Episode 53 of the Brain Science Podcast is a discussion of Did My Neurons Make Me Do It?: Philosophical and Neurobiological Perspectives on Moral Responsibility and Free Will by Nancey Murphy and Warren S. Brown. This book challenges the widespread fear that neuroscience is revealing an explanation of the human mind that concludes that moral responsibility and free will are illusions created by our brains. Instead the authors argue that the problem is the assumption that a physicalist/materialistic model of the mind must also be reductionist (a viewpoint that all causes are bottom-up). In this podcast I discuss their arguments against causal reductionism and for a dynamic systems model. We also discuss why we need to avoid brain-body dualism and recognize that our mind is more than just what our brain does. The key to preserving our intuitive sense of our selves as free agents capable of reason, moral responsibility, and free will is that the dynamic systems approach allows top-down causation, without resorting to any supernatural causes or breaking any of the know laws of the physical universe. This is a complex topic, but I present a concise overview of the book’s key ideas.

Ginger Campbell, M.D., is an emergency physician whose long-standing interest in philosophy and science motivated her to begin podcasting in 2006. While her Brain Science Podcast focuses on neuroscience, her other show, Books and Ideas, often explores the intersection between science and religion. She is also the founder of sciencepodcasters.org, which is a site devoted to promoting science through podcasting.
In this conversation with D.J. Grothe, Ginger Campbell recounts how she first got involved in science podcasting, and why she focuses on neuroscience as her topic. She discusses the impact of Jennifer Michael Hecht’s work on both her intellectual pursuits and her views about atheism and religion. She talks about the trends in neuroscience that may suggest the brain can be "trained" with products such as Brain Age on Nintendo’s DS Lite, or that one’s diet can increase one’s intelligence. She describes "neuroplasticity," and how new brain imaging technologies, such as advanced fMRIs, show that our daily actions can impact specific parts of the brain. She explores the implications of neuroscience for religious belief, and why she has at times resisted the idea of atheism. She shares her reactions to the "New Atheists." And she discusses the increasing attacks on neuroscience from Creationist activists because of what it implies about consciousness, free-will and the existence of the soul.
