It is a shame I do not understand him (Paul)

Yet even in the loneliness of the canyon I knew there were others like me who had brothers they did not understand but wanted to help.  We are probably those referred to as "our brother's keepers," possessed of one of the oldest and possibly one of the most futile and certainly one of the most haunting of instincts.  It will not let us go.
