art criticism

.. what is the use of art-criticism? Why cannot the artist be left alone, to create a new world if he wishes it, or, if not, to shadow forth the world which we already know, and of which, I fancy, we would each one of us be wearied if Art, with her fine spirit of choice and delicate instinct of selection, did not, as it were, purify it for us, and give to it a momentary perfection. It seems to me that the imagination spreads, or should spread, a solitude around it, and works best in silence and in isolation. Why should the artist be troubled by the shrill clamour of criticism? Why should those who cannot create take upon themselves to estimate the value of creative work? What can they know about it? If a man's work is easy to understand, an
explanation is unnecessary. . . .
