This week we talk to philosopher and animal ethicist David Pe\xf1a-Guzm\xe1n about his new book When Animals Dream: The Hidden World of Animal Consciousness. David explores the idea that there really is a subjective world\u2014a dream world\u2014that lights up when animals sleep, what that actually looks like, and its moral implications.Support the show: https://www.patreon.com/inquiringminds
