Shakespeare, as usual, was on to it. Beware, he said in Othello, of jealousy: "It is the green-ey'd monster which doth mock the meat it feeds on.
And who among us humans, male and female, has not felt that hot, twisting worm?" Buss argues that jealousy hasa purpose in our evolution as a species: "a crystalline logic, precise purpose and supreme sensibility".
His extensive research involving thousands of subjects in many countries reveals much about the untamed demons in our lives, and his book is a lively delight.
