They never get beyond appearances, never reach an ultimate level of reality. In Dick’s late theological novels,46 there are signs and messages that may have come from a transcendent Beyond. But in most of the earlier books, we don’t even get that. And Dick is well aware, in any case, that signs and messages are always ambiguous, always subject to the vagaries of interpretation. This is why most readings of Dick have focused on issues of epistemology and hermeneutics. Dick is commonly said to be asking questions about what is real, what is authentically human, and how we can ever know for certain about such things.
