Goethe, in giving an account of how he came to write “Werther” as a series of letters, discusses the matter with his usual perspicuity, and lets us see how habitually conversational was his way of thinking. Speaking of himself in the third person, he says: “Accustomed to pass his time most pleasantly in society, he changed even solitary thought into social converse, and this in the following manner: He had the habit, when he was alone, of calling before his mind any person of his acquaintance. This person he entreated to sit down, walked up and down by him, remained standing before him, and discoursed with him on the subject he had in mind. To this the person answered as occasion required, or by the ordinary gestures signified his assent or dissent—in which every man has something peculiar to himself. The speaker then continued to carry out further that which seemed to please the guest, or to condition and define more closely that of which he disapproved; and finally was polite enough to give up his own notion.... How nearly such a dialogue is akin to a written correspondence is clear enough; only in the latter one sees returned the confidence one has bestowed, while in the former one creates for himself a confidence which is new, everchanging and unreturned.”[15] “Accustomed to pass his time most pleasantly in society, he changed even solitary thought into social converse,” is not only a particular but a general truth, more or less applicable to all thought. The fact is that language, developed by the race through personal intercourse and imparted to the individual in the same way, can never be dissociated from personal intercourse in the mind; and since higher thought involves language, it is always a kind of imaginary conversation. The word and the interlocutor are correlative ideas. The impulse to communicate is not so much a result of thought as it is an inseparable part of it. They are like root and branch, two phases of a common growth, so that the death of one presently involves that of the other. Psychologists now teach that every thought involves an active impulse as part of its very nature; and this impulse, with reference to the more complex and socially developed forms of thought, takes the shape of a need to talk, to write, and so on; and if none of these is practicable, it expends itself in a wholly imaginary communication.
