The Web of Life

Overview

Fritjof Capra's The Web of Life: A New Scientific Understanding of Living Systems (1996) is the intellectual culmination of a project he began with The Tao of Physics (1975). Where that earlier book drew parallels between quantum physics and Eastern mysticism, The Web of Life shifts focus from physics to the life sciences. Capra's ambition is nothing less than a new scientific paradigm — a conceptual framework that unifies biology, cognition, ecology, and even social organization under a single systemic vocabulary. The book synthesizes the work of a generation of revolutionary scientists: Ilya Prigogine's dissipative structures, Humberto Maturana and Francisco Varela's autopoiesis, Gregory Bateson's ecology of mind, James Lovelock's Gaia hypothesis, and Benoit Mandelbrot's fractal geometry. Capra's core argument is that these diverse developments converge on a single insight: life is not a substance but a pattern — a self-organizing network that continually produces itself.

Why This Book Matters

The Web of Life matters because it offers a rigorous, scientifically grounded alternative to the mechanistic paradigm that has dominated Western thought since the seventeenth century. Capra does not merely critique reductionism; he assembles the conceptual tools for a genuinely systemic biology. The book has influenced ecological education (Capra co-founded the Center for Ecoliteracy), informed the field of complexity studies, and provided a theoretical foundation for the deep ecology movement. It remains one of the most accessible yet comprehensive introductions to systems thinking as applied to living systems — a bridge between the natural sciences, the humanities, and ecological ethics.

Preface

Capra opens by stating that the book is the fruit of more than two decades of thinking about the conceptual foundations of modern science. He traces his intellectual journey from The Tao of Physics, through The Turning Point (1982), to the present work. The central question that drives the book: "What is life?" Capra acknowledges that molecular biology has made spectacular progress in understanding the chemistry of living organisms, but argues that it has not brought us closer to understanding the nature of life itself. The book aims to synthesize the emerging systemic understanding of life that has developed across multiple disciplines — from biology and ecology to cognitive science and complexity theory.

Part One: The Cultural Context

Chapter 1: Deep Ecology — A New Paradigm

Capra establishes the cultural and philosophical context for the scientific revolution he will describe. The crisis of perception that afflicts modern civilization — environmental degradation, social fragmentation, spiritual emptiness — stems, he argues, from the dominance of a mechanistic worldview inherited from Descartes and Newton. This worldview fragments reality into separate parts, treats nature as a machine to be exploited, and divorces facts from values.

Against this, Capra presents the emerging paradigm shift: from the parts to the whole, from analysis to synthesis, from reductionism to holism. He introduces deep ecology — a movement founded by Arne Naess — as the philosophical expression of the new paradigm. Deep ecology recognizes the intrinsic value of all life forms and the fundamental interconnectedness of all phenomena. It shifts from anthropocentric (human-centered) to ecocentric (Earth-centered) values. Capra is careful to distinguish deep ecology from "shallow environmentalism," which merely seeks to manage nature more efficiently within the existing paradigm.

The chapter closes by setting the agenda for the rest of the book: to show that the new scientific understanding of life — grounded in systems thinking, complexity theory, and ecology — provides the intellectual foundation for a deep ecological worldview.

Part Two: The Rise of Systems Thinking

Chapter 2: From the Parts to the Whole

This chapter traces the historical development of systems thinking from its origins in the 1920s to its maturation in the 1970s. Capra begins with the "organicist" biologists of the early twentieth century — Ludwig von Bertalanffy, Paul Weiss, Joseph Needham, and others — who rejected the mechanistic biology of their day and sought to understand organisms as integrated wholes.

Bertalanffy's General System Theory (GST) was the first systematic attempt to develop a theoretical framework applicable to all systems, whether biological, psychological, or social. Capra explains the key concepts that emerged from GST: the distinction between open and closed systems; the principle that the whole is more than the sum of its parts; the concept of emergent properties that arise from the organization of a system rather than from its components alone.

The chapter also covers the development of cybernetics, which emerged from the Macy Conferences (1946-1953) where Norbert Wiener, John von Neumann, Claude Shannon, and others developed the concepts of feedback, information, and control. Capra highlights Gregory Bateson's radical extension of cybernetic ideas to the mind, arguing that mental processes are not confined to the brain but are immanent in the entire living system.

Chapter 3: Systems Theories

Capra provides a structured overview of the various systems theories that have developed since Bertalanffy. He distinguishes between "hard" systems thinking (mathematical systems theory, cybernetics, information theory) and "soft" systems thinking (interpretive approaches that acknowledge the role of human perception and values).

Key concepts covered include:

• Open and closed systems: Living systems are thermodynamically open (they exchange energy and matter with their environment) but organizationally closed (their internal structure is self-determining).
• Feedback loops: Negative feedback counteracts deviation and maintains stability; positive feedback amplifies deviation and drives change.
• Emergence: Properties arise at higher levels of complexity that cannot be predicted from analysis of lower-level components.
• Self-organization: The spontaneous emergence of order in complex systems far from equilibrium.

Capra also discusses the contributions of Heinz von Foerster (second-order cybernetics, which incorporates the observer into the system) and the limitations of early systems thinking, which he argues remained too mechanistic.

Chapter 4: The Logic of the Mind

This chapter is devoted to Gregory Bateson's revolutionary understanding of mind. Bateson defined mind as a necessary property of any system that processes information through feedback loops — not as a substance or an attribute of humans alone, but as a process immanent in living systems. His famous criteria for mind include: a mind is an aggregate of interacting parts; the interaction between parts is triggered by difference (information); the system requires collateral energy; the system has self-corrective (cybernetic) properties.

Capra shows how Bateson's ecology of mind dissolves the Cartesian dualism of mind and matter. If mind is a process of communication within a network, then it is present not only in organisms but also in ecosystems, societies, and even the planet as a whole. This sets the stage for the unification of biology and cognitive science that will follow in later chapters.

Part Three: The Pieces of the Puzzle

Chapter 5: Models of Self-Organization

Capra describes the major models of self-organization that emerged in the 1960s and 1970s. He begins with Ilya Prigogine's theory of dissipative structures, for which Prigogine won the 1977 Nobel Prize in Chemistry. A dissipative structure is an open system that maintains itself in a state far from thermodynamic equilibrium by continuously dissipating energy and matter into its environment. When such a system is pushed beyond a critical threshold, it may spontaneously reorganize into a new, more complex structure. This process — order through fluctuation — explains how order emerges from chaos in physical, chemical, and biological systems.

Capra illustrates with the Belousov-Zhabotinsky reaction, a chemical system that produces spectacular, self-organizing spiral patterns; Benard cells, where a fluid heated from below spontaneously forms hexagonal convection patterns; and the Oregonator, a mathematical model of oscillating chemical reactions. These examples demonstrate that self-organization is not a mysterious vital force but a fundamental property of complex systems.

Chapter 6: The Mathematics of Complexity

This chapter introduces the mathematical tools used to study complex systems. Capra covers chaos theory (the discovery that simple deterministic equations can produce apparently random behavior), fractal geometry (Benoit Mandelbrot's mathematics of irregular shapes), and strange attractors (the geometric structures that underlie chaotic dynamics).

Capra emphasizes that these mathematical developments represent a shift from quantity to quality. Fractal geometry, for example, provides a language for describing the irregular shapes of clouds, coastlines, trees, and lungs — patterns that Euclidean geometry could not capture. The Mandelbrot set, with its infinite complexity generated from a simple equation, becomes a metaphor for the relationship between simplicity and complexity in nature.

The chapter also covers the concept of "sensitive dependence on initial conditions" (the butterfly effect), Edward Lorenz's discovery that tiny differences in initial conditions can produce dramatically different outcomes in deterministic systems. Capra argues that chaos theory undermines the Laplacean dream of perfect prediction and opens science to a more nuanced understanding of causality.

Part Four: The Nature of Life

Chapter 7: A New Synthesis

This is the pivotal chapter where Capra brings together the pieces of the puzzle into a coherent framework. He introduces autopoiesis, the concept developed by Chilean biologists Humberto Maturana and Francisco Varela. Autopoiesis (from Greek: auto = self, poiesis = making) means "self-making." A living system produces and maintains itself through a network of processes in which every component participates in the production of other components. The cell membrane, for example, is produced by the cell, but also defines the boundary that makes the cell a distinct entity.

Capra argues that autopoiesis is the defining characteristic of life. An autopoietic network is:

1. Organizationally closed: Its internal structure is self-determining.
2. Structurally open: It continuously exchanges energy and matter with its environment.
3. Self-producing: The network's components participate in producing the network itself.

This framework resolves the ancient philosophical problem of the relationship between form and matter. The organization of a living system — its pattern of relationships — is what defines it, not the material substances of which it is composed. A living system continually replaces its components while maintaining its pattern of organization.

Chapter 8: Dissipative Structures

Capra returns to Prigogine's theory and deepens the analysis, showing how dissipative structures provide the physical foundation for the thermodynamic openness of living systems. Living systems are not closed systems that tend toward equilibrium and maximum entropy; they are open systems far from equilibrium that maintain their order by dissipating energy.

He explains how Prigogine's concept of "order through fluctuation" applies to biological evolution: mutations (fluctuations) are not merely random errors but potential sources of new order. When a system is pushed far from equilibrium, it may reach a bifurcation point where the system's future trajectory becomes unpredictable. At this point, small fluctuations can be amplified into macroscopic reorganizations — a process Capra sees as analogous to both biological evolution and creative human cognition.

Chapter 9: Self-Making (Autopoiesis)

Capra provides an in-depth examination of autopoiesis, focusing on Maturana and Varela's original formulations. He explores the concept of structural coupling — the process by which an autopoietic system interacts with its environment. The environment does not determine the system's structure; it only triggers changes that the system's own structure determines. This is the principle of "perturbation" rather than "instruction."

A key insight is that autopoietic systems are both autonomous and connected. The immune system, the nervous system, and ecological systems all exhibit autopoietic organization. The concept dissolves the traditional boundary between organism and environment: each is structurally coupled to the other, co-creating the domain of interaction.

Capra also addresses the relationship between autopoiesis and evolution. Evolution is not, as neo-Darwinism suggests, a matter of organisms adapting to a pre-existing environment. Instead, organisms and their environments co-evolve through mutual structural coupling. This perspective — developed by Varela as "natural drift" — offers a radical alternative to the competitive, adaptationist framework of mainstream evolutionary theory.

Chapter 10: The Unfolding of Life

Capra turns to development and evolution, examining how the autopoietic framework illuminates the processes by which life unfolds over time. He discusses the work of developmental biologists like Brian Goodwin and Stuart Kauffman, who argue that biological form is not merely a product of natural selection but also emerges from the intrinsic dynamics of complex systems.

Kauffman's concept of "order for free" — the spontaneous emergence of order in complex networks without natural selection — challenges the neo-Darwinian emphasis on random mutation and selection. Kauffman's Boolean network models show that complex systems exhibit spontaneous self-organization to a degree that cannot be explained by selection alone. Capra argues that evolution must be understood as a dance between self-organization and natural selection.

The chapter also covers the concept of morphogenetic fields (Rupert Sheldrake) — though Capra treats this more speculatively — and the work of biologists who study the self-organizing properties of developing embryos. The key insight: development is not the unfolding of a pre-written genetic program but an emergent, dynamic process in which the genes play an essential but not deterministic role.

Chapter 11: Bringing Forth a World

This chapter addresses cognition, drawing on Maturana and Varela's theory of enactive cognition. The central claim: living systems are cognitive systems, and the process of living is a process of cognition. This is the "Santiago theory of cognition" — Capra's name for the synthesis he builds from autopoiesis and the biology of cognition.

Cognition, in this framework, is not the representation of an external world but the enactment of a world through the organism's structural coupling with its environment. The nervous system does not process information about the world; it creates the world through its own organization. Each organism brings forth a world — its "umwelt" — that is specific to its sensorimotor structure.

Capra illustrates with the example of the visual system: the brain does not construct an internal picture of the external world. Instead, the visual system generates patterns of neuronal activity that correspond to the organism's interactions with its environment. Perception is not the passive reception of data but an active, constructive process. This framework dissolves the representational theory of mind and replaces it with an enactive, embodied theory of cognition.

Chapter 12: Knowing That We Know

The final chapter examines self-awareness and the nature of consciousness. If cognition is a property of all living systems, what distinguishes human self-awareness? Capra argues that the capacity for self-reflection — "knowing that we know" — emerges in human linguistic communities. Language, in Maturana's framework, is not a tool for transmitting information but a domain of consensual coordination of actions.

Capra distinguishes between:

• First-order cognition: The basic cognitive processes of all living organisms.
• Second-order cognition (self-awareness): The recursive capacity to reflect on one's own cognition, made possible by language.

He draws on Bateson's concept of "deutero-learning" (learning to learn) and on the Buddhist tradition's analysis of the self as a mental construction. The self, Capra argues, is not a thing but a process — a recursive pattern of self-reference that emerges in language. This dissolves both the Cartesian ego and the reductionist denial of consciousness.

The chapter ends with a discussion of spirituality. Capra argues that the systemic understanding of life leads naturally to a spiritual dimension — not in the sense of supernatural belief, but as a direct experience of the interconnectedness of all phenomena. He quotes Bateson: "The pattern which connects is a meta-pattern."

Epilogue: Ecological Literacy

Capra applies the systemic understanding of life to the practical challenge of creating sustainable societies. Ecological literacy, he argues, means understanding the principles of organization that ecosystems have evolved over billions of years — principles that human societies must learn to emulate.

Key principles of ecological literacy include:

• Interdependence: All members of an ecosystem are interconnected in a web of relationships.
• Cyclical flow: In ecosystems, waste is constantly recycled; there is no such thing as waste in nature.
• Flexibility: Ecosystems maintain stability through flexibility and diversity, not through rigidity.
• Cooperation: Partnership and cooperation are at least as important as competition in ecosystem dynamics.
• Emergence: Properties of the whole emerge from the interaction of the parts.

Capra argues that designing sustainable human communities requires applying these ecological principles to economics, technology, and social organization. The epilogue is both a summary of the book's scientific argument and a call to action.

Appendix: Bateson Revisited

Capra adds a brief appendix that revisits Gregory Bateson's contributions in light of the framework developed in the book. He clarifies how his own synthesis both builds on and differs from Bateson's ecology of mind, particularly in the relationship between mind, matter, and evolution.

Reading Guide

The Web of Life can be read in three different paths depending on the reader's background:

For the general reader (no prior background in systems theory): Read chapters 1-4 for the cultural and historical context, then chapters 7 and 9-11 for the core argument about life and cognition. The more technical chapters (5-6, 8) can be skimmed without losing the main thread.

For scientists and students with background in biology or physics: Read the book straight through. The mathematics of complexity (chapters 5-6) and the thermodynamics of dissipative structures (chapter 8) will be accessible and rewarding.

For environmentalists and educators: Focus on chapter 1 (deep ecology), chapters 2-3 (systems thinking), chapters 9-11 (life, cognition, and their implications), and the epilogue on ecological literacy.

The book has aged well in its core argument — the convergence of systems thinking, complexity theory, and ecology — though some of the specific scientific examples (particularly in chaos theory and molecular biology) have been superseded by later research. The chapters on cognitive science (11-12) remain particularly insightful and anticipate later developments in embodied cognition and enactivism.

1. Historical & Cultural Context

The Web of Life was published in 1996, at a unique moment in intellectual history. The Cold War had ended, the internet was emerging as a transformative technology, and the Rio Earth Summit (1992) had brought environmental issues to global attention. In science, chaos theory and complexity were fashionable, molecular biology was booming, and the Human Genome Project was underway. Capra's book arrived as a counterweight to the triumphant reductionism of the genomic age — an attempt to reassert the importance of holistic, systemic thinking at the very moment when biology was becoming ever more molecular. The book also appeared in the wake of the "science wars" of the mid-1990s, which pitted scientific realists against postmodern constructivists. Capra's project of synthesizing science and values was itself a contribution to that debate.

2. Author Background & Positioning

Fritjof Capra (born 1939, Vienna, Austria) earned his PhD in theoretical physics from the University of Vienna in 1966. He conducted postdoctoral research in particle physics at the University of Paris and the University of California, Santa Cruz. His first book, The Tao of Physics (1975), became an international bestseller and established him as a leading voice in the dialogue between science and spirituality. The Turning Point (1982) expanded his critique to medicine, economics, and society. By the time of The Web of Life, Capra had positioned himself as a systems theorist and public intellectual, moving beyond physics into biology and ecology. He co-founded the Center for Ecoliteracy in Berkeley, California (1995), which applies systems thinking to education. His position is distinctive: a physicist by training who has become a critic of reductionist physics and an advocate for a biology-centered paradigm. This outsider-insider status gives him credibility with general readers while drawing skepticism from specialists in each field he touches.

3. Core Argument & Thesis

The book's thesis can be stated simply: the living world is organized as networks of relationships, and understanding life requires a corresponding shift in our conceptual framework — from substances to patterns, from parts to wholes, from analysis to synthesis. Capra argues that four intellectual streams converge to form the new paradigm: systems thinking (Bertalanffy, Bareson), the thermodynamics of far-from-equilibrium systems (Prigogine), the theory of autopoiesis (Maturana and Varela), and complexity mathematics (chaos theory, fractals). When synthesized, these streams yield a unified understanding of life as self-organizing, autopoietic, cognitive, and fundamentally interconnected. The thesis is both scientific and philosophical: it claims to explain what life is while simultaneously arguing that the mechanistic worldview that enabled the scientific revolution is no longer adequate for the scientific challenges of our time.

4. Strengths

Intellectual synthesis. Capra's greatest achievement is bringing together disparate scientific developments — from Prigogine's thermodynamics to Maturana and Varela's biology of cognition — into a coherent narrative. No other book of the period attempted such a comprehensive synthesis.

Accessibility. The book translates complex ideas from thermodynamics, nonlinear dynamics, and neurobiology into clear, equation-free prose. Capra's writing style is engaging and metaphorical without being imprecise.

Historical depth. The historical chapters (2-4) on the development of systems thinking and cybernetics are among the best concise treatments available of these intellectual movements.

Concept of autopoiesis. Capra's exposition of Maturana and Varela's work is the book's most valuable contribution. He makes the radical implications of autopoiesis clear without losing the reader in the technical details of the original publications.

Practical relevance. The epilogue on ecological literacy has influenced environmental education worldwide. Capra's "principles of ecology" are taught in schools, universities, and sustainability programs.

5. Weaknesses

Overreach. The book claims to present the new understanding of living systems, but it often reads as a new understanding — one of several competing frameworks. Capra's synthesis is not universally accepted in any of the fields he discusses.

Selective engagement. Capra engages almost exclusively with scientists who support his thesis. Critics of autopoiesis, dissenters from Prigogine's framework, and defenders of neo-Darwinian orthodoxy are mentioned only as straw men.

Lack of empirical detail. The book is almost entirely conceptual; it provides very little experimental evidence or discussion of how the framework could be tested empirically. As H. Eugene Stanley wrote in New Scientist (December 7, 1996): "Capra confuses understanding with metaphor."

Date of the science. Some of the specific scientific content is now dated. The chapters on chaos theory and fractals captured the excitement of the 1990s but do not reflect how these fields developed in subsequent decades.

Sparse treatment of genetics and molecular biology. Given that molecular biology was the dominant paradigm in the life sciences at the time, Capra's dismissal of it as "reductionist" without serious engagement is a significant gap.

6. Named Critics & Objections

H. Eugene Stanley, New Scientist (December 7, 1996). Stanley, a prominent physicist at Boston University, wrote that "the half-month I have spent reading The Web of Life has not brought me any closer to answering Schrodinger's question 'What Is Life?'" He argued that Capra "confuses understanding with metaphor" and that the book could "fuel the antiscience forces who would love to believe that many of the ills of the world are brought on by a reductionist world view." While praising the historical account of feedback mechanisms, Stanley concluded that "the overriding impression given by the book is its attempt to indict reductionist science."

Kirkus Reviews (September 1996). The anonymous Kirkus review described Capra as placing "modern biology and ecology under his revisionist scrutiny" and noted the book's premise that "earlier schools of science falsely attempted to force their subjects into mechanistic, easily quantifiable models." The review was cautiously positive but noted that Capra's claims were broader than the evidence he presented.

Jeremy C. Ahouse, ResearchGate (1998). Ahouse, a biologist, published a critical review/essay arguing that "Capra fails to show that his 'Mathematics of Complexity' offers any valuable insights about living systems." He characterized Capra's treatment of fractal geometry as "excessively two-dimensional" and argued that the book "digresses into complex numbers as they facilitate the 2D views of fractals" without demonstrating their relevance to living systems.

I.M. Oderberg, Sunrise magazine / Theosophical Society (1997). Oderberg offered a spiritual critique from a theosophical perspective, arguing that Capra's materialism — even his holistic materialism — still failed to account for the spiritual dimensions of existence. He noted that "spectacular discoveries in astrophysics and the theories of some physicists suggesting the universality of consciousness would seem to counterpoise Capra's remarks."

Mainstream biology establishment. While no single named biologist issued a definitive critique, the broader biological community largely ignored autopoiesis and the Santiago theory of cognition. Mainstream biology continues to operate within a molecular-genetic framework that has little room for Capra's systemic synthesis.

Scientific materialists. Materialist philosophers and scientists (such as Daniel Dennett, whose Consciousness Explained was published in 1991) would object that Capra's attribution of cognition to all living systems is panpsychism in scientific clothing — a philosophical position rather than an empirical finding.

7. Impact & Influence

The Web of Life has had a significant but diffuse impact. It sold well internationally, was translated into at least 15 languages, and became a standard reference in environmental studies programs. It influenced the development of ecological education through the Center for Ecoliteracy, which Capra co-founded and which by 2025 had trained thousands of educators in systems-based sustainability curricula. The book's "principles of ecology" — interdependence, cyclical flow, flexibility, diversity, emergence — have been adopted by organizations like the Buckminster Fuller Institute and the Schumacher College. In academic circles, the book is more often cited in environmental studies, education, and the humanities than in mainstream biology. The concept of "ecological literacy" has entered the vocabulary of educational reform and appears in UNESCO sustainability frameworks.

Capra's synthesis anticipated later developments in embodied cognition — particularly the work of researchers like Evan Thompson (The Embodied Mind, 1991, revised 2016) and Alva Noe (Action in Perception, 2004), who developed enactive cognitive science into a robust empirical program — and network science, which has become a dominant paradigm across physics, biology, and the social sciences. However, the book's core ambition — to displace the molecular-genetic paradigm in biology with an autopoietic-systems paradigm — has not been realized. The systems biology that emerged in the 2000s is data-driven and computational, closer to engineering than to the conceptual autopoiesis that Capra championed.

8. Academic & Critical Reception

The book was reviewed widely in the popular press but received limited attention in peer-reviewed scientific journals. It was reviewed in New Scientist (by H. Eugene Stanley), Publishers Weekly, Library Journal, and various environmental and alternative periodicals. Some philosophy of science journals engaged with its arguments — particularly the British Journal for the Philosophy of Science, which published a discussion of Capra's claims about autopoiesis and cognition. Mainstream biology journals largely ignored it, a silence that Capra's supporters interpret as resistance to paradigm change and his critics interpret as appropriate disciplinary boundary maintenance.

Among those who engaged with it, the reception was polarized: enthusiasts praised its vision and synthesis; critics argued that it substituted metaphor for mechanism. The book's legacy is therefore stronger in applied fields (ecological design, sustainability education, organizational theory) than in the core biological sciences, where the molecular-genetic paradigm remains dominant. In the two decades since publication, the systems biology approach has gained substantial ground — but it is a data-driven, computational systems biology that uses high-throughput genomics and mathematical modeling, quite different from Capra's conceptual autopoietic framework. As systems biologist Uri Alon wrote in 2019, the field "has moved from qualitative networks to quantitative models that can be tested experimentally" — a trajectory Capra did not anticipate.

10. Practical Applications

Despite its lack of mainstream scientific acceptance, the book has found practical applications in ecological design, sustainability education, and organizational theory. The Center for Ecoliteracy applies Capra's framework to K-12 education, teaching students the principles of ecosystems as a foundation for understanding sustainability. The book's emphasis on networks and self-organization has influenced organizational theorists who apply living-systems metaphors to business management and social movements. In architecture and design, Capra's principles have informed the growing field of biomimicry, though practitioners more often cite Janine Benyus's Biomimicry (1997) directly.

11. Final Evaluation

The Web of Life is a work of grand synthesis — ambitious, eloquent, and provocative. It succeeds magnificently as a popular introduction to systems thinking and the philosophy of biology. It fails, in the judgment of most working biologists, as a scientific contribution to the understanding of life. The gap between these two assessments is the book's central tension. Capra writes as a philosopher-synthesizer rather than a bench scientist, and his strength — the ability to see connections across disciplines — is also his weakness: the connections are sometimes more metaphorical than causal. Two decades on, the book's reputation has settled into an honorable niche: it is not the paradigm-shifting work Capra hoped for, but it remains one of the best single-volume introductions to the systemic view of life, a provocation to reductionist orthodoxy, and a valuable resource for anyone who wants to understand why some scientists believe that the whole is indeed more than the sum of its parts.
