Anarchism without adjectives, in the words of historian George Richard Esenwein, “referred to an unhyphenated form of anarchism, that is, a doctrine without any qualifying labels such as communist, collectivist, mutualist, or individualist. For others, … [it] was simply understood as an attitude that tolerated the coexistence of different anarchist schools.”
