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.

All the excesses, all the violence, and all the vanity of great men, come from the fact that they know not what they are: it being difficult for those who regard themselves at heart as equal with all men... For this it is necessary for one to forget himself, and to believe that he has some real excellence above them, in which consists this illusion that I am endeavoring to discover to you.

If it is pleasing to observe in nature her desire to paint God in all his works, in which we see some traces of him because they are his images, how much more just is it to consider in the productions of minds the efforts which they make to imitate the essential truth, even in shunning it, and to remark wherein they attain it and wherein they wander from it, as I have endeavored to do in this study.

Those who deny the first principle should be flogged or burned until they admit that it is not the same thing to be burned and not burned, or whipped and not whipped.

The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant.

If you can speak what you will never hear, if you can write what you will never read, you have done rare things.

The fall of Empire, gentlemen, is a massive thing, however, and not easily fought. It is dictated by a rising bureaucracy, a receding initiative, a freezing of caste, a damming of curiosity, a hundred other factors. It has been going on, as I have said, for centuries, and it is too majestic and massive a movement to stop.

Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.

The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers. Luke 12:46 (KJV)

I am an investigator by inclination. I feel a great thirst for knowledge and an impatient eagerness to advance, also satisfaction at each progressive step. There was a time when I thought that all this could constitute the honor of humanity, and I despised the mob, which knows nothing about it. Rousseau set me straight. This dazzling excellence vanishes; I learn to honor men, and would consider myself much less useful than common laborers if I did not believe that this consideration could give all the others a value, to establish the rights of humanity.

Peace is more important than all justice; and peace was not made for the sake of justice, but justice for the sake of peace.

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!

But [your crime] will be there, one hundred times denied, always there, dragging itself behind you. Then you will finally know that you have committed your life with one throw of the die, once and for all, and there is nothing you can do but tug our crime along until your death. Such is the law, just and unjust, of repentance. Then we will see what will become of your young pride.

I am at heart more of a United-States-man than an Englishman.

There are ages in which the rational man and the intuitive man stand side by side, the one in fear of intuition, the other with scorn for abstraction. The latter is just as irrational as the former is inartistic. They both desire to rule over life: the former, by knowing how to meet his principle needs by means of foresight, prudence, and regularity; the latter, by disregarding these needs and, as an "overjoyed hero," counting as real only that life which has been disguised as illusion and beauty.

You can take better care of your secret than another can.

A prudent man should always follow in the path trodden by great men and imitate those who are most excellent.

What do I care about Jupiter? Justice is a human issue, and I do not need a god to teach it to me.

The man of perfect virtue is cautious and slow in his speech. When a man feels the difficulty of doing, can he be other than cautious and slow in speaking?

Apollo said that every one's true worship was that which he found in use in the place where he chanced to be.

A character is never the author who created him. It is quite likely, however, that an author may be all his characters simultaneously.

I disclose my mysteries to those who are worthy of my mysteries. (62)

The defiance of established authority, religious and secular, social and political, as a world-wide phenomenon may well one day be accounted the outstanding event of the last decade.

No punishment has ever possessed enough power of deterrence to prevent the commission of crimes. On the contrary, whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been.

Apart from autograph hunters, I get... many letters from Hindus, beseeching me to adopt some form of mysticism, from young Americans, asking me where I think the line should be drawn in petting, and from Poles, urging me to admit that while all other nationalism may be bad that of Poland is wholly noble. I get letters from engineers who cannot understand Einstein, and from parsons who think that I cannot understand Genesis, from husbands whose wives have deserted them - not (they say) that that would matter, but the wives have taken the furniture with them, and what in these circumstances should an enlightened male do? ...I get letters (concerning whose genuineness I am suspicious) trying to get me to advocate abortion, and I get letters from young mothers asking my opinion of bottle-feeding.

Hereby it is manifest, that during the time men live without a common Power to keep them all in awe, they are in that conditions called Warre; and such a warre, as is of every man, against every man.

Let great authors have their due, as time, which is the author of authors, be not deprived of his due, which is, further and further to discover truth.

In modern eyes, precious though wars may be they must not be waged solely for the sake of the ideal harvest. Only when forced upon one, is a war now thought permissible. It was not thus in ancient times. The earlier men were hunting men, and to hunt a neighboring tribe, kill the males, loot the village and possess the females, was the most profitable, as well as the most exciting, way of living. Thus were the more martial tribes selected, and in chiefs and peoples a pure pugnacity and love of glory came to mingle with the more fundamental appetite for plunder. Modern war is so expensive that we feel trade to be a better avenue to plunder; but modern man inherits all the innate pugnacity and all the love of glory of his ancestors. Showing war's irrationality and horror is of no effect on him. The horrors make the fascination. War is the strong life; it is life in extremis; war taxes are the only ones men never hesitate to pay, as the budgets of all nations show us.

For the philosophy which is so important in each of us is not a technical matter; it is our more or less dumb sense of what life honestly and deeply means. It is only partly got from books; it is our individual way of just seeing and feeling the total push and pressure of the cosmos. ...I have heard friends and colleagues try to popularize philosophy... but they soon grew dry, and then technical, and the results were only partially encouraging. So my enterprise is a bold one. The founder of pragmatism... gave... lectures... with that very word in its title,-flashes of brilliant light relieved against Cimmerian darkness! None of us... understood all that he said-yet here I stand making a very similar venture. ...There is... a curious fascination in hearing deep things talked about, even though neither we nor the disputants understand them. We get the problematic thrill, we feel the presence of the vastness.

We ought neither to fasten our ship to one small anchor nor our life to a single hope.

To those whose talents are above mediocrity, the highest subjects may be announced. To those who are below mediocrity, the highest subjects may not be announced.

When a man acts in ways that annoy us we wish to think him wicked, and we refuse to face the fact that his annoying behaviour is a result of antecedent causes which, if you follow them long enough, will take you beyond the moment of his birth and therefore to events for which he cannot be held responsible by any stretch of imagination.

It seldom happens, however, that a great proprietor is a great improver.

The blazing evidence of immortality is our dissatisfaction with any other solution.

I saw men go up and down, In the country and the town, With this tablet on their neck,- 'Judgement and a judge we seek.' Not to monarchs they repair, Nor to learned jurist's chair; But they hurry to their peers, To their kinsfolk and their dears; Louder than with speech they pray,- 'What am I? companion, say.'

Is Wagner a human being at all? Is he not rather a disease? He contaminates everything he touches - he has made music sick.

It is not meet to take the children's bread, and to cast it to dogs. 15:26 (KJV)

If, when a man writes a poem or commits a murder, the bodily movements involved in his act result solely from physical causes, it would seem absurd to put up a statue to him in the one case and to hang him in the other.

So clearly will truths kindle light for truths.

M. Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind, and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry.

The universe is what it is, not what I choose that it should be.

It is not your strength and your natural power that subjects all these people to you. Do not pretend then to rule them by force or to treat them with harshness. Satisfy their reasonable desires; alleviate their necessities; let your pleasure consist in being beneficent; advance them as much as you can, and you will act like the true king of desire.

See that no man know it. 9:30 (KJV) Said to the two blind men.

An individual may perceive a way of life, or a method of social organisation, by which more of the desires of mankind could be satisfied than under the existing method. If he perceives truly, and can persuade men to adopt his reform, he is justified. Without rebellion, mankind would stagnate, and injustice would be irremediable.

So long as antimilitarists propose no substitute for war's disciplinary function, no moral equivalent of war, analogous, as one might say, to the mechanical equivalent of heat, so long they fail to realize the full inwardness of the situation.

Titles are an important part of a story and I take considerable care in choosing one. In fact, I cannot start a story until I have chosen a title.

People who originally have no means but are ultimately able to earn a great deal, through whatever talents they may possess, almost always come to think that these are permanent capital and that what they gain through them is interest. Accordingly, they do not put aside part of their earnings to form a permanent capital, but spend their money as fast as they earn it. But they are then often reduced to poverty because their earnings decrease or come to an end after their talent, which was of a transitory nature, is exhausted, as happens, for example, in the case of almost all the fine arts; or because it could be brought to bear only under a particular set of circumstances that has ceased to exist.

The reservedness and distance that fathers keep, often deprive their sons of that refuge which would be of more advantage to them than an hundred rebukes or chidings.

This art, which I call the art of persuading, and which, properly speaking, is simply the process of perfect methodical proofs, consists of three essential parts: of defining the terms of which we should avail ourselves by clear definitions, of proposing principles of evident axioms to prove the thing in question; and of always mentally substituting in the demonstrations the definition in the place of the thing defined.

Man flows at once to God when the channel of purity is open.
