Having read the full Sandman collection, American Gods, most of Neverwhere and Smoke and Mirrors, I find a common philosophical/religious overtone among them: that human belief directly shapes reality. Specifically American Gods and Sandman share this, where gods and the like are empowered and enabled by those humans who worship them (and are weak and world-weary when they are forgotten). I wonder, what is the basis for this worldview? What literature have you consumed to develop this conception? Do you personally hold this concept to be true?
