Until now I am still making abstract statements. I assert that there is a two-way relationship between thinking and reality, and when operating simultaneously in both directions it will bring an element of uncertainty into the minds of the attendees and an element. uncertainty into the course of events. I call this two-way relationship feedback, and consider that feedback is the difference between unique historical events and boring daily developments. Now I have to give some specific evidence that historical events like this do indeed take place, and indeed they are of historical importance.
