When tragedy strikes an individual, a nation, or an entire people, artists and architects are tasked with designing a public display that memorializes the event and its victims. But how do you do that? In this episode, art historian and podcaster Tamar Avishai examines the Denkmal Memorial to the Murdered Jews of Europe in Berlin, the Vietnam War Memorial in DC, and others to look at how respecting and remembering loss collides with the demands of history and politics. We look at why abstract rather than representational memorials resonate better with people in recent years, and whether memorials, no matter how well done, might lose their impact after a single generation. Guest voices include Karen Krolak, James Young, and Michael Hays.LinksListen to Tamar Avishai on The Lonely Palette podcastBetter Help-betterhelp.com/nation.

The first two gene-edited species meant to be introduced into the wild are currently in their final stages of approval, with trials already underway for the Oxitec mosquito, and the ESF American Chestnut. In this episode, we examine what these gene-edited species are, what they do, and how they are the beginnings of bio-engineering in the era of massive anthropocentric ecological change. We then look at the ethics of bioengineered wild species and whether they can be the solution to an imminent era of mass extinction. Guest voices include Chairman of the Florida Mosquito Control District Phil Goodman, ESF scientist Andrew Newhouse, and philosophers Evelyn Brister (RIT) and Ron Sandler (Northeastern).This episode sponsored by betterhelp.com/nation.

Barry invites Willa Paskin of Slate's Decoder Ring podcast to talk about their recent episode, The Alberta Rat War, as a set up to next week's Hi-Phi Nation episode on genetic engineering. We then proceed to that episode.Rats live wherever people live, with one exception: the Canadian province of Alberta. A rat sighting in Alberta is a major event that mobilizes the local government to identify and eliminate any hint of infestation. Rat sightings makes the local news. Alberta prides itself on being the world’s sole rat-free territory, but in order to achieve this feat, it had to go to war with the rat. On this episode of Decoder Ring, we recount the story of how Alberta won this war, through accidents of history and geography, advances in poison technology, interventionist government policy, mass education programs, rat patrols, killing zones, and more. The explanation tells us a lot about rats and a lot about humans, two species that are more alike than we like to think.Some of the voices you’ll hear in this episode include Karen Wickerson, rat and pest program specialist with Alberta Agriculture and Forestry; Robert Sullivan, author of Rats: Observations on the History & Habitat of the City’s Most Unwanted Inhabitants; Phil Merrill, former rat and pest specialist; George Colpitts, historian at the University of Calgary; and John Bourne, former manager of Alberta’s rat control program.Decoder Ring is a podcast about cracking cultural mysteries. Every episode, host Willa Paskin takes on a cultural question, object, idea, or habit and speaks with experts, historians, and obsessives to try and figure out where it comes from, what it means, and why it matters.

Penny Lane gave up months of wages and weeks of her life to have her kidney cut out and given to someone she never knew, and who may never thank her. She is one of about 200 people in the US a year who give up a kidney altruistically. What motivates someone to do that? Evolutionary psychologist Michael McCullough believes that not only is there true altruism amongst the human species, but that it is a unique trait, an emerging and spreading trait, and it is selected for by evolution, even out-competing the more familiar traits of selfishness that drive evolution in other species. And the trait is responsible for moral progress in the world. Barry is skeptical, and calls friend of the show Kieran Setiya to talk him out of his skepticism, only to discover that, in many ways, humans are even worse than he thought. We may have evolved to demand altruism from others, but not be altruistic ourselves.This episode brought you by Scribd and Inkl. Get an enormous library of books, magazines, podcasts, and audiobooks.

In 1968, David Lewis decides that one truth can unify every theory he's had about the nature of the universe. It is the truth that every possible world is equally real. Lewis not only argues for this view, but devises a distinctive way of arguing for it, a method of doing philosophy that is as influential as his views. Meanwhile, a soon-to-be colleague and rival, Saul Kripke, reads Lewis' paper and fires off eight objections, and on the other side of the world, an entire continent becomes enamored with the life and works of David Kellogg Lewis, an admiration that survives to this day. Guest voices include Frank Jackson, Alan Hajek, John Bigelow, Helen Beebe, Anthony Fischer, Peter Anstey, and David Lewis.This episode brought to you by Betterhelp, online therapy and counseling.

What was David Lewis like as a person? The consensus is that he did not know how to converse. At Swarthmore, David Lewis discovers he has a knack for philosophy and none at all with women, leading to a lifelong examination of the norms for conversation. By the time he reaches Harvard, he is ready to meet the love of his life, but almost fails out of the program in the process. By the end of his Harvard days, an entire continent on the other side of the Earth is abuzz about a rising star.

We accompany the story of his early life with his theory of time, time travel, and the self. Guest voices include R.

A woman spends 40 years in and out of prison for shoplifting and finally gets a break from a judge in her late 50s. She uses the opportunity to abolish a jail and transform her city. This week we look at prison abolition and the arguments for eliminating all punishment from the system. From the denial that we have free will, to the view that perpetuating injustice disqualifies the state from punishing, we look at whether any of us have the right to punish anyone else, and question the very purpose of the criminal justice system.Guest voices include Marilynn Winn, Gregg Caruso, Michael S. Moore, Erin Kelly, and Kimberly Kessler Ferzan.In Slate Plus, Barry speaks to Kimberly Kessler Ferzan about separating the criminal justice system into two distinct institutions, one dedicated to retributive punishment, and one dedicated to crime prevention. Why should there be two systems and what would be involved in separating them? Learn more about your ad choices. Visit megaphone.fm/adchoices
