Dear Anna, we will live in a home with no walls, so that everywhere we go will be our home.

I started inventing things, and then I couldn't stop, like beavers, which I know about. People think they cut down trees so they can build dams, but in reality it's because their teeth never stop growing, and if they didn't constantly file them down by cutting through all of those trees, their teeth would start to grow into their own faces, which would kill them. That's how my brain was.

However much we obfuscate or ignore it, we know that the factory farm is inhumane in the deepest sense of the word. And we know that there is something that matters in a deep way about the lives we create for the living beings most within our power. Our response to the factory farm is ultimately a test of how we respond to the powerless, to the most distant, to the voiceless--it is a test of how we act when no one is forcing us to act one way or another.

There's nothing good about being certain about things. And I don't think there's any real talent in using language in a manipulative way, with phrases like "tax relief" or "Social Security reform." It's politically clever, but it's also completely disingenuous, and it's not something to aspire to.

Just to be a functioning adult in the world, we develop all of these layers of protection. When we see homeless people, we don't cry, even though homeless people probably deserve our tears - you know, it's a horrible thing.

Few people sufficiently appreciate the colossal task of feeding a world of billions of omnivores who demand meat with their potatoes.

We can't plead ignorance, only indifference. Those alive today are the generations that came to know better. We have the burden and the opportunity of living in the moment when the critique of factory farming broke into the popular consciousness. We are the ones of whom it will be fairly asked, What did you do when you learned the truth about eating animals?
