In France at least, the history of science and thought gives pride of place sciences, sciences of the necessary, all close to philosophy: one can observe in their history the almost uninterrupted emergence of truth and pure reason. The other disciplines, however - those, for example, that concern living beings, languages, or economic facts - are considered too tinged with empirical thought, too exposed to the vagaries of chance or imagery to age old traditions and external events, for it to be supposed that their history could be anything other irregular. At most, they are expected to provide evidence of a state of mind, an intellectual fashion, a mixture of archaism and bold conjecture, of intuition and blindness. But what if empirical knowledge, at a given time and in a given culture, did possess a well defined regularity.

In the face of the idea that truth might afford the opposite of satisfaction and turn out to be completely shocking to humanity at any given historical moment, ... the fathers of pragmatism made the satisfaction of the subject the criterion of truth. For such a doctrine there is no possibility of rejecting or even criticizing any species of belief that is enjoyed by its adherents.

I cannot conceive, how a body, destitute of understanding and sense, truly so called, can moderate and determine its own motions; especially so as to make them conformable to laws that it has no knowledge of.

If belief consists in an emotional reaction of the entire man on an object, how can we believe at will? We cannot control our emotions.... But gradually our will can lead us to the same results by a very simple method: we need only in cold blood act as if the thing in question were real, and keep acting as if it were real, and it will infallibly end by growing into such a connection with our life that it will become real. It will become so knit with habit and emotion that our interests in it will be those which characterize belief.

Profound skepticism is favorable to conventions, because it doubts that the criticism of conventions is any truer than they are.

Man grows used to everything, the scoundrel.

I am Alpha and Omega, the beginning and the end, the first and the last.

Once we recognize that all historical knowledge is relational knowledge, and can only be formulated with reference to the position of the observer, we are faced, once more, with the task of discriminating between what is true and what is false in such knowledge.

In the ancient notion of love, on the other hand, there is an element of anxiety. The noble fears the descent to the less noble, is afraid of being infected and pulled down. The "sage" of antiquity does not have the same firmness, the same inner certainty of himself and his own value, as the genius and hero of Christian love.

A commodity appears, at first sight, a very trivial thing, and easily understood.Its analysis shows that it is, in reality, a very queer thing, abounding in metaphysical subtleties and theological niceties.

If thou canst see sharp, look and judge wisely, says the philosopher.

It is not enough for a wise man to study nature and truth; he should dare state truth for the benefit of the few who are willing and able to think.

If your parent is just, revere him; if not, bear with him.

In the same year in which I began Latin, I made my first commencement in the Greek poet with the Iliad. After I had made some progress in this, my father put Pope's translation into my hands. It was the first English verse I had cared to read, and it became one of the books in which for many years I most delighted: I think I must have read it from twenty to thirty times through. I should not have thought it worth while to mention a taste apparently so natural to boyhood, if I had not, as I think, observed that the keen enjoyment of this brilliant specimen of narrative and versification is not so universal with boys, as I should have expected both à priori and from my individual experience.

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!

Science, ever since the time of the Arabs, has had two functions: (1) to enable us to know things, and (2) to enable us to do things.

Felicity is a continual progress of the desire from one object to another, the attaining of the former being still but the way to the latter.The cause whereof is that the object of man's desire is not to enjoy once only, and for one instant of time, but to assure forever the way of his future desire. And therefore the voluntary actions and inclinations of all men tend not only to the procuring, but also to the assuring of a contented life, and differ only in the way, which ariseth partly from the diversity of passions in diverse men, and partly from the difference of the knowledge or opinion each one has of the causes which produce the effect desired.

The happiness and unhappiness of the rational, social animal depends not on what he feels but on what he does; just as his virtue and vice consist not in feeling but in doing.

Your own philosophy condemns you and supports us.

Man with the great M is only an ideal, the species only something thought of.

There is no act, however virtuous, for which ingenuity may not find some bad motive.

Every faculty in one man is the measure by which he judges of the like faculty in another. I judge of your sight by my sight, of your ear by my ear, of your reason by my reason, of your resentment by my resentment, of your love by my love. I neither have, nor can have, any other way of judging about them.

There is no means of proving it is preferable to be than not to be.

Let it not be in any man's power to say truly of thee that thou art not simple or that thou art not good; but let him be a liar whoever shall think anything of this kind about thee; and this is altogether in thy power.

An infirmity which affects the whole race, is no proper object for the scorn of an individual who belongs to that race, and who, before he could expose it, must himself have been its slave.

The Bible is literature, not dogma.

The manly part is to do with might and main what you can do.

What do you think of the aspect of the money market? ... This time, by the by, the thing has assumed European dimensions such as have never been seen before, and I don't suppose we'll be able to spend much longer here merely as spectators. The very fact that I've at last got round to setting up house again and sending for my books seems to me to prove that the 'mobilisation' of our persons is AT HAND.

In conclusion, then, no satisfactory interpretation of quantum mechanics exists today. The questions posed by the confrontation between the Copenhagen interpretation and the hidden variable theorists go to the very foundations of microphysics, but the answers given by hidden variable theorists and Copenhagenists are alike unsatisfactory. Human curiosity will not rest until those questions are answered, but whether they will be answered by conceptual innovations within the framework of the present theory or only within the framework of an as yet unforeseen theory is unknown. The first step toward answering them has been attempted here. It is the modest but essential step of becoming clear on the nature and magnitude of the difficulties.

Not far from the invention of fire... we must rank the invention of doubt.

A handful of soldiers is always better than a mouthful of arguments.

Impulse, subjectivity and profanation, the old adversaries of materialistic alienation, now succumb to it. ... The representatives of the opposition to the authoritarian schema become witnesses to the authority of commercial success. ... In the service of success they renounce that insubordinate character which was theirs.

I am not bothered by the fact that I am not understood. I am bothered when I do not know others.

What of a truth that is bounded by these mountains and is falsehood to the world that lives beyond?

Society can and does execute its own mandates: and if it issues wrong mandates instead of right, or any mandates at all in things with which it ought not to meddle, it practises a social tyranny more formidable than many kinds of political oppression, since, though not usually upheld by such extreme penalties, it leaves fewer means of escape, penetrating much more deeply into the details of life, and enslaving the soul itself. Protection, therefore, against the tyranny of the magistrate is not enough: there needs protection also against the tyranny of the prevailing opinion and feeling; against the tendency of society to impose, by other means than civil penalties, its own ideas and practices as rules of conduct on those who dissent from them; to fetter the development, and, if possible, prevent the formation, of any individuality not in harmony with its ways, and compel all characters to fashion themselves upon the model of its own.

The thought is the significant proposition.

Too little liberty brings stagnation, and too much brings chaos.

Much of the modern resistance to chastity comes from men's belief that they "own" their bodies - those vast and perilous estates, pulsating with the energy that made the worlds, in which they find themselves without their consent and from which they are ejected at the pleasure of Another!

Most of the texts... preserved from this period come from writers... either... affiliated with the aristocratic party, or... distrustful of democratic or radically democratic institutions.

In fact, contempt for happiness is usually contempt for other people's happiness, and is an elegant disguise for hatred of the human race.

To call out for the hand of the enemy is a rather extreme measure, yet a better one, I think, than to remain in continual fever over an accident that has no remedy. But since all the precautions that a man can take are full of uneasiness and uncertainty, it is better to prepare with fine assurance for the worst that can happen, and derive some consolation from the fact that we are not sure that it will happen.

Men who prefer any load of infamy, however great, to any pressure of taxation, however light.

Your questions refer to words; so I have to talk about words. You say: The point isn't the word, but its meaning, and you think of the meaning as a thing of the same kind as the word, though also different from the word. Here the word, there the meaning.

The Law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.
