Peter Singer on R. M. Hare

“I have mentioned three of Hare's achievements in moral philosophy: restoring reason to moral argument, distinguishing intuitive and critical levels of moral thinking, and pioneering the development of practical or applied ethics.”

“he [Hare] was never afraid to ask the most controversial questions, such as What is Wrong with Slavery? and his answers were always enlightening. (Indeed, that particular paper is one that he was able to write with an authority that few others could possess, since, as he notes, he had in a manner of speaking been a slave, when as a prisoner of the Japanese he worked on the Burma railway.)”
