Full Idea
To the objection that one is never aware of inferences in sensation, the unconvincing reply comes that such inferences are automatic, telescoped, non-discursive and unconscious.
Gist of Idea
Inference in perception is unconvincingly defended as non-conscious and almost instantaneous

A Reaction
I think the 'unconvincing' reply is a bit more convincing in the light of modern research on the brain, which presents everything it does in a far less conscious light than the traditional view. Even reason seems barely conscious.
