2014 (Accepted for Publication; Forthcoming). "The Structure of Scientific Theories" for Stanford Encyclopedia of Philosophy. [Check SEP "Projected Table of Contents" here. Email me for a copy.]
- Scientific inquiry has led to immense explanatory and technological successes, partly as a result of the pervasiveness of scientific theories. Relativity theory, evolutionary theory, and plate tectonics were, and continue to be, wildly successful families of theories within physics, biology, and geology. Other powerful theory clusters inhabit comparatively recent disciplines such as cognitive science, climate science, molecular biology, microeconomics, and Geographic Information Science (GIS). Effective scientific theories magnify understanding, help supply legitimate explanations, and assist in formulating predictions. Moving from their knowledge-producing representational functions to their interventional roles (Hacking 1983), theories are integral to building technologies used within consumer, industrial, and scientific milieus.
- This encyclopedia entry introduces philosophical debates about the structure of scientific theories, focusing on a comparison of the three major views: Syntactic, Semantic, and Pragmatic. The Syntactic View construes the structure of a theory as its rational reconstruction in a logical language; the Semantic View holds that a theory is a collection of nonlinguistic mathematical models; and the Pragmatic View claims that a theory is a heterogeneous collection of sentences, models, exemplars, practices, and other features.
- Each of these views answers questions such as the following in unique ways. What is the best characterization of the composition and function of scientific theory? How is theory linked with world? Which philosophical tools can and should be employed in describing and reconstructing scientific theory? Is an understanding of practice and application necessary for a comprehension of the core structure of a scientific theory? How are these three views ultimately related? After historically contextualizing and critically assessing each of these views, the essay concludes by suggesting a pluralistic “complementarity strategy” that grants a legitimate place to each of them.

- Which methods are available for studying such complex and multi-factorial phenomena as sexuality, intelligence, and autism, and is there any way of aggregating multiple perspectives so as to arrive at a “total explanation”? This article explores thinking about causation in the temporal evolution of biological and behavioral systems, with special attention paid to statistical methods and the role of determinism. In the end, it is suggested that apparently incommensurable projects and methodologies might in fact produce a “floodlight” vision of reality constituted by various particular “spotlights.”
2014. With Carlos Montemayor. Review of Stanislas Dehaene and Elizabeth Brannon Space, Time and Number in the Brain. Searching for the Foundations of Mathematical Thought. (Academic Press; Elsevier), The Mathematical Intelligencer. [Download PDF from philpapers.com.]
- This co-written piece reviews Dehaene and Brannon’s book about the neurological and psychological foundations of mathematical cognition. This anthology searches for the foundations of mathematical thought through an impressive collection of twenty-one articles divided into five sections: (1) Mental Magnitudes and Their Transformations, (2) Neural Codes for Space, Time and Number, (3) Shared Mechanisms for Space, Time and Number?, (4) Origins of Proto-Mathematical Intuitions, (5) Representational Change and Education. While this book represents an important contribution by leading scholars, there remain a number of unsolved problems pertaining to the interpretation of empirical data, the cognitive-epistemic foundations of mathematics, and linguistic representation.
2014. "Mapping Kinds in GIS and Cartography," in Natural Kinds After the Practice-Turn (Catherine Kendig ed.), Pickering & Chatto, London. [Download PDF from philpapers.com; click here for a description of the anthology.]
- This book chapter explores the use of natural kinds in the data modeling and map generalization practices of GIS and cartography. Collecting and collating geographical data, building geographical databases, and engaging in spatial analysis, visualization, and map-making all require organizing, typologizing, and classifying geographic space, objects, relations, and processes. These practices of making and using kinds are contextual, fallible, plural, and purposive. The mapping of kinds is just one aspect of a possible philosophy of GIS and cartography (PGISC), which may provide a novel method for addressing concerns of realism, representation, explanation, reduction, and theory structure in philosophy of science more generally.
- This article examines both the danger and usefulness of abstraction in science and philosophy through an examination of the writings of William James and John Dewey. According to these two pragmatists, whenever one forgets (1) the particular function, (2) historical conditions of emergence, and/or (3) appropriate analytical level of an abstraction, the products and processes of abstraction become inappropriately universalized, narrowed, and/or ontologized. This article elucidates the abstraction-reification account diagnosed by James and Dewey and locates it in contemporary scientific work, dubbing the problem at hand “pernicious reification.”
2014. The Genetic Reification of "Race"? A Story of Two Mathematical Methods. Critical Philosophy of Race 2 (2): 204-223. [Download PDF from philpapers.com.]
- Two families of mathematical methods lie at the heart of investigating the hierarchical structure of genetic variation in Homo sapiens: diversity partitioning, which assesses genetic variation within and among predetermined groups, and clustering analysis, which simultaneously produces clusters and assigns individuals to these “unsupervised” cluster classifications. While mathematically consistent, these two methodologies seem to ground diametrically opposed claims about the reality of human races. Moreover, modeling results are subject to being perniciously reified – conflated and confused with the world – because they are sensitive to preexisting theoretical commitments to certain linguistic, anthropological, and geographic human groups. This fact belies standard realist and antirealist interpretations of “race,” and supports a pluralist conventionalist interpretation.
- This co-authored article distinguishes three concepts of “race”: bio-genomic cluster/race, biological race, and social race. It maps out realism, antirealism, and conventionalism about each of these concepts, across three important historical episodes. Upon inspection, each episode also reveals a variety of commitments to the metaphysics of race. The article concludes by interrogating the relevance of these scientific discussions for political positions and a post-racial future.
2013. With Fabrizzio Guerrero McManus. Review of Michael Ruse The Philosophy of Human Evolution. (Cambridge University Press), Evolution. [Download PDF from philpapers.com.]
- This is a co-written review of a book that covers several topics relevant to human evolution: evolutionary theory, the concept of progress, knowledge, morality, sex and race, and evolutionary medicine. Although Ruse’s book is clearly and effectively written and foregrounds a diversity of important questions regarding human evolution, it would benefit our understanding of both human evolution and the role of the historian and philosopher of science to consider further theoretical frames from evolutionary biology that go beyond his Dawkins-style view of evolution. Such frames include multilevel and hierarchical selection theories, epigenetics, feminist science, and developmental systems and niche construction theory. One role of the philosopher and historian of science is to identify, negotiate, and potentially integrate multiple theoretical perspectives.
2013. Review of Stephen Stich Collected Papers. Vol 2. Knowledge, Rationality, and Morality (Oxford University Press), Notre Dame Philosophical Reviews. [Read review on NDPR's website.]
- This is a review of a volume of papers by Stephen Stitch, a philosopher who has consistently argued that our conceptions of knowledge and morality must be responsive to cognitive science and cultural context. Stitch puts real concrete individuals back into analytic philosophy, as a welcome corrective to overly idealized notions of reasoning and reasoning agents. After exploring Stitch’s themes of (1) cognitive diversity, (2) biases and heuristics, (3) psychological foundations of morality, and (4) philosophical methodology, the review concludes by recommending this volume to a broad audience of analytic philosophers, psychologists, and cognitive scientists.
- This is a co-written article arguing that genomic data and models will not settle questions about the reality of race. First, different sub-disciplines of biology interested in population structure employ distinct concepts, aims, and measures and models, thereby producing cross-cutting categorizations of population subdivisions rather than a single, universal biogenomic concept of ‘race.’ Second, within each sub-discipline, genomic results are consistent with, and map multiply to, racial realism and anti-realism. We thus defend a constructivist conventionalism about biogenomic racial ontology. Political agendas, social programmes, and moral questions premised on the existence of naturalistic race should accept that no scientifically grounded racial ontology is forthcoming, and adjust presumptions, practices and projects accordingly.
- This is a co-written article examining two controversies regarding the appropriate characterization of hierarchical and adaptive evolution in natural populations. First, there is the controversy over the relative roles of random genetic drift, natural selection, population structure, and interdemic selection in adaptive evolution begun by Sewall Wright and Ronald Aylmer Fisher. Second, there is the Units of Selection debate, spanning both the biological and the philosophical literature and including the impassioned group-selection debate. We postulate that the reason for the lack of interaction between these debates can be found in the differing focus of each controversy, which is itself determined by distinct general styles of scientific research guiding each discourse: a focus on adaptive process in the Wright-Fisher debate, instructed by the mathematical modeling style; and a focus on adaptive product in the Units of Selection controversy, guided by the function style.
