Concepts as Semantic Pointers: A Framework and Computational Model

The reconciliation of theories of concepts based on prototypes, exemplars, and theory‐like structures is a longstanding problem in cognitive science. In response to this problem, researchers have recently tended to adopt either hybrid theories that combine various kinds of representational structure, or eliminative theories that replace concepts with a more finely grained taxonomy of mental representations. In this paper, we describe an alternative approach involving a single class of mental representations called “semantic pointers.” Semantic pointers are symbol‐like representations that result from the compression and recursive binding of perceptual, lexical, and motor representations, effectively integrating traditional connectionist and symbolic approaches. We present a computational model using semantic pointers that replicates experimental data from categorization studies involving each prior paradigm. We argue that a framework involving semantic pointers can provide a unified account of conceptual phenomena, and we compare our framework to existing alternatives in accounting for the scope, content, recursive combination, and neural implementation of concepts.     

From rocks to graphs — the shaping of phenomena

Assuming an essential difference between scientific data and phenomena, this paper argues for the view that we have to understand how empirical findings get transformed into scientific phenomena. The work of scientists is seen as largely consisting in constructing these phenomena which are then utilized in more abstract theories. It is claimed that these matters are of importance for discussions of theory choice and progress in science. A case study is presented as a starting point: paleomagnetism and the use of paleomagnetic data in early discussions of continental drift. Some general features of this study are presented in formalized language. It is suggested that the presentation given is particularly suited for a semantic conception of theories. Even though the construction of scientific phenomena is the main topic of this paper, the view presented here is more adapted to realism than social constructivism.     

Computation without Representation

The received view is that computational states are individuated at least in part by their semantic properties. I offer an alternative, according to which computational states are individuated by their functional properties. Functional properties are specified by a mechanistic explanation without appealing to any semantic properties. The primary purpose of this paper is to formulate the alternative view of computational individuation, point out that it supports a robust notion of computational explanation, and defend it on the grounds of how computational states are individuated within computability theory and computer science. A secondary purpose is to show that existing arguments for the semantic view are defective.     

ANTIVOLUNTARISM AND THE BIRTH OF AUTONOMY

Traditionalist and radical orthodox critiques of the Enlightenment assert that the modern discourse on moral self‐government constitutes a radical break with the theocentric model of morality which preceded it. Against this view, this paper argues that the conceptions of autonomy emerged from the effort to reconcile commitments within the Christian tradition. Through an analysis of the moral thought of the Cambridge Platonist Ralph Cudworth, this paper contends that distinctively Christian theological concerns concerning moral accountability to God and the character of divine‐human moral relationships produced a theory of moral autonomy which anticipates that of Kant. This paper highlights the role of anti‐voluntarism in the creation of this moral standpoint, and argues that the resultant moral view is an “internalization” of the voluntarist model of sovereignty.     

Thomas Reid on active power and free agency

The paper argues that it is a mistake to interpret Thomas Reid as holding a libertarian notion of freedom, and to make use of Reid to argue in support of a libertarian position. More precisely, this paper shows that Reid’s theory of agent-causation may not be what these philosophers take it to be, once such crucial notions as agent-causation and active power in Reid’s theory of free agency have been fully explicated. Reid is more committed to accepting the view of freedom as rational self-control over the determination of the will than a contracausal view of freedom.     

THE RISE,FALL, AND RESURRECTION OF (IDEOLOGICAL) SCIENTISM

The term “scientism” is often used as a denunciation of an uncritical ideological confidence in the abilities of science. Contrary to this practice, this article argues that there are feasible ways of defending scientism as a set of ideologies for political reform. Rejecting an essentialist approach to scientism as well as the view that ideologies have a solely negative effect on history, it argues that the political effect of ideologies inspired by a belief system (including scientism and various religions) must be judged case by case—and that the appearance of complex politico‐scientific problems such as the climate problem in effect warrants some kind of ideological scientism.     

Two approaches to natural kinds

Philosophical treatments of natural kinds are embedded in two distinct projects. I call these the philosophy of science approach and the philosophy of language approach. Each is characterized by its own set of philosophical questions, concerns, and assumptions. The kinds studied in the philosophy of science approach are projectible categories that can ground inductive inferences and scientific explanation. The kinds studied in the philosophy of language approach are the referential objects of a special linguistic category—natural kind terms—thought to refer directly. Philosophers may hope for a unified account addresses both sets of concerns. This paper argues that this cannot be done successfully. No single account can satisfy both the semantic objectives of the philosophy of language approach and the explanatory projects of the philosophy of science approach. After analyzing where the tensions arise, I make recommendations about assumptions and projects that are best abandoned, those that should be retained, and those that should go their separate ways. I also recommend adopting the disambiguating terminology of “scientific kinds” and “natural kinds” for the different notions of kinds developed in these different approaches.

     

Realism Detranscendentalized

John McDowell claims to find in Wittgenstein an approach to semantic notions which occupies a middle ground between antirealism and extreme forms of realism. The article sketches a proposal as to how to construe McDowell's Wittgensteinian position. The proposal exploits McDowell's suggestion that the position could be characterised as a combination of empirical realism and transcendental idealism concerning the status of semantic facts. The article argues that this combination is made possible by the fact that, when we attempt to characterise our own linguistic practices, the practice that we are trying to characterise is the very same practice that is supposed to yield the characterisation. One consequence of this is that commitment to antirealist principles requires embracing realism at the empirical level. Nevertheless, the contrast between this position and extreme realism remains problematic. The article ends by considering two proposals as to how this contrast could be rendered intelligble.     

Informal Proofs and Mathematical Rigour

The aim of this paper is to provide epistemic reasons for investigating the notions of informal rigour and informal provability. I argue that the standard view of mathematical proof and rigour yields an implausible account of mathematical knowledge, and falls short of explaining the success of mathematical practice. I conclude that careful consideration of mathematical practice urges us to pursue a theory of informal provability.     

Transcending Technology: Looking at Futurology as a New Religious Movement

This article argues that futurology is a new religious movement. Futurologists propose that the changes taking place in technology will radically alter human nature in the near future. The movement has its share of charismatic leaders, authoritative texts, and notions of salvation. I do not attempt to refute the vision of the future put forth by the futurologists themselves, but assume that their view of the future will unfold as they see it. This allows me more easily to gauge futurology's future relationship with religion. Rational choice theory is employed as a tool to discern whether futurology has the potential to be competitive when it enters the market-place of religions. I argue that, if the science behind it is perfected, futurology poses a real challenge to traditional religion.     

Getting Expression‐Based Semantics Right: Its Proper Objects of Evaluation and Limits

Often those attempting to resolve the answering machine paradox appeal to Kaplan's claim that the objects of semantic evaluation are expression‐types evaluated with respect to indices, instead of utterances, as part of their solution. This article argues that Dylan Dodd and Paula Sweeney exemplify the kind of mistakes theorists make in applying such expression‐based semantic theories in that (1) they conflate what is asserted with semantic content, and (2) they take their approach to utterance interpretation as having semantic significance. In light of these mistakes, we learn two things. First, we learn how expression‐based semantic theorists can avoid making these kinds of mistakes. Second, we learn how the limits of expression‐based semantics can contribute to what we should expect a semantic theory to explain regarding how semantics fits into a more general theory of linguistic communication and linguistic understanding.     

Some complexities in the relationship of psychoanalytic theory to technique

This paper considers the current fragmentation of psychoanalytic theory as a result of the illusorily close association of practice and theory. The author argues that the politically motivated assertion of a direct connection between theory and practice should be set aside and that practice should be liberated from theory, permitting theory to evolve in the context of radically modified patterns of practice. If theory were decoupled from practice, technique might progress on purely pragmatic grounds, on the basis of what is seen to work. Psychoanalytic theory of mental function could then follow practice, integrating what is newly discovered through innovative methods of clinical work. Such a pragmatic, principally action-oriented use of theory would bring psychoanalysis more in line with modern, postempirical views of science.     

Vikingism as a Metametaphysical Thesis

This paper aims to be a contribution to the recent discussion on the science‐metaphysics relationship. After drawing a distinction between two aspects of the relationship, it defends the theoretical importance of the proposed distinction and argues for the interconnectedness of the aspects in question. The paper then focuses on one of those aspects: that is, the methodological strategy of some metaphysicians to appeal to scientific findings and practice in the course of discussing various pure metaphysical problems. It discusses the question about the scope of science‐informed metaphysics and its relation to the issue concerning the existence of an autonomous metaphysical possibility. Finally, the paper explores the reasons metaphysicians have for involving science in metaphysical discussions.     

Modelling Beyond Application: Epistemic and Non-epistemic Values in Modern Science

In recent years, philosophers of science have begun to realize that the clear separation of the creation of models in academia and the application of models outside science is not possible. When these philosophers address hybrid contexts in which science is entwined with policy, business, and other realms of society, these often practically oriented realms no longer represent ‘the surroundings’ of science but rather are considered an essential part of it. I argue—and demonstrate empirically—that the judgement of a theory or model conducted by scientists in such hybrid contexts may contain two parts: one is truth supportive and the other is utility oriented. In relation to the debate on science and values, the article seeks to reinforce the argument in modern philosophy of science that the boundaries between epistemic and non-epistemic values are blurred. The article stresses that non-epistemic values may be also understood as values that contribute to the instrumental success of a theory or model and—in this way—influence scientific practice in the hybrid contexts.     

Enhancing Quality of Practice Through Theory of Change‐Based Evaluation: Science or Practice?

This paper describes the evaluation component of Partnerships for Success (PfS), a comprehensive community effort designed to address youth development issues. The evaluation component is referred to as theory of change-based evaluation. The author considers the implications of applying community practice tools such as theory of change-based evaluation to the current conceptualization of community science. More specifically, the author argues that the current conceptualization of community science pays scant attention to community practice. This paper concludes by suggesting that the current conceptualization of community science be modified to recognize the importance of community practice as an equal aspiration for community psychologists.     

Normativity in the Philosophy of Science

This paper analyzes what it means for philosophy of science to be normative. It argues that normativity is a multifaceted phenomenon rather than a general feature that a philosophical theory either has or lacks. It analyzes the normativity of philosophy of science by articulating three ways in which a philosophical theory can be normative. Methodological normativity arises from normative assumptions that philosophers make when they select, interpret, evaluate, and mutually adjust relevant empirical information, on which they base their philosophical theories. Object normativity emerges from the fact that the object of philosophical theorizing can itself be normative, such as when philosophers discuss epistemic norms in science. Metanormativity arises from the kind of claims that a philosophical theory contains, such as normative claims about science as it should be. Distinguishing these three kinds of normativity gives rise to a nuanced and illuminating view of how philosophy of science can be normative.     

The role of supervenience and constitution in neuroscientific research

This paper is concerned with the notions of supervenience and mechanistic constitution as they have been discussed in the philosophy of neuroscience. Since both notions essentially involve specific dependence and determination relations among properties and sets of properties, the question arises whether the notions are systematically connected and how they connect to science. In a first step, some definitions of supervenience and mechanistic constitution are presented and tested for logical independence. Afterwards, certain assumptions fundamental to neuroscientific inquiry are made explicit in order to show that the presented definitions of supervenience are virtually uninteresting for theory construction in this field. In a third step, a new formulation of supervenience is developed that makes explicit reference to the notion of constitution and that bridges the gap between the philosophical concepts and explanatory practice in neuroscience.     

Apologia pro Vita‐Fabula Sua: Defending Narrativity and How We Make Sense of Our Lives

This paper attempts to provide a defence for a narrative theory of the self in the face of criticisms from the anti‐narrative camp. It begins by addressing certain uncontroversial premises that both pro‐ and the anti‐narrative camps might be thought to agree on: the status of humans as homo significans or meaning‐makers, the natural form‐finding tendency and certain desiderata for significance and value that we possess, and the raw material of life and its constituents that we proceed from. Whereas the pro‐narrative camp seeks to provide the narrative theory of the self as a valid argument for how we proceed from the raw material of life and undifferentiated experience and these desiderata and tendencies (i.e.: the premises) to a conception of both selfhood and moral responsibility (i.e.: the conclusion), the anti‐narrative camp holds the conclusion to be false and the narrative theory of the self to be invalid. The Parfitian view holds the conception of the self to be ultimately false, whereas the Strawsonian view holds both the conception of the self and the conception of moral responsibility to be ultimately false. The grounds they provide, however, tend to be metaphysical in nature, demonstrating that they have fundamentally misunderstood how the narrative theory of the self functions as a semantic thesis. I will demonstrate certain defects in the metaphysical arguments that anti‐narrativists like Parfit and Strawson have made against what is essentially a semantic thesis about how we make sense of our lives. I will also attempt to shore up the semantic thesis in other relevant aspects.
