Summary: For the past two decades, Reza Aslan has been studying religions from all over the globe, and talking to people who believe in one God, many Gods, or no God at all. He joins us this week to explain the origins of belief, why faith is ultimately a good thing for society, and how he got fired from CNN for calling Donald Trump a “piece of s**t.” (A spokesperson for CNN declined to comment on Aslan’s depiction of his dismissal.)
