Full Idea
There is no need of a theory to reconcile what we know about sense data and what we believe about physical objects, because part of what we mean by saying that a penny is round is that we see it as elliptical in such and such conditions.
Gist of Idea
Part of what we mean by stating the facts is the way we tend to experience them
