"That stealing from members of your own community is immoral requires no divine revelation. It is revealed by a moment's reflection on the type of society that would exist if everyone stole from one another. If lying were considered a virtue instead of truth-telling, communication would become impossible. Mothers have loved their children since before mammals walked the earth -- for obvious evolutionary reasons. The only precepts unique to religion are those telling us not to question their dogma."
