Mommy Dark, you said:
It's much harder to find an ethical baseline, a moral imperative, without buying one of the shrink-wrapped, tidy, but often hate-filled salvation packages offered by Churchianity.
Actually, we all have a natural inclination to discern the good from the bad, even if we're atheists. This is because the fundamental ethical principles are products of biological evolution, not culture. Michael Ruse makes this point in his book "Taking Darwin seriously: a naturalistic approach to philosophy", which is highly recommendable for anyone interested on the scientific foundations of ethical behavior.
