Porosity Complicated

By: Rebecca McInroy

Last week’s episode focused on the concept of “porosity” a term developed by anthropologist Tanya Marie Luhrmann and psychology researcher Kara Weisman, to help understand the root of religious and spiritual beliefs. They argue that at the heart is the concept of a porous boundary between mind and world and that people in all human societies have conflicting intuitions about this boundary.

Here at Two Guys on Your Head, Dr. Art Markman,  Dr. Bob Duke, and Rebecca McInroy find this concept interesting and thought we would spend a little time, not only understanding it but complicating it.

In this second in our three-part series on porosity we ask a few questions about how it manifests in our daily lives and why we should care.

“Porosity is The Heart of Religion”
