The saying that a little knowledge is a dangerous thing is, to my mind, a very dangerous adage. If knowledge is real and genuine, I do not believe that it is other than a very valuable possession, however infinitesimal its quantity may be. Indeed, if a little knowledge is dangerous, where is the man who has so much as to be out of danger?

Rational mechanics must be the science of the motions which result from any forces, and of the forces which are required for any motions, accurately propounded and demonstrated. For many things induce me to suspect, that all natural phenomena may depend upon some forces by which the particles of bodies are either drawn towards each other, and cohere, or repel and recede from each other: and these forces being hitherto unknown, philosophers have pursued their researches in vain. And I hope that the principles expounded in this work will afford some light, either to this mode of philosophizing, or to some mode which is more true.

One must look into hell before one has any right to speak of heaven.

The struggle between the opponents and defenders of capitalism is a struggle between innovators who do not know what innovation to make and conservatives who do not know what to conserve.

The great writers to whom the world owes what religious liberty it possesses, have mostly asserted freedom of conscience as an indefeasible right, and denied absolutely that a human being is accountable to others for his religious belief.

My sympathies are, of course, with the Government side, especially the Anarchists; for Anarchism seems to me more likely to lead to desirable social change than highly centralized, dictatorial Communism.

This idea of weapons of mass extermination is utterly horrible and is something which no one with one spark of humanity can tolerate. I will not pretend to obey a government which is organising a mass massacre of mankind.

I regard you with an indifference closely bordering on aversion.

The eye of the intellect "sees in all objects what it brought with it the means of seeing."

Concepts, like individuals, have their histories, and are just as incapable of withstanding the ravages of time as are individuals.

The ideology of development has implied the globalization of the priorities, patterns, and prejudices of the West. Instead of self-generated, development is imposed. Instead of coming from within, it is externally guided. Instead of contributing to the maintenance of diversity, development has created homogeneity...

I don't understand why we must do things in this world, why we must have friends and aspirations, hopes and dreams. Wouldn't it be better to retreat to a faraway corner of the world, where all its noise and complications would be heard no more? Then we could renounce culture and ambitions; we would lose everything and gain nothing; for what is there to be gained from this world?

Useless laws weaken the necessary laws.

I think of the course of human history as a long, swelling, increasingly polyphonic poem - a poem that leads up to nothing save itself. When the species is extinct, "human nature's total message" will not be a set of propositions, but a set of vocabularies - the more, and the more various, the better.

Necessity may be defined in two ways, conformably to the two definitions of cause, of which it makes an essential part. It consists either in the constant conjunction of like objects, or in the inference of the understating from one object to another.

In contrast to festivals, events do not create community.

Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice.

Freedom can be manifested only in the void of beliefs, in the absence of axioms, and only where the laws have no more authority than a hypothesis.

Love may forgive all infirmities and love still in spite of them: but Love cannot cease to will their removal.

Among the smaller duties of life I hardly know any one more important than that of not praising where praise is not due.

A proud man is always looking down on things and people: and, of course, as long as you are looking down, you cannot see something that is above you.

Influences of various kinds conspire to increase corporate action and decrease individual action. And the change is being on all sides aided by schemers, each of whom thinks only of his pet plan and not at all of the general reorganization which his plan, joined with others such, are working out. It is said that the French Revolution devoured its own children. Here, an analogous catastrophe seems not unlikely. The numerous socialistic changes made by Act of Parliament, joined with the numerous others presently to be made, will by-and-by be all merged in State-socialism-swallowed in the vast wave which they have little by little raised."But why is this change described as 'the coming slavery'?," is a question which many will still ask. The reply is simple. All socialism involves slavery.

Facing a landscape annihilated by the light, to remain serene supposes a temper I do not have. The sun is my purveyor of black thoughts; and summer the season when I have always reconsidered my relations with this world and with myself, to the greatest prejudice of both.

I am showing my pupils details of an immense landscape which they cannot possibly know their way around.

The reward in heaven is the perpetual bait, a bait that has caught man in an iron net, a strait-jacket which does not let him expand or grow. All pioneers of truth have been, and still are, reviled; they have been, and still are, persecuted. But did they ask humanity to pay the price? Did they seek to bribe mankind to accept their ideas? They knew too well that he who accepts a truth because of the bribe, will soon barter it away to a higher bidder...Proud and self-reliant characters prefer hatred to such sickening artificial love. Not because of any reward does a free spirit take his stand for a great truth, nor has such a one ever been deterred because of fear of punishment.

In organized groups such as the army or the Church there is either no mention of love whatsoever between the members, or it is expressed only in a sublimated and indirect way, through the mediation of some religious imagine in the love of whom the members unite and whose all-embracing love they are supposed to imitate in their attitude towards each other. ... It is one of the basic tenets of fascist leadership to keep primary libidinal energy on an unconscious level so as to divert its manifestations in a way suitable to political ends.

Rohde became more and more firmly bound to the bourgeois world, its institutions and accepted opinions. ... The contrast between the two natures makes Rohde and Nietzsche exemplary representatives of two distinctive worlds. In their youth they both live in the realm of boundless possibilities and feel an affinity through the exuberance of their noble aspirations. Subsequently they go in opposite directions. Nietzsche remains young, leaving concrete reality as his task assumes existential import. Rohde grows old, bourgeois, stable, and skeptical. Hence courage is a fundamental trait in Nietzsche, plaintive self-irony in Rohde. ... Rohde retained the interests but not the attitudes of his youth; he looked to the world of the Greeks for the object of his contemplation rather than the norm of obligation.

It is the slowest pulsation which is the most vital. The hero will then know how to wait, as well as to make haste. All good abides with him who waiteth wisely.

Holy Christendom has, in my judgment, no better teacher after the apostles than St. Augustine.

I see your vile implication. My only explanation for it is that you are criminally insane.

Government was intended to suppress injustice, but its effect has been to embody and perpetuate it.

Anger is a momentary madness so control your passion or it will control you.

Did you ever hear my definition of marriage? It is, that it resembles a pair of shears, so joined that they can not be separated; often moving in opposite directions, yet always punishing anyone who comes between them.

We have seen that the true source of the power of demagogues is the obstinacy of rulers and that a liberal Government makes a conservative people. 

Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.

The wise and virtuous man is at all times willing that his own private interests should be sacrificed to the public interest of his own particular society--that the interests of this order of society be sacrificed to the greater interest of the state. He should therefore he equally willing that all those inferior interests should be sacrificed to the greater society of all sensible and intelligent beings.

If Governments neglect to invite what noble intellect there is, then too surely all intellect, not omnipotent to resist bad influences, will tend to become beaverish ignoble intellect; and quitting high aims, which seem shut up from it, will help itself forward in the way of making money and such like; or will even sink to be sham intellect, helping itself by methods which are not only beaverish but vulpine, and so "ignoble" as not to have common honesty.

Men and boys are learning all kinds of trades but how to make men of themselves. They learn to make houses; but they are not so well housed, they are not so contented in their houses, as the woodchucks in their holes. What is the use of a house if you haven't got a tolerable planet to put it on? - If you cannot tolerate the planet that it is on? Grade the ground first. If a man believes and expects great things of himself, it makes no odds where you put him, or what you show him ... he will be surrounded by grandeur. He is in the condition of a healthy and hungry man, who says to himself, - How sweet this crust is!

In erotic love, two people who were separate become one. In motherly love, two people who were one become separate. The mother must not only tolerate, she must wish and support the child's separation.

Wind indeed increases fire, but custom love.

I could see clearly that this problem could only be solved on the individual and personal level; political revolt is irrelevant. Both Camus and Sartre had been neatly hog-tied by their earlier radicalism. Camus came to see that rebellion is a political roundabout that revolves back to the same old tyranny; too ashamed to admit that he had outgrown his leftism, he found himself in an intellectual cul-de-sac. Sartre accused Camus of being a reactionary; but he paid for his own refusal to reexamine his political convictions by congealing into a grotesque attitude of permanent indignation, shaking his fist at some abstract Authority. Where politics is concerned, he seemed determined to be guided by his emotions.

There is something which unites magic and applied science while separating both from the wisdom of earlier ages. For the wise men of old the cardinal problem had been how to conform the soul to reality, and the solution had been knowledge, self-discipline, and virtue. For magic and applied science alike the problem is how to subdue reality to the wishes of men.

Don't you know that a good and excellent person does nothing for the sake of appearances, but only for the sake of having acted right?

Whatever moral rules you have deliberately proposed to yourself abide by them as they were laws, and as if you would be guilty of impiety by violating any of them. Don't regard what anyone says of you, for this, after all, is no concern of yours. How long, then, will you put off thinking yourself worthy of the highest improvements and follow the distinctions of reason? You have received the philosophical theorems, with which you ought to be familiar, and you have been familiar with them. What other master, then, do you wait for, to throw upon that the delay of reforming yourself?... Let whatever appears to be the best be to you an inviolable law.

So in all human affairs one notices, if one examines them closely, that it is impossible to remove one inconvenience without another emerging.

Losing love is so rich a philosophical ordeal that it makes a hairdresser into a rival of Socrates.

The unbeliever walks for a quadrillion miles, yet one moments of reality makes up for it.
