The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.

Zeal to do all that is in one's power is, in truth, a proof of piety.

Philosophy resembles poetry in being an art for enforcing meditation, for driving the mind inwards until it sinks into its Object.

Be your money's master, not its slave.

The negative utilitarian might reply that this formulation of the problem is misleading. We do not live in a notional world where only a pinprick, minor pains, or even just "mild" suffering exists. In the real world, frightful horrors as well as humdrum malaise occur every day. The intensity of suffering is sometimes so dreadful that its victims are prepared to destroy themselves to bring their torment to an end. Each year, some 800,000 people across the planet kill themselves while in the grip of suicidal despair. Tens of millions of people are severely depressed or suffer chronic neuropathic pain. By way of contrast, the genteel conventions of an ethics seminar in academic philosophy, or the scholarly technicalities of a journal article, simply fail to come to terms with the enormity of what's at stake. To talk of a "pinprick" is to trivialise the NU ethical stance.

Let the states of equilibrium and harmony exist in perfection, and a happy order will prevail throughout heaven and earth, and all things will be nourished and flourish.

What cannot be imagined cannot even be talked about.

All media work us over completely. They are so pervasive in their personal, political, economic, aesthetic, psychological, moral, ethical, and social consequences that they leave no part of us untouched, unaffected, unaltered. The medium is the massage. Any understanding of social and cultural change is impossible without a knowledge of the way media work as environments. All media are extensions of some human faculty - psychic or physical.

A great man quotes bravely, and will not draw on his invention when his memory serves him with a word just as good.

Men sometimes submit to shame, to tyranny, to conquest, but they never long suffer anarchy. There is no people so barbarous that they escape this general law of humanity.

France has always more or less influenced manners in England; and when your fountain is choked up and polluted, the stream will not run long, or not run clear, with us, or perhaps with any nation. This gives all Europe, in my opinion, but too close and connected a concern in what is done in France. Excuse me, therefore, if I have dwelt too long on the atrocious spectacle of the 6th of October, 1789, or have given too much scope to the reflections which have arisen in my mind on occasion of the most important of all revolutions, which may be dated from that day, I mean a revolution in sentiments, manners, and moral opinions.

I like well your idea of issuing treasury notes bearing interest, because I am persuaded they would soon be withdrawn from circulation and locked up in vaults & private hoards. It would put it in the power of every man to lend his 100. or 1000 d. tho' not able to go forward on the great scale, and be the most advantageous way of obtaining a loan. The other idea of creating a National bank, I do not concur in, because it seems now decided that Congress has not that power, (altho' I sincerely wish they had it exclusively) and because I think there is already a vast redundancy, rather than a scarcity of paper medium.

It is of this sort of divine service I used the expression that, in comparison with the Christianity of the New Testament, it is playing Christianity. The expression is essentially true and characterizes the thing perfectly. For what does it mean to play, when one reflects how the word must be understood in this connection? It means to imitate, to counterfeit, a danger when there is no danger, and to do it in such a way that the more art is applied to it, the more delusive the pretense is that the danger is present.

He who does not prevent a crime, when he can, encourages it.

Religious persecution may shield itself under the guise of a mistaken and over-zealous piety.

Riemann has shewn that as there are different kinds of lines and surfaces, so there are different kinds of space of three dimensions; and that we can only find out by experience to which of these kinds the space in which we live belongs. In particular, the axioms of plane geometry are true within the limits of experiment on the surface of a sheet of paper, and yet we know that the sheet is really covered with a number of small ridges and furrows, upon which (the total curvature not being zero) these axioms are not true. Similarly, he says although the axioms of solid geometry are true within the limits of experiment for finite portions of our space, yet we have no reason to conclude that they are true for very small portions; and if any help can be got thereby for the explanation of physical phenomena, we may have reason to conclude that they are not true for very small portions of space.

The electronic age is a world in which causes and effects become almost interchangeable, as in music structures.

We cannot avoid conflict, conflict with society, other individuals and with oneself. Conflicts may be the sources of defeat, lost life and a limitation of our potentiality but they may also lead to greater depth of living and the birth of more far-reaching unities, which flourish in the tensions that engender them.

You should hammer your iron when it is glowing hot.

Transcendence constitutes selfhood.

It is because the method of physics does not satisfy the comprehension that we have to go on further.

Aesop's Fly, sitting on the axle of the chariot, has been much laughed at for exclaiming: What a dust I do raise!

Logic chases truth up the tree of grammar.

The human soul has need of disciplined participation in a common task of public value, and it has need of personal initiative within this participation. The human soul has need of security and also of risk. The fear of violence or of hunger or of any other extreme evil is a sickness of the soul. The boredom produced by a complete absence of risk is also a sickness of the soul.

When a series of progressive numbers is given as the result of observation, it may generally be reduced to law by combinations of arithmetical and geometrical progressions. A true formula for a progressive series of numbers cannot commonly be obtained from a narrow range of observations.

I believe in intuitions and inspirations. I sometimes feel that I am right. I do not know that I am. When two expeditions of scientists, financed by the Royal Academy, went forth to test my theory of relativity, I was convinced that their conclusions would tally with my hypothesis. I was not surprised when the eclipse of May 29, 1919, confirmed my intuitions. I would have been surprised if I had been wrong.

Cato the elder wondered how that city was preserved wherein a fish was sold for more than an ox.

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.

When it became obvious what a dumb and cruel and spiritually and financially and militarily ruinous mistake our war in Vietnam was, every artist worth a damn in this country, every serious writer, painter, stand-up comedian, musician, actor and actress, you name it, came out against the thing. We formed what might be described as a laser beam of protest, with everybody aimed in the same direction, focused and intense. This weapon proved to have the power of a banana-cream pie three feet in diameter when dropped from a stepladder five-feet high.

If man has learned to see and know what really is, he will act in accordance with truth, Epistemology is in itself ethics, and ethics is epistemology.

Sometimes I had an overwhelming urge to speak, not about that, but only to hint that there were some curious things about me which no one knew of. I wanted to find out whether other people had undergone similar experiences. I never succeeded in discovering so much as a trace of them in others. As a result, I had the feeling that I was either outlawed or elect, accursed or blessed.

We cannot stand by while the social contract is broken by those who chose conflict over equality. Those that want equal treatment for themselves have to treat others equally. They cannot lead with exclusion, then turn around and demand equal treatment. It is a double standard. If they are going to exclude first, then justice demands that we, the group that stands with universality, follow our duty to react and exclude those that exclude.

The created World is but a small Parenthesis in Eternity.

Further, it will not be amiss to distinguish the three kinds and, as it were, grades of ambition in mankind. The first is of those who desire to extend their own power in their native country, a vulgar and degenerate kind. The second is of those who labor to extend the power and dominion of their country among men. This certainly has more dignity, though not less covetousness. But if a man endeavor to establish and extend the power and dominion of the human race itself over the universe, his ambition (if ambition it can be called) is without doubt both a more wholesome and a more noble thing than the other two. Now the empire of man over things depends wholly on the arts and sciences. For we cannot command nature except by obeying her.

The three qualities of space and time reciprocally affect and qualify one another in experience. Space is inane save as occupied with active volumes. Pauses are holes when they do not accentuate masses and define figures as individuals. Extension sprawls and finally benumbs if it does not interact with place so as to assume intelligible distribution. Mass is nothing fixed. It contracts and expands, asserts and yields, according to its relations to other spatial and enduring things.... these are then the common properties of the matter of arts because there are general conditions without which an experience is not possible. As we saw earlier, the basic condition is felt relationship between doing and undergoing as the organism and environment interact.

Service of the people by sciences and arts will only exist when men live with the people and as the people live, and without presenting any claims will offer their scientific and artistic services, which the people will be free to accept or decline as they please.

Our patience will achieve more than our force.

Everything should be made simple as possible but no simpler.

Isolation is the worst possible counselor.

All living souls welcome whatsoever they are ready to cope with; all else they ignore, or pronounce to be monstrous and wrong, or deny to be possible.

Look now, this is the starting point of philosophy: the recognition that different people have conflicting opinions, the rejection of mere opinion so that it comes to be viewed with mistrust, an investigation of opinion to determine whether it is rightly held, and the discovery of a standard of judgement, comparable to the balance that we have devised for the determining of weights, or the carpenter's rule for determining whether things are straight or crooked.

Things are impressed better by active than by passive repetition. ...It pays better to wait and recollect by an effort from within, than to look at the book again.

All honour to those who can abnegate for themselves the personal enjoyment of life, when by such renunciation they contribute worthily to increase the amount of happiness in the world; but he who does it, or professes to do it, for any other purpose, is no more deserving of admiration than the ascetic mounted on his pillar. He may be an inspiriting proof of what men can do, but assuredly not an example of what they should.

Then what should we work for? Only this: proper understanding; unselfish action; truthful speech. A resolve to accept whatever happens as necessary and familiar, flowing like water from that same source and spring.

You do not ask what is the value, or what is the use, of this feeling. Of what use is the universe? What is the practical application of a million galaxies? Yet just because it has no use, it has a use-which may sound like a paradox, but is not. What, for instance, is the use of playing music? If you play to make money, to outdo some other artist, to be a person of culture, or to improve your mind, you are not really playing-for your mind is not on the music. You don't swing. When you come to think of it, playing or listening to music is a pure luxury, an addiction, a waste of valuable time and money for nothing more than making elaborate patterns of sound.

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.

They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head.
