Epiphenomenalism is a mind-body dualist proposal that states that the brain can affect the mind but the mind cannot affect the brain. However, it has a big problem. It doesn't explain why the brain knows about the mind (qualia).
"The most powerful argument against epiphenomenalism is that it is self-contradictory: if we have knowledge about epiphenomenalism, then our brains know about the existence of the mind, but if epiphenomenalism were correct, then our brains should not have any knowledge about the mind, because the mind does not affect anything physical."
One of the proposed solutions is that God programs in our belief of our own qualia. How can one solve this problem without invoking God?
