ABSTRACT
We are confronted by two kinds of functions, those of motor expression arid those of sensory comprehension, and we must consider how we ought to envisage the mechanism of these functions, which has been the object of such lively controversy and of such profound disagreement. We shall thus have to test the value of the idea of verbal images, rejected by Pierre Marie, motor images, and auditory or visual images, and to discover whether it is not necessary to give these expressions a sense different from the usual one—supposing they have a sense—or to substitute for them more comprehensive ideas. Finally we shall see how the connection between thought and language may be conceived, how we should envisage the nature ot internal language and its role in mental functioning as a whole, and how aphasia of the current type, that of Wernicke, in its sensory and intellectual setting, can be interpreted.
