In lieu of an abstract, here is a brief excerpt of the content:NECESSARY PROPOSITIONS AND THE SQUARE OF OPPOSITION MARK ROBERTS University of Rhode Island Kingston, Rhode Island IT IS COMMONPLACE to define contradictory, contrary, and subcontrary propositions in the following way: contradictory propositions cannot both be true and cannot both be false; contrary propositions cannot both be true but can both be false; and subcontrary propositions can both be true but cannot both be false. In his Introduction to Logic (...) 1 Irving Copi raises a problem with two of these definitions which he believes forces him to limit the range of propositions which can be used in the square of opposition. Since contrary propositions can both be false, but the falsity of a necessarily true proposition is not possible, a necessarily true proposition has no contrary. Therefore, only contingent propositions can be contraries. Subcontrary propositions can both be true, but the truth of a necessarily false proposition is not possible.2 This problem is rarely raised in other logic texts, but, it is interesting to note, it is mentioned by a number of neoscholastic philosophers, for example, P. Nicholas Russo,3 Rev. H. Grenier,4 1 Irving M. Copi, Introduction to Logic (New York: Macmillan, 1986), pp. 178-179. Copi first introduced this problem in the fifth edition of his work on the basis of an article by David H. Sanford entitled " Contraries and Subcontraries,'' Nous 2 (1968) : 95-96. Sanford argues that the most reasonable way to resolve the problem of necessary propositions is to assume that contingent propositions comprise the square of opposition. 2 Copi, pp. 178-179. 8 Nicholas Russo, Summa Philosophica (Boston: Apud Marlier et Socios, 1[;85), p. 23. 4 Henri Grenier, Thomistic Philosophy, Vol. I (Charlottetown, Canada: St. Dunstan's University, 1950), p. 69. 427 428 MARK ROBERTS G. Sanseverino,5 Jacques Maritain,6 F.-X. Maquart,7 P. Coffey,8 and others.9 (It is also mentioned by Bishop Whately.10 ) Each of these philosophers makes necessarily true or false propositions an exception to the definition of contrary and subcontrary propositions. The reason is they and Copi interpret the definitions of contrary and subcontrary propositions to mean that the falsity of each contrary proposition is possible and the truth of each subcontrary proposition is possible. It should be mentioned, however, that the position of the philosophers cited above is not entirely the same as Copi's. Copi reasons that these definitions imply that necessary propositions have no contrary or subcontrary. The other philosophers believe that necessary propositions can be contraries and subcontraries. Thus, in the case of necessary propositions contrary and subcontrary propositions are, instead, defined merely in terms of their quantity and quality, not by whether or not they can both be false or can both be true. In fact, Coffey and some of the other philosophers cited above assert that, when the propositions composing the square are necessary, one can infer the truth of the universal from the truth of 5 Gaietano Sanseverino, Philosophia Christiana, Vol. II (Neapoli: Vincentii Manfredi, 1862), pp. DCCXXXVIII ff. 6 J.

This book offers an in-depth analysis of the wide range of issues surrounding "passive euthanasia" and "allow-to-die" decisions. The author develops a comprehensive conceptual model that is highly useful for assessing and dealing with real-life situations. He presents an informative historical overview, an evaluation of the clinical settings in which treatment abatement takes place, and an insightful discussion of relevant legal aspects. The result is a clearly articulated ethical analysis that is medically realistic, philosophically sound, and legally viable.

In this essay it is argued that (1) if the process of scientific inquiry were to continue foreever, then science would ultimately terminate in the acceptance of a single theoretical framework better than all conceivable others, and (2) there is some evidence in favor of the view that science will continue unto eternity but no evidence in favor of the contrary view. In arguing for claim (1) it is claimed that if we are to understand the sense in which science (...) is progressive we must mean either that science progresses by approximating a final goal which, given an infinite process, will be attained, or that science progresses simply in the sense of expanding a body of funded knowledge such that, given an infinite process, the body of funded knowledge expands ad infinitum. That the second member of this disjunct is false and that the first cannot be shown to be false follows largely from a discussion and rejection of all available arguments (five) against the hypothesis proposed in (1). Further, an argument provided by Peirce (and suitably supplemented) provides additional positive evidence for the truth of the first member. No such argument exists for the truth of the second member. In arguing for claim (2) it is held that evidence in favor of a belief can be purchased by the positive moral value likely to occur as a result of accepting the beliefs, and that there is at least one moral value which accrues to the belief that inquiry will continue forever but which does not accrue to the belief that inquiry will not continue forever. In short, while there is no systematic evidence for or against the view that inquiry will continue forever, we have the right (and duty) to believe that inquiry will continue forever but we do not have the right (and duty) to believe the contrary.

Blind Realism originated in the deeply felt conviction that the widespread acceptance of Gettier-type counterexamples to the classical definition of knowledge rests in a demonstrably erroneous understanding of the nature of human knowledge. In seeking to defend that conviction, Robert F. Almeder offers a fairly detailed and systematic picture of the nature and limits of human factual knowledge.

The current conflict between the recording industry and a portion of its customers who are involved in illicit copying of music files arose from innovations involving the compression and electronic distribution of files over the internet. This paper briefly describes some of the challenges faced by the recording industry, and examines some of the ethical issues that arise in various industry and consumer responses to the opportunities and threats presented by these innovations. The paper concludes by highlighting the risks associated (...) with responses that threaten further innovation, ultimately reducing the chances of finding solutions that hold appeal for all parties.

The participation of adolescents in genetic research engenders unusual problems concerning the nature of their informed consent. In this study we analyze 70 consent documents collected from genetics investigators in the United States who conduct research with children and adolescents. We find that many consent documents do not reflect either the current or the developing ethical and legal standards for research with adolescents and that in many cases the documents are simply confusing or unclear. We make recommendations for change to (...) reflect more adequately the changing perspective concerning the autonomous decision-making capacity of adolescents. (shrink)

Robert Almeder provides a comprehensive discussion and definitive refutation of our common conception of truth as a necessary condition for knowledge of the world, and to defend in detail an epistemic conception of truth without falling into the usual epistemological relativism or classical idealism in which all properties of the world turn out to be linguistic in nature and origin. There is no other book available that clearly and thoroughly defends the case for an epistemic conception of truth and (...) also claims success in avoiding idealism or epistemological relativism.

This paper builds upon previous work in which I argue that we should assess a provider's reasons for his or her objection before granting a conscientious exemption. For instance, if the medical professional's reasoned basis involves an empirical mistake, an accommodation is not warranted. This article poses and begins to address several deep questions about the workings of what I call a reason-giving view: What standard should we use to assess reasons? What policy should we adopt in order to evaluate (...) the reasons offered by medical practitioners in support of their objections? I argue for a reasonability standard to perform the essential function of assessing reasons, and I offer considerations in support of a policy establishing conscientious objector status in medicine.

This article argues that practitioners have a professional ethical obligation to dispense emergency contraception, even given conscientious objection to this treatment. This recent controversy affects all medical professionals, including physicians as well as pharmacists. This article begins by analyzing the option of referring the patient to another willing provider. Objecting professionals may conscientiously refuse because they consider emergency contraception to be equivalent to abortion or because they believe contraception itself is immoral. This article critically evaluates these reasons and concludes that (...) they do not successfully support conscientious objection in this context. Contrary to the views of other thinkers, it is not possible to easily strike a respectful balance between the interests of objecting providers and patients in this case. As medical professionals, providers have an ethical duty to inform women of this option and provide emergency contraception when this treatment is requested. (shrink)

This is a book about the role that psychological impairment should play in a theory of criminal liability. Criminal guilt in the Anglo-American legal tradition requires both that the defendant committed some proscribed act and did so with intent, knowledge, or recklessness. The second requirement corresponds to the intuitive idea that people should not be punished for something they did not do 'on purpose' or if they 'did not realize what they were doing'. Unlike many works in this area, this (...) book addresses the automatism and insanity defences by examining the types of functional impairment that typical candidates for these defences actually suffer. What emerges is a much wider conceptual framework that allows us to understand the significance of psychological states and processes for the attribution of criminal responsibility in a manner that is logically coherent, morally defensible, and consistent with research in psychopathology.

Robert Dobbin presents a new translation into clear modern English of the first book of Epictetus' Discourses, accompanied by the first ever commentary on the work in English. The Discourses, composed around AD 100, are a key source for ancient Stoicism, one of the most influential schools of thought in Western philosophy.

A powerful objection to impersonal moral theories states that they cannot accommodate the good of friendship. This paper focuses on the problem as it applies to consequentialism and addresses the recent criticism that even the most sophisticated forms of consequentialism are incompatible with genuine friendship. I argue that this objection fails since those who pose this challenge either seriously oversimplify consequentialism's theory of value, misunderstand its theory of practical reason, or put too much weight on the good of friendship itself. (...) I conclude by assessing a contemporary consequentialist response in order to suggest a workable conception of consequentialist friendship. (shrink)

The identity of the Caesar at "Aeneid", 1.286 is a long-standing problem. The prevailing opinion since Heyne favors Augustus, but a few scholars agree with Servius that the Dictator is meant. In recent years the suggestion that Vergil was being deliberately ambiguous has been advanced as a solution to the problem. I argue the case for Julius Caesar anew. The paper is in five sections. The first four deal respectively with the question of nomenclature; chronology; the descriptive epithets applied to (...) Caesar, especially spoliis Orientis onustum in 289; and the rhetoric of the passage. The fourth section confronts the challenge posed to my reading by the well-known view of Ronald Syme, held to throughout his lifetime, that Julius Caesar was a virtual non-person in the Rome of Vergil's day because the princeps tried to avoid awkward comparison with the Dictator. But this view has been challenged, and I draw on recent work in this area. In the fifth and final section I support my reading with references to Vergil's earlier poetry, attending especially to what it can tell us about Vergil's attitude toward Julius Caesar. Of particular relevance is the use he makes of the sidus Iulium, an image found in the Eclogues and important in connection with the apocalyptic outlook abroad at the time of Caesar's assassination. This section of the paper expands on Servius' generally neglected note, which maintains that the Caesar in question is Julius. (shrink)

In their provocative 1988 paper, Fodor and Pylyshyn issued a formidable challenge to connectionists, i.e. to provide a non‐classical explanation of the empirical phenomenon of systematicity in cognitive agents. Since the appearance of F&P's challenge, a number of connectionist systems have emerged which prima facie meet this challenge. However, Fodor and McLaughlin (1990) advance an argument, based upon a general principle of nomological necessity, to show that one of these systems (Smolensky's) could not satisfy the Fodor‐Pylyshyn challenge. Yet, if Fodor (...) and McLaughlin's analysis is correct, it is doubtful whether any existing connectionist system would fare better than Smolensky's. In the view of Fodor and McLaughlin, humans and classical architectures display systematicity as a matter of nomological necessity (necessity by virtue of natural law), but connectionist architectures do not. However, I argue that the Fodor‐Pylyshyn‐McLaughlin appeal to nomological necessity is untenable. There is a sense in which neither classical nor connectionist architectures possess nomological (or‘nomic’) necessity. However, the sense in which classical architectures do possess nomic necessity applies equally well to at least some connectionist architectures. Representational constituents can have causal efficacy within both classical and connectionist architectures. (shrink)

This landmark volume brings together the work of the world's leading researchers in sublimated perception. This compilation marks a fundamental shift in the current study of subliminal effects: No longer in question is the notion that perception without awareness occurs. Now, the emphasis is on elucidating the parameters of subliminal effects and understanding the conditions under which stimuli perceived without awareness significantly influence affect, cognition, and behavior. PERCEPTION WITHOUT AWARENESS firmly establishes subliminal perception within the mainstream of psychological science. Well (...) represented here are the two main research branches that have emerged: One directly investigates the nature of subliminal effects; the other uses subliminal techniques as tools for investigating psychological phenomena such as hypnosis, dreaming, repression, social judgment and inference, psychopathology, and symptom formation. Broadly grouped into three main sections, the contributed chapters explore * The cognitive perspective--including implicit memory and implicit perception, the measurement of unconscious perceptual processes, and methods for revealing unconscious processes * The clinical perspective--exploring the cognitive and dynamic aspects of subliminal perception, memory, and consciousness; direct recovery of subliminal stimuli; and validation of subliminal psychodynamic activation * The social perspective--discussing subliminal mere-exposure effects, affect and social perception, and the role of subliminality in social psychology Timely and thought-provoking, PERCEPTION WITHOUT AWARENESS is sure to be of enormous interest to all psychoanalytic clinicians and scholars, as well as cognitive, clinical, and social psychologists whose work touches upon issues relating to psychopathology, perception, cognition, and memory.

Much of traditional AI exemplifies the explicit representation paradigm, and during the late 1980''s a heated debate arose between the classical and connectionist camps as to whether beliefs and rules receive an explicit or implicit representation in human cognition. In a recent paper, Kirsh (1990) questions the coherence of the fundamental distinction underlying this debate. He argues that our basic intuitions concerning explicit and implicit representations are not only confused but inconsistent. Ultimately, Kirsh proposes a new formulation of the distinction, (...) based upon the criterion ofconstant time processing.The present paper examines Kirsh''s claims. It is argued that Kirsh fails to demonstrate that our usage of explicit and implicit is seriously confused or inconsistent. Furthermore, it is argued that Kirsh''s new formulation of the explicit-implicit distinction is excessively stringent, in that it banishes virtually all sentences of natural language from the realm of explicit representation. By contrast, the present paper proposes definitions for explicit and implicit which preserve most of our strong intuitions concerning straightforward uses of these terms. It is also argued that the distinction delineated here sustains the meaningfulness of the abovementioned debate between classicists and connectionists. (shrink)

The situationist challenge to global character traits claims that on the basis of findings in social psychology, we should only accept at most the existence of local or context-sensitive traits. In this article I explore a neglected area of J. S. Mill's work to outline an account of context-sensitive traits. This account of traits, coupled with a sophisticated consequentialist ethical framework, suggests an interesting view on which persons govern the circumstances of their actions in order to best promote overall well-being.

Adolescents who are critically, chronically, and terminally ill traditionally have been given little voice in their health care treatment. But over the last three decades attitudes have begun to shift. The legal and medical professions as well as parents and children's advocates have started to recognize that cognitively normal adolescents have decisionmaking capacity and believe these patients ought to have the opportunity to participate in even the toughest of health treatment decisions. Advance directives, if used with sensitivity and care, could (...) prove a valuable means of giving these older pediatric patients a say in their care. (shrink)

No-arbitrage is the fundamental principle of economic rationality which unifies normative decision theory, game theory, and market theory. In economic environments where money is available as a medium of measurement and exchange, no-arbitrage is synonymous with subjective expected utility maximization in personal decisions, competitive equilibria in capital markets and exchange economies, and correlated equilibria in noncooperative games. The arbitrage principle directly characterizes rationality at the market level; the appearance of deliberate optimization by individual agents is a consequence of their adaptation (...) to the market. Concepts of equilibrium behavior in games and markets can thus be reconciled with the ideas that individual rationality is bounded, that agents use evolutionarily-shaped decision rules rather than numerical optimization algorithms, and that personal probabilities and utilities are inseparable and to some extent indeterminate. Risk-neutral probability distributions, interpretable as products of probabilities and marginal utilities, play a central role as observable quantities in economic systems. (shrink)

As an introduction to explicating the concept of basic knowledge, I shall examine Aristotle's argument for the existence of basic knowledge and urge two basic points. The first point is that Aristotle's argument, properly viewed, establishes the existence of a kind of knowledge, basic or non-demonstrative knowledge, the definition of which does not require the specification of, and hence the satisfaction of,anyevidence condition. This point has been urged by philosophers like Peirce and Austin but it needs further argumentation because most (...) analytic epistemologists still insist thatallknowledge, whether basic or non-basic, requires the satisfaction of some evidence condition. Secondly, to urge that the basic propositions whose existence is established by Aristotle's argument could be privileged but not known, for the reason that there is no evidence condition for them, would be to adopt a position that either entails wholesale skepticism or undermines the basic distinction between knowledge and belief.

De Finetti's treatise on the theory of probability begins with the provocative statement PROBABILITY DOES NOT EXIST, meaning that probability does not exist in an objective sense. Rather, probability exists only subjectively within the minds of individuals. De Finetti defined subjective probabilities in terms of the rates at which individuals are willing to bet money on events, even though, in principle, such betting rates could depend on state-dependent marginal utility for money as well as on beliefs. Most later authors, from (...) Savage onward, have attempted to disentangle beliefs from values by introducing hypothetical bets whose payoffs are abstract consequences that are assumed to have state-independent utility. In this paper, I argue that de Finetti was right all along: PROBABILITY, considered as a numerical measure of pure belief uncontaminated by attitudes toward money, does not exist. Rather, what exist are de Finetti's `previsions', or betting rates for money, otherwise known in the literature as `risk neutral probabilities'. But the fact that previsions are not measures of pure belief turns out not to be problematic for statistical inference, decision analysis, or economic modeling. (shrink)

Elizabeth Anderson claims that states of affairs are merely extrinsically valuable, since we value them only in virtue of the intrinsically valuable persons in those states of affairs. Since it considers states of affairs to be the sole bearers of intrinsic value, Anderson argues that consequentialism is incoherent because it attempts to globally maximize extrinsic value. I respond to this objection by distinguishing between two forms of consequentialist teleology and arguing that Anderson''s claim is either harmless or her argument for (...) the claim is uncompelling. On the first conception of teleology, consequentialists need not hold that states of affairs are the sole bearers of intrinsic value, which allows them to deflect this criticism. On the second account of teleology, even assuming that states of affairs are the sole bearers of intrinsic value, Anderson''s argument does not necessarily defeat such views. (shrink)

Transhumanism and Extropianism are two recent ‘movements’ which aspire to transcend the perceived limitations of human biological evolution. This paper takes a critical look at two of the most controversial aspects of Extropianism—Uploading and Immortality. Uploading is the process by which a human will be able to transfer the entire contents of their brain to a more suitable supercomputational medium. When the newentity exist as software, immortality is virtually assured. This should be possible, it is claimed, within the next fifty (...) years! From both a pragmatic and philosophical perspective, I argue that these claims are at best misguided and at worst absurd. (shrink)
