2 kinds of knowledge: 1. The kind that you can use to make testable predictions. 2. The kind that you can't use to make testable predictions. Kind 1 is easy to verify.

Some other people hold Kind 2 close to their heart and find rich meaning in it. With Kind 2, though, there's no good way to tell what's right.
