By convention sweet is sweet, bitter is bitter, hot is hot, cold is cold, color is color; but in truth there are only atoms and the void.

History, is a conscious, self-mediating process - Spirit emptied out into Time; but this externalization, this kenosis, is equally an externalization of itself; the negative is the negative of itself. ... Thus absorbed in itself, it is sunk in the night of its self-consciousness; but in that night its vanished outer existence is perserved, and this transformed existence - the former one, but now reborn of the Spirit's knowledge - is the new existence, a new world and a new shape of Spirit.

"And I say also this. I do not think the forest would be so bright, nor the water so warm, nor love so sweet, if there were no danger in the lakes."

What are the earth and all its interests beside the deep surmise which pierces and scatters them?

Every plant, which my heavenly Father hath not planted, shall be rooted up. Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch. 15:13-14 (KJV)

Malice sucks up the greatest part of its own venom, and poisons itself.

The irony here is quite remarkable: Hobbes, who would later spend years publishing and defending numerous attempts to square the circle, published his first mathematical work as part of a campaign to silence an old circle squarer. Indeed, less than a decade after his participation in Pell's battle with Longomontanus, Hobbes would find himself involved in a prolonged and bitter controversy that centered on his claims to have squared the circle, and he would go to his grave insisting that he had solved this ancient geometrical problem. Douglas M. Jesseph, Squaring the Circle: The War Between Hobbes and Wallis

Kant [...] stated that he had "found it necessary to deny knowledge [...] to make room for faith," but all he had "denied" was knowledge of things that are unknowable, and he had not made room for faith but for thought.

To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one have already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our dis-beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of their possessor's body at the time.

Manufacture was all the time sheltered by protective duties in the hoe market, by monopolies in the colonial market, and broad as much as possible by differential duties.

It is no one's privilege to despise another. It is only a hard-won right after long experience.

Figure to yourself the mixture of surprise and delight which has this instant been poured into my mind by the sound of my name, as uttered by you, in the speech just read to me out of the Morning Herald... By one and the same man, not only Parliamentary Reform, but Law Reform advocated. Advocated? and by what man? By one who, in the vulgar sense of profit and loss, has nothing to gain by it... Yes, only from Ireland could such self-sacrifice come; nowhere else: least of all in England, cold, selfish, priest-ridden, lawyer-ridden, lord-ridden, squire-ridden, soldier-ridden England, could any approach to it be found.

The only man for whom Hitler had "unqualified respect" was "Stalin the genius," and while in the case of Stalin and the Russian regime we do not... have the rich documentary material that is available for Germany, we nevertheless know since Khrushchev's speech before the Twentieth Party Congress that Stalin trusted only one man and that was Hitler.

I will now confess my own utopia. I devoutly believe in the reign of peace and in the gradual advent of some sort of socialistic equilibrium. The fatalistic view of the war function is to me nonsense, for I know that war-making is due to definite motives and subject to prudential checks and reasonable criticisms, just like any other form of enterprise. And when whole nations are the armies, and the science of destruction vies in intellectual refinement with the science of production, I see that war becomes absurd and impossible from its own monstrosity. Extravagant ambitions will have to be replaced by reasonable claims, and nations must make common cause against them.

Revolutions are the locomotives of history.

Friends are not primarily absorbed in each other. It is when we are doing things together that friendship springs up - painting, sailing ships, praying, philosophizing, fighting shoulder to shoulder. Friends look in the same direction. Lovers look at each other - that is, in opposite directions. To transfer bodily all that belongs to one relationship into the other is blundering.

We are not so absurd as to propose that the teacher should not set forth his own opinions as the true ones and exert his utmost powers to exhibit their truth in the strongest light. To abstain from this would be to nourish the worst intellectual habit of all, that of not finding, and not looking for, certainty in any teacher. But the teacher himself should not be held to any creed; nor should the question be whether his own opinions are the true ones, but whether he is well instructed in those of other people, and, in enforcing his own, states the arguments for all conflicting opinions fairly.

Creatures extremely low in the intellectual scale may have conception. All that is required is that they should recognize the same experience again. A polyp would be a conceptual thinker if a feeling of 'Hello! thingumbob again!' ever flitted through its mind.

By the removal of the unnecessary mouths, and by extracting from the farmer the full value of the farm, a greater surplus, or what is the same thing, the price of a greater surplus, was obtained for the proprietor...

The state is primarily an organization for killing foreigners.

Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end, an end which it was already but too easy to arrive at.

The end cannot justify the means for the simple and obvious reason that the means employed determine the nature of the ends produced.

Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven. 16:17-19 (KJV)

But yet they that have no Science, are in better, and nobler condition with their naturall Prudence; than men, that by their mis-reasoning, or by trusting them that reason wrong, fall upon false and absurd generall rules.

Look now, this is the starting point of philosophy: the recognition that different people have conflicting opinions, the rejection of mere opinion so that it comes to be viewed with mistrust, an investigation of opinion to determine whether it is rightly held, and the discovery of a standard of judgement, comparable to the balance that we have devised for the determining of weights, or the carpenter's rule for determining whether things are straight or crooked.

Cato instigated the magistrates to punish all offenders, saying that they that did not prevent crimes when they might, encouraged them. Of young men, he liked them that blushed better than those who looked pale.

All human knowledge begins with intuitions, proceeds from thence to concepts, and ends with ideas.

This right which you have, is not founded any more than his upon any quality or any merit in yourself which renders you worthy of it. Your soul and your body are, of themselves, indifferent to the state of boatman or that of duke; and there is no natural bond that attaches them to one condition rather than to another.

Disobedience is the true foundation of liberty. The obedient must be slaves.

Zeus, the god of gods, who rules according to law, and is able to see into such things, perceiving that an honourable race was in a woeful plight, and wanting to inflict punishment on them, that they might be chastened and improve, collected all the gods into their most holy habitation, which, being placed in the centre of the world, beholds all created things.

My cares and my inquiries are for decency and truth, and in this I am wholly occupied.

[Mortals] say of some temporal suffering, "No future bliss can make up for it," not knowing Heaven, once attained, will work backwards and turn even that agony into a glory. And of some sinful pleasure they say "Let me have but this and I'll take the consequences": little dreaming how damnation will spread back and back into their past and contaminate the pleasure of the sin. Both processes begin even before death.

No man is free who is not master of himself.

The trade of governing has always been monopolized by the most ignorant and the most rascally individuals of mankind.

With men this is impossible; but with God all things are possible. 19:26 (KJV)

If the world were clear, art would not exist.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride or laziness of mind. 

Freedom of opinion can only exist when the government thinks itself secure...

...they cudgel their brains with absurd questions, such as, for instance, why God did not make the world many centuries earlier. They persuade themselves that it is easy to conceive, to be sure, how God may discern what is present, that is, what is actual in the time in which he is, but how He may foresee what is future, that is, what is actual in the time in which He is not yet, they deem an intellectual difficulty; as if the existence of the Necessary Being descended through all the moments of an imaginary time, and, having already exhausted a part of His duration, saw before Him the eternity He was yet to live simultaneously with the present events of the world. All these difficulties upon proper insight into the notion of time vanish like smoke.

Generally speaking there is no irreducible taste or inclination. They all represent a certain appropriative choice of being. It is up to existential psychoanalysis to compare and classify them. Ontology abandons us here; it has merely enabled us to determine the ultimate ends of human reality, its fundamental possibilities, and the value which haunts it.

Not only must philosophy be in agreement with our empirical knowledge of Nature, but the origin and formation of the Philosophy of Nature presupposes and is conditioned by empirical physics. However, the course of a science's origin and the preliminaries of its construction are one thing, while the science itself is another. In the latter, the former can no longer appear as the foundation of the science; here, the foundation must be the necessity of the Concept.

Whilst in speaking of human things, we say that it is necessary to know them before we can love them...the saints on the contrary say in speaking of divine things that it is necessary to love them in order to know them, and that we only enter truth through charity.

Custom renders love attractive; for that which is struck by oft-repeated blows however lightly, yet after long course of time is overpowered and gives way. See you not too that drops of water falling on rocks after long course of time scoop a hole through these rocks?

People don't stop things they enjoy doing just because they reach a certain age. They don't stop playing tennis just because they turn 40, they don't stop with sex just because they turn 40; they keep it up as long as they can if they enjoy it, and learning will be the same thing.

She [virtue] requires a rough and stormy passage; she will have either outward difficulties to wrestle with, ... or internal difficulties.

... happiness is not an ideal of reason, but of imagination, resting on merely empirical grounds…

To the divine providence it has seemed good to prepare in the world to come for the righteous good things, which the unrighteous shall not enjoy; and for the wicked evil things, by which the good shall not be tormented. But as for the good things of this life, and its ills, God has willed that these should be common to both; that we might not too eagerly covet the things which wicked men are seen equally to enjoy, nor shrink with an unseemly fear from the ills which even good men often suffer. There is, too, a very great difference in the purpose served both by those events which we call adverse and those called prosperous. For the good man is neither uplifted with the good things of time, nor broken by its ills; but the wicked man, because he is corrupted by this world's happiness, feels himself punished by its unhappiness.

It is better to fight with a few good men against all the wicked, than with many wicked men against a few good men.

Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it.

I have no patience with those who say that sexual excitement is shameful and that venereal stimuli have their origin not in nature, but in sin. Nothing is so far from the truth. As if marriage, whose function cannot be fulfilled without these incitements, did not rise above blame. In other living creatures, where do these incitements come from? From nature or from sin? From nature, of course. It must borne in mind that in the apetites of the body there is very little difference between man and other living creatures. Finally, we defile by our imagination what of its own nature is fair and holy. If we were willing to evaluate things not according to the opinion of the crowd, but according to nature itself, how is it less repulsive to eat, chew, digest, evacuate, and sleep after the fashion of dumb animals, than to enjoy lawful and permitted carnal relations?
