D'Ettore's book is one of the best monographs on this subject in at least the last fifty years, suitably elaborated with the most updated sources and secondary literature and with a true philosophical understanding that, together with a rigorously historical procedure, makes it particularly understandable and useful. It makes us better understand the importance of 'post-Thomasian' Thomism, when his disciples tried to solve a question to which Aquinas had not yet given any or very vague answers and when one has to choose between different texts of Thomas and develop those more sustainable positions with reasonable arguments and independent of his own authority.""—Angelicum ""Markedly valuable as an example of a luminous approach to complex issues, developing coherently all the important ideas and stages of the development of Aquinas' doctrine of analogy in the writings of Thomists. Recommended to all those who are interested in the teachings of Thomas Aquinas (in which analogy maintains a crucial role), in Thomism as such, or in the doctrine of analogy itself, which is still the cornerstone in metaphysics and natural theology when articulating the relationship between God, the world and creatures.""—European Journal for the Study of Thomas Aquinas ""D'Ettore teaches Thomists an important lesson: fidelity to the Thomist tradition is measured not by fidelity to the texts of Aquinas but to the pursuit of truth exhibited by Aquinas's enquiries. Before reading this book, I knew my nescience on analogy ran deep, I am grateful to D'Ettore for helping me sound how many fathoms deeper it is and for trailblazing a way through the tricky terrain of Thomist answers to analogical problems.""—Reviews in Religion and Theology
