What is mentioned here involves one of the deepest, most serious,
most dangerous ethical/political problems of our day and brings it
into the laboratory: - *systematic external control of emotions*.
There lie the dangers, the nettle that must be grasped.
Nevertheless, there is also a positive side that can and must be
developed systematically if we are to survive - it is a Rubicon we
must cross. At this moment one can say no more.
