Academia seems to have gone sex mad, the Diary notes. Last week, Wendy Doniger, professor of the history of religions at the University of Chicago, had an egg thrown at her for linking Hinduism and sex. Earlier this week, Olivia Judson of Imperial College London delivered her lecture on the evolution of female promiscuity. And next week Manchester University will launch a Centre for the Study of Sexuality and Culture. It promises "stimulating intellectual exchange" including an opening address on the "20th-century orgasm".~
