I consider one of the most important duties of any scientist the teaching of science to students and to the general public.

The truth remains that, after adolescence has begun, "words, words, words," must constitute a large part, and an always larger part as life advances, of what the human being has to learn.

Instead of deciding once in three or six years which member of the ruling class was to misrepresent the people in Parliament, universal suffrage was to serve the people, constituted in Communes, as individual suffrage serves every other employer in the search for the workmen and managers in his business.

Indeed, if we consider the unblushing promises of reward and the staggering nature of the rewards promised in the Gospels, it would seem that Our Lord finds our desires, not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.

Behold, there was a man named Zacchaeus, which was the chief among the publicans, and he was rich. And he sought to see Jesus who he was; and could not for the press, because he was little of stature. And he ran before, and climbed up into a sycomore tree to see him: for he was to pass that way. And when Jesus came to the place, he looked up, and saw him, and said unto him, Zacchaeus, make haste, and come down; for to day I must abide at thy house. And he made haste, and came down, and received him joyfully. And when they saw it, they all murmured, saying, That he was gone to be guest with a man that is a sinner. And Zacchaeus stood, and said unto the Lord: Behold, Lord, the half of my goods I give to the poor; and if I have taken any thing from any man by false accusation, I restore him fourfold. And Jesus said unto him, This day is salvation come to this house, forsomuch as he also is a son of Abraham. For the Son of man is come to seek and to save that which was lost. 19:2-10

People are entirely too disbelieving of coincidence. They are far too ready to dismiss it and to build arcane structures of extremely rickety substance in order to avoid it. I, on the other hand, see coincidence everywhere as an inevitable consequence of the laws of probability, according to which having no unusual coincidence is far more unusual than any coincidence could possibly be.

There is nothing more visible than what is secret, and nothing more manifest than what is minute. Therefore the superior man is watchful over himself, when he is alone.

The Path is not far from man. When men try to pursue a course, which is far from the common indications of consciousness, this course cannot be considered The Path.

Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.

The souls of emperors and cobblers are cast in the same mold...The same reason that makes us wrangle with a neighbor creates a war betwixt princes.

Oh. Marx's love for Shakespeare! It is well known. Chris Hani shared the same passion. I have just learned this and I like the idea. Even though Marx more often quotes Timon of Athens, the Manifesto seems to evoke or convoke, right from the start, the first coming of the silent ghost, the apparition of the spirit that does not answer, on those ramparts of Elsinore which is then the old Europe.

In the vaunted works of Art The master stroke is Nature's part.

The entire lower world was created in the likeness of the higher world. All that exists in the higher world appears like an image in this lower world; yet all this is but One.

He who dares not offend cannot be honest. "The Forester's Letters", Letter III: To Cato, Pennsylvania Journal

There is no author to whom my father thought himself more indebted for his own mental culture, than Plato, or whom he more frequently recommended to young student. I can bear similar testimony in regard to myself. The Socratic method, of which the Platonic dialogues are the chief example, is unsurpassed as a discipline for correcting the errors, and clearing up the confusions incident to the intellectus sibi permissus...

Freedom is what you do with what's been done to you.

Many of the actions by which men have become rich are far more harmful to the community than the obscure crimes of poor men, yet they go unpunished because they do not interfere with the existing order.

Whenever the general disposition of the people is such, that each individual regards those only of his interests which are selfish, and does not dwell on, or concern himself for, his share of the general interest, in such a state of things, good government is impossible.

The man described for us, whom we are invited to free, is already in himself the effect of a subjection much more profound than himself. A 'soul' inhabits him and brings him to existence...the soul is the effect and instrument of political anatomy; the soul is the prison of the body.

Proverbs are always platitudes until you have personally experienced the truth of them.

Be not swept off your feet by the vividness of the impression, but say, "Impression, wait for me a little. Let me see what you are and what you represent. Let me try you."

What a pity and what a poverty of spirit, to assert that beasts are machines deprived of knowledge and sentiment, which affect all their operations in the same manner, which learn nothing, never improve, &c. [...] Some barbarians seize this dog, who so prodigiously excels man in friendship, they nail him to a table, and dissect him living, to show the mezarian veins. You discover in him all the same organs of sentiment which are in yourself. Answer me, machinist, has nature arranged all the springs of sentiment in this animal that he should not feel? Has he nerves to be incapable of suffering? Do not suppose this impertinent contradiction in nature. [...] The animal has received those of sentiment, memory, and a certain number of ideas. Who has bestowed these gifts, who has given these faculties? He who has made the herb of the field to grow, and who makes the earth gravitate towards the sun.

The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question.

I have cast fire upon the world, and see, I am guarding it until it blazes. (10)

Saying is one thing and doing is another.

Nothing can be produced from nothing.

I... believe in the rationalist tradition of a commonwealth of learning, and in the urgent need to preserve this tradition.

The middle sort of historians (of which the most part are) spoil all; they will chew our meat for us.

Pacifists ought to enter more deeply into the aesthetical and ethical point of view of their opponents. ... 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. And as a rule they do fail. The duties, penalties, and sanctions pictured in the utopias they paint are all too weak and tame to touch the military-minded.

For creation is not a change, but that dependence of the created existence on the principle from which it is instituted, and thus is of the genus of relation; whence nothing prohibits it being in the created as in the subject. Creation is thus said to be a kind of change, according to the way of understanding, insofar as our intellect accepts one and the same thing as not existing before and afterwards existing.

For man seeketh in society comfort, use, and protection: and they be three wisdoms of divers natures, which do often sever: wisdom of the behaviour, wisdom of business, and wisdom of state.

Nobody knows what is going to happen because so much depends on an enormous number of variables, on simple hazard. On the other hand if you look at history retrospectively, then, even though it was contingent, you can tell a story that makes sense.... Jewish history, for example, in fact had its ups and downs, its, enmities and its friendships, as every history of all people has. The notion that there is one unilinear history is of course false. But if you look at it after the experience of Auschwitz it looks as though all of history-or at least history since the Middle Ages - had no other aim than Auschwitz.... This, is the real problem of every philosophy of history how is it possible that in retrospect it always looks as though it couldn't have happened otherwise?

The commodity is first of all, an external object, a thing which through its qualities satisfies human needs of whatever kind. The nature of these needs, whether they arise, for example, from the stomach, or the imagination, makes no difference. Nor does it matter here how the thing satisfies man's need, whether directly as a means of subsistence, i.e. an object of consumption, or indirectly as a means of production.

Practice yourself, for heaven's sake, in little things; and thence proceed to greater.

The man of principles has character. Of him we know definitely what to expect. He does not act on the basis of his instinct, but on the basis of his will. Therefore, without being redundant one can classify characteristics according to a person's faculty of desire (what is practical), as a) his nature, or natural talent, b) his temperament, or disposition, and c) his general character, or mode of thinking.

It would be too ridiculous to go about seriously to prove that wealth does not consist in money, or in gold and silver; but in what money purchases, and is valuable only for purchasing. Money no doubt, makes always a part of the national capital; but it has already been shown that it generally makes but a small part, and always the most unprofitable part of it.

Take a book, the poorest one written, but read it with the passion that it is the only book you will read-ultimately you will read everything out of it, that is, as much as there was in yourself, and you could never get more out of reading, even if you read the best of books.

Seek first God's Kingdom, that is, become like the lilies and the birds, become perfectly silent - then shall the rest be added unto you.

Grief and disappointment give rise to anger, anger to envy, envy to malice, and malice to grief again, till the whole circle be completed.

Philosophical problems can be compared to locks on safes, which can be opened by dialing a certain word or number, so that no force can open the door until just this word has been hit upon, and once it is hit upon any child can open it.

The believers in the non-natural character of sudden conversion have had practically to admit that there is no unmistakable class-mark distinctive of all true converts. The super-normal incidents, such as voices and visions and overpowering impressions of the meaning of suddenly presented scripture texts, the melting emotions and tumultuous affections connected with the crisis of change, may all come by way of nature, or worse still, be counterfeited by Satan. The real witness of the spirit to the second birth is to be found only in the disposition of the genuine child of God, the permanently patient heart, the love of self eradicated. And this, it has to be admitted, is also found in those who pass no crisis, and may even be found outside of Christianity altogether.

So it is with minds. Unless you keep them busy with some definite subject that will bridle and control them, they throw themselves in disorder hither and yon in the vague field of imagination. ..And there is no mad or idle fancy that they do no bring forth in the agitation.

The rules of logic are to mathematics what those of structure are to architecture.

In Mohammedanism the narrow principle of the Jews is expanded into universality and thereby overcome. Here, God is no longer, as in the Far East, regarded as existent in an immediately sensory way but is conceived as the one infinite power elevated above all the multiplicity of the world. Mohammedanism is, therefore, in the strictest sense of the word, the religion of sublimity.

I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true.

If you only notice human proceedings, you may observe that all who attain great power and riches, make use of either force or fraud; and what they have acquired either by deceit or violence, in order to conceal the disgraceful methods of attainment, they endeavor to sanctify with the false title of honest gains. Those who either from imprudence or want of sagacity avoid doing so, are always overwhelmed with servitude and poverty; for faithful servants are always servants, and honest men are always poor; nor do any ever escape from servitude but the bold and faithless, or from poverty, but the rapacious and fraudulent. God and nature have thrown all human fortunes into the midst of mankind; and they are thus attainable rather by rapine than by industry, by wicked actions rather than by good. Hence it is that men feed upon each other, and those who cannot defend themselves must be worried.

Plato... introduces two infinities, because both in increase and diminution there appears to be transcendency, and a progression to infinity. Though... he did not use them: for neither is there infinity in numbers by diminution or division; since unity is a minimum: nor by increase; for he extends number as far as to the decad.

Whenever the legislature attempts to regulate the differences between masters and their workmen, its counsellors are always the masters. When the regulation, therefore, is in favor of the workmen, it is always just and equitable; but it is sometimes otherwise when in favor of the masters.

The doctrine of the Second Coming has failed, so far as we are concerned, if it does not make us realize that at every moment of every year in our lives Donne's question "What if this present were the world's last night?" is equally relevant.
