A collection of essays on the intersection of theories of free will and ethics from a naturalistic (atheistic) perspective:
A sample, from one theorist intent on overcoming "free will panic":
"As rather sophisticated cognitive systems, we're very good at modeling the world, and any causal disconnection from the world would worsen, not improve, our ability to model it. Stepping outside of determinism, an impossibility, can't give us a more correct view of things. Any part of us outside the causal network, anything radically free to choose its words, would be uninfluenced by the world, and so this part couldn't know anything about the world. There's no conflict between being influenced or determined to have a view of the world and having a truer, more accurate view of it."
