Zen does not confuse spirituality with thinking about God while one is peeling potatoes. Zen spirituality is just to peel the potatoes.
The pattern of a newspaperman's life is like the plot of 'Black Beauty.' Sometimes he finds a kind master who gives him a dry stall and an occasional bran mash in the form of a Christmas bonus sometimes he falls into the hands of a mean owner who drives him in spite of spavins and expects him to live on potato peelings.
Introspection and preserved writings give us far more insight into the ways of past humans than we have into the ways of past dinosaurs. For that reason I'm optimistic that we can eventually arrive at convincing explanations for these broadest patterns of human history.
