Filtering Free Speech
The line between free speech and hate speech isn't always clear. When college students shout down a campus speaker, when a woman yells racial slurs in a parking lot, or when HR calls with a reprimand — when does free speech violate safe space? When does sensitivity become censorship?
This weekend’s program "Filtering Free Speech" examines the difficult subject of censorship and free expression. In our first interview, acclaimed writer Walter Mosley uses the "N-word" four times to describe a very troubling experience when he was reprimanded for using this word in a Hollywood writers’ room. Mosley, who himself is black, was so angered by the exchange that he resigned from his job.
The "N-word" is intrinsic to his story — not gratuitous — so we have chosen not to bleep the word. On the broadcast our host provides a very clear warning to alert listeners to what they will hear.
If you'd prefer to listen to a censored version, you can listen to one here.

Who Owns Seeds?
It's easy to take seeds for granted, to assume that there will always be more corn or wheat or rice to plant. But as monocropping and agribusiness continue to dominate modern farming, are we losing genetic diversity, cultural history, and the nutritional value of our food? We speak to farmers, botanists and indigenous people about how they are reclaiming our seeds.

Finding Meaning in Desperate Times
We’ve all been changed by the experience of living through a pandemic. We figured out how to sanitize groceries, mute ourselves on Zoom and keep from killing our roommates. But we’re also tackling bigger, existential questions — how can we, individually and collectively, find meaning in the experience of this pandemic?

Our Virtual Reality
Not everyone has a nice, big yard to stretch out in while sheltering in place from COVID-19. But maybe you don't need one. People are using virtual spaces to live out the real experiences they miss — like coffee shops, road trips, even building your own house on a deserted island, or Walden Pond. In a world where we're mostly confined to our homes and Zoom screens, does the line between virtual and real-life space mean much anymore?

Writing Truth and Lies
We all tell stories about our lives: funny stories, happy stories, sad stories. But are they true stories? In an
age of “alternative facts” and “fake news,” we’re all thinking harder about why truth matters – not just in politics, but in our personal lives. A biographer, a poet, a memoirist and a filmmaker describe the moral struggle and personal cost involved in telling not just the truth, but the whole truth.
