My dear Colleagues and Friends:
It is a great disappointment to me not to be able to come to your country and participate personally in the very important and interesting Symposium.... The preparation of this lecture occupied all my thoughts, my time, and my hopes these last several months, and this work gave me great pleasure and satisfaction....
Ciba Foundation, The British Society of Cultural Relations with the USSR, my friends here and myself all did our best to arrange the trip to Sheffield but the stupidity of the whole arrangement system here, based on the law of counteraction much more than the laws of cooperation, was stronger. This 15 stage (15-wall) arrangement system from low to top level is the most shameful survival of past distrust in people and I hope very much that this system, as any other thing in the world, ages and will die with time.
