  • Paradigm for the Sociology of Knowledge 1945
    1 Paradigm for the Sociology of Knowledge 1945 The last generation has witnessed the emergence of a special field of sociological inquiry: the sociology of knowledge (Wissenssoziologie). The term “knowledge” must be interpreted very broadly indeed, since studies in this area have dealt with virtually the entire gamut of cultural products (ideas, ideologies, juristic and ethical beliefs, philosophy, science, tech­ nology). But whatever the conception of knowledge, the orientation of this discipline remains largely the same: it is primarily concerned with the relations between knowledge and other existential factors in the society or culture. General and even vague as this formulation of the central purpose may be, a more specific statement will not serve to include the diverse approaches which have been developed. Manifestly, then, the sociology of knowledge is concerned with problems that have had a long history. So much is this the case, that the discipline has found its first historian, Ernst Gruenwald.1 But our primary concern is not with the many antecedents of current theories. There are indeed few present-day observations which have not found previous expression in suggestive aperçus. King Henry IV was being reminded that “Thy wish was father, Harry, to that thought” only a few years before Bacon was writing that “The human understanding is no dry light but receives an Originally published as “Sociology of Knowledge,” in Georges Gurvitch and Wil­ bert E.

  • Crossing the Boundaries? Dynamics of Contention Viewed from the Angle of a Comparative Historian
    IRSH 49 (2004), pp. 122–131 DOI: 10.1017/S002085900300141X # 2004 Internationaal Instituut voor Sociale Geschiedenis Crossing the Boundaries? Dynamics of Contention Viewed from the Angle of a Comparative Historian Thomas Welskopp Comparative social history is still grappling with the problems raised in the debate about history’s ‘‘cultural turn’’. And while a new ‘‘social turn’’ seems imminent at the moment, this means a new departure into an actor- oriented analysis of institutions (including social movements and all forms of contentious politics) beyond the ‘‘cultural turn’’, incorporating a host of compelling insights into the cultural constitution of social reality – and not a return to the old simplistic views of the ‘‘modernization era’’. With their undoubtedly quite innovative book, Dynamics of Conten- tion, Doug McAdam, Sidney Tarrow, and Charles Tilly move within a slightly different discourse – that within the macrosociological study of collective action and social movements – in order to revolutionize what they call the ‘‘classical agenda’’ in comparative sociology and political studies. Saying this, I do not intend to redraw disciplinary boundaries between history and sociology. My argument is rather that Dynamics of Contention both challenges comparative history and presents an invitation – a suggestion to solve many of the problems that had come up during the debate over the ‘‘cultural turn’’ in history. This is the more so as the authors themselves explicitly relate to history in three respects. First, they want their work to be recognized as historical study. This is to be granted by any means. Second, the authors openly intend to bridge the gap between sociological and historical comparison.

  • The Critique of Real Abstraction: from the Critical Theory of Society to the Critique of Political Economy and Back Again
    The Critique of Real Abstraction: from the Critical Theory of Society to the Critique of Political Economy and Back Again Chris O’Kane John Jay, CUNY [email protected] There has been a renewed engagement with the idea of real abstraction in recent years. Scholars associated with the New Reading of Marx, such as Moishe Postone, Chris Arthur, Michael Heinrich, Patrick Murray, Riccardo Bellofiore and others,1 have employed the idea in their important reconstructions of Marx’s critique of political economy. Alberto Toscano, Endnotes, Jason W. Moore and others have utilized and extended these theorizations to concieve of race, gender, and nature as real abstractions. Both the New Reading and these new theories of real abstraction have provided invaluable work; the former in systematizing Marx’s inconsistent and unfinished theory of value as a theory of the abstract social domination of capital accumulation and reproduction; the latter in supplementing such a theory. Yet their exclusive focus on real abstraction in relation to the critique of political economy means that the critical marxian theories of real abstraction -- developed by Alfred Sohn- Rethel, Theodor W. Adorno and Henri Lefebvre -- have been mostly bypassed by the latter and have largely served as the object of trenchant criticism for their insufficient grasp of Marx’s theory of value by the former. Consequently these new readings and new theories of real abstraction elide important aspects of Sohn-Rethel, Adorno and Lefebvre’s critiques of real abstraction; which sought to develop Marx’s critique of political economy into objective-subjective critical theories of the reproduction of capitalist society.2 However, two recent works by 1 Moishe Postone’s interpretation of real abstraction will be discussed below.

  • Philosophy of Technology ‘Un-Disciplined’
    Philosophy of Technology ‘Un-Disciplined’ William J. Davis III Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Science and Technology Studies James H. Collier, Chair Joseph C. Pitt Richard F. Hirsh Ellsworth R. Fuhrman 25 March 2016 Blacksburg, Virginia Keywords: Philosophy of Technology, Postphenomenology, Posthumanism, Science and Technology Studies Copyright 2016, William J. Davis III Philosophy of Technology ‘Un-Disciplined’ William J. Davis III Abstract Philosophy of technology (PoT) analyzes the nature of technology, its significance and consequences, and its mediation of human experiences of the world. Classical philosophers of technology describe mechanization as alienating: Technology causes humans to lose their connection with the natural world. Tehno-rationality replaces critical engagement and creativity. Failing to comprehend the essence/nature of Technology, and its consequences, portends disastrous social, political, and economic consequences. Such perspectives, however, neglect individual experiences of technologies. Filling that lacuna, contemporary philosophers of technology challenge the sweeping determinism of their intellectual forerunners and investigate how specific technologies mediate particular human experiences. Their descriptive prowess, however, lacks the normative engagement of classical PoT, and they emphasize micro effects of technologies to the detriment of macro implications. This dissertation describes an “un-disciplined” philosophy of technology (UPoT) that unites the macro and micro perspectives by providing narratives of human-technology symbiosis and co-development. Un-disciplined philosophers of technology present posthuman and transhuman perspectives that emphasize the symbiotic relationships between humans and technology. Thus, they deny disciplined philosophy’s first critical maneuver: define and demarcate.

  • Some Notes on Theories of Technology, Society and Innovation Systems for S&T Policy Studies
    1 Some notes on theories of Technology, Society and Innovation Systems for S&T policy studies Mónica Salazar-Acosta and Adam Holbrook CPROST Report 08-02 2 3 Some notes on theories of technology, society and innovation systems for science and technology policy studies Mónica Salazar-Acosta and Adam Holbrook, with editorial comments by Glenda Shaw-Garlock CENTRE FOR POLICY RESEARCH ON SCIENCE AND TECHNOLOGY SIMON FRASER UNIVERSITY Vancouver BC Report 08-02 Introduction Does technology shape society, or does society influence our technological choices? Is technological determinism a theory of society or a theory of technology? The debate on Science, Technology and Society (STS) studies has been animated by two opposite views on technology: one that affirms that technology shapes society, and the other that society shapes technology. The former, is commonly associated with the notion of technological determinism; while the latter could be labeled ‘social shaping of technology’ which covers various approaches, such as social constructivism and actor-network theory. Neither provides an overall view: one looks at the forest and the other at the trees, but both have failed to give us a comprehensive view of technological change and the major forces driving social change. What follows is an examination of technological determinism – the shaping of society by technology - and the influence of society on the evolution of technology . It does not pretend to be exhaustive or representative of the most recent scholarship on the subject. A good, recent,

  • Feminist Theories of Technology
    Cambridge Journal of Economics 2010, 34, 143–152 doi:10.1093/cje/ben057 Advance Access publication 8 January 2009 Feminist theories of technology Judy Wajcman* Feminist theories of technology have come a long way over the last quarter of a century. The expanding engagement at the intersection of feminist scholarship and Downloaded from science and technology studies (STS) has enriched both fields immeasurably, and I will largely focus my reflections on the literature associated with these sites. I begin by highlighting the continuities as well as the differences between contemporary and earlier feminist debates on technology. Current approaches focus on the mutual shaping of gender and technology, in which technology is conceptualised as both a source and consequence of gender relations. In avoiding both technological cje.oxfordjournals.org determinism and gender essentialism, such theories emphasise that the gender- technology relationship is fluid and situated. These deliberations highlight how processes of technical change can influence gender power relations. A feminist politics of technology is thus key to achieving gender equality.

Introduction This article provides an overview of the various approaches to conceptualising the link between gender and technology, both past and present. In turning to this task, I should emphasise that feminist discussions have always taken diverse and overlapping forms. While standard accounts of feminist thought tend to present liberal, socialist and post- modern feminisms as distinct perspectives, in reality they did not develop as independent strands or in a simple chronological order.

  • Diffusion Theory & Instructional Technology
    Diffusion Theory & Instructional Technology Diffusion Theory and Instructional Technology Daniel W. Surry University of Southern Mississippi Paper presented at the Annual Conference of the Association for Educational Communications and Technology (AECT), Albuquerque, New Mexico February 12 - 15, 1997. [email protected] © 1997, DAN SURRY Abstract This paper discusses how the theories of innovation diffusion have been incorporated into the field of instructional technology. The paper begins with a brief description of general diffusion theory that includes mention of the four most commonly discussed diffusion theories. Following the discussion of general diffusion theory, the author describes how general diffusion theories have been used to form diffusion theories specific to the field of instructional technology. The paper states that the two màjor categories of IT-related diffusion theory are Systemic Change Theories and Product Utilization Theories. Examples of each category are provided. The paper identifies and describes two opposing philosophical views of technology: Determinism and Instrumentalism. The author uses the two philosophies of technology to create two subcategories of IT-related diffusion theory: Developer Based Theories and Adopter Based Theories. Examples of both subcategories are provided.The author contends that Developer àBased Theories are flawed in that they overstate the role of technological superiority in the diffusion process. DIFFUSION THEORY AND INSTRUCTIONAL TECHNOLOGY The purpose of this paper is to describe how the theory of innovation diffusion has been incorporated http://www.gsu.edu/%7Ewwwitr/docs/diffusion/ (1 of 14) [11/22/04 8:09:31 AM] Diffusion Theory & Instructional Technology into the field of instructional technology.
