Title:  The Sciences and the Fullness of Rationality Author:  Alberto Strumia. Philip Larrey, Ph.D. and Peter Waymel, trans. Imprint:  The Davies Group, Publishers soft cover 164 pp. $20.00  US ISBN  978-1-934542-20-0 January  2010 A confrontation with scientific thought — an evaluation of the path it has followed and of the research it has led to today — Fides et Ratio [Latin: faith and reason], an encyclical promulgated by Pope John Paul II on 14 September 1998 dealing primarily with the relationship between faith and reason. One the one hand, we are dealing with a didactic perspective, which suggests a new approach to the epistemological problem, one that goes far beyond the usual, not to mention tiresome, popular prejudices. On the other hand, we are dealing with a research proposal that is philosophically and scientifically interesting. If, in the first Christian centuries, the cultural work believers faced (and some authors and schools of thought knew how to do it very well!) was that of confronting Greek philosophy and Roman law, which were presented as both theoretical and practical models of rationality, is it not true that Christians today must face the scientific model on an objective plane? And precisely at a time in which decisive questions about its foundations are emerging? We must hope that there are today, as there were in the Christian centuries of the past, intellects capable of addressing these questions positively, persons who have matured in the unity of knowing and living.

(the Catholic Theological Faculty) in Bologna. Beside being concerned with scientific topics (non-linear wave propagation, relativistic theories, irreversible extended thermodynamics, field theories and strings) his research was always especially addressed to interdisciplinary investigations comparing Aristotelian-Thomistic logic and metaphysics with the recent problems involving the theory of complexity, formal ontology and the problem of foundations. He is the author of several scientific and interdisciplinary articles and author and  editor of  more than twenty books, co-editor of the Interdisciplinary Dictionary of Religion and Science  (Dizionario interdisciplinare di scienza e fede, Rome 2002), is now vice-director of the on-line Interdisciplinary Encyclopedia of Religion and Science. This ttle is a translation of Le scienze e la pienezza della razionalità, Siena: Cantagalli, 2003
