From the NYT article Master of the Form

The Function of Criticism “The most important qualification which I have been able to find, which accounts for the peculiar importance of the criticism of practitioners, is that a critic must have a very highly developed sense of fact. This is by no means a trifling or frequent gift. And it is not one which easily wins popular commendations. The sense of fact is very slow to develop, and its complete development means perhaps the very pinnacle of civilization.”
