Summary of: Brain-Wise: Studies in Neurophilosophy
By: Patricia S. Churchland


Step into the captivating world of neurophilosophy with Patricia S. Churchland’s Brain-Wise: Studies in Neurophilosophy, a book that explores the intersection of neuroscience and philosophy. Delve into thought-provoking discussions on the existence of the immaterial mind or soul, the nature of the self, and the impact of neuroscience on our understanding of cognition, consciousness, memory, and reason. This comprehensive summary will introduce you to the awe-inspiring discoveries that profoundly challenge traditional views on metaphysics and the existence of God.

The End of the Immortal Soul

The book challenges doctrines that claim that people have immortal souls or minds that can freely choose by presenting scientific evidence that the brain handles every function that people used to attribute to the mind, including cognitive and mental activities. The book identifies the implications of these discoveries to philosophy, with particular attention to the intersection of neuroscience and philosophy. While it used to be impossible to blend natural philosophy with moral philosophy because of the soul’s supernatural dimensions, neurophilosophy is renewing the possibility of uniting these two fields. Finally, the book examines possible ways of reducing consciousness, cognition, and reasoning to neural interactions while addressing unanswered questions as well as the challenges associated with bridging the gap between neuroscience and cognitive science/ psychology.

The Evolution of Metaphysics and Biology

Aristotle’s Metaphysics aimed to explain the unobservable, fundamental existence of reality and the independent existence of mathematical truth. However, over time, physics, geology, and biology have answered some of those metaphysical questions. Evolutionary biology, for instance, offers the mandate of improved survival capability as an explanation for the functions and characteristics of organisms in its own terms. Biology challenges some widely-held ideas about the existence of the mind and soul and the nature of personality. As brain science investigates the brain’s phenomena, it has the potential to explain some of metaphysics’ most challenging questions.

Understanding Causality

Causes in the universe manifest in three ways and are often mistaken for correlation. While causality is still not fully understood, science has identified numerous correlations in the brain and is working to determine whether they are causal or not.

In “Understanding Causality,” the author explores the various ways in which causes manifest in the world, including precipitating, predisposing, and sustaining factors. Despite the prevalence of causality all around us, people often mistake it for correlation, as was the case with stress and bad diet being thought of as causes of ulcers for many years before bacteria was discovered to be the actual cause.

The concept of causality has been a topic of philosophical debate for centuries. David Hume argued that it was a fiction created to explain relationships that could not be explained by cause and effect. Nonetheless, causality remains a significant factor in brain science. While many correlations have been identified in the brain, scientists are still working to determine whether they are causal or just a coincidence. However, it is widely accepted that the brain is a “causal machine,” meaning that everything that happens in the brain has a cause.
