This article looks at the increasing prominence of bioterrorist threat scenarios in recent US foreign policy. Germ warfare, it argues, is being depicted as the paradigmatic threat of the post-Cold War era, not only because of its affinity for cross-border movement but also because it blurs the lines between deliberate attack and spontaneous natural catastrophe. The article looks at the possible implications of this move for understandings of war, strategy and public health. It also seeks to contextualize the US’s growing (...) military interest in biodefence research within the commercial strategies of the biotech and pharmaceutical industries. In its methodology, the article weaves together elements from defence literature, scientific perspectives on infectious disease, catastrophe theory and political economy. The conceptual underpinnings of the strategy of pre-emptive warfare, it argues, lie as much in the theory of biological emergence as in official US defence strategy. (shrink)

The abrupt climate change thesis suggests that climate passes through threshold transitions, after which change is sudden, runaway and unstoppable. This concurs with recent themes in complexity studies. Data from ice cores indicates that major shifts in global climate regimes have occurred in as little as a decade, and that for most of the span of human existence the climate has oscillated much more violently than it has over the last 10,000 years. This evidence presents enormous challenges for international climate (...) change negotiation and regulation, which has thus far focused on gradual change. It is argued that existing social theoretic engagements with physical agency are insufficiently geared towards dissonant or disastrous physical events. Wagering on the past and future importance of abrupt climate change, the article explores a way of engaging with catastrophic climatic change that stresses the inherent volatility and unpredictability of earth process, and the no-less-inherent vulnerability of the human body. Drawing on Bataille and Derrida, it proposes a way of nestling the issue of environmental justice within a broader sense of immeasurable indebtedness to those humans who endured previous episodes of abrupt climate change, and considers the idea of experimentation and generosity without reserve.

Social theorists, drawing on the study of complex dynamical systems to address global processes, tend to evoke an immanent globality devoid of a constitutive otherness or outside. However, as well as dealing with the internal dynamics of systems, complexity studies point to the mutual implication of systems and their surroundings: a concern that resonates with the interest in the convolutions of the inside–outside relationship prominent in post-structural philosophies. This article, looking at theories about the dynamical characteristics of the solar system, (...) galaxy and universe, develops the idea of an ex-orbitant globality that treats the earth as a system in active and ongoing interchange with its cosmic environment. A sense of the inevitable excess and unpredictability that attends this openness to the cosmos and to further other-than-human influences, it is suggested, has repercussions for the way we respond to environmental change injecting an element of abyssal undecidability into all our deliberations.

Biosemiotics is the synthesis of biology and semiotics, and its main purpose is to show that semiosis is a fundamental component of life, i.e., that signs and meaning exist in all living systems. This idea started circulating in the 1960s and was proposed independently from enquires taking place at both ends of the Scala Naturae. At the molecular end it was expressed by Howard Pattee’s analysis of the genetic code, whereas at the human end it took the form of Thomas (...) Sebeok’s investigation into the biological roots of culture. Other proposals appeared in the years that followed and gave origin to different theoretical frameworks, or different schools, of biosemiotics. They are: (1) the physical biosemiotics of Howard Pattee and its extension in Darwinian biosemiotics by Howard Pattee and by Terrence Deacon, (2) the zoosemiotics proposed by Thomas Sebeok and its extension in sign biosemiotics developed by Thomas Sebeok and by Jesper Hoffmeyer, (3) the code biosemiotics of Marcello Barbieri and (4) the hermeneutic biosemiotics of Anton Markoš. The differences that exist between the schools are a consequence of their different models of semiosis, but that is only the tip of the iceberg. In reality they go much deeper and concern the very nature of the new discipline. Is biosemiotics only a new way of looking at the known facts of biology or does it predict new facts? Does biosemiotics consist of testable hypotheses? Does it add anything to the history of life and to our understanding of evolution? These are the major issues of the young discipline, and the purpose of the present paper is to illustrate them by describing the origin and the historical development of its main schools. (shrink)
