Today we are taking all the things we have learned this year about doing philosophy and applying that to moral considerations regarding non-human animals. We’ll explore what philosophers like Peter Singer and Carl Cohen have to say about their use, including the concept of equal consideration of interests.

In which John Green teaches you about the United States in the 1920s. They were known as the roaring 20s, but not because there were lions running around everywhere. In the 1920s, America's economy was booming, and all kinds of social changes were in progress. Hollywood, flappers, jazz, there was all kinds of stuff going on in the 20s. But as usual with Crash Course, things were about to take a turn for the worse. John will teach you about the Charleston, the many Republican presidents of the 1920s, laissez-faire capitalism, jazz, consumer credit, the resurgent Klan, and all kinds of other stuff.

Clint Smith teaches you about one of the most famous writers, orators, and advocates of the 19th century, Frederick Douglass. Douglass was born in slavery, escaped to the North, and became one of the most influential people of his time. Douglass wrote about the experience of slavery in a way that captured the attention of people throughout the world, and his work and influence helped directly in the struggle to abolish slavery and achieve emancipation.

In which John Green teaches you about the changes wrought by contact between the Old World and the New. John does this by exploring the totally awesome history book "The Columbian Exchange" by Alfred Crosby, Jr. After Columbus "discovered" the Americas, European conquerors, traders, and settlers brought all manner of changes to the formerly isolated continents. Disease and invasive plant and animal species remade the New World, usually in negative ways. While native people, plants, and animals were being displaced in the Americas, the rest of the world was benefitting from American imports, especially foods like maize, tomatoes, potatoes, pineapple, blueberries, sweet potatoes, and manioc. Was the Columbian Exchange a net positive? It's debatable. So debate.

When we talk about the American Revolution and Revolutionary War, the discussion often involves lofty ideals like liberty, freedom, and justice. The Declaration of Independence even opens with the idea that "all men are created equal." But it turns out, the war wasn't being fought on behalf of "all men." The war was mainly about freedom for white colonists, and liberty, justice, and the pursuit of happiness didn't apply to the Black people living in the British colonies. During the war, Black people took up arms on both sides of the conflict, and today we're going to learn how and why they participated.

The Art Assignment visits artist collective Dignicraft during their residency at the McColl Center for Art + Innovation, in Charlotte, North Carolina. Omar Foglio, José Luis Figueroa, and Paola Rodriguez give us the assignment to facilitate an Encounter / Encuentro, a form of community building.

Sarah Green then explores social practice with the work of Nicolas Bourriaud, who suggests that the rise of urbanization after World War II gave raise to art that is also urbanized.

INSTRUCTIONS - Encounters / Encuentros
1. Think of two people who you know who have similar interests but don't know each other
2. Facilitate a collaboration by introducing them and suggesting they do something together
3. Document the experience
4. Upload to your social media platform of choice using #theartassignment
5. Fame and glory (your work might be featured in a future episode)

A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he said that, for poets do not write to be understood. But it is true that if we look in glass of wine closely enough we see the entire universe There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflections in the glass, and our imagination adds the atoms. The glass is a distillation of the earth's rocks, and in its composition we see the secrets of the universe's age, and the evolution of the stars. What strange array of chemicals are in the wine? How did they come to be? There are the ferments, the enzymes, the substrates, and the products. There in wine is found the great generalization: all life is fermentation. Nobody can discover the chemistry of wine without discovering the cause of much disease. How vivid is the claret, pressing its existence into the consciousness that watches it!

If in our small minds, for some convenience, divide this glass of wine, this universe, into parts - physics, biology, geology, astronomy, psychology, and so on - remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let us give one more final pleasure: drink it and forget it all!
