In the debate over fetal tissue use, an analogy is often drawn between removing organs from the body of a person who has been murdered to use for transplantation, and collecting tissue from an aborted fetus to use for the same purpose. The murder victim analogy is taken by its proponents to show that even if abortion is the moral equivalent of murder, there is still no good reason to refrain from using the fetal tissue, since as a society we (...) do not see any problem about using organs from murder victims. However, I argue that the analogy between murder victims and aborted fetuses does not hold -- the two situations are not the same in all morally relevant respects. Thus the murder victim analogy does not provide an argument in favour of fetal tissue transplant. In conclusion, I point to some of the potential pitfalls of using analogies in ethical argument.

To begin, I take issue with a premiss that Van Cleve explicitly introduce, namely that if change is real, then time is real. Johann Heinrich Lambert had objected to Kant’s view by arguing.

Van Cleve (and J.H. Lambert) argued that if our\nrepresentations change, then time is real. Hence, the\nKantian Analogies presuppose what they mean to prove. Not\nso. For Kant and the common understanding time is a serial\norder that neither loops nor branches and stretches of time\nhave different lengths. The mere change in our\nrepresentations does not by itself provide for duration or\nconnectedness (absence of branching). Rather, the former\nneeds external enduring substances, while causal\nconnections are required to establish connectedness.\nReference is made to Carnap, The Logical Structure (...) of the\nWorld, sects. 87, 120, 171.

This research investigates the development of analogy: In particular, we wish to study the development of systematicity in analogy. Systematicity refers to the mapping of systems of mutually constraining relations, such as causal chains or chains of implication. A preference for systematic mappings is a central aspect of analogical processing in adults (Gentner, 1980, 1983). This research asks two questions: Does systematicity make analogical mapping easier? And, if so, when, developmentally, do children become able to utilize systematicity?Children aged 5–7 and (...) 8–10 acted out stories with toy characters. Then they were asked to act out the same stories with new characters. Two variables were manipulated: systematicity, or the degree of explicit causal structure in the original stories, and the transparency of the object‐mappings. Transparency was manipulated by varying the similarity between the original characters and the corresponding new characters: it was included in order to vary the difficulty of the transfer task. If children can utilize systematicity, then their transfer accuracy should be greater for systematic stories.The results show: (1) As expected, transparency strongly influenced transfer accuracy (for both age groups, transfer accuracy dropped sharply as the object correspondences became less transparent); and (2) for the older group, there was also a strong effect of systematicity and an interaction between the two variables. Given a systematic story, 9‐year‐olds could transfer it accurately regardless of the transparency of the object correspondence. (shrink)

Three experiments investigated whether the similarity of relational structures influences the interpretation of spatial representations. Adults were shown diagrams of hand gestures paired with simple statements and asked to judge the meaning of new gestures. In Experiment 1 the gestures were paired with active declarative statements. In Experiment 2, the gestures were paired with conjunctive and disjunctive relations. Experiment 3 used statements similar to those used in Experiment 1, but eliminated the initial object‐to‐object mapping provided in Experiments 1 and 2. (...) In all three experiments, most participants chose an interpretation that set up a parallel relational structure between the gesture and its meaning: spatial elements were paired with conceptual elements and spatial relations were paired with conceptual relations. These results are consistent with the hypothesis that similarity of relational structures influences spatial reasoning, and have implications for analogical reasoning, diagrammatic reasoning, and language processing.

In lieu of an abstract, here is a brief excerpt of the content:The Renaissance Crisis of ExemplarityFrançois Rigolot“Every example is lame” (Tout exemple cloche), acknowledged Montaigne in the last chapter of his Essais. 1 Was this the moaning of a lone, disillusioned skeptic or the idiosyncratic formulation of a widely shared attitude of mistrust at the end of the sixteenth century? To answer this question one must first examine the epistemological status of examples at the end of the period we (...) still conventionally call the “Renaissance”; and this is the purpose of this group of papers. 2In his work on the notion of exemplum in early modern France and Italy John D. Lyons helped restore the concept of exemplarity to its central place in the history of rhetoric. 3 From Aristotle’s paradeigmata—simple case stories at the orator’s disposal (Rhetoric 1.2. 1356b)—to Montaigne’s “lame” exemples—contingent instances unfit for demonstrative purposes (Essais III, 13, 1070)—the rhetorical impulse has followed strangely circuitous ways. Part of the confusion is probably due to the transformation of technical language under the pressure of common usage. Throughout the early modern period, while the Latin word exemplum continued to refer to rhetorical practice (an illustrative anecdote with a moral point), its vernacular derivatives (esempio, ejemplo, exemple, etc.) generally had a broader, looser, and less didactic meaning, as the emphasis was displaced to the “narrative” aspect of instances, regardless of their intentionality. In other words, although examples were often used to illustrate a didactic point, they differed from exempla inasmuch as they were not always meant to serve a demonstrative purpose.Of course, to the extent that choosing an example necessarily involves some form of selective process from a larger quantity of material, every instance is [End Page 557] bound to entertain a metonymic relation with a greater whole. But, etymologically, an example (essample, in Old French spelling) is a sample, one thing merely alleged to resemble another one, not a demonstrative tool. Yet in his Dictionarie of the French and English Tongues (London, 1611), Randle Cotgrave gave polysemous English equivalents for exemple and exemplaire:Exemple: 1) An example, sample, patterne, or president [sic] to follow; 2) a copie, or counterpane of a writing; 3) one thing alledged to prove, or inforce another that resembles it.Exemplaire: 1) A patterne, sample, or sampler; 2) an example, president [sic] or precedent, for others to follow, or to take heed by; 3) also, the copie, or counterpane of a writing. 4There is an odd mixture of demonstrative and non-demonstrative connotations. The two seemingly interchangeable words receive tripartite definitions, with the three meanings of exemple corresponding to the three of exemplaire.In Renaissance humanistic oratory the evocation of examples was often a simple matter of style. For better elocutory purposes public speakers were encouraged to use graphic case stories to make their speeches more appealing and enjoyable, but orators also used what they called exemplars (Latin exemplaria) to provide their audience with models of conduct to imitate. Worthiness was the ultimate criterion for exemplarity. Cato and Socrates were living symbols of moral determination and courage. They became powerful exemplars of ancient “virtue,” or moral fortitude (Latin virtus; Italian virtù). In the selective process of arguments (inventio), they were chosen because they exemplified a specific attitude or line of conduct: they were, by definition, exemplary examples. 5In the Renaissance the uplifting reading of ancient exemplars was closely related to the doctrine of imitatio, the sacrosanct recourse to inherited cultural models. At the same time the appeal of mimesis, characterized by the actual experience of the real world in reaction to scholastic insularity, greatly problematized the reception of ancient models. Whereas a long-held reverence for the imitative power of traditional exempla offered compelling patterns of moral conduct, the new attractiveness of a more “natural” mimetic discourse [End Page 558] tended to turn the study of models away from duplication. 6 In the face of the inexhaustible diversity and unpredictability of human actions, how can we choose a proper model after which to pattern our own behavior? This is one of the many questions raised by the humanist’s disenchantment with imitative symbols of moral conduct.In recent years the concept... (shrink)

We present a model of similarity‐based retrieval that attempts to capture three seemingly contradictory psychological phenomena: (a) structural commonalities are weighed more heavily than surface commonalities in similarity judgments for items in working memory; (b) in retrieval, superficial similarity is more important than structural similarity; and yet (c) purely structural (analogical) remindings e sometimes experienced. Our model, MAC/FAC, explains these phenomena in terms of a two‐stage process. The first stage uses a computationally cheap, non‐structural matcher to filter candidate long‐term memory (...) items. It uses content vectors, a redundant encoding of structured representations whose dot product estimates how well the corresponding structural representations will match. The second stage uses SME (structure‐mapping engine) to compute structural matches on the handful of items found by the first stage. We show the utility of the MAC/FAC model through a series of computational experiments: (a) We demonstrate that MAC/FAC can model patterns of access found in psychological data; (b) we argue via sensitivity analyses that these simulation results rely on the theory; and (c) we compare the performance of MAC/FAC with ARCS, an alternate model of similarity‐based retrieval, and demonstrate that MAC/FAC explains the data better than ARCS. Finally, we discuss limitations and possible extensions of the model, relationships with other recent retrieval models, and place MAC/FAC in the context of other recent work on the nature of similarity.

Similarly, I define a meta-argument as an argument about one or more arguments, and a ground-level argument as one which is not a meta-argument. (...) Krabbe (1995, in F.H van Eemeren, R. Grootendorst, J.A. Blair, C.A. Willard and A.F. Snoeck Henkemans (eds.), Proceedings of the Third ISSA Conference on Argumentation, Sic Sat, Amsterdam, pp. 333–344) showed that formal-fallacy criticism (and more generally, fallacy criticism) consists of metadialogues, and that such metadialogues can be profiled in ways that lead to their proper termination or resolution. I reconstruct Krabbe’s metadialogical account into monolectical, meta-argumentative terminology by describing three-types of meta-arguments corresponding to the three ways of proving formal invalidity he studied: the trivial logic-indifferent method; the method of counterexample situation; and the method of formal paraphrase. A fourth type of meta-argument corresponds to what Oliver (1967, Mind 76, 463–478), Govier (1985, Informal Logic 7, 27–33), and Copi (1986) call refutation by logical analogy. A fifth type of meta-argument represents my reconstruction of arguments by parity of reasoning studied by Woods and Hudak (1989, Informal Logic 11, 125–139). Other particular meta-arguments deserving future study are Hume’s critique of the argument from design in the Dialogues Concerning Natural Religion, and Mill’s initial argument in The Subjection of Women about the importance of established custom and general feeling vis-à-vis argumentation.

An important problem in inductive probability theory is the design of exchangeable analogical methods, i.e., of exchangeable inductive methods that take into account certain considerations of analogy by similarity for predictive inferences. Here a precise reformulation of the problem of predictive analogy is given and a new family of exchangeable analogical methods is introduced.Firstly, it is proved that the exchangeable analogical method introduced by Skyrms (1993) does not satisfy the best known general principles of predictive analogy. Secondly, Skyrms's approach — (...) consisting of the usage of particular hyper-Carnapian methods, i.e., mixtures of Carnapian inductive methods — is adopted in the design of a new family of exchangeable analogical methods. Lastly, it is proved that such methods satisfy an interesting general principle of predictive analogy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 28, Number 1, April 2002, pp. 113-130 Bayesianism, Analogy, and Hume's Dialogues concerning Natural Religion SALLY FERGUSON Introduction Analyses of the argument from design in Hume's Dialogues concerning Natural Religion have generally treated that argument as an example of reasoning by analogy.1 In this paper I examine whether it is in accord with Hume's thinking about the argument to subsume the version of it given in (...) the Dialogues under the model of probabilistic reasoning offered by Bayes's theorem. Wesley Salmon attempted this project in 1978.2 In related projects, David Owen3 as well as Philip Dawid and Donald Gillies4 have more recently attempted to construct Bayesian analyses of Hume's argument concerning testimony in "Of Miracles." I want to be careful at this stage to note exactly what I will claim. It is not that Bayesian reasoning sheds no light on the argument from design, or on arguments concerning testimony. All of the analyses mentioned above are beneficial in that they have been able to expose subtleties in these arguments that had previously gone unnoticed. Salmon's paper, in particular, contributes nicely to an understanding of just how the design argument may function in relation to contemporary scientific reasoning. In this paper I argue that, nonetheless, the attempt to apply Bayesian reasoning to the argument as presented in the Dialogues is not well supported as a reconstruction of Hume's own approach to the argument from design. Sally Ferguson is Assistant Professor of Philosophy, University of West Florida, UOOO University Parkway, Pensacola, FL 32514, USA. e-mail: [email protected] 114 Sally Ferguson There are two stages to my treatment of the issue. I begin by considering how much Hume knew of Bayes's theorem, and what consequence that knowledge might have had on his treatment of the argument in the Dialogues. This discussion includes a consideration of exactly what has been claimed by other authors on this subject, including what some have argued concerning Hume's reasonings in "Of Miracles," section 10 of An Enquiry concerning Human Understanding. I conclude that, based on the historical data, there is little reason to think of Hume's approach to the argument from design as anything more than proto-Bayesian at best. I then argue further, through a close textual analysis of the Dialogues, that there are good reasons for not treating Hume's reasoning there as even proto-Bayesian. In the end, the benefits that have been claimed for that approach, in terms of exposing both the subtleties of the argument and of Hume's reasoning about it, can equally well be derived from a careful analysis of the argument under a model of analogical reasoning, without need of Bayes's theorem. Section One Perhaps one might think that there is not much use for a consideration of the question whether Hume himself conceived of any of his arguments along specifically Bayesian lines. As Gower argues,5 Hume's knowledge of mathematics in general was fairly limited, and Bayes's theorem was not well known even up until Hume's death. It is important, therefore, for me to establish that there have not only been those who thought that Bayesian reasoning illuminates the arguments Hume gave, but also his own thinking about those arguments. It is also important for me to establish that it is not obvious that knowledge of Bayes's theorem did not affect Hume's reasonings. Each of these points will be addressed in the following. As to the first point, the claims of some authors on the subject are ambiguous. Dawid and Gillie, for example, make no statement to the effect that the probabilities involved in Bayes's theorem were in fact examined in "Of Miracles," nor do they attempt to produce any passages from Hume in support of that view. Thus it would be assumed that they see their attempt not as an attempt to provide an analysis that represents Hume's own approach to the argument, but rather simply as one that provides an illuminating method of analysis and support for an argument that Hume happened to give. Indeed, their conclusion, to the effect that a... (shrink)

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

Conceptual integration—“blending”—is a general cognitive operation on a par with analogy, recursion, mental modeling, conceptual categorization, and framing. It serves a variety of cognitive purposes. It is dynamic, supple, and active in the moment of thinking. It yields products that frequently become entrenched in conceptual structure and grammar, and it often performs new work on its previously entrenched products as inputs. Blending is easy to detect in spectacular cases but it is for the most part a routine, workaday process that (...) escapes detection except on technical analysis. It is not reserved for special purposes, and is not costly.In blending, structure from input mental spaces is projected to a separate, “blended” mental space. The projection is selective. Through completion and elaboration, the blend develops structure not provided by the inputs. Inferences, arguments, and ideas developed in the blend can have effect in cognition, leading us to modify the initial inputs and to change our view of the corresponding situations.Blending operates according to a set of uniform structural and dynamic principles. It additionally observes a set of optimality principles. (shrink)

In the section called “Observation of Nature” in the Phenomenology of Spirit, Hegel considers and criticizes a particular form of methodology which seeks final purposes by analogy. Through this methodology what is essential for thought is the recognition and demarcation of differentiae, which are imputed to natural objects as qualities by which things maintain their distinct and separate character - what Hegel calls their “being-for-self.” By these differentiae, then, the objects are categorized into types, or “natural kinds,” which, in turn, (...) are interpreted by natural philosophers according to a projected teleological system. Hegel’s critique is not aimed primarily at the categorization of objects, but at the method of interpretation used to characterize these categories as purposeful. In particular, Hegel is not criticizing the use of analogy as discussed in the biological writings of Aristotle, but the use of analogy by the transcendental idealists, especially Kant, who employs this method in the Critique of Judgment.

In this paper we present Drama, a distributed model of analogical mapping that integrates semantic and structural constraints on constructing analogies. Specifically, Drama uses holographic reduced representations (Plate, 1994), a distributed representation scheme, to model the effects of structure and meaning on human performance of analogical mapping. Drama is compared to three symbolic models of analogy (SME, Copycat, and ACME) and one partially distributed model (LISA). We describe Drama's performance on a number of example analogies and assess the model in (...) terms of neurological and psychological plausibility. We argue that Drama's successes are due largely to integrating structural and semantic constraints throughout the mapping process. We also claim that Drama is an existence proof of using distributed representations to model high‐level cognitive phenomena. (shrink)

Rahner is not based on a conceptual or semantic distinction but on the ontological constitution of human transcendence. From Rahner’s perspective, Taylor’s critique is faulty because it springs from an impoverished view of Being and a diminished sense of the radical nature of human transcendence. While Taylor’s critique does not undermine Rahner’s position, it alerts one to the propensity of his position to generate substantialized interpretations and, at times, Rahner’s own tendency to dissolve too quickly dialectical tensions within his position.
