In one of L. Neil Smith’s libertarian-ish sci-fi novels, I recall in he made a comment that to understand human action, it’s not either nature (genes), or nurture (environment), but rather it’s more like one-third nature, one-third nurture, and one-third free will (choice, volition). I loved it and have long remembered it, but now I can’t find it. If anyone knows where I can find this, please leave a comment below or email me.
