Dear Phil,
Now it is you who are oversimplifying. No matter how you talk about our
perceptual equipment, or that which is processed by it, you are still talking
about phenomena. What their basis might be in a possible transcendent reality
is beyond our ability to know.
Your statement that "There is objective reality" is a statement of belief,
just as the following paragraph in which you talk about God. These are not
matters of proof. The second is a matter of faith, while the first is the
best hypothesis we can come up with to explain certain problematic aspects of
phenomenological experience.
