An Eye for an Eye

I ran across an account of an interview with Arun Gandhi, the grandson of Mahatma Gandhi. He quoted his grandfather as saying, "An eye for an eye only makes the whole world blind." I have often thought of the biblical presription of an eye for an eye. It has always seemed barbaric to me, at least taken literally. When I read the quote I had the fantasy of all of us walking around blindly bumping into everything and each other with little understanding. I would like to know what else Gandhi had to say on the subject.
