Our brains tell us that our intellects make us superior to animals.

The great divide in politics is all around us. Sometimes the best way to engage in a difference of opinion is to 'pass it by.' Political theorist Shalini Satkunanandan suggests we take that lesson from Friedrich Nietzsche's philosophy. Yeah, that guy — the one most known for his wrestling with nihilism. Satkunanandan argues that the constant need to engage and correct, refute or criticize "is making partisan divides even more pronounced." She views Nietzsche's method as a valuable way to navigate the highly polarized discourse of today. *This episode originally aired on Jan. 20, 2025.
