Perception/Vision/Tradition/Epistemology/Millikan: Thesis: Perception is passive.
MillikanVsTradition/MillikanVsEpistemology: Perception is nothing passive! We are focussing our attention and are constantly asking ourselves decision questions. "Is it alive? Is it moving?"
Often, we relate to other things in order to identify them.
Therefore, abilities are the same as implicit intensions.
Implicit Intension/Millikan: but an implicit intension is not a "stimulus meaning".
