Cambridge University Press 978-1-107-17624-9 — Dance to the Tune of Life Denis Noble Frontmatter More Information DANCE TO THE TUNE OF LIFE BIOLOGICAL RELATIVITY In this thought-provoking book, Denis Noble formulates the theory of biological rel- ativity, emphasising that living organisms operateatmultiplelevelsofcomplexityand must therefore be analysed from a multi-scale, relativistic perspective. Noble explains that all biological processes operate by means of molecular, cellular and organismal networks. The interactive nature of these fundamental processes is at the core of bio- logical relativity and, as such, challenges simpliied molecular reductionism. Noble shows that such an integrative view emerges as the necessary consequence of the rig- orous application of mathematics to biology. Drawing on his pioneering work in the mathematical physics of biology, he shows that what emerges is a deeply humane pic- ture of the role of the organism in constraining its chemistry, including its genes, to serve the organism as a whole, especially in the interaction with its social environ- ment. This humanistic, holistic approach challenges the common gene-centred view held by many in modern biology and culture. Denis Noble is Emeritus Professor of Cardiovascular Physiology and Director of Computational Physiology at the University of Oxford, UK. He is the current President of the International Union of Physiological Sciences and a Fellow of the Royal Society. © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-1-107-17624-9 — Dance to the Tune of Life Denis Noble Frontmatter More Information DANCE TO THE TUNE OF LIFE BIOLOGICAL RELATIVITY Denis Noble The University of Oxford, UK © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-1-107-17624-9 — Dance to the Tune of Life Denis Noble Frontmatter More Information University Printing House, Cambridge cb2 8bs, United Kingdom One Liberty Plaza, 20th Floor, New York, ny 10006, USA 477 Williamstown Road, Port Melbourne, vic 3207, Australia 4843/24, 2nd Floor, Ansari Road, Daryaganj, Delhi – 110002, India 79 Anson Road, #06–04/06, Singapore 079906 CambridgeUniversityPressispartoftheUniversityofCambridge.

That refers to all parts of organisms. All the molecules, organs and systems dance to the tune of the organism and its social context. Those molecules include the sequences of DNA we now call genes. r How do all these components of life dance together in harmony? r When did their billion-year dance begin? r What makes them dance? r Why is their dance relativistic? r What do we mean by a ‘gene’? r What do we mean by ‘life’? r How can ‘life’ depend on ‘dead’ molecules? r And what is Biological Relativity? Theanswerstothesequestionsformthesubjectofthisbook.We will also address the question of meaning. Could all this really happen as a consequence of ‘blind chance’? And what could that commonly used phrase possibly mean? What, indeed, do we mean by ‘meaning’? Could meaning itself be subject to a relativity principle: a relativity of epistemology? If these questions fascinate you, then read on. You will not need to know a lot of science to understand the book: whatyouwillneedisanewsetofeyes.Iwillencouragethereader to adopt the eyes and mind of an inquisitive explorer. The scientiic knowledge you need to know will mostly be in the book. If you already know a lot of science, you may need to relearn what you thought you knew. Because
