The Progressive International, a Global Green New Deal and the Limits of ‘Left Unity’ — Ebb Magazine

One must not allow oneself to be misled by the cry for ‘unity.’ Those who have this word most often on their lips are those who sow the most dissension… Those unity fanatics are either the people of limited intelligence who want to stir everything up together into one nondescript brew, which, the moment it is left to settle, throws up the differences again in much more acute opposition because they are now all together in one pot … or else they are people who consciously or unconsciously … want to adulterate the movement.

Frederick Engels, June 1873
