All art is autobiographical; the pearl is the oyster's autobiography.

Let him sensibly perceive, that the kindness he shews to others, is no ill husbandry for himself; but that it brings a return in kindness both from those that receive it, and those who look on. Make this a contest among children, who shall out-do one another in this way: and by this means, by a constant practise, children having made it easy to themselves to part with what they have, good nature may be settled in them into a habit, and they may take pleasure, and pique themselves in being kind, liberal and civil, to others.

Count all wickedness foreign and alien.

Paradise on earth is where I am.

The perception of beauty is a moral test.

But of such writers the number is yet (and will I fear always be so) small, that I shall not need to make many exceptions, when I treat of the usefulness of writing books of essays, in comparison of that of writing systematically: or, at least... whilst I presume not to judge of other men's abilities, I hope it may be lawful for me to confess freely to you concerning myself, that I am very sensible of my being far from having such a stock of experiments and observations, as I judge requisite to write systematically; and I am apt to impute many of the deficiencies to be met with in the theories and reasonings of such great wits as Aristotle, Campanella, and some other celebrated philosophers, chiefly to this very thing, that they have too hastily, and either upon a few observations, or at least without a competent number of experiments, presumed to establish principles, and deliver axioms.

Political thought and political instinct prove themselves theoretically and practically in the ability to distinguish friend and enemy. The high points of politics are simultaneously the moments in which the enemy is, in concrete clarity, recognized as the enemy.

Having always lived in fear of being surprised by the worst, I have tried in every circumstance to get a head start, flinging myself into misfortune long before it occurred.

The greatest and noblest conceptions have no image wrought plainly for human vision, which he who wishes to satisfy the mind of the inquirer can apply to some one of his senses and by mere exhibition satisfy the mind. We must therefore endeavor by practice to acquire the power of giving and understanding a rational definition of each one of them; for immaterial things, which are the noblest and greatest, can be exhibited by reason only, and it is for their sake that all we are saying is said. But it is always easier to practice in small matters than in greater ones.

What is necessary at this stage in our evolution is not a 'return' to the psychic powers of our ancestors, but an expansion of our own potential powers, based upon the certain knowledge that such powers exist.

I have endeavoured to show that no absolute structural line of demarcation, wider than that between the animals which immediately succeed us in the scale, can be drawn between the animal world and ourselves; and I may add the expression of my belief that the attempt to draw a physical distinction is equally futile, and that even the highest faculties of feeling and of intellect begin to germinate in lower forms of life.

Station, power, wealth-how inadequate they have proved! How useless and insecure!

Nature loves to hide her secrets, and she does not suffer the hidden truth about the essential nature of the gods to be flung in naked words to the ears of the profane...

All who delight in the pleasures of the belly, exceeding all measure in eating and drinking and love, find that the pleasures are brief and last but a short while-only so long as they are eating and drinking-but the pains that come after are many and endure. The longing for the same things keeps ever returning, and whenever the objects of one's desire are realized forthwith the pleasure vanishes, and one has no further use for them. The pleasure is brief, and once more the need for the same things returns.

Mr. Galton ...in his English Men of Science, has given ...cases showing individual variations in the type of memory... Some have it verbal. Others... for facts and figures, others for form. Most say... [it] must first be rationally conceived and assimilated.

All a writer has to do to get a woman is to say he's a writer. It's an aphrodisiac.

You shall have joy, or you shall have power, said God; you shall not have both.

Ideas are invented only as correctives to the past. Through repeated rectifications of this kind one may hope to disengage an idea that is valid.

Though he made a joke when asked to do the right thing, he always did it. He was so much more in earnest than he appeared. He did not do himself justice.

A clever child brought up with a foolish one can itself become foolish. Man is so perfectable and corruptible he can become a fool through good sense.

One of the principal motifs of Nietzsche's work is that Kant had not carried out a true critique because he was not able to pose the problem of critique in terms of values.

To be in touch with senses and emotions beyond conquest is to enter the realm of the mysterious.

He who dares not offend cannot be honest.

Our psychological experiences are all equally facts. There is nothing to choose between them. No psychological experience is "truer," so far as we are concerned, than any other. For even if one should correspond more closely to things in themselves as perceived by some hypothetical non-human being, it would be impossible for us to discover which it was. Science is no "truer" than common sense, or lunacy, or art, or religion. It permits us to organize our experience profitably; but tells us nothing about the real nature of the world to which our experiences are supposed to refer. From the internal reality, by which I mean the totality of psychological experiences, it actually separates us. Art, for example, deals with many more aspects of this internal reality than does science, which confines itself deliberately and by convention to the study of one very limited class of experiences - the experiences of sense.

Not merely in the realm of commerce but in the world of ideas as well our age is organizing a regular clearance sale. Everything is to be had at such a bargain that it is questionable whether in the end there is anybody who will want to bid. Every speculative price-fixer who conscientiously directs attention to the significant march of modern philosophy, every Privatdocent, tutor, and student, every crofter and cottar goes further. Perhaps it would be untimely and ill-timed to ask them where they are going.

Man is by nature unable to want God to be God. Indeed, he himself wants to be God, and does not want God to be God.

The reward in heaven is the perpetual bait, a bait that has caught man in an iron net, a strait-jacket which does not let him expand or grow. All pioneers of truth have been, and still are, reviled; they have been, and still are, persecuted. But did they ask humanity to pay the price? Did they seek to bribe mankind to accept their ideas? They knew too well that he who accepts a truth because of the bribe, will soon barter it away to a higher bidder...Proud and self-reliant characters prefer hatred to such sickening artificial love. Not because of any reward does a free spirit take his stand for a great truth, nor has such a one ever been deterred because of fear of punishment.

A little patience, and we shall see the reign of witches pass over, their spells dissolve, and the people, recovering their true sight, restore their government to its true principles. It is true that in the meantime we are suffering deeply in spirit, and incurring the horrors of a war and long oppressions of enormous public debt. If the game runs sometimes against us at home we must have patience till luck turns, and then we shall have an opportunity of winning back the principles we have lost, for this is a game where principles are at stake.

The universe is composed of matter, and, as a system, is sustained by motion. Motion is not a property of matter, and without this motion the solar system could not exist. Were motion a property of matter, that undiscovered and undiscoverable thing, called perpetual motion, would establish itself. It is because motion is not a property of matter, that perpetual motion is an impossibility in the hand of every being, but that of the Creator of motion. When the pretenders to Atheism can produce perpetual motion, and not till then, they may expect to be credited.

Faith consists in believing what reason cannot.

The whole world is in some ways better than it's ever been in the past. And, indeed, I think for many people the meaning of their lives really depends on that belief. If you strip out that belief in progress, if you start thinking of the world in the way in which the ancient pre-Christian Europeans did, or the Buddhists and the Hindus or the Taoists of China do, many people think that's a kind of despair. I don't know how many times I've been told "If I thought that, John, I wouldn't get up in the morning" and "If I agreed with you, John, that history had no pattern of that kind, I wouldn't get up in the morning." I said, "Well, stay in bed a bit longer, you might find a better reason for getting up."

I think people who are unhappy are always proud of being so, and therefore do not like to be told that there is nothing grand about their unhappiness. A man who is melancholy because lack of exercise has upset his liver always believes that it is the loss of God, or the menace of Bolshevism, or some such dignified cause that makes him sad. When you tell people that happiness is a simple matter, they get annoyed with you.

What we call Man's power over Nature turns out to be a power exercised by some men over other men with Nature as its instrument.

A distant enemy is always preferable to one at the gate.

The fact that a belief has a good moral effect upon a man is no evidence whatsoever in favor of its truth.

I think that yesterday was a crisis in my life. I finished the first part of Renouvier's second Essais and see no reason why his definition of free will-"the sustaining of a thought because I choose to when I might have other thoughts"-need be the definition of an illusion. At any rate, I will assume for the present-until next year-that it is no illusion. My first act of free will shall be to believe in free will.

Ancient histories, as one of our wits has said, are but fables that have been agreed upon.

Our English careers to born genius are twofold. There is the silent or unlearned career of the Industrialisms, which are very many among us; and there is the articulate or learned career of the three professions, Medicine, Law (under which we may include Politics), and the Church. Your born genius, therefore, will first have to ask himself, Whether he can hold his tongue or cannot? True, all human talent, especially all deep talent, is a talent to do, and is intrinsically of silent nature; inaudible, like the Sphere Harmonies and Eternal Melodies, of which it is an incarnated fraction.

When I was 4 years old ... I dreamt that I'd been eaten by a wolf, and to my great surprise I was in the wolf's stomach and not in heaven.

In the temple of science are many mansions, and various indeed are they that dwell therein and the motives that have led them thither. Many take to science out of a joyful sense of superior intellectual power; science is their own special sport to which they look for vivid experience and the satisfaction of ambition; many others are to be found in the temple who have offered the products of their brains on this altar for purely utilitarian purposes. Were an angel of the Lord to come and drive all the people belonging to these two categories out of the temple, the assemblage would be seriously depleted, but there would still be some men, of both present and past times, left inside. Our Planck is one of them, and that is why we love him. I am quite aware that we have just now lightheartedly expelled in imagination many excellent men who are largely, perhaps chiefly, responsible for the buildings of the temple of science; and in many cases, our angel would find it a pretty ticklish job to decide. But of one thing I feel sure: if the types we have just expelled were the only types there were, the temple would never have come to be, any more than a forest can grow which consists of nothing but creepers. For these people any sphere of human activity will do if it comes to a point; whether they become engineers, officers, tradesmen, or scientists depends on circumstances.Now let us have another look at those who have found favor with the angel. Most of them are somewhat odd, uncommunicative, solitary fellows, really less like each other, in spite of these common characteristics, than the hosts of the rejected. What has brought them to the temple? That is a difficult question and no single answer will cover it.

Time with its continuity logically involves some other kind of continuity than its own. Time, as the universal form of change, cannot exist unless there is something to undergo change, and to undergo a change continuous in time, there must be a continuity of changeable qualities.

Only geometry can hand us the thread [which will lead us through] the labyrinth of the continuum's composition, the maximum and the minimum, the infinitesimal and the infinite; and no one will arrive at a truly solid metaphysic except he who has passed through this [labyrinth].

I think that the principal and most basic spiritual need of the Russian People is the need for suffering, incessant and unslakeable suffering, everywhere and in everything. I think the Russian People have been infused with this need to suffer from time immemorial. A current of martyrdom runs through their entire history, and it flows not only from external misfortunes and disasters but springs from the very heart of the People themselves. There is always an element of suffering even in the happiness of the Russian People, and without it their happiness is incomplete.

The sentiment that dominates all Rousseau's works is a certain plebeian anger that excites him against every kind of superiority. The energetic submission of the wise man bends nobly under the indispensable empire of social distinctions, and never does be appear greater than when he bows; but Rousseau has nothing at all of this loftiness. Weak and surly, he spent his life spouting insults to the great, as he would have offered the same to the people if he had been born a great lord.

Wealth is a great sin in the eyes of God. Poverty is a great sin in the eyes of man.

No man has received from nature the right to give orders to others. Freedom is a gift from heaven, and every individual of the same species has the right to enjoy it as soon as he is in enjoyment of his reason.
