In Marriage and Morals (1929), Bertrand Russell mentions that, while “[c]ruelty is in theory a perfectly adequate ground for divorce, … it may be interpreted so as to become absurd”:

When the most eminent of all film stars was divorced by his wife for cruelty, one of the counts in the proof of cruelty was that he used to bring home friends who talked about Kant.

I haven’t been able to figure out who this is. Russell writes, “I hardly suppose that it was the intention of the California legislators to enable any woman to divorce her husband on the ground that he was sometimes guilty of intelligent conversation in her presence.”
