Every other art,-as poetry, music, painting,-may be practised without the process showing forth the rules according to which it is conducted ;-but in the self-cognizant art of the philosopher, no step can be taken without declaring the grounds upon which it proceeds.

It is somewhat strange to me, that neither the Spagyrists themselves, nor yet their Adversaries, should have taken notice that Chymists have rather supposed than evinced, that the Analysis of bodies by fire, or even that at least some Analysis is the onely instrument of investigating what Ingredients mixt bodies are made up of, since in divers cases That may be discovered by Composition as well as by Resolution; as it may appear, that Vitriol consists of metalline parts (whether Martial, or Venereal, or both) associated by Coagulation with acid ones, one may, I say, discover this as well by making true Vitriol with Spirit (improperly called Oil) of Sulphur, or that of Salt, as by distilling or Resolving Vitriol by the fire.

It is your concern when your neighbor's wall is on fire.

It might be plausibly maintained, that in almost every one of the leading controversies, past or present, in social philosophy, both sides were in the right in what they affirmed, though wrong in what they denied.

The universal view melts things into a blur.

None can be an impartial or wise observer of human life but from the vantage ground of what we should call voluntary poverty.

Reading the Socratic dialogues one has the feeling: what a frightful waste of time! What's the point of these arguments that prove nothing and clarify nothing?

It really is worth the trouble to invent a new symbol if we can thus remove not a few logical difficulties and ensure the rigour of the proofs. But many mathematicians seem to have so little feeling for logical purity and accuracy that they will use a word to mean three or four different things, sooner than make the frightful decision to invent a new word.

Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

Hope is the only good that is common to all men; those who have nothing else possess hope still.

When television screens had only rare images of black folks, black people were more critically vigilant about these representations. Even when blackness was represented 'positiviely,' as it was in early black television shows like Julia, which focused on the life of a black nurse, the beauty standard was a reflection of white supremacist aesthetics.

What is left when honor is lost?

The natural effort of every individual to better his own condition, when suffered to exert itself with freedom and security is so powerful a principle that it is alone, and without any assistance, not only capable of carrying on the society to wealth and prosperity, but of surmounting a hundred impertinent obstructions with which the folly of human laws too often incumbers its operations; though the effect of these obstructions is always more or less either to encroach upon its freedom, or to diminish its security.

The real issue is not whether two and two make four or whether two and two make five, but whether life advances by men who love words or men who love living.

We must needs believe with faith, whatever counsels reason may give us, that in the depths of our own bodies, in animals, in plants, in rocks, in everything that lives, in all the Universe, there is a spirit that strives to know itself, to acquire consciousness of itself, to be itself - for to be oneself is to know oneself - to be pure spirit; and since it can only achieve this by means of the body, by means of matter, it creates and makes use of matter at the same time that it remains a prisoner of it.

Many people think they are thinking when they are merely rearranging their prejudices. 

Truth and falsity are the most fundamental terms of rational criticism, and any adequate philosophy must give some account of these, or failing that, show that they can be dispensed with.

Never unreal, Pain is a challenge to the universal fiction. What luck to be the only sensation granted a content, if not a meaning!

Furthermore, how will you endure the Romanists' terrible idolatries? It was not enough that they venerated the saints and praised God in them, but they actually made them into gods. They put that noble child, the mother Mary, right into the place of Christ. They fashioned Christ into a judge and thus devised a tyrant for anguished consciences, so that all comfort and confidence was transferred from Christ to Mary, and then everyone turned from Christ to his particular saint. Can anyone deny this? Is it not true?

Existential envy which is directed against the other person's very nature, is the strongest source of ressentiment. It is as if it whispers continually: "I can forgive everything, but not that you are- that you are what you are-that I am not what you are-indeed that I am not you." This form of envy strips the opponent of his very existence, for this existence as such is felt to be a "pressure," a "reproach," and an unbearable humiliation. In the lives of great men there are always critical periods of instability, in which they alternately envy and try to love those whose merits they cannot but esteem. Only gradually, one of these attitudes will predominate. Here lies the meaning of Goethe's reflection that "against another's great merits, there is no remedy but love."

I suddenly dreamt that I picked up the revolver and aimed it straight at my heart - my heart, and not my head; and I had determined beforehand to fire at my head, at my right temple. After aiming at my chest I waited a second or two, and suddenly my candle, my table, and the wall in front of me began moving and heaving. I made haste to pull the trigger.

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 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.

Brutes are merely brutal; men and women are capable of being devils and lunatics. They are no less capable of being fully human-even, occasionally, of being a bit more than fully human, of being saints, heroes and geniuses.

And why should man, added he, pretend to an exemption from the lot of all other animals? The whole earth, believe me, PHILO, is cursed and polluted. A perpetual war is kindled amongst all living creatures. Necessity, hunger, want, stimulate the strong and courageous: Fear, anxiety, terror, agitate the weak and infirm. The first entrance into life gives anguish to the new-born infant and to its wretched parent: Weakness, impotence, distress, attend each stage of that life: and it is at last finished in agony and horror.

As civilization advances, poetry almost necessarily declines.

It was the case of common soldiers deserting from their officers, to join a furious, licentious populace. It was a desertion to a cause, the real object of which was to level all those institutions, and to break all those connexions, natural and civil, that regulate and hold together the community by a chain of subordination; to raise soldiers against their officers; servants against their masters; tradesmen against their customers; artificers against their employers; tenants against their landlords; curates against their bishops; and children against their parents. That this cause of theirs was not an enemy to servitude, but to society.

Here the institution that compels is the state, the only purpose of which is to protect individuals from one another and the whole from external enemies. Some German philosophasters of this mercenary age would like to twist it into an institution for education and edification in morality; in the background of this lurks the Jesuitical purpose of eliminating personal freedom and the individual's personal development in order to make him into a mere cog in a Chinese machine of state and religion. But this is the path by which in the past one has arrived at the inquisitions, burning of heretics, and religious wars; Frederick the Great's pledge, 'In my country, each shall be able to tend to his salvation in his own fashion', indicated that he never wanted to tread that path.

Isn't history ultimately the result of our fear of boredom?

Sadism is plainly connected with the need for self-assertion. At the same time it cannot be separated from the idea of defeat. A sadist is a man, who, in some sense, has his back to the wall. Nothing is further from sadism, for example, than the cheerful, optimistic mentality of a Shaw or Wells.

Indeed, the drunken man while in that condition does not know the definition of drunkenness nor the scientific account of it; he has not the very least scientific knowledge of it. The sober man, on the other hand, knows the definition of drunkenness and its basis, yet he is not drunk in the very least. Again the doctor, when he is himself ill, knows the definition and causes of health and the remedies which restore it, and yet is lacking in health. Similarly there is a difference between knowing the true nature and causes and conditions of the ascetic life and actually leading such a life and forsaking the world.

They pass peaceful lives who ignore mine and thine.

The subconscious is ceaselessly murmuring, and it is by listening to these murmurs that one hears the truth.

Our lives are guided by that general conception of the course of things which has been created by society for social purposes. Our words, our phrases, our forms and processes and modes of thought, are common property, fashioned and perfected from age to age; an heirloom which every succeeding generation inherits as a precious deposit and a sacred trust to be handled on to the next one, not unchanged but enlarged and purified, with some clear marks of its proper handiwork. Into this, for good or ill, is woven every belief of every man who has speech of his fellows. An awful privilege, and an awful responsibility, that we should help to create the world in which posterity will live.

The ideal being? An angel ravaged by humor.

I've always been careful never to predict anything that had not already happened.

Where any answer is possible, all answers are meaningless.

For it is not death or pain that is to be feared, but the fear of pain or death.

I am not advocating a morality based on evolution. I am saying how things have evolved. I am not saying how we humans morally ought to behave.

If you look at the sociology of populism in the United States, it is tied most closely to population density, which... is correlated... to these types of cultural differences... to belief... in traditional cultural values, in family, in religion and the like, and conversely to... belief in immigration and diversity as strengths... This is the fundamental division that's taken hold of the United States. It has been augmented by technology because the internet has succeeded in... destroying every other source of authority that used to filter news and facts and information that... formed the basis of a democratic ability to have political discourse.

By the ruler's cultivation of his own character, the duties of universal obligation are set forth. By honoring men of virtue and talents, he is preserved from errors of judgment.

One need only open the eyes to see that the conquests of industry which have enriched so many practical men would never have seen the light, if these practical men alone had existed and if they had not been preceded by unselfish devotees who died poor, who never thought of utility, and yet had a guide far other than caprice.As Mach says, these devotees have spared their successors the trouble of thinking.

Time is a sort of river of passing events, and strong is its current; no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away.

To a person uninstructed in natural history, his country or sea-side stroll is a walk through a gallery filled with wonderful works of art, nine-tenths of which have their faces turned to the wall.

I say that man without the grace of God nonetheless remains the general omnipotence of God who effects, and moves and impels all things in a necessary, infallible course; but the effect of man's being carried along is nothing--that is, avails nothing in God's sight, nor is reckoned to be anything but sin.

Explore, and explore, and explore. Be neither chided nor flattered out of your position of perpetual inquiry. Neither dogmatise yourself, nor accept another's dogmatism. Why should you renounce your right to traverse the star-lit deserts of truth, for the premature comforts of an acre, house, and barn? Truth also has its roof, and bed, and board. Make yourself necessary to the world, and mankind will give you bread, and if not store of it, yet such as shall not take away your property in all men's possessions, in all men's affections, in art, in nature, and in hope.

I am neither a German citizen nor do I believe in anything that can be described as a "Jewish faith." But I am a Jew and glad to belong to the Jewish people, though I do not regard it in any way as chosen.

Nature magically suits the man to his fortunes, by making these the fruit of his character.
