Aquinas And Modern Science

The mission of Aquinas and Modern Science: A New Synthesis of Faith and Reason is precisely to invite you on a tour through the richness of Thomas's philosophy in its encounter with the sciences as we know them today. Let his time-tested principles continue to serve as an anchor of intelligibility in a sea of confusing claims.

Provides a sustained account of how the thought of Aquinas may be used in conjunction with contemporary science to deepen our understanding of divine action and address such issues as creation, providence, prayer, and miracles.

Peter Harrison takes what we think we know about science and religion, dismantles it, and puts it back together again in a provocative new way. It is a mistake to assume, as most do, that the activities and achievements that are usually labeled religious and scientific have been more or less enduring features of the cultural landscape of the West. Harrison, by setting out the history of science and religion to see when and where they come into being and to trace their mutations over timereveals how distinctively Western and modern they are. Only in the past few hundred years have religious beliefs and practices been bounded by a common notion and set apart from the secular. And the idea of the natural sciences as discrete activities conducted in isolation from religious and moral concerns is even more recent, dating from the nineteenth century. Putting the so-called opposition between religion and science into historical perspective, as Harrison does here for the first time, has profound implications for our understanding of the present and future relations between them.

This book provides a fundamental introduction to Aquinas's theology of the One Creator God. Aimed at making that thought accessible to contemporary audiences, it gives a basic explanation of his theology while showing its compatibility with contemporary science and its relevance to current theological issues. Opening with a brief account of Aquinas’s life, it then describes the purpose and nature of the Summa Theologica and gives a short review of current varieties of Thomism. Without neglecting other works, it then focuses primarily on the discussion of the One God in the first part of the Summa Theologica. God's transcendence and immanence is a recurrent theme in that discussion. Evidence of God's immanent causality in the natural world grounds Aquinas's five arguments for the existence of God (the Five Ways) which then open onto God's transcendence. The subsequent discussion of the divine attributes builds on the modes of God's causality established in the Five Ways. It also shows the need for a language of analogy to preserve God's transcendence and prevent us from reducing God to the level of creatures, even as qualities such as "goodness" and "love," which we first know from creatures, are applied to God. The discussion of God's providence and governance establishes that the transcendent Creator God is most intimately present in creation. God acts in all creatures in a way that does not diminish their proper causality, but is rather its source. As there is no contradiction between God's transcendence and immanence, so there is no competition between the primary causality of God and the secondary causality of creatures. Empirical science, which is limited by its method to the secondary causality of creatures, is shown to be compatible with the broader discipline of theology which also embraces the primary causality of the Creator.

This book introduces the Aristotelian-Thomistic view of the human person to a contemporary audience, and reviews the ways in which this view could provide a philosophically sound foundation for modern psychology. The book presents the current state of psychology and offers critiques of the current philosophical foundations. In its presentation of the fundamental metaphysical commitments of the Aristotelian-Thomistic view, it places the human being within the broader understanding of the world. Chapters discuss the Aristotelian-Thomistic view of human and non-human cognition as well as the relationship between cognition and emotion. In addition, the book discusses the Aristotelian-Thomistic conception of human growth and development, including how the virtue theory relates to current psychological approaches to normal human development, the development of character problems that lead to psychopathology, current conceptions of positive psychology, and the place of the individual in the social world. The book ends with a summary of how Aristotelian-Thomistic theory relates to science in general and psychology in particular. The Human Person will be of interest to psychologists and cognitive scientists working within a number of subfields, including developmental psychology, social psychology, cognitive psychology, and clinical psychology, and to philosophers working on the philosophy of psychology, philosophy of mind, and the interaction between historical philosophy and contemporary science, as well as linguists and computer scientists interested in psychology of language and artificial intelligence.

Aquinas's first proof for God's existence is usually interpreted as a metaphysical argument immune to any objections coming from empirical science. Connections to Aquinas's own historical understanding of physics and cosmology are ignored or downplayed. Nature and Nature's God proposes a natural philosophical interpretation of Aquinas's argument more sensitive to the broader context of Aquinas's work and yielding a more historically accurate account of the argument. Paradoxically, the book also shows that, on such an interpretation, Aquinas's argument is not only consistent with modern science, but actually confirmed by the history of science, from classical mechanics through 19th century thermodynamics to contemporary cosmology. The first part of the book considers Aquinas's argument in its historical context, exploring the key principles that everything in motion is moved by something else and that an infinite regress of causes is impossible. The structure of the First Way is analyzed and the argument is connected both with Aquinas's Third Way?a new interpretation of which is also proposed?and Aquinas's second proof from motion in the Summa contra Gentiles. To complete the account of what natural philosophy?prior to metaphysics?can demonstrate about God, a chapter on Aquinas's teleological argument (the Fifth Way) is also included. The second part of the book tracks the history of modern science from Copernicus to today, showing how Aquinas's argument fared at each major turn. The first chapter shows how Newton's understanding of inertia and conservation of momentum supports the idea that motion cannot continue forever without God's causality, and integrates a modern understanding of inertia and gravity with the principles of Thomistic natural philosophy. The second chapter considers the first and second laws of thermodynamics, showing how they too support Aquinas's contention that motion cannot continue forever without God's causality. This chapter also discusses statistical mechanics and contemporary cosmology, demonstrating that science continues to support Aquinas's unmoved mover argument. The final chapter turns to modern biology as well as cosmological fine-tuning to show that modern science also continues to support Aquinas's teleological argument. The result is not only a satisfying defense of Aquinas's natural philosophical proofs for God's existence, but a primer on the broader project of integrating Thomistic natural philosophy with modern science.
