Sui generis
In sociology, the "sui generis" is what has been externalized, then internalized in the overall public and becomes a part of society that simply exists in its construct. It is not something that is not thought to have been created, because it is imbedded in everyone's way of thinking and being. Instances include the idea of love, or going to school, or clothing belonging to a specific gender. These examples are "sui generis" for they simply exist in society and are widely accepted without thoughts of where they come from or how they were created.
Fourth International
In the wake of the World Congress, the line of the International Leadership was generally accepted by groups around the world, including the U.S. SWP whose leader, James P. Cannon, corresponded with the French majority to support the tactic of entrism "sui generis". At the same time, however, Cannon, Healy and Mandel were deeply concerned by Pablo's political evolution. Cannon and Healy were also alarmed by Pablo's intervention into the French section, and by suggestions that Pablo might use the International's authority in this way in other sections of the Fourth International that felt entrism "sui generis" was not a suitable tactic in their own countries. In particular, minority tendencies, exemplified in Britain by John Lawrence and in the U.S. by Bert Cochran, to support entrism "sui generis" hinted that Pablo's support for their views indicated that the International might also demand Trotskyists in those countries adopt that tactic.
