[Excerpt] The labor movement has hurt itself in recent years with a childish tendency to elevate tactical questions to the level of principles. And nowhere more than the "principle" of militancy versus cooperation and participation. These are tactics. Their use or rejection is not a decision that should be decided by some a priori considerations of ideological purity or unity of interest between labor and management, but by what will work in a given situation—particulars of condition, time and place.
