Brilliant men always betray their wives

The great philosopher Bertrand Russell, who for all his undeniable intellectual brilliance could never have bedded a woman on looks alone, was described as suffering from ”galloping satyriasis”. He claimed he could not see a sexual partner as sexually attractive for more than a few years, after which he had to make a new conquest.  He had affairs with a long line of women, a few of whom he later married. They included a young secretary, an MP’s wife, the daughter of a Chicago surgeon, a researcher, an actress, a suffragette, several teachers, the wife of a Cambridge lecturer and his children’s governess.

His private life was described by one biographer as ”a chaos of serious affairs, secret trysts and emotional tightrope acts that constantly threatened… ruinous scandal”. This was risk-taking of the highest order.
