The Ultimate Message of the Human Advantage

The ultimate message of the human advantage is why I finished with this critique of materialism, not just because it's at the base of this whole debate about technology. We need to do the best that we can to get rid of materialism at least as a public philosophy so that it's relegated to the private philosophies of a few cranks in their kitchens. That's exactly it. In order to be virtuous and act virtuously, we have to believe that we're free agents that are actually able to improve ourselves with effort and with habit. So what should people give me a couple of things people should read besides Human Advantage?
