In any intellectual corner of modernity can be found such a phrase as I have just read in a newspaper controversy: “Salvation, like other good things, must not come from outside.” To call a spiritual thing external and not internal is the chief mode of modernist excommunication. But if our subject of study is mediæval and not modern, we must pit against this apparent platitude the very opposite idea. We must put ourselves in the posture of men who thought that almost every good thing came from outside–like good news. I confess that I am not impartial in my sympathies here; and that the newspaper phrase I quoted strikes me as a blunder about the very nature of life. I do not, in my private capacity, believe that a baby gets his best physical food by sucking his thumb; nor that a man gets his best moral food by sucking his soul, and denying its dependence on God or other good things. I would maintain that thanks are the highest form of thought; and that gratitude is happiness doubled by wonder.
