(1912)
“ As a painter, he lacked something on the sensuous side. He was fond of asserting the partial truth that art is science. In distilling from a natural scene such constituents as can be fused into a simple, sternly concentrated, æsthetic unity Whistler has never been surpassed. It is only when we seek the touch of excess, the hint at some personal, irresponsible preference, through which genius so often speaks, that we feel a slight stirring of disappointment. ”
