The pandemic has been the most vivid agent of change that many of us have known. But it has not changed everything: plenty of the institutions, norms, and practices that sustain racial capitalism, settler colonialism, and cisheteropatriarchy have either weathered the storm of the crisis or been nourished by its effects. And yet enough has changed for us to see that the pandemic has profoundly recontextualised those structures and systems of violence, bringing us into a fresh negotiation with, for example, (...) the question of how we discuss and imagine freedom. Responding in part to this unexpected provocation, activist-scholars Robyn Maynard and Leanne Betasamosake Simpson forged a collaboration from the lockdown of 2020, corresponding by letter to create their forthcoming book, Rehearsals for Living, due to be published by Haymarket Books (US) and Knopf (Canada) in 2022. In this interview, we asked them to explain the epistolary form of the book and expand on the concept of “rehearsal”, before inviting them to reflect on a series of issues that animate our current crises: the politics of recognition; the notion of apocalypse; ways to disrupt linear temporalities; practises of reciprocity against proprietary logics; the gendered violence of state apparatuses; and worldbuilding as a method of resistance. In their expansive answers, Robyn and Leanne draw on their experiences as organisers and educators, commenting on anticolonial struggles, the Movement for Black Lives, and the rise of abolition discourse. Stressing the need to build a multiplicity of shared homespaces in the face of racial/colonial capitalism and organized abandonment, they challenge us to rethink the predicaments and possibilities of the present, enabling us to imagine futures liberated of extractivist, carceral governance – “planting more liberatory futures in the present”, as Robyn puts it. The task of sowing those seeds is a collective praxis of rewriting the narratives that constitute us, refusing to hear that nothing can change and insisting that everything must. (shrink)

The use of informational terms is widespread in molecular and developmental biology. The usage dates back to Weismann. In both protein synthesis and in later development, genes are symbols, in that there is no necessary connection between their form (sequence) and their effects. The sequence of a gene has been determined, by past natural selection, because of the effects it produces. In biology, the use of informational terms implies intentionality, in that both the form of the signal, and the response (...) to it, have evolved by selection. Where an engineer sees design, a biologist sees natural selection. (shrink)

A slew of recent political theorists—many taking their cue from the political writings of Bernard Williams—have recently contended that political normativity is its own kind of normativity, distinct from moral normativity. In this article, we first attempt to clarify what this claim amounts to and then reconstruct and interrogate five major arguments for it. We contend that all these arguments are unconvincing and fail to establish a sense in which political normativity is genuinely separate from morality.

This paper makes the case for a revision of contemporary forms of political realism in political theory. I argue that contemporary realists have gone awry in increasingly centring their approach around a metaethical claim: that political theory should be rooted in a political form of normativity that is distinct from moral normativity. Several critics of realism have argued that this claim is unconvincing. But I suggest that it is also a counterintuitive starting point for realism, and one unnecessary to avoid (...) the ‘applied morality’ approach to political theory that realists oppose. Instead, realism should be methodologically orientated around what I term ‘empirically constitutive political realities’ - enduring features of real political contexts that are systematically consequential in their normative implications. Realists can persuasively argue that such empirically constitutive political realities must be attended to in political theory-building, and not merely treated as a context in which independently formulated moral theories are simply applied. This framing of realism accords real politics a genuinely foundational theoretical role, but without requiring any contentious metaethical stance about a non-moral political normativity. I explain some methodological implications that follow for realism – in particular the need to prioritise empirically grounded theorisation of real political contexts over abstract and rather essentialist claims about ‘the political’. I also argue that such a framing of realism helps engender a more accurate, less divisive, and more pluralist conception of methodological debates within political theory. (shrink)

We introduce a new operator – belief fusion– which aggregates the beliefs of two agents, each informed by a subset of sources ranked by reliability. In the process we definepedigreed belief states, which enrich standard belief states with the source of each piece of information. We note that the fusion operator satisfies the invariants of idempotence, associativity, and commutativity. As a result, it can be iterated without difficulty. We also define belief diffusion; whereas fusion generally produces a belief state with (...) more information than is possessed by either of its two arguments, diffusion produces a state with less information. Fusion and diffusion are symmetric operators, and together define a distributive lattice. Finally, we show that AGM revision can be viewed as fusion between a novice and an expert. (shrink)

Inevitably, much of this reply will concern points on which I disagree with one or other of the commentators. I should start, therefore, by saying that I am delighted to find that their thinking is in many ways similar to my own, and that a serious attempt is under way to clarify the concept of information in biology.

Concentrating on problems that commonly perplex general readers and beginning students, John Maynard Smith discusses fundamental issues in biology, with emphasis on evolution, development, and cognition. He provides a nontechnical account of molecular genetics, which is the foundation of modern biology, and explores such issues as heredity, animal behavior, the definition and origin of life, the brain and how we know things, artificial and natural intelligence, and genetics. The book is unique in presenting modern ideas in terms that can (...) be understood without an in-depth knowledge of biology. (shrink)

Two important methodological debates in political theory concern (i) the place of historical research and interpretation in normative inquiry; and (ii) the importance of comparing different cultural traditions of political thought. The first question animates a long-standing controversy over the relative importance of ‘history of political thought’ versus ‘philosophy’ in political theory, while the second has been central to the recent growth of ‘comparative political theory’. Despite both debates being concerned, in fundamental ways, with history and comparison, they have remained (...) surprisingly disconnected from broader debates in the humanities and social sciences about the use of comparative history and, in particular, of the prominent methodological approach in political science known as ‘comparative historical analysis’. This may reflect the fact that the debates over history of political thought and comparative political theory have fundamentally revolved around thought—history as the history of thought and comparison as the comparison of thought—whereas comparative historical analysis is more centrally focused on the study of political behaviour. In this paper I suggest that this neglect of comparative historical analysis in political theory represents a missed opportunity. Like other forms of social scientific inquiry, comparative historical analysis can yield important empirical knowledge for political theorists. But I wish to more ambitiously suggest that comparative historical analysis can also be adapted for conducting normative political theory itself. I summarise the key features of comparative historical analysis for political theorists, and explain how its use of historical cases can supplement both the use of imaginary thought experiments and the study of contemporary politics. I then delineate three specific ways in which comparative historical analysis might be used to support normative inquiry: deductive testing, inductive construction, and casuistic elaboration. All three, I argue, can help meet recent calls to bring the study of real political behaviour more centrally into political theory research. (shrink)

In Southeast Asian countries (SEA), road transport accounts for the main energy consumption and CO2 emission. Air pollution is a major concern in densely populated cities such as Bangkok, Manila, and Kuala Lumpur. The main objective of this paper is to give insights on trends of transport development, car ownership, and CO2 emissions in Southeast Asia. This study also attempts to review the successful transportation policies around the globe and to introduce the possible instruments that can help reduce air pollution (...) in Southeast Asian countries. Economic instruments to estimate the benefits of a cleaner environment due to new policies are introduced as well. The results of this research could help policy makers consider approaches that could internalize external costs of transportation and maximize the societal welfare. (shrink)

Financial sustainability of protected areas is one of the main challenges of management. Financial self-sufficiency is an important element in improving conservation effort in these areas. This study seeks to review best practices in recreational fee systems in different countries and to find a relevant entry fee for a wildlife sanctuary in Malaysia. The revenue of the National Elephant Conservation Center (NECC) in Kuala Gandah, Malaysia, comes from several sources, including the national government, but all these budgetary sources are strained (...) by tighter public budgets and greater demands. The present study investigates the introduction of visitor entrance fees to supplement an otherwise inadequate budget for supporting the operational costs of the sanctuary. Factor analysis and a double-bounded contingent valuation method were combined to estimate tourists' willingness to pay (WTP) the proposed entrance fee. Factor analysis showed that respondents' motivation to support the NECC with user fees is conditioned by their direct experiences with elephants, their satisfaction with NECC's educational programs and services, and other experiences it gives to users. The WTP model considered respondents' four motivation factors with their sociodemographic characteristics. Since NECC visitors arrive from both within and outside the country, this study suggests to center managers a two-tier fee structure (residents vs. nonresidents of Malaysia), based upon mean WTP estimates. This study further suggests that revenue from such an entrance fee for NECC could support the Center's management and development costs. © 2015 Elsevier B. (shrink)

Extensive revision of 1998 entry (for expanded new edition of Encyclopedia of Aesthetics) to include, besides mini-essays on technology, art, depiction and the aesthetic, a development of the last in terms of facture--the materials of a work and their working there, as perceivable in the work.

Richard Levins (1930-2016) was an outstanding ecologist, population geneticist, biomathematician, philosopher of science, complexity theorist, and Marxist. Key to all aspects of his work was a dialectical logic of process and change. His work provides a framework for the understanding of crises in environment and society and their analytic relationship with capitalism and imperialism, as well as the tools for the critique of biological determinist justifications for the existing structures of power. This anthology pays tribute to Levins by carrying forward (...) his work in the development of the understanding of the dialectics of nature and society. -/- The contributions are organized into four sections--Dialectics in Wholistic Research; Political Ecology and Health; Complex Systems; and Reminiscences and Tributes. The authors are as almost as hard to label as Levins; the fields they draw from range from biomathematics to NGO activism; environmental policy to island and aquatic ecology; eco-justice podcasting to biogeochemistry; reflective practice to science-in-society, agroecology to public health.

'Doing an Aristotle' on Form: a highly compressed attempt to explain what we mean by the ambiguous term "form" in visual arts.

From a perceptual psychology and philosophy conference on linear perspective: points out standard fallacies about perspective, then challenges psychology's and philosophy's widespread assumption that a satisfactory understanding of depiction in any medium can be reached via theories of spatial--or any other kind of--visual perception.

Concerns photography and time as duration, sequence, equability, past and present (illus.).

This paper addresses standard questions regarding comics and the arts (comics and fine arts, image and word combinations), then poses and addresses the neglected, but deeper and wider--thus philosophical--question, of how depictions, not just words, can have mental contents at all, including light, funny, scathing, comic ones.

First ever philosophy treatise on photography, analytic in approach but sensitive to photo-history, not confined to aesthetics or art (illus.), Walker Evans photo on cover. Papercover printing, Dec. 2000.

Recovery and original English translation, with commentary and notes on metaphysical references, of parodic 1902 letter by Miguel de Unamumo, supporting the view that he was a crucial figure in the transformation of isolated, traditional, cultural practices of paperfolding into the modern, international, autonomous, minor artform postwar termed 'origami'.
