Sure. I should have defined the terms. To me the 'presence' is self-evident awareness "I exist". No one can deny "I exist" without proving it.
Presence, according to the Seager, is undeniable. He says
"We could be wrong about many things connected to our states of consciousness, but we cannot be mistaken about the existence of an immediately available source of information present to the mind. Consider your belief that something exists or that something is happening right now. As Descartes famously noted, this proposition is in a different category from most quotidian knowledge. It is in the category of things that you could not be wrong about. So there must be some source of information that vouchsafes your unassailable claim that something is happening. This source is the ‘present to mind’ we call consciousness."
The idea of what is fundamental reality can vary from person to person. Currently, however, we consider that physics informs us about the objective fundamental reality. Currently, mass, angular momentum, and spin are three basic parameters that are supposed to characterise the fundamental material that constitutes the black holes to the universe. This fundamental reality, as peer Seager, is not available to us.
Seager formulates the problem: How that which is unassailably present to the mind but how it could arise from un-present physical reality?
