Use "exteroception" in a sentence
"First, the main proponents of sense-datum theories advanced these theories mainly as theories of exteroception, that is, perception of external physical reality."
"So even if one finds the anti-sense-datum arguments convincing and rejects indirect realism of this kind for standard exteroception, there is still room for adopting a sense-datum theory for intransitive bodily sensations and for pain in particular."
"As a matter of fact, our conceptual practices treat seeing and other standard exteroception differently than they treat feeling pain, despite the fact that the types of information flow seem identical in both cases."
