I bought this book for my Kindle because I was having a hard time deciding what book to download and read next. And surprisingly, it applies to atheism! Doesn't everything apply to atheism?
So, skipping to something of more universal interest, there's a chapter on moral decisions which of course refers to religious prescriptions, but also points out that the interpersonal parts of the 10 Commandments specifies not doing harm to others. I never made that connection before, perhaps because so much of O.T. interpretation got rewritten by people who didn't want us to touch ourselves. We've all heard the contradictory self-congratulatory versions of what the 10 Commandments are supposed to mean: 1) If not for those we'd be raping, stealing, and telling lies and generally running amok. If some Christians are actually sociopaths who need to be told these things and then actually restrain themselves... hahaha who am I kidding? That "explanation" is total bullshit. 2) says that there is a universal morality given to us by Gawd. This #2 explanation is the neo-apologists' way of accommodating evolution and multi-cultural perspectives. The secular #3 is more like that but without the Gawd crap, and this book basically says that. They make the point that getting along in society is the reason for rules like the non-theological commandments. (Well, of the Big 10 -- doesn't say anything about the other 600+ commandments in the OT)
