Why do we so stubbornly cling to the assumption of mind? Despite the so far presented empirical, ontological, and conceptual-logical evidence against mind, the philosopher may nevertheless reject the world-brain problem as counter-intuitive. She/he will argue that we need to approach the question for the existence and reality of mental features in terms of the mind-body problem as it is more intuitive than the world-brain problem. Our strong adherence to mind is thus, at least in part, based on what philosophers describe as “intuition”, the “intuition of mind” as I say. How can we resist and escape the pulling forces of our “intuition of mind”? The main focus in this chapter and the whole final part is on the “intuition of mind” and how we can avoid and render it impossible. I will argue that we need to exclude the mind as possible epistemic option from our knowledge, i.e., the “logical space of knowledge”, as I say. The concept of “logical space of knowledge” concerns what we can access in our knowledge, i.e., our possible epistemic options that are included in the “logical space of knowledge”, as distinguished from what remains inaccessible to us, i.e., impossible epistemic options, as they are excluded from the “logical space of knowledge”. For instance, the “logical space of knowledge” presupposed in current philosophy of mind and specifically mind-body discussion includes mind as possible epistemic option while world-brain relation is excluded as impossible epistemic option. This, as I argue, provides the basis for our “intuition of mind” and the seemingly counterintuitive nature of world-brain relation. How can we modify and change the possible and impossible epistemic options in our “logical space of knowledge”? I argue that this is possible by shifting our vantage point or viewpoint - that is paradigmatically reflected in the Copernican revolution in cosmology and physics. Copernicus shifted the “vantage point from within earth” to a “vantage point beyond earth”; this enabled him to take into view that the earth (rather than the sun) moves by itself which provided the basis for his shift from a geo- to a helio-centric view of the universe. Hence, the shift in vantage point modified his epistemic options and thus expanded the presupposed “logical space of knowledge”. I conclude that we require an analogous shift in the vantage point we currently presuppose in philosophy of mind. This will expand our “logical space of knowledge” in such way that makes possible to include world-brain relation as possible epistemic option while, at the same time, excluding mind as impossible epistemic option. That, in turn, will render the world-brain problem more intuitive while the mind-body problem will then be rather counter-intuitive. Taken together, this amounts to nothing less than a Copernican revolution in neuroscience and philosophy – that shall be the focus in next chapter.
