Here is one of the fundamental defects of American fiction--perhaps the one character that sets it off sharply from all other known kinds of contemporary fiction. It habitually exhibits, not a man of delicate organization in revolt against the inexplicable tragedy of existence, but a man of low sensibilities and elemental desires yielding himself gladly to his environment, and so achieving what, under a third-rate civilization, passes for success. To get on: this is the aim. To weigh and reflect, to doubt and rebel: this is the thing to be avoided.
