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.

There is no pleasure to me without communication: there is not so much as a sprightly thought comes into my mind that it does not grieve me to have produced alone, and that I have no one to tell it to.

Predicting the future is a hopeless, thankless task, with ridicule to begin with and, all too often, scorn to end with.

The good King of France desires only that you would take his word and let him be quiet till he has got the West Indies into his hands and his grandson well established in Spain, and then you may be sure you shall be as safe as he will let you be in your religion, property and trade, to all which who can be such an infidel as not to believe him a great friend?

Much early alchemy seems to have been adventure. You heated and mixed and burnt and pounded and to see what would happen. An adventure might suggest an hypothesis that can subsequently be tested, but adventure is prior to theory.

"Relation" in its idiomatic usage denotes something direct and active, something dynamic and energetic. It fixes attention upon the way things bear upon one another, their clashings and unitings, the way they fulfill and frustrate, promote and retard, excite and inhibit one another. Intellectual relations subsist in propositions; they state the connection of terms with one another. In art, as in nature and in life, relations are modes of interaction.

The universal nature has no external space; but the wondrous part of her art is that though she has circumscribed herself, everything which is within her which appears to decay and to grow old and to be useless she changes into herself, and again makes other new things from these very same, so that she requires neither substance from without nor wants a place into which she may cast that which decays. She is content then with her own space, and her own matter, and her own art.

That is what is meant, I think by the allegation that it is good simply to be alive, even if one is undergoing terrible experiences. The situation is roughly this: There are elements which, if added to one's experience, make life better; there are other elements which, if added to one's experience, make life worse. But what remains when these are set aside is not merely neutral: it is emphatically positive. Therefore life is worth living even when the bad elements of experience are plentiful, and the good ones too meager to outweigh the bad ones on their own. The additional positive weight is supplied by experience itself, rather than by any of its contents.

As far as I am concerned, I resign from humanity. I no longer want to be, nor can still be, a man. What should I do? Work for a social and political system, make a girl miserable? Hunt for weaknesses in philosophical systems, fight for moral and aesthetic ideals? It's all too little. I renounce my humanity even though I may find myself alone. But am I not already alone in this world from which I no longer expect anything?

These labourers, who must sell themselves piecemeal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.

There is no belief, however foolish, that will not gather its faithful adherents who will defend it to the death.

It may be that brain hardware has co-evolved with the internal virtual worlds that it creates. This can be called hardware-software co-evolution.

Man has an invincible inclination to allow himself to be deceived and is, as it were, enchanted with happiness when the rhapsodist tells him epic fables as if they were true, or when the actor in the theater acts more royally than any real king. So long as it is able to deceive without injuring, that master of deception, the intellect, is free; it is released from its former slavery and celebrates its Saturnalia. It is never more luxuriant, richer, prouder, more clever and more daring.

To his dog, every man is Napoleon; hence the constant popularity of dogs.

When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion.

I mean to lead a simple life, to choose a simple shell I can carry easily - like a hermit crab. But I do not. I find that my frame of life does not foster simplicity. My husband and five children must make their way in the world. The life I have chosen as a wife and mother entrains a whole caravan of complications.

Chance seldom interferes with the wise man; his greatest and highest interests have been, are, and will be, directed by reason throughout his whole life.

Americans combine to give fêtes, found seminaries, build churches, distribute books, and send missionaries to the antipodes. Hospitals, prisons, and schools take shape in that way. Finally, if they want to proclaim a truth or propagate some feeling by the encouragement of a great example, they form an association. In every case, at the head of any new undertaking, where in France you would find the government or in England some territorial magnate, in the United States you are sure to find an association. I have come across several types of association in America of which, I confess, I had not previously the slightest conception, and I have often admired the extreme skill they show in proposing a common object for the exertions of very many and in inducing them voluntarily to pursue it.

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?

I am a weak, ephemeral creature made of mud and dream. But I feel all the powers of the universe whirling within me.

Instead of funding issues of paper on the hypothecation of specific redeeming taxes (the only method of anticipating, in a time of war, the resources of times of peace, tested by the experience of nations), we are trusting to tricks of jugglers on the cards, to the illusions of banking schemes for the resources of the war, and for the cure of colic to inflations of more wind.

Ever since prehistoric antiquity one field of study after another has crossed the divide between what the historian might call its prehistory as a science and its history proper. These transitions to maturity have seldom been so sudden or so unequivocal as my necessarily schematic discussion may have implied. But neither have they been historically gradual, coextensive, that is to say, with the entire development of the fields within which they occurred.

Marriage is tough, because it is woven of all these various elements, the weak and the strong. "In love-ness" is fragile for it is woven only with the gossamer threads of beauty. It seems to me absurd to talk about "happy" and "unhappy" marriages.

An unbiased reader, on opening one of their [Fichte's, Schelling's or Hegel's] books and then asking himself whether this is the tone of a thinker wanting to instruct or that of a charlatan wanting to impress, cannot be five minutes in any doubt. ... The tone of calm investigation, which had characterized all previous philosophy, is exchanged for that of unshakeable certainty, such as is peculiar to charlatanry of every kind and at all times. ... From every page and every line, there speaks an endeavor to beguile and deceive the reader, first by producing an effect to dumbfound him, then by incomprehensible phrases and even sheer nonsense to stun and stupefy him, and again by audacity of assertion to puzzle him, in short, to throw dust in his eyes and mystify him as much as possible.

When, as a result of what was called Enlightenment in the eighteenth century, the priests had in fact almost entirely lost this function of guidance. Their place was taken by writers and scientists. In both cases it is equally absurd. Mathematics, physics, and biology are as remote from spiritual guidance as the art of arranging words. When that function is usurped by literature and science it proves there is no longer any spiritual life.

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 have known only one person in my life who claimed to have seen a ghost. It was a woman; and the interesting thing is that she disbelieved in the immortality of the soul before seeing the ghost and still disbelieves after having seen it. She thinks it was a hallucination. In other words, seeing is not believing. This is the first thing to get clear in talking about miracles.

The world is rejuvenated, but as Heine so wittily remarked, it was rejuvenated by romanticism to such a degree that it became a baby again.

There is certainly some chill and arid knowledge to be found upon the summits of formal and laborious science; but it is all round about you, and for the trouble of looking, that you will acquire the warm and palpitating facts of life.

I am happy because I want nothing from anyone. I do not care about money. Decorations, titles or distinctions mean nothing to me. I do not crave praise. The only thing that gives me pleasure, apart from my work, my violin, and my sailboat, is the appreciation of my fellow workers.

Even pacifist agitation or the nation-wide fever of big sports competitions acts as a spur to war fever in circumstances like ours. Any kind of excitement or emotion contributes to the possibility of dangerous explosions when the feelings of huge populations are kept inflamed even in peacetime for the sake of the advancement of commerce. Headlines mean street sales. It takes emotion to move merchandise. And wars and rumors of wars are the merchandise and also the emotion of the popular press.

In the life of the mass-order, the culture of the generality tends to conform to the demands of the average human being. Spirituality decays through being diffused among the masses when knowledge is impoverished in every possible way by rationalisation until it becomes accessible to the crude understanding of all.

So far from the posterior lobe, the posterior cornu, and the hippocampus minor, being structures peculiar to and characteristic of man, as they have been over and over again asserted to be, even after the publication of the clearest demonstration of the reverse, it is precisely these structures which are the most marked cerebral characters common to man with the apes. They are among the most distinctly Simian peculiarities which the human organism exhibits.

To found a great empire for the sole purpose of raising up a people of customers, may at first appear a project fit only for a nation of shopkeepers. It is however, a project altogether unfit for a nation of shopkeepers; but extremely fit for a nation whose government is influenced by shopkeepers.

We do not go to cowards for tender dealing; there is nothing so cruel as panic; the man who has least fear for his own carcase, has most time to consider others.

Mencius went to see King Huei of Liang. The king said, "Venerable sir, since you have not counted it far to come here, a distance of a thousand li, may I presume that you are provided with counsels to profit my kingdom?" Mencius replied, "Why must your Majesty use that word "profit"? What I am provided with, are counsels to benevolence and righteousness, and these are my only topics.

Conflicting intellectual positions may actually come to supplement one another. It is imperative in the present transitional period to make use of the intellectual twilight which dominates our epoch and in which all values and points of view appear in their genuine relativity. We must realize once and for all that the meanings which make up our world are simply an historically determined and continuously developing structure in which man develops, and are in no sense absolute.

No man can have a peaceful life who thinks too much about lengthening it.

A man is a god in ruins.

I could not be true and constant to the argument I handle, if I were not willing to go beyond others; but yet not more willing than to have others go beyond me again: which may the better appear by this, that I have propounded my opinions naked and unarmed, not seeking to preoccupate the liberty of men's judgments by confutations.

I like the dreams of the future better than the history of the past, - so good night!

I have in general no very exalted opinion of the virtue of paper government.

To be free in an age like ours, one must be in a position of authority. That in itself would be enough to make me ambitious.

That man, I declare, is happy whom nothing makes less strong than he is; he keeps to the heights, leaning upon none but himself; for one who sustains himself by any prop may fall.

When common words are appropriated as technical terms, their meaning may be modified, and must be rigorously fixed.
