In My Brain Made Me Do It: The Rise of Neuroscience and the Threat to Moral Responsibility (Prometheus Books, 2010), Eliezer J.

In The Brain and the Meaning of Life (Princeton University Press, 2010), philosopher and psychologist Paul Thagard discusses the reason we are wired to form social bonds: loving relationships can give a sense of purpose to our lives.
