The concept of mental representation has long been considered to be central concept of philosophy of mind and cognitive science. But not everyone agrees. Neo-behaviorists aim to explain the mind without positing any representations. My aim here is not to assess the merits and demerits of neo-behaviorism, but to take their challenge seriously and ask the question: What justifies the attribution of representations to an agent? Both representationalists and neo-behaviorists tend to take it for granted that the real question about (...) representations is whether we should be realist about the theory of representationalism. This paper is an attempt to shift the emphasis from the debate concerning realism about theories to the one concerning realism about entities. My claim is that regardless of whether we are realist about representational theories of the mind, we have compelling reasons to endorse entity realism about mental representations. (shrink)

The debate over whether cognitive science is committed to the existence of neural representations is usually taken to hinge on the status of representations as theoretical posits: it depends on whether or not our best-supported scientific theories commit us to the existence of representations. Thomson and Piccinini (2018) and Nanay (2022) seek to reframe this debate to focus more on scientific experimentation than on scientific theorizing. They appeal to arguments from observation and manipulation to propose that experimental cognitive neuroscience gives (...) us non-theoretical reasons to be ontologically committed to representations. In this paper, I challenge their claims about observation and manipulation, and I argue that the question of whether we are ontologically committed to representations is still best understood as a question about the level of support we have for our representation-positing scientific theories.

The concept of mental representation has long been considered to be central concept of philosophy of mind and cognitive science. But not everyone agrees. Neo-behaviorists aim to explain the mind (or some subset thereof) without positing any representations.

Both representationalists and neo-behaviorists tend to take it for granted that (...) the real question about representations is whether we should be realist about the theory of representationalism.

This dissertation is about human knowledge of reality. In particular, it argues that scientific knowledge is bounded by historically available instruments and theories; nevertheless, the use of several independent instruments and theories can provide access to the persistent potentialities of reality. The replicability of scientific observations and experiments allows us to obtain explorable evidence of robust entities and properties. The dissertation includes seven chapters. It also studies three cases – namely, Higgs bosons and hypothetical Ϝ-particles (section 2.4), the Ptolemaic and (...) Kepler model of the planets (section 6.7), and the special theory of relativity (chapter 7). -/- Chapter 1 is the introduction of the dissertation. Chapter 2 clarifies the notion of the real on the basis of two concepts: persistence and resistance. These concepts enable me to explain my ontological belief in the real potentialities of human-independent things and the implications of this view for the perceptual and epistemological levels of discussion. On the basis of the concept of “overlapping perspectives”, chapter 3 argues that entity realism and perspectivism are complementary. That is, an entity that manifests itself through several experimental/observational methods is something real, but our knowledge of its nature is perspectival. Critically studying the recent views of entity realism, chapter 4 extends the discussion of entity realism and provides a criterion for the reality of property tokens. Chapter 5, in contrast, develops the perspectival aspects of my view on the basis of the phenomenological-hermeneutical approaches to the philosophy of science. This chapter also elaborates my view of empirical evidence, as briefly expressed in sections 2.5 and 4.5. Chapter 6 concerns diachronic theoretical perspectives. It first explains my view of progress, according to which current perspectives are broader than past ones. Second, it argues that the successful explanations and predictions of abandoned theories can be accounted for from our currently acceptable perspectives. The case study of Ptolemaic astronomy supports the argument of this chapter. Chapter 7 serves as the conclusion of the dissertation by applying the central themes of the previous chapters to the case study of special relativity theory. I interpret frame-dependent properties, such as length and time duration, and the constancy of the speed of light according to realist perspectivism. (shrink)

Implicit attitudes are the unconscious and automatic evaluations people make about objects, persons, and groups. These attitudes have been the subject of much discussion in the social and cognitive psychology literature of the past three decades. This paper explores whether it is justified to hold that implicit attitudes, seen as theoretical entities posited by empirical psychology, are real. We approach this question by drawing on the realism-antirealism debate in philosophy of science. To this end, we compare implicit attitudes with commonsense (...) belief/desire psychology, which, among other things, deploys explicit attitudes to explain behavior. We argue that the traditional arguments for and against realism about commonsense psychology do not apply to the case of implicit attitudes. However, we mount an alternative argument for realism about implicit attitudes, based on the criteria offered by entity realism, namely modifiability, non-redundancy, and robustness. We show that this framework is nicely applicable to implicit attitudes. However, it does not yet justify our belief in these attitudes. In order to take implicit attitudes as real within this entity realist approach, the reproducibility of each implicit measure as well as the correlation between different measures must be increased.

This review provides an outline of the collection New Approaches to Scientific Realism, edited by Wenceslao Gonzalez. In particular, it questions whether the contributions to this edition can claim to be novel. The edition includes an introductory chapter and eighteen texts by well-known philosophers, such as Peter Achinstein, Alexander Bird, Donald Gillies, Theo Kuipers, Alan Musgrave, Thomas Nickles, Ilkka Niiniluoto, Howard Sankey, and John Worrall.

Dark matter in astrophysics offers a rare treat for philosophers of science. When they look at the contemporary science of dark matter, they see reports of a widely accepted theoretical posit indispensable to our best theories and models but without an accepted experimental confirmation of its existence. Nearly all astrophysicists and cosmologists believe that dark matter exists and makes up approximately a quarter of the mass-energy content of the universe. However, they seem to know almost nothing about its nature, cannot (...) directly observe it, and have been unable to detect the products of any interactions with any of the candidate dark matter particles. This project addresses the apparent tension between the impressive knowledge taken to have been obtained in contemporary sciences of the cosmos and the methodological and theoretical limitations in obtaining such knowledge. To do so, this dissertation investigates the ways in which astronomers and astrophysicists are making progress by looking more closely at their experimental practices and actual theoretical commitments. More specifically, the goal is to determine how this bears on longstanding philosophical questions of scientific realism and the nature of scientific experimentation. Ultimately, I argue that astronomers do conduct traditional, interventionist experiments and that we can be realists about dark matter. These two views offer a way of thinking differently about how scientists can and do obtain knowledge about inaccessible and unobservable targets systems. -/- . (shrink)

This paper offers a pragmatist interpretation of Ian Hacking’s version of entity realism, and shows that such an interpretation enables the view to withstand a number of objections. Specifically, the paper shows Hacking’s rejection of a representationalist epistemology, which realist critics unjustifiably attribute to him, and shows his endorsement of a Deweyan pragmatist epistemology instead. If the interpretation is correct, the objections (a) that entity manipulation is theory-laden, (b) that the concept of home truths cannot do the work Hacking envisioned, (...) (c) that entity realism is a form of inference to the best explanation (IBE), (d) that some real entities aren’t manipulable, and (e) that some non-real entities are manipulable, lose much of their force. Objections (a), (b), and (c) rest on a metaepistemological misunderstanding, while objections (d) and (e) are addressed with (pragmatist) clarifications. This paper also offers a novel pragmatist argument for entity realism: the argument from technology. The argument from technology maintains that the reality of the entities that constitute our technologies is a precondition for those technologies’ meaningful use. In this case, entity realism remains a more viable perspective on science than is commonly acknowledged. (shrink)
