John Marks says yes - and he and the organization he founded, Search for Common Ground, have made it happen. He tells us surprising stories about how they get people to listen to each other, across hard lines of hatred and suspicion: Russian and American intelligence officers, Iranians and Americans, Israelis and Arabs, Hutus and Tutsis in Africa - and more. John's memoir, From Vision to Action: Remaking the World Through Social Entrepreneurship, is like a how-to guide - filled with candid accounts of his successes and failures.

Scientist Michelle Fournet and her colleagues from the University of New Hampshire hang out with humpback whales in Alaska, recording their daily communications - and then sending whale recordings back to the giant animals to see if and how they respond. Some of her latest findings could break new ground: she can identify individual whales by their sounds. Michelle tells us the moving story of how she morphed from broke actor to internationally-respected whale researcher - and how she hopes research on humpbacks' "language" can help humans protect them.

Four more have been murdered by a teen with an assault-style rifle - many more were injured - at Apalachee High School in Winder, GA. Still, this episode gives us a glimmer of hope: specialists in “behavioral threat assessment” have been quietly trying to spot potential killers for decades, in places from schools and companies to government agencies - and the latest carnage could probably have been avoided if authorities had followed their manual. Our guests, practitioners Monique Boudreaux and Matt Talbot, say everybody in America needs to help them instead of looking the other way.

Lee Bollinger, who was president of Columbia University and the University of Michigan, predicts that the number of black students at many colleges will plummet to low levels they haven't seen since the 60s and 70s. He says Chief Justice John Roberts and the other Republican extremists on the Court misinterpret the Constitution. And as for the belief that under affirmative action, college officials generally admitted blacks who weren't qualified? Lee says: Not true.

Trump, the Republican party and Project 2025 are echoing Orbán's autocratic playbook - along with strategies of other leaders who got elected democratically and then turned their nations into autocracies. Key steps: pack courts and agencies with their cronies, slander and intimidate the media, and denigrate their opponents as "evil" and "vermin." Harvard professor Steven Levitsky, co-author of How Democracies Die and Tyranny of the Minority, tells us why it could take years to rescue America's democracy - even if Trump loses the upcoming election.

Sesame Street changed TV by using music to help kids learn how to spell and how to share. Singer-songwriter Anya Rose and the group Ants on a Log write social action songs to help children in primary school learn edgier lessons, about problems from environmental pollution to racist and sexist behavior - inspired in part by 60s satirist Tom Lehrer. After hearing these tunes, the 9-year-olds in your family might feel inspired to research a problem in your own neighborhood - and then write your members of Congress about it!

Now that Judge David S. Tatel has retired from the U.S. Court of Appeals for the D.C. Circuit, he feels freer to warn us all: the Supreme Court is threatening America's democracy by inventing spurious legal doctrines and grabbing more power for itself. There are also lighter moments in this revealing interview, as David pulls the curtain aside and tells us how the judges on this powerful court really do their work. Spoiler alert #1: It used to involve a red children's sand pail. Spoiler alert #2: Because David is blind, he used to hire "readers" who rattled off every word of laws, books and briefs out loud to him, at such mind-boggling speeds that most people couldn't understand them.

David Tatel - who retired recently from the U.S. Court of Appeals - has led what he calls a "braided life" that intertwines hardship and accomplishment. With his wife, Edie, he describes how he struggled to hide his gradual loss of sight from friends and colleagues alike - including tricks like counting rows and seats in a movie theater and following the clicks of high heels. Meanwhile, David became an accomplished lawyer who fought landmark civil rights cases. You can read their full story in David's new book, Vision: A Memoir of Blindness and Justice. David will return in Part 2 to take us behind the scenes of the second most important court in the nation.
