I know that from the days of Watergate... the notion of two sources on a story has become the popular dogma about how you confirm something. And there is a lot of truth to that, but there are all kinds of ways to check to the extent that you can, a story that you get.
What we are only now beginning to fully realize is that in seeking material pleasure too constantly, the capacity for enjoyment or fulfillment decreases and eventually becomes exhausted.
