Philosopher and author of Animal Liberation, which argues on behalf of animals’ rights on the grounds that principles of human equality should logically extend to animals. Michael Pollan takes the book to a steakhouse and reads it while eating meat and considering the ethics of meat-eating. Pollan finds Singer’s argument to be very strong, and he temporarily becomes vegetarian while he considers this question. He exchanges emails with Singer about the possibilities of eating ethically raised and killed animals, which Singer doubts. Pollan decides that he needs to learn more by taking a closer look at the details of slaughter.
