Re: Difference between cognition and perception?

This rather interesting question impinges on models of perception generally.
If one holds that there is a substantive difference, and that cognition
rests on, and adds to, perception, then the distinction should be sharply
drawn. If, however, one holds that there is no good reason for drawing such
a distinction so clearly, then one treats perception and cognition as
holistically bound together, or even as different words for essentially the
same type of process.
My hunch is to suspect that the distinction is one that we've inherited as
axiomatic from Ancient Greek thought. Perception seems more closely tied to
sensation, and so is largely event-driven, whilst cognition is more
associated with the nuts and bolts of 'thinking about' things, and so is
more symbol-driven, a little more 'top-down'. So it has sometimes been
possible to to talk about 'direct perception' (sometimes, but not always, in
the same context as 'sense-perceptions'), but I don't remember coming across
'direct cognition'.
I'd rather like a clearer idea of the distinction, too.
