``The ultimate model of an activity that is at once unquestionably intelligent and intellectual and that also seems to divide the sexes is mathematics. The maleness of a mathematics department is explained either in terms of an allegedly greater male ability in mathematics, or in terms of sex-role steereotyping. You know the sort of things: ``As boys learn their sex roles, they identify with the notion that they should excel in mathematics. Girls ... learn that mathematical ability is unfeminine,'' in the words of Diane F. Halpern's _Sex Differences in Cognitive Abilities_. (But the logician Ruth Marcus reports that there are feminists who argue that logic and physics are ``phallic,'' and that therefore women who go into those fields sell out, or buy out, or something. They used to be unfeminine, now they are unfeminist.) ``MIT mathematician Gian-Carlo Rota said to me one time that he thought both positions were ridiculous. ``There are plenty of women with all the talent for math anyone could want,'' he said. ``But women leave math when they discover that you can't do it without sustaining world-class illusions, such as the belief that grips one while one is working on a very difficult paper on a very obscure corner of a difficult subject, that here, at last, everything will be settled once and for all.'' Interestingly, he doesn't talk about the desire to excel, at math or anything else, as the point - he doesn't mention competitiveness. ``..Rota identifies the illusions necessary to mathematics with the faith that sustains a friend of his who is a priest. Women refuse such illusions or, say, don't care about them, are able to remain relatively calm in the face of the fact that there are issues that won't be settled once and for all, such as the exact nature of the universe or exactly what Daffodil means when she cocks her head and sticks her tongue out at you. I do not mean that women working with animals are satisfied with oversimplified or partial theories of animals, only that their minds are complex enough to sustain their contact with what they do know while noting also where their knowledge of Daffodil leaves off'' ``...I keep thinking: Men are afraid of horses. They are afraid of horses because neither their professional integrity nor logic will take them to a horse, and because they do not know how to turn, deflect, a horse's fear or rage. If Dobbin says, ``You'd better get off right now, because I am going to kill you, wrangler!'' you don't of course ignore this, but it is possible to say, ``Oh, I don't think you really want to do that. Why don't we try something else?'' (Just as Moses' wife said to Yahweh when Yahweh was intent on killing Moses.) As it happens, a talented young male rider can be as formidably equipped with equestrian tact as anyone, but in the general run of things in the middle and upper classes in this country, it is the young women who are more likely than the young men to come up with a tactful rather than frightened response, and when they become foolish about this later - silliness is a feminine failing - they will say that they knew the horse had good intentions all along. ``For centuries, unable to prove Dobbin's good intentions, men have instead proven their courage on horseback...''
