Explanation and categorization: How “why?” informs “what?”

Recent theoretical and empirical work suggests that explanation and categorization are intimately related. This paper explores the hypothesis that explanations can help structure conceptual representations, and thereby influence the relative importance of features in categorization decisions. In particular, features may be differentially important depending on the role they play in explaining other features or aspects of category membership. Two experiments manipulate whether a feature is explained mechanistically, by appeal to proximate causes, or functionally, by appeal to a function or goal. Explanation type has a significant impact on the relative importance of features in subsequent categorization judgments, with functional explanations reversing previously documented effects of ‘causal status’. The findings suggest that a feature’s explanatory importance can impact categorization, and that explanatory relationships, in addition to causal relationships, are critical to understanding conceptual representation.     

Underdetermination and Rational Choice of Theories

The underdetermination of theory by data argument (UD) is traditionally construed as an argument that tells us that we ought to favour an anti-realist position over a realist position. I argue that when UD is constructed as an argument saying that theory choice is to proceed between theories that are empirically equivalent and adequate to the phenomena up until now, the argument will not favour constructive empiricism over realism. A constructive empiricist cannot account for why scientists are reasonable in expecting one theory to be empirically adequate rather than another, given the criteria he suggests for theory choice.

EXPLANATION, SOCIAL SCIENCE, AND THE STUDY OF RELIGION: A RESPONSE TO SEGAL WITH COMMENT ON THE ZYGON EXCHANGE

Abstract. In the issue of Zygon devoted to methodological reflection on the boundaries between natural science, social science, and theology (September 1990), Edward 0. Wilson pointed to the hierarchical tension between disciplines and antidisciplines. Working within this framework, Robert Segal outlined several “misconceptions of social science” held by religionists who fear it reduces, or “explains away” their subject. Philip Gorski, Nancey Murphy, and Kenneth Vaux suggested greater harmony but left Segal's challenge largely unaddressed. Religionists, says Segal, distrust social science because they think it ignores “the believer's point of view,” denies the “irreducibility” of religion, prefers materialist and mechanical explanations, and denies religious truth. Do religionists really claim all, or just some of these things? Are some perhaps not misconceptions, but accurate understandings of a real conflict? This article contends that distinctions need to be made; that at most, the humanistic assumptions of religionists compete with only one form of social science–reductionism; and further, that where conflict does arise, it is scientifically beneficial. Religionists differ from theologians, who argue from confessional premises, but the two are allied in opposing reductionism. Precisely because it is genuine, the debate with reductionist social science promises to advance understanding.     

Does “Intelligent Design” Have a Chance? An Essay Review

A number of authors have agued the case that there is empirical evidence that the universe (or particular configurations within it) must be the outcome of intelligent design. Recent books by William Dembski and Dean Overman, though different in style and level of argumentation, reach a similar conclusion: the universe, or certain forms within it, cannot be explained without appeal to design as a mode of causation. But exactly what is the operative definition for intelligent design in these works? And how convincing is their case for the necessity of appealing to this type of design in causal explanations?     

Über zwei Formen von Realismus in der Quantentheorie

On Two Types of Realism in Quantum Theory. Current realist approaches to the foundations of quantum theory emphasize the dichotomy between (Copenhagen) positivism and ‘beable’-realism. Recently it was even attempted to turn this picture into two (equally possible) histories in order to legitimate Bohmian Mechanics as a viable alternative. This paper argues that this dichotomy is philosophically inadequate and historically questionable by embedding it into the philosophical discussion on positivism and realism that has taken place since the 1920s. Logical Empiricists back then advocated empirical realism and contrasted it to absolutistic metaphysical realism. From this viewpoint David Bohm's ‘beable’-realism combines elements of Mach's sensualism with a pre-Kantian metaphysics. As Wesley Salmon's position shows, empirical realism can become quite pronounced without relapsing into Bohmian philosophy. Instead it arrives close to the GRWP-interpretation. Hence, when Bernard d'Espagnat binds both together as ‘ontological interpretations’, he blurs the borderline between empirical and metaphysical realism that his Veiled Reality has set out to draw, quite in concordance with Logical Empiricism.

On radical conceptual revolutions in social science

The paper considers arguments for and against correction and elimination of the basic conceptual categories as well as theories of social science. It is argued that some correction of at least some basic social notions is called for. A great part of the paper consists in a conceptual investigation of such notion of correction in terms of different notions of corrective explanation.     

Real World Justice

Despite a high and growing global average income, billions of human beings are still condemned to lifelong severe poverty with all its attendant evils of low life expectancy, social exclusion, ill health, illiteracy, dependency, and effective enslavement. We citizens of the rich countries are conditioned to think of this problem as an occasion for assistance. Thanks in part to the rationalizations dispensed by our economists, most of us do not realize how deeply we are implicated, through the new global economic order our states have imposed, in this ongoing catastrophe. My sketch of how we are so implicated follows the argument of my book, World Poverty and Human Rights, but takes the form of a response to the books critics.     

Why-questions, determinism and circular reasoning

In this article I shall aim at showing that there exists beneath the surface of many why-questions about human behaviour a nest of deterministic assumptions which can preclude their ever being truly answered. A symptom of the presence of these underlying assumptions can be observed in an explanation-seeking dialogue in which the questioner persistently tries to discover why a certain human behaviour occurred. He repeats his why-question until he gets the type of answer he wants, but in the process he effectively reasons in a circle. If the repeated questioning with its implied circular reasoning becomes chronic, then the questioner will beg the question with regards to the answer he desires and consequently run the risk of missing the truth.     

Using Social Representations Theory to Examine Lay Explanation of Contemporary Social Crises: The Case of Ireland's Recession

Social actors operate under a basic imperative to construct explanations for the events that surround them. Many issues that dominate the societal agenda today are not available to direct perception, derive from traditionally expert domains and are relatively remote from immediate local experience. This presents a challenge for lay explanation of these issues. Social representations theory offers a useful framework through which the construction of lay explanation for such issues can be examined. The current study recruited this theoretical framework to investigate lay explanations of the recent economic recession in Ireland. Data consisted of semi‐structured interviews with 14 members of the public and a web‐based survey (N = 138). The data suggested that explanations for the recession could be organised into three major themes: Power, Ordinary People and Fatalism. Strictly economic explanations were eschewed; instead, people drew upon a wide range of ideas about society, politics, morality, public spheres and personhood. The implications of these findings for understanding lay explanation of contemporary social crises are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Intentional concepts in cognitive neuroscience

In this article, I develop an account of the use of intentional predicates in cognitive neuroscience explanations. As pointed out by Maxwell Bennett and Peter Hacker, intentional language abounds in neuroscience theories. According to Bennett and Hacker, the subpersonal use of intentional predicates results in conceptual confusion. I argue against this overly strong conclusion by evaluating the contested language use in light of its explanatory function. By employing conceptual resources from the contemporary philosophy of science, I show that although the use of intentional predicates in mechanistic explanations sometimes leads to explanatorily inert claims, intentional predicates can also successfully feature in mechanistic explanations as tools for the functional analysis of the explanandum phenomenon. Despite the similarities between my account and Daniel Dennett's intentional-stance approach, I argue that intentional stance should not be understood as a theory of subpersonal causal explanation, and therefore cannot be used to assess the explanatory role of intentional predicates in neuroscience. Finally, I outline a general strategy for answering the question of what kind of language can be employed in mechanistic explanations.
