Hi. I am not saying that "percept" is "reality" (and "percept" assumes
representationalism). Actually I did not say anything about my own view - at
least in what you quoted - but I will now. My view (and not one I invented
myself) is that perception is behavior. Some of it is reflexive, and
elicited by aspects of the world. Some of it is operant behavior and is, at
first, reinforced by its sensory consequences. Such behavior is, presumably,
also under stimulus control of aspects of the world. Later (after infancy)
perceptual responses become embedded in larger response classes that make a
more "macroscopic" contact with the world and are reinforced by the more
public consequences of those responses. This is somewhat technical, but it
has the quality of being brief.
