We are publishing for the first time the full text of David Bruce’s critique of the bastardization of dialectics that Gerry Healy foisted on the International Committee in the 1970s and 1980s. David Bruce joined what was then the Socialist Labour League in the late 1960s and soon afterwards the staff of its printshop. He worked there continuously until the WRP broke up in 1985. Though ‘elected’ to its Central Committee early in 1984, he was primarily a technician, not a political leader. He was, however, one of a soon-to-be-notorious group that worked covertly to expose what its members saw as Healy’s personal and the wider movement’s political corruption. His essay was at the time and remains to this day the most comprehensive and insightful analysis of the philosophical outlook that Healy called ‘the practice of cognition’. Yet Bruce’s contribution to the attempts to overcome the disorientation within the International Committee in those years has been unjustly forgotten.
