David Deutsch, a philosopher and theoretical physicist, joins Peter Boghossian and Reid Nicewonder, President of Street Epistemology International, for a thought-provoking discussion. They explore the contagious nature of ideologies, particularly how social justice narratives affect open discourse and peer-reviewed literature. Delving into the Fermi Paradox, they question why we haven't discovered extraterrestrial life. The trio underscores the need for reason, courage, and critical thinking in navigating ideological conflicts and fostering meaningful dialogue.
