1. You may have received the impression that the results of our work of interpretation of the dream have left so much that is uncertain, despite our close adherence to technique, that a true translation of the manifest dream into the latent dream thoughts is thereby rendered impossible. In support of this you will point out that in the first place, one never knows whether a specific element of the dream is to be taken literally or symbolically, since those elements which are used symbolically do not, because of that fact, cease to be themselves. But if one has no objective standard by which to decide this, the interpretation is, as to this point, left to the discretion of the dream interpreter. Moreover, because of the way in which the dream work combines opposites, it is always uncertain whether a specific dream element is to be taken in the positive or the negative sense, whether it is to be understood as itself or as its opposite. Hence this is another opportunity for the exercise of the interpreter's discretion. In the third place, in consequence of the frequency with which every sort of inversion is practised in the dream, the dream interpreter is at liberty to assume such an inversion at any point of the dream he pleases. And finally you will say, you have heard that one is seldom sure that the interpretation which is found is the only possible one. There is danger of overlooking a thoroughly admissible second interpretation of the same dream. Under these circumstances, you will conclude there is a scope left for the discretion of the interpreter, the breadth of which seems incompatible with the objective accuracy of the results. Or you may also conclude that the fault does not rest with the dream but that the inadequacies of our dream interpretation result from errors in our conceptions and hypotheses.
