Notwithstanding their attacks on the basic conception of rationalism, on synthetic a priori judgments, that is, material propositions that cannot be contradicted by any experience, the empiricist posits the forms of being as constant.

The third argument, enclosing and defending the other two, consists in the development of those principles of logic according to which the humble argument is the first stage of a scientific inquiry into the origin of the three Universes, but of an inquiry which produces, not merely scientific belief, which is always provisional, but also a living, practical belief, logically justified in crossing the Rubicon with all the freightage of eternity.

A man of intellect is like an artist who gives a concert without any help from anyone else, playing on a single instrument - a piano, say, which is a little orchestra in itself. Such a man is a little world in himself; and the effect produced by various instruments together, he produces single-handed, in the unity of his own consciousness. Like the piano, he has no place in a symphony; he is a soloist and performs by himself - in solitude, it may be; or if in the company with other instruments, only as principal; or for setting the tone, as in singing.

The techniques of the practitioner are usually called 'synthetic'. He designs by organizing known principles and devices into larger systems.

What a stupendous, what an incomprehensible machine is man! Who can endure toil, famine, stripes, imprisonment and death itself in vindication of his own liberty, and the next moment, be deaf to all those motives whose powers supported him through his trial, and inflict on his fellow men a bondage, one hour of which is fraught with more misery than ages of that which he rose in rebellion to oppose.

It happens that the stage sets collapse. Rising, streetcar, four hours in the office or the factory, meal, streetcar, four hours of work, meal, sleep and Monday Tuesday Wednesday Thursday Friday and Saturday according to the same rhythm this path is easily followed most of the time. But one day the "why" arises and everything begins in that weariness tinged with amazement.

Remember that what pulls the strings is the force hidden within; there lies the power to persuade, there the life,-there, if one must speak out, the real man.

All of those who are "without" - without employment, without residence, without housing - are really excluded only in part.

Lying and guile need only to be revealed and recognized to be undone. When once lying is recognized as such, it needs no second stroke; it falls of itself and vanishes in shame.

Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

Earth proudly wears the Parthenon As the best gem upon her zone.

Thought is something limitless and independent, and has been mixed with no thing but is alone by itself. ... What was mingled with it would have prevented it from having power over anything in the way in which it does. ... For it is the finest of all things and the purest.

It is only natural that I should constantly have revolved in my mind the question of the relationship of the symbolism of the unconscious to Christianity as well as to other religions. Not only do I leave the door open for the Christian message, but I consider it of central importance for Western man. It needs, however, to be seen in a new light, in accordance with the changes wrought by the contemporary spirit.

The great tragedy of Science - the slaying of a beautiful hypothesis by an ugly fact.

The most violent revolutions in an individual's beliefs leave most of his old order standing. Time and space, cause and effect, nature and history, and one's own biography remain untouched. New truth is always a go-between, a smoother-over of transitions. It marries old opinion to new fact so as ever to show a minimum of jolt, a maximum of continuity.

The functional regions of the brain which subserve physical agony, the "pain centres", and the mainly limbic substrates of emotion, appear in phylogenetic terms to be remarkably constant in the vertebrate line. The neural pathways involving serotonin, the periaquaductal grey matter, bradykinin, dynorphin, ATP receptors, the major opioid families, substance P etc all existed long before hominids walked the earth. Not merely is the biochemistry of suffering disturbingly similar where not effectively type-identical across a wide spectrum of vertebrate (and even some invertebrate) species. It is at least possible that members of any species whose members have more pain cells exhibiting greater synaptic density than humans sometimes suffer more atrociously than we do, whatever their notional "intelligence".

This reasonable moderator, and equal piece of justice, Death.

If a false thought is so much as expressed boldly and clearly, a great deal has already been gained.

Malthus's population principle was quite as much a banner, and a point of union among us, as any opinion specially belonging to Bentham. This great doctrine, originally brought forward as an argument against the indefinite improvability of human affairs, we took up with ardent zeal in the contrary sense, as indicating the sole means of realizing that improvability by securing full employment at high wages to the whole labouring population through a voluntary restriction of the increase of their numbers.

Students have powerful images of what a perfect body is and pursue it incessantly. But deprived of literary guidance, they no longer have any image of a perfect soul, and hence do not long to have one.

I do not understand! I understand nothing! I cannot understand nor do I want to understand! I want to believe! To Believe!

You cannot endow even the best machine with initiative; the jolliest steam-roller will not plant flowers.

To understand this for sense it is not required that a man should be a geometrician or a logician, but that he should be mad. On the proposition that the volume generated by revolving the region under 1/x from 1 to infinity has finite volume.

The metaphysical apologia at least betrayed the injustice of the established order through the incongruence of concept and reality. The impartiality of scientific language deprived what was powerless of the strength to make itself heard and merely provided the existing order with a neutral sign for itself. Such neutrality is more metaphysical than metaphysics.

I deny that anyone knows, or can know, the nature of the two sexes, as long as they have only been seen in their present relation to one another. If men had ever been found in society without women, or women without men, or if there had been a society of men and women in which the women were not under the control of the men, something might have been positively known about the mental and moral differences which may be inherent in the nature of each. What is now called the nature of women is an eminently artificial thing - the result of forced repression in some directions, unnatural stimulation in others.

Every man has some reminiscences which he would not tell to everyone, but only to his friends. He has others which he would not reveal even to his friends, but only to himself, and that in secret. But finally there are still others which a man is even afraid to tell himself, and every decent man has a considerable number of such things stored away. That is, one can even say that the more decent he is, the greater the number of such things in his mind.

Americans cleave to the things of this world as if assured that they will never die,... They clutch everything but hold nothing fast, and so lose grip as they hurry after some new delight. ... Death steps in in the end and stops him before he has grown tired of this futile pursuit of that complete felicity which always escapes him. At first sight there is something astonishing in this spectacle of so many lucky men restless in the midst of abundance. But it is a spectacle as old as the world; all that is new is to see a whole people performing in it.

I dare affirm in knowledge of nature, that a little natural philosophy, and the first entrance into it, doth dispose the opinion to atheism; but on the other side, much natural philosophy and wading deep into it, will bring about men's minds to religion; wherefore atheism every way seems to be combined with folly and ignorance, seeing nothing can can be more justly allotted to be the saying of fools than this, "There is no God" Of Atheism.

The Book had in a high degree excited us to self-activity, which is the best effect of any book.

To affirm that humans thrive in many different ways is not to deny that there are universal human values. Nor is it to reject the claim that there should be universal human rights. It is to deny that universal values can only be fully realized in a universal regime. Human rights can be respected in a variety of regimes, liberal and otherwise. Universal human rights are not an ideal constitution for a single regime throughout the world, but a set of minimum standards for peaceful coexistence among regimes that will always remain different.

The friend, enemy, and combat concepts receive their real meaning precisely because they refer to the real possibility of physical killing. War follows from enmity. War is the existential negation of the enemy.

Every man is, no doubt, by nature, first and principally recommended to his own care; and as he is fitter to take care of himself than of any other person, it is fit and right that it should be so.

The popularity of the paranormal, oddly enough, might even be grounds for encouragement. I think that the appetite for mystery, the enthusiasm for that which we do not understand, is healthy and to be fostered. It is the same appetite which drives the best of true science, and it is an appetite which true science is best qualified to satisfy.

Every day should be passed as if it were to be our last.

We Americans claim to be a peace-loving people. We hate bloodshed; we are opposed to violence. Yet we go into spasms of joy over the possibility of projecting dynamite bombs from flying machines upon helpless citizens. We are ready to hang, electrocute, or lynch anyone, who, from economic necessity, will risk his own life in the attempt upon that of some industrial magnate. Yet our hearts swell with pride at the thought that America is becoming the most powerful nation on earth, and that it will eventually plant her iron foot on the necks of all other nations. Such is the logic of patriotism.

Love's great (and sole) originality is to make happiness indistinct from misery.

Courtiers don't take wagers against the king's skill.

Now to Some it appears not at all worth while to follow out the endless divisions of Nature; and moreover a dangerous undertaking, without fruit and issue. As we can never reach, say they, the absolutely smallest grain of material bodies, never find their simplest compartments, since all magnitude loses itself, forwards and backwards, in infinitude; so likewise is it with the species of bodies and powers; here too one comes on new species, new combinations, new appearances, even to infinitude. These seem only to stop, continue they, when our diligence tires; and so it is spending precious time with idle contemplations and tedious enumerations; and this becomes at last a true delirium, a real vertigo over the horrid Deep.

Since the science of nature is conversant with magnitudes, motion, and time, each of which must necessarily be either infinite or finite...we should speculate the infinite, and consider whether it is or not; and if it is what it is. ...All those who appear to have touched on a philosophy of this kind... consider it as a certain principle of beings. Some, indeed, as the Pythagoreans and Plato, consider it, per se, not as being an accident to any thing else, but as having an essential subsistence... the Pythagoreans... consider the infinite as subsisting in sensibles; for they do not make number to be separate; and they assert that what is beyond the heavens is infinite; but Plato says that beyond the heavens there is not any body, nor ideas, because these are no where: he affirms, however, that the infinite is both in sensibles, and in ideas. ...Plato establishes two infinities, viz. the great and the small.

...Lucretius talked epicureanism stoically (like Heine's Englishman taking his pleasures sadly), and concluded on his stren gospel of pleasure by committing suicide. His noble epic "on the Nature of Things", follows Epicurus in damning pleasure with faint praise. Almost contemporary with Caesar and Pompey, he lived in the midst of turmoil and alarms; his nervous pen is forever inditing prayers to tranquility and peace. One pictures him as a timid soul whose youth had been darkened with religious fears; for he never tires of telling his readers that there's no hell, except here, and there are no gods except gentlemanly ones who live in a garden of Epicurus in the clouds, and never intrude in the affairs of men.

By nature a philosopher is not in genius and disposition half so different from a street porter, as a mastiff is from a greyhound.

My idea of heaven is, eating pâté de foie gras to the sound of trumpets.

It is evident that this, among many other of the purposes of my father's scheme of education, could not have been accomplished if he had not carefully kept me from having any great amount of intercourse with other boys. He was earnestly bent upon my escaping not only the ordinary corrupting influence which boys exercise over boys, but the contagion of vulgar modes of thought and feeling; and for this he was willing that I should pay the price of inferiority in the accomplishments which schoolboys in all countries chiefly cultivate. The deficiencies in my education were principally in the things which boys learn from being turned out to shift for themselves, and from being brought together in large numbers.

By mortifying vanity we do ourselves no good. It is the want of interest in our life which produces it; by filling up that want of interest in our life we can alone remedy it. And, did we even see this, how can we make the difference? How obtain the interest which society declares she does not want, and we cannot want?

It appears to me to be indisputable that he who I am to-day derives, by a continuous series of states of consciousness, from him who was in my body twenty years ago. Memory is the basis of individual personality, just as tradition is the basis of the collective personality of a people. We live in memory, and our spiritual life is at bottom simply the effort of our memory to persist, to transform itself into hope, the effort of our past to transform itself into our future.

The sublime is excited in me by the great stoical doctrine, Obey thyself.

By capitulating to life, this world has betrayed nothingness. . . . I resign from movement, and from my dreams. Absence! You shall be my sole glory. . . . Let "desire" be forever stricken from the dictionary, and from the soul! I retreat before the dizzying farce of tomorrows. And if I still cling to a few hopes, I have lost forever the faculty of hoping.

The revolutionaries say: "The government organization is bad in this and that respect; it must be destroyed and replaced by this and that." But a Christian says: "I know nothing about the governmental organization, or in how far it is good or bad, and for the same reason I do not want to support it."
