Tamler learns something new about menstruation. David weighs in on the democratic debates and the impeachment hearings. Then we map the various social and political factions onto the factions in our respective fields. Who are establishment neoliberals of philosophy, and who are the white feminists? What about the IDWs of psychology – and the Chads and Stacys?

Do the words we happen to use deceive us into thinking we have “carved nature at its joints”? What is a natural kind anyway when it comes to emotions?

Plus, after the outro, a quick unedited Mr. Robot discussion of the revelation in season 4, episode 7.
