Austin Hall and Homer Eon Flint, The Blind Spot (1951)
“ We all of us listened, the doctor most of all. “Go on,” he said.“Can’t you see?” repeated Watson. “There is affinity between substance and shadow; and therefore your spirit or shadow or what you will is concrete, is in itself a substance. It is material just as much as you are. Because you do not see it is no proof that it is not substance. That pot palm yonder does not see you; it is not blessed with eyes.”The doctor looked at Watson; he spoke gently.“This is very old stuff, my boy, out of your abstract philosophy. No man knows the secret of life. Not even yourself.” ”
