We explore Paul Draper's "psychological aether theory" or "aetherism". In addition to gravitation, electromagnetism, and the strong and weak interactions, there is a fifth fundamental interaction: A field of consciousness, a world-soul or mental aether that interacts with our brains. 

"How does the brain produce the mind? It doesn't. Instead, mentality exists quite independently of the brain."

Draper's recent work on aetherism is a refinement of a view proposed by William James in his 1898 Ingersoll Lecture on Immortality. James doesn't deny that thought is a function of the brain. Rather, he challenges the assumption that the function in question is one of production. He defends what he calls the "transmissive function" view over the theory that thought is produced by the brain. For James, consciousness pre-exists, with our brain giving finite human shape to experience, like the pipes of an organ shape the trembling air as it escapes from the organ's air-chest. Aetherism can explain the tight correlation between mental and physical states while allowing for their conceptual and ontological distinction, and dispensing with the need for any spontaneous production of consciousness de novo by the brain. 

Both Draper and James recognize that aetherism leaves the door open to an afterlife, as well as certain psi phenomena. As Draper puts it, "perhaps William James was right to challenge the confidence that most philosophers and scientists have that there is no life after death. For if we don't know that aetherism is false, then we don't actually know that the subject of our psychological properties does not continue to exist after our bodies are destroyed.”
