The Boston Globe runs a long article by Drake Bennett on sociobiologist Robert Trivers, who was one of the world's most brilliant thinkers from 1970-1975, but has been mostly AWOL for the last 30 years. Now, he's feeling smart again and promises lots of hot new ideas.
What the article fails to mention is why Trivers' career has been so erratic: manic-depression. Edward O. Wilson wrote in his fine autobiography Naturalist:
Trivers both benefited and suffered from a case of manic-depressive syndrome (now cured). When he was up he was dazzling, when he was down he was terrifying.
