|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.

|Stegmüller IV 379
Skepticism / Berkeley / Stegmüller: he will not defend skepticism or even suggest it. - Rather, he attempts to prove that the assumption that there is an independent material world, cannot be formulated without contradiction. - The internal state is the same, if the perceived objects do not exist. - To distinguish, we must specify the beliefs that are associated with the internal state. - But that does not oblige us to share those beliefs with others. - Therefore, we will never know if the skepticism is true._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
