Hello, Mr Singer, first may I say one of the most compelling books that I've read in recent yrs was your work about your grandfather who was a contemporary of Freud and who perished in a concentration camp. http://www.amazon.com/Pushing-Time-Away-Grandfather-Tragedy/dp/0060501316 (wonderful book, for those who haven't read it) How do you think your grandfather's story colours your world view? Do you think your aversion to unkindness comes directly out of learning about the horrors he lived through?Thank you for the book and for trying to be a force of good in the world.
