Wait a minute. That the English language multiple definitions for "feelings" includes sensation, emotion, hunches, etc. means we need to be very careful about not conflating the different meanings.
How do you relate arguments about sensation to feelings as emotion or hunches, etc? My guess is that emotional feeling result in responses in the body that are picked up by the sensory systems. But this is not a simple argument that "I perceive a sensation therefore external reality exists."
Feeling the bark of a tree.
Is an inadequate example and possibly an invalid example.
