Let me tell you about the history at the University of Sussex, which I greatly regret. When we started, in 1965, it was agreed that every science student should have to do at least one course taught by a faculty in the arts, and every art student should have to take some course taught by a faculty in the sciences. And when we opened biology, as part of this, we offered a course in human genetics, which was taught entirely by seminar. And the people in... on the arts side strongly recommended all the social psychologists and sociologists to enrol for this seminar course. And about six or seven of us, sort of... on the biology school, each took a seminar of some 10 or so students. And I think it was thoroughly successful. And the students liked it, and they learned all sorts of things about genetics that they wouldn't otherwise have learnt. And then I was just told that the sociology and the arts side had decided they no longer wanted their students to go to this course. And I said, 'Why not?' And they said, 'Well, genetics simply isn't relevant.' And it stopped. It wasn't our decision to stop it, it wasn't the students' decision they didn't want to go, it was just that the sociologists at the university decided that genetics was simply not relevant to their students. I think it's disgraceful, but that's what happened.
