Ever since the 18th century, when a French anatomist named Meinard Simon du Pui declared us “Homo duplex” due to our two-sided brains, we have understood that humans are “not one but two.” We are divided creatures balancing impulses ranging from the saintly to the bestial. As seekers, how do we bridge this gap between so-called higher and lower impulses? Are we meant to avoid our animal drives and instincts? Of course not. It’s a question of the Middle Way.
