The law of interacting phenomena,

The law of interacting phenomena, mentioned by Rudolf Steiner in the lecture quoted, is one to which he refers on other occasions, always as though he were passing on widely known occult facts. For instance, in the 8th lecture of the First Scientific Lecture Course, First Scientific Lecture Course, [Ten lectures given at Stuttgart December 23, 1919, to January 3, 1920. Published by the Natural Science Section of the Goetheanum, 1925. English edition, translated by George Adams, issued by the Goethean Science Foundation, Clent Worcs.] he says:

You have a pendulum clock; you wind it up and set it going. In the same room you have another pendulum clock: it must, admittedly, be of a certain type. This second clock you do not wind up. Under favourable circumstances you may sometimes discover that gradually this clock starts of its own accord. We will call this the “mutual sympathy” between phenomena, it can be investigated in a very wide domain. A last phenomena of this type, still connected to some extent with the outer world, could be examined far more frequently than it generally is, for it occurs very often. Times without number you may have had this experience. You are at table with another person and he says something you have just been thinking. You were thinking it but did not say it; he now says n. It is the sympathetic going-together of events (or complexes of events which is here making itself felt in a highly spiritual realm. We need to recognise the whole range of continuity from the simple resonance of a violin string, which one may still interpret crudely and unspiritually within the sequence of outer material events, to these parallel phenomena which appear so much more spiritual — as when we experience one another's thoughts.
