Can human social evolution be described in terms common to other sciences, most specifically, as an energy process? The Eighth Day reflects a conviction that the human trajectory, for all its uniqueness and indeterminism, will never be satisfactorily understood until it is framed in dynamics that are common to all of nature. The problem in doing this, however, lies in ourselves. The major social theories have failed to treat human social evolution as a component of broader natural processes.

The Eighth Day argues that the energy process provides a basis for explaining, comparing, and measuring complex social evolution. Using traditional ecological energy flow studies as background, society is conceived as a self-organization of energy. This perspective enables Adams to analyze society in term of the natural selection of self-organizing energy forms and the trigger processes basic to it. Domestication, civilization, socioeconomic development, and the regulation of contemporary industrial nation-states serve to illustrate the approach. A principal aim is to explore the limitation that energy process imposes on human social evolution as well as to clarify the alternatives that it allows.

Richly informed by contemporary anthropological historicism, sociobiology, and Marxism, The Eighth Day avoids simple reductionism and denies facile ideological categorization. Adams builds on work in nonequilibrium thermodynamics and theoretical biology and brings three decades of his own work to an analysis of human society that demands an extreme materialism in which human thought and action find a central place.

The contributions to this volume attempt to apply different aspects of Ilya Prigogine's Nobel-prize-winning work on dissipative structures to nonchemical systems as a way of linking the natural and social sciences. They address both the mathematical methods for description of pattern and form as they evolve in biological systems and the mechanisms of the evolution of social systems, containing many variables responding to subjective, qualitative stimuli.

The mathematical modeling of human systems, especially those far from thermodynamic equilibrium, must involve both chance and determinism, aspects both quantitative and qualitative. Such systems (and the physical states of matter which they resemble) are referred to as self-organized or dissipative structures in order to emphasize their dependence on the flows of matter and energy to and from their surroundings. Some such systems evolve along lines of inevitable change, but there occur instances of choice, or bifurcation, when chance is an important factor in the qualitative modification of structure. Such systems suggest that evolution is not a system moving toward equilibrium but instead is one which most aptly evokes the patterns of the living world.

The volume is truly interdisciplinary and should appeal to researchers in both the physical and social sciences. Based on a workshop on dissipative structures held in 1978 at the University of Texas, contributors include Prigogine, A. G. Wilson, Andre de Palma, D. Kahn, J. L. Deneubourgh, J. W. Stucki, Richard N. Adams, and Erick Jantsch.

The papers presented include Allen, "Self-Organization in the Urban System"; Robert Herman, "Remarks on Traffic Flow Theories and the Characterization of Traffic in Cities"; W. H. Zurek and Schieve, "Nucleation Paradigm: Survival Threshold in Population Dynamics"; De Palma et al., "Boolean Equations with Temporal Delays"; Nicholas Georgescu-Roegin, "Energy Analysis and Technology Assessment"; Magoroh Maruyama, "Four Different Causal Meta-types in Biological and Social Sciences"; and Jantsch, "From Self-Reference to Self-Transcendence: The Evolution of Self-Organization Dynamics."

Using Ukraine as a case-in-point, Svitlana Krasynska engages diverse bodies of literature and rich empirical data to reveal the vital role and unique potential of below-the-radar civic engagement in contexts where informal practices abound—a phenomenon largely neglected by scholars of civil society who traditionally focus on formal civic organizations.

Civil society in Eastern Europe has long been labeled weak based on a general lack of citizen participation in formal civil society organizations—a key criterion for assessing civic engagement in comparative studies. However, such assessment of civil society fails to recognize the role and impact of informal civic engagement in contexts where informality permeates economic, political, and social spheres. Ukraine offers a valuable counterargument of the importance of informal civil society in Eastern Europe, especially in the post-Soviet countries.

Krasynska convincingly shows that informality constitutes an essential component of civil society, shaping popular approaches to addressing social, economic, and political issues. The trailblazing findings in Below the Radar will be of interest to scholars of democratization, informality, and area studies, and they will aid development practitioners and policy makers in determining a more effective approach to helping fledgling democracies around the world.
