“Yesterday I went for a long walk in the spring sunshine with Trudy Eyges and Richard Feynman. Feynman is the young American professor, half genius and half buffoon, who keeps all physicists and their children amused with his effervescent vitality. He has, however, as I have recently learned, a great deal more to him than that, and you may be interested in his story. The part of it with which I am concerned began when he arrived at Los Alamos; there he found and fell in love with a brilliant and beautiful girl, who was tubercular and had been exiled to New Mexico in the hope of stopping the disease. When Feynman arrived, things had got so bad that the doctors gave her only a year to live, but he determined to marry her, and marry her he did; and for a year and a half, while working at full pressure on the project, he nursed her and made her days cheerful. She died just before the end of the war…

As Feynman says, anyone who has been happily married once cannot long remain single, and so yesterday we were discussing his new problem, this time again a girl in New Mexico with whom he is desperately in love. This time the problem is not tuberculosis, but the girl is a Catholic. You can imagine all the troubles this raises, and if there is one thing Feynman could not do to save his soul, it is to become a Catholic himself. So we talked and talked and sent the sun down the sky and went on talking in the darkness. At the end of it, Feynman was no nearer to the solution of his problems, but it must have done him good to get them off his chest. I think that he will marry the girl and that it will be a success, but far be it from me to give advice to anybody on such a subject. […]

I came to the conclusion that he is an exceptionally well-balanced person, whose opinions are always his own and not other people’s. He is very good at getting on with people, and as we came West, he altered his voice and expressions unconsciously to fit his surroundings, until he was saying ‘I don’t know noth’n’ like the rest of them.

Feynman’s young lady turned him down when he arrived in Albuquerque, having attached herself in his absence to somebody else. He stayed there for only five days to make sure, then left her for good and spent the rest of the summer enjoying himself with horses in New Mexico and Nevada.”

A Secular Scientist’s Argument against the New Atheists

David Berlinski and Christopher Hitchens

Moderator: Dr. Berlisnki, you’re not a Christian, and indeed, you’re not religious as I understand it. Why do you argue for a Judeo-Christian influence in society?

David Berlisnki: I presume you are not asking me in the hopes of a personal declaration. And I won’t say that this secular Jew has a remarkable degree of authority when it comes to these moral events: after all, I have lived my own life under the impress of having a good time, all the time. On the other hand, it doesn’t hurt to hear these words from someone such as myself, because at least you are hearing them from someone with no conceivable bias in their favor.

In its largest aspect, Western science is of course an outgrowth of Judeo-Christian tradition, especially to the extent, perhaps only to the extent, that it is committed to the principle that the manifest universe contains a latent structure that can be discovered by the intellect of man. I think this is true. I don’t think this is very far from Gerard Manley Hopkins’ declaration that, ‘the world is charged with the grandeur of God.’ […]

You know, Stephen Hawking just published a book, one explaining, again, how everything began — why it’s there, why we shouldn’t worry about God, et cetera. And to paraphrase the claim that he now makes: having given up on “A” through “L”, he now champions something called “M-theory” to explain how the universe popped into existence. I respect Hawking as a reputable physicist. But I can tell you this: What is lamentably lacking in every one of these discussions is that coruscating spirit of skepticism which a Christopher Hitchens or a Richard Dawkins would bring to religious claims, and then lapses absurdly when it comes to naturalistic and scientific claims about the cosmos.

Surely, we should have the sophistication to wonder at any asseveration of the form that the universe just blasted itself into existence following the laws of M-theory — a theory no one can understand, whose mathematical formulism hasn’t been completed, which has never once been tested in any laboratory on the face of the earth…

Finally, the fact that the earth, our home, is a small part of the physical universe does not mean it is not the center of the universe. That is a non sequitur. After all, no one would argue, least of all Mr. Hitchens, that the doctrine that home is where the heart lies is rendered false by distance. We should be very careful about making these claims. I agree that the universe is very big; there are lots of galaxies and amazing things. And there is certainly some biological continuity between humans and the animals that came before us. But as for the central religious claim that this particular place is blessed and important, that’s different. No doctrine about physical size rebuts it…

And as to why should a secular Jew open his mouth to questions pertaining to the Christian religion? It’s a big tent. I’m presuming I would be welcomed.

__________

An excerpt from Berlinski’s 2010 debate with Christopher Hitchens. Berlinski’s erudition reaches almost comical heights in this debate, which is, in my opinion, one of the more compelling Hitch ever did. I like the whole thing, but you can watch the pulled section below.

Galileo Squares Faith and Reason

Galileo

“I think in the first place that it is very pious to say and prudent to affirm that the holy Bible can never speak untruth — whenever its true meaning is understood.  But I believe nobody will deny that it is often very abstruse, and may say things which are quite different from what its bare words signify. Hence in expounding the Bible if one were always to confine oneself to the unadorned grammatical meaning, one might fall into error. Not only contradictions and propositions far from true might thus be made to appear in the Bible, but even grave heresies and follies…

It is necessary for the Bible, in order to be accommodated to the understanding of every man, to speak many things which appear to differ from the absolute truth so far as the bare meaning of the words is concerned. But Nature, on the other hand, is inexorable and immutable; she never transgresses the laws imposed upon her, or cares a whit whether her abstruse reasons and methods of operation are understandable to men. For that reason it appears that nothing physical which sense experience sets before our eyes, or which necessary demonstrations prove to us, ought to be called in question (much less condemned) upon the testimony of biblical passages which may have some different meaning beneath their words. For the Bible is not chained in every expression to conditions as strict as those which govern all physical effects; nor is God any less excellently revealed in Nature’s actions than in the sacred statements of the Bible…

It follows as a necessary consequence that, since the Holy Ghost did not intend to teach us whether heaven moves or stands still, whether its shape is spherical or like a discus or extended in a plane, nor whether the earth is located at its center or off to one side, then so much the less was it intended to settle for us any other conclusion of the same kind. And the motion or rest of the earth and the sun is so closely linked with the things just named, that without a determination of the one, neither side can be taken in the other matters. Now if the Holy Spirit has purposely neglected to teach us propositions of this sort as irrelevant to the highest goal (that is, to our salvation), how can anyone affirm that it is obligatory to take sides on them, that one belief is required by faith, while the other side is erroneous? Can an opinion be heretical and yet have no concern with the salvation of souls? Can the Holy Ghost be asserted not to have intended teaching us something that does concern our salvation?

I would say here something that was heard from an ecclesiastic of the most eminent degree: ‘That the intention of the Holy Ghost is to teach us how one goes to heaven, not how heaven goes.'”

Steven Pinker: What Are Cuss Words and Why Do We Use Them?

Steven Pinker

Questioner: You say that most swear words are found in the following categories: sex, religion, excretion, death, infirmity, or disfavored groups. Can you give us an indication of why we find these particular things worthy of swearing about?

Steven Pinker: Each one of the categories from which we draw our taboo words involves negative emotion. In the case of sexual swearing, it’s the revulsion at sexual depravity, and just in general the high emotion that surrounds sexuality, even in the most liberated cultures. In the case of disfavored groups, say taboo terms for ethnic and racial minorities, it’s hatred and contempt for other peoples. In the case of religious swearing, it’s awe of the power of the divine. In the case of death and disease, it’s dread of infirmity and death.

So in each case, there’s a strong negative emotion. And I think the essence of swearing is the power to trigger a negative thought in the mind of your listener through the use of words. Now why would we want to do it?

There are a number of different ways in which people swear. Sometimes we do it in order to remind people how awful the objects or activities are. If we want people to not think about how terrible feces are, we use the word “feces.” If we want to remind them of how disgusting it all is, we use the word “shit.”

Likewise, if you’re talking about sex in a positive context, you’d be likely to use the phrase “make love,” but if you talk about someone who’s exploiting someone else, you might say, “Oh he’s fucking his secretary.” And the word is deliberately used to highlight that which is most offensive about the activity.

But we also use curse words cathartically. You hit your thumb with a hammer, and you start blurting out words having to do with theology (“damn”) or excretion (“shit”) or sexuality (“fuck”).

If you stub your toe and you yell out “oh shit!” it has nothing to do with feces, other than the fact that feces are unpleasant and stubbing your toe is unpleasant. […]

The swear words that you speak advertise to a real or sometimes virtual audience that you are currently in the throes of some extremely unpleasant emotion. And in that regard, swearing overlaps with other exclamations in the language, like “burrrr” if you’re cold, or “ah ha” or “mhmm” or “yuck”, which also have no syntax – you just blurt them out as individual words – but they still convey a particular emotion.

And in addition, as we’ve mentioned before, many sexual idioms have a rather unflattering image of sex as an act which damages or exploits a woman. Not only “we got screwed,” but “oh my printer is fucked up” – meaning broken, damaged.

So certainly over-use of sexual swearing can feel offensive to women. For that reason and many others, I avoid it. And as with any other aspect of language use, it’d be common sense and common courtesy to anticipate how the language will affect your audience, depending on whether it’s male or female, younger or older, in a formal setting or more casual setting. And whether it’s used with a straight face or ironically, swearing can be more or less offensive, and any careful speaker ought to anticipate these effects.

Hitler Kicks out Einstein

Adolf Hitler in Color

“Early in April 1933, the German government passed a law declaring that Jews (defined as anyone with a Jewish grandparent) could not hold an official position, including at the Academy or at the universities. Among those forced to flee were fourteen Nobel laureates and twenty-six of the sixty professors of theoretical physics in the country. Fittingly, such refugees from fascism who left Germany or the other countries it came to dominate — Einstein, Edward Teller, Victor Weisskopf, Hans Bethe, Lise Meitner, Niels Bohr, Enrico Fermi, Otto Stern, Eugene Wigner, Leó Szilárd, and others — helped to assure that the Allies rather than the Nazis first developed the atom bomb.

Planck tried to temper the anti-Jewish policies, even to the extent of appealing to Hitler personally. ‘Our national policies will not be revoked or modified, even for scientists,’ Hitler thundered back. ‘If the dismissal of Jewish scientists means the annihilation of contemporary German science, then we shall do without science for a few years!’

Among those fleeing the Nazi purge was Max Born, who with his tart-tongued wife, Hedwig, ended up in England. ‘I have never had a particularly favorable opinion of the Germans,’ Einstein wrote when he received the news. ‘But I must confess that the degree of their brutality and cowardice came as something of a surprise.’ Born took it all rather well, and he developed, like Einstein, a deeper appreciation for his heritage.

The Germans were all a bad breed, Einstein insisted, ‘except a few fine personalities (Planck 60% noble, and Laue 100%).’ Now, in this time of adversity, they could at least take comfort that they were thrown together with their true kinsmen. ‘For me the most beautiful thing is to be in contact with a few fine Jews — a few millennia of a civilized past do mean something after all.’

Having found himself deposited in Belgium… [Einstein] rented a house on the dunes of Le Coq sur Mer, a resort near Ostend, where he could contemplate, and Mayer could calculate, the universe and its waves in peace…

Peace, however, was elusive. Even by the sea he could not completely escape the threats of the Nazis. The newspapers reported that his name was on a list of assassination targets, and one rumor had it that there was a $5,000 bounty on his head. Upon hearing this, Einstein touched that head and cheerfully proclaimed, ‘I didn’t know it was worth that much!'”

From Walter Isaacson’s biography Einstein: His Life and Universe.

Today marks the 69th anniversary of Hitler’s suicide and the Allies’ final push on Berlin. In his short biography of the Führer, A.N. Wilson establishes the bogus philosophical underpinnings of the Final Solution, reflecting on the ways in which these deranged justifications wound up backfiring in unexpected ways:

[Hitler] often discoursed upon… the fact that ‘the Jew’ was always on the look-out to destroy ‘the natural order’ by ‘sleight of hand’: ‘The Jew introduced Christianity into the ancient world — in order to ruin it — re-opened the same breach in modern times — this time taking as his pretext the social question. It’s the same sleight of hand as before. Just as Saul was changed into St. Paul, Mordechai became Karl Marx…’ He had decided that ‘the people that is rid of the Jews returns spontaneously to the natural order.’

Already, by the middle of the war, Germans were beginning to recognize what it felt like to be on the way towards achieving natural order. For one thing, they had toothache, since most of the dentists in Germany had been deported or gone into exile. For another, they had very few nuclear physicists left, and those who had gone were helping the Americans pioneer nuclear weaponry. The fortunate universities of Britain and America now had their Albert Einstein, their Ernst Gombrich, their Eduard Fraenkel to adorn their faculties, thanks to the German Leader’s belief that such individuals were undermining the natural order.

Is It Possible to Step Outside the Universe?

Bill Bryson

“Now the question that has occurred to all of us at some point is: what would happen if you traveled out to the edge of the universe and, as it were, put your head through the curtains? Where would your head be if it were no longer in the universe? What would you find beyond?

The answer, disappointingly, is that you can never get to the edge of the universe. That’’s not because it would take too long to get there— — though of course it would — but because even if you traveled outward and outward in a straight line, indefinitely and pugnaciously, you would never arrive at an outer boundary. Instead, you would come back to where you began (at which point, presumably, you would rather lose heart in the exercise and give up). The reason for this is that the universe bends, in a way we can’’t adequately imagine, in conformance with Einstein’’s theory of relativity… [W]e are not adrift in some large, ever-expanding bubble. Rather, space curves, in a way that allows it to be boundless but finite. Space cannot even properly be said to be expanding because, as the physicist and Nobel laureate Steven Weinberg notes, “’solar systems and galaxies are not expanding, and space itself is not expanding.”’ Rather, the galaxies are rushing apart. It is all something of a challenge to intuition. Or as the biologist J. B. S. Haldane once famously observed: “’The universe is not only queerer than we suppose; it is queerer than we can suppose.'”

Einstein Breaks Up with His First Girlfriend

Young Albert Einstein

“It fills me with a peculiar kind of satisfaction that now I myself have to taste some of the pain that I brought upon the dear girl through my thoughtlessness and ignorance of her delicate nature. Strenuous intellectual work and looking at God’s nature are the reconciling, fortifying yet relentlessly strict angels that shall lead me through all of life’s troubles. If only I were able to give some of this to the good child.

And yet, what a peculiar way this is to weather the storms of life—in many a lucid moment I appear to myself as an ostrich who buries his head in the desert sand so as not to perceive the danger. One creates a small little world for oneself, and as lamentably insignificant as it may be in comparison with the perpetually changing size of real existence, one feels miraculously great and important, just like a mole in his self-dug hole. — But why denigrate oneself, others take care of that when necessary, therefore let’s stop.”

__________

A section of a letter written by Albert Einstein to the mother of his then- (and soon to be ex-) girlfriend.

In this letter, an 18-year-old Einstein is writing to Pauline Winteler (who he addresses as “Momma”), the mother of his first girlfriend, Marie Winteler, who has invited him to stay at the family’s country house. Einstein declines, citing that he would not want to lead on young Marie (who’s become, as they say, clingy) any more than he already has. It is a remarkably discerning and introspective letter, which illustrates not only the emotional and social maturity of Einstein, but also his becoming self-aware that physics is not merely something he wants to do — it is something he must do.

I first read this letter in Walter Isaacson’s Einstein: His Life and Universe. And as Isaacson continually notes, it is oft-forgotten that unlike the scientist-stereotype, Einstein loved women, and they reciprocated. In descriptions of him as a young man, he is characterized as darkly handsome, with an insouciance towards all things establishment that cast him as a rebel — two traits which the girls whom he pursued never failed to notice with endearment.

Albert Einstein

In his text, Isaacson bookends his quoting of this letter with the following analysis:

Einstein’s new bohemian life and old self-absorbed nature made it unlikely that he would continue his relationship with Marie Winteler, the sweet and somewhat flighty daughter of the family he had boarded with in Aarau. At first, he still sent her, via the mail, baskets of his laundry, which she would wash and then return. Sometimes there was not even a note attached, but she would cheerfully try to please him. In one letter she wrote of ‘crossing the woods in the pouring rain’ to the post office to send back his clean clothes. ‘In vain did I strain my eyes for a little note, but the mere sight of your dear handwriting in the address was enough to make me happy.’…

But he wanted to break off the relationship. In one of his first letters after arriving at the Zurich Polytechnic, he suggested that they refrain from writing each other. ‘My love, I do not quite understand a passage in your letter,’ she replied. ‘You write that you do not want to correspond with me any longer, but why not, sweetheart? … You must be quite annoyed with me if you can write so rudely.’ Then she tried to laugh off the problem: ‘But wait, you’ll get some proper scolding when I get home.’…

Einstein’s coolness toward Marie Winteler can seem, from our vantage, cruel. Yet relationships, especially those of teenagers, are hard to judge from afar. They were very different from each other, particularly intellectually. Marie’s letters, especially when she was feeling insecure, often descended into babble… Whoever was to blame, if either, it was not surprising that they ended up on different paths. After her relationship with Einstein ended, Marie lapsed into a nervous depression, often missing days of teaching, and a few years later married the manager of a watch factory. Einstein, on the other hand, rebounded from the relationship by falling into the arms of someone who was just about as different from Marie as could be imagined…

That girl to which Isaacson hints is the brilliant Mileva Marić, a student (and one of the only females) at the Zurich Polytechnic, who would later become Einstein’s first wife.

Albert Einstein

“We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangement of the books but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God. We see the universe marvelously arranged and obeying certain laws but only dimly understand these laws. Our limited minds grasp the mysterious force that moves the constellations. I am fascinated by Spinoza’s pantheism, but admire even more his contribution to modern thought because he is the first philosopher to deal with the soul and body as one, and not two separate things.”

Albert Einstein, in a quotation pulled from the first chapter of Max Jammer’s excellent Einstein and Religion: Physics and Theology.*

“The modesty of Sir Isaac Newton… arose from the depth and extent of his knowledge, which showed him what a small portion of nature he had been able to examine… a short time before his death he uttered this memorable sentiment:

‘I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.'”

Isaac Newton, as quoted by Sir David Brewster in volume II of his Memoirs of the Life, Writings, and Discoveries of Sir Isaac Newton.**

“We go about our daily lives understanding almost nothing of the world… Except for children (who don’t know enough not to ask the important questions), few of us spend much time wondering why nature is the way it is; where the cosmos came from, or whether it was always here; if time will one day flow backward and effects precede causes; or whether there are ultimate limits to what humans can know.”

Carl Sagan, writing in the introduction to Stephen Hawking’s A Brief History of Time.

__________

Neil deGrasse Tyson: I’m often asked by parents what advice can I give them to help get kids interested in science? And I have only one bit of advice: get out of their way. Kids are born curious. Period. I don’t care about your economic background. I don’t care what town you’re born in, what city, what country. If you’re a child, you are curious about your environment. You’re overturning rocks. You’re plucking leaves off of trees and petals off of flowers, looking inside, and you’re doing things that create disorder in the lives of the adults around you.  

And so then so what do adults do? They say, “Don’t pluck the petals off the flowers. I just spent money on that. Don’t play with the egg. It might break. Don’t….”  Everything is a don’t. We spend the first year teaching them to walk and talk and the rest of their lives telling them to shut up and sit down.

So you get out of their way. And you know what you do? You put things in their midst that help them explore. Help ‘em explore. Why don’t you get a pair of binoculars, just leave it there one day? Watch ‘em pick it up. And watch ‘em look around. They’ll do all kinds of things with it.

For me at age 11, I had a pair of binoculars and looked up to the moon, and the moon wasn’t just bigger, it was better. There were mountains and valleys and craters and shadows. And it came alive.”

* I’ve hosted the PDF of the first chapter of Jammer’s book. For some context, however, the quote cited above occurs on page 48. Jammer follows it with the following clarification of Einstein’s theology:

“…Rabbi Herbert S. Goldstein of the Institutional Synagogue in New York cabled Einstein, ‘Do you believe in God? Stop. Prepaid reply fifty words.’ Einstein replied, ‘I believe in Spinoza’s God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with fates and actions of human beings.’ Rabbi Goldstein commented that this reply

‘very clearly disproves . . . the charge of atheism made against Einstein. In fact, quite the reverse is true. Spinoza, who is called “the God-intoxicated man” and who saw God manifest in all of nature, certainly could not be called an atheist. . . . Einstein’s theory, if carried out to its logical conclusions would bring mankind a scientific formula for monotheism. He does away with all thought of dualism or pluralism. There can be no room for any aspect of polytheism.'”

** Could Newton have possibly read John Milton’s Paradise Regained, which was published in 1671, when the former would have been twenty-nine?

In Book Four of the poem, Lines 327 to 330 read:

Deep verst in books and shallow in himself,
Crude or intoxicate, collecting toys,
And trifles for choice matters, worth a spunge;
As Children gathering pebbles on the shore.

Einstein and the God that Doesn’t Play Dice

Albert Einstein

“In his maturity, Einstein more firmly believed that there was an objective ‘reality’ that existed whether or not we could observe it. The belief in an external world independent of the person observing it, he repeatedly said, was the basis of all science.

In addition, Einstein resisted quantum mechanics because it abandoned strict causality and instead defined reality in terms of indeterminacy, uncertainty, and probability. A true disciple of Hume would not have been troubled by this. There is no real reason—other than either a metaphysical faith or a habit ingrained in the mind—to believe that nature must operate with absolute certainty. It is just as reasonable, though perhaps less satisfying, to believe that some things simply happen by chance. Certainly, there was mounting evidence that on the subatomic level this was the case.

But for Einstein, this simply did not smell true. The ultimate goal of physics, he repeatedly said, was to discover the laws that strictly determine causes and effects. ‘I am very, very reluctant to give up complete causality,’ he told Max Born.

His faith in determinism and causality reflected that of his favorite religious philosopher, Baruch Spinoza. ‘He was utterly convinced,’ Einstein wrote of Spinoza, ‘of the causal dependence of all phenomena, at a time when the success of efforts to achieve a knowledge of the causal relationship of natural phenomena was still quite modest.’ It was a sentence that Einstein could have written about himself, emphasizing the temporariness implied by the word ‘still,’ after the advent of quantum mechanics.

Like Spinoza, Einstein did not believe in a personal God who interacted with man. But they both believed that a divine design was reflected in the elegant laws that governed the way the universe worked.

This was not merely some expression of faith. It was a principle that Einstein elevated (as he had the relativity principle) to the level of a postulate, one that guided him in his work. ‘When I am judging a theory,’ he told his friend Banesh Hoffmann, ‘I ask myself whether, if I were God, I would have arranged the world in such a way.’

When he posed that question, there was one possibility that he simply could not believe: that the good Lord would have created beautiful and subtle rules that determined most of what happened in the universe, while leaving a few things completely to chance. It felt wrong. ‘If the Lord had wanted to do that, he would have done it thoroughly, and not kept to a pattern . . . He would have gone the whole hog. In that case, we wouldn’t have to look for laws at all.’

This led to one of Einstein’s most famous quotes, written to Max Born, the friend and physicist who would spar with him over three decades on this topic. ‘Quantum mechanics is certainly imposing,’ Einstein said. ‘But an inner voice tells me that it is not yet the real thing. The theory says a lot, but it does not really bring us any closer to the secrets of the Old One. I, at any rate, am convinced that He does not play dice.’

Thus it was that Einstein ended up deciding that quantum mechanics, though it may not be wrong, was at least incomplete. There must be a fuller explanation of how the universe operates, one that would incorporate both relativity theory and quantum mechanics. In doing so, it would not leave things to chance.”

Steven Pinker on Feminism

Steven Pinker

“I am a feminist. I believe that women have been oppressed, discriminated against, and harassed for thousands of years. I believe that the two waves of the feminist movement in the 20th century are among the proudest achievements of our species, and I am proud to have lived through one of them, including the effort to increase the representation of women in the sciences.

But it is crucial to distinguish the moral proposition that people should not be discriminated against on account of their sex — which I take to be the core of feminism — and the empirical claim that males and females are biologically indistinguishable. They are not the same thing. Indeed, distinguishing them is essential to protecting the core of feminism. Anyone who takes an honest interest in science has to be prepared for the facts on a given issue to come out either way. And that makes it essential that we not hold the ideals of feminism hostage to the latest findings from the lab or field. Otherwise, if the findings come out as showing a sex difference, one would either have to say, ‘I guess sex discrimination wasn’t so bad after all,’ or else furiously suppress or distort the findings so as to preserve the ideal. The truth cannot be sexist. Whatever the facts turn out to be, they should not be taken to compromise the core of feminism.

From Steven Pinker, in his debate with Elizabeth Spelke on the topic of Science and Gender. You can find more of Pinker’s thoughts in his superb collection Language, Cognition, and Human Nature: Selected Articles.

Since his breakout book The Blank Slate: The Modern Denial of Human Nature, Pinker has outlined and continually advocated a conception of human nature which I find extremely compelling. It’s foundational claim is that we are not plastic in the way twentieth-century behaviorists would suggest. Human nature is not malleable in any robust sense of the term; but instead it is very rigidly pre-programmed by our biology, which is — perhaps not intuitively — the reason for our complex abilities and variations. The fact that, say, we are wired to acquire a rigid grammatical structure in childhood, and hence speak a language, is what allows us to communicate in such a wealth of information, emotion, and ideas to others. Of course we are plastic in the sense that we learn the language of our childhood environment (I’m not writing this in Japanese, after all), but our ability to internalize grammar emerges from our biological make-up, which we do not choose. (Pinker, who studied in the M.I.T. linguistics department under Chomsky, uses this example among others to emphasize his point.)

Pinker delineates and actively patrols the fine line separating gender distinction from gender discrimination, and for that reason, his debate with Spelke is worth reading or listening to.

Albert Einstein

“Einstein immigrated to the United States in 1933, where he held a professorship at Princeton University until his retirement in 1945. His routine there was simple. Between 9:00 and 10:00 A.M. he ate breakfast and perused the daily papers. At about 10:30 he left for his Princeton office, walking when the weather was nice; otherwise, a station wagon from the university would pick him up. He worked until 1:00, then returned home for a 1:30 lunch, a nap, and a cup of tea. The rest of the afternoon was spent at home, continuing his work, seeing visitors, and dealing with the correspondence that his secretary had sorted earlier in the day. Supper was at 6:30, followed by more work and more letters.

Despite his humble lifestyle, Einstein was a celebrity in Princeton, famous not only for his scientific accomplishments but also for his absentmindedness and disheveled appearance. (Einstein wore his hair long to avoid visits to the barber and eschewed socks and suspenders, which he considered unnecessary.) Walking to and from work, he was often waylaid by locals who wanted to meet the great physicist. A colleague remembered, ‘Einstein would pose with the waylayer’s wife, children, or grandchildren as desired and exchange a few good-humored words.

Then he would go on, shaking his head, saying: ‘Well, the old elephant has gone through his tricks again.’ ”
