June 1981
Using Transmigration as a starting point Dick brainstorms his next book. He envisions a spiritual journey along the lines of Dante’s Divine Comedy organized around an underlying structure of vertical space and a foreground of horizontal time.
Through spiritual insights his character will ascend a vertical axis he isn’t aware of, since it is hidden behind linear time. This character is stuck in Purgatorio in what Dick imagines as some kind of self-generated amusement park guided by a computer that plays the role of Dante’s Virgil leading him through the maze.
