Thus our duties to animals are indirectly duties to humanity.

To be sure, risks abound; but no one is proposing compassionate stewardship of ecosystems by philosophers. Humans are capable of choosing our own future pain-sensitivity too; but any species-wide genomic shift in human pain tolerance will depend on the willingness of prospective parents to use preimplantation genetic screening.

We were laboring under a dropsical fulness of circulating medium. Nearly all of it is now called in by the banks, who have the regulation of the safety-valves of our fortunes, and who condense and explode them at their will. Lands in this State cannot now be sold for a year's rent; and unless our Legislature have wisdom enough to effect a remedy by a gradual diminution only of the medium, there will be a general revolution of property in this state.

Science is not a system of certain, or well established, statements; nor is it a statement which steadily advances towards state of finality. Our science is not knowledge (epistēmē): it can newer claim to have attained truth, or even substitute for it, such as probability. . . . We do not know; we can only guess.

Epicurus, the great teacher of happiness, has correctly and finely divided human needs into three classes. First there are the natural and necessary needs which, if they are not satisfied, cause pain. Consequently, they are only victus et amictus [food and clothing] and are easy to satisfy. Then we have those that are natural yet not necessary, that is, the needs for sexual satisfaction. ... These needs are more difficult to satisfy. Finally, there are those that are neither natural nor necessary, the needs for luxury, extravagance, pomp, and splendour, which are without end and very difficult to satisfy.

The world is divided into men who have wit and no religion and men who have religion and no wit.

The application of algebra to geometry... far more than any of his metaphysical speculations, has immortalized the name of Descartes, and constitutes the greatest single step ever made in the progress of the exact sciences.

Mathematical Analysis is... the true rational basis of the whole system of our positive knowledge.

Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end, an end which it was already but too easy to arrive at.

Justice is a temporary thing that must at last come to an end; but the conscience is eternal and will never die.

A Muslim who knows French will never be a dangerous Muslim.

In a sense, people are our proper occupation. Our job is to do them good and put up with them. But when they obstruct our proper tasks, they become irrelevant to us--like sun, wind, and animals. Our actions may be impeded by them, but there can be no impeding our intentions or our dispositions. Because we can accommodate and adapt. The mind adapts and converts to its own purposes the obstacle to our acting. The impediment to action advances action. What stands in the way becomes the way.

I do not mean to be disrespectful, but the attempt of the Lords to stop the progress of reform reminds me very forcibly of the great storm at Sidmouth, and of the conduct of the excellent Mrs Partington on that occasion. In the winter of 1824 there set in a great flood upon that town - the tide rose to an incredible height - the waves rushed in upon the houses, and everything was threatened with destruction. In the midst of this sublime and terrible storm, Dame Partington, who lived upon the beach, was seen at the door of her house with mop and pattens, trundling her mop, squeezing out the sea-water, and vigorously pushing away the Atlantic Ocean. The Atlantic was roused; Mrs. Partington's spirit was up. But I need not tell you that the contest was unequal.

Conversation is an art in which a man has all mankind for his competitors, for it is that which all are practising every day while they live.

Peace be with you. Receive my peace unto yourselves. Beware that no one lead you astray saying Lo here or lo there! For the Son of Man is within you. Follow after Him! Those who seek Him will find Him. Go then and preach the gospel of the Kingdom. Do not lay down any rules beyond what I appointed you, and do not give a law like the lawgiver lest you be constrained by it.

The culture of a civilization is the art and literature through which it rises to consciousness of itself and defines its vision of the world.

Poetry must be new as foam, and as old as the rock.

To believe in a God means to understand the question about the meaning of life. To believe in a God means to see that the facts of the world are not the end of the matter. To believe in God means to see that life has a meaning.

There is probably no more abused a term in the history of philosophy than "representation," and my use of this term differs both from its use in traditional philosophy and from its use in contemporary cognitive psychology and artificial intelligence.... The sense of "representation" in question is meant to be entirely exhausted by the analogy with speech acts: the sense of "represent" in which a belief represents its conditions of satisfaction is the same sense in which a statement represents its conditions of satisfaction. To say that a belief is a representation is simply to say that it has a propositional content and a psychological mode.

Did you ever hear my definition of marriage? It is, that it resembles a pair of shears, so joined that they can not be separated; often moving in opposite directions, yet always punishing anyone who comes between them.

As an eminent pioneer in the realm of high frequency currents... I congratulate you on the great successes of your life's work.

I sincerely rejoice at the acceptance of our new Constitution by nine States. It is a good canvas, on which some strokes only want retouching. What these are, I think are sufficiently manifested by the general voice from north to south, which calls for a bill of rights.

Someone who knows too much finds it hard not to lie.

Men go to a fire for entertainment. When I see how eagerly men will run to a fire, whether in warm or in cold weather, by day or by night, dragging an engine at their heels, I'm astonished to perceive how good a purpose the level of excitement is made to serve.

I claim credit for nothing. Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect as well as for the star. Human beings, vegetables or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible player.

Fortune has taken away, but Fortune has given.

Praise be to God with all due praise, and a prayer for Muhammad His chosen servant and apostle. The purpose of this treatise is to examine, from the standpoint of the study of the Law, whether the study of philosophy and logic is allowed by the Law, or prohibited, or commanded either by way of recommendation or as obligatory.

The same feeling of not belonging, of futility, wherever I go: I pretend interest in what matters nothing to me, I bestir myself mechanically or out of charity, without ever being caught up, without ever being somewhere. What attracts me is elsewhere, and I don't know where that elsewhere is.

The key to understanding Crowley is the same as the key to understanding the Marquis de Sade. Both wasted an immense amount of energy screaming defiance at the authority they resented so much, and lacked the insight to see that they were shaking their fists at an abstraction.

Liberty, as we all know, cannot flourish in a country that is permanently on a war footing, or even a near war footing. Permanent crisis justifies permanent control of everybody and everything by the agencies of central government.

It is a mistake to suppose that the whole issue is how to free man. The issue is to improve the way in which he is controlled.

I am a perfect stranger to France, which I have never seen, and I expect nothing from her king, whom I shall never know.

Do not even think of doing what ought not to be done.

False men and shams talk big and do nothing.

The way for a person to develop a [writing] style is (a) to know exactly what he wants to say, and (b) to be sure he is saying exactly that. The reader, we must remember, does not start by knowing what we mean. If our words are ambiguous, our meaning will escape him. I sometimes think that writing is like driving sheep down a road. If there is any gate open to the left or the right the readers will most certainly go into it.

Crocodiles sweetly shut their lidded eyes, and yawned,for the blond meat had been quite good, and in slow rainsnew flesh would sprout once more and then be munched anew.

Reason can make little headway on its own and struggles to be heard; often it has to be - so to speak - armed by the fearsome epigram. French wit pricks like a needle, so that the thread goes through the hole.

The sea does not reward those who are too anxious, too greedy, or too impatient. To dig for treasures shows not only impatience and greed, but lack of faith. Patience, patience, patience, is what the sea teaches. Patience and faith. One should lie empty, open, choiceless as a beach - waiting for a gift from the sea.

It is hard to have patience with people who say 'There is no death' or 'Death doesn't matter.' There is death. And whatever is matters. And whatever happens has consequences, and it and they are irrevocable and irreversible. You might as well say that birth doesn't matter.

Two elements must therefore be rooted out once for all-the fear of future suffering, and the recollection of past suffering; since the latter no longer concerns me, and the former concerns me not yet.

It is not truth that makes man great, but man that makes truth great.

Children are all foreigners.

Marriage is for women the commonest mode of livelihood, and the total amount of undesired sex endured by women is probably greater in marriage than in prostitution.

They say cowardice is infectious; but then argument is, on the other hand, a great emboldener.

I find that even Eminent Writers (such as Raymund Lully, Paracelsus, and others) do so abuse the termes they employ, that as they will now and then give divers things one name, so they will oftentimes give one thing, many Names; and some of them (perhaps) such, as do much more properly signifie some Distinct Body of another kind; nay even in Technical Words or Termes of Art, they refrain not from this Confounding Liberty; but will, as I have Observ'd call the same Substance, sometimes the Sulphur, and Sometimes the Mercury, of a Body.

Nothing is more important than the formation of fictional concepts, which teach us at last to understand our own.

Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.
