Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:REVIEW SYMPOSIUM 319 secular communities before making up their minds. But, in this case at least, minding theological business requires minding philosophical business. I wish all teachers of the Catholic community would study this book. JAMES J. BUCKLEY Loyola Oollege, Baltimore, Maryland RELIGIOUS DIVERSITY WILLIAM CHRISTIAN'S important new book appears at an opportune moment. It breaks new theoretical ground in the cross-cultural study of religious communities and religious (...) doctrines at a time when this is badly needed. Its contributions could be especially valuable for the burgeoning industry that produces books by Christian theologians on non-Christian religions, since there are signs that this industry is beginning to feed upon itself. Such books (and every year more are published) refer more and more to one another, to previous ' achievements ' in the field, and less and less to the purported object of their study: non-Christian religions themselves. So, in every new addition to the field we find the more-or-less obligatory discussions of Karl Barth's and Hendrik Kraemer's word-centered exclusivism; of Karl Rahner's hierarchical inclusivism; of Wilfred Cantwell Smith's faith-based ·experiential expressivism; and of John Hick's radical theocentric pluralism. There is usually comparatively little discussion of what any non-Christian tradition actually asserts, values, and practices. That is to say, Christian theologians, whose major specialty is theologizing about non-Christian religions, have entered the ·realms of secondary, or even tertiary, processing; they have made the enterprise of theologizing about these religions a purely abstract a priori intra-Christian enterprise, constrained not by the religions themselves, as they impinge upon and make claims upon members of the Christian community, but rather by presuppositions drawn only from some particular reading of the Christian tradition. So Rahner could deduce his theory of " anonymous REVIEW SYMPOSIUM Christians" from a few simple propositions (most importantly, the absoluteness of Christianity and the possibility of the presence of supernatural grace in non-Christian religions), without reference to the actual teachings, practices and values of any non-Christian tradition. The same is largely true for Hick's advocacy of a Copernican revolution in theological thought, and for Barth's rejection of all religion as unbelief. All are a priori positions. William Christian (both in his earlier Oppositions of Religious Doctrines [New York, 1972] and in the new Doctrines of Religious Communities) is one of the few philosophers of religion whose work on the nature of religious doctrines has a direct relevance for Christian thinking about non-Christian religions. It is, moreover, a relevance which, if taken seriously, could provide an agenda for that enterprise which would lift it out of the self-reflexive and largely unproductive agonizing in which it is currently mired. Given that Christian theologizing about non-Christian ;religions is something that neither can nor should be avoided, any work that opens up new avenues is to be welcomed. Christian's Doctrines is thus a potentially important book, and it is the object of this short piece to suggest in what its importance lies and how it is relevant to the Christian enterprise of theologizing about non-Christian religions. First, though, a caveat is in order: Christian's earlier work, with which his new book is directly continuous, has not, to this writer's perception, received the attention it deserves from theologians concerned with these matters. In that earlier work Christian was concerned to lay bare and analyze the logical conditions that must be met before it can properly be said that that two doctrine-expressing sentences contradict or oppose one another, and also to discuss the varieties of opposition that might occur. Oppositions of Religious Doctrines, the work in which he did this, is a book written by a philosopher in a philosophical idiom: it exhibits to a high degree the virtues of conceptual rigor and careful, precise analysis of terms and concepts. Largely for this reason, the work was not attractive to theologians. They are not trained to think in this idiom, and are not easily drawn to works written in it. The work also received comparatively little attention from analyticallytrained philosophers of religion, those who should, by training and taste, find its idiom comfortable... (shrink)

This essay considers what it means to understand natural language and whether a computer running an artificial-intelligence program designed to understand natural language does in fact do so. It is argued that a certain kind of semantics is needed to understand natural language, that this kind of semantics is mere symbol manipulation (i.e., syntax), and that, hence, it is available to AI systems. Recent arguments by Searle and Dretske to the effect that computers cannot understand natural language are discussed, and (...) a prototype natural-language-understanding system is presented as an illustration.

John Searle once said: "The Chinese room shows what we knew all along: syntax by itself is not sufficient for semantics. (Does anyone actually deny this point, I mean straight out? Is anyone actually willing to say, straight out, that they think that syntax, in the sense of formal symbols, is really the same as semantic content, in the sense of meanings, thought contents, understanding, etc.?)." I say: "Yes". Stuart C. Shapiro has said: "Does that make any sense? Yes: Everything (...) makes sense. The question is: What sense does it make?" This essay explores what sense it makes to say that syntax by itself is sufficient for semantics. (shrink)

This essay continues my investigation of `syntactic semantics': the theory that, pace Searle's Chinese-Room Argument, syntax does suffice for semantics (in particular, for the semantics needed for a computational cognitive theory of natural-language understanding). Here, I argue that syntactic semantics (which is internal and first-person) is what has been called a conceptual-role semantics: The meaning of any expression is the role that it plays in the complete system of expressions. Such a `narrow', conceptual-role semantics is the appropriate sort of semantics (...) to account (from an `internal', or first-person perspective) for how a cognitive agent understands language. Some have argued for the primacy of external, or `wide', semantics, while others have argued for a two-factor analysis. But, although two factors can be specified–-one internal and first-person, the other only specifiable in an external, third-person way–-only the internal, first-person one is needed for understanding how someone understands. A truth-conditional semantics can still be provided, but only from a third-person perspective. (shrink)

I advocate a theory of syntactic semantics as a way of understanding how computers can think (and how the Chinese-Room-Argument objection to the Turing Test can be overcome): (1) Semantics, considered as the study of relations between symbols and meanings, can be turned into syntax – a study of relations among symbols (including meanings) – and hence syntax (i.e., symbol manipulation) can suffice for the semantical enterprise (contra Searle). (2) Semantics, considered as the process of understanding one domain (by modeling (...) it) in terms of another, can be viewed recursively: The base case of semantic understanding –understanding a domain in terms of itself – is syntactic understanding. (3) An internal (or narrow ), first-person point of view makes an external (or wide ), third-person point of view otiose for purposes of understanding cognition. (shrink)

The proper treatment of computationalism, as the thesis that cognition is computable, is presented and defended. Some arguments of James H. Fetzer against computationalism are examined and found wanting, and his positive theory of minds as semiotic systems is shown to be consistent with computationalism. An objection is raised to an argument of Selmer Bringsjord against one strand of computationalism, namely, that Turing-Test± passing artifacts are persons, it is argued that, whether or not this objection holds, such artifacts will inevitably (...) be persons.

Syntactic semantics is a holistic, conceptual-role-semantic theory of how computers can think. But Fodor and Lepore have mounted a sustained attack on holistic semantic theories. However, their major problem with holism (that, if holism is true, then no two people can understand each other) can be fixed by means of negotiating meanings. Syntactic semantics and Fodor and Lepore’s objections to holism are outlined; the nature of communication, miscommunication, and negotiation is discussed; Bruner’s ideas about the negotiation of meaning are explored; (...) and some observations on a problem for knowledge representation in AI raised by Winston are presented.

There are many branches of philosophy called “the philosophy of X,” where X = disciplines ranging from history to physics. The philosophy of artificial intelligence has a long history, and there are many courses and texts with that title. Surprisingly, the philosophy of computer science is not nearly as well-developed. This article proposes topics that might constitute the philosophy of computer science and describes a course covering those topics, along with suggested readings and assignments.

This essay re-examines Meinong's "Über Gegenstandstheorie" and undertakes a clarification and revision of it that is faithful to Meinong, overcomes the various objections to his theory, and is capable of offering solutions to various problems in philosophy of mind and philosophy of language. I then turn to a discussion of a historically and technically interesting Russell-style paradox (now known as "Clark's Paradox") that arises in the modified theory. I also examine the alternative Meinong-inspired theories of Hector-Neri Castañeda and Terence Parsons.

A fundamental assumption of Alexius Meinong's 1904 Theory of Objects is the act-content-object analysis of psychological experiences. I suggest that Meinong's theory need not be based on this analysis, but that an adverbial theory might suffice. I then defend the adverbial alternative against an objection raised by Roderick Chisholm, and conclude by presenting an apparently more serious objection based on a paradox discovered by Romane Clark.

This essay examines the role of non-existent objects in "epistemological ontology" — the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Außersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

Critical Review of Searle's Minds, Brains and Science.

A critical study of John Searle's Minds, Brains and Science (Cambridge, MA: Harvard University Press, 1984).

Hauser argues that his pocket calculator (Cal) has certain arithmetical abilities: it seems Cal calculates. That calculating is thinking seems equally untendentious. Yet these two claims together provide premises for a seemingly valid syllogism whose conclusion - Cal thinks - most would deny. He considers several ways to avoid this conclusion, and finds them mostly wanting. Either we ourselves can't be said to think or calculate if our calculation-like performances are judged by the standards proposed to rule out Cal; or (...) the standards- e.g., autonomy and self-consciousness- make it impossible to verify whether anything or anyone (save oneself) meets them. While appeals to the intentionality of thought or the unity of minds provide more credible lines of resistance, available accounts of intentionality and mental unity are insufficiently clear and warranted to provide very substantial arguments against Cal's title to be called a thinking thing. Indeed, considerations favoring granting that title are more formidable than is generally appreciated. Rapaport's comments suggest that, on a strong view of thinking, mere calculating is not thinking (and pocket calculators don't think), but on a weak, but unexciting, sense of thinking, pocket calculators do think. He closes with some observations on the implications of this conclusion. (shrink)

The evolutionist challenge to moral realism is the skeptical challenge that, if evolution is true, it would only be by chance, a “happy coincidence” as Sharon Street puts it, if human moral beliefs were true. The author formulates Street’s “happy coincidence” argument more precisely using a distinction between probabilistic sensitivity and insensitivity introduced by Elliott Sober. The author then considers whether it could be rational for us to believe that human moral judgments about particular cases are probabilistically sensitive to strongly (...) universal fundamental moral standards of cooperation and fair division. The author provides an explanation of why there would be a benign correlation between human moral judgments in particular cases and the requirements of strongly universal fundamental moral standards. The explanation of the benign correlation is based on group selection for groups of individuals with an egalitarian satisficing psychology and egalitarian norms, because of the ability of such groups to more efficiently solve gene-propagation collective action problems.

This essay describes computational semantic networks for a philosophical audience and surveys several approaches to semantic-network semantics. In particular, propositional semantic networks are discussed; it is argued that only a fully intensional, Meinongian semantics is appropriate for them; and several Meinongian systems are presented.

Alexius Meinong developed a notion of defective objects in order to account for various logical and psychological paradoxes. The notion is of historical interest, since it presages recent work on the logical paradoxes by Herzberger and Kripke. But it fails to do the job it was designed for. However, a technique implicit in Meinong's investigation is more successful and can be adapted to resolve a similar paradox discovered by Romane Clark in a revised version of Meinong's Theory of Objects due (...) to Rapaport. One family of paradoxes remains, but it is argued that they are unavoidable and relatively harmless. (shrink)

Part I argues that ontological arguments, like other classical proofs of the existence of God, are parts of larger arguments in which they are embedded. These larger arguments include reasons supporting the proofs’ premises and responses to them, and to the proofs’ claims to validity and non-circularity, since, in the final analysis, our assessment of the proofs will express our best judgment of the cumulative force of all the considerations bearing on their overall adequacy. Part II illustrates these points by (...) examining contemporary defences of, and attacks on, one of the ontological argument’s central premises, namely, that God’s existence is logically possible.

The author uses a series of examples to illustrate two versions of a new, nonprobabilist principle of epistemic rationality, the special and general versions of the metacognitive, expected relative frequency principle. These are used to explain the rationality of revisions to an agent’s degrees of confidence in propositions based on evidence of the reliability or unreliability of the cognitive processes responsible for them—especially reductions in confidence assignments to propositions antecedently regarded as certain—including certainty-reductions to instances of the law of excluded (...) middle or the law of noncontradiction in logic or certainty-reductions to the certainties of probabilist epistemology. The author proposes special and general versions of the MERF principle and uses them to explain the examples, including the reasoning that would lead to thoroughgoing fallibilism—that is, to a state of being certain of nothing. The author responds to the main defenses of probabilism: Dutch Book arguments, Joyce’s potential accuracy defense, and the potential calibration defenses of Shimony and van Fraassen by showing that, even though they do not satisfy the probability axioms, degrees of belief that satisfy the MERF principle minimize expected inaccuracy in Joyce’s sense; they can be externally calibrated in Shimony and van Fraassen’s sense; and they can serve as a basis for rational betting, unlike probabilist degrees of belief, which, in many cases, human beings have no rational way of ascertaining. The author also uses the MERF principle to subsume the various epistemic akrasia principles in the literature. Finally, the author responds to Titelbaum’s argument that epistemic akrasia principles require that we be certain of some epistemological beliefs, if we are rational. (shrink)

I argue that George Nakhnikian's analysis of the logic of cogito propositions (roughly, Descartes's 'cogito' and 'sum') is incomplete. The incompleteness is rectified by showing that disjunctions of cogito propositions with contingent, non-cogito propositions satisfy conditions of incorrigibility, self-certifyingness, and pragmatic consistency; hence, they belong to the class of propositions with whose help a complete characterization of cogito propositions is made possible.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 719 An Apology for Apologetics: A Study in the Logic of lnterreligious Dialogue. By PAUL J. GRIFFITHS. New York: Orbis, 1991. ISBN: 0 88344 761 4. pp. 113. Jesus Christ at the Encounter of World Religions. By J. DUPUIS. New York: Orbis, 1991 (ET: Robert R. Barr, from French, 1989). ISBN: 0 88344 723 1. pp. 301. Griffiths presents a rigorous argument for the possibility of con· (...) tradictory claims between different religious communities. His inspira· tion, as he acknowledges, is William Christian Snr. His basic argu· ment is: " If representative intellectuals belonging to some specific religious community come to judge at a particular time that some or all of their own doctrine-expressing sentences are incompatible with some alien religious claim(s), then they should feel obliged to engage in both positive and negative apologetics vis-a-vis these alien religious claim(s) and their promulgators" (3). He takes negative apologetics to be a critique of arguments made against one's own religious claims, showing that such arguments fail or are inconsistent or incoherent. Positive apologetics shows how a particular religious community's doctrines are cognitively superior, in some respect(s), to another religious community 's doctrines. It is essential for this enterprise that only methods of argumentation and criteria of knowledge acceptable to the adversary are employed. This requires the acceptance of natural theology. Griffiths is well aware of the lion's den he is entering, as his proposals run counter to much scholarship in the area of interreligious dialogue, so he spends three chapters apologetically tackling the lions. The objectors (who mainly remain in notes) include Derrida, Barthes, Winch, Lindbeck, Hick, Huxley, Nasr, Plantinga and others, although Mac· Intyre is curiously missing. This technique has the advantage of isolating and presenting arguments, without falling into problems of cor· rect exegesis of opponents. And this is also its weakness, as objectors will sometimes feel caricatured or misunderstood-as is surely the case with Plantinga and in one instance, Hick. First, he tackles objections that sentences from one tradition are either incomprehensible or incommensurable with those of another, convincingly showing that the strong versions of both claims are self· defeating and unsustainable. Weaker versions still allow for his proj· ect-or so he thinks. This is where Maclntyre's work should have been considered. Then he tackles various theories of religious language (following Lindbeck's typology). He argues against non-cognitive accounts that reduce beliefs to the credibility of causes for holding beliefs, a position incapable of asserting its truth over other views because of its 720 BOOK REVIEWS own presuppositions. He follows Lindbeck in criticizing experiental expressivism, and then turns upon Lindbeck's own form of rule theory (which is ambivalent regarding cognitive claims), arguing convincingly that to suggest that only sentences uttered confessionally and with performative function can possess ontological truth is confused (42). In a brief review it is not possible to rehearse Griffiths's careful argumentation. Griffiths then sets about tackling two types of universalists: Hick and Huxley. Of Hick, he argues that some criteria are required to discern true from false religions (e.g. Jim Jones) and in so doing such a position needs to support and develop such criteria, thereby effectively introducing apologetics. He neglects to deal with Hick's pragmatic criteria of beneficial ' fruits ' evident in adherents, but the logic of his argument can be applied to Hick's proposals. Using Katz and Zaehner, he argues against the esoteric universalism of the philosophia perennis. (The arguments of Robert Forman's recent book, The Problems of Pure Consciousness, are strangely neglected, despite Griffiths's being a contributor to that collection.) Finally, he tackles objections against positive apologetics-first, on the grounds that it has a negative effect on interreligious relations. Logically, this need not be the case, although Griffiths is well aware that the political context of apologetics can obscure its proper goal: deeper critical understanding, learning and problem solving. Then, in sustained dialogue with Plantinga, he argues against the objection that success is impossible. It is impossible only if " knockdown drag-out" (64) argumentative victory is expected. Griffiths suggests the cumulative -case argument and gives instances of such successful apologetics (medieval... (shrink)

Between the opposing claims of reason and religious subjectivity may be a middle ground, William J. Wainwright argues. His book is a philosophical reflection on the role of emotion in guiding reason. There is evidence, he contends, that reason functions properly only when informed by a rightly disposed heart. The idea of passional reason, so rarely discussed today, once dominated religious reflection, and Wainwright pursues it through the writings of three of its past proponents: Jonathan Edwards, John Henry Newman, (...) and William James. He focuses on Edwards, whose work typifies the Christian perspective on religious reasoning and the heart. Then, in his discussion of Newman and James, Wainwright shows how the emotions participate in non-religious reasoning. Finally he takes up the challenges most often posed to notions of passional reason: that such views justify irrationality and wishful thinking, that they can't be defended without circularity, and that they lead to relativism. His response to these charges culminates in an eloquent and persuasive defense of the claim that reason functions best when influenced by the appropriate emotions, feelings, and intuitions. (shrink)

This article presents findings from a series of research studies designed to identify classroom teaching practices that can enhance moral reasoning of undergraduate students in business foundational courses. The research, conducted over five semesters at a Midwestern university, resulted in the development of teaching methods and materials that can, when properly sequenced and integrated into undergraduate business courses, increase levels of student moral reasoning as measured by the revised version of the Defining Issues Test (DIT-2). Findings in this research demonstrate (...) that faculty members who are not specialists in business ethics can effect positive increases in student moral reasoning in non-ethics business courses. However, significant time and effort must be invested in case-based moral decision making, and grade incentives for students to engage the use of an ethical decision-making framework are required.

In this comment I discuss the role of an ethics case consultant in an institutional setting, in contrast to situations when an ethics consultant serves an individual client. In the former situation, I believe the case consultant should articulate ethical issues, options, and arguments, but not recommend a particular course of conduct. In the latter situation, the role of the ethics consultant can be defined and determined in negotiations with the client.

I argue that, when Alcibiades' encomium to Socrates is interpreted in light of Socrates' presentation of Diotima's speech, which immediately proceeds it, it shows Socrates to be at the top level of Diotima's "ladder of ascent" to Beauty. If Alcibiades is correct, Socrates' pretense of ignorance is an ironic sham. Socrates, as Plato's mystagogos, must have experiential knowledge of the Form of Beauty.

Originally published in 1990. Examining epistemic justification, truth and logic, this book works towards a holistic theory of knowledge. It discusses evidence, belief, reliability and many philosophical theories surrounding the nature of true knowledge. A thorough Preface updates the main work from when it was written in 1976 to include theories ascendant in the ‘80s.
