More than once in my youth the psychological importance of such a symbol had become clearly evident to me and from a sentimental point of view also it was advisable. In Berlin, after the War, I was present at a mass-demonstration of Marxists in front of the Royal Palace and in the Lustgarten. A sea of red flags, red armlets and red flowers was in itself sufficient to give that huge assembly of about 120,000 persons an outward appearance of strength. I was now able to feel and understand how easily the man in the street succumbs to the hypnotic magic of such a grandiose piece of theatrical presentation.
