In the tradition of as Erwin Schrödinger’s What Is Life? and Richard Dawkins’s The Selfish Gene, a distinguished cell biologist explains how living cells perform computations How does a single-cell creature, such as an amoeba, lead such a sophisticated life? How does it hunt living prey, respond to lights, sounds, and smells, and display complex sequences of movements without the benefit of a nervous system? This book offers a startling and original answer.In clear, jargon-free language, Dennis Bray taps the findings of the new discipline of systems biology to show that the internal chemistry of living cells is a form of computation. Cells are built out of molecular circuits that perform logical operations, as electronic devices do, but with unique properties. Bray argues that the computational juice of cells provides the basis of all the distinctive properties of living systems: it allows organisms to embody in their internal structure an image of the world, and this accounts for their adaptability, responsiveness, and intelligence.In Wetware, Bray offers imaginative, wide-ranging and perceptive critiques of robotics and complexity theory, as well as many entertaining and telling anecdotes. For the general reader, the practicing scientist, and all others with an interest in the nature of life, the book is an exciting portal to some of biology’s latest discoveries and ideas.

Cell Movements vividly describes how complex movements can arise from the properties and behaviors of biological molecules. This second edition is updated throughout with recent advances in the field and has a completely revised and redrawn artwork program. The text is suitable for advanced undergraduates as well as for professionals wishing for an overview of this field.

In his magnum opus De Trinitate, the twelfth-century canon Richard of St. Victor offers sustained reflection on core dogmatic claims from the Athanasian creed. At the heart of the treatise is Richard's argument for exactly three divine persons. Starting with the necessity of a single, maximally perfect divine substance, Richard reasons along four steps: (i) God must have maximal charity, or other-love; (ii) to be perfectly good, delightful, and glorious, God's other-love must be shared among at least two, and (iii) among at least three, divine persons; (iv) the metaphysics of divine processions and love each ensure the impossibility of four divine persons. Scripture and trustworthy church authorities already give Richard certainty in these truths of faith. Even so, as an act of ardent love, Richard contemplates the Trinity as reflected in creation. From this epistemic point of departure, he supports his conclusions from common human experience alone. Recently, philosophers of religion have employed Richard's trinitarian reflection as a springboard for constructive work in apologetics and ramified natural theology. His unique and meticulous approach to the Trinity has garnered attention from scholars of medieval and Victorine studies, recognizing the novelty and rigour of his philosophical theology. This volume presents the first focused exploration of Richard's central thesis in De Trinitate, combining historical context with philosophical scrutiny. It confronts the most challenging aspects of his argument, presenting Richard's insights as not merely intriguing but also profoundly compelling. His thesis, if validated, promises to significantly enrich modern dialogues on the philosophical and theological dimensions of the Trinity.
