Claim. The cosmos consists of two substantial realms: the incorporeal (spirit) world and the corporeal (physical) world, corresponding to mind and body in a human being. Both are real. The spirit world stands as subject partner to the physical world, which is “like a shadow” of the spiritual.
Elaboration. Per 6.1. The Incorporeal World and the Corporeal World as Substantial Realities: “The universe was created after the pattern of a human being, who is in the image of God’s dual characteristics. Therefore, the structure of the universe and every entity in it resembles that of a human being, which consists most fundamentally of mind and body. Corresponding to the human mind and body, the universe consists of the incorporeal world and the corporeal world, both of which are real and substantial.”
The phenomenology: the incorporeal world is perceived through “five spiritual senses.” Those with spiritual experiences “testify that the incorporeal world appears as real as the world in which we live.”
The relation: “The incorporeal world, or spirit world, is in the position of subject partner, and the corporeal world… is in the position of object partner. The latter is like a shadow of the former” (ibid). Both are substantial — DP is not Platonist — but the spiritual is causally and ontologically prior.
Death-transition follows directly: “When we shed our physical bodies after our life in the physical world, we enter the spirit world as spirits and live there for eternity.” The spirit-world is not a postulate of faith but a substantial reality humans pass into. DP rejects scientific materialism not by denying the physical but by asserting its derivativeness.
