Stroud I 105f
Knowledge/proof of existence/existence/Hume/Stroud: there are two principles:
1. No one knows of the existence of something when it is not perceived directly by someone > Apprehension: is unordered or the person knows what he/she has perceived directly, is a sign of the existence of this thing.
2. No one can know that a thing is a sign of something else, if he/she has not perceived these two things (thing and sign) directly.
MooreVsHume: both principles are wrong: e.g. I know that this pencil exists. According to Hume I could not know that, so they are wrong. This is a reductio ad absurdum.
StroudVsMoore: Hume's principles are valid.
>Principles/Hume.
Moore: for him it is relevant what is safe, the pencil or the principles.
Skepticism/Stroud/(s): but skepticism is not a question of certainty.
