The Uncommercial Traveller is a collection of Dickens's memories rather than of his literary purposes; but it is due to him to say that memory is often more startling in him than prophecy in anybody else. They have the character which belongs to all his vivid incidental writing: that they attach themselves always to some text which is a fact rather than an idea. He was one of those sons of Eve who are fonder of the Tree of Life than of the Tree of Knowledge—even of the knowledge of good and of evil. He was in this profoundest sense a_r_e_al_i_s_t. Critics have talked of an artist with his eye on the object. Dickens as an essayist always had his eye on an object before he had the faintest notion of a subject. All these works of his can best be considered as letters; they are notes of personal travel, scribbles in a diary about this or that that really happened. But Dickens was one of the few men who have the two talents that are the whole of literature—and have them both together.
