James Ladyman has argued that constructive empiricism entails modal realism, and that this renders constructive empiricism untenable. We maintain that constructive empiricism is compatible with modal nominalism. Although the central term 'observable' has been analyzed in terms of counterfactuals, and in general counterfactuals do not have objective truth conditions, the property of being observable is not a modal property, and hence there are objective, non-modal facts about what is observable. Both modal nominalism and constructive empiricism require clarification in the face (...) of Ladyman's argument. But we also argue that, even if Ladyman were right that constructive empiricism entails modal realism, this would not be a problem for constructive empiricism. (shrink)

, I argued that Bas van Fraassen's constructive empiricism was undermined in various ways by his antirealism about modality. Here I offer some comments and responses to the reply to my arguments by Bradley Monton and van Fraassen [2003]. In particular, after making some minor points, I argue that Monton and van Fraassen have not done enough to show that the context dependence of counterfactuals renders their truth conditions non-objective, and I also argue that adopting modal realism does after all (...) undermine the motivation for constructive empiricism.

In their recent “A modest defense of manifestationalism” (2015), Asay and Bordner defend this position from a quite famous criticism put forward by Rosen (1994), according to which while manifestationalism can be seen as more compatible with the letter of empiricism than other popular stances, such as constructive empiricism, it fails nonetheless to make sense of science. The two authors reckon that Rosen’s argument is actually flawed. In their view, manifestationalism could in fact represent a legitimate thesis about the nature (...) of scientific inquiry. In this paper, I will show that Asay and Bordner’s criticisms to Rosen are actually off target. Moreover, they rest upon an understanding of what the aim of science is that might serve to their purposes, but that does not seem to be in line with the scientific enterprise. Perhaps constructive empiricism still represents the best compromise so far presented between strict empiricism and the acknowledgment of the rationality of science. (shrink)

It has become apparent that the debate between scientific realists and constructive empiricists has come to a stalemate. Neither view can reasonably claim to be the most rational philosophy of science, exclusively capable of making sense of all scientific activities. On one prominent analysis of the situation, whether we accept a realist or an anti-realist account of science actually seems to depend on which values we antecedently accept, rather than our commitment to “rationality” per se. Accordingly, several philosophers have attempted (...) to argue in favour of scientific realism or constructive empiricism by showing that one set of values is exclusively best, for anyone and everyone, and that the downstream choice of the philosophy of science which best serves those values is therefore best, for anyone and everyone. These efforts, however, seem to have failed. In response, I suggest that philosophers of science should suspend the effort to determine which philosophy of science is best for everyone, and instead begin investigating which philosophy of science is best for specific people, with specific values, in specific contexts. I illustrate how this might be done by briefly sketching a single case study from the history of science, which seems to show that different philosophies of science are better at motivating different forms of scientific practice.

This paper concerns the rational reconstruction of physical theories initially advanced by F. P. Ramsey and later elaborated by Rudolf Carnap. The Carnap–Ramsey reconstruction of theoretical knowledge is a natural development of classical empiricist ideas, one that is informed by Russell's philosophical logic and his theories of propositional understanding and knowledge of matter ; as such, it is not merely a schematic representation of the notion of an empirical theory, but the backbone of a general account of our knowledge of (...) the physical world. Carnap–Ramsey is an illuminating approach to epistemological problems that remain with us, one whose difficulties are shared by accounts that have sought to replace it. 1 Introduction 2 Russell's theory of propositional understanding 3 Ramsey's primary and secondary systems 4 Carnap's reconstruction of the language of science and an observation of Newman 5 Extension of the foregoing to constructive empiricism 6 Putnam's model-theoretic argument and the semantic view of theories 7 The problem clarified and resolved.

According to Bas van Fraassen, scientific realists and anti-realists disagree about whether accepting a scientific theory involves believing that the theory is true. On van Fraassen’s own anti-realist empiricist position, accepting a theory involves believing only that the theory is correct in its claims about observable aspects of the world. However, a number of philosophers have argued that acceptance and belief cannot be distinguished and thus that the debate is either confused or trivially settled in favor of the realist. In (...) addition, another set of philosophers have argued that van Fraassen’s empiricist position appeals to an unmotivated distinction between observable and unobservable aspects of the world. This paper aims to reconstruct a van Fraassen-style empiricism about scientific acceptance that avoids these two objections – reconstructed empiricism. (shrink)

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)

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.

Van Fraassen has argued that many philosophical positions should be understood as stances rather than factual beliefs. In this paper I discuss the vexed question of whether and how such stances can be rationally justified. Until this question has been satisfactorily answered, the otherwise promising stance approach cannot be considered a viable metaphilosophical option. One can find hints, and the beginnings of an answer to this question, in van Fraassen’s (and others’) writings, but no general, fully clear and convincing account (...) has been offered. I aim to provide such an account. In the first section I introduce the concept of a stance. In the second section I argue that stances may be justified pragmatically, in terms of both their epistemic fruits, and their coherence with values. In the third section I further consider the relationship between stances and values, arguing that the value-ladenness of a stance does not render it immune to rational scrutiny. In the final section I look at van Fraassen’s version of epistemological voluntarism, which plays a central role in his conception of the basis on which a stance may be rationally adopted. I show that voluntarism provides a theoretical framework, and approach to epistemology, within which the forms of justification appropriate to stance choice I outline in sections 2 and 3 find a natural home.

We report the results of a study that investigated the views of researchers working in seven scientific disciplines and in history and philosophy of science in regard to four hypothesized dimensions of scientific realism. Among other things, we found that natural scientists tended to express more strongly realist views than social scientists, that history and philosophy of science scholars tended to express more antirealist views than natural scientists, that van Fraassen’s characterization of scientific realism failed to cluster with more standard (...) characterizations, and that those who endorsed the pessimistic induction were no more or less likely to endorse antirealism.

As the debate between realists and empiricists in the philosophy of science drags on, one point of consensus has emerged: no one wants to be a manifestationalist. The manifestationalist is a kind of radical empiricist who argues that science provides theories that aim neither at a true picture of the entire world, nor even an empirically adequate picture that captures the world in all its observable respects. For manifestationalists, science aims only at providing theories that are true to the observed (...) aspects of reality. If the guiding idea of empiricism is that experience, and experience alone, provides us with knowledge about the world, then manifestationalism is an exceptionally strict empiricist perspective on science. Manifestationalism has primarily served within a reductio: certain empiricist views and arguments, when taken to their logical conclusion, lead to manifestationalism and so cannot be correct. The reductio works only because manifestationalism is widely agreed to be a non-starter. However, this consensus against manifestationalism is based on a single argument. We contest this assessment of manifestationalism and show that the primary argument against manifestationalism fails to hit its target. We do not intend to offer a manifesto for manifestationalism. Rather, we aim to vindicate it from a false accusation. Manifestationalism may not be the correct view of science, but the objections levied against it so far can be met. (shrink)

Faced with interminable combat over some piece of philosophical terrain, someone will inevitably suggest that the contested ground is nothing more than a philosophically manufactured mirage that is therefore not worth fighting for. Arthur Fine has long advocated such a response—the ‘Natural Ontological Attitude,’ or NOA—to the realism debate in the philosophy of science. Notwithstanding the prima facie incompatibility between the realist’s and anti-realist’s positions, Fine suggests that there is in fact enough common ground for NOA to stand on its (...) own as a minimal alternative, one that enjoys the advantage of being free of the philosophical burdens of its overweight contenders.

Bas van Fraassen claims that constructive empiricism strikes a balance between the empiricist’s commitments to epistemic modesty – that one’s opinion should extend no further beyond the deliverances of experience than is necessary – and to the rationality of science. In “Should the Empiricist be a Constructive Empiricist?” I argued that if the constructive empiricist follows through on her commitment to epistemic modesty she will find herself adopting a much more extreme position than van Fraassen suggests. Van Fraassen and Bradley (...) Monton have recently responded. My purpose here is to contest their response. The goal is not merely the rebuttal of a rebuttal; there is a lesson to learn concerning the realist/anti-realist dialectic generated by van Fraassen’s view. (shrink)

Manifestationalism holds that science aims only to give us theories that are correct about what has been observed thus far. Several philosophers, including Bas van Fraassen, have argued that manifestationalism cannot make sense of the scientific impetus to make new observations, since such observations only risk turning manifestationally adequate theories into inadequate ones. This paper argues that a strikingly similar objection applies to van Fraassen’s own constructive empiricism, the view that science aims only to find theories that are empirically adequate. (...) Roughly, the objection is that constructive empiricism cannot make sense of the scientific impetus to expand the limits of what can be observed, since such expansions only risk turning empirically adequate theories into inadequate ones.

An explanatory gap ensues when the truths constituting the explanans do not entail the explanandum. Attempts to give a physicalist account of consciousness seem to generate an explanatory gap, which is special in the following psychological sense. In other cases, it is possible to bridge or close the gap by regimenting or eliminating the respective concepts. In the case of consciousness, however, there is a pervasive intuition that the gap remains even when one works out a notion of consciousness that (...) allows the entailment of truths about consciousness from physical premises. The intuition is expressed by the sense that something essential about consciousness is left out from any such conceptual regimentation. This paper defends the view that this intuition is generated by the way our experiences are given to us. Every experience has a component that is not captured by any specification. The gap intuition is due to this ineffable component in experiences. Since conscious experiences are partly ineffable, it seems that no account of consciousness captures conscious experiences entirely and so would develop the intuition that something has been left out. An alternative explanation to the gap intuition is provided by the “phenomenal concepts’ strategy”. According to this strategy, it is the peculiar nature of phenomenal concepts that feeds the intuition. The main problem with such an approach is that phenomenal concepts are more coarse-grained than the experiences themselves and thus their application still does not entail what it is like to have a particular phenomenal experience.
