In her brilliant work Touching a Nerve, Patricia S. Churchland, the distinguished founder of neurophilosophy, drew from scientific research on the brain to understand its philosophical and ethical implications for identity, consciousness, free will, and memory, according to a review published on goodreads.com.
In Conscience, she explores how moral systems arise from our physical selves in combination with environmental demands.
All social groups have ideals for behavior, even though ethics vary among different cultures and among individuals within each culture. In trying to understand why, Churchland brings together an understanding of the influences of nature and nurture.
She shows how children grow up in society to learn, through repetition and rewards, the norms, values, and behavior that their parents embrace.
Conscience delves into scientific studies, particularly the fascinating work on twins, to deepen our understanding of whether people have a predisposition to embrace specific ethical stands.
