John Henry Mackay's "Die Anarchisten" is a philosophical exploration of the contrasting principles of individualistic anarchism and communism. The book employs a biographical framework, drawing on the author's personal experiences and presenting the perspectives through two characters: Auban, representing Mackay's own individualist leanings, and Trupp, a fervent advocate for the communist worker's movement. The story unfolds through Auban's struggles within a movement that claims to be anarchist but clashes with his individualist beliefs, while also navigating the growing estrangement from his friend Trupp. Despite its philosophical underpinnings, the book reads at times like a novel due to its captivating narrative and Mackay's adept prose. This work had a significant influence on the European worker's movement, introducing Mackay's ideas, largely derived from the American individualist anarchist movement, to a new audience. "Die Anarchisten" sparked considerable discussion, particularly within socialist circles, after its publication in 1891.
