Synthesized answer
The passages do not explicitly define "complex" systems as having "many different components operating at many different temporal and spatial scales," nor do they directly contrast this with "merely complicated" systems. Instead, Lawhead distinguishes "complex/simple" from "complicated/simplistic," stating that all science is "complicated in the sense of being difficult, multi-faceted, and messy," and that there are "no simplistic systems in nature" [1][4]. The key differentiation is that complexity is a "dynamical fact" about how a system behaves—specifically, how many useful perspectives or compressions can be adopted to predict its time-evolution—rather than a fact about its composition or number of parts [3].
The distinction is crucial for scientific inquiry because it cuts across the traditional physical/social science divide, offering a new way to categorize problems [2][5]. Lawhead argues that this "complex-systems sciences" versus "simple-systems sciences" distinction helps unify branches of science that study systems with many useful predictive perspectives (like climate or economics) versus those with fewer (like a free photon) [3][5]. However, the passages do not…

ly) difficult , and no branch of contemporary science is simplistic in the sense of being facile, superficial, or easy . In opposing complex systems to simple systems, then, I am not claiming that some branches of science are “hard” and some are “soft” in virtue of being more or less rigorous—indeed, the hard/soft science distinction (which roughly parallels the physical/social science distinction, at least most of the time) is precisely the conceptual carving that I’m suggesting we ought to move beyond. There are no simplistic sciences: all science is complicated in the sense of being…
← Chapter 1 Lightning in a Bottle by Jonathan Lawhead Chapter 2 Chapter 3 → 2042362 Lightning in a Bottle — Chapter 2 Jonathan Lawhead Chapter Two What's the Significance of Complexity? 2.0 Introduction and Overview In Chapter One , I presented a general theory about the nature of the scientific project, and argued that this general theory suggests a natural way of thinking about the relationship between (and underlying unity of) the different branches of science. This way of looking at science is instructive but (as I said), doing abstract philosophy of science is not really my goal here.…
ad of me is just that the system containing me can be usefully carved up in more ways than the system containing my cat. My brain is more complex than my cat’s brain in virtue of there being more ways to compress systems containing my brain such that the time-evolution of those states can be reliably predicted than there are ways to compress systems containing my cat’s brain such that the same is true. The global climate today is more complex than was the global climate 1 billion years ago in virtue of there being more ways to usefully carve up the climate system today than there were 1…
need to articulate what exactly makes a system complex, and examine the structure of complex systems theories generally. Just as in Chapter One , my focus here will be primarily on exploring the actual practice of contemporary, working science: I’m interested in what climate scientists, economists, and statistical physicists (as well as others working in the branches of science primarily concerned with predicting the behavior of complex systems) can learn from one another, rather than in giving a priori pronouncements on the structure of these branches of science. With that goal in mind, we…
verall. Chapters Two and Three taken together are primarily a contribution to the foundations of complex-systems theory. Building on the account of science from Chapter One , I argue that the traditional bifurcation of science into physical and social sciences is, at least sometimes, misleading. I suggest that we should also see some scientific problems in terms of a distinction that cuts across the physical/social science division: the distinction between complex-systems sciences and simple-systems sciences. After reviewing some of the attempts to define "complexity" in the (relatively…
More questions about this book
- How does Lawhead's concept of "dynamical complexity" specifically address the limitations of existing complexity definitions by providing a "physical interpretation" for physical and social systems, rather than just "information-theoretic objects"?
- If climatology is a "paradigmatic complex systems science," how might the dissertation's title, "Lightning in a Bottle," metaphorically capture the inherent challenges or ambitions in understanding and modeling such a system?
- The text suggests "dynamical complexity" can inform "theories, explanation, and lawhood" in the philosophy of science. How might understanding the "dynamics shaped by the interaction of many different components" fundamentally change our approach to constructing or evaluating scientific "explanations"?
- Given the statement that "climate model families are significantly more diverse" than in other sciences, what specific implications does this diversity have for validating climate science models and building trust in their projections, especially concerning foundational questions about reliability?
