It is virtually impossible to ascertain which of several versions of the Treatise that appeared during his lifetime best reflected Becccaria's own thought. His use of many ideas of Enlightenment thinkers also makes it diffi cult to interpret what he has written. While Enlightenment thinkers wanted to break the chains of religion and advocated free men and free minds, there was considerable disagreement as to how this might be achieved, except in the most general terms.
The editors have based this translation on the Francioni (1984) text, by far the most exhaustive critical Italian edition of Dei delitti e delle pene. This edition is undoubtedly the last that Beccaria personally oversaw and revised. This new translation, which includes an outstanding opening essay by the editors, is a welcome introduction to Beccaria and to the modern beginnings of criminology.
