By convention sweet is sweet, bitter is bitter, hot is hot, cold is cold, color is color; but in truth there are only atoms and the void.

Men that look no further than their outsides, think health an appurtenance unto life, and quarrel with their constitutions for being sick; but I that have examined the parts of man, and know upon what tender filaments that fabric hangs, do wonder that we are not always so; and considering the thousand doors that lead to death, do thank my God that we can die but once.

In fact the opposition of instinct and reason is mainly illusory. Instinct, intuition, or insight is what first leads to the beliefs which subsequent reason confirms or confutes; but the confirmation, where it is possible, consists, in the last analysis, of agreement with other beliefs no less instinctive. Reason is a harmonising, controlling force rather than a creative one. Even in the most purely logical realms, it is insight that first arrives at what is new.

If you are not already dead, forgive. Rancor is heavy, it is worldly; leave it on earth: die light.

If the ethical, that is, social morality is the highest ... then no categories are needed other than the Greek philosophical categories.

Reason as an organ for perceiving the true nature of reality and determining the guiding principles of our lives has come to be regarded as obsolete.

Everything that makes diversity of kinds, of species, differences, properties... everything that consists in generation, decay, alteration and change is not an entity, but a condition and circumstance of entity and being, which is one, infinite, immobile, subject, matter, life, death, truth, lies, good and evil.

All poetry is supposed to be instructive but in an unnoticeable manner; it is supposed to make us aware of what it would be valuable to instruct ourselves in; we must deduce the lesson on our own, just as with life.

The destiny of the spiritual World, and, - since this is the substantial World, while the physical remains subordinate to it, or, in the language of speculation, has no truth as against the spiritual, - the final cause of the World at large, we allege to be the consciousness of its own freedom on the part of Spirit, and ipso facto, the reality of that freedom.

Virtue runs no risk of becoming contemptible by being exposed to view, and it is better to be despised for simplicity than to be tormented by continual hypocrisy.

It is an odd fact that anyone who wishes to start a war must always make it appear that he is fighting in a just cause even if the real motive is naked aggression. Fortunately for the would-be aggressor, a "just cause" is very easy to find.

People try to do all sorts of clever and difficult things to improve life instead of doing the simplest, easiest thing-refusing to participate in activities that make life bad.

The wise man who has charge of governing the empire should know the cause of disorder before he can put it in order. Unless he knows its cause, he cannot regulate it.

All human activity is prompted by desire. There is a wholly fallacious theory advanced by some earnest moralists to the effect that it is possible to resist desire in the interests of duty and moral principle. I say this is fallacious, not because no man ever acts from a sense of duty, but because duty has no hold on him unless he desires to be dutiful. If you wish to know what men will do, you must know not only, or principally, their material circumstances, but rather the whole system of their desires with their relative strengths.

I subdue matter and force it to become my mind's good medium. I rejoice in plants, in animals, in man and in gods, as though they were my children. I feel all the universe nestling about me and following me as though it were my own body.

By virtue of its innermost intention, and like all questions about language, structuralism escapes the classical history of ideas which already supposes structuralism's possibility, for the latter naively belongs to the province of language and propounds itself within it.Nevertheless, by virtue of an irreducible region of irreflection and spontaneity within it, by virtue of the essential shadow of the undeclared, the structuralist phenomenon will deserve examination by the historian of ideas. For better or for worse. Everything within this phenomenon that does not in itself transparently belong to the question of the sign will merit this scrutiny; as will everything within it that is methodologically effective, thereby possessing the kind of infallibil-ity now ascribed to sleepwalkers and formerly attributed to instinct, which was said to be as certain as it was blind.

Someone in despair despairs over something. So, for a moment, it seems, but only for a moment. That same instant the true despair shows itself, or despair in its true guise. In despairing over something he was really despairing over himself, and he wants now to be rid of himself.

I entirely agree with you, as to the ill tendency of the affected doubts of some philosophers, and fantastical conceit of others. I am even so far gone of late in this way of think, that I have quitted several of the sublime notions I had got in their schools for vulgar opinions. And I give it you on my word, since this revolt from metaphysical notions to the plain dictates of nature and common sense, I find my understanding strangely enlightened, so that I can now easily comprehend a great many thing which before were all mystery and riddle.

In relation to any act of life, the mind acts as a killjoy.

Possibility is not a luxury; it is as crucial as bread. Undoing Gender.

Inasmuch as it is my wish only to compose a hymn of thanksgiving in honour of the god, I have deemed it quite sufficient to discourse to the best of my ability concerning his nature. I do not think I have wasted words to no purpose: the maxim, "Sacrifice to the immortal gods according to thy means," I accept as applying not merely to burnt-offerings, but also to our praises addressed unto the gods. I pray for the third time, in return for this my good intention, the Sun lord of the universe to be propitious to me, and to bestow on me a virtuous life, a more perfect understanding, and a superhuman intellect, and a very easy release from the trammels of life at the time appointed: and after that release, an ascension up to himself, and an abiding place with him, if possible, for all time to come; or if that be too great a recompense for my past life, many and long-continued revolutions around his presence!

What is called "objectivity," scientific for instance (in which I firmly believe, in a given situation) imposes itself only within a context which is extremely vast, old, firmly established, or rooted in a network of conventions ... and yet which still remains a context.

Never would the humanities or psychoanalysis have existed if it had been miraculously possible to reduce man to his "rational" behaviors.

He who is not sure of his memory, should not undertake the trade of lying. 

Nearly allied to justice are the virtues of beneficence, compassion, gratitude, piety, and friendship.

I call a sign which stands for something merely because it resembles it, an icon. Icons are so completely substituted for their objects as hardly to be distinguished from them. Such are the diagrams of geometry. A diagram, indeed, so far as it has a general signification, is not a pure icon; but in the middle part of our reasonings we forget that abstractness in great measure, and the diagram is for us the very thing. So in contemplating a painting, there is a moment when we lose the consciousness that it is not the thing, the distinction of the real and the copy disappears, and it is for the moment a pure dream, - not any particular existence, and yet not general. At that moment we are contemplating an icon.

If you do the job in a principled way, with diligence, energy and patience, if you keep yourself free of distractions, and keep the spirit inside you undamaged, as if you might have to give it back at any moment- If you can embrace this without fear or expectation-can find fulfillment in what you're doing now, as Nature intended, and in superhuman truthfulness (every word, every utterance)-then your life will be happy.

...nothing is stronger than true reality.

Echoing the Christian faith in free will, humanists hold that human beings are - or may someday become - free to choose their lives. They forget that the self that does the choosing has not itself been chosen.

First, the physicists in the persons of Faraday and Maxwell, proposed the "electromagnetic field" in contradistinction to matter, as a reality of a different category. Then, during the last century, the mathematicians, ... secretly undermined belief in the evidence of Euclidean Geometry. And now, in our time, there has been unloosed a cataclysm which has swept away space, time, and matter hitherto regarded as the firmest pillars of natural science, but only to make place for a view of things of wider scope and entailing a deeper vision. This revolution was promoted essentially by the thought of one man, Albert Einstein.

We are near awakening when we dream that we dream.

The God idea is growing more impersonal and nebulous in proportion as the human mind is learning to understand natural phenomena and in the degree that science progressively correlates human and social events.

The empiricist thinks he believes only what he sees, but he is much better at believing than at seeing.

If the press was to be free, nothing would be so important as precisely its liberation from every coercion that could be put on it in the name of a law. And, that it might come to that, I my own self should have to have absolved myself from obedience to the law.

The spirit of a production-centered, commodity-greedy society is such that only the non-conformist can defend himself sufficiently against it. Those who are seriously concerned with love as the only rational answer to the problem of human existence must, then, arrive at the conclusion that important and radical changes in our social structure are necessary, if love is to become a social and not a highly individualistic, marginal phenomenon.

To require that a so-called layman should not use his own reason in religious matters, particularly since religion is to be appreciated as moral, but instead follow the appointed clergyman and thus someone else's reason, is an unjust demand because as to morals every man must account for all his doings. The clergyman will not and even cannot assume such a responsibility.

My poor opinion is, that the closest connexion between Great Britain and Ireland, is essential to the well being, I had almost said, to the very being, of the two Kingdoms. ... I think indeed that Great Britain would be ruined by the separation of Ireland; but, as there are degrees even in ruin, it would fall the most heavily on Ireland. By such a separation Ireland would be the most completely undone Country in the world; the most wretched, the most distracted and, in the end, the most desolate part of the habitable Globe.

Mathematics, rightly viewed, possesses not only truth, but supreme beauty - a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of highest excellence, is to be found in mathematics as surely as in poetry. What is best in mathematics deserves not merely to be learnt as a task, but to be assimilated as a part of daily thought, and brought again and again before the mind with ever-renewed encouragement.

Religion may be purified. This great work was begun two hundred years ago: but men can only bear light to come in upon them by degrees.

This letter, if judged by the novelty and profundity of ideas it contains, is perhaps the most substantial piece of writing in the whole literature of mankind.

Every noble crown is, and on earth will forever be, a crown of thorns.

A company of solemn tyrants is impervious to all seductions.

Our subjective judgment of what seems like a good bet is irrelevant to what is actually a good bet.
