This is a wake-up call. The popular epistemology has been flaming garbage for so long. When you see something for yourself, that delivers one kind of knowledge. When you hear it from a friend, that delivers another kind of knowledge. When you hear it from somebody you don't know, and never actually met, second or third hand, that delivers yet another kind of knowledge. And, in our society, that last kind of knowledge is so often treated as equivalent to the first. Which is messed up.
