Objective Truth? The brain does not fabricate a rectangular picture of an object explained away as invisible. — jkop
Except that is exactly what happens in one of the most famous optical illusions. We simply do not see an exact map of the photons received at the retina. Apart from the fact that the very structure of the eye makes that impossible (not least because there's a hole in the retina) we know that the information sent to the visual cortex is heavily manipulated, most obviously in the resolving of two different images into a single one (you seem to have conveniently forgotten that we have two eyes in conflict at the reception end).
The famous yellow cast problem faced by photographers gives more than adequate evidence that the colours we see are adjusted constantly by the brain according to the time of day. We know that people whose languages do not distinguish particular colours cannot see those colours as distinct without considerable effort. Again from photography we know that parallax issues are straightened out. From the famous shrinking room illusion which is just as effective in 3D as in 2D we know that the apparent size of objects is often completely a matter of cognitive process.
The evidence is overwhelming that what we see is a heavily edited version of the images falling on our retinas and that our vision is impressionistic at best. It bears as much relation to reality as it needs to allow us to move around and manipulate objects without falling over too often and no more. The brain is always the dominant partner in the sensor, signal, display loop to the extent that it can literally make us see things that are not there. That is the inescapable conclusion of a vast wealth of experimental evidence, believe it or not!
