The value of human lives is linked to human potential, and our potential is surprisingly vast. We are involved in all sorts of valuable activities, which give our lives meaning. In addition, our understanding of these activities is always developing. We engage in continuing conversations about what it means to be a good artist, a good parent, a good executive. Because human potentialities are unfolding, we have an ongoing need to engage in moral reflection.

New ways of thinking can be liberating and inspiring, but they need to be melded with previous insights. Continual change forces us to engage in continual evaluation and re-evaluation. Fortunately, we are not set adrift on this sea of human potential without boat or sail or rudder. We can be highly confident of certain conclusions about living well. Some of Aristotle's basic ideas provide reliable guidance.
