All styles are good except the boring kind.

Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory. The ideas must later take the mathematical form of a quantitative theory, to make possible the comparison with experiment.

Antisthenes ... was asked on one occasion what learning was the most necessary, and he replied, "To unlearn one's bad habits."

Who would govern that can get along without governing? He that is fittest for it, is of all men the unwillingest unless constrained.

Anxiety may be compared with dizziness. He whose eye happens to look down into the yawning abyss becomes dizzy. But what is the reason for this? It is just as much in his own eye as in the abyss, for suppose he had not looked down. Hence, anxiety is the dizziness of freedom, which emerges when the spirit wants to posit the synthesis and freedom looks down into its own possibility, laying hold of finiteness to support itself. Freedom succumbs to dizziness. Further than this, psychology cannot and will not go. In that very moment everything is changed, and freedom, when it again rises, sees that it is guilty. Between these two moments lies the leap, which no science has explained and which no science can explain. He who becomes guilty in anxiety becomes as ambiguously guilty as it is possible to become.

I have learned to seek my happiness by limiting my desires, rather than in attempting to satisfy them.

A blow from your friend is better than a kiss from your enemy.

Consciousness must essentially cover an interval of time; for if it did not, we could gain no knowledge of time, and not merely no veracious cognition of it, but no conception whatever. We are therefore, forced to say that we are immediately conscious through an infinitesimal interval of time.

It is all too easy to forget that there are emotional motivations in history, as well as economic ones.

Our liberty depends on the freedom of the press, and that cannot be limited without being lost.

I consider as lovers of books not those who keep their books hidden in their store-chests and never handle them, but those who, by nightly as well as daily use thumb them, batter them, wear them out, who fill out all the margins with annotations of many kinds, and who prefer the marks of a fault they have erased to a neat copy full of faults.

"Freedom" awakens your rage against everything that is not you; "egoism" calls you to joy over yourselves, to self-enjoyment.

History is full of religious wars; but, we must take care to observe, it was not the multiplicity of religions that produced these wars, it was the intolerating spirit which animated that one which thought she had the power of governing.

Limiting the liberty of each by the like liberty of all, excludes a wide range of improper actions, but does not exclude certain other improper ones.

Man differs from other animals in one very important respect, and that is that he has some desires which are, so to speak, infinite, which can never be fully gratified, and which would keep him restless even in Paradise. The boa constrictor, when he has had an adequate meal, goes to sleep, and does not wake until he needs another meal. Human beings, for the most part, are not like this.

My education, which was wholly his work, had been conducted without any regard to the possibility of its ending in this result; and I saw no use in giving him the pain of thinking that his plans had failed, when the failure was probably irremediable, and, at all events, beyond the power of his remedies. Of other friends, I had at that time none to whom I had any hope of making my condition intelligible. It was however abundantly intelligible to myself; and the more I dwelt upon it, the more hopeless it appeared.

Because that which is finite is always bounded with reference to something... it is necessary that there should be no end... Number also appears to be infinite, and mathematical magnitudes, and that which is beyond the heavens. And since that which is beyond is infinite, body also appears to be infinite, and it would seem that there are infinite worlds; for why is there rather void here than there? ...If also there is a vacuum, and an infinite place, it is necessary that there should be an infinite body: for in things which have a perpetual subsistence, capacity differs nothing from being. The speculation of the infinite is, however, attended with doubt: for many impossibilities happen both to those who do not admit that it has a subsistence, and to those who do. ...It is ...especially the province of a natural philosopher to consider if there be a sensible infinite magnitude.

In a word, human life is more governed by fortune than by reason; is to be regarded more as a dull pastime than as a serious occupation; and is more influenced by particular humour, than by general principles. Shall we engage ourselves in it with passion and anxiety? It is not worthy of so much concern. Shall we be indifferent about what happens? We lose all the pleasure of the game by our phlegm and carelessness. While we are reasoning concerning life, life is gone; and death, though perhaps they receive him differently, yet treats alike the fool and the philosopher.

The chief error in philosophy is overstatement.

Eventually, I believe, current attempts to understand the mind by analogy with man-made computers that can perform superbly some of the same external tasks as conscious beings will be recognized as a gigantic waste of time.

An ardent Jehovah's Witness once tried to convince me that if there were a God of love, he would certainly provide mankind with a reliable and infallible textbook for the guidance of conduct. I replied that no considerate God would destroy the human mind by making it so rigid and unadaptable as to depend upon one book, the Bible, for all the answers. For the use of words, and thus of a book, is to point beyond themselves to a world of life and experience that is not mere words or even ideas. Just as money is not real, consumable wealth, books are not life. To idolize scriptures is like eating paper currency.

Remember that you ought to behave in life as you would at a banquet. As something is being passed around it comes to you; stretch out your hand, take a portion of it politely. It passes on; do not detain it. Or it has not come to you yet; do not project your desire to meet it, but wait until it comes in front of you. So act toward children, so toward a wife, so toward office, so toward wealth.

The secret of happiness is to face the fact that the world is horrible, horrible, horrible.

The scientific attitude of mind involves a sweeping away of all other desires in the interests of the desire to know-it involves suppression of hopes and fears, loves and hates, and the whole subjective emotional life, until we become subdued to the material, able to see it frankly, without preconceptions, without bias, without any wish except to see it as it is, and without any belief that what it is must be determined by some relation, positive or negative, to what we should like it to be, or to what we can easily imagine it to be.

When the soul has descended into generation (from its first divine condition) she partakes of evil, and is carried a great way into a state the opposite of her first purity and integrity, to be entirely merged in which, is nothing more than to fall into a dark mire. ...The soul dies as much as it is possible for the soul to die: and the death to her is, while baptized or immersed in the present body, to descend into matter, and be wholly subjected by it; and after departing thence to lie there til it shall arise and turn its face away from the abhorrent filth. This is what is meant by falling asleep in Hades, of those who have come there.

One grasps incomparably more things in boredom than by labor, effort being the mortal enemy of meditation.

When Confucius and the Indian Scriptures were made known, no claim to monopoly of ethical wisdom could be thought of... It is only within this century [the 1800 's] that England and America discovered that their nursery tales were old German and Scandinavian stories; and now it appears that they came from India, and are therefore the property of all the nations.

It goes without saying that the normal durability of fixed capital is calculated on the supposition that all the conditions under which it can perform its functions normally during that time are fulfilled, just as we assume, in placing a mans life at 30 years on the average,that he will wash himself.

No wild beasts are such enemies to mankind as are most of the Christians in their deadly hatred of one another.

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.

The development of the human mind has practically extinguished all feelings, except a few sporadic kinds, like sound, colors, smells, warmth, etc., which now appear to be disconnected and separate.

If you wish to be loved, love.

I am quite convinced; and, believe me, if I were again beginning my studies, I should follow the advice of Plato and start with mathematics, a science which proceeds very cautiously and admits nothing as established until it has been rigidly demonstrated.

We replace God as best we can; for every god is good, provided he perpetuates in eternity our desire for a crucial solitude. . . .

To become sober is: to come to oneself in self-knowledge and before God as nothing before him, yet infinitely, unconditionally engaged.

In a free nation, it matters not whether individuals reason well or ill; it is sufficient that they do reason. Truth arises from the collision and from hence springs liberty, which is a security from the effects of reasoning.

One power descends and wants to scatter, to come to a standstill, to die. The other power ascends and strives for freedom, for immortality. These two armies, the dark and the light, the armies of life and of death, collide eternally.

I am sitting with a philosopher in the garden; he says again and again "I know that that's a tree", pointing to a tree that is near us. Someone else arrives and hears this, and I tell them: "This fellow isn't insane. We are only doing philosophy."

The charlatan takes very different shapes according to circumstances; but at bottom he is a man who cares nothing about knowledge for its own sake, and only strives to gain the semblance of it that he may use it for his own personal ends, which are always selfish and material.

Technologies themselves, regardless of content, produce a hemispheric bias in the users.

Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step farther, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling.

The need for novelty is the characteristic of an alienated gorilla.

I know well that many of my readers do not think as I do. This also is most natural and confirms the theorem. For although my opinion turn out erroneous, there will always remain the fact that many of those dissentient readers have never given five minutes' thought to this complex matter. How are they going to think as I do? But by believing that they have a right to an opinion on the matter without previous effort to work one out for themselves, they prove patently that they belong to that absurd type of human being which I have called the "rebel mass." It is precisely what I mean by having one's soul obliterated, hermetically closed. Here it would be the special case of intellectual hermetism.

It is the nature of science that answers automatically pose new and more subtle questions.

Art is not, as the metaphysicians say, the manifestation of some mysterious Idea of beauty or God; it is not, as the aesthetical physiologists say, [play or] a game in which one releases surplus energy, ...not the production of pleasing objects, and is above all, not pleasure itself, but it is the means of union among mankind, joining them in the same feelings, and necessary for the life and progress toward the good of the individual and of humanity.

The difficulty in philosophy is to say no more than we know.

Heroism feels and never reasons and therefore is always right.

Do you desire another case? Take that of the younger Marcus Cato, with whom Fortune dealt in a more hostile and more persistent fashion. But he withstood her, on all occasions, and in his last moments, at the point of death, showed that a brave man can live in spite of Fortune, can die in spite of her. His whole life was passed either in civil warfare, or under a political regime which was soon to breed civil war.

The Bhagavad-Gita is perhaps the most systematic scriptural statement of the Perennial Philosophy. To a world at war, a world that, because it lacks the intellectual and spiritual prerequisites to peace, can only hope to patch up some kind of precarious armed truce, it stands pointing, clearly and unmistakably, to the only road of escape from the self-imposed necessity of self-destruction.
