I have read "Cooperation on the Left" with considerable interest. I t tempted me to essay a brief reaction. Cooperation, to be sure, is always a desideratum in any social movement, but it may be doubted whether cooperation is ordinarily achieved by seeking it directly for its own sake. The various sectors of the Left must have something rather specific to cooperate with and for. During the period centering about 1940, there was considerable cooperation among progressives in the United States principally because there was a great leader of our nation on the Left. He has been followed by a relatively weak and inconsistent leader, consequently the Left has virtually lost its common focus of allegiance.
