What do we know and how do we know it? A philosophy question for the ages.

What is internal to us and what is external? How does one influence the other?

This series of pieces includes a lot of shorter ones, not necessarily by me trying to make them more accessible (do I know that word:>), but trying to capture something that is in process: like the image you see from a moving train. Fields, a church, a small group of trees. Abandoned, derelict buildings; a small river with treed banks, meandering along with you, and then disappearing into the distant horizon.
