To a wise man, the whole earth is open; for the native land of a good soul is the whole earth.

I have often regretted my speech, never my silence.

To such a one, already filled with intellectual substance, and possessing what we may call the practical gold-bullion of human culture, it was an obvious improvement that he should be taught to speak it out of him on occasion; that he should carry a spiritual banknote producible on demand for what of "gold-bullion" he had, not so negotiable otherwise, stored in the cellars of his mind. A man, with wisdom, insight and heroic worth already acquired for him, naturally demanded of the schoolmaster this one new faculty, the faculty of uttering in fit words what he had. A valuable superaddition of faculty:-and yet we are to remember it was scarcely a new faculty; it was but the tangible sign of what other faculties the man had in the silent state.

The first authentic record on this subject (alchemy) is an edict of Diocletian, about 300 years after Christ, ordering a diligent search to be made in Egypt for all the ancient books which treated of the art of making gold and silver, that they might be consigned to the flames. This edict necessarily presumes a certain antiquity to the pursuit; and fabulous history has recorded Solomon, Pythagoras, and Hermes among its distinguished votaries.

There is no conversation more boring than the one where everybody agrees.

The utmost possible regarding an individual is a statement as to some order of probability about the future. Heisenberg's principle has been seized upon as a basis for wild statements to the effect that the doctrine of arbitrary free will and totally uncaused activity are now scientifically substantiated. Its actual force and significance is generalization of the idea that the individual is a temporal career whose future cannot logically be deduced from its past.

It is certain that we cannot escape anguish, for we are anguish.

In an ideal University, as I conceive it, a man should be able to obtain instruction in all forms of knowledge, and discipline in the use of all the methods by which knowledge is obtained. In such a University, the force of living example should fire the student with a noble ambition to emulate the learning of learned men, and to follow in the footsteps of the explorers of new fields of knowledge. And the very air he breathes should be charged with that enthusiasm for truth, that fanaticism of veracity, which is a greater possession than much learning; a nobler gift than the power of increasing knowledge; by so much greater and nobler than these, as the moral nature of man is greater than the intellectual; for veracity is the heart of morality.

Self-interest, or rather self-love, or egoism, has been more plausibly substituted as the basis of morality. But I consider our relations with others as constituting the boundaries of morality. With ourselves, we stand on the ground of identity, not of relation, which last, requiring two subjects, excludes self-love confined to a single one. To ourselves, in strict language, we can owe no duties, obligation requiring also two parties. Self-love, therefore, is no part of morality. Indeed, it is exactly its counterpart.

But no mental action seems necessary or invariable in its character. In whatever manner the mind has reacted under a given sensation, in that manner it is the more likely to react again; were this, however, an absolute necessity, habits would become wooden and ineradicable, and no room being left for the formulation of new habits, intellectual life would come to a speedy close. Thus, the uncertainty of the mental law is no mere defect of it, but is on the contrary of its essence. The truth is, the mind is not subject to "law," in the same rigid sense that matter is. It only experiences gentle forces which merely render it more likely to act a given way than it otherwise would be. There always remains a certain amount of arbitrary spontaneity in its action, without which it would be dead.

Marx shared with economists then and since the inability to make his concepts include innovational processes. It is one thing to spot a new product but quite another to observe the invisible new environments generated by the action of the product on a variety of pre-existing social grounds.

It is difficulties that show what men are.

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.

The divine is God's concern; the human, man's. My concern is neither the divine nor the human, not the true, good, just, free, etc., but solely what is mine, and it is not a general one, but is - unique, as I am unique. Nothing is more to me than myself!

The very proclaimers of "America first" have long before this betrayed the fundamental principles of real Americanism...the other truly great Americans who aimed to make of this country a haven of refuge, who hoped that all the disinherited and oppressed people in coming to these shores would give character, quality and meaning to the country.

We cannot observe external things without some degree of Thought; nor can we reflect upon our Thoughts, without being influenced in the course of our reflection by the Things which we have observed.

Objectivity may also be defined as freedom: the objective individual is bound by no commitments which could prejudice his perception, understanding, and evaluation of the given.

He that is not with me is against me: and he that gathereth not with me scattereth.

There are as many nights as days, and the one is just as long as the other in the year's course. Even a happy life cannot be without a measure of darkness, and the word "happy" would lose its meaning if it were not balanced by sadness.

Either one defines "personality" and "individuality" in terms of their possibilities within the established form of civilization, in which case their realization is for the vast majority tantamount to successful adjustment. Or one defines them in terms of their transcending content, including their socially denied potentialities beyond (and beneath) their actual existence; in this case, their realization would imply transgression, beyond the established form of civilization, to radically new modes of "personality" and "individuality" incompatible with the prevailing ones. Today, this would mean "curing" the patient to become a rebel or (which is saying the same thing) a martyr.

Freud's fanciful pseudo-explanations (precisely because they are brilliant) perform a disservice. (Now any ass has these pictures available to use in "explaining" symptoms of an illness).

By relieving the brain of all unnecessary work, a good notation sets it free to concentrate on more advanced problems, and in effect increases the mental power of the race..

All that is not thought is pure nothingness; since we can think only thought and all the words we use to speak of things can express only thoughts, to say there is something other than thought, is therefore an affirmation which can have no meaning.And yet-strange contradiction for those who believe in time-geologic history shows us that life is only a short episode between two eternities of death, and that, even in this episode, conscious thought has lasted and will last only a moment. Thought is only a gleam in the midst of a long night. But it is this gleam which is everything.

Life creates itself in delirium and is undone in ennui.

If a due participation of office is a matter of right, how are vacancies to be obtained? Those by death are few; by resignation, none.

That there is no such thing as what philosophers call material substance, I am seriously persuaded: but if I were made to see any thing absurd or skeptical in this, I should then have the same reason to renounce this, that I imagine I have now to reject the contrary opinion.

They might need a preparatory discourse on the text of 'prove all things, hold fast that which is good,' in order to unlearn the lesson that reason is an unlawful guide in religion. They might startle on being first awaked from the dreams of the night, but they would rub their eyes at once, and look the spectres boldly in the face.

Wherever you are it is your own friends who make your world.

Dead of night. No one, nothing but the society of the moments. Each pretends to keep us company, then escapes - desertion after desertion.

What is food to one, is to others bitter poison.

But if it bee well considered, The praise of Ancient Authors, proceeds not from the reverence of the Dead, but from the competition and mutual envy of the Living.

True, the law is sacred to the bourgeois, for it is his own composition, enacted with his consent, and for his benefit and protection. He knows that, even if an individual law should injure him, the whole fabric protects his interests; and more than all, the sanctity of the law, the sacredness of order as established by the active will of one part of society, and the passive acceptance of the other, is the strongest support of his social position. Because the English bourgeois finds himself reproduced in his law, as he does in his God, the policeman's truncheon which, in a certain measure, is his own club, has for him a wonderfully soothing power. But for the working-man quite otherwise! The working-man knows too well, has learned from too oft-repeated experience, that the law is a rod which the bourgeois has prepared for him; and when he is not compelled to do so, he never appeals to the law.

There's something that remains barbarous in educated people, and lately I've more and more had the feeling that we are nonwondering primitives. And why is it that we no longer marvel at these technological miracles? They've become the external facts of every life. We've all been to the university, we've had introductory courses in everything, and therefore we have persuaded ourselves that if we had the time to apply ourselves to these scientific marvels, we would understand them. But of course that's an illusion. It couldn't happen. Even among people who have had careers in science. They know no more about how it all works than we do. So we are in the position of savage men who, however, have been educated into believing that they are capable of understanding everything. Not that we actually do understand, but that we have the capacity.

"They have an engine called the Press whereby the people are deceived."

Libraries are as the shrine where all the relics of the ancient saints, full of true virtue, and that without delusion or imposture, are preserved and reposed.

As long as the aristocracy is healthy, the name of the sovereign sacred to it, and it loves the monarchy passionately, the State is unshakeable, whatever be the qualities of the king. But once it loses its greatness, its pride, its energy, its faith, the spirit withdraws, the monarchy is dead, and its cadaver is left to the worms.

The restoration of our world-view can come only as a result of inexorably truth-loving and recklessly courageous thought. Such thinking alone is mature enough to learn by experience how the rational, when it thinks itself out to a conclusion, passes necessarily over into the non-rational. World- and life-affirmation and ethics are non-rational. They are not justified by any corresponding knowledge of the nature of the world, but are the disposition in which, through the inner compulsion of our will-to-live, we determine our relation to the world. What the activity of this disposition of ours means in the evolution of the world, we do not know. Nor can we regulate this activity from outside; we must leave entirely to each individual its shaping and its extension. From every point of view, then, world- and life-affirmation and ethics are non-rational, and we must have the courage to admit it.

To explain all nature is too difficult a task for any one man or even for any one age. 'Tis much better to do a little with certainty, & leave the rest for others that come after you, than to explain all things by conjecture without making sure of any thing.

Beat a dog once and you only have to show him the whip.

Perhaps then we must begin with such facts as are known to us from individual experience. It is necessary therefore that the person who is to study, with any tolerable chance of profit, the principles of nobleness and justice and politics generally, should have received a good moral training.

I am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.

That which exercises reason is more excellent than that which does not exercise reason; there is nothing more excellent than the universe, therefore the universe exercises reason.

You do not attain to knowledge by remaining on the shore and watching the foaming waves, you must make the venture and cast yourself in, you must swim, alert and with all your force, even if a moment comes when you think you are losing consciousness; in this way, and in no other, do you reach anthropological insight.

Kripke tries to sober us up by denying that meaning determines reference. Rather, we name things by confronting them and baptising them, not by creating them out of a list of qualities. Names are not, pace Russell, shorthand for such lists. They are not abbreviations for descriptions, but (in Kripke's coinage) 'rigid designators' - that is, they would name the same things in any possible world, including worlds in which their bearers did not have the properties we, in this world, use to identify them.

The strengthening of behavior which results from reinforcement is appropriately called "conditioning". In operant conditioning we "strengthen" an operant in the sense of making a response more probable or, in actual fact, more frequent.

Plants are Children of the Earth; we are Children of the Æther. Our Lungs are properly our Root; we live, when we breathe; we begin our life with breathing.
