Full Idea
When we acquire new evidence in perception, we do not first acquire unknown evidence and then somehow base knowledge on it later. Rather, acquiring new is evidence IS acquiring new knowledge.
Gist of Idea
We don't acquire evidence and then derive some knowledge, because evidence IS knowledge
