“Criticism is the disengaging and weighing of these values into which men transmute their experience and from which alone experience derives both its meaning and its form. Hence the contention between two first rate critics is more significant than the struggle between armies with banners for what they are contending about so soon as they arise above the merely philological level is nothing less than the structure of the universe, the nature of the man, the meaning of life, the right goal of all thought, and the proper aim of all endeavor.”
