Phylogenetic trees are meant to represent the genealogical history of life and apparently derive their justification from the existence of the tree of life and the fact that evolutionary processes are treelike. However, there are a number of problems for these assumptions. Here it is argued that once we understand the important role that phylogenetic trees play as models that contain idealizations, we can accept these criticisms and deny the reality of the tree while justifying the continued use of trees (...) in phylogenetic theory and preserving nearly all of what defenders of trees have called the “importance of tree thinking.”.

Determinism has long been a core assumption in many forms of behaviorism, including radical behaviorism. However, this assumption has been a stumbling block for many—both within and outside the field of radical behaviorism—resulting in misunderstanding and misrepresentation. The following paper provides a descriptive taxonomy of four kinds of determinism assumed or asserted in the radical behavioral literature. This taxonomy is intended to organize these deterministic positions, provide working definitions, and explore their implications. Through this work, it is hoped that behaviorists (...) and nonbehaviorists alike will possess a clearer understanding of determinism in behavioral analysis. (shrink)

This volume presents mathematical game theory as an interface between logic and philosophy.

A general account of modeling in physics is proposed. Modeling is shown to involve three components: denotation, demonstration, and interpretation. Elements of the physical world are denoted by elements of the model; the model possesses an internal dynamic that allows us to demonstrate theoretical conclusions; these in turn need to be interpreted if we are to make predictions. The DDI account can be readily extended in ways that correspond to different aspects of scientific practice.

Maps and mapping raise questions about models and modeling and in science. This chapter archives map discourse in the founding generation of philosophers of science (e.g., Rudolf Carnap, Nelson Goodman, Thomas Kuhn, and Stephen Toulmin) and in the subsequent generation (e.g., Philip Kitcher, Helen Longino, and Bas van Fraassen). In focusing on these two original framing generations of philosophy of science, I intend to remove us from the heat of contemporary discussions of abstraction, representation, and practice of science and thereby (...) see in a more distant and neutral light the many productive ways in which maps can stand in analytically for scientific theories and models. The chapter concludes by complementing the map analogy – i.e., a scientific theory is a map of the world – with a model analogy, viz., a scientific model is a vehicle for understanding. (shrink)

The purpose of this work is to address what notion of geometrical object and geometrical figure we have in different kinds of geometry: practical, pure, and applied. Also, we address the relation between geometrical objects and figures when this is possible, which is the case of pure and applied geometry. In practical geometry it turns out that there is no conception of geometrical object.

In this paper, I discuss the problem of scientific laws in general and laws of biology in particular. After reviewing the debate around the existence of laws in biology, I examine the subject in the light of the structuralist notion of a fundamental law and argue for the law of matching as the fundamental law of genetics.

. The question of whether or not our universe is deterministic remains of interest to both scientists and theologians. In this essay I argue that this question can be solved only by metaphysical decision and that no scientific evidence for either determinism or indeterminism will ever be conclusive. No finite being, no matter how powerful its cognitive abilities, will ever be able to establish the deterministic nature of the universe. The only being that would be capable of doing so would (...) be one that is at once transcendent and immanent. Such a being is compatible with the God of the Christian tradition, which yields that a deterministic worldview is compatible with a deterministic worldview. A more important point is that because science is never able to establish the determinism of our universe, it can never definitely rule out divine action except on metaphysical grounds. (shrink)

Neo-positivism is dead. Let that imperfect designation stand for the project that dominated and defined the philosophy of science, especially in its Anglophone form, during the fifty or so years following the end of the Second World War. While its critics were many,1 its death was slow, and some think still to find a pulse.2 But die it did in the cul-de-sac into which it was led by its own faulty compass.

The article undertakes the problem of a Wittgensteinian background of Toulmin’s model of argument. While appreciating the original character of the investigations set out by Toulmin in The Uses of Argument, Wittgenstein’s ideas taken to be forerunners of both Toulmin’s philosophical method and the particular elements of the model of substantial argument are traced backward, to Toulmin’s earlier books: The Philosophy of Science (Toulmin, The philosophy of science. An introduction, Hutchinson University Library, London, 1953) and An Examination of the Place (...) of Reason in Ethics (Toulmin, An examination of the place of reason in ethics, Cambridge University Press, Cambridge, 1950). The technique of pinpointing the constituents of that model in the books preceding The Uses of Argument is superposing the layout of Toulmin’s model on the crucial arguments concerning the earlier books: the scientific one based on Newtonian optics and the moral one concerning keeping promises. Such a procedure allows identifying backing for warrants and argument fields with the methods of representation in The Philosophy of Science and with modes of reasoning in An Examination of the Place of Reason in Ethics. The former is traced to passages 6.3 ff of Wittgenstein’s Tractatus, while the latter—to the concept of word-games (the later Wittgenstein’s language games). The claim regarding Wittgenstein’s background is that in Toulmin’s view of Wittgenstein, some parts of Tractatus concerning representing are in line with Wittgenstein’s later reflections on language games; as well as that the overall method of The Uses of Argument goes along with Wittgenstein’s therapeutic approach to philosophical problems that have to be placed in the context of their ordinary use.

In 2003 I published a survey of Wittgenstein’s lectures in Public and Private Occasions. Much has been learned about his lectures since then. This paper revisits the earlier survey and provides additional material and corrections, which amount to over 25%. In case it is useful, I have provided interlinear pagination from the original publication.

Infinite regress arguments are part of a philosopher's tool kit of argumentation. But how sharp or strong is this tool? How effectively is it used? The typical presentation of infinite regress arguments throughout history is so succinct and has so many gaps that it is often unclear how an infinite regress is derived, and why an infinite regress is logically problematic, and as a result, it is often difficult to evaluate infinite regress arguments. These consequences of our customary way of (...) using this tool indicate that there is a need for a theory to re-orient our practice. My general approach to contribute to such a theory, consists of collecting and evaluating as many infinite regress arguments as possible, comparing and contrasting many of the formal and non-formal properties, looking for recurring patterns, and identifying the properties that appeared essential to those patterns. Two very general questions guided this work: How are infinite regresses generated in infinite regress arguments? How do infinite regresses logically function as premises in an argument? In answering these questions I clarify the notion of an infinite regress; identify different logical forms of infinite regresses; describe different kinds of infinite regress arguments; distinguish the rhetoric from the logic in infinite regress arguments; and suggest ways of improving our discussion and our practice of constructing and evaluating these arguments.

The Tree of Life has traditionally been understood to represent the history of species lineages. However, recently researchers have suggested that it might be better interpreted as representing the history of cellular lineages, sometimes called the Tree of Cells. This paper examines and evaluates reasons offered against this cellular interpretation of the Tree of Life. It argues that some such reasons are bad reasons, based either on a false attribution of essentialism, on a misunderstanding of the problem of lineage identity, (...) or on a limited view of scientific representation. I suggest that debate about the Tree of Cells and other successors to the traditional Tree of Life should be formulated in terms of the purposes these representations may serve. In pursuing this strategy, we see that the Tree of Cells cannot serve one purpose suggested for it: as an explanation for the hierarchical nature of taxonomy. We then explore whether, instead, the tree may play an important role in the dynamic modeling of evolution. As highly-integrated complex systems, cells may influence which lineage components can successfully transfer into them and how they change once integrated. Only if they do in fact have a substantial role to play in this process might the Tree of Cells have some claim to be the Tree of Life. (shrink)

“Scientific theories are maps of the natural world.” This metaphor is often used as part of a deflationary argument for a weak but relatively global version of scientific realism, a version that recognizes the place of conventions, goals, and contingencies in scientific representations, while maintaining that they are typically true in a clear and literal sense. By examining, in a naturalistic way, some relationships between maps and what they map, we question the scope and value of realist construals of maps—and (...) by extension of scientific representations. Deflationary philosophy of science requires more variegated stances. (shrink)

Este ensayo busca mostrar que la ciencia macroeconómica desde hace mucho tiempo no es una disciplina cuyas investigaciones están encuadradas dentro del denominado empirismo lógico y tampoco sus controversias se dirimen dentro del algúnparadigma al estilo de Thomas Kuhn, sino que está conformada por un conjunto de propuestas teóricas que conforman lo que Laudan denomina como “tradiciones de investigación”. Aunque los fenómenos que estudia la macroeconomía son externos a la consciencia del investigador, del diseñador de política económica y del público (...) en general, sus realizaciones tienden más hacia las propuestas de un realismo perspectivistade corte naturalista y que sus hallazgos expresan verdades acerca de las “tendencias” y “capacidades” que subyacen en los fenómenos económicos.This essay tries to show that macroeconomic science from a long time rather to make economic research taking account neo positivist principles and point of view is a discipline with different perspectives and theories within “research traditions” as Larry Laudan said. Although, whether the macroeconomic phenomena is outside of researchers, public policy makers, and people in general, the understanding of macroeconomic as a science trends to be a form of perspective realism with a methodological commitment to naturalism, using models as primary representational entities of economic problems, and where truth are about its trends and capacities as suggested Ronald GiereandNancy Cartwright.

Scientific development influences philosophical thought, and vice versa. If philosophy is to be of any use to the production, evaluation or application of biochemical knowledge, biochemistry will have to explicate its needs. This paper concentrates on the need for a philosophical analysis of methodological challenges in biochemistry, above all the problematic relation between in vitro experiments and the desire for in vivo knowledge. This problem receives much attention within biochemistry, but the focus is on practical detail. It is discussed how (...) a theoretical analysis can go beyond a naïve understanding of scientific success and failure in such cases. Several examples are presented to elucidate this issue, including the methodological implications of the precautionary principle, the possible interplay between theoretical methodology of biochemistry and the science studies, and the methodological complexities related to experimental protocol standardisation and use of instruments and kits.

In this paper, we will make explicit the relationship that exists between geometric objects and geometric figures in planar Euclidean geometry. That will enable us to determine basic features regarding the role of geometric figures and diagrams when used in the context of pure and applied planar Euclidean geometry, arising due to this relationship. By taking into account pure geometry, as developed in Euclid’s Elements, and practical geometry, we will establish a relation between geometric objects and figures. Geometric objects are (...) defined in terms of idealizations of the corresponding figures of practical geometry. We name the relationship between them as a relation of idealization. This relation, existing between objects and figures, is what enables figures to have a role in pure and applied geometry. That is, we can use a figure or diagram as a representation of geometric objects or composite geometric objects because the relation of idealization corresponds to a resemblance-like relationship between objects and figures. Moving beyond pure geometry, we will defend that there are two other ‘layers’ of representation at play in applied geometry. To show that, we will consider Euclid’s Optics. (shrink)

Toulmin is famously seen as the progenitor of informal logic and the related theory of argument and is first among many who seek to move the study of argument away from its roots in formal, especially mathematical, logic. Toulmin’s efforts, however, have been substantively criticized by Harvey Siegel, among others, for failing to offer the sort of foundation that, according to Siegel, even Toulmin sees to be required lest the theory of inquiry fall to impotent relativism. What I will attempt (...) to indicate in this paper is, that although Toulmin is correct in rejecting mathematical logic as standardly construed as an adequate theory of argument, and logical empiricist constructions as an adequate basis for the philosophical understanding of science, there is a significant role for metamathematics in the new logic. In particular, I will show how a formal model based on mature physical science rather than arithmetic furnishes crucial support to Toulmin, furnishing philosophical metaphors that afford the foundational support required for normativity and the clarification of key logical concepts required for a robust normative theory of argument in the context of inquiry.

The author argues that Michael Polanyi’s philosophy of science can be understood as an (unconscious) attempt to recapture elements of experience largely forgotten or repressed in modernity. Specifically, the author argues that Polanyi’s epistemology appears to draw on elements of oral—aural experience that have been relatively ignored by the heavily visual sensory orientation typical of modern Western societies. The author does this by first deriving the primary features of the modern objectivist conception of knowledge from Polanyi’s critique of objectivism and (...) then using the anthropological literature on the differences between oral and literate cultures to demonstrate that these same aspects of the objectivist paradigm correspond closely to typical features of literate, visual consciousness while Polanyi’s alternative formulations correspond to a more oral—aural orientation.

How distinct is European philosophy of science? The first step is to characterize what is or might be considered as ‘European philosophy of science’. The second is to analyse philosophy of the social sciences as a relevant case in the European contribution to philosophy of science. ‘European perspective’ requires some clarification, which can be done from two main angles: the historical approach and the thematic view. Thus, there are several structural and dynamic things to be considered in European philosophy of (...) science and compare with other conceptions: the topics discussed; the contents proposed; and the style of thought used. The case of philosophy of the social sciences is relevant for the historical approach and for the thematic view. Historically, the Erklären–Verstehen methodological controversy arose in this continent, where the main authors and most of the influential approaches are located. Thematically, we can consider the contributions made by these European approaches... (shrink)

I discuss eight theses espoused or occasioned by Toulmin: The validity standard is nearly always the wrong standard for real-life reasoning. Little in good reasoning is topic neutral. The probability calculus distorts much probabilistic reasoning. Scant resources have a benign influence on human reasoning. Theoretical progress and conceptual change are connected. Logic should investigate the cognitive aspects of reasoning and arguing. Ideal models are unsuitable for normativity. The role of the Can Do Principle.

Uskali Mäki has offered an innovative scientific realist account of Milton Friedman’s 1953 essay, ‘The Methodology of Positive Economics’, which directly challenges the dominant instrumentalist interpretation. This paper offers critical reflections on Mäki’s approach and interpretation. It is argued that Mäki’s method of rereading-rewriting the text is problematic; that an unforced instrumentalist account of unrealistic assumptions can be extracted from the text itself; and that seemingly realist passages can be plausibly read as expressing an instrumentalist stance.

The problem of the peculiarcharacter of chemical laws and theories is a central topic in philosophy of chemistry. Oneof the most characteristic and, at the sametime, most puzzling examples in discussions onchemical laws and theories is Mendeleev''speriodic law. This law seems to be essentiallydifferent in its nature from the exact laws ofclassical physics, the latter being usuallyregarded as a paradigm of science byphilosophers. In this paper the main argumentsconcerning the peculiar character of chemicallaws and theories are examined. The laws ofchemistry (...) are natural laws to the same extentas are the laws of physics. The law discoveredby Mendeleev is a normal law of nature. It isnot a law of physics, nevertheless, it is exactin the same philosophical sense as are the lawsof physics. The periodic system of chemicalelements was established by constructing anidealized system of idealized elements. Thefundamental idealization substantiated byexperimental chemistry was the chemicalelement as a place in the periodicsystem. (shrink)

As a contribution to current debates on the ‘social life of methods’, in this article we present an ethnomethodological study of the role of understanding within statistical practice. After reviewing the empirical turn in the methods literature and the challenges to the qualitative-quantitative divide it has given rise to, we argue such case studies are relevant because they enable us to see different ways in which ‘methods’, here quantitative methods, come to have a social life – by embodying and exhibiting (...) understanding they ‘make the social structures of everyday activities observable’ ( Garfinkel, 1967 : 75), thereby putting society on display. Exhibited understandings rest on distinctive lines of practical social and cultural inquiry – ethnographic ‘forays’ into the worlds of the producers and users of statistics – which are central to good statistical work but are not themselves quantitative. In highlighting these non-statistical forms of social and cultural inquiry at work in statistical practice, our case study is an addition to understandings of statistics and usefully points to ways in which studies of the social life of methods might be further developed from here.

1. It is natural to wonder what our multitude of successful physical theories tell us about the world—singly, and as a body. What are we to think when one theory tells us about a flat Newtonian spacetime, the next about a curved Lorentzian geometry, and we have hints of others, portraying discrete or higher-dimensional structures which look something like more familiar spacetimes in appropriate limits?

Toulmin (2001) sostiene que la invención de las disciplinas,un cambio iniciado en el siglo XVII, involucró factores tantointelectuales como institucionales. Intelectualmente, el uso dela geometría cartesiana como modelo de conocimiento proveyólos fundamentos; institucionalmente, la división del trabajo enprofesiones y disciplinas hizo el resto. Sin embargo, este cambiose produjo lentamente y sólo alcanzó su apogeo durante el sigloXX, con la conformación de lo que Snow (2012) reconoce comolas dos culturas: las Humanidades y las Ciencias Naturales.Focalizando esta distinción, proponemos reflexionar sobre laargumentación (...) escrita en dos disciplinas (Letras y Biología)desde la perspectiva toulminiana. Al respecto, consideramosque los argumentos y los modos de escribirlos están tanprofundamente ligados a las disciplinas que resulta esencialsaber y reconocer cómo operan estos procesos a fin de entenderla lógica de dichos campos. En efecto, las particularidades decada disciplina están siempre presentes a la hora de escribir yde argumentar por escrito. Todo texto pertenece, por lo menos,a un género y a una disciplina; como tal, emplea movimientosretóricos particulares que varían de comunidad en comunidady de un tipo de discurso a otro. Este trabajo, retoma lapropuesta de Toulmin (2003, 2001) y busca dar cuenta de lasespecificidades de la argumentación escrita en dos carrerasuniversitarias argentinas (Letras y Biología). Así, después dehaber efectuado un trabajo de campo que comprendió, duranteun semestre, observación participante de clases, entrevistasa docentes y alumnos y recolección de documentos áulicos(exámenes escritos y trabajos prácticos), distinguimos cuatrorasgos que caracterizan la argumentación en los ámbitosdisciplinares de las Humanidades y de las Ciencias Naturales:(1) los grados de formalidad; (2) los grados de precisión; (3) losmodos de resolución; y (4) las metas de la argumentación. Estoscuatro rasgos permiten complejizar los elementos estables delesquema toulminiano y pensar sus usos, sus aplicaciones y susalcances en las disciplinas. (shrink)

The goal of sociology, and all social science, is to produce reliable knowledge about human behavioral and social phenomena. To reach that goal, we undertake three kinds of activities: theoretical work, empirical work, and, even more basic, we develop frameworks that assemble the fundamental questions together with the fundamental tools that will be used to address them. This article examines the three sets of activities and their interrelations. Both deductive and nondeductive theory are highlighted, as are three kinds of empirical (...) work—testing the predictions of deductive theories, testing the propositions produced by nondeductive theories, and extratheoretical measurement and estimation. Illustrations are drawn from the fields of status, justice, and migration. (shrink)
