The snag of an art critic's life is that he is assessing something of no tangible value. The professional critic, or taster, of wine smells the bouquet and tastes the flavour of the sample, and knows of his sensitiveness and experience just what it is worth ; the professional critic, or inspector, of milk calls science to his aid and knows whether it is diluted with water or polluted with germs. But with a work of art, where reaction to it is a matter of opinion, tho most experienced critic may be hopelessly at sea. Will the majority of the future wish to tar and feather the works of Epstein, or to set him on Olympus And who will be the next Romney of Cavendish Square? Eric Newton, who broadcasts this evening, is art critic on the Manchester Guardian.
