We are revisiting a conversation Tom had in February 2015 with David Linden, a neuroscientist at the Johns Hopkins School of Medicine, and the former editor of the Journal of Neurophysiology. His first book, The Accidental Mind, explored how our brains evolved over time to make us capable of things like romantic love and belief in God. In his second, called The Compass of Pleasure, he argues that we are hard-wired to seek pleasure in a variety of forms. In both works, he writes about the complex links between our minds and our bodies. Last year, he published a book in which he takes up the subject of touch, and again, he proposes that the many ways in which we experience touch, from a tender caress to a painful injury, are tied, in one way or another, to our emotions. The book is called Touch: The Science of Hand, Heart and Mind. It’s just out in paperback. David Linden will be talking about the book at the Barnes and Noble Bookstore in Charles Village tomorrow night.
