Riley and Christopher and guest, Travis Patten, go all the way back to Classical Antiquity to explore contemplation from the incubation practices of Presocratic philosophers Parmenides and Empedocles—something like today’s sensory deprivation tanks—to the influence of the Late Antique philosopher Plotinus on the mystical traditions of Judaism, Christianity, and Islam.
