When there's no vaccine on the market, people will look for other ways to be safe, including school closures and the handwashing of groceries.

While operating on a 16-year-old girl who suffered from severe seizures, neurosurgeon Itzhak Fried stumbled on the region of the brain that makes us laugh. To neuroscientist Patrick House, Fried's ability to produce laughter surgically raises deep and disconcerting questions about how the brain works. Join Fried, House, and EconTalk's Russ Roberts for a live broadcast from Jerusalem's Shalem College that is a sequel of sorts to House's earlier appearance on EconTalk. House and Fried discuss the mystery of consciousness and try to square the biological bases for emotions with the circle of our humanity.

Is the perfect really the enemy of the good? Or is it the other way around? In 2008, Duke University economist Michael Munger ran for governor and proposed increasing school choice through vouchers for the state's poorest counties. But some lovers of liberty argued that it's better to fight for eliminating public schools instead of trying to improve them. Munger realized his fellow free-marketers come in two flavors: directionalists--who take our political realities as given and try to move outcomes closer to the ideal--and destinationists--who want no compromises with what they see as the perfect outcome. Listen as Munger talks to EconTalk's Russ Roberts about two different strategies for achieving political goals. Along the way, they discuss rent control, the minimum wage, and why free-market policies are so rare.

When he was a child, poet Dana Gioia's mother would come home from a long day of work and recite poems while she cleaned. It was a way, he realized later, for her to express the feelings she didn't want to describe directly, and to vent her sorrows without burdening her son. This, he believes, is what makes poetry so compelling: It's the secret language of emotions, a bit of magic that gets us through the day. Listen as Gioia speaks with EconTalk's Russ Roberts about poems, mortality, and loved ones who died too young. Gioia also explains the fundamental role of allusions in poems, and how--if they’re really good--they have the power to summon the dead.

They operate according to rules we can never fully understand. They can be unreliable, uncontrollable, and misaligned with human values. They're fast becoming as intelligent as humans--and they're exclusively in the hands of profit-seeking tech companies. "They," of course, are the latest versions of AI, which herald, according to neuroscientist and writer Erik Hoel, a species-level threat to humanity. Listen as he tells EconTalk's Russ Roberts why we need to treat AI as an existential threat.
