Mikhail Bakunin
A draft of my translation: I've used a Spanish translation from 1936 as another primary source I can read better, "Vida de Malatesta." This was published by the Guilda de Amigos del Libro in Barcelona, and translated from Italian by Diego Abad de Santillan.

A later book called "Malatesta: L'uomo e il pensiero" in its original Italian starts with an identical first half as the book I'm reading, but takes an additional section to develop his ideas specifically. Transcribed by a milanese anarchist circle.

"An Anarchist Programme," a platform that Malatesta prepared for the 1920 Congress of the Italian Anarchic Union at Bologna, backed with "Anarchist Propaganda." From Zabalaza books.
