The shape of the theatre had been chosen for acoustic reasons, on account of certain properties of the hyperbola, which I had not the mathematics to understand, but which, Fabian said, had been utilised in the third (1914–1918) of the five great wars of European settlement, for finding out by their report, the exact post of hidden guns. It was this which had enabled the fairfusser to make the last cry seem to come from the void; the other speeches had merely been delivered by variously placed loud-speakers, connected in due turn with a wireless gramophone. I may here say that the phrases I have remembered and written down are only a very small number of those used in the performance, and which, for some reason, seemed familiar. The other words spoken in the clutch were of like great emotive power, chosen or invented by the fairfusser for this reason alone: and though they may seem to have no logical thread, or connection in real life, their place in the scheme was very carefully thought out. The reasons, and the terminology, for all this were too far advanced for me to be able to hold them in my head, but I have since traced some passages Fabian showed me as early sources of the form, and which will give the reader some idea of the great cleverness of the design. “Thus the indirect methods of hypnotising, like many of the technical procedures used in making jokes, have the effect of checking certain distributions of mental energy which would interfere with the course of events in the unconscious, and they lead eventually to the same result as the direct methods of influence by means of staring or stroking.”[4] [4] Freud, _Group Psychology and the Analysis of the Ego_, page 97.
