Roger Lewin sets out to better understand the notion of emergence, and, more broadly, its relationship to the science of Complexity. Whether or not it is intentional, Lewin's approach is itself a sort-of exercise in cultivating emergence. In trying to tease out the more subtle aspects and important ramifications of Complexity theory and science, Lewin hopes to uncover heretofore unrealized understandings.
As an introduction to Complexity Lewin's work successfully posits different thinkers against one another. In-so-doing he simulates a focused dialogue for the uninitiated that at once examines the common ground and differentiation in thinking about complex systems. Along the way aspects of evolution and self-organization within systems are given a critical examination. If, as many scientists within the work suggest (and Lewin seems to be sympathetic towards), there are certain attractors of order within complex systems, then evolution will favor certain outcomes. If true, the implications of this force a re-imagination of Darwin's theory and might demand a re-examination of our interactions with the world. The uncertainty of emergence is perhaps the most tricky, yet the most potentially fruitful aspect, of Complexity thought.
At the very least, notions of Complexity thinking suggest reflection surrounding notions of equilibria in nature. If it is less the components of a system, and more the interactions between these pieces, that give a system its identity, then evolution and creative novelty are both drivers and resultants of complex systems. Looking towards relationships first, as Serres and Whitehead do, means re-thinking our approaches across disciplines; scientific or otherwise.
