 This a strange misinterpretation of Dave's point?

 What I, and probably Dave, are saying, is this:  What we see is our
interpretation of the external world.  Surely the retinal image contributes
much of the information that goes into this interpretation, so the
correspondence between what we see and what is out there is hardly
astonishing at all.  But we may also see a bird which is so small that
it would be inconspicuous were it not that the sounds picked up by our
ears contributed to the interpretation.  We may also see a various objects
which are not there at all but whose presence we interpret by interpolation
from what is there and from our memory processes.
