There is a plague on Man, the opinion that he knows something.

What is serious about excitement is that so many of its forms are destructive. It is destructive in those who cannot resist excess in alcohol or gambling. It is destructive when it takes the form of mob violence. And above all it is destructive when it leads to war. It is so deep a need that it will find harmful outlets of this kind unless innocent outlets are at hand. There are such innocent outlets at present in sport, and in politics so long as it is kept within constitutional bounds. But these are not sufficient, especially as the kind of politics that is most exciting is also the kind that does most harm. Civilized life has grown altogether too tame, and, if it is to be stable, it must provide harmless outlets for the impulses which our remote ancestors satisfied in hunting.

Warmth, warmth, more warmth! for we are dying of cold and not of darkness. It is not the night that kills, but the frost.

What I know at sixty, I knew as well at twenty. Forty years of a long, a superfluous, labor of verification.

One common strategy on which we should all be able to agree is to take steps to reduce the risk of human extinction when those steps are also highly effective in benefiting existing sentient beings. For example, eliminating or decreasing the consumption of animal products will benefit animals, reduce greenhouse gas emissions, and lessen the chances of a pandemic resulting from a virus evolving among the animals crowded into today's factory farms, which are an ideal breeding ground for viruses. That therefore looks like a high-priority strategy.

We now live in a technologically prepared environment that blankets the earth itself. The humanly contrived environment of electric information and power has begun to take precedence over the old environment of "nature." Nature, as it were, begins to be the content of our technology.

And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes.

Life cannot wait until the sciences may have explained the universe scientifically. We cannot put off living until we are ready. The most salient characteristic of life is its coerciveness: it is always urgent, "here and now" without any possible postponement. Life is fired at us point-blank. And culture, which is but its interpretation, cannot wait any more than can life itself.

It is because simplicity and vastness are both beautiful that we seek by preference simple facts and vast facts; that we take delight, now in following the giant courses of the stars, now in scrutinizing the microscope that prodigious smallness which is also a vastness, and now in seeking in geological ages the traces of a past that attracts us because of its remoteness.

For the things we have to learn before we can do, we learn by doing.

Stuart was not dismayed by his sexual feelings about the boy.

Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.

And now once again I asked myself the question: do I love her? And once more I could not answer, that is to say, again, for the hundredth time, I answered that I hated her.

When... in the course of all these thousands of years has man ever acted in accordance with his own interests?

The arrogance of age must submit to be taught by youth.

Again, Amyclas the Heracleotean, one of Plato's familiars, and Menæchmus, the disciple, indeed, of Eudoxus, but conversant with Plato, and his brother Dinostratus, rendered the whole of geometry as yet more perfect. But Theudius, the Magnian, appears to have excelled, as well in mathematical disciplines, as in the rest of philosophy. For he constructed elements egregiously, and rendered many particulars more universal. Besides, Cyzicinus the Athenian, flourished at the same period, and became illustrious in other mathematical disciplines, but especially in geometry. These, therefore, resorted by turns to the Academy, and employed themselves in proposing common questions.

The important thing isn't the soundness or otherwise of the argument, but for it to make you think.

The contradiction is this: man rejects the world as it is, without accepting the necessity of escaping it. In fact, men cling to the world and by far the majority do not want to abandon it.

Cicero said loud-bawling orators were driven by their weakness to noise, as lame men to take horse.

I am particularly grateful to Nozick for his unfailing help and encouragement during the last stages.

Supreme power rests in the will of all or of the majority.

We are as much as we see. Faith is sight and knowledge. The hands only serve the eyes.

Égalité is an expression of envy. It means, in the real heart of every Republican, " No one shall be better off than I am;" and while this is preferred to good government, good government is impossible.

John - I'm trying to find the Island in the West. Sensible - You refer, no doubt to some aesthetic experience.

One would have to be as unenlightened as an angel or an idiot to imagine that the human escapade could turn out well.

You', the ego, live in your left brain. When we say that man is the only creature who spends 99 per cent of his time inside his own head, we mean, in fact, inside his left cerebral hemisphere. And in the basement of the left hemisphere is the library full of filing cabinets -- the stuffy room that we mistake for reality.

If there is no immortality, there is no virtue. ... Without God and immortal life? All things are lawful then, they can do what they like?

There is only one way to avoid criticism: do nothing, say nothing and be nothing.

What interest, zest, or excitement can there be in achieving the right way, unless we are enabled to feel that the wrong way is also a possible and a natural way, - nay, more, a menacing and an imminent way? And what sense can there be in condemning ourselves for taking the wrong way, unless we need have done nothing of the sort, unless the right way was open to us as well? I cannot understand the willingness to act, no matter how we feel, without the belief that acts are really good and bad.

Each such answer to the great question, invariably asserted by the followers of its propounder, if not by himself, to be complete and final, remains in high authority and esteem, it may be for one century, or it may be for twenty: but, as invariably, Time proves each reply to have been a mere approximation to the truth-tolerable chiefly on account of the ignorance of those by whom it was accepted, and wholly intolerable when tested by the larger knowledge of their successors.

Ours is a problem in which deception has become organized and strong; where truth is poisoned at its source; one in which the skill of the shrewdest brains is devoted to misleading a bewildered people.

Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous.

I take it for granted, when I am invited to lecture anywhere, - for I have had a little experience in that business, - that there is a desire to hear what I think on some subject, though I may be the greatest fool in the country, - and not that I should say pleasant things merely, or such as the audience will assent to; and I resolve, accordingly, that I will give them a strong dose of myself. They have sent for me, and engaged to pay for me, and I am determined that they shall have me, though I bore them beyond all precedent.

I have endeavoured to show that no absolute structural line of demarcation, wider than that between the animals which immediately succeed us in the scale, can be drawn between the animal world and ourselves; and I may add the expression of my belief that the attempt to draw a physical distinction is equally futile, and that even the highest faculties of feeling and of intellect begin to germinate in lower forms of life.

Words are good servants but bad masters.

Physiology does not teach us how to digest, nor logic how to discourse, nor esthetics how to feel beauty or express it, nor ethics how to be good. And indeed it is well if they do not teach us how to be hypocrites; for pedantry, whether it be pedantry of logic, or of esthetics, or of ethics, is at bottom nothing but hypocrisy.

We know no spectacle so ridiculous as the British public in one of its periodical fits of morality.

Religion may be purified. This great work was begun two hundred years ago: but men can only bear light to come in upon them by degrees.

There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.

The members of Christ, many though they be, are bound to one another by the ties of charity and peace under the one Head, who is our Saviour Himself, and form one man. Often their voice is heard in the Psalms as the voice of one man; the cry of one is as the cry of all, for all are one in One.

Half our days we pass in the shadow of the earth; and the brother of death exacteth a third part of our lives.

Idleness is only fatal to the mediocre.

The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.

"Milton was right," said my Teacher. "The choice of every lost soul can be expressed in the words 'Better to reign in Hell than to serve in Heaven.' There is always something they insist on keeping even at the price of misery."

You called and cried out loud and shattered my deafness. You were radiant and resplendent, you put to flight my blindness. You were fragrant, and I drew in my breath and now pant after you. I tasted you, and I feel but hunger and thirst for you. You touched me, and I am set on fire to attain the peace which is yours.

Announced by all the trumpets of the sky Arrives the snow, and, driving o'er the fields, Seems nowhere to alight: the whited air Hides hills and woods, the river and the heaven, And veils the farm-house at the garden's end.

We have convictions only if we have studied nothing thoroughly.

Our claim is that a common political project is possible. This possibility of course will have to be verified and realized in practice. ... We are capable of democracy. The challange is to organize it politically.
