Review of the hardback: '… Camilleri has written an excellent and a scholarly high-level book that helps us understand the many important differences that existed among the main figures in the development of the Copenhagen Interpretation … an important work that may enlighten us in the ongoing discussion about the interpretation of quantum mechanics.' Metascience
'This excellent work is well researched, balanced and clear … It offers a new perspective on Heisenberg's philosophical commitments, especially of his later years and adds new depth and detail to his legacy as philosopher-physicist. It will be of considerable interest to anyone studying the history and philosophy of quantum mechanics.' Foundations of Physics
