But it is better to assume principles less in number and finite, as Empedocles makes them to be. All philosophers... make principles to be contraries... (for Parmenides makes principles to be hot and cold, and these he demominates fire and earth) as those who introduce as principles the rare and the dense. But Democritus makes the principles to be the solid and the void; of which the former, he says, has the relation of being, and the latter of non-being. ...it is necessary that principles should be neither produced from each other, nor from other things; and that from these all things should be generated. But these requisites are inherent in the first contraries: for, because they are first, they are not from other things; and because they are contraries, they are not from each other.

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.

This fighting-shy of every obligation partly explains the phenomenon, half ridiculous, half disgraceful, Of the setting-up in our days of the platform of "youth" as youth. ... In comic fashion people call themselves "young," because they have heard that youth has more rights than obligations, since it can put off the fulfilment of these latter to the Greek Kalends of maturity. ...[T]he astounding thing at present is that these take it as an effective right precisely in order to claim for themselves all those other rights which only belong to the man who has already done something.

The vices respectively fall short of or exceed what is right in both passions and actions, while virtue both finds and chooses that which is intermediate.

I will not accept boundaries; appearances cannot contain me; I choke! To bleed in this agony, and to live it profoundly, is the second duty. The mind is patient and adjusts itself, it likes to play; but the heart grows savage and will not condescend to play; it stifles and rushes to tear apart the nets of necessity.

All repressed passion produces its counter-passion which is as malevolent as the natural passion would be beneficial.

Since Sputnik there is no Nature. Nature is an item contained in a man-made environment of satellites and information.

Existence is illusory and it is eternal.

If, while hurrying ostensibly to the temple of truth, we hand the reins over to our personal interests which look aside at very different guiding stars, for instance at the tastes and foibles of our contemporaries, at the established religion, but in particular at the hints and suggestions of those at the head of affairs, then how shall we ever reach the high, precipitous, bare rock whereon stands the temple of truth?

There's far too much generalization now about rural America. Conservatives and corporations have had their eye on rural America all along. And they've been turning it into money as fast as they can, which is to say destroying the land and the people...

To preserve the freedom of the human mind then and freedom of the press, every spirit should be ready to devote itself to martyrdom; for as long as we may think as we will, and speak as we think, the condition of man will proceed in improvement. The generation which is going off the stage has deserved well of mankind for the struggles it has made, and for having arrested the course of despotism which had overwhelmed the world for thousands and thousands of years. If there seems to be danger that the ground they have gained will be lost again, that danger comes from the generation your contemporary. But that the enthusiasm which characterizes youth should lift its parricide hands against freedom and science would be such a monstrous phenomenon as I cannot place among possible things in this age and country.

It is difficult to speak of the universal specifically.

Only lay down true principles, and adhere to them inflexibly. Do not be frightened into their surrender by the alarms of the timid, or the croakings of wealth against the ascendency of the people.

The task of power is to transform the always possible 'no' into a 'yes.'

So we do sometimes think because it has been found to pay.

I can prove now, for instance, that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, "Here is one hand," and adding, as I make a certain gesture with the left, "and here is another." And if, by doing this, I have proved ipso facto the existence of external things, you will all see that I can also do it now in numbers of other ways: there is no need to multiply examples.

The flesh receives as unlimited the limits of pleasure; and to provide it requires unlimited time. But the mind, intellectually grasping what the end and limit of the flesh is, and banishing the terrors of the future, procures a complete and perfect life, and we have no longer any need of unlimited time. Nevertheless the mind does not shun pleasure, and even when circumstances make death imminent, the mind does not lack enjoyment of the best life.

Either everything is illusion, nature as well as revelation, or experience alone can explain faith.

Out-of-date theories are not in principle unscientific because they have been discarded. That choice, however, makes it difficult to see scientific development as a process of accretion.

False opinions are like false money, struck first of all by guilty men and thereafter circulated by honest people who perpetuate the crime without knowing what they are doing. Original text:Les fausses opinions ressemblent à la fausse monnaie qui est frappée d'abord par de grands coupables et dépensée ensuite par d'honnêtes gens qui perpétuent le crime sans savoir ce qu'ils font.

A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

I think I can hardly overrate the malignity of the principles of Protestant ascendancy, as they affect Ireland; or of Indianism, as they affect these countries, and as they affect Asia; or of Jacobinism, as they affect all Europe, and the state of human society itself. The last is the greatest evil.

Nothing can be preserved that is not good.

Much reading after a certain age diverts the mind from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking, just as the man who spends too much time in the theaters is apt to be content with living vicariously instead of living his own life.

To say that the activity of science and art helps humanity's progress, if by that activity we mean the activity which now calls itself by those names, is as though one said that the clumsy, obstructive splashing of oars in a boat moving down stream assists the boat's progress. It only hinders it... The proof of this is seen in the confession made by men of science that the achievements of the arts and sciences are inaccessible to the labouring masses on account of the unequal distribution of wealth.

If by religion, we are understand sectarian dogmas, in which no two of them agree, then your exclamation on that hypothesis is just, "that this would be the best of all possible worlds, if there were no religion in it." But if the moral precepts, innate in man, and made a part of his physical constitution, as necessary for a social being, if the sublime doctrines of philanthropism and deism taught us by Jesus of Nazareth, in which all agree, constitute true religion, then, without it, this would be, as you again say, "something not fit to be named, even indeed, a hell."

The notion of nothingness is not characteristic of laboring humanity: those who toil have neither time nor inclination to weigh their dust; they resign themselves to the difficulties or the doltishness of fate; they hope: hope is a slave's virtue.

Stop Traveller! Near this place lieth John Locke. If you ask what kind of a man he was, he answers that he lived content with his own small fortune. Bred a scholar he made his learning subservient only to the cause of truth. This thou will learn from his writings, which will show thee everything else concerning him, with greater truth, than the suspect praises of an epitaph. His virtues, indeed, if he had any, were too little for him to propose as matter of praise to himself, or as an example to thee. Let his vices be buried together. As to an example of manners, if you seek that, you have it in the Gospels; of vices, to wish you have one nowhere; if mortality, certainly, (and may it profit thee), thou hast one here and everywhere.

Love with delight discourses in my mind Upon my lady's admirable gifts...Beyond the range of human intellect.

The primary error of the advocates of land nationalization is in their confusion of equal rights with joint rights, and in their consequent failure to realize the nature and meaning of economic rent... In truth the right to the use of land is not a joint or common right, but an equal right; the joint or common right is to rent, in the economic sense of the term. Therefore it is not necessary for the state to take land, it is only necessary for it to take rent. This taking by the commonalty of what is of common right, would of itself secure equality in what is of equal right - for since the holding of land could be profitable only to the user, there would be no inducement for any one to hold land that he could not adequately use, and monopolization being ended no one who wanted to use land would have any difficulty in finding it.

Speculative philosophy as the realisation of God is the positing of God, and at the same time his cancellation or negation; theism and at the same time atheism: for God - in the sense of theology - is God only as long as he is taken to be a being distinguished from and independent of the being of man as well as of nature. The theism that as the positing of God is simultaneously his negation or, conversely, as the negation of God equally his affirmation, is pantheism. Theological theism - that is, theism properly speaking - is nothing other than imaginary pantheism which itself is nothing other than real and true theism.

A physicist looks for causes; that does not necessarily imply that there are causes everywhere. A man may look for gold without assuming that there is gold everywhere; if he finds gold, well and good, if he doesn't he's had bad luck. The same is true when the physicists look for causes.

Democracy is still upon its trial. The civic genius of our people is its only bulwark.

So dazzling was the spread of constellations that it had the impact of a vision, of some hidden insight. I drove home saying to myself: The dead, too, are like this, blazing within us - invisibly.

Nothing in all literature is so depressing as the "Dissertations" of the slave [Epictetus], unless it be the "Meditations" of the Emperor [Marcus Aurelius] ...[after some excerpts from the two books]..... In such passages we feel the proximity of Christianity and its dauntless martyrs; indeed were not the Christian ethic of self-denial, the Christian political ideal of an almost communistic brotherhood of man, and the Christian eschatology of the final conflagration of all the world, fragments of Stoic doctrine floating on the stream of thought? In Epictetus the Greco-Roman soul has lost its paganism, and is ready for a new faith".

We Jews have been too adaptable. We have been too eager to sacrifice our idiosyncrasies for the sake of social conformity. ... Even in modern civilization, the Jew is most happy if he remains a Jew.

Every intellectual effort sets us apart from the commonplace, and leads us by hidden and difficult paths to secluded spots where we find ourselves amid unaccustomed thoughts.

All parties seem to be agreed on one point, that the dialects commonly spoken among the natives of this part of India contain neither literary nor scientific information, and are moreover so poor and rude that, until they are enriched from some other quarter, it will not be easy to translate any valuable work into them.

It is said in the Book of Poetry, "In silence is the offering presented, and the spirit approached to; there is not the slightest contention." Therefore the superior man does not use rewards, and the people are stimulated to virtue. He does not show anger, and the people are awed more than by hatchets and battle-axes.

The heart of Christianity is a myth which is also a fact.

We believe that the very beginning and end of salvation, and the sum of Christianity, consists of faith in Christ, who by His blood alone, and not by any works of ours, has put away sin, and destroyed the power of death.

The world is nothing but 'world-as-meaning.'

A precise language awaits a completed metaphysics.

Their principles always go to the extreme. They who go with the principles of the ancient Whigs, which are those contained in Mr. Burke's book, never can go too far. ... The opinions maintained in that book never can lead to an extreme, because their foundation is laid in an opposition to extremes.
