"Knowledge-like the sky- is never private property. No teacher has a right to withhold it from anyone who asks for it. Teaching is the art of sharing."

The whole problem with the world today: private property. If no one owned anything, it would be a lot better. There's even an entire industry devoted to keeping an eye on other people's stuff. This is how stupid it's got. If you decide to get rid of a lot of your stuff, you can give it to a thrift shop or to Goodwill.
