"[W]ithin the strictly anarchist world we find some theorists like Ricardo Mella, who, due to his knowledge of the English language, knows deeply the work of [Benjamin] Tucker and that of the north American individualists, especially by reading regularly the British magazine Freedom and the north American ones The Alarm (Chicago) and the tuckerian Liberty (Boston). [...] Uncomfortable within the polemics between collectivists and libertarian communists, the Galician anarchist tries to integrate the different ideological currents under the proposal of Tarrida del Mármol of an anarchism without adjectives".
