The diversity of physical arguments and opinions embraces all sorts of methods.

There is no general reason to expect evolution to be progressive - even in the weak, value-neutral sense. There will be times when increased size of some organ is favoured and other times when decreased size is favoured. Most of the time, average-sized individuals will be favoured in the population and both extremes will be penalised. During these times the population exhibits evolutionary stasis (i.e., no change) with respect to the factor being measured. If we had a complete fossil record and looked for trends in some particular dimension, such as leg length, we would expect to see periods of no change alternating with fitful continuations or reversals in direction - like a weathervane in changeable, gusty weather.

German idealism rescued philosophy from the attack of British empiricism, and the struggle between the two became not merely a clash of different philosophical school, but a struggle for philosophy as such.

Morally, it is wrong to suppose the source of evil is outside oneself, that one is a vessel of holiness running over with virtue. Such a disposition is the best soil for a hateful and cruel fanaticism. It is as wrong to impute every wickedness to Jews, Freemasons, "intellectuals," as it is to blame all crimes on the bourgeoisie, the nobility, and the powers that were. No; the root of evil is in me as well, and I must take my share of the responsibility and the blame. That was true before the revolution and it is true still.

The Tories in England long imagined that they were enthusiastic about monarchy, the church, and the beauties of the old English Constitution, until the day of danger wrung from them the confession that they are enthusiastic only about ground rent.

As a general rule-never substitute the symbol for the thing signified, unless it is impossible to show the thing itself; for the child's attention is so taken up with the symbol that he will forget what it signifies.

The rush to California, for instance, and the attitude, not merely of merchants, but of philosophers and prophets, so called, in relation to it, reflect the greatest disgrace on mankind. That so many are ready to live by luck, and so get the means of commanding the labor of others less lucky, without contributing any value to society!

In summary, then, the set theoretic 'needs' of physics are surprisingly similar to the set theoretic needs of pure logic. Both disciplines need some set theory to function at all. Both disciplines can 'live' - but live badly - on the meager diet of only predicative sets. Both can live extremely happily on the rich diet of impredicative sets. Insofar, then, as the indispensability of quantification over sets is any argument for their existence - and we will discuss why it is in the next section - we may say that it is a strong argument for the existence of at least predicative sets, and a pretty strong, but not as strong, argument for the existence of impredicative sets.

Under no pretext should arms and ammunition be surrendered; any attempt to disarm the workers must be frustrated, by force if necessary.

A man of Intellect, of real and not sham Intellect, is by the nature of him likewise inevitably a man of nobleness, a man of courage, rectitude, pious strength; who, even because he is and has been loyal to the Laws of this Universe, is initiated into discernment of the same; to this hour a Missioned of Heaven; whom if men follow, it will be well with them; whom if men do not follow, it will not be well. Human Intellect, if you consider it well, is the exact summary of Human Worth; and the essence of all worth-ships and worships is reverence for that same.

To receive applause for works which do not demand all our powers hinders our advance towards a perfecting of our spirit. It usually means that thereafter we stand still.

Likewise, they call it "Chaos," which is Hesiod's first generator, because Chaos gives rise to everything else, as the monad does. It is also thought to be both "mixture" and "blending," "obscurity" and "darkness" thanks to the lack of articulation and distinction of everything which ensues from it. Anatolius says that it is called "matrix" and "matter," on the grounds that without it there is no number. The mark which signifies the monad is the source of all things.

Man's being is made of such strange stuff as to be partly akin to nature and partly not, at once natural and extranatural, a kind of ontological centaur, half immersed in nature, half transcending it.

Even if we consider not words by themselves but rules deciding what words may appropriately be produced in certain contexts - even if we consider, in computer jargon, programs for using words - unless those programs themselves refer to something extra-linguistic there is still no determinate reference that those words possess. This will be a crucial step in the process of reaching the conclusion that the Brain-in-a-Vat Worlders cannot refer to anything external at all (and hence cannot say that they are Brain-in-a-Vat Worlders).

Orwell's essay speaks to us today. It tells us that patriotism is the sine qua non of survival, and that it arises spontaneously in the ordinary human heart. It does not depend upon any grand narrative of triumph of the kind put about by the fascists and the communists, but grows from the habits of association that we British have been fortunate enough to inherit. We do not use grand and tainted honorifics like "la patrie" or "das Vaterland". We refer simply to this spot of earth, which belongs to us because we belong to it, have lived in it, loved it, defended it and established peace and prosperity within its borders.

I do not say this, that I think there should be no difference of opinions in conversation, nor opposition in men's discourses... 'Tis not the owning one's dissent from another, that I speak against, but the manner of doing it.

The worst evil is hardness of heart. Those who do not repent, who deliberately remain in their habits of sin, have the most to fear.

Nothing is so much to be feared as fear. Atheism may comparatively be popular with God himself.

"If a nation expects to be ignorant and free," said Jefferson, "it expects what never was and never will be."

I could show, that the same faction has, in one reign, promoted popular seditions, and, in the next, been a patron of tyranny; I could show, that they have all of them betrayed the public safety at all times, and have very frequently with equal perfidy made a market of their own cause, and their own associates. I could show how vehemently they have contended for names, and how silently they have passed over things of the last importance.

We are not to expect to be translated from despotism to liberty in a featherbed.

The knowledge of anything, since all things have causes, is not acquired or complete unless it is known by its causes. Therefore in medicine we ought to know the causes of sickness and health. And because health and sickness and their causes are sometimes manifest, and sometimes hidden and not to be comprehended except by the study of symptoms, we must also study the symptoms of health and disease. Now it is established in the sciences that no knowledge is acquired save through the study of its causes and beginnings, if it has had causes and beginnings; nor completed except by knowledge of its accidents and accompanying essentials. Of these causes there are four kinds: material, efficient, formal, and final.

The governing principles of chemical affinity are, that it is elective ; that it is definite ; that it determines the properties of the compound; and that analysis is possible.

Then the case is the same in all the other arts for the orator and his rhetoric; there is no need to know the truth of the actual matters, but one merely needs to have discovered some device of persuasion which will make one appear to those who do not know to know better than those who know.

Human intuitions are systematically biased. Evolutionary psychology explains how our moral intuitions and the rationalisations they spawn have been shaped by millennia of natural selection to maximise the inclusive fitness of our genes, not to track the welfare of other sentient beings impartially conceived. Many human cultures have found nothing intuitively wrong with aggressive warfare, slavery, wife-beating, infanticide or female genital mutilation. Ultimately, folk morality is a doomed enterprise as hopeless as folk physics. A mature posthuman ethics, I'd argue, must be committed to the well-being of all sentient life; and mature posthuman technology offers the means to deliver that commitment.

Technical progress and more comfortable living permit the systematic inclusion of libidinal components into the realm of commodity production and exchange. But no matter how controlled the mobilization of instinctual energy may be (it sometimes amounts to a scientific management of libido), no matter how much it may serve as a prop for the status quo-it is also gratifying to the managed individuals, just as racing the outboard motor, pushing the power lawn mower, and speeding the automobile are fun.

The perception of beauty is a moral test.

The business of art is no longer the communication of thoughts or feelings which are to be conceptually ordered, but a direct participation in an experience. The whole tendency of modern communication...is towards participation in a process, rather than apprehension of concepts.

The antagonism between science and religion, about which we hear so much, appears to me to be purely factitious - fabricated, on the one hand, by short-sighted religious people who confound a certain branch of science, theology, with religion; and, on the other, by equally short-sighted scientific people who forget that science takes for its province only that which is susceptible of clear intellectual comprehension; and that, outside the boundaries of that province, they must be content with imagination, with hope, and with ignorance.

By nature a philosopher is not in genius and disposition half so different from a street porter, as a mastiff is from a greyhound.

In speaking of the move from subjective to objective characterization, I wish to remain noncommittal about the existence of an endpoint, the completely objective intrinsic nature of the thing, which one might or might not be able to reach. It may be more accurate to think of objectivity as a direction in which the understanding can travel. And in understanding a phenomenon like lightning, it is legitimate to go as far away as one can from a strictly human viewpoint.But in the case of experience, on the other hand, the connexion with a particular point of view seems much closer. It is difficult to understand what could be meant by the objective character of an experience, apart from the particular point of view from which its subject apprehends it. After all, what would be left of what it was like to be a bat if one removed the viewpoint of the bat?

When scientists take part in activity they transform themselves from scientists into acting beings, that is, they become elements, data, facts; as soon as they reflect on their activity, however, they are re-transformed into scientists. The trained specialist qua scientist looks upon himself as a chain of judgments and inferences; qua member of society, he regard himself as a mere object. The same holds for everyone. The individual is divided into innumerable functions, the interconnection of which are unknown. In society a man is pater familias under one aspect, business man under another, thinker under a third; to be more precise, he is not a human being at all, but all these aspects and many more in an inevitable succession.

That, on the whole, if you have got the intrinsic qualities, you have got everything, and the preliminaries will prove attainable; but that if you have got only the preliminaries, you have yet got nothing. A man of real dignity will not find it impossible to bear himself in a dignified manner; a man of real understanding and insight will get to know, as the fruit of his very first study, what the laws of his situation are, and will conform to these.

To all Christian governments Christianity was not a rule of means but a means of rule; Christ was for the people, Machiavelli was preferred by the kings. The state in some measure had civilized man, but who would civilize the state?

Since men in their endeavors behave, on the whole, not just instinctively, like the brutes, nor yet like rational citizens of the world according to some agreed-on plan, no history of man conceived according to a plan seems to be possible, as it might be possible to have such a history of bees or beavers. One cannot suppress a certain indignation when one sees men's actions on the great world-stage and finds, beside the wisdom that appears here and there among individuals, everything in the large woven together from folly, childish vanity, even from childish malice and destructiveness. In the end, one does not know what to think of the human race, so conceited in its gifts.

I have always noticed that deeply and truly religious persons are fond of a joke, and I am suspicious of those who aren't.

It is not by prayer and humility that you cause things to go as you wish, but by acquiring a knowledge of natural laws.

Obviously, Anarchism, or any other social theory, making man a conscious social unit, will act as a leaven for rebellion.

The journalists have constructed for themselves a little wooden chapel, which they also call the Temple of Fame, in which they put up and take down portraits all day long and make such a hammering you can't hear yourself speak.

Truth springs from argument amongst friends.

Your worst sin is that you have destroyed and betrayed yourself for nothing.

Why is psychology the youngest of the empirical sciences? Why have we not long since discovered the unconscious and raised up its treasure-house of eternal images? Simply because we had a religious formula for everything psychic - and one that is far more beautiful and comprehensive than immediate experience. Though the Christian view of the world has paled for many people, the symbolic treasure-rooms of the East are still full of marvels that can nourish for a long time to come the passion for show and new clothes. What is more, these images - be they Christian or Buddhist or what you will - are lovely, mysterious, richly intuitive.

Terms must be constructed and appropriated so as to be fitted to enunciate simply and clearly true general propositions.
