We all tend to forget that we are the law in the sense that we make the rules as a function of our current societal and personal values. As the rationale for our values and beliefs change, so too can the laws we choose to live by. Appreciating the mind/brain system as a downwardly causal system liberates one from a closed loop kind of determinism. Under closed loop determinism, the concept of personal responsibility becomes nonsensical. On the other hand, a downwardly causal system that responds to new information and discovery and that can learn social rules is adaptive. Moreover, since this downwardly causal system exists alongside billions of others, all of the ingredients for personal responsibility are present. The final lecture in a series of six Gifford Lectures by Professor Michael Gazzaniga. Recorded 22 October, 2009 at the Playfair Library Hall, the University of Edinburgh. Audio version.
