" In describing the evolution of the various danger-situations from their prototype, the act of birth, I have had no intention of asserting that every later determinant of anxiety completely invalidates the preceding one. It is true that, as the development of the ego goes on, the earlier danger-situations tend to lose their force and to be set aside, so that we might say that each period of the individual's life has its appropriate determinant of anxiety. Thus the danger of psychical helplessness is appropriate to the period of life when his ego is immature; the danger of loss of object, to early childhood when he is still dependent on others; the danger of castration, to the phallic phase; and the fear of his super-ego, to the latency period. Nevertheless, all these danger-situations and determinants of anxiety can persist side by side and cause the ego to react to them with anxiety at a period later than the appropriate one; or, again, several of them can come into operation at the same time. It is possible, moreover, that there is a fairly close relationship between the danger-situation that is operative and the form taken by the ensuing neurosis. "

" The two techniques I refer to are undoing what has been done and isolating. The first of these has a wide range of application and goes back very far. It is, as it were, negative magic, and endeavours, by means of motor symbolism, to ‘blow away’ not merely the consequences of some event (or experience or impression) but the event itself. I choose the term ‘blow away’ advisedly, so as to remind the reader of the part played by this technique not only in neuroses but in magical acts, popular customs and religious ceremonies as well. [...] The same purpose may perhaps account for the obsession for repeating which is so frequently met with in this neurosis and the carrying out of which serves a number of contradictory intentions at once. When anything has not happened in the desired way it is undone by being repeated in a different way; and thereupon all the motives that exist for lingering over such repetitions come into play as well. [...] The second of these techniques which we are setting out to describe for the first time, that of isolation, is peculiar to obsessional neurosis. It, too, takes place in the motor sphere. When something unpleasant has happened to the subject or when he himself has done something which has a significance for his neurosis, he interpolates an interval during which nothing further must happen—during which he must perceive nothing and do nothing.

" The motor isolation is meant to ensure an interruption of the connection in thought. The normal phenomenon of concentration provides a pretext for this kind of neurotic procedure: what seems to us important in the way of an impression or a piece of work must not be interfered with by the simultaneous claims of any other mental processes or activities. But even a normal person uses concentration to keep away not only what is irrelevant or unimportant, but, above all, what is unsuitable because it is contradictory. He is most disturbed by those elements which once belonged together but which have been torn apart in the course of his development—as, for instance, by manifestations of the ambivalence of his father-complex in his relation to God, or by impulses attached to his excretory organs in his emotions of love. Thus, in the normal course of things, the ego has a great deal of isolating work to do in its function of directing the current of thought. And, as we know, we are obliged, in carrying out our analytic technique, to train it to relinquish that function for the time being, eminently justified as it usually is. "
