"The author is a distinguished historian of philosophy, who contributed to the Bruno Studies with outstanding works … the reader is presented with a well-balanced account of Bruno’s bio-bibliography and a dynamic overview of his ideas in their development … a very useful introduction to Bruno’s philosophy" – in: Metascience, July 2013"[Giordano Bruno] had the misfortune to live in an era of conflict between Catholics and Protestants. Unwilling to keep silent, and unable to fit his beliefs to the acceptable party line of either side, he stayed mostly in motion. Blum’s book works hard to keep up with him. It will be of most use to students and specialist scholarly readers in the history of philosophy." – in: Reference and Research Book News 27/6 (December 2012)
