Skepticism: is an expression for the more or less well-formulated view that perceptual subjects cannot in principle have any security with regard to their knowledge about the external world. The doubts about the reliability of the sensory organs can be extended to doubts about the existence of an external world, if the possibility of a fundamental deception, for example by a permanent dream, is accepted. See also verification, evidence, perception, certainty, Moore's hands, solipsism.

David Chalmers on Skepticism - Dictionary of Arguments

I 74
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.
>Supervenience
, >Actual world, >Possible worlds.
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.
Cf. >Twin Earth.
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).
>Experience, >Consciousness/Chalmers.
I 76
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.
