I consider the broad perspectives in biology known as ‘functionalism’ and ‘structuralism’, as well as a modern version of functionalism, ‘adaptationism’. I do not take a position on which of these perspectives is preferable; my concern is with the prior question, how should they be understood? Adapting van Fraassen’s argument for treating materialism as a stance, rather than a factual belief with propositional content, in the first part of the paper I offer an argument for construing functionalism and structuralism as (...) stances also. The argument draws especially on Gould’s insights concerning functionalism and structuralism, in particular their apparent historical continuity from the pre-Darwinian period through to today. In the second part of the paper I consider Godfrey-Smith’s distinction between empirical and explanatory adaptationism, and suggest that while the former is an empirical scientific hypothesis, the latter is closely related to the functionalist stance.

Since van Fraassen first put forward the suggestive idea that many philosophical positions should be construed as ‘stances’ rather than factual beliefs, there have been various attempts to spell out precisely what a philosophical stance might be, and on what basis one should be adopted. In this paper I defend a particular account of stances, the view that they are pragmatically justified perspectives or ways of seeing the world, and compare it to some other accounts that have been offered. In (...) Sect. 2 I consider van Fraassen’s argument for construing empiricism as a stance, and look at some responses to it. In Sect. 3 I outline my conception of stances as perspectives or ways of seeing, and explain how stances so understood may be justified. I illustrate this conception by way of a discussion of the model pluralist position with respect to the units of selection debate in biology, and suggest that on the model pluralist view different perspectives on the units of selection, such as the gene’s eye view, are in fact van Fraassian stances. In Sect. 4 I discuss the view put forward by Teller and Chakravartty among others that stances should be understood as epistemic policies, and argue that it is consistent with the conception of stances as perspectives. In the final section I criticise Rowbottom’s attempt to assimilate stances to Kuhnian paradigms. I argue that he has overlooked some important disanalogies between stances and paradigms, so that the comparison obscures more than it reveals. (shrink)

This paper argues that talk of ‘the aim of science’ should be avoided in the philosophy of science, with special reference to the way that van Fraassen sets up the difference between scientific realism and constructive empiricism. It also argues that talking instead of ‘what counts as success in science as such’ is unsatisfactory. The paper concludes by showing what this talk may be profitably replaced with, namely specific claims concerning science that fall into the following categories: descriptive, evaluative, normative, (...) and definitional. There are two key advantages to this proposal. First, realism and its competitors may be understood to consist of highly nuanced variants. Second, scientific realism and its competitors may be understood as something other than ‘all or nothing’ theses about science. More particularly, one may accept that there are general claims concerning science in some of the identified categories, but deny that there are such claims in the others. (shrink)

En este trabajo, nos proponemos redefinir las posturas que toman parte en el debate entre realismo y antirrealismo científicos, dejando de concebirlas únicamente como doctrinas o teorías que describen cómo es el mundo. En cambio, acorde al camino iniciado por van Fraassen en The empirical stance, optamos por definirlas como stances: políticas, estrategias o perspectivas a partir de las cuales construimos creencias fácticas. Así, en primera instancia nos dedicamos a entender qué es una stance y cómo caracterizar esta noción. En (...) segundo lugar, exploramos metodologías y enfoques para tratar el realismo y el antirrealismo como stances, y, en esta clave, definirlos adecuadamente. Por último, examinamos el impacto de esta propuesta en la explicación de los acuerdos y desacuerdos en el debate, evaluando los grados de afinidad o distancia en las perspectivas en juego. (shrink)

There is a deeply entrenched view in philosophy and physics, the closed systems view, according to which isolated systems are conceived of as fundamental. On this view, when a system is under the influence of its environment this is described in terms of a coupling between it and a separate system which taken together are isolated. We argue against this view, and in favor of the alternative open systems view, for which systems interacting with their environment are conceived of as (...) fundamental, and the environment's influence is represented via the dynamical equations that govern the system's evolution. Taking quantum theories of closed and open systems as our case study, and considering three alternative notions of fundamentality: (i) ontic fundamentality, (ii) epistemic fundamentality, and (iii) explanatory fundamentality, we argue that the open systems view is fundamental, and that this has important implications for the philosophy of physics, the philosophy of science, and for metaphysics.

Van Fraassen’s view that many philosophical positions should be understood as stances rather than factual beliefs with propositional content, has become increasingly popular. But the precise relation between a philosophical stance, and the factual beliefs that typically accompany it, is an unresolved issue. It is widely accepted that no factual belief is sufficient for holding a particular stance, but some have argued that holding certain factual beliefs is nonetheless necessary for adopting a given stance. I argue against this claim, along (...) with the weaker claim that while there are no beliefs that are necessary for adopting a particular stance, those who share a stance must share some characteristic belief(s) in common. I outline and defend an alternative ‘cluster’ account, according to which, in order to accept a stance, one must hold some minimal subset of the set of theoretical beliefs characteristic of the stance in question. This view can accommodate the intuitions motivating those who defend the stronger necessity claims, while crucially allowing for the flexibility of a stance vis-à-vis the relevant factual beliefs, and its relative independence from those beliefs, which is central to van Fraassen’s main examples of stances and their nature.

Kuhn’s view of science is as follows. Science involves two key phases: normal and extraordinary. In normal science, disciplinary matrices (DMs) are large and pervasive. DMs involve “beliefs, values, techniques, and so on shared by the members of a given community” (Kuhn 1996, 175). “And so on” is regrettably vague, but Kuhn (1977, 1996) mentions three other key elements: symbolic generalizations (such as F=dp/dt), models (such as Bohr’s atomic model), and exemplars. These components of DMs overlap somewhat. For instance, symbolic (...) generalizations may feature in techniques and beliefs, and models may exhibit values. To be a (genuine) scientist, in the normal science phase, is to puzzle solve within the boundaries of the DM. It is to buy into the ruling dogma (Kuhn 1963) and to accept that “failure to achieve a solution discredits only the scientist ... ‘It is a poor carpenter who blames his tools’” (Kuhn 1996, 80). Puzzle solving involves a wide variety of activities, including. (shrink)

The present paper aims at highlighting some of the main characteristics of a descriptive contextual approach to philosophy. Descriptive, in the sense that it centers not on the question of what philosophy should be, but on what philosophy is, has been, or may be. And contextual, in the sense that it treats philosophy as human praxis situated in and interacting with certain social and historical settings. In order to develop such an account, we engage closely with Kuhn’s paradigm-centered contextual approach (...) to science and examine, following Rorty, how it could be regarded in connection to philosophy. The paper concludes with a brief discussion of two concrete cases to which such an approach may be applied, the division between analytic and continental philosophy at the level of philosophical traditions, and the case of Wittgenstein’s life and thought at the level of individual philosophers.

Popper repeatedly emphasised the significance of a critical attitude, and a related critical method, for scientists. Kuhn, however, thought that unquestioning adherence to the theories of the day is proper; at least for ‘normal scientists’. In short, the former thought that dominant theories should be attacked, whereas the latter thought that they should be developed and defended (for the vast majority of the time). -/- Both seem to have missed a trick, however, due to their apparent insistence that each individual (...) scientist should fulfil similar functions (at any given point in time). The trick is to consider science at the group level; and doing so shows how puzzle solving and ‘offensive’ critical activity can simultaneously have a legitimate place in science. This analysis shifts the focus of the debate. The crucial question becomes ‘How should the balance between functions be struck?’. (shrink)

It is widely acknowledged that metaphysical assumptions, commitments and presuppositions play an important role in science. Yet according to the empiricist there is no place for metaphysics as traditionally understood in the scientific enterprise. In this paper I aim to take a first step towards reconciling these seemingly irreconcilable claims. In the first part of the paper I outline a conception of metaphysics and its relation to science that should be congenial to empiricists, motivated by van Fraassen’s work on ‘stances’. (...) There has been a considerable amount of recent work devoted to van Fraassen’s ‘stance’ view, but it has not on the whole been noticed that the view has the potential to motivate a general empiricist conception of the relation between science and metaphysics. In the second and third sections I discuss two examples from biology to illustrate this conception: metaphysical punctuationism, and its relation to and influence on the thesis of punctuated equilibrium; and dialectical biology as defended by Levins and Lewontin.

The aim of this paper is to establish a substantial positive philosophical connection between Bas van Fraassen and Hegel, by focusing on their respective notions of ‘stance’ and ‘form of consciousness’. In Section I, I run through five ways of understanding van Fraassen’s idea of a stance. I argue that a ‘stance’ is best understood as an intellectual disposition. This, in turn, means that the criteria for assessing a stance are ones which ask whether or not a stance adequately makes (...) sense of things. In Section II, the discussion turns to Hegel’s notion of a ‘form of consciousness’. I argue that Hegel’s notion of a ‘form of consciousness’ is best understood as comprising a worldview. The principal advantage of articulating stances in a Hegelian way is that such an interpretation improves on the previous five ways of understanding stances. This is because a form of consciousness explicitly details both the theoretical and affective attitudes that van Fraassen is after. Therefore, why Hegel is potentially a better source of understanding stances than the other accounts is that forms of consciousness most clearly illustrate the pragmatist elements of a stance.

In this piece, I advocate and motivate a new understanding of thought experiments, which avoids problems with the rival accounts of Brown and Norton.

This paper is a supplement to, and provides a proof of principle of, Kuhn vs. Popper on Criticism and Dogmatism in Science: A Resolution at the Group Level. It illustrates how calculations may be performed in order to determine how the balance between different functions in science—such as imaginative, critical, and dogmatic—should be struck, with respect to confirmation (or corroboration) functions and rules of scientific method.

Thomas S. Kuhn is famous both for his work on the Copernican Revolution and his ‘paradigm’ view of scientific revolutions. But Kuhn later abandoned the notion of paradigm in favour of a more ‘evolutionary’ view of the history of science. Kuhn’s position therefore moved closer to ‘continuity’ models of scientific progress, for instance ‘chain-of-reasoning’ models, originally championed by D. Shapere. The purpose of this paper is to contribute to the debate around Kuhn’s new ‘developmental’ view and to evaluate these competing (...) models with reference to some major innovations in the history of cosmology, from Copernicanism to modern cosmology. This evaluation is made possible through some unexpected overlap between Kuhn’s earlier discontinuity model and various versions of the later continuity models. It is the thesis of this paper that the ‘chain-of-reasoning’ model accounts better for the cosmological evidence than both Kuhn’s early paradigm model and his later developmental view of the history of science.
