Explanation is a perennially hot topic in philosophy of science. Yet philosophers have exhibited a curious blind spot to the questions of how explanatory projects develop over time, as well as what processes are involved in generating their developmental trajectories. This paper examines these questions using research into the end-Permian mass extinction as a case study. It takes as its jumping-off point the observation that explanations of historical events tend to grow more complex over time, but it goes beyond this (...) observation by scrutinizing the processes responsible for generating this pattern. Surveying several decades of research into the end-Permian extinction, I suggest that the principal “driver” of explanation in geohistory is non-explanatory work: work that is undertaken to increase our descriptive understanding of a phenomenon, not to test a particular explanatory claim. Non-explanatory work drives explanation by imposing or eliminating demands on explanation, and by furnishing new resources for constructing explanatory models. Explanations grow more complex because the demands on explanation tend to increase with ongoing characterization of the target phenomenon, and characterization tends grows the roster of explanatory resources. However, the fact that non-explanatory work sometimes eliminates demands on explanation means that this trend is not irreversible. I suggest that to achieve a more rounded view of the dynamics of explanation, philosophers should ask how research into complex phenomena is organized, as well as how explanatory progress depends upon the coordination of different kinds of material and epistemic resources.

This paper examines the emergence of a new approach to stratigraphic complexity, first in geology and then, following its creative appropriation, in paleobiology. The approach was associated with a set of models that together transformed stratigraphic geology in the decades following 1970. These included the influential models of depositional sequences developed by Peter Vail and others at Exxon. Transposed into paleobiology, they gave researchers new resources for studying the incompleteness of the fossil record and for removing biases imposed by the (...) processes of sedimentary accumulation. In addition, they helped reconfigure the cultural landscape of paleobiology, consolidating a growing emphasis on fieldwork and eroding the barrier that had been erected in the 1970s between “paleontology” and “paleobiology.” This paper traces these developments, paying special attention to the simulation models of stratigraphic paleobiologist Steven Holland. It also considers how the integration of sequence and event stratigraphy and paleobiology has begun to influence long-running discussions of incompleteness and bias in the fossil record. (shrink)

This paper analyses the hegemony of the growth paradigm through the example of its naturalisation in capitalist production and consumption relations. Applying a combination of theoretical elements from the Marxian tradition, the Regulation approach and Bourdieusian sociology, emphasis is placed on how the growth imperative is reflected in people's minds and bodies. It becomes hegemonic because it appears to be the natural way of steering economy and society. As a result, all people – including working people – benefit from the (...) continuation of growth. To overcome the growth paradigm, activists would need to build on a crisis of the ‘objective’ structures of economy and society. (shrink)

Over the past century or more, cognitive neuropsychologists have discussed many of the issues raised in this volume. On the basis of this literature, we argue that autism is not a single homogeneous condition, and so can have no single cause. Instead, each of its symptoms has a cause, and the proper study of autism is the separate study of each of these symptoms and its cause. We also offer evidence to support the radical view advanced by Stoljar and Gold (...) in this volume, namely, that in explaining such syndromes the cognitive level of explanation has priority over the neuroscientific.

For this eighth edition he also wrote a new chapter on the quantum theory of solids.

The paper defends the view that events are the basic relata of causation, against arguments based on linguistic analysis to the effect that only facts can play that role. According to those arguments, causal contexts let the meaning of the expressions embedded in them shift: even expressions possessing the linguistic form that usually designates an event take a factual meaning.However, defending events as fundamental relata of causation turns out to be possible only by attributing a – different – causal role (...) to facts as well. The role of facts in causation is characterized as «causal responsibility». This relation, and its connection to causation between events, is clarified by way of the analysis of different inference patterns between causal statements of the two sorts: statements linking events and statements linking facts.

Pragmatism is a direct response to the notion that some branches of philosophy lead to dead ends or lack practical applications. The Protogen stealth ships provide an interesting example. In The Expanse, the protomolecule disassembles and reassembles human bodies in random and horrific ways. Eros had to be sacrificed to protect the rest of humanity from the threat of the protomolecule. The Eros incident illuminates the way the remorseless logic of utilitarianism can lead to dreadful results. The Expanse allows us (...) to look at different views on the moral limits of science. It also illuminates our shared humanity. The Expanse suggests that when we lose sight of our humanity, even if the goal is to save humanity, we make the wrong decisions. (shrink)

"... no comprehensive scholarly study of the conceptual development of quantum mechanics has heretofore appeared. The popular or semiscientific publications available hardly skim the surface of the subject... The publication... seems therefore to fill an important lacuna in the literature on the history and philosophy of physics." -- Pref.

The question at issue is to develop a computational interpretation of Girard's Linear Logic [Girard, 1987] and to obtain efficient decision algorithms for this logic, based on the bottom-up approach. It involves starting with the simplest natural fragment of linear logic and then expanding it step-by-step. We give a complete computational interpretation for the Horn fragment of Linear Logic and some natural generalizations of it enriched by the two additive connectives: and &. Within the framework of this interpretation, it becomes (...) possible to explicitly formalize and clarify the computational aspects of the fragments of Linear Logic in question and establish exactly the complexity level of these fragments. In particular, the simplest natural Horn fragment of Linear Logic is proved to be NP-complete. As a corollary, we obtain the affirmative solution for the problem ): whether the multiplicative fragment of linear logic is NP-complete. (shrink)
