The rational would say that rapport with the irrational depends purely upon chance. If, by some accident, the objective situations are exactly in tune, something like a human relationship takes place, but nobody can tell what will be either its validity or its duration. To the rational type it is often a very bitter thought that the relationship will last only just so long as external circumstances accidentally produce a mutual interest. This does not occur to him as being especially human, whereas it is precisely in this situation that the irrational sees a humanity of quite singular beauty. Accordingly each regards the other as a man destitute of relationships, upon whom no reliance can be placed, and with whom one can never get on decent terms. Such a result, however, is reached only when one consciously tries to make some estimate of the nature of one's relationships with one's fellow-men. Although a psychological conscientiousness of [p. 471] this kind is by no means usual, yet it frequently happens that, notwithstanding an absolute difference of standpoint, a kind of rapport does take place, and in the following way. The one assumes with unspoken projection that the other is, in all essential points, of the same opinion as himself, while the other divines or senses an objective community of interest, of which, however, the former has no conscious inkling and whose existence he would at once dispute, just as it would never occur to the latter that his relationship must rest upon a common point-of-view. A rapport of this kind is by far the most frequent; it rests upon projection, which is the source of many subsequent misunderstandings.
