Schur’s gift to the reader is his ability to distill the writing of ancient philosophers such as Aristotle and Socrates, more recent ones such as John Stuart Mill and Jeremy Bentham, and modern thinkers such as Pamela Hieronymi and Peter Singer into breezy, engrossing chapters. It’s as if the author has his arm around your shoulder and is whispering in your ear, Come on, give it a go; this is going to be fun. It’s a lively romp through moral philosophy that’s not dumbed down to be the philosophical equivalent of the chicken dance.
