down from the mountains today for four days off. the transition gets harder as the summer progresses. in honor, however, of the occasion, i post a sermon. still rivalling my father after all these years, i've given a few, though in the university context. (the subversive poet at work. a couple were on 'the anthropology of love', another in praise of vampires on halloween.) more standup comedy routines than lectures, i felt the audiences bewildered by my audacity. these notes for a talk on 'grid theory' don't really show the insanity of my approach, but at least you get the ideas. alas, i'm less sure of myself than in the past. the older i get the less i know. is that the way with all of us?
