But if judicious men skilled in Chymical affairs shall once agree to write clearly and plainly of them, and thereby keep men from being stunn'd... or imposed upon by dark and empty Words; 'tis to be hop'd that these men finding that they can no longer write impertinently and absurdly, without being laugh'd at for doing so, will be reduc'd either to write nothing, or Books that may teach us something, and not rob men, as formerly, of invaluable Time; and so ceasing to trouble the world with Riddles or Impertinencies, we shall either by their Books receive an Advantage, or by their silence escape an Inconvenience.

It is sweet and honorable to die for one's country.

I do not believe that sheer suffering teaches. If suffering alone taught, all the world would be wise, since everyone suffers. To suffering must be added mourning, understanding, patience, love, openness and the willingness to remain vulnerable. All these and other factors combined, if the circumstances are right, can teach and can lead to rebirth.

Once for all, then, a short precept is given thee: Love, and do what thou wilt: whether thou hold thy peace, through love hold thy peace; whether thou cry out, through love cry out; whether thou correct, through love correct; whether thou spare, through love do thou spare: let the root of love be within, of this root can nothing spring but what is good.

Life, individual or collective, personal or historic, is the one entity in the universe whose substance is compact of danger, of adventure. It is, in the strict sense of the word, drama. ... The primary, radical meaning of life appears when it is employed in the sense not of biology, but of biography. For the very strong reason that the whole of biology is quite definitely only a chapter in certain biographies, it is what biologists do in the portion of their lives open to biography.

The will of man has no power whatever over his opinions; he must, and ever did, and ever will, believe what has been, is, or may be impressed on his mind by his predecessors, and the circumstances which surround him.

It is mere illusion and pretty sentiment to expect much from mankind if he forgets how to make war. And yet no means are known which call so much into action as a great war, that rough energy born of the camp, that deep impersonality born of hatred, that conscience born of murder and cold-bloodedness, that fervor born of effort of the annihilation of the enemy, that proud indifference to loss, to one's own existence, to that of one's fellows, to that earthquake-like soul-shaking that a people needs when it is losing its vitality.

I will not be modest. Humble, as much as you like, but not modest. Modesty is the virtue of the lukewarm.

The Churches as Churches have always been and cannot fail to be institutions not only alien to, but directly hostile towards, Christ's teaching.

England, it is true, in causing a social revolution in Hindostan, was actuated only by the vilest interests, and was stupid in her manner of enforcing them. But that is not the question. The question is, can mankind fulfil its destiny without a fundamental revolution in the social state of Asia? If not, whatever may have been the crimes of England she was the unconscious tool of history in bringing about that revolution.

I have found a paper of mine among some others in which I call architecture 'petrified music.' Really there is something in this; the tone of mind produced by architecture approaches the effect of music.

No greater mistake can be made than to imagine that what has been written latest is always the more correct; that what is written later on is an improvement on what was written previously; and that every change means progress. Men who think and have correct judgment, and people who treat their subject earnestly, are all exceptions only. Vermin is the rule everywhere in the world: it is always at hand and busily engaged in trying to improve in its own way upon the mature deliberations of the thinkers.

Is any man afraid of change? Why what can take place without change?

Our trouble is that we have ignored and thus feel insecure in the enormous spectrum of love which lies between rather formal friendship and genital sexuality, and thus are always afraid that once we overstep the bounds of formal friendship we must slide inevitably to the extreme of sexual promiscuity.

Instead of defining the word, let us briefly characterize or describe the phenomenon. Ressentiment is a self-poisoning of the mind which has quite definite causes and consequences. It is a lasting mental attitude, caused by the systematic repression of certain emotions and affects which, as such, are normal components of human nature. Their repression leads to the constant tendency to indulge in certain kinds of value delusions and corresponding value judgments. The emotions and affects primarily concerned are revenge, hatred, malice, envy, the impulse to detract, and spite.

The man who hopes for naught at least has naught to fear.

In matters of style, swim with the current: in matters of principle, stand like a rock.

People with healthy self-esteem do not need to create pretend identities.

We are spinning our own fates, good or evil, and never to be undone. Every smallest stroke of virtue or of vice leaves its never so little scar. ...Nothing we ever do is, in strict scientific literalness, wiped out.

Not to display anger or other emotions. To be free of passion and yet full of love.

On condition that you protect my rights, I will protect your rights. How, then, does some party obtain the right to claim the protection of the other? Evidently, by actually protecting the rights of the other. But if this is so, no party will ever obtain a strictly legal claim to the protection of the other.

Religion is a subject on which I have ever been most scrupulously reserved. I have considered it as a matter between every man and his Maker in which no other, and far less the public, had a right to intermeddle.

So what is the alternative to traditional anthropocentric ethics? Antispeciesism is not the claim that "All Animals Are Equal", or that all species are of equal value, or that a human or a pig is equivalent to a mosquito. Rather the antispeciesist claims that, other things being equal, equally strong interests should count equally. Experiences that are subjectively negative or positive in hedonic tone to the same degree must count for the same.

Slavery is disheartening; but Nature is not so helpless but it can rid itself of every last wrong. But the spasms of nature are centuries and ages and will tax the faith of short-lived men. Slowly, slowly the Avenger comes, but comes surely. The proverbs of the nations affirm these delays, but affirm the arrival. They say, "God may consent, but not forever." The delay of the Divine Justice - this was the meaning and soul of the Greek Tragedy, - this was the soul of their religion.

The poor, stupid, free American citizen! Free to starve, free to tramp the highways of this great country, he enjoys universal suffrage, and, by that right, he has forged chains about his limbs. The reward that he receives is stringent labor laws prohibiting the right of boycott, of picketing, in fact, of everything, except the right to be robbed of the fruits of his labor.

The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. WORKING MEN OF ALL COUNTRIES, UNITE!

All this is merely saying that he, in a degree once common, but now very unusual, threw his feelings into his opinions; which truly it is difficult to understand how any one who possesses much of both, can fail to do. None but those who do not care about opinions, will confound it with intolerance. Those, who having opinions which they hold to be immensely important, and their contraries to be prodigiously hurtful, have any deep regard for the general good, will necessarily dislike, as a class and in the abstract, those who think wrong what they think right, and right what they think wrong: though they need not therefore be, nor was my father, insensible to good qualities in an opponent, nor governed in their estimation of individuals by one general presumption, instead of by the whole of their character.

Pascal is called the founder of modern probability theory. He earns this title not only for the familiar correspondence with Fermat on games of chance, but also for his conception of decision theory, and because he was an instrument in the demolition of probabilism, a doctrine which would have precluded rational probability theory.

No effective blueprint [of a political alternative to Empire] will ever arise from a theoretical articulation such as ours.

The soul active sees absolute truth; and utters truth, or creates.

I felt that human partitions - bodies, brains, and souls - were capable of being demolished, and that humanity might return again, after frightfully bloody wandering, to its primeval, divine oneness. In this condition, there is no such thing as "me", "you", and "he"; everything is a unity and this unity is a profound mystic intoxication in which death loses its scythe and ceases to exist. Separately, we die one by one, but all together we are immortal. Like prodigal sons, after so much hunger, thirst, and rebellion, we spread our arms and embrace our two parents: heaven and earth.

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.

The Austrian Germans and Magyars will be set free and wreak a bloody revenge on the Slav barbarians. The general war which will then break out will smash this Slav Sonderbund and wipe out all these petty hidebound nations, down to their very names. The next world war will result in the disappearance from the face of the earth not only of reactionary classes and dynasties, but also of entire reactionary peoples. And that, too, is a step forward.

Even the constantly reiterated insistence that we are miserable offenders, born in sin, is a kind of inverted arrogance: such vanity, to presume that our moral conduct has some sort of cosmic significance, as though the Creator of the Universe wouldn't have better things to do than tot up our black marks and our brownie points. The universe is all concerned with me. Is that not the arrogance that passeth all understanding? The Intellectual and Moral Courage of Atheism

We can come to look upon the deaths of our enemies with as much regret as we feel for those of our friends, namely, when we miss their existence as witnesses to our success.

The class of the wholly propertyless, who are obliged to sell their labor to the bourgeoisie in order to get, in exchange, the means of subsistence for their support. This is called the class of proletarians, or the proletariat.

Not one moment when I have not been conscious of being outside Paradise.

Most of what happens actually is forgotten.

We see that experience plays an indispensable role in the genesis of geometry; but it would be an error thence to conclude that geometry is, even in part, an experimental science. If it were experimental it would be only approximative and provisional. And what rough approximation!...The object of geometry is the study of a particular 'group'; but the general group concept pre-exists... in our minds. It is imposed on us, not as form of our sense, but as form of our understanding. Only, from among all the possible groups, that must be chosen... will be... the standard to which we shall refer natural phenomena.Experience guides us in this choice without forcing it upon us; it tells us not which is the truest geometry, but which is the most convenient.Notice that I have been able to describe the fantastic worlds... imagined without ceasing to employ the language of ordinary geometry.

On the whole, ought I not to rejoice that God was pleased to give me such a father; that from earliest years I had the example of a real man of God's own making continually before me? Let me learn of him. Let me write my books as he built his houses, and walk as blamelessly through this shadow world; if God so will, to rejoin him at last. Amen.

The greatness of America lies not in being more enlightened than any other nation, but rather in her ability to repair her faults.

The pursuit of knowledge is, I think, mainly actuated by love of power. And so are all advances in scientific technique. In politics, also, a reformer may have just as strong a love of power as a despot. It would be a complete mistake to decry love of power altogether as a motive. Whether you will be led by this motive to actions which are useful, or to actions which are pernicious, depends upon the social system, and upon your capacities.

Economics is on the side of humanity now.

Humanity may endure the loss of everything: all its possessions may be torn away without infringing its true dignity; - all but the possibility of improvement.

Even when there is no law, there is conscience.

A girl, if she has any pride, is so ashamed of having anything she wishes to say out of the hearing of her own family, she thinks it must be something so very wrong, that it is ten to one, if she have the opportunity of saying it, that she will not. And yet she is spending her life, perhaps, in dreaming of accidental means of unrestrained communion.

When reason rules, money is a blessing.

A man is as old as his arteries, and as young as his ideas.
