Books

In this book Bray offers imaginative, wide-ranging and perceptive critiques of robotics and complexity theory, as well as many amusing and telling anecdotes. The book taps into the findings of the new discipline of systems biology to show that the internal chemistry of living cells is a form of computation, although that sounds consuming it is written very clearly and understandably. 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? Bray proposes a startling and original answer. 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.
