This is a short discussion of only about 15 minutes.
These are not rules in the traditional sense of rules and you do not have to be a student in the traditional sense of being enrolled in a class. These "rules" are more guidelines for how to listen in a way that will maximize your ability to engage with difficult topics on which you might have pre-existing perspectives.
My classroom students really liked these rules.
Note: While I originally wrote these rules for the benefit of my students, I also wrote them to reflect my own experience and my own efforts to get beyond my assumptions about something difficult to understand.
