether different mental activities, thinking and knowing.

The two guides call out to a man early and late. And yet, no, for when remorse calls to a man it is always late. The call to find the way again by seeking out God in the confession of sins is always at the eleventh hour. Whether you are young or old, whether you have sinned much or little, whether you have offended much or neglected much, the guilt makes this call come at the eleventh hour. The inner agitation of the heart understands what remorse insists upon, that the eleventh hour has come. For in the sense of time, the old man's age is the eleventh hour; and the instant of death, the final moment in the eleventh hour. The indolent youth speaks of a long life that lies before him. The indolent old man hopes that his death is still a long way off. But repentance and remorse belong to the eternal in a man.

By asserting the objectivity of the physical world, naturalism identifies the existence and the conditions of existence of the physical world with existence and the conditions of existence in general. It forgets that the world of the physicist necessarily refers back, through its intrinsic meaning, through the subjective world which one tries to exclude from reality as being pure appearance, conditioned by the empirical nature of man, which is incapable of reaching directly to a world of things in themselves. But while the world of the physicist claims to go beyond naive experience, his world really exists only in relation to naive experience.

Let us cultivate our garden.

Choose always the way that seems the best, however rough it may be; custom will soon render it easy and agreeable.

The characteristic activity of science is not construction, but induction. The more often something has occurred in the past, the more certain that it will in all the future. Knowledge relates solely to what is and to its recurrence. New forms of being, especially those arising from the historical activity of man, lie beyond empiricist theory. Thoughts which are not simply carried over from the prevailing pattern of consciousness, but arise from the aims and resolves of the individual, in short, all historical tendencies that reach beyond what is present and recurrent, do not belong to the domain of science.

The essence of totalitarian government, and perhaps the nature of every bureaucracy, is to make functionaries and mere cogs in the administrative machinery out of men, and thus to dehumanise them.

Naturally, every age thinks that all ages before it were prejudiced, and today we think this more than ever and are just as wrong as all previous ages that thought so. How often have we not seen the truth condemned! It is sad but unfortunately true that man learns nothing from history.

All morning, I did nothing but repeat: "Man is an abyss, man is an abyss." - I could not, alas, find anything better.

As these people are not convicted of forfeiting freedom, they have still a natural, perfect right to it; and the Governments whenever they come should, in justice set them free, and punish those who hold them in slavery.

Just acquiring this amount of "education" will not, by itself, make you an educated person, even less will it give you what Oakeshott calls "judgment." But if the manner of instruction is adequate, the student should be able to acquire this much knowledge in a way that combines intellectual openness, critical scrutiny, and logical clarity. If so, learning will not stop when the student leaves the university.

Truthfulness under oath is, by now, a matter of our civic religion, our relation to our fellow citizens rather than our relation to a nonhuman power.

Nicias, do you think you can erase with good deeds the wrongs you committed against your mother? What good deed will ever reach her? Her soul is a scorching noon time, without a single breath of a breeze, nothing moves, nothing changes, nothing lives there; a great emaciated sun, an immobile sun eternally consumes her.

Immature love says: "I love you because I need you." Mature love says: "I need you because I love you."

As for my own business, even that kind of surveying which I could do with most satisfaction my employers do not want. They would prefer that I should do my work coarsely and not too well, ay, not well enough. When I observe that there are different ways of surveying, my employer commonly asks which will give him the most land, not which is most correct.

Notwithstanding their attacks on the basic conception of rationalism, on synthetic a priori judgments, that is, material propositions that cannot be contradicted by any experience, the empiricist posits the forms of being as constant.

Nature is a structure of evolving processes. The reality is the process.

This world wants to be childish in order to make us believe that the adults are elsewhere, in the "real" world, and to conceal the fact that true childishness is everywhere-that it is that of the adults themselves who come here to act the child in order to foster illusions as to their real childishness.

"I don't want to! Why should I?" "Because more people will be happier if you do than if you don't." "So what? I don't care about other people." "You should." "But why?" "Because more people will be happier if you do than if you don't."

In a book called Symbolism, Its Meaning and Effect, Whitehead points out that perception is usually a matter of symbols, just like language; I say I see a book when I actually see a red oblong. The Transactionists (who have been influenced by Whitehead rather than Husserl) take this one stage further, and point out that when I 'perceive' something, I am actually making a bet with myself that what I perceive is what I think it is. In order to act and live at all, I have to make these bets; I cannot afford to make absolutely certain that things are what I think they are. But this means that we should not take our perceptions at face value, any more than Nietzsche was willing to take philosophy at its face value; we must allow for prejudice and distortion.

There is no knowledge that is not power.

I was once being interviewed by Barbara Walters [...] In between two of the segments she asked me [...] "But what would you do if the doctor gave you only six months to live?" I said, "Type faster." This was widely quoted, but the "six months" was changed to "six minutes," which bothered me. It's "six months."

A nihilist is not one who believes in nothing, but one who does not believe in what exists.

I am sitting with a philosopher in the garden; he says again and again "I know that that's a tree", pointing to a tree that is near us. Someone else arrives and hears this, and I tell them: "This fellow isn't insane. We are only doing philosophy."

It is difficult to fit the work of Nikolai Berdyaev into any neat category. The label that was used most frequently to characterize him was that of an "existential Christian philosopher" but ... his voice is equally relevant to psychology and psychoanalysis and it also constitutes a uniquely original commentary on the very nature of the person in our postmodern world especially in relation to spirituality.

"To stamp becoming with the character of being-that is the supreme will to power." (WM 617) This suggests that becoming only is if it is grounded in being as being: "That everything recurs is the closest approximation of a world of becoming to one of being."

I was walking late one night along a tree-lined path; a chestnut fell at my feet. The noise it made as it burst, the resonance it provoked in me, and an upheaval out of all proportion to this insignificant event thrust me into miracle, into the rapture of the definitive, as if there were no more questions - only answers. I was drunk on a thousand unexpected discoveries, none of which I could make use of. This is how I nearly reached the Supreme. But instead I went on with my walk.

In the history of madness, two events signal this change with singular clarity: in 1657, the founding of the Hôpital Général, and the Great Confinement of the poor; and in 1794, the liberation of the mad in chains at Bicêtre. Between these two singular and symmetrical events, something happened, whose ambiguity has perplexed historians of medicine: blind repression in an absolutist regime, according to some, and, according to others, the progressive discovery, by science and philanthropy, of madness in its positive truth. In fact, beneath these reversible meanings, a structure was taking shape, which did not undo that ambiguity but was decisive for it. This structure explains the passage from the medieval and humanist experience of madness to the experience that is our own, which confines madness in mental illness.

I need Christ, not something that resembles Him.

Obey the voice at eve obeyed at prime.

Hegel's theological discussion repeatedly asks what the true relation is between the individual man and a state that no longer satisfies his capacities but exists rather as an 'estranged' institution from which the active political interest of the citizens has disappeared. Hegel defined this state with almost the same categories as those of eighteenth century liberalism: the state rests on the consent of the individuals, it circumscribes their rights and duties and protects its members from those internal and external dangers that might threaten the perpetuation of the whole.

Your own philosophy condemns you and supports us.

Remember Bostrom's definition of existential risk, which refers to the annihilation not of human beings, but of "Earth-originating intelligent life." The replacement of our species by some other form of conscious intelligent life is not in itself, impartially considered, catastrophic. Even if the intelligent machines kill all existing humans, that would be...a very small part of the loss of value that Parfit and Bostrom believe would be brought about by the extinction of Earth-originating intelligent life. The risk posed by the development of AI, therefore, is not so much whether it is friendly to us, but whether it is friendly to the idea of promoting wellbeing in general, for all sentient beings it encounters, itself included.

That a man be willing, when others are so too, as farre-forth, as for Peace, and defence of himself he shall think it necessary, to lay down this right to all things; and be contented with so much liberty against other men, as he would allow other men against himself.

In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind. If any false opinion, embraced from appearances, has been found to prevail; as soon as farther experience and sounder reasoning have given us juster notions of human affairs, we retract our first sentiment, and adjust anew the boundaries of moral good and evil.

The family uses people, not for what they are, nor for what they are intended to be, but for what it wants them for - its own uses. It thinks of them not as what God has made them, but as the something which it has arranged that they shall be.

That is why St. John of the Cross calls faith a night. With those who have received a Christian education, the lower parts of the soul become attached to these mysteries when they have no right at all to do so. That is why such people need a purification of which St. John of the Cross describes the stages. Atheism and incredulity constitute an equivalent of such a purification.

As it has long been and shall be, not ever, I think, will unfathomable time be emptied of either. This quote refers to Love and Strife, the fundamental opposing and ordering forces in Empedocles' model of the cosmos.

Meditation on any theme, if positive and honest, inevitably separates him who does the meditating from the opinion prevailing around him, from that which ... can be called "public" or "popular" opinion.

I have sometimes told myself that if only there were a notice on church doors forbidding entry to anyone with an income above a certain figure, and a low one, I would be converted at once.

Capital is dead labor, that vampire-like, only lives by sucking living labor, and lives the more, the more labor it sucks.
