When the intensity of emotional conviction subsides, a man who is in the habit of reasoning will search for logical grounds in favour of the belief which he finds in himself.

Before a science can develop principles, it must possess concepts. Before a law of gravitation could be formulated, it was necessary to have the notions of "acceleration" and "weight."

What is the wisdom of a book compared with the wisdom of an angel?

We are told that Christ was killed for us, that His death has washed out our sins, and that by dying He has disabled death itself. That is the formula. That is Christianity. That is what has to be believed. Any theories we build up as to how Christ's death did all this are, in my view, quite secondary: mere plans or diagrams to be left alone if they do not help us, and, if they do help us, not to be confused with the thing itself.

As we divided natural philosophy in general into the inquiry of causes, and productions of effects: so that part which concerneth the inquiry of causes we do subdivide according to the received and sound division of causes. The one part, which is physic, inquireth and handleth the material and efficient causes; and the other, which is metaphysic, handleth the formal and final causes.

This art is music. It stands quite apart from all the others. In it we do not recognize the copy, the repetition, of any Idea of the inner nature of the world. Yet it is such a great and exceedingly fine art, its effect on man's innermost nature is so powerful, and it is so completely and profoundly understood by him in his innermost being as an entirely universal language, whose distinctness surpasses even that of the world of perception itself, that in it we certainly have to look for more than that.

Perhaps we cannot prevent this world from being a world in which children are tortured. But we can reduce the number of tortured children. And if you don't help us, who else in the world can help us do this?

No one can flatter himself that he is immune to the spirit of his own epoch, or even that he possesses a full understanding of it. Irrespective of our conscious convictions, each one of us, without exception, being a particle of the general mass, is somewhere attached to, colored by, or even undermined by the spirit which goes through the mass. Freedom stretches only as far as the limits of our consciousness.

Whatever is known to us by consciousness, is known beyond possibility of question. What one sees or feels, whether bodily or mentally, one cannot but be sure that one sees or feels. No science is required for the purpose of establishing such truths; no rules of art can render our knowledge of them more certain than it is in itself. There is no logic for this portion of our knowledge.

When all capital, all production, all exchange have been brought together in the hands of the nation, private property will disappear of its own accord, money will become superfluous, and production will so expand and man so change that society will be able to slough off whatever of its old economic habits may remain.

After Plotinus, says Schassler, fifteen centuries passed without the slightest scientific interest for the world of beauty and art. ...In reality, nothing of the kind happened. The science of aesthetics ... neither did nor could vanish, because it never existed. ... the Greeks were so little developed that goodness and beauty seemed to coincide. On that obsolete Greek view of life the science of aesthetics was invented by men of the eighteenth century, and especially shaped and mounted in Baumgarten's theory. The Greeks (as anyone may read in Bénard's book on Aristotle and Walter's work on Plato) never had a science of aesthetics.

The wise man should restrain his senses like the crane and accomplish his purpose with due knowledge of his place, time and ability.

Self-respect will keep a man from being abject when he is in the power of enemies, and will enable him to feel that he may be in the right when the world is against him.

Whatever can be done another day can be done today.

Nietzsche's problem is how to be a philosopher once he has grasped the finitude of philosophy.

The world is nothing, the man is all; in yourself is the law of all nature, and you know not yet how a globule of sap ascends; in yourself slumbers the whole of Reason; it is for you to know all, it is for you to dare all.

But as far as our own world is concerned, its gradual leveling-down - or, we might say, its death - appears to be proved. And how will this process affect the fate of our spirit? Will it wane with the degradation of the energy of our world and return to unconsciousness, or will it grow according as the utilizable energy diminishes and by virtue of the very efforts that it makes to retard this degradation and to dominate Nature? - for this it is that constitutes the life of the spirit. May it be that consciousness and its extended support are two powers in contraposition, the one growing at the expense of the other?

No sound ought to be heard in the church but the healing voice of Christian charity.

Philosophers often behave like little children who scribble some marks on a piece of paper at random and then ask the grown-up "What's that?" - It happened like this: the grown-up had drawn pictures for the child several times and said "this is a man," "this is a house," etc. And then the child makes some marks too and asks: what's this then?

All parties seem to be agreed on one point, that the dialects commonly spoken among the natives of this part of India contain neither literary nor scientific information, and are moreover so poor and rude that, until they are enriched from some other quarter, it will not be easy to translate any valuable work into them.

We live, in fact, in a world starved for solitude, silence, and privacy: and therefore starved for meditation and true friendship.

How vain it is to sit down to write when you have not stood up to live.

We hold that the most wonderful and splendid proof of genius is a great poem produced in a civilized age.

It is only the ignorant who despise education.

Part of what makes moral philosophy an anachronistic field is that its practitioners continue to argue in this very traditional and aprioristic way even though they themselves do not claim that one can provide a systematic and indubitable 'foundation' for the subject. Most of them rely on what are supposed to be 'intuitions' without claiming that those intuitions deliver uncontroversial ethical premises, on the one hand, or that they have an ontological or epistemological explanation of the reliability of those intuitions, on the other.

The point, as Marx saw it, is that dreams never come true.

We forfeit three-fourths of ourselves in order to be like other people.

The constitution of madness as mental illness, at the end of the eighteenth century, bears witness to a rupture in a dialogue, gives the separation as already enacted, and expels from the memory all those imperfect words, of no fixed syntax, spoken falteringly, in which the exchange between madness and reason was carried out. The language of psychiatry, which is a monologue by reason about madness, could only have come into existence in such a silence.

From the fundamental nature of the Philistine, it follows that, in regard to others, as he has no intellectual but only physical needs, he will seek those who are capable of satisfying the latter not the former. And so of all the demands he makes of others the very smallest will be that of any outstanding intellectual abilities. On the contrary, when he comes across these they will excite his antipathy and even hatred. For here he has a hateful feeling of inferiority and also a dull secret envy which he most carefully attempts to conceal even from himself; but in this way it grows sometimes into a feeling of secret rage and rancour. Therefore it will never occur to him to assess his own esteem and respect in accordance with such qualities, but they will remain exclusively reserved for rank and wealth, power and influence, as being in his eyes the only real advantages to excel in which is also his desire.

Justice is what love looks like in public.

Because the peculiarity of man is that his machinery for reaction on external things has involved an imaginative transcript of these things, which is preserved and suspended in his fancy; and the interest and beauty of this inward landscape, rather than any fortunes that may await his body in the outer world, constitute his proper happiness. By their mind, its scope, quality, and temper, we estimate men, for by the mind only do we exist as men, and are more than so many storage-batteries for material energy. Let us therefore be frankly human. Let us be content to live in the mind.

Since we're all going to die, it's obvious that when and how don't matter.

To conclude: there are two well-known minor ways in which language has mattered to philosophy. On the one hand there is a belief that if only we produce good definitions, often marking out different senses of words that are confused in common speech, we will avoid the conceptual traps that ensnared our forefathers. On the other hand is a belief that if only we attend sufficiently closely to our mother tongue and make explicit the distinctions there implicit, we shall avoid the conceptual traps. One or the other of these curiously contrary beliefs may nowadays be most often thought of as an answer to the question Why does language matter to philosophy? Neither seems to me enough.

What a singular destiny has been that of this remarkable man! To be regarded in his own age as a classic, and in ours as a companion! To receive from his contemporaries that full homage which men of genius have in general received only from posterity! To be more intimately known to posterity than other men are known to their contemporaries!

It is clearly absurd to say that if you go on adding atoms together until they have fused into a complex molecule, that molecule will become capable of self-reproduction. It is like saying that a skyscraper is more capable of reproduction than a bungalow. And suppose life did come into being through some accidental interaction of molecules, sun and cosmic rays; why should it not be content to rest passively? Why should it have been possessed of a desire to persist and evolve?

Venerate the martyrs, praise, love, proclaim, honor them. But worship the God of the martyrs.

The union of the mathematician with the poet, fervor with measure, passion with correctness, this surely is the ideal.

The repose of sleep refreshes only the body. It rarely sets the soul at rest. The repose of the night does not belong to us. It is not the possession of our being. Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows.

When you wish to instruct, be brief; that men's minds may take in quickly what you say, learn its lesson, and retain it faithfully. Every word that is unnecessary only pours over the side of a brimming mind.

In every part of the universe we observe means adjusted with the nicest artifice to the ends which they are intended to produce; and in the mechanism of a plant, or animal body, admire how every thing is contrived for advancing the two great purposes of nature, the support of the individual, and the propagation of the species.

But if one should guide his life by true principles, man's greatest riches is to live on a little with contented mind; for a little is never lacking.

What a hell of an economic system! Some are replete with everything while others, whose stomachs are no less demanding, whose hunger is just as recurrent, have nothing to bite on. The worst of it is the constrained posture need puts you in. The needy man does not walk like the rest; he skips, slithers, twists, crawls.

The content or time-clothing of any medium or culture is the preceding medium or culture.

You women could make someone fall in love even with a lie.

One can imagine a computer simulation of the action of peptides in the hypothalamus that is accurate down to the last synapse. But equally one can imagine a computer simulation of the oxidation of hydrocarbons in a car engine or the action of digestive processes in a stomach when it is digesting pizza. And the simulation is no more the real thing in the case of the brain than it is in the case of the car or the stomach. Barring miracles, you could not run your car by doing a computer simulation of the oxidation of gasoline, and you could not digest pizza by running the program that simulates such digestion. It seems obvious that a simulation of cognition will similarly not produce the effects of the neurobiology of cognition.

What if the equality between us human being, in which we completely resemble one another, were that none of us really thinks about his being loved?

The man described for us, whom we are invited to free, is already in himself the effect of a subjection much more profound than himself. A 'soul' inhabits him and brings him to existence...the soul is the effect and instrument of political anatomy; the soul is the prison of the body.

But there has also been the rise of populist movements within existing liberal democracies, and particularly within the United States and Britain, which were... the leaders of the neoliberal revolution... in the 1980s...

The authority of science ... promotes and encourages the activity of observing, comparing, measuring and ordering the physical characteristics of human bodies.... Cartesian epistemology and classical ideals produced forms of rationality, scientificity and objectivity that, though efficacious in the quest for truth and knowledge, prohibited the intelligibility and legitimacy of black equality.... In fact, to "think" such an idea was to be deemed irrational, barbaric or mad.
