Parmenides: I was pleased with you, Socrates, because you would not discuss the doubtful question in terms of visible objects or in relation to them, but only with reference to what we conceive most entirely by the intellect and may call ideas… But if you wish to get better training, you must do something more than that; you must consider not only what happens if a particular hypothesis is true, but also what happens if it is not true.

...what the freedom is that I love, and that to which I think all men intitled. It is not solitary, unconnected, individual, selfish Liberty. As if every Man was to regulate the whole of his Conduct by his own will. The Liberty I mean is social freedom. It is that state of things in which Liberty is secured by the equality of Restraint; A Constitution of things in which the liberty of no one Man, and no body of Men and no Number of men, can find Means to trespass on the liberty of any Person, or any description of Persons in the Society. This kind of liberty is indeed but another name for Justice, as ascertained by wise Laws, and secured by well-constructed institutions.

Time is the wisest of all things that are; for it brings everything to light.

Only one thing matters: learning to be the loser.

If the only alternative to fascism we produce is a corporate-driven, milquetoast, neoliberal Democratic Party, fascism will come to America. Let us be very clear. It's like a Weimar America.

Living a minimally acceptable ethical life involves using a substantial part of our spare resources to make the world a better place. Living a fully ethical life involves doing the most good we can.

If the importance of science does not lie in its constituting the whole of human knowledge, even less does it lie, in my view, in its technological applications. Science at the best is a way of coming to know, and hopefully a way of acquiring some reverence for, the wonders of nature. The philosophical study of science, at the best, has always been a way of coming to understand both some of the nature and some of the limitations of human reason. These seem to me to be sufficient grounds for taking science and philosophy of science seriously; they do not justify science worship.

Marriage as a community of interests unfailingly means the degradation of the interested parties, and it is the perfidy of the world's arrangements that no one, even if aware of it, can escape such degradation. The idea might therefore be entertained that marriage without ignominy is a possibility reserved for those spared the pursuit of interests, for the rich. But the possibility is purely formal, for the privileged are precisely those in whom the pursuit of interests has become second-nature-they would not otherwise uphold privilege.

When men hire themselves out to shoot other men to order, asking nothing about the justice of their cause, I don't care if they are shot themselves.

Second, in the presence of this continuity of feeling, nominalistic maxims appear futile. There is no doubt about one idea affecting another, when we can directly perceive the one generally modified and shaping itself into the other. Nor can there any longer be any difficulty about one idea resembling another, when we can pass along the continuous field of quality from one to the other and back again to the point which we had marked.

The scene should be gently open'd, and his entrance made step by step, and the dangers pointed out that attend him from several degrees, tempers, designs, and clubs of men. He should be prepared to be shocked by some, and caress'd by others; warned who are like to oppose, who to mislead, who to undermine him, and who to serve him. He should be instructed how to know and distinguish them; where he should let them see, and when dissemble the knowledge of them and their aims and workings.

Saying is one thing, doing another.

The essence of the belief that bats have experience is that there is something that it is like to be a bat. Now we know that most bats (the microchiroptera, to be precise) perceive the external world primarily by sonar, or echolocation. ... But bat sonar, though clearly a form of perception, is not similar in its operation to any sense that we possess, and there is no reason to suppose that it is subjectively like anything we can experience or imagine. This appears to create difficulties for the notion of what it is like to be a bat.

You shall have joy, or you shall have power, said God; you shall not have both.

It is in this way that all my books have been composed. They were always written at least twice over; a first draft of the entire work was completed to the very end of the subject, then the whole begun again de novo; but incorporating, in the second writing, all sentences and parts of sentences of the old draft, which appeared as suitable to my purpose as anything which I could write in lieu of them. I have found great advantages in this system of double redaction. It combines, better than any other mode of composition, the freshness and vigour of the first conception, with the superior precision and completeness resulting from prolonged thought. In my own case, moreover, I have found that the patience necessary for a careful elaboration of the details of composition and expression, costs much less effort after the entire subject has been once gone through, and the substance of all that I find to say has in some manner, however imperfect, been got upon paper.

The very proclaimers of "America first" have long before this betrayed the fundamental principles of real Americanism...the other truly great Americans who aimed to make of this country a haven of refuge, who hoped that all the disinherited and oppressed people in coming to these shores would give character, quality and meaning to the country.

The Ideal Man of the eighteenth century was the Rationalist; of the seventeenth, the Christian Stoic; of the Renaissance, the Free Individual; of the Middle Ages, the Contemplative Saint. And what is our Ideal Man? On what grand and luminous mythological figure does contemporary humanity attempt to model itself? The question is embarrassing. Nobody knows. And, in spite of all the laudable efforts of the Institute for Intellectual Co-operation to fabricate an acceptable Ideal Man for the use of Ministers of Education, nobody, I suspect, will know until such time as a major poet appears upon the scene with the unmistakable revelation. Meanwhile, one must be content to go on piping up for reason and realism and a certain decency.

When the real is no longer what it was, nostalgia assumes its full meaning. "The Precession of Simulacra,"

The possibility of peace, on whose behalf many are working, might perhaps become actual because the technical advances in offensive weapons make the prospect of a European war so disastrous, and because, if the nations were at grips again, even the victorious aggressor would be ruined. But there still remains open the possibility of a new war which, more dreadful than any that have preceded it would make an end of contemporary Europeans.

There are only Epicureans, either crude or refined; Christ was the most refined.

This is the value of the Communities; not what they have done, but the revolution which they indicate as on the way.

Ambition is the death of thought.

Nothing in this book is true.

Society triumphs over many. They wish to regenerate the world with their institutions, with their moral philosophy, with their love. Then they sink to living from breakfast till dinner, from dinner till tea, with a little worsted work, and to looking forward to nothing but bed. When shall we see a life full of steady enthusiasm, walking straight to its aim, flying home, as that bird is now, against the wind - with the calmness and the confidence of one who knows the laws of God and can apply them?

There is one particular property of living things, however, that I want to single out as explicable only by Darwinian selection. This property is the one that has been the recurring topic of this book: adaptive complexity.

Whoever drinks from my mouth will become like me; I myself shall become that person, and the hidden things will be revealed to him.

Both of us victims of the same twentieth-century plague. Not the Black Death, this time; the Grey Life.

Sabbath rest does not follow creation; it brings creation to completion.

It costs a beautiful person no exertion to paint her image on our eyes; yet how splendid is that benefit! It costs no more for a wise soul to convey his quality to other men.

No man is bound by the words themselves, either to kill himselfe, or any other man.

I have needed God every day to defend myself against the abundance of thoughts.

Mysticism is, in essence, little more than a certain intensity and depth of feeling in regard to what is believed about the universe.

Do you know that ages will pass and mankind will proclaim in its wisdom and science that there is no crime and, therefore no sin, but that there are only hungry people. "Feed them first and then demand virtue of them!" - that is what they will inscribe on their banner which they will raise against you and which will destroy your temple.

It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest most uninteresting person you talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree helping each other to one or the other of these destinations. It is in the light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all of our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilizations - these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit - immortal horrors or everlasting splendors.

The propositions which are true and evident must of necessity be employed even by those who contradict them.

To forget the wrongs you receive, is to remedy them.

I can imagine no man who will look with more horror on the End than a conscientious revolutionary who has, in a sense sincerely, been justifying cruelties and injustices inflicted on millions of his contemporaries by the benefits which he hopes to confer on future generations: generations who, as one terrible moment now reveals to him, were never going to exist. Then he will see the massacres, the faked trials, the deportations, to be all ineffaceably real, an essential part, his part, in the drama that has just ended: while the future Utopia had never been anything but a fantasy.

To save the world requires faith and courage: faith in reason, and courage to proclaim what reason shows to be true.

The suppression of liberty is always likely to be irrational.

Can the "word" be pinned down to either one period or one church? All churches are, of course, only more or less unsuccessful attempts to represent the unseen to the mind.

Psychological disorders are symptoms of a blocked story... The patient is cured the moment she narrates herself free.

Weisinger, a couple of years ago, made up the following story: "Isaac Asimov was asked how Superman could fly faster than the speed of light, which was supposed to be an absolute limit. To this Asimov replied, 'That the speed of light is a limit is a theory; that Superman can travel faster than light is a fact.'"

The advantage of pure, and the disadvantage of impure air are experienced each time we breathe, and all who understand the causes of disease know that an impure atmosphere is most unfavourable to the enjoyment of health, and an efficient cause to shorten human existence within the natural life of man. It is therefore most desirable that decisive measures should be devised and generally adopted to ensure to all a pure atmosphere, in which to live during their lives.

I was a solitary, shy, priggish youth. I had no experience of the social pleasures of boyhood and did not miss them. But I liked mathematics, and mathematics was suspect because it has no ethical content. I came also to disagree with the theological opinions of my family, and as I grew up I became increasingly interested in philosophy, of which they profoundly disapproved. Every time the subject came up they repeated with unfailing regularity, 'What is mind? No matter. What is matter? Never mind.' After some fifty or sixty repetitions, this remark ceased to amuse me.

Falling in love is the one illogical adventure, the one thing of which we are tempted to think as supernatural, in our trite and reasonable world. The effect is out of all proportion with the cause. Two persons, neither of them, it may be, very amiable or very beautiful, meet, speak a little, and look a little into each other's eyes. That has been done a dozen or so of times in the experience of either with no great result. But on this occasion all is different. They fall at once into that state in which another person becomes to us the very gist and centrepoint of God's creation, and demolishes our laborious theories with a smile; in which our ideas are so bound up with the one master-thought that even the trivial cares of our own person become so many acts of devotion, and the love of life itself is translated into a wish to remain in the same world with so precious and desirable a fellow-creature.

The heavens are as deep as our aspirations are high.

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.

Choose a wife who is of character, because that one is good who in the end is more respected.
