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.

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)

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)

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

A critical survey of some attempts to define ‘computer’, beginning with some informal ones, then critically evaluating those of three philosophers, and concluding with an examination of whether the brain and the universe are computers.

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

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.

We give a short proof of a lemma which generalizes both the main lemma from the original construction in the author’s thesis of a model with no ω2-Aronszajn trees, and also the “Key Lemma” in Hamkins’ gap forcing theorems. The new lemma directly yields Hamkins’ newer lemma stating that certain forcing notions have the approximation property.

This paper argues that we ought to conceive of the Dark Energy problem—the question of how to account for observational data, naturally interpreted as accelerated expansion of the universe—as a crisis of underdetermined pursuit-worthiness. Not only are the various approaches to the Dark Energy problem evidentially underdetermined; at present, no compelling reasons single out any of them as more likely to be true than the other. More vexingly for working scientists, none of the approaches stands out as uncontroversially preferable over (...) its rivals in terms of its rationally warranted promise, i.e. the reasons to further work on, explore, and develop it. We demonstrate this claim by applying a Peircean economic model of pursuit-worthiness in terms of a cognitive cost/benefit estimate—with the instantiation of theory virtues as key indicators of cognitive gains—to the four main Dark Energy proposals (the cosmological constant approach, modified gravity, quintessence, and inhomogeneous cosmologies). According to our analysis, these approaches do not admit of an unambiguous, or uncontroversial, ranking with respect to which ansatz deserves distinguished attention and research efforts. The overall methodological counsel that our analysis underwrites recommends a pragmatic double research strategy forward: to encourage and foster theory pluralism and the search for tests—with the goal of enhancing the testability of the \(\Lambda \) CDM model and “testing it to destruction".

The author identifies the structure of Sharon Street's skeptical challenge to non-naturalist, normative epistemic realism as an argument that NNER is liable to reliability defeat and then argues that Street's argument fails, because it itself is subject to reliability defeat. As the author reconstructs Street's argument, it is an argument that the normative epistemic judgments of the realist could only be probabilistically sensitive to normative epistemic truths by sheer chance. The author then recaps Street's own naturalist translation of normative epistemic (...) judgments into purely descriptive, contingent probability statements, and argues that, on her own terms, the reasoning that leads her to rationally believe in evolutionary theory could only be probabilistically sensitive to the relevant purely descriptive, contingent probabilities by sheer chance. The author's argument is addressed to Street, but it applies to all evolutionary naturalist accounts of epistemic rationality. The author explains how his argument differs from Plantinga's Evolutionary Argument Against Naturalism and shows how it avoids the objections to Plantinga's EAAN. The author closes with the outline of an explanation of how evolution could have made human reasoning probabilistically sensitive to metaphysically necessary normative epistemic standards, even though those standards did not exert and, indeed, could not have exerted any kind of causal influence on the evolutionary process.

Ford’s Helen Keller Was Never in a Chinese Room claims that my argument in How Helen Keller Used Syntactic Semantics to Escape from a Chinese Room fails because Searle and I use the terms ‘syntax’ and ‘semantics’ differently, hence are at cross purposes. Ford has misunderstood me; this reply clarifies my theory.

This paper describes the SNePS knowledge-representation and reasoning system. SNePS is an intensional, propositional, semantic-network processing system used for research in AI. We look at how predication is represented in such a system when it is used for cognitive modeling and natural-language understanding and generation. In particular, we discuss issues in the representation of fictional entities and the representation of propositions from fiction, using SNePS. We briefly survey four philosophical ontological theories of fiction and sketch an epistemological theory of fiction (...) using a story operator and rules for allowing propositions to migrate into and out of story spaces.

This paper explores three questions: (1) Why should Certified Public Accountants (CPAs), as a group, adhere to their code of ethics? (2) Why should an individual CPA adhere to the code? (3) Of what significance are the answers to these questions in regards to possible changes in the accounting curriculum and the CPA profession's present concern for self-regulation through quality control reviews? The paper concludes that all college accounting majors should be required to take an ethics course and that the (...) current quality review program should be mandatory, not voluntary. (shrink)

Contextual vocabulary acquisition (CVA) is the deliberate acquisition of a meaning for a word in a text by reasoning from context, where “context” includes: (1) the reader’s “internalization” of the surrounding text, i.e., the reader’s “mental model” of the word’s “textual context” (hereafter, “co-text” [3]) integrated with (2) the reader’s prior knowledge (PK), but it excludes (3) external sources such as dictionaries or people. CVA is what you do when you come across an unfamiliar word in your reading, realize that (...) you don’t know what it means, decide that you need to know what it means in order to understand the passage, but there is no one around to ask, and it is not in the dictionary (or you are too lazy to look it up). In such a case, you can try to figure out its meaning “from context”, i.e., from clues in the co-text together with your prior knowledge. Our computational theory of CVA—implemented in a the SNePS knowledge representation and reasoning system [28]—begins with a stored knowledge base containing SNePS representations of relevant PK, inputs SNePS representations of a passage containing an unfamiliar word, and draws inferences from these two (integrated) information sources. When asked to define the word, definition algorithms deductively search the resulting network for information of the sort that might be found in a dictionary definition, outputting a definition frame whose slots are the kinds of features that a definition might contain (e.g., class membership, properties, actions, spatio-temporal information, etc.) and whose slot-fillers contain information gleaned from the network [6–8,20,23,24]. We are investigating ways to make our system more robust, to embed it in a naturallanguage-processing system, and to incorporate morphological information. Our research group, including reading educators, is also applying our methods to the develop-. (shrink)

A brief introduction to Meinong, his theory of objects, and modern interpretations of it. Sections include: The Theory of Objects, Castañeda's Theory of Guises, Parsons,'s Theory of Nonexistent Objects, Rapaport's Theory of Meinongian Objects, Routley's Theory of Items.

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.

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.

A response to a recent critique by Cem Bozşahin of the theory of syntactic semantics as it applies to Helen Keller, and some applications of the theory to the philosophy of computer science.

Allen Buchanan and Russell Powell have developed a rich ‘biocultural theory’ of the nature and causes of moral progress (and regress) for human beings conceived as evolved rational creatures with a nature characterized by ‘adaptive plasticity’. They characterize their theory as a thoroughly naturalistic account of moral progress, while bracketing various questions in moral theory and metaethics in favor of focusing on a certain range of more scientifically tractable questions under some stipulated moral and metaethical assumptions. While I am very (...) much in agreement with the substance of their project, I wish to query and raise some difficulties for the way it is framed, particularly in connection with the claim of naturalism. While their project is clearly naturalistic in certain senses, it is far from clear that it is so in others that are of particular interest in moral philosophy, and these issues need to be more carefully sorted out. For everything that has been argued in the book, the theory on offer may be only a naturalistic component of a larger theory that must ultimately be non-naturalistic in order to deliver the robust sort of account that is desired. Indeed, there are significant metaethical reasons for believing this to be the case. Moreover, if it turns out that some of the assumptions upon which their theory relies require a non-naturalist metaethics (positing irreducibly evaluative or normative properties and facts) then even the part of the theory that might have seemed most obviously naturalistic, i.e., the explanation of how changes in moral belief and behavior have come about, may actually require some appeal to non-naturalistic elements in the end.

Terence Parsons's informal theory of intentional objects, their properties, and modes of predication does not adequately reflect ordinary ways of speaking and thinking. Meinongian theories recognizing two modes of predication are defended against Parsons's theory of two kinds of properties. Against Parsons's theory of fictional objects, I argue that no existing entities appear in works of fiction. A formal version of Parsons's theory is presented, and a curious consequence about modes of predication is indicated.

This four volume set is a collection of some of the most significant scholarship published on the philosophy of Socrates in the last half century. The contributors include many of the most prominent scholars in this field. As the growth in Socratic studies in the past three decades is due in large part to the influential work of Gregory Vlastos, articles by him figure prominently in the collection, and works by other authors are generally related to his work. The volumes (...) deal with different areas of Socratic thought. The first volume begins with the question whether and to what degree we can discern a distinctive philosophy of Socrates in the ancient sources. The second volume deals with the trial of Socrates and the philosophical issues that arise from it. The third volume considers the philosophical methodology of Socrates and the fourth his moral philosophy. This collection shares some material with earlier collections on the philosophy of Socrates, but it is more extensive and up-to-date. Unlike other collections, which may offer the reader only a single article on a given topic, this collection offers a conversation in-depth. The reader can thus get a sense of the dimensions of the scholarly debate on these central issues in the philosophy of Socrates. No collection can be complete, but this aims at a representative portrait of Socratic studies in the last fifty years. (shrink)

Introduction: characterizing ethical realismIt is useful to begin a survey of recent work on ethical realism with a look at current disputes over what makes a theory of ethics count as ‘realist’ in the first place. Nearly all characterizations of ethical realism include some version of the following two core claims: Ethical discourse is assertoric and descriptive: ethical claims purport to state ethical facts by attributing ethical properties to people, actions, institutions, etc., and are thus true or false depending on (...) whether their descriptions of things are accurate or not . 1 At least some ethical claims, when literally construed, are true in the above sense.Sayre-McCord maintains that these two conditions are necessary and sufficient to characterize ethical realism; others argue that further conditions must be added to yield ethical realism, or at least ‘paradigmatic’ or ‘robust’ ethical realism. Before turning to that, however, it is worth noting that some have recently denied that the above two conditions are even necessary for ethical realism. In probing new work on metaethical taxonomy, Miller argues that the core of ethical realism is simply the metaphysical commitment to objective ethical properties and facts, which is strictly independent of the semantic claims above. If one holds that there are objective facts about the wrongness of slavery, for example, then one ought to count as an ethical realist regardless of whatever views one might hold about the semantics of the contingent forms of discourse that have evolved among language users. Even if our ethical discourse turns out primarily to express conative states ), or all moral claims turn out to be false because …. (shrink)

Although philosophical theologians have sometimes claimed that human beings are necessarily dependent on God, few have developed the idea with any precision. Jonathan Edwards is a notable exception, providing a detailed and often novel account of humanity’s essential ontological, moral, and soteriological dependence on God.

We believe that clinical ethics consultants (CECs) should offer advice, options, and recommendations to attending physicians and their teams. In their article in this issue of The Journal of Clinical Ethics, however, Kornfeld and Prager give CECs a somewhat different role. The CEC they describe may at times be more aptly understood as a medical interventionist who appropriates the roles of the attending physician and the medical team than as a traditional CEC. In these remarks, we distinguish the role of (...) the CEC from that of the physician, in contrast to some of these authors’ recommendations, which confuse the two roles. (shrink)

In this paper I argue against the view of G.E.L. Owen that the second version of the Third Man Argument is a sound objection to Plato's conception of Forms as paradigms and that Plato knew it. The argument can be formulated so as to be valid, but Plato need not be committed to one of its premises. Forms are self-predicative, but the ground of self-predication is not the same as that of ordinary predication.

It is well known that people from other disciplines have made significant contributions to philosophy and have influenced philosophers. It is also true (though perhaps not often realized, since philosophers are not on the receiving end, so to speak) that philosophers have made significant contributions to other disciplines and have influenced researchers in these other disciplines, sometimes more so than they have influenced philosophy itself. But what is perhaps not as well known as it ought to be is that researchers (...) in other disciplines, writing in those other disciplines' journals and conference proceedings, are doing philosophically sophisticated work, work that we in philosophy ignore at our peril. Work in cognitive science and artificial intelligence (AI) often overlaps such paradigmatic philosophical specialties as logic, the philosophy of mind, the philosophy of language, and the philosophy of action. This special issue offers a sampling of research in cognitive science and AI that is philosophically relevant and philosophically sophisticated. (shrink)

All too often, studies of death are reduced to a series of legal or medical case studies, which ignore the need to provide a personal and a societal context. This title explores the practical and philosophical questions related to death and dying. It looks at death from the perspective of different cultures and different periods in history.

John H. Evans’s views on the multiple roles of healthcare ethics consultants are based on his claim that bioethics is a “distinct profession” that has a “system of abstract knowledge.” This response to Professor Evans disputes both of his claims. It is argued that clinical ethicists are consultants but not professionals. Their roles as consultants require more than one abstract form of knowledge (principlism). Instead, clinical ethicists rely upon a variety of ethical perspectives and other skills to help resolve conflicts (...) and facilitate healthcare decisions and policy making, whether it is in clinical, research, policy, or organizational contexts. The credibility and effectiveness of clinical ethicists depend upon their knowledge of ethics, their practical experience, and personal abilities, not one form of abstract knowledge. (shrink)

Equity rights are the rights required for the equitable promotion of life prospects. They include negative opportunity rights, positive opportunity rights, and social insurance rights, including disability insurance, health insurance, retirement insurance, and maintenance rights. Social insurance rights establish a social floor without holes. This explains why they are inalienable and why making them inalienable is not paternalistic. The chapter compares his account with R. Dworkin’s account in terms of social insurance markets. He also compares the social insurance rights endorsed (...) by the main principle with the basic income rights favored by Van Parijs. He explains why Van Parijs’s proposal would have a benefit-spreading effect that would not be endorsed by the main principle. (shrink)
