There are realist and antirealist interpretations of the free energy principle (FEP). This paper aims to chart out a structural realist interpretation of FEP. To do so, it draws on Worrall’s (Dialectica 43(1–2): 99–124, 1989) proposal. The general insight of Worrall’s paper is that there is progress at the level of the structure of theories rather than their content. To enact Worrall’s strategy in the context of FEP, this paper will focus on characterising the formal continuity between fundamental equations of (...) thermodynamics—such as Boltzmann’s equation and Gibbs’s equation—on the one hand, and Friston’s characterisation of FEP on the other. Lack of a universal consensus on the physical character of entities that feature in thermodynamics, information theory and FEP notwithstanding, I argue that there is structural continuity and unity at the level of mathematical equations that regiment entropy, information and free energy. The existence of such structural continuity and unity provides grounds for structural realism about FEP. (shrink)

Metaphysicians of causation have long debated the existence of primitive causal modalities (e.g., powers), with reductionists and realists taking opposing stances. However, little attention has been given to the legitimacy of the metaphysical question itself, despite our longstanding awareness of Rudolf Carnap’s critique of metaphysics. This article develops a (broadly) Carnapian-pragmatist approach to causation as an alternative to existing metaphysical approaches. Within this pragmatist approach, metaphysical questions about causation are reinterpreted as practical questions about the choice of causal frameworks. To (...) motivate and justify this new approach, I argue that, in emphasizing the priority of ontology over methodology, metaphysical approaches to causation fail to adequately capture the interplay between causal ontology and causal methodology in scientific practice. In contrast, the Carnapian approach provides a more appealing alternative that emphasizes the mutual dependence and ‘balance’ between the two in an ongoing process of scientific inquiry. I use the recent controversy over ‘What counts as a cause’ in statistical causal inference as a case study to demonstrate how the Carnapian approach can help us better understand the role of ontological issues in methodological practices.

In this paper I argue that problems connected to good scientific practice and scientific misconduct can be fruitfully analyzed via the means of transaction costs economics. Thus, transaction costs economics is a valuable tool for the descriptive as well as normative analysis of science. I further argue that current institutional matrices impose high transaction costs on (potential) funding agencies of scientific research. This underlies many cases of bad practice in scientific research. Lowering these transaction costs would have positive effects both (...) on the adherence of researchers to the rules of good practice as well as for the amount of funding that is spend on research. In the end, I propose an institutional reform that promises to lower these transaction costs based upon an idea of Michael Rosenblatt. (shrink)

In this paper, I address the significance of the key notions of coordination, constitution and convention. My aim in so doing is to provide a better understanding of their relation to conventionalism and to evaluate the prospects for a version of the relativized a priori based on a refinement of the notion of coordination. I stress the Kantian roots of all three concepts. Moreover, I argue that the link between the early logical positivist requirement for the uniqueness of coordination and (...) the Kantian account of empirical objectivity provides an interpretive key that sheds light on the alleged incompatibility between constitutive principles and conventionalism.

The increasing popularity of artificial cognitive enhancements raises the issue of their impact on the agent’s personal autonomy, and issues pertaining to how the latter is to be secured. The extended mind thesis implies that mental states responsible for autonomous action can be partly constituted by the workings of cognitive artifacts themselves, and the question then arises of whether this commits one to embracing an extended agent thesis. My answer is negative. After briefly presenting the main accounts on the conditions (...) for autonomous agency, and analyzing how the latter can be protected from threats posed by the use of cognitive artifacts, I argue that autonomous agency is essentially tied to conscious experience and intentionality, which in turn can only be attributed to the human part of any extended cognitive system. I present both theoretical (conceptual) and practical arguments against recognizing the entire extended system, composed of one human and an artifact, as an autonomous agent. (shrink)

The use of fictional models is extensive and rewarding in modern science. This fact captured the attention of philosophers of science, who are focusing on questions such as the following: is it possible for a fictional model to be explanatory? And, if so, in virtue of what is such a fictional model explanatory? In this paper, I discuss these questions in relation to the realism vs. anti-realism debate in philosophy of science. I focus on work developed by Alisa Bokulich who (...) has argued for the explanatory role played by fictional models, claiming that it can be accommodated by realism in ‘a broad sense’. To this end, Bokulich introduced what she called ‘an eikonic conception’ of explanation, as opposed to the so-called ‘ontic’ conception. This move, Bokulich claims, allows non-causal explanations to be acceptable to a modified version, as opposed to a ‘naïve’ brand of realism. Roughly, a fictional model can capture aspects of reality if it manages to act as a proxy for a theory targeting a physical system. As Bokulich explains with the example of James Clerk Maxwell’s use of mechanical models, this is due to structural correspondences between a model and a theory at a certain level of abstraction. However, Bokulich does not explain how the model grasps reality. In this paper, I fill this missing piece of the puzzle. While I agree with Bokulich on the explanatory function of fictional models, I shall invoke her reading of Maxwell’s work to draw a different conclusion. Specifically, I argue that structural correspondences at various levels form what I call ‘a ladder of abstractions’ which connects aspects of a target system to the corresponding depths of descriptions. Modifying in these terms the scope of ‘representing a system’, I suggest that Bokulich’s proposed modification of realism is obviated. (shrink)

The label realist in the debate about natural kinds can imply different things. Many authors in this debate subscribe to views that are in some way realist, but without making clear whether the realism in question specifically attaches to kind categories or something else. The traditional understanding of realism about natural kinds is stated in terms of the mind-independence criterion. However, a recent tendency in the debate is to reject this understanding on the ground of its incompatibility with naturalistic approaches (...) to natural kinds. The aim of this paper is to disentangle different meanings attached to the term realism about natural kinds and examine arguments for rejecting the traditional mind-independence framing of the debate. I recommend the reestablishment of mind-independent realism as a legitimate contender for naturalist approaches to natural kinds by indicating that mind-independent realists have at their disposal all the resources to subscribe to such an approach. I proceed by showing how keeping the traditional distinction between realist and antirealist views in terms of mind-independence allows us to keep track of important distinctions between different accounts of natural kinds which are otherwise blurred. Then I examine the arguments against this traditional framing and conclude that they either (1) rest on a conflation between mind-independence of kinds versus entities belonging to kinds, or (2) unjustifiably presuppose that mind-independent realists do not have resources to uphold a naturalistic view of natural kinds.

Bas van Fraassen’s Darwinian explanation for the success of science has sparked four decades of discussion, with scientific realists and antirealists alike using biologically inspired reasoning to support their points of view. Based on critical engagement with van Fraassen’s proposal itself and later contributions by Stathis Psillos and K. Brad Wray, we claim that central arguments on both sides of this controversy suffer from an insufficient understanding of Darwinism and its underlying biological concepts. Adding the necessary biological background turns out (...) to subvert the argumentative force of viewing the success of scientific theories as analogous to the behaviour of biotic entities. In conclusion, we sketch more productive ways of viewing the relationship between biology and scientific realism. (shrink)

In There Are No Such Things As Theories (French 2020), the reification of theories is critically analysed and rejected. My aim here is to tease out some of the implications of this approach first of all, for how we, philosophers of science, should view the history of science; secondly, for how we should understand the devices that we use in our own philosophical practices; and thirdly, for how we might think about the relationship between the history of science and the (...) philosophy of science.

In this paper, it is argued that, contrary to some suggestions in the philosophical literature, dispositions cannot replace laws in the description of the physical world. If for a certain type of physical situation a well-working law-based account is available, then it is not possible to describe that situation equally well in terms of dispositions. Using an example consisting of four laws (Coulomb’s law, Newton’s law of gravitation, the rule for the composition of forces and Newton’s second law), it is (...) shown that when one attempts to replace a law-based account with a disposition-based account, the latter turns out to be either less informative or inferior with respect to theoretical virtues, such as simplicity, unification, non-triviality of predictions and explanatory power. Laws are also better suited to deal with interactions and their screening off. Using inference to the best explanation, one can conclude from this comparison that it is laws rather than dispositions that should be included in our ontological picture of nature. (shrink)

The existing philosophical views on what is the meaning of causality adequate to medicine are vastly divided. We approach this question and offer two arguments in favor of pluralism regarding concepts of causality. First, we analyze the three main types of research designs (randomized-controlled trials, observational epidemiology and laboratory research). We argue, using examples, that they allow for making causal conclusions that are best understood differently in each case (in agreement with a version of manipulationist, probabilistic and mechanistic definitions, respectively). (...) Second, we analyze clinical practice and argue that these manipulationist, probabilistic and mechanistic causal claims can be used as evidence for different therapeutic decisions. We differentiate among ‘predicting’ that does not change the relata of causal claims, (mechanistic) ‘interferences’, and ‘interventions’ in the strict sense that act on causes to change effects. The central conclusion is that causal claims agreeing with diverse concepts of causality can deliver evidence for different types of therapeutic decisions. (shrink)

This paper connects veritistic teleological epistemology, VTE, with the epistemological dimension of the scientific realism debate. VTE sees our epistemic activities as a tradeoff between believing truths and avoiding error. I argue that van Fraassen’s epistemology is not suited to give a justification for a crucial presupposition of his Bad Lot objection to inference to the best explanation (IBE), the presupposition that believing that p is linked to p being more likely to be true. This makes him vulnerable to a (...) counterargument, tailored after Musgrave’s defense of IBE, which would result in a stalemate between them about presuppositions of rationality. I will, however, show that switching to VTE can justify van Fraassen’s presupposition. This leads to a dismissal of common IBE arguments for realism as presented by Boyd and Musgrave, but I also argue that a more cautious version of realism can be rescued from the Bad Lot objection. Finally, I raise some worries about epistemic risk-attitude consistency for constructive empiricists and develop an alternative anti-realist position.1. (shrink)

The Evolving Block Universe is a model where spacetime continuously emerges leading to a ‘growth’ of spacetime by which there is a passage of time. Its most recent version extends ideas on the passage of time and the various arrows of time (determined by the cosmological evolution of the whole universe). Attention is drawn to some principal problems with this model, especially how the present moment and the passage of time are defined.

In this paper, after presenting three challenges that any knowledge-based demarcation between science and non-science should meet, namely, the skeptical, triviality, and mimicry challenges, I show how a recent contender in epistemology, viz., presuppositional epistemic contextualism, allows these challenges to be met, hence pointing toward a novel solution to the perennial demarcation problem. Conceiving of scientific knowledge from the vantage point of contextualism forces us to consider science as being first and foremost a distinctive epistemological context, which has the peculiarity (...) of coming with a very high degree of stringency for the truth conditions of putative knowledge attributions. The fact that science imposes particularly stringent norms on knowledge is measured by the extension of the set of counterpossibilities that science is (i) in the business of eliminating on the basis of available evidence and (ii) ready to take seriously (insofar as they are consistent with the scientific community’s pragmatic presuppositions at a given time and place).

It has been widely discussed whether the existence of other universes than the known universe is a purely metaphysical consideration. This paper argues to the contrary that the existence of other universes is a meaningful hypothesis, which can be tested based on observable data. The paper applies the perspective of observer bias as an approach for assigning probabilities to the mutually excluding hypotheses of universe vs. multiverse, i.e., whether the known universe is the only universe, or just one universe in (...) an ensemble of universes, a so-called multiverse. The basic idea of the paper relies on the following consideration. In a multiverse, the vast majority of observers would live in universes that are more life friendly. Thus, conditional on there being a multiverse, we should expect to find ourselves in a universe with values of the fundamental parameters that provide particularly fertile grounds for life. In contrast, if there is only a single universe, it may well be the case that there is still a few observers even if the parameters are far from ideal for life, and in that case, those observers will find values of the parameters that are not ideal for intelligent life. It may well be the case that, among all parameter configurations that allow life at least somewhere, those that are not ideal for life far outnumber those that are ideal for life. Based on this elementary consideration, the paper proceeds to propose a quantitative framework to determine probabilities for either hypothesis. In particular, it is described how a future ab initio determination of some of the factors in the Drake equation may be used to infer which one of the two hypotheses is the more likely. A quantitative approach to this end is proposed. Expressing these factors of the Drake equation in the context of the two hypotheses, a general likelihood approach is first described. Then, to support intuition, example computations are provided, illustrating how an actual hypothesis test would work in practice. (shrink)

In this paper, I analyze some disagreements about scientific ontology as cases of disagreement between epistemic peers. I maintain that the particularities of these cases are better understood if epistemic peerhood is relativized to a perspective-like index of epistemic goals and values. Taking the debate on the metaphysics of laws of nature as a case study, I explore the limits and possibilities of a trans-perspective assessment of positions regarding scientific ontology.

The commentators in this Special Issue on ‘Epistemology, ontology, and scientific realism’ raise substantial questions about, and objections to, central aspects of my own thinking about semirealism (a proposal for how best to formulate scientific realism), as well as the larger philosophical context in which debates about scientific realism unfold. This larger context concerns the nature of realism more generally and the epistemic stances that underlie our considered opinions of what the sciences are telling us about the ontology of the (...) world. In this paper, I consider my critics’ remarks, and endeavor to lay their criticisms to rest. (shrink)

Contrary to empiricist hopes, Chakravartty claims that science cannot escape metaphysics. According to him, in line with the theory-ladenness thesis, science necessarily includes metaphysical presuppositions and metaphysical inferences. He contends that strong empiricism provides an implausible description of what scientists do. Furthermore, he claims, empiricists should recognize that in fact they entertain metaphysical beliefs. I analyze Chakravartty’s arguments and point out some significant weaknesses. Drawing on recent experimental results in the field of experimental psychology, I question the use of an (...) exaggerated theory-ladenness thesis and conclude that Chakravartty’s view concerning the relationship between science and metaphysics is far of successfully rebutting the empiricist proposals.

The article focuses on the unifying and explanatory power of the selective realism defended by Anjan Chakravartty. Our main aim is twofold. First, we critically analyse the purported synthesis between entity realism and structural realism offered by the author. We give reasons to think that this unification is an inconvenient marriage. In the second step, we deal with certain controversial aspects of the intended unification among three metaphysical concepts: causation, laws of nature and natural kinds. After pointing out that Chakravartty’s (...) conception of laws is a plausible view that a scientific realist might endorse, we contend, on the contrary, that the concept of natural kind is dispensable in the framework of Chakravartty’s realism.

In _Scientific Ontology_, Chakravartty diagnoses a “dramatic conflict” between empiricism and metaphysics and aims to overcome that conflict by opting for a modern-day variant of Pyrrhonism, i.e. by appreciating the equal strength (_isostheneia_) of the arguments for and against the empiricist and metaphysical positions, and by achieving tranquility (_ataraxia_) by suspending judgment or remaining speechless in the face of that _isostheneia_. In this paper, I want to argue that instead of remaining speechless in the face of the _isostheneia_ of the (...) arguments for and against the empiricist and metaphysical positions, we should adopt a position that remains underrated in Chakravartty’s analysis: a position that amounts to a modern-day variant of the Kantian combination of transcendental idealism and empirical realism, and that like the original Kantian combination, is capable of solving many instances of the dramatic conflict between empiricism and metaphysics and, in particular, a conflict that is the talk of the town in philosophy of science these days—the conflict between ontic-structural realism and Lewisian metaphysics.

Chakravartty puts forward a view of scientific knowledge that conceives of properties attributed to objects by scientific models as dispositions. Those dispositions refer to the capacity of an object to behave differently in different circumstances. This pluralism of behaviour is intended to show that perspectivalism does not exclude the possibility of non-perspectival knowledge. To support this claim, he offers an analogy between conflicting models and contrastive explanations. I examine the strength of the purported analogy between conflicting models and contrastive explanations. (...) Then, I analyse this dispositionalist account of properties in order to assess whether ontological pluralism can meet the challenge that conflicting models pose to the scientific realism. To conclude, I contend that to accomplish this goal, a more detailed account of dispositional properties should be provided, as well as a theory of explanatory relevance. (shrink)

Logic diagrams have been increasingly studied and applied for a few decades, not only in logic, but also in many other fields of science. The history of logic diagrams is an important subject, as many current systems and applications of logic diagrams are based on historical predecessors. While traditional histories of logic diagrams cite pioneers such as Leibniz, Euler, Venn, and Peirce, it is not widely known that Kant and the early Kantians in Germany and England played a crucial role (...) in popularising Euler(-type) diagrams. In this paper, the role of the Kantians in the late eighteenth and early nineteenth centuries will be analysed in more detail. It shows that diagrams (or intuition in general) were a highly contentious topic that depend on the philosophical attitude and went beyond logic to touch on issues of physics, metaphysics, linguistics and, above all, mathematics.

In a response to my recent article in this journal, Shahram Shahryari argues that I fail to present a third position between absolutism and relativism. He makes two points: first, that fallibilism is insufficient as an alternative, because it is compatible with both relativism and absolutism. The second point is that my argument that experience can lead to objective judgment without being a new absolute fails. I discuss these in turn, showing that both critiques fail and that pragmatism is a (...) genuine alternative between absolutism and relativism. (shrink)

The chemist Jeremias Benjamin Richter (1762–1807) coined the term “stoichiometry” and proposed the “law of definite proportions.” He is also commonly acknowledged as having been a student of Immanuel Kant (1724–1804). This paper demonstrates how Kant’s philosophy positively shaped Richter’s approach to chemistry in the _Anfangsgründe der Stöchiometrie_ (1792–1794) and outlines two ways in which Richter attempted to represent the chemical force in “pure intuition”: (1) “reductionistic forces,” in which qualitative features scale with the quantity of matter; and (2) generalized (...) “abstracted forces,” in which a plurality of dissolution- and bonding-properties are latent within the chemical in the manifold of space-time.

The present paper probes the relation between the metaphysics of human freedom and the Rothbardian branch of Austrian economics. It transpires that Rothbard and his followers embrace metaphysical libertarianism, which holds that free will is incompatible with determinism and that the thesis of determinism is false as pertaining to human action. However, as we demonstrate, their economics with its reliance on value scales requires for its tenability compatibilist freedom. Moreover, we attempt to show that the notion of value scales (or (...) preferences) postulated by them implies that value scales are determinative of choices people make. We contend that it is for this reason that the said Austrians should jettison their metaphysical libertarianism. (shrink)

The concept of downward causation is frequently used in an explanatory capacity in biology to account for certain regularities and processes. Some philosophers, however, argue that downward causation is metaphysically incoherent, providing three main objections. Underlying these objections is the assumption that entities are connected by compositional hierarchies of levels of organization. In this paper, I introduce the notions of weak and strong compositional relations using examples from evolutionary developmental biology. I argue that downward causation becomes unproblematic if we use (...) features of interventionist theories of causation to explain the causal relations between levels. I show that an interventionist account of downward causation successfully responds to the three central objections to downward causation in the philosophical literature and I clarify the explanatory usefulness of the concept in biology. As such, this paper provides an epistemic solution to demystify downward causation in the context of scientific practice. The solution proposed is compatible with how biologists seem to use a concept of downward causation fruitfully in their work. (shrink)

Penrose's conformal cyclic cosmology describes the cosmos as a collection of successive universes, the so-called aeons. The beginning and ending of our universe are directly connected to two other, anterior and posterior, universes. Penrose considers but rules out a different interpretation of conformal cyclic cosmology: that the beginning of our universe is connected to its own end in a cosmic loop. The paper argues that the view, aeon monism, should be regarded as a natural interpretation of conformal cyclic cosmology and (...) discusses its implications for the concept of eternal return in light of the most popular metaphysics of time.

Preparing general relativity for quantization in the Hamiltonian approach leads to the `problem of time,' rendering the world fundamentally timeless. One proposed solution is the `thermal time hypothesis,' which defines time in terms of states representing systems in thermal equilibrium. On this view, time is supposed to emerge thermodynamically even in a fundamentally timeless context. Here, I develop the worry that the thermal time hypothesis requires dynamics -- and hence time -- to get off the ground, thereby running into worries (...) of circularity. (shrink)

The paper discusses the possible implications of the relational framework of Pure Shape Dynamics for the metaphysics of time. The starting point of the analysis is an interpretation of shapes in ontic structural realist terms, which gives rise to the notion of self-subsisting structure. The relational version of a Newtonian-particle toy model is introduced and discussed as a concrete example.
