All landscapes have an inner and outer aspect to them. Part of the landscape is inside of us – in the mind – and the other part is outside of us – noticed by the senses. So where does that inner and outer qualia come from? God? Maybe. Maybe not. It is a conundrum with which philosophers have struggled for thousands of years.
The problems of philosophy (if we may sum up Bertrand Russell’s famous little book in a sentence), revolve around the fact that no line of reasoning can prove the existence of matter. All, apparently, is qualia. None-the-less, if you kick a rock it hurts your foot!
Ah, all that qualia must come from ecosystems! Ecosystems are both within and without us.
