Accounts of what it is for an agent to be justified in holding a belief commonly carry commitments concerning what cognitive processes can and should be like. A concern for the plausibility of such commitments leads to a multi-faceted epistemology in which elements of traditionally conflicting epistemologies are vindicated within a single epistemological account. The accessible and articulable states that have been the exclusive focus of much epistemology must constitute only a proper subset of epistemologically relevant processing. The interaction of (...) such states looks rather contextualist. It might also be called quasi-foundationalist. However, in attending to our epistemological tasks we must rely on processing that is sensitive to information that we could not articulate, that is not accessible in the standard internalist sense. When focusing on the full range of epistemologically important processes, the structure of what makes for justification is rather more like that envisioned by some coherentists. (shrink)

This dissertation is a work in the philosophical foundations of cognitive modelling. To a significant extent, it is presented as a response to a critique of connectionist modelling originated by Jerry Fodor and Zenon Pylyshyn. The essence of the critique is that either connectionist models implement classical models of cognition, or if connectionist models are not implementational, then they are incapable of modelling cognition. I argue that barring an implausible interpretation of "implementation," there exists a subset of connectionist models which (...) cannot be implementations of classical models, and while no connectionist researcher has met all the demands Fodor and Pylyshyn placed on adequate models of cognition, the properties possessed by some non-implementational connectionist models provide reason to think that these demands can be met in principle, and that connectionist models are capable of kinds of processing which classical models are not capable of, processing which makes connectionist models worth developing in spite of some of their present limitations. ;Many have responded to the Fodor and Pylyshyn critique. However, the responses have not payed sufficient attention to key notions such as implementation and rule. One of the principal contributions of this dissertation will be an analysis of the notion of implementation. The notion of a tacit rule also will be defined. Many have suggested that the difference between connectionist and classical models of cognition is that connectionist nets do not have explicit rules. I argue that the preceding is incorrect; I also argue that there is a certain kind of rule which connectionist nets cannot be understood as implementing--a tacit rule. ;Chapters one through four respond to the Fodor and Pylyshyn argument against connectionism. Chapter five takes up a critique of connectionist models made by Andy Clark. Chapter six responds to an argument by Terrence Horgan and John Tienson which aims to show that folk psychological laws make use of a type of ceteris paribus clause not possessed by physical laws. Horgan and Tienson are shown not to have made a persuasive case. (shrink)

I defend the view that supervenience relations need not be explained. My view is that some supervenience relations are brute, and explanatorily ultimate. I examine an argument of Terrence Horgan and Mark Timmons. They aim to rehabilitate John Mackie’s metaphysical queerness argument. But the explanations of supervenience that Horgan and Timmons demand are semantic explanations. I criticize their attempt to explain psychophysical supervenience in this fashion. I then turn to their ‘Twin Earth’ argument against naturalist moral realism. (...) I reconstruct their argument in a charitable spirit. But then I show that the argument mutates into an epistemological argument. That is where the real problems for moral realism lie. (shrink)

In recent years, with the appearance of a new wave of realism and non-descriptivism, the old dispute in meta-ethics between cognitivism and non-cognitivism has resurfaced. At present one of the most intensely discussed arguments among meta-ethicists is the so-called Moral Twin Earth argument of Terrence Horgan and Mark Timmons. It was presented in a series of articles published at the beginning of the nineties. However, a similar argument was put forth much earlier by Richard Hare, though the participants (...) of the discussion that has arisen in connection with the Moral Twin Earth have passed over it in silence. It appeared for the first time at the beginning of the fifties in The Language of Morals as the Missionary and the Cannibal Islands argument. Hare later renamed it the Reductio ad Absurdum of Descriptivism in an article published in 1986 under the same name. Since then he has made it as his basic instrument against descriptivism. In the present article the author outlines the argument of Moral Twin Earth, presents its prototype, and offers a concise criticism of it. (shrink)

The superassertability theory of truth, inspired by Crispin Wright (1992, 2003), holds that a statement is true if and only if it is superassertable in the following sense: it possesses warrant that cannot be defeated by any improvement of our information. While initially promising, the superassertability theory of truth is vulnerable to a persistent difficulty highlighted by James Van Cleve (1996) and Terrence Horgan (1995) but not properly fleshed out: it is formally illegitimate in a similar sense that (...) unsophisticated epistemic theories of truth are widely acknowledged to be. Sustained analysis reveals that the unrestricted formal legitimacy argument is firmly grounded in first person conceivability evidence. (shrink)

To explore how molecules became signs I will ask: “What sort of process is necessary and sufficient to treat a molecule as a sign?” This requires focusing on the interpreting system and its interpretive competence. To avoid assuming any properties that need to be explained I develop what I consider to be a simplest possible molecular model system which only assumes known physics and chemistry but nevertheless exemplifies the interpretive properties of interest. Three progressively more complex variants of this model (...) of interpretive competence are developed that roughly parallel an icon-index-symbol hierarchic scaffolding logic. The implication of this analysis is a reversal of the current dogma of molecular and evolutionary biology which treats molecules like DNA and RNA as the original sources of biological information. Instead I argue that the structural characteristics of these molecules have provided semiotic affordances that the interpretive dynamics of viruses and cells have taken advantage of. These molecules are not the source of biological information but are instead semiotic artifacts onto which dynamical functional constraints have been progressively offloaded during the course of evolution.

A provocative ontological-cum-semantic position asserting that the right ontology is austere in its exclusion of numerous common-sense and scientific posits and that many statements employing such posits are nonetheless true. The authors of Austere Realism describe and defend a provocative ontological-cum-semantic position, asserting that the right ontology is minimal or austere, in that it excludes numerous common-sense posits, and that statements employing such posits are nonetheless true, when truth is understood to be semantic correctness under contextually operative semantic standards. Terence (...) Horgan and Matjaz Potrc argue that austere realism emerges naturally from consideration of the deep problems within the naive common-sense approach to truth and ontology. They offer an account of truth that confronts these deep internal problems and is independently plausible: contextual semantics, which asserts that truth is semantically correct affirmability. Under contextual semantics, much ordinary and scientific thought and discourse is true because its truth is indirect correspondence to the world. After offering further arguments for austere realism and addressing objections to it, Horgan and Potrc consider various alternative austere ontologies. They advance a specific version they call "blobjectivism"--the view that the right ontology includes only one concrete particular, the entire cosmos, which, although it has enormous local spatiotemporal variability, does not have any proper parts. The arguments in Austere Realism are powerfully made and concisely and lucidly set out. The authors' contentions and their methodological approach--products of a decade-long collaboration--will generate lively debate among scholars in metaphysics, ontology, and philosophy. (shrink)

Police killings of unarmed Black people have ignited a national and international response unlike any in decades. But differing from their civil rights-oriented predecessors, today’s activists do not think that the institutions and values of liberal democracy can eradicate structural racism. They draw instead on a Black radical tradition that, Terrence L. Johnson argues, derives its force from its unacknowledged ethical and religious dimensions. We Testify with Our Lives traces Black religion’s sustained influence from SNCC to the present, reconstructing (...) a radical lived ethics of freedom and justice. Johnson demonstrates that Black Power fundamentally contests liberalism’s abstract understanding of democracy, calling instead for new embodied frameworks to achieve human flourishing and dignity. Black bodies represent the primary form of resistance against violent and oppressive regimes of white supremacy and exploitation, and the individual and collective struggles of Black life bear witness to the dogged determination to cultivate beauty, rage, and joy. Considering the writings of Audre Lorde, Toni Cade Bambara, Stokely Carmichael, Martin Luther King Jr., Malcolm X, and James Baldwin, We Testify with Our Lives makes its case through a new narrative of the evolution of Black radicalism from the civil rights movement through the Movement for Black Lives. It forges new insights into Black Power’s vital contributions to debates on ethics, transnational politics, democracy, political solidarity, and freedom—and its potent resources for the ongoing struggle to build democratic possibilities for all.

There have been times in the history of ethical theory, especially in this century, when moral realism was down, but it was never out. The appeal of this doctrine for many moral philosophers is apparently so strong that there are always supporters in its corner who seek to resuscitate the view. The attraction is obvious: moral realism purports to provide a precious philosophical good, viz., objectivity and all that this involves, including right answers to (most) moral questions, and the possibility (...) of knowing those answers. In the last decade, moral realism has re-entered the philosophical ring in powerful-looking naturalistic form. ln this paper we provide a dialectical overview: we situate the new wave position itself, and also our objections to it, in the context of the evolving program of philosophical naturalism in 20th century analytic philosophy. We seek to show that although this new contender might initially look like championship material, it succumbs to punches surprisingly similar to those that knocked out the old-fashioned versions of naturalist moral realism.

Soon it may be possible to promote the rehabilitation of criminal offenders through _neurointerventions_ (interventions which exert direct physical, chemical or biological effects on the brain). Some jurisdictions already utilise neurointerventions to diminish the risk of sexual or drug-related reoffending. And investigation is underway into several other neurointerventions that might also have rehabilitative applications within criminal justice—for example, pharmacotherapy to reduce aggression or impulsivity. Ethical debate on the use of neurointerventions to facilitate rehabilitation—henceforth ‘neurorehabilitation’—has proceeded on two assumptions: that we (...) have instrumental reasons for employing neurorehabilitation (e.g. because it helps protect the public from crime); and that its permissibility depends upon whether its use unjustifiably infringes offenders’ rights. This paper defends a different, hitherto neglected thought. I argue we have rights-based reasons to offer neurorehabilitation to offenders—in other words, that offenders have a _moral right_ to neurorehabilitation. I identify three considerations which support a moral right to conventional rehabilitative interventions—(1) as a countermeasure to the debilitating side-effects of punishment; (2) as a derivative right of the right to hope for renewed liberty; and (3) as compensation for structural injustice. I argue these considerations extend to support a moral right to neurorehabilitation in the following instance: when neurorehabilitation would be part of the _most effective_ package for facilitating rehabilitation, and can be carried out at reasonable cost. I then defend my argument against potential objections, including the objection that neurorehabilitation is a bad option for offenders to have and the charge of over-medicalisation. (shrink)

Christian hope of resurrection requires that the one raised be the same person who died. Philosophers and theologians alike seek to understand the coherence of bodily resurrection and what accounts for numerical identity between the earthly and risen person. I address this question from the perspective of disability. Is a person with a disability raised in the age to come with that disability? Many theologians argue that disability is essential to one's identity such that it could not be eliminated in (...) the resurrection. What anthropology undergirds these claims is not often explicated. I argue that Thomistic hylemorphic anthropology provides the best context to understand the human person such that disability is not essential to identity. In the resurrection, we shall become truly ourselves. The marks of disability may remain, but Thomistic anthropology expresses the coherence of bodily resurrection in which one may hope for healing which eliminates the disability but not numerical identity.

Causal compatibilism claims that even though physics is causally closed, and even though mental properties are multiply realizable and are not identical to physical causal properties, mental properties are causal properties nonetheless. This position asserts that there is genuine causation at multiple descriptive/ontological levels; physics-level causal claims are not really incompatible with mentalistic causal claims. I articulate and defend a version of causal compatibilism that incorporates three key contentions. First, causation crucially involves robust patterns of counterfactual dependence among properties.Second, often (...) several distinct such patterns, all subsuming a single phenomenon, exist at different descriptive/ontological levels (e.g., microphysical, neurobiological, macrobiological, and psychological). Third, the concept of causation is governed by an implicit contextual parameter that normally determines a specific descriptive/ontological level as the contextually relevant level, for the context-sensitive semantic evaluation of causal statements.

This paper addresses an alleged paradox regarding gratitude—that a duty of gratitude is odd or puzzling if not paradoxical. The gist of our position is that in prototypical cases, gratitude expression falls under a distinctive deontic category we call morally expected—which has a corresponding contrary deontic category we call morally offensive. These categories, we maintain, need recognition in normative ethics to make proper sense of the moral status of gratitude expression and other morally charged restrictions on action, and likewise to (...) make proper sense of the moral status of failures to abide by such restrictions. We argue for our view largely on phenomenological grounds. (shrink)

I explore the prospects for overcoming the prima facie tension in the following four claims, all of which I accept: the phenomenal character of experience is narrow; virtually all aspects of the phenomenal character of experience are intentional; the most fundamental kind of mental intentionality is fully constituted by phenomenal character; and yet introspection does not by itself reliably generate answers to certain philosophically important questions about the phenomenally constituted intentional content of experience. The apparent tension results from the following (...) initially plausible thought: if indeed the answers to such questions are entirely fixed by phenomenal character by itself, then presumably these answers should be directly available introspectively. I focus the discussion specifically on certain questions about the phenomenal intentional content of agentive experience—e.g., the question whether the content of agentive experience is compatible with causal determinism. I consider three alternative possibilities for explaining why the answers to such questions are not directly available introspectively—two of which I argue against and the third of which I embrace.

The paper describes the approach by which ethics are integrated into the undergraduate curriculum at Northern Illinois University''s College of Business. Literature is reviewed to identify conceptual frameworks for, and issues associated with, the teaching of business ethics. From the review, a set of guidelines for teaching ethics is developed and proposed. The objectives and strategies implemented for teaching ethics is discussed. Foundation and follow-up coursework, measurement issues and ancillary programs are also discussed.

By recourse to the fundamentals of preference orderings and their numerical representations through linear utility, we address certain questions raised in Nover and Hájek 2004, Hájek and Nover 2006, and Colyvan 2006. In brief, the Pasadena and Altadena games are well-defined and can be assigned any finite utility values while remaining consistent with preferences between those games having well-defined finite expected value. This is also true for the St Petersburg game. Furthermore, the dominance claimed for the Altadena game over the (...) Pasadena game, and that would have been claimed for the St Petersburg game over the Altadena, can be contradicted without fear of inconsistency with the axioms of utility theory. However, insistence upon dominance can be made to yield a contradiction of the Archimedean axiom of utility theory. CiteULike Connotea Del.icio.us What's this? (shrink)

Cognitive theories have expressed their components using an artificial symbolic language, such as first-order predicate logic, and the atoms in such representations are non-decomposable letter strings. A neural theory merely demonstrates how to implement a classical symbol system using neurons: this is actually an argument against the importance of the neural description. The fact that symbol systems are physically instantiated in neurons becomes a mere implementational detail, since there is a direct way to translate from the symbolic description to the (...) more neurally plausible one. It might then be argued that, while the neural aspects of the theory identify how behavior arises, they are not fundamentally important for understanding that behavior. Classical symbol systems would continue to be seen as the right kinds of description for psychological processes. (shrink)

Contemporary cognitive science has two principal branches: the classical computational approach (sometimes called classicism) and connectionism. Rules are fundamental to theorizing about the basic units of processing in both classicism and connectionism. But we will be concerned primarily with rules that apply to representations and that determine transitions from one cognitive/representational state to the next. Such rules are fundamental to classicism, since, according to classicism, cognitive processes simply are rule‐governed cognitive state transitions. Rules that apply to representations are not a (...) built‐in feature of connectionist architecture, so the role of such rules in connectionism is less clear. We will argue that they are neither necessary nor (in general) desirable in connectionism. We discuss the status of rules first in classicism, then in connectionism. (shrink)

In his 2013 Theoria article, “Unreliable Intuitions: A New Reply to the Moral Twin-Earth Argument,” Jorn Sonderholm attempts to undermine our moral twin earth argument against Richard Boyd's moral semantics by debunking the semantic intuitions that are prompted by reflection on the thought experiment featured in the MTE argument. We divide our reply into three main sections. In section 1, we briefly review Boyd's moral semantics and our MTE argument against this view. In section 2, we set forth what we (...) take to be Sonderholm's master debunking argument, along with his proposed Boydian explanation of the semantic intuitions he seeks to debunk. Then in section 3, we mount our defence of the semantic intuitions under scrutiny, arguing on abductive grounds that, contrary to Sonderholm, the semantic intuitions generated by reflection on MTE scenarios are to be trusted in evaluating the plausibility of Boydian moral semantics. Section 4 is our summary and conclusion. (shrink)

I distinguish two broad approaches to vagueness that I call "robust" and "wimpy". Wimpy construals explain vagueness as robust (i.e., does not manifest arbitrary precision); that standard approaches to vagueness, like supervaluationism or appeals to degrees of truth, wrongly treat vagueness as wimpy; that vagueness harbors an underlying logical incoherence; that vagueness in the world is therefore impossible; and that the kind of logical incoherence nascent in vague terms and concepts is benign rather than malignant. I describe some implications for (...) logic, semantics, and metaphysics. (shrink)
