[An] argument I always hear around the mathematics department [is that] mathematics helps you to think clearly. I have a very low opinion of this self-serving nonsense. In sports there is the concept of the specificity of skills: if you want to improve your racquetball game, don’t practice squash! I believe the same holds true for intellectual skills.

Otto Neurath

The pseudo rationalists do true rationalism a disservice if they pretend to have adequate insight exactly where strict rationalism excludes it on purely logical grounds. Rationalism sees its chief triumph in the clear recognition of the limits of actual insights.

Otto Neurath, ‘The Lost Wanderers of Descartes and the Auxiliary Motive’, in Philosophical Papers, 1913-1946, Dordrecht, 1983, p. 8

William James

Perhaps the commonest expression of this assumption that spiritual value is undone if lowly origin be asserted is seen in those comments which unsentimental people so often pass on their more sentimental acquaintances. Alfred believes in immortality so strongly because his temperament is so emotional. Fanny’s extraordinary conscientiousness is merely a matter of over-instigated nerves. William’s melancholy about the universe is due to bad digestion — probably his liver is torpid. Eliza’s delight in her church is a symptom of her hysterical constitution. Peter would be less troubled about his soul if he would take more exercise in the open air, etc. A more fully developed example of the same kind of reasoning is the fashion, quite common nowadays among certain writers, of criticising the religious emotions by showing a connection between them and the sexual life. Conversion is a crisis of puberty and adolescence. The macerations of saints, and the devotion of missionaries, are only instances of the parental instinct of self-sacrifice gone astray. For the hysterical nun, starving for natural life, Christ is but an imaginary substitute for a more earthly object of affection. And the like.

We are surely all familiar in a general way with this method of discrediting states of mind for which we have an antipathy. We all use it to some degree in criticising persons whose states of mind we regard as overstrained. But when other people criticise our own more exalted soul-flights by calling them “nothing but” expressions of our organic disposition, we feel outraged and hurt, for we know that, whatever be our organism’s peculiarities, our mental states have their substantive value as revelations of the living truth; and we wish that all this medical materialism could be made to hold its tongue.

Medical materialism seems indeed a good appellation for the too simple-minded system of thought which we are considering. Medical materialism finishes up Saint Paul by calling his vision on the road to Damascus a discharging lesion of the occipital cortex, he being an epileptic. It snuffs out Saint Teresa as an hysteric, Saint Francis of Assisi as an hereditary degenerate. George Fox’s discontent with the shams of his age, and his pining for spiritual veracity, it treats as a symptom of a disordered colon. Carlyle’s organ-tones of misery it accounts for by a gastro-duodenal catarrh. All such mental over- tensions, it says, are, when you come to the bottom of the matter, mere affairs of diathesis (auto-intoxications most probably), due to the perverted action of various glands which physiology will yet discover.

And medical materialism then thinks that the spiritual authority of all such personages is successfully undermined.

Let us ourselves look at the matter in the largest possible way. Modern psychology, finding definite psycho-physical connections to hold good, assumes as a convenient hypothesis that the dependence of mental states upon bodily conditions must be thorough- going and complete. If we adopt the assumption, then of course what medical materialism insists on must be true in a general way, if not in every detail: Saint Paul certainly had once an epileptoid, if not an epileptic seizure; George Fox was an hereditary degenerate; Carlyle was undoubtedly auto-intoxicated by some organ or other, no matter which, — and the rest. But now, I ask you, how can such an existential account of facts of mental history decide in one way or another upon their spiritual significance? According to the general postulate of psychology just referred to, there is not a single one of our states of mind, high or low, healthy or morbid, that has not some organic process as its condition. Scientific theories are organically conditioned just as much as religious emotions are; and if we only knew the facts intimately enough, we should doubtless see “the liver” determining the dicta of the sturdy atheist as decisively as it does those of the Methodist under conviction anxious about his soul. When it alters in one way the blood that percolates it, we get the methodist, when in another way, we get the atheist form of mind. So of all our raptures and our drynesses, our longings and pantings, our questions and beliefs. They are equally organically founded, be they of religious or of non-religious content.

To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one have already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our dis-beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of their possessor’s body at the time.

Michael Huemer

Some clustering of logically unrelated beliefs could be explained cognitively—for instance, by the hypothesis that some people tend to be good, in general, at getting to the truth (perhaps because they are intelligent, knowledgeable, etc.) So suppose that it is true both that affirmative action is just and that abortion is morally permissible. These issues are logically unrelated to each other; however, if some people are in general good at getting to the truth, then those who believe one of these propositions would be more likely to believe the other.

But note that, on this hypothesis, we would not expect the existence of an opposite cluster of beliefs. That is, suppose that liberal beliefs are, in general, true, and that this explains why there are many people who generally embrace this cluster of beliefs. (Thus, affirmative action is just, abortion is permissible, welfare programs are good, capital punishment is bad, human beings are seriously damaging the environment, etc.) Why would there be a significant number of people who tend to embrace the opposite beliefs on all these issues? It is not plausible to suppose that there are some people who are in general drawn toward falsity. Even if there are people who are not very good at getting to the truth (perhaps they are stupid, ignorant, etc.), their beliefs should be, at worst, unrelated to the truth; they should not be systematically directed away from the truth. Thus, while there could be a ‘true cluster’ of political beliefs, the present consideration strongly suggests that neither the liberal nor the conservative belief-cluster is it.

William James

I have just read your letter over again, and am grieved afresh at your melancholy tone about yourself. You ask why I am quiet, while you are so restless. Partly from the original constitution of things, I suppose; partly because I am less quiet than you suppose; only I once heard a proverb about a man consuming his own smoke, and I do so particularly in your presence because you, being so much more turbid, produce a reaction in me; partly because I am a few years older than you, and have not solved, but grown callous (I hear your sneer) to, many of the problems that now torture you. The chief reason is the original constitution of things, which generated me with fewer sympathies and wants than you, and also perhaps with a certain tranquil confidence in the right ordering of the Whole, which makes me indifferent in some circumstances where you would fret. Yours the nobler, mine the happier part! I think, too, that much of your uneasiness comes from that to which you allude in your letter your oscillatoriness, and your regarding each oscillation as something final as long as it lasts. There is nothing more certain than that every man’s life (except perhaps Harry Quincy’s) is a line that continuously oscillates on every side of its direction; and if you would be more confident that any state of tension you may at any time find yourself in will inevitably relieve itself, sooner or later, you would spare yourself much anxiety. I myself have felt in the last six months more and more certain that each man s constitution limits him to a certain amount of emotion and action, and that, if he insists on going under a higher pressure than normal for three months, for instance, he will pay for it by passing the next three months below par. So the best way is to keep moving steadily and regularly, as your mind becomes thus deliciously appeased (as you imagine mine to be; ah! Tom, what damned fools we are!). If you feel below par now, don t think your life is deserting you forever. You are just as sure to be up again as you are, when elated, sure to be down again. Six months, or any given cycle of time, is sure to see you produce a certain amount, and your fretful anxiety when in a stagnant mood is frivolous. The good time will come again, as it has come; and go too. I think we ought to be independent of our moods, look on them as external, for they come to us unbidden, and feel if possible neither elated nor depressed, but keep our eyes upon our work and, if we have done the best we could in that given condition, be satisfied.

William James, letter to Thomas Ward, June 8, 1866

David Chalmers

If reconstructive uploading will eventually be possible, how can one ensure that it happens? There have been billions of humans in the history of the planet. It is not clear that our successors will want to reconstruct every person who ever lived, or even every person of whom there are records. So if one is interested in immortality, how can one maximize the chances of reconstruction? One might try keeping a bank account with compound interest to pay them for doing so, but it is hard to know whether our financial system will be relevant in the future, especially after an intelligence explosion.

My own strategy is to write about a future of artificial intelligence and about uploading. Perhaps this will encourage our successors to reconstruct me, if only to prove me wrong.

William James

Two great maxims emerge from his treatment. The first is that in the acquisition of a new habit, or the leaving off of an old one, we must take care to launch ourselves with as strong and decided an initiative as possible. Accumulate all the possible circumstances which shall reenforce the right motives; put yourself assiduously in conditions that encourage the new way; make engagements incompatible with the old; take a public pledge, if the case allows; in short, envelop your resolution with every aid you know. This will give your new beginning such a momentum that the temptation to break down will not occur as soon as it otherwise might; and every day during which a breakdown is postponed adds to the chances of its not occurring at all.

The second maxim is: Never suffer an exception to occur till the new habit is securely rooted in your life. Each lapse is like the letting fall of a ball of string which one is carefully winding up; a single slip undoes more than a great many turns will wind again. Continuity of training is the great means of making the nervous system act infallibly right. […]

A third maxim may be added to the preceding pair: Seize the Very first possible opportunity to act on every resolution you make, and on every emotional prompting you may experience in the direction of the habits you aspire to gain. It is not in the moment of their forming, but in the moment of their producing motor effects, that resolves and aspirations communicate the new ‘set’ to the brain.

One need not be a consequentialist to find something odd in a Kantian’s proposal to donate $100 to a famine relief organization she happens to know is especially inefficient when there is a more efficient organization that will save more people standing by.

Ashlee Vance

For Gracias, the Tesla and SpaceX investor and Musk’s friend, the 2008 period told him everything he would ever need to know about Musk’s character. He saw a man who arrived in the United States with nothing, who had lost a child, who was being pilloried in the press by reporters and his ex-wife and who verged on having his life’s work destroyed. “He has the ability to work harder and endure more stress than anyone I’ve ever met,” Gracias said. “What he went through in 2008 would have broken anyone else. He didn’t just survive. He kept working and stayed focused.” That ability to stay focused in the midst of a crisis stands as one of Musk’s main advantages over other executives and competitors. “Most people who are under that sort of pressure fray,” Gracias said. “Their decisions go bad. Elon gets hyperrational. He’s still able to make very clear, long-term decisions. The harder it gets, the better he gets. Anyone who saw what he went through firsthand came away with more respect for the guy. I’ve just never seen anything like his ability to take pain.”

Ron Chernow

As to why God had singled out John D. Rockefeller for such spectacular bounty, Rockefeller always adverted to his own adherence to the doctrine of stewardship—the notion of the wealthy man as a mere instrument of God, a temporary trustee of his money, who devoted it to good causes. “It has seemed as if I was favored and got increase because the Lord knew that I was going to turn around and give it back.” Rockefeller said this in his late seventies, and one wonders whether the equation between moneymaking and money giving only entered his mind later. Yet even as a teenager, he took palpable pleasure in distributing money for charitable purposes, and he insisted that from an early date he discerned the intimate spiritual link between earning and dispensing money. “I remember clearly when the financial plan—if I may call it so— of my life was formed. It was out in Ohio, under the ministration of a dear old minister, who preached, ‘Get money: get it honestly and then give it wisely.’ I wrote that down in a little book.” This echoed John Wesley’s dictum, “If those who ‘gain all they can’ and ‘save all they can,’ will likewise ‘give all they can,’ then the more they will grow in grace.”

In this paper I have criticized AI researchers very harshly. Let me express my faith that people in other fields would, on inspection, be found to suffer from equally bad faults. Most AI workers are responsible people who are aware of the pitfalls of a difficult field and produce good work in spite of them. However, to say anything good about anyone is beyond the scope of this paper.

Alain de Botton

Despite our best efforts to clean it of its peculiarities, sex will never be either simple or nice in the ways we might like it to be. It is not fundamentally democratic or kind; it is bound up with cruelty, transgression and the desire for subjugation and humiliation It refuses to sit neatly on top of love, as it should. Tame it though we may try, sex has a recurring tendency to wreak havoc across our lives: it leads us to destroy our relationships, threatens our productivity and compels us to stay up too late in nightclubs talking to people whom we don’t like but whose exposed midriffs we nevertheless strongly wish to touch. Sex remains in absurd, and perhaps irreconcilable, conflict with some of our highest commitments and values.

Oliver Kamm

The title of this book encapsulates my reasoning. It’s taken from the English edition of Asterix the Gaul. The indomitable Gaul has just bashed some Roman legionaries. One of the Romans says, dazedly: ‘Vae victo, vae victis.’ Another observes: ‘We decline.’ The caption above this scene of destruction reads: ‘Accidence will happen.’

You have to believe me that this is funny. The first legionary’s Latin phrase means: ‘Woe to the one who has been vanquished, woe to those who have been vanquished.’ The scene is a riff on grammar. It was made up by Anthea Bell, the English translator of the Asterix books. She is my mother and I have stolen her joke. I’ll render it leaden by explaining why it appeals to me. Victo is the dative singular and victis is the dative plural. The legionary is literally declining, in the grammatical sense. The aspect of grammar that deals with declension and conjugation is called accidence.

Gregory Clark

In Guns, Germs, and Steel Jared Diamond suggested that geography, botany, and zoology were destiny. Europe and Asia pressed ahead economically, and remained ahead to the present day, because of accidents of geography. They had the kinds of animals that could be domesticated, and the orientation of the Eurasian land mass allowed domesticated plants and animals to spread easily between societies. But there is a gaping lacuna in his argument. In a modern world in which the path to riches lies through industrialization, why are bad-tempered zebras and hippos the barrier to economic growth in sub-Saharan Africa? Why didn’t the Industrial Revolution free Africa, New Guinea, and South America from their old geographic disadvantages, rather than accentuate their backwardness? And why did the takeover of Australia by the British propel a part of the world that had not developed settled agriculture by 1800 into the first rank among developed economies?

[A]s a blog author, while I realize that blog posts can be part of a balanced intellectual diet, I worry that I tempt readers to fill their intellectual diet with too much of the fashionably new, relative to the old and intellectually nutritious. Until you reach the state of the art, and are ready to be at the very forefront of advancing human knowledge, most of what you should read to get to that forefront isn’t today’s news, or even today’s blogger musings. Read classic books and articles, textbooks, review articles. Then maybe read focused publications (including perhaps some blog posts) on your chosen focus topic(s).

Nicholas Rescher

Since his philosophical writing adopted selflessness and self-abnegation, whereas Schopenhauer himself led the life of a self-centered curmudgeon in affluent comfort, the charge of hypocrisy and inconsistency was made against him.

Schopenhauer replied that it sufficed for a philosopher to examine the human condition and determine the best form of life for man: that he should also provide an example of it in his own proceedings was asking far too much.

Schopenhauer vividly illustrates the irony of the human condition where all too often the intellect acknowledges the advantage of going where the will is unwilling to follow. And since this tension between intellect and will was the keystone of his philosophy, Schopenhauer’s proceedings did perhaps manage after all to provide that example of living by one’s doctrine.

The problems which most perplex tennis players are not those deal- ing with the proper way to swing a racket. Books and professionals giving this information abound. Nor do most players complain excessively about physical limitations.

[W]hile the problem of interpersonal comparability of utility is a tricky one, it is not insoluble in principle. It is conceivable that, perhaps several hundred (or a thousand) years from now, neurology may have advanced to the stage where the level of happiness can be accurately correlated to some cerebral reaction that can be measured by a ‘eudaimonometer’. Hence the definition of social welfare [in terms of the sum total of individual happiness] is an objective definition, although the objects are the subjective feelings of individuals.

Carol Tavris & Elliot Aronson

Lyndon Johnson was a master of self-justification. According to his biographer Robert Caro, when Johnson came to believe in something, he would believe in it “totally, with absolute conviction, regardless of previous beliefs, or of the facts in the matter.” George Reedy, one of Johnson’s aides, said that he “had a remarkable capacity to convince himself that he held the principles he should hold at any given time, and there was something charming about the air of injured innocence with which he would treat anyone who brought forth evidence that he had held other views in the past. It was not an act… He had a fantastic capacity to persuade himself that the ‘truth’ which was convenient for the present was the truth and anything that conflicted with it was the prevarication of enemies. He literally willed what was in his mind to become reality.” Although Johnson’s supporters found this to be a rather charming aspect of the man’s character, it might well have been one of the major reasons that Johnson could not extricate the country from the quagmire of Vietnam. A president who justifies his actions only to the public might be induced to change them. A president who has justified his actions to himself, believing that he has the truth, becomes impervious to self-correction.

Most activists, in his experience, would launch big campaigns about big issues and do things that they guessed would be beneficial, like running television ads or sending out direct mail, but they never did the work to figure out whether what they were doing was actually changing policy.

Some performers manipulate the style of their product to shift the incentives of critics to pay attention. Richard Posner cites Shakespeare, Nietzsche, Wittgenstein, and Kafka as figures who owe part of their reputation to the enigmatic and perhaps even contradictory nature of their writings. Unclear authors, at least if they have substance and depth, receive more attention from critics and require more textual exegesis. Individual critics can establish their own reputations by studying such a writer and by promoting one interpretation of that writer’s work over another These same critics will support the inclusion of the writer in the canon, to promote the importance of their own criticism. In effect, deep and ambiguous writers are offering critics implicit invitations to serve as co-authors of a broader piece of work.

Generalization would lead to the recognition of value in possible future experiences, in the means to them, and in the lives of creatures other than ourselves. These values are not extra properties of goodness and badness, but just truths such as the following: If something I do will cause another creature to suffer, that counts against doing it. I can come to see that this is true by generalizing from the evident disvalue of my own suffering[.]

The existence of consciousness is both one of the most familiar and one of the most astounding things about the world. No conception of the natural order that does not reveal it as something to be expected can aspire even to the outline of completeness. And if physical science, whatever it may have to say about the origin of life, leaves us necessarily in the dark about consciousness, that shows that it cannot provide the basic form of intelligibility for this world. There must be a very different way in which things as they are make sense, and that includes the way the physical world is, since the problem cannot be quarantined in the mind.

It was a dull way of giving—writing checks rather than, say, becoming an aid worker in a distant country. There was a moral glamour in throwing over everything and leaving home and going somewhere dangerous that compensated for all sorts of privations. There was no glamour in staying behind, earning money, and donating it. It certainly wasn’t soul-stirring, to be thinking about money all the time. But so much depended on money, they knew—it took a callous kind of sentimentality to forget that. Money well spent could mean years of life, and money spent badly meant years of life lost.
