The spirit of an age may be best expressed in the abstract ideal arts, for the spirit itself is abstract and ideal.
Nothing, indeed, is more dangerous to the young artist than any conception of ideal beauty: he is constantly led by it either into weak prettiness or lifeless abstraction: whereas to touch the ideal at all, you must not strip it of vitality.
If you meet at dinner a man who has spent his life in educating himself you rise from the table richer, and conscious that a high ideal has for a moment touched and sanctified your days.
