Men go to a fire for entertainment. When I see how eagerly men will run to a fire, whether in warm or in cold weather, by day or by night, dragging an engine at their heels, I'm astonished to perceive how good a purpose the level of excitement is made to serve.

History proves nothing because it contains everything.

Rationalism is an adventure in the clarification of thought.

Injustice, poverty, slavery, ignorance - these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible.

The peculiar and amusing nature of those answers stems from the fact that modern history is like a deaf person who is in the habit of answering questions that no one has put to them. If the purpose of history be to give a description of the movement of humanity and of the peoples, the first question - in the absence of a reply to which all the rest will be incomprehensible - is: what is the power that moves peoples? To this, modern history laboriously replies either that Napoleon was a great genius, or that Louis XIV was very proud, or that certain writers wrote certain books. All that may be so and mankind is ready to agree with it, but it is not what was asked.

It was under Catholic Feudalism that they were first united; a union for which their incorporation into the Roman empire had prepared them, and which was finally organized by the incomparable genius of Charlemagne.

To require that all of these must be reducible to a single version is to make the mistake of supposing that 'Which are the real objects?' is a question that makes sense independently of our choice of concepts.

The worst is not ennui nor despair but their encounter, their collision. To be crushed between the two!

Blood doubly unites us, for we share the same blood and we have spilled blood.

We have busied ourselves and contented ourselves long enough with speaking and writing; now at last we demand that the word become flesh, the spirit matter; we are as sick of political as we are of philosophical idealism; we are determined to become political materialists.

In countries where associations are free, secret societies are unknown. In America there are factions, but no conspiracies.

O Fortune, cruellest of heavenly powers, why make such game of this poor life of ours?

When I see someone in anxiety, I say to myself, What can it be that this fellow wants? For if he did not want something that was outside of his control, how could he still remain in anxiety?

When he was asked what advantage had accrued to him from philosophy, his answer was, "The ability to hold converse with myself."

Science has adapted itself entirely to the wealthy classes and accordingly has set itself to heal those who can afford everything, and it prescribes the same methods for those who have nothing to spare.

But, braggart demons, we postpone our end: how could we renounce the display of our freedom, the show of our pride?

History is mere Empiricism; it has only facts to communicate, and all its proofs are founded upon facts alone. To attempt to rise to Primeval History on this foundation of fact, or to argue by this means how such or such a thing might have been, and then to take for granted that it has been so in reality,is to stray beyond the limits of History, and produce an a priori History; just as the Philosophy of Nature, referred to in our preceding lecture, endeavoured to find an a priori Science of Physics.

Falsehood and delusion are allowed in no case whatever: But, as in the exercise of all the virtues, there is an œconomy of truth. It is a sort of temperance, by which a man speaks truth with measure that he may speak it the longer.

Politics is, as it were, the gizzard of society, full of grit and gravel, and the two political parties are its two opposite halves, - sometimes split into quarters, it may be, which grind on each other. Not only individuals, but States, have thus a confirmed dyspepsia, which expresses itself, you can imagine by what sort of eloquence. Thus our life is not altogether a forgetting, but also, alas! to a great extent, a remembering of that which we should never have been conscious of, certainly not in our waking hours. Why should we not meet, not always as dyspeptics, to tell our bad dreams, but sometimes as eupeptics, to congratulate each other on the ever glorious morning? I do not make an exorbitant demand, surely.

In the tragedies of the early seventeenth century, madness too provided the dénouement, but it did so in liberating the truth. It still opened onto language, to a renewed form of speech, that of explanation and of the real regained. The most it could ever be was the penultimate moment of tragedy. Not the closing moment, as in Andromaque, where no truth appears, other than, in Delirium, the truth of a passion that finds its fullest, most perfect expression in madness.

The quality of feeling is the true psychical representative of the first category of the immediate as it is in its immediacy, of the present in its direct positive presentness. Qualities of feeling show myriad-fold variety, far beyond what the psychologists admit. This variety however is in them only insofar as they are compared and gathered into collections. But as they are in their presentness, each is sole and unique; and all the others are absolute nothingness to it - or rather much less than nothingness, for not even a recognition as absent things or as fictions is accorded to them. The first category, then, is Quality of Feeling, or whatever is such as it is positively and regardless of aught else.

I will destroy this house, and no one will be able to build it....

Don't for heaven's sake, be afraid of talking nonsense! But you must pay attention to your nonsense.

Poets and priests were one in the beginning, and they only separated in later times. But the real poet is always a priest, just as the real priest always remains a poet.

Self-knowledge - the bitterest knowledge of all and also the kind we cultivate least: what is the use of catching ourselves out, morning to night, in the act of illusion, pitilessly tracing each act back to its root, and losing case after case before our own tribunal?

The last thing abandoned by a party is its phraseology, because among political parties, as elsewhere, the vulgar make the language, and the vulgar abandon more easily the ideas that have been instilled into it than the words that it has learnt. France Before The Consulate, Chapter I: "How the Republic was ready to accept a master", in Memoir, Letters, and Remains, Vol I (1862), p. 266 Variant translation: The last thing a political party gives up is its vocabulary. This is because, in party politics as in other matters, it is the crowd who dictates the language, and the crowd relinquishes the ideas it has been given more readily than the words it has learned.

These Lectures, conjoined with those which have already appeared under the titles of "The Characteristics of the Present Age," and "The Nature of the Scholar," in the latter of which the tone of thought that governs the present course is applied to a particular subject, form a complete scheme of popular instruction, of which the present work exhibits the highest and clearest summit; and, taken together, they are the result of a process of self-culture, unceasingly pursued during the last six or seven years of my life, with greater leisure and in riper maturity, by means of that Philosophy in which I have been a partaker for thirteen years, and which, although, I hope, it has changed many things in me, has nevertheless itself suffered no change whatever during that period.

There are but few points in which the English, as a people, are entitled to the moral pre-eminence with which they are accustomed to compliment themselves at the expense of other nations: but, of these points, perhaps the one of greatest importance is, that the higher classes do not lie, and the lower, though mostly habitual liars, are ashamed of lying. To run any risk of weakening this feeling, a difficult one to create, or, when once gone, to restore, would be a permanent evil too great to be incurred for so very temporary a benefit as the ballot would confer, even on the most exaggerated estimate necessity.

The real issue is not whether two and two make four or whether two and two make five, but whether life advances by men who love words or men who love living.

So far as living instruments of labour are concerned, for instance horses, their reproduction is timed by nature itself. Their average lifetime as instruments of labour is determined by the laws of nature. As soon as this term has expired they must be replaced by new ones. A horse cannot be replaced piecemeal; it must be replaced by another horse.

In the final, positive state, the mind has given over the vain search after Abolute notions, the origin and destination of the universe, and the cause of phenomenon, and applies itself to the tudy of their laws, - that is, their invariable relations of succession and resemblance. Reasoning and observation, duly combined, are the means of this knowledge. What is now understood when we speak of an explanation of the facts is simply the establishment of a connection between single phenomena and some general facts, the number of which continually diminishes with the progress of science.

Having destroyed all my connections, burned my bridges, I should feel a certain freedom, and in fact I do. One so intense I am afraid to rejoice in it.

Everything that is possible demands to exist.

New truth is often uncomfortable, especially to the holders of power; nevertheless, amid the long record of cruelty and bigotry, it is the most important achievement of our intelligent but wayward species.

Humans are amphibians - half spirit and half animal.... As spirits they belong to the eternal world, but as animals they inhabit time.

How many valiant men we have seen to survive their own reputation!

Karsky: I met your father last week. Are you still interested in hearing how he is doing?

Hugo: No. 

Karsky: It is very probable that you will be responsible for his death.

Hugo: It is virtually certain that he is responsible for my life. We are even.

There is nothing more notable in Socrates than that he found time, when he was an old man, to learn music and dancing, and thought it time well spent.

The ideal form for a poem, essay, or fiction, is that which the ideal writer would evolve spontaneously. One in whom the powers of expression fully responded to the state of feeling, would unconsciously use that variety in the mode of presenting his thoughts, which Art demands.

Respectable scientists like de Broglie himself accept wave mechanics because it confers coherence and unity upon the experimental findings of contemporary science, and in spite of the astonishing changes it implies in connection with ideas of causality, time, and space, but it is because of these changes that it wins favor with the public. The great popular success of Einstein was the same thing. The public drinks in and swallows eagerly everything that tends to dispossess the intelligence in favor of some technique; it can hardly wait to abdicate from intelligence and reason and from everything that makes man responsible for his destiny.

In each separate thing that you do consider the matters which come first, and those which follow after, and only then approach the thing itself.

I am not sure but I should betake myself in extremities to the liberal divinities of Greece, rather than to my country's God. Jehovah, though with us he has acquired new attributes, is more absolute and unapproachable, but hardly more divine, than Jove. He is not so much of a gentleman, not so gracious and catholic, he does not exert so intimate and genial an influence on nature, as many a god of the Greeks.

It is sometimes maintained that racial mixture is biologically undesirable. There is no evidence whatever for this view. Nor is there, apparently, any reason to think that Negroes are congenitally less intelligent than white people, but as to that it will be difficult to judge until they have equal scope and equally good social conditions.

The slaves of developed industrial civilization are sublimated slaves.

If an angel were ever to tell us anything of his philosophy I believe many propositions would sound like 2 times 2 equals 13.

Men can be provincial in time, as well as in place.

I maintain that in every special natural doctrine only so much science proper is to be met with as mathematics; for... science proper, especially of nature, requires a pure portion, lying at the foundation of the empirical, and based upon à priori knowledge of natural things. ...the conception should be constructed. But the cognition of the reason through construction of conceptions is mathematical. A pure philosophy of nature in general, namely, one that only investigates what constitutes a nature in general, may thus be possible without mathematics; but a pure doctrine of nature respecting determinate natural things (corporeal doctrine and mental doctrine), is only possible by means of mathematics; and as in every natural doctrine only so much science proper is to be met with therein as there is cognition à priori, a doctrine of nature can only contain so much science proper as there is in it of applied mathematics.

Montaigne puts not self-satisfied understanding but a consciousness astonished at itself at the core of human existence.

A man cannot become a child again, or he becomes childish.
