Combining principles of individual rational choice with a sociological conception of collective action, James Coleman recasts social theory in a bold new way. The result is a landmark in sociological theory, capable of describing both stability and change in social systems. This book provides for the first time a sound theoretical foundation for linking the behavior of individuals to organizational behavior and then to society as a whole. The power of the theory is especially apparent when Coleman analyzes corporate actors, (...) such as large corporations and trade unions. He examines the creation of these institutions, collective decision making, and the processes through which authority is revoked in revolts and revolutions. Coleman discusses the problems of holding institutions responsible for their actions as well as their incompatibility with the family. He also provides a simple mathematical analysis corresponding to and carrying further the verbal formulations of the theory. Finally, he generates research techniques that will permit quantitative testing of the theory. From a simple, unified conceptual structure Coleman derives, through elegant chains of reasoning, an encompassing theory of society. It promises to be the most important contribution to social theory since the publication of Talcott Parsons' Structure of Social Action in 1936. (shrink)

Donald Olding Hebb, referred to by American Psychologist as one of "the 20th century's most eminent and influential theorists in the realm of brain function and behavior," contributes greatly to the understanding of mind and thought in Essays on Mind. His objective was to learn about thought which he considered "the central problem of psychology -- but also, not less important, to learn how to think clearly about thought, which is philosophy." The volume is written for advanced undergraduates, graduates, professionals, (...) and lay people interested in or studying the mind. Hebb offers an increased understanding of the mind from a biological perspective that affects long-standing philosophical and psychological problems. "Psychology and Philosophy were divorced some time ago but, like other divorced couples, they still have problems in common," writes Hebb. The first three chapters establish the methodological and philosophical basis for his biologically centered theory of behavior, including the evolution of the mind, nature versus nurture, the origination and status of cell-assembly theory, and infant thought and language development. He concludes with a discussion of the workings of scientific thought from a practical rather than theoretical perspective. (shrink)

Reprint of the original, first published in 1869.

In this chapter I review empirical studies directly testing the hypotheses of my 1973 paper "The Strength of Weak Ties" (hereafter "SWT") and work that elaborates those hypotheses theoretically or uses them to suggest new empirical research not discussed in my original formulation. Along the way, I will reconsider various aspects of the theoretical argument, attempt to plug some holes, and broaden its base.

A mathematical theory is proposed and exemplified, which covers an extended class of black boxes. Every kind of stimulus and response is pictured by a channel connecting the box with its environment. The input-output relation is given by a postulate schema according to which the response is, in general, a nonlinear functional of the input. Several examples are worked out: the perfectly transmitting box, the damping box, and the amplifying box. The theory is shown to be (a) an extension of (...) the S-matrix theory and the accompanying channel picture as developed in microphysics; (b) abstract and applicable to any problem involving the transactions of a system (physical, biological, social, etc.) with its milieu; (c) superficial, because unconcerned with either the structure of the box or the nature of the stimuli and responses. The motive for building the theory was to show the capabilities and limitations of the phenomenological approach. (shrink)

Mechanisms in a theory are defined here as bits of theory about entities at a different level (e.g., individuals) than the main entities being theorized about (e.g., groups), which serve to make the higher-level theory more supple, more accurate, or more general. The criterion for whether it is worthwhile to theorize at lower levels is whether it makes the theory at the higher levels better, not whether lower-level theorizing is philosophically necessary. The higher-level theory can be made better by mechanisms (...) known to be inadequate in the discipline dealing with the lower level. Conditions for the usefulness of lower-level theorizing are proposed, with many examples from various social and physical sciences. (shrink)

Stuart Kauffman here presents a brilliant new paradigm for evolutionary biology, one that extends the basic concepts of Darwinian evolution to accommodate recent findings and perspectives from the fields of biology, physics, chemistry and mathematics. The book drives to the heart of the exciting debate on the origins of life and maintenance of order in complex biological systems. It focuses on the concept of self-organization: the spontaneous emergence of order widely observed throughout nature. Kauffman here argues that self-organization plays an (...) important role in the emergence of life itself and may play as fundamental a role in shaping life's subsequent evolution as does the Darwinian process of natural selection. Yet until now no systematic effort has been made to incorporate the concept of self-organization into evolutionary theory. The construction requirements which permit complex systems to adapt remain poorly understood, as is the extent to which selection itself can yield systems able to adapt more successfully. This book explores these themes. It shows how complex systems, contrary to expectations, can spontaneously exhibit stunning degrees of order, and how this order, in turn, is essential for understanding the emergence and development of life on Earth. Topics include the new biotechnology of applied molecular evolution, with its important implications for developing new drugs and vaccines; the balance between order and chaos observed in many naturally occurring systems; new insights concerning the predictive power of statistical mechanics in biology; and other major issues. Indeed, the approaches investigated here may prove to be the new center around which biologicalscience itself will evolve. The work is written for all those interested in the cutting edge of research in the life sciences. (shrink)
