The Transmigration of Timothy Archer

Philip K. Dick often merges speculative ideas with deep questions about existence. I wonder what influenced his approach here and how he balanced the two.

His struggles with belief and doubt felt very human, yet also layered with philosophical complexity. How did others interpret his spiritual evolution?

The idea of the soul moving beyond death added a mystical dimension. I'm curious whether this was more metaphorical or meant as a literal belief in the novel.
