“I shall not turn my life into a thin straight line which prefers abstractions to reality. I shall know what I am doing when I abstract, which of course I shall often have to do.” (An abstraction, as Piper explains it, would be to lump all trees together into one category of tree. Whereas to think concretely would be to see and savor a particular tree that you climbed when you were a child, or that your child delights to play in , or one that displays the beauty of fall in an amazing way.)
