What is the relationship between our minds and our brains? This familiar question raises a further one: what is the relationship beteween knoweldge of our minds, the kind we access through introspection, and knowledge of our brains, the territory of neuroscience. We seem to know a lot about our own minds, and most of us know next to nothing about our own brains. How can they be one in the same? And how can neuroscience reveal anything about philosophy of mind?

Patricia Churchland steps up in defense of materialism, and advocates for neuroscience's place in philosophy. She cites evidence to show that our intuitions about our own minds aren't as robust as we think they are, and suggests that they're probably closer to evolutionarily adapted coping-mechanisms than they are to actual knowledge. "The mind," she says, "is something that the brain does," and all phenomena of the mind can be reduced to activity in the brain. Ken asks, if this is true, then as we continue to discover neuorological explanations for mental phenomena, our concepts, both of these phenomena and of the mind itself, might adapt to accomodate them. Patricia thinks this is plausible, and points to monogamy as an example of a concept that recent research could throw into flux.
But before someone reforms his concepts to fit neurological explanations, he must first accept the explanations, and Patricia's theory is far from uncontroversial.

After presenting her view, Patricia goes on to respond to many challenges and objections from the hosts and from many callers. John points out that our faulty intuitions about our minds are among the mental phenomena neuroscience has to explain. Ken and callers give voice to the objection from subjectivity: mental facts are only knowable subjectively, through introspection, and the objective facts of a science cannot hope to capture them.
