Skepticism/Chalmers: if it is only about our actual world, and we know that, e.g. biological phenomena are determined by microphysical facts, there is no room for skepticism. The biological are logically supervenient on the physical facts.
It is a different matter if we accept a second possible world, which is not different from ours in terms of perceptible facts, but differs with respect to the microstructure.
It is a different matter again if we assume phenomena which are not logically supervening on physical structures. Our example of this is our conscious experience (consciousness).
Skepticism/Consciousness/Chalmers: for our purposes - namely to explore the consciousness (conscious experience) - we simply assume that the external world exists and put skepticism to the back. All our evidence supervenes logically on the micro-physical facts.
