The famous street artist Banksy shocked the art world in 2018 when his painting, Girl with Balloon, partially shredded itself moments after selling it for over a million dollars. at a Sotheby's auction in London. Banksy had secretly built a mechanical shredder into the painting's ornate frame, turning the destruction into a piece of performance art which was later authenticated and renamed Love Is in the Bin. He did this to make a statement about the art market's hyper-commercialization.

One of the most famous and influential philosophers of the ancient world enjoyed doing similar types of shocking stunts to make his point in the most memorable way possible. Diogenes the Cynic had a reputation for eccentricity. He lived in a large clay wine jar and owned almost nothing, a demonstration that true freedom and happiness come from self-sufficiency. He defecated in public, and when criticized, he asked why it was acceptable to eat there but not to perform other natural acts, illustrating that social shame is arbitrary and not rooted in nature or reason.

Since his death in 323 BC, devoted followers made him and his ideas famous the world over. But some modern philosophers like Friedrich Hegel thought of him as just a shock jock. To him, Diogenes had a way of life based on simple, isolated maxims and provocative anecdotes—like those of a folk figure—rather than a fully developed, systematic philosophical system that truly captured the evolving spirit of reason in history.

Today’s guest is Inger Kuin, author of “Diogenes: The Rebellious Life and Revolutionary Philosophy of the Original Cynic.“ We look at this iconoclastic philosopher whose brash and free-thinking vision of life ended up inspiring the philosophy of Stoicism. His philosophy stresses the importance of living here and now and not concerning ourselves with things out of our control. Diogenes also stands apart as history’s first recorded critic of slavery, a lone voice of his time that powerfully influenced future thinkers, from Epictetus to future abolitionists.

The greatest energy source for civilization before the steam engine was wind. It powered the global economy in the Age of Sail. Wind-powered sail ships made global shipping fast and cheap by harnessing free, reliable ocean winds to propel large cargo loads over vast distances without needing fuel or frequent stops. It also powered windmills, the factories of the Middle Ages and Renaissance. Windmills allowed for abundant bread by milling flour by turning heavy grindstones with wind-driven sails. They also powered trip hammers to forge iron and steel by lifting and dropping massive weights. We can credit them as well for pumped water, sawed timber, and processed oils, spices, and paper.

Wind is one of most elemental yet overlooked forces shaping our world today, and it is at the center of the human story. Many times it changed history – such as “Protestant Wind” saving England from the Spanish Armada, kamikaze winds halting the Mongol invasions of Japan, and easterlies carrying Chernobyl’s fallout. Wind also powers massive turbines today, but there was a forgotten moment in the 1880s when we could’ve chosen wind power over fossil fuels. It even creates certain types of civilizations. Some historians believe the cleverest and most civilized people lived in places where weather was varied and posed constant challenges.

Today’s guest is Simon Winchester, author of “The Breath of the Gods: The History and Future of the Wind.” We look at how wind—life‐giving and destructive, chaotic and harnessable — has shaped civilization from antiquity to today.

Maps have always had problems. Five hundred years ago, maps were wildly inaccurate simply because cartographers were drawing the edge of the known world, limited by slow ships and nonexistent satellite data, resulting in continents that were too large, too small, or entirely misplaced. All of those problems have been solved thanks to new technology, but now there are new ones. Even though we know the exact dimensions of Earth, our maps are still "wrong" because we force a three-dimensional globe onto a flat surface, leading to mathematical distortions like the Mercator projection, which wildly exaggerates the size of landmasses near the poles. One map that tries to correct the Mercator projection's distortion of landmass sizes is the Gall-Peters projection, but to achieve this size accuracy, it severely stretches and distorts shapes, particularly near the poles, making Alaska look like a whirlpool or expanding pinwheel.

To make it even more confusing, there are maps that were deliberately tweaked to hide government secrets or those drawn with junk data just to trick an enemy into giving up territory. But for today’s guests, Jay Foreman and Mark Cooper-Jones, they enjoy these sort of cartographic oddities. They are the authors of “This Way Up: When Maps Go Wrong and Why it Matters.” We discuss all sorts of maps that went wrong—from the infamous Mountains of Kong—a completely made-up mountain range that ran East-West across the entire African continent--to colonial maps with mathematically impossible borders and US states with fake cities. We also discuss

• The frequent omissions of New Zealand on maps that use the Mercator projection
• Maps that will land you in prison depending on which countries claim certain territories
• Cold War-era Soviet paranoia that falsified virtually all maps for decades on the direct orders of secret police
