Christopher Rouchhio, bestselling author of the Sun-Eater series, joins Josh to discuss C.S. Lewis's book The Abolition of Man. Roucchio structures his Kingdoms of Death around Lewis's different anthropological categories, and that beginning sets up a conversation about science fiction, human nature, knowledge, and the benefits of limits for human nature. Along the way, they discuss Lewis's Innovators, conditioners, and argument about transhumanism.
