We have now passed in review the more important of the phenomena which are regarded as fruits of genuine religion and characteristics of men who are devout. Today we have to change our attitude from that of description to that of appreciation; we have to ask whether the fruits in question can help us to judge the absolute value of what religion adds to human life. Were I to parody Kant, I should say that a "Critique of pure Saintliness" must be our theme.
