Rather, I will move toward a moral theory that is highly coherent with what is known about how
brains make moral decisions, and with other psychological and social facts. This moral theory should
be a central part of a general account of wisdom and why life is worth living. As in chapter 8, the
crucial bridge between is and ought is provided by human needs that point to a general theory of what
makes actions right and wrong. I will discuss brain mechanisms such as mirror neurons that enable
and encourage people to care about others as well as themselves.
