In conversations with Christians (and members of other religious groups), more often than not I'm asked on what grounds atheism can claim to have an objective morality. This isn't a new question, but it is one I don't feel properly equipped to answer well. I think reason and our intuitions can aid us in finding objective moral truths, but I often find myself at a loss articulating a good defense. I do not find the theist's claim that morality depends on God's existence a good one, but I want to advance a better argument for why secular morality works out, and not just knock down their view. What's the general consensus among philosophers? Is there a firm foundation for morality without God?
