From the reviews:

"The belated publication of de Finetti's lectures provides a welcome opportunity to celebrate the achievements of one of the remarkable thinkers of the last century and also to look again at his work as a whole." N. H. Bingham, Imperial College London

“The editor made an extraordinary effort to put the lectures as well as the discussions into proper context through a set of notes. These are very useful, and they often describe the future evolution of a subject which is touched on in the main text. A biographical sketch of de Finetti written by M. C. Gallavotti completes the information given in the book. … I am grateful to the editor … for making these lectures available in English to a broader audience.” (Enrico Scalas, Mathematical Reviews, Issue 2012 f)
