How important are Boundaries?

Today, we take a more literal approach as we look to Trump's wall and the various meanings that can be derived from it. We ask what does it mean to have a wall, a fence, a limit to our physical and personal space?

Another driving question in today's episode is: Why do good fences make good neighbours? We will hear from Robert Frost directly but think about the resonance of that idea. Limitations to space, demarcations of a perimeter allow for the construction of an identity, be that of a farm, a garden, a room or indeed a person.
