There is a whole school of philosophy built around looking at a tree. Looked at from earth the tree is still , looked at from off earth the tree is moving. We can experience joy , ecstasy , anguish and despair and everything in between. The philosophical debate has been going on for centuries and we're still at it. Stephen Hawking tries to say Philosophy is a dead science , but as long as humans are walking the planet I think we're going to wonder where we are , why we're here and what it's all about.
