In the Critique of the Teleological Power of Judgment Kant argues that organisms have inner purposiveness. He introduces inner purposiveness in contrast to relative purposiveness. I examine Kant’s discussion of relative purposiveness in §63. I then argue that Kant establishes three theses in §63 that he subsequently modifies in §64 and further refines in §65. In my view, his discussion of relative purposiveness serves a broader purpose than just to present a contrast from which to consider inner (...) purposiveness. The discussion of relative purposiveness establishes a framework for a sustained thread of argument from §63 through §65, culminating in Kant’s often discussed claim that we must judge organisms to be natural ends. My interpretation exposes a more significant argumentative role for relative purposiveness than is typically recognized. (shrink)

In this paper, we consider the relative significance of concrete and abstract features for the identity and persistence of a group. The theoretical background for our analysis is the position according to which groups are realizations of structures. Our main argument is that the relative significance of the abstract features with respect to the significance of concrete features can vary across different types of groups. The argumentation will be backed by introducing the examples in which (...) we show that this difference in significance can affect the identity and persistence of the group. (shrink)

In the fields of linguistics and psychology the didactic implementation of new knowledge relative to argumentative discourse and its acquisition has led us to develop a didactic sequence focused on the teaching of argumentation in 11–12 year old pupils. This sequence was experimented in six schools in order to assess the effect of these new educational methods on the capacities of pupils to treat the dialogic dimensions of argumentation in the writing of monologues. An analysis of the productions of (...) the puils who had been submitted to the didactic sequence, compared with those of a control group, showed a significant improvement in the capacities of the first group. These improvements concerned aspects such as backing up arguments, acknowledging the addressee, negotiating with an eventual contradictor and using of a certain number of units and linguistic expressions t specific to argumentative texts (expressions of responsability taking, textual organisers of cause and conclusion, modalisations of probability and of certitude, concessions and polite expressions).

The special theory of relativity (STR) is widely supposed to be in tension with A-theories of time, those giving special significance to the present moment. A-theories are diverse in the features they regard as distinctive of the present, but all agree that there is an absolute fact of the matter about which events have the feature of presentness. Famously, the standard notion of simultaneity operationalised within the theory of relativity is not absolute. If A-theorists accept relativistic physics, they must (...) either refine their A-theory and sever joint presentness from simultaneity (‘conciliatory’ responses to the problem), or supplement standard relativity by adding further spacetime structure that grounds a relation of absolute simultaneity (‘supplementing’ responses). This chapter considers the prospects for such approaches, concluding that while there is no knock-down argument from relativity against the A-theory, attempts to marry the A-theory with STR are more trouble than they are worth.

According to the popular Grounded Cognition Model (GCM), the sensory and motor features of concepts, including word meanings, are stored directly within neural systems for perception and action. More precisely, the core claim is that these concrete conceptual features reuse some of the same modality-specific representations that serve to categorize experiences involving the relevant kinds of objects and events. Research in semantic typology, however, has shown that word meanings vary significantly across the roughly 6500 languages in the world. I argue (...) that this crosslinguistic semantic diversity has significant yet previously unrecognized theoretical consequences for the GCM. In particular, to accommodate the typological data, the GCM must assume that the concrete features of word meanings are not merely stored within sensory/motor brain systems, but are represented there in ways that are, to a nontrivial degree, language-specific. Moreover, it must assume that these conceptual representations are also activated during the nonlinguistic processing of the relevant kinds of objects and events (e.g., during visual perception and action planning); otherwise, they would not really be grounded, which is to say, embedded inside sensory/motor systems. Crucially, however, such activations would constitute what is traditionally called linguistic relativity—that is, the influence of language-specific semantic structures on other forms of cognition. The overarching aim of this paper is to elaborate this argument more fully and explore its repercussions. To that end, I discuss in greater detail the key aspects of the GCM, the evidence for crosslinguistic semantic diversity, pertinent work on linguistic relativity, the central claim that the GCM entails linguistic relativity, some initial supporting results, and some important limitations and future directions.

The New Rhetoric is founded on the idea that since “argumentation aims at securing the adherence of those to whom it is addressed, it is, in its entirety, relative to the audience to be influenced,” says Chaïm Perelman and L. Olbrechts-Tyteca, and they rely, in particular, for their theory of argumentation on the twin concepts of universal and particular audiences: while every argument is directed to a specific individual or group, the orator decides what information and what approaches will (...) achieve the greatest adherence according to an ideal audience. This ideal, Perelman explains, can be embodied, for example, "in God, in all reasonable and competent men, in the man deliberating or in an elite.” Like particular audiences, then, the universal audience is never fixed or absolute but depends on the orator, the content and goals of the argument, and the particular audience to whom the argument is addressed. These considerations determine what information constitutes "facts" and "reasonableness" and thus help to determine the universal audience that, in turn, shapes the orator's approach. /// The adherence of an audience is also determined by the orator's use of values, a further key concept of the New Rhetoric. Perelman's treatment of value and his view of epideictic rhetoric sets his approach apart from that of the ancients and of Aristotle in particular. Aristotle's division of rhetoric into three genres–forensic, deliberative, and epideictic–is largely motivated by the judgments required for each: forensic or legal arguments require verdicts on past action, deliberative or political rhetoric seeks judgment on future action, and epideictic or ceremonial rhetoric concerns values associated with praise or blame and seeks no specific decisions. For Aristotle, the epideictic genre was of limited importance in the civic realm since it did not concern facts or policies. Perelman, in contrast, believes not only that epideictic rhetoric warrants more attention, but that the values normally limited to that genre are in fact central to all argumentation. "Epideictic oratory," Perelman argues, "has significant and important argumentation for strengthening the disposition toward action by increasing adherence to the values it lauds.” These values are central to the persuasiveness of arguments in all rhetorical genres since the orator always attempts to "establish a sense of communion centered around particular values recognized by the audience.”.

The cis-regulatory hypothesis is one of the most important claims of evolutionary developmental biology. In this paper I examine the theoretical argument for cis-regulatory evolution and its role within evolutionary theorizing. I show that, although the argument has some weaknesses, it acts as a useful example for the importance of current scientific debates for science education.

Contrary to the received view according to which the value of works of art consists exclusively or primarily in their aesthetic value I argue that the importance of aesthetic value has been grossly overrated. In earlier publications I have shown that the assumption stipulating that the value of artworks consists exclusively in their aesthetic value is demonstrably wrong. I have suggested a conceptual distinction between the aesthetic and the artistic value arguing that when it comes to evaluation the artistic value, (...) which reflects the significance of innovations exemplified by the work, is no less important than the aesthetic value. Here I take the argument a step further by suggesting that the aesthetic value is considerably less important than the artistic value. To show this I draw attention to a neglected aspect of art evaluation, namely to the monetary value of artworks. Although there is no necessary connection between monetary value of works of art and their aesthetic value or their artistic value, it can nevertheless tell us something important not only about the overall value of works of art but also about the relative importance of the two component values. I show that the enormous differences between monetary values of different artworks cannot be accounted for by the corresponding differences in their aesthetic value but can be explained by the differences in their artistic value.

Supposing that one is already familiar with special relativistic physics, what constitutes the best route via which to arrive at the architecture of the general theory of relativity? Although the later Einstein would stress the significance of mathematical and theoretical principles in answering this question, in this article we follow the lead of the earlier Einstein (circa 1916) and stress instead how one can go a long way to arriving at the general theory via inductive and empirical principles, without (...) invoking presumptions concerning the geometrical structure of the final theory. We focus on the construction of the kinematical structure and the terms describing the coupling of matter to gravity. General covariance, understood and employed as a straightforward extrapolation of empirical considerations, is central to our derivation, together with what we dub the `Methodological Equivalence Principle'. We argue that our approach has a number of virtues, both for one's understanding of the general theory of relativity, but also for pedagogy, since it stresses---to the greatest extent possible (a lesson which we inherit from Bell, [1976])---both the methodological precedence of dynamical considerations to interpretative issues and the theoretical continuity between general relativity and its precursors. We conclude by comparing our approach to other philosophical approaches to general relativity and discussing the significance of empirically motivated methodological principles in the philosophy of science.

We draw out significant consequences of a relatively popular theory of metaphysical modality—branching actualism—for cosmological arguments for God’s existence. According to branching actualism, every possible world shares an initial history with the actual world and diverges only because causal powers (or dispositions, or some such) are differentially exercised. We argue that branching actualism undergirds successful responses to two recent cosmological arguments: the Grim Reaper Kalam argument and a modal argument from contingency. We also argue that branching actualism affords (...) a response to one popular defense of the classic contingency argument. What results are new difficulties for several cosmological arguments arising from the metaphysics of modality. (shrink)

In spite of significant research efforts, argument technologies do not seem poised to scale up as much as most commentators would hope or even predict. In this paper, I discuss what obstacles bar the way to more widespread success of argument technologies and venture some suggestions on how to circumvent such difficulties: doing so will require a significant shift in how this research area is typically understood and practiced. I begin by exploring a much broader yet closely related question: To (...) what extent are people natively good at arguing? This issue has always been central to philosophical reflection and it has become even more urgent nowadays, with the explosion of persuasive technologies and unprecedented opportunities for large-scale social influence. The answer hinges on what aspect of argumentation is taken under consideration: evidence suggests that people are relatively bad at analyzing the structure of arguments, especially when these are presented out of context and in abstract terms; in contrast, data show that even laymen tend to excel in the interactive practice of argumentation, in particular when motivation is high and something significant is at stake. Unfortunately, current argument technologies are more closely tailored to the former type of activity than to the latter, which is the main reason behind their relative lack of success with the general public. Changing this state of affair will require a commitment to ecological argument technologies: that is, technologies designed to support real-time, engaging and meaningful argumentative interactions performed by laypeople in their ordinary life, instead of catering to the highly specific needs of a minority of niche users.

The problem that suffering and other evils pose for the rationality of belief in an omnipotent, omniscient, and morally perfect person has been the focus of intense discussion for a long time. The main thing that I want to do here is to consider whether recent discussions have significantly advanced our understanding of the underlying issues. I believe that they have, and I shall try to indicate the ways in which that is so. The structure of my discussion is as (...) follows. The first two sections constitute the main part of the paper. In the first section, I shall consider how the argument from evil might best be formulated. Among the topics that I shall discuss are, first, the distinction between abstract and concrete formulations of the argument from evil; secondly, the distinction between incompatibility and evidential formulations; thirdly, the distinction between subjective and objective formulations; and fourthly, the relevance to the argument from evil of traditional arguments in support of the existence of God. One of my conclusions in the first section is that the argument from evil is best viewed as consisting of a core argument that is relatively straightforward – with the exception of one crucial premise – plus a subsidiary argument designed to support the premise in question. The second section will therefore be devoted to an examination of that subsidiary argument. In the third section, I shall consider different types of responses to the argument from evil. One useful classification, I suggest, is in terms of whether the goal is that of a total refutation of the argument, a defense, or a theodicy. In subsequent sections, I consider those options, and I show that none is successful. (shrink)

Relativity Theory by Albert Einstein has been so far littleconsidered by cognitive scientists, notwithstanding its undisputedscientific and philosophical moment. Unfortunately, we don't have adiary or notebook as cognitively useful as Faraday's. But physicshistorians and philosophers have done a great job that is relevant bothfor the study of the scientist's reasoning and the philosophy ofscience. I will try here to highlight the fertility of a `triangulation'using cognitive psychology, history of science and philosophy of sciencein starting answering a clearly very complex question:why (...) did Einstein discover Relativity Theory? Here we arenot much concerned with the unending question of precisely whatEinstein discovered, that still remains unanswered, for we have noconsensus over the exact nature of the theory's foundations. We are mainly interested in starting to answer the`how question', and especially the following sub-question: what were his goals and strategies in hissearch? I will base my argument on fundamental publications ofEinstein, aiming at pointing out a theory-specific heuristic, settingboth a goal and a strategy: covariance/invariance.The result has significance in theory formation in science, especiallyin concept and model building. It also raises other questions that gobeyond the aim of this paper: why was he so confident in suchheuristic? Why didn't many other scientists use it? Where did he keep? such a heuristic? Do we have any other examples ofsimilar heuristic search in other scientific problemsolving? (shrink)

There is substantial evidence from many domains that visual representations aid various forms of cognition. We aimed to determine whether visual representations of argument structure enhanced the acquisition and development of critical thinking skills within the context of an introductory philosophy course. We found a significant effect of the use of argument diagrams, and this effect was stable even when multiple plausible correlates were controlled for. These results suggest that natural and relatively minor modifications to standard critical thinking courses could (...) provide substantial increases in student learning and performance. (shrink)

This paper critically examines two arguments against the generic multiverse, both of which are due to W. Hugh Woodin. Versions of the first argument have appeared a number of times in print, while the second argument is relatively novel. We shall investigate these arguments through the lens of two different attitudes one may take toward the methodology and metaphysics of set theory; and we shall observe that the impact of these arguments depends significantly on which of these (...) attitudes is upheld. Our examination of the second argument involves the development of a new model for Steel’s multiverse theory, which is delivered in the Appendix. (shrink)

In the interwar period there was a significant school of thought that repudiated Einstein's theory of relativity on the grounds that it contained elementary inconsistencies. Some of these critics held extreme right-wing and anti-Semitic views, and this has tended to discredit their technical objections to relativity as being scientifically shallow. This paper investigates an alternative possibility: that the critics were right and that the success of Einstein's theory in overcoming them was due to its strengths as an ideology rather than (...) as a science. The clock paradox illustrates how relativity theory does indeed contain inconsistencies that make it scientifically problematic. These same inconsistencies, however, make the theory ideologically powerful. The implications of this argument are examined with respect to Thomas Kuhn and Karl Popper's accounts of the philosophy of science. (shrink)

The degree of doxastic revision required in response to evidence of disagreement is typically thought to be a function of our beliefs about (1) our interlocutor’s familiarity with the relevant evidence and arguments, and their intellectual capacities and virtues, relative to our own, or (2) the expected probability of our interlocutor being correct, conditional on our disagreeing. While these two factors are typically used interchangeably, I show that they have an inverse correlation in cases of disagreement about politically (...) divisive propositions. This presents us with a puzzle about the epistemic impact of disagreement in these cases. The most significant disagreements on (1) are the least significant disagreements on (2), and vice versa. I show that assessing the epistemic status of an interlocutor by reference to either (1) or (2) has uncomfortable consequences in these cases. I then argue that this puzzle cannot be escaped by claiming that we usually have dispute-independent reason to reject the significance of politically charged disagreement altogether. (shrink)

Contemporary biologists are not agreed on the question of whether there are any human races, despite the widespread scientific consensus on the underlying genetics. For most purposes, however, we can reasonably treat this issue as terminological. What most people in most cultures ordinarily believe about the significance of “racial” difference is quite remote, I think, from what the biologists are agreed on. Every reputable biologist will agree that human genetic variability between the populations of Africa or Europe or Asia (...) is not much greater than that within those populations; though how much greater depends, in part, on the measure of genetic variability the biologist chooses. If biologists want to make interracial difference seem relatively large, they can say that “the proportion of genic variation attributable to racial differences is … 9 – 11%.”1 If they want to make it seem small, they can say that, for two people who are both Caucasoid, the chances of difference in genetic constitution at one site on a given chromosome are currently estimated at about 14.3 percent, while for any two people taken at random from the human population, they are estimated at about 14.8 percent. The statistical facts about the distribution of variant characteristics in human populations and subpopulations are the same, whichever way the matter is expressed. Apart from the visible morphological characteristics of skin, hair, and bone, by which we are inclined to assign people to the broadest racial categories—black, white, yellow—there are few genetic characteristics to be found in the population of England that are not found in similar proportions in Zaire or in China; and few too which are found in Zaire but not in similar proportions in China or in England. All this, I repeat, is part of the consensus . A more familiar part of the consensus is that the differences between peoples in language, moral affections, aesthetic attitudes, or political ideology—those differences which most deeply affect us in our dealings with each other—are not biologically determined to any significant degree.[…]In this essay, I want to discuss the way in which W. E. B. Du Bois—who called his life story the “autobiography of a race concept”—came gradually, though never completely, to assimilate the unbiological nature of races. I have made these few prefatory remarks partly because it is my experience that the biological evidence about race is not sufficiently known and appreciated but also because they are important in discussing Du Bois. Throughout his life, Du Bois was concerned not just with the meaning of race but with the truth about it. We are more inclined at present, however, not to express our understanding of the intellectual development of people and cultures as a movement toward the truth; I shall sketch some of the reasons for this at the end of the essay. I will begin, therefore, by saying what I think the rough truth is about race, because, against the stream, I am disposed to argue that this struggle toward the truth is exactly what we find in the life of Du Bois, who can claim, in my view, to have thought longer, more engagedly, and more publicly about race than any other social theorist of our century. 1.

1. Introduction. David Malament has described a natural and satisfying resolution of the traditional problems of Newtonian cosmology—natural in the sense that it effects the escape by altering Newtonian gravitation theory in a way that leaves its observational predictions completely unaffected. I am in full agreement with his approach. There is one part of his account, however, over which Malament has been excessively modest. The resolution requires a modification to Newtonian gravitation theory. Malament presents the modification as so straightforward as (...) to be automatic. This trivializes the crucial postulate, which I shall call the “relativity of acceleration.” It is a significant physical statement in its own right and requires careful justification. Moreover the postulate proved easy to overlook for decades of discussion of the paradox. It really only becomes natural from the perspective of the newer geometric methods Malament exploits. There the postulate has become a commonplace. My purpose here is to develop the following: While Newtonian cosmology can be repaired satisfactorily, in its traditional form it remains deeply troubled. These troubles can be expressed most vividly as the paradoxical contradictions indicated below. They persist in both the integral and differential formulations of Newtonian gravitation theory. Malament's careful geometric treatment is necessarily dense. By taking some liberties with precision, his core result can be expressed in a far simpler form. Attempts to avoid the resolution Malament describes do lead to disaster. Therefore this episode can be inverted and used as the strongest extant argument for the relativity of acceleration in Newtonian gravitation theory. (shrink)

Is it ethical for doctors or courts to prevent patients from making choices that will cause significant harm to themselves in the future? According to an important liberal principle the only justification for infringing the liberty of an individual is to prevent harm to others; harm to the self does not suffice.In this paper, I explore Derek Parfit’s arguments that blur the sharp line between harm to self and others. I analyse cases of treatment refusal by capacitous patients and (...) describe different forms of paternalism arising from a reductionist view of personal identity. I outline an Identity Relative Paternalistic Intervention Principle for determining when we should disallow refusal of treatment where the harm will be accrued by a future self, and consider objections including vagueness and non-identity.Identity relative paternalism does not always justify intervention to prevent harm to future selves. However, there is a stronger ethical case for doing so than is often recognised. (shrink)

Paternalism has attracted new defenders in recent years. Such defenders typically either downplay the normative significance of autonomy or deny that we are sufficiently rational for paternalistic interventions to be objectionable.1 Both of these argumentative strategies constitute challenges to John Stuart Mill’s influential anti-paternalistic ‘harm principle’, which states that coercive interference with the liberty of competent adults is justifiable only if such interference prevents harm to non-consenting third parties (Mill, p. 23).2 In this journal, Wilkinson has provided a novel, (...) provocative defence of paternalism in the medical context—one that (provisionally) accepts rather than challenges Mill’s harm principle.3 Wilkinson’s argument is complex. But he begins with Parfit’s influential account of personal identity.4 According to Parfit, Alice at T1 can be the same person as Alice at T2, but the extent to which Alice at T1 and Alice at T2 are similar depends on the extent to which there are ‘chains’ of strong psychological connections between Alice at T1 and Alice at T2. Strong psychological connections, in turn, are mental states such as intentions or beliefs, or psychological traits. For example, if Alice at T2 remembers very little about herself the day before, and the day before that, all the way to Alice at T1, Alice at T2 has completely different psychological traits than Alice at T1—for example, Alice at T1 was courageous, whereas Alice at T2 is cowardly—then Alice at T1 and Alice at T2 are distinct persons. If the harm principle is correct and Alice is autonomous, it is permissible to interfere with Alice’s liberty only if it prevents harm to some non-consenting third party. But if we accept Parfit’s view on personal identity, then a novel defence of paternalistic intervention emerges: Alice at T2 may well be a distinct person from Alice at T1. So, …. (shrink)

An increasing number of learning goals refer to the acquisition of cognitive skills that can be described as ‘resource-based,’ as they require the availability, coordination, and integration of multiple underlying resources such as skills and knowledge facets. However, research on the support of cognitive skills rarely takes this resource-based nature explicitly into account. This is mirrored in prior research on mathematical argumentation and proof skills: Although repeatedly highlighted as resource-based, for example relying on mathematical topic knowledge, methodological knowledge, mathematical strategic (...) knowledge, and problem-solving skills, little evidence exists on how to support mathematical argumentation and proof skills based on its resources. To address this gap, a quasi-experimental intervention study with undergraduate mathematics students examined the effectiveness of different approaches to support both mathematical argumentation and proof skills and four of its resources. Based on the part-/whole-task debate from instructional design, two approaches were implemented during students’ work on proof construction tasks: (i) asequential approachfocusing and supporting each resource of mathematical argumentation and proof skills sequentially after each other and (ii) aconcurrent approachfocusing and supporting multiple resources concurrently. Empirical analyses show pronounced effects of both approaches regarding the resources underlying mathematical argumentation and proof skills. However, the effects of both approaches are mostly comparable, and only mathematical strategic knowledge benefits significantly more from the concurrent approach. Regarding mathematical argumentation and proof skills, short-term effects of both approaches are at best mixed and show differing effects based on prior attainment, possibly indicating an expertise reversal effect of the relatively short intervention. Data suggests that students with low prior attainment benefited most from the intervention, specifically from the concurrent approach. A supplementary qualitative analysis showcases how supporting multiple resources concurrently alongside mathematical argumentation and proof skills can lead to a synergistic integration of these during proof construction and can be beneficial yet demanding for students. Although results require further empirical underpinning, both approaches appear promising to support the resources underlying mathematical argumentation and proof skills and likely also show positive long-term effects on mathematical argumentation and proof skills, especially for initially weaker students.

While the rule of law is surely a very important good, the familiar discussions found in the literature lead many to conclude that it is either a relatively trivial political ideal, or else a redundant one. What is needed is a new and persuasive defense of the rule of law that properly reflects its great significance for human well being. An important step towards building such an argument is to question a widely-shared but often unnoticed assumption that the rule (...) of law should be understood as a virtue of legal systems. The path is then cleared for a republican argument built on two theses: first, the thought that an ideal society would be one in which no one is the master of anyone else, and second, the thought that our freedom from domination is not natural or pre-institutional.

The theory of social representations must be understood in terms of its proper epistemology so that it can accomplish its full potential in social sciences. This is often difficult to achieve because researchers comprehend it in terms of concepts that are part of static and individualistic Newtonian epistemology rather than in terms of dynamic and relational Einsteinian epistemology. This article considers three signposts that Moscovici identifies and analyses in the theory of relativity, namely the relation between epistemology and science, theory (...) and method, and the argument against the explanation of effects by their causes. The following question is posed: are these signposts also characteristic of the theory of social representations? This question is examined focusing on interactional epistemology, theory and method and the diversity of natural thinking and communication. Moscovici's Psychoanalysis shows that natural thinking appears in a plurality of modes according to the situation in which it takes place and according to social groups towards which it is directed. Natural thinking is controversial and communication-centred. Different professionals, groups and lay people use different kinds of speaking and different communicative genres when they try to resolve “the same” problem. The article suggests that bringing together dialogicality, dialogical linguistics and the theory of social representations may open up new possibilities for theoretical developments in social psychology.

Two main types of philosophical arguments have been given in support of the claim that the citizens of affluent societies have stringent moral duties to aid the global poor: “positive duty” arguments based on the notion of beneficence and “negative duty” arguments based on noninterference. Peter Singer’s positive duty argument (Singer 1972) and Thomas Pogge’s negative duty argument (Pogge 2002) are among the most prominent examples. Philosophers have made speculative claims about the relative effectiveness of these (...) arguments in promoting attitudes and behaviors that could lead to the alleviation of poverty. In this article we present the results of two empirical studies that evaluate these claims, and suggest that both arguments have a modest effect on people’s attitudes and behaviors regarding global poverty. In a replication of the second study, the negative duty argument, in particular, had a statistically significant effect on donations. We discuss the theoretical and practical significance of these results and suggest directions for further research on the role that philosophical arguments can play in engendering concern and action on pressing moral problems.

In the previous article the hermeneutical approach to ethics was outlined. In my presentation, I would like to illustrate further the methodological consequences of this approach by using two points in contemporary applied ethics. The question is: to what extent is the hermeneutical approach casuistically applicable. We start with the presupposition that the hermeneutical approach does not offer answers to the question of current applied ethics — namely, to the question of what is or is not acceptable in a particular (...) problem situation — but rather, intends to clarify our moral, i.e. normative, response to problem situations. It tries to offer a precise articulation of the normative components of a successful moral decision, without presuming its detailed result. Hermeneutical ethics harks back to conceptual possibilities from the philosophical tradition to clarify the fundamental problem posed by current moral casuistry, and this for two reasons. The first is the idea that these traditional concepts are still at work in our experience and speech, such that, in taking up the tradition, the structure of our present experience is highlighted. The second is the idea that our present experience has moved away from this tradition on certain important points, such that a confrontation with these other possibilities can reveal the recent and relative character of what seems self-evident. To start with, I would like to examine the recent discussions in the media on postmenopausal pregnancy, in particular the argument that a pregnancy resulting from a medical treatment of these ‘older mothers’ is unnatural. Appealing to nature has come into discredit in ethics and in public discussions. Yet, I will defend the position that the notion of naturalness is still part of our moral experience. In other words, when we abandon any appeal to the moral significance of our biological nature, we are no longer able to express essential aspects of our moral experience. This, however, does not deny that the moral meaning of nature needs to be rethought and more accurately articulated; the appeal to nature is not obvious. At the end of my presentation, I will show that an appeal to nature also has a role to play in the recent discussions on cloning human embryos. (shrink)

This paper considers clinical psychoanalysis together with developmental psychology (particularly attachment theory), evolution, and neuroscience in the context a Bayesian account of confirmation and disconfrimation. -/- In it I argue that these converging sources of support indicate that the combination of relatively low predictive power and broad explanatory scope that characterise the theories of both Freud and Darwin suggest that Freud's theory, like Darwin's, may strike deeply into natural phenomena. -/- The same argument, however, suggests that conclusive confirmation for Freudian (...) hypotheses, as in the case of Darwin's, will come from outside the original domain of explanation sketched out by Freud. As in Darwin's case conclusive confirmation came from understanding the physical mechanisms or reproduction, in Freud's case it will come from understanding the neural mechanisms that realise the phenomena described in psychoanalysis.

This paper discusses a novel kind of argument for assessing the moral significance of acts of lying and misleading. It is based on considerations about valuable social norms that might be eroded by these actions, because these actions function as signals. Given that social norms can play an important role in supporting morality, individuals have a responsibility to preserve such norms and to prevent ‘cultural slopes’ that erode them. Depending on whether there are norms against lying, misleading, or both, (...) and how likely it is that they might be eroded, these actions can thus have different moral significance. In cases in which the rule ‘do not lie’, as a relatively simple rule, functions as a ‘focal point’, acts of misleading are often morally preferable. In other words, in such cases the possibility of ‘cultural slopes’ can ground a context-dependent slippery slope argument for a moral difference between lying and misleading. (shrink)

In French mechanical treatises of the nineteenth century, Newton’s second law of motion was frequently derived from a relativity principle. The origin of this trend is found in ingenious arguments by Huygens and Laplace, with intermediate contributions by Euler and d’Alembert. The derivations initially relied on Galilean relativity and impulsive forces. After Bélanger’s Cours de mécanique of 1847, they employed continuous forces and a stronger relativity with respect to any commonly impressed motion. The name “principle of relative motions” (...) and the very idea of using this principle as a constructive tool were born in this context. The consequences of Poincaré’s and Einstein’s awareness of this approach are analyzed. Lastly, the legitimacy and significance of a relativity-based derivation of Newton’s second law are briefly discussed in a more philosophical vein. (shrink)

This paper argues for the existence of a certain type of defeater for one’s belief that P—the presence of social incentives not to share evidence against P. Such pressure makes it relatively likely that there is unpossessed evidence that would provide defeaters for P because it makes it likely that the evidence we have is a lopsided subset. This offers, I suggest, a rational reconstruction of a core strand of argument in Mill’s On Liberty. A consequence of the argument is (...) that on morally and politically laden issues in particular, a high degree of doxastic openness might be appropriate. (shrink)

The history of nursing in the home: revealing the significance of place in the expression of moral agency The relationship between place and moral agency in home care nursing is explored in this paper. The notion of place is argued to have relevance to moral agency beyond moral context. This argument is theoretically located in feminist ethics and human geography and is supported through an examination of historical documents (1900–33) that describe the experiences and insights of American home care/private (...) duty nurses or that are related to nursing ethics. Specifically, the role of place in inhibiting and enhancing care, justice, good relationships, and power in the practice of private duty nurses is explored. Several implications for current nursing ethics come out of this analysis. (i) The moral agency of nurses is highly nuanced. It is not only structured by nurses’ relationships to patients and health professionals, i.e. moral context, it is also structured by the place of nursing care. (ii) Place has the potential to limit and enhance the power of nurses. (iii) Some aspects of nursing's conception of the good, such as what constitutes a good nurse–patient relationship, are historically and geographically relative. (shrink)

It has become virtually a matter of dogma—among both philosophers and laypersons—that human lives are more valuable than animal lives. One argument for this claim dominates the philosophical literature and, despite its employment by a host of philosophers, should be found wanting. I try to show that this line of reasoning, as well as one that is less popular but still with significant appeal, are faulty. The errors in each argument seem fatal: the pervasive argument begs the question, and the (...) more selective is, at bottom, unintelligible. We should judge that the lives of humans and animals are equally valuable, an assessment that should be accompanied by major changes in some of our fundamental practices. (shrink)

While the empirical evidence pointing to a gender gap in professional, academic philosophy in the English-speaking world is widely accepted, explanations of this gap are less so. In this paper, we aim to make a modest contribution to the literature on the gender gap in academic philosophy by taking a quantitative, corpus-based empirical approach. Since some philosophers have suggested that it may be the argumentative, “logic-chopping,” and “paradox-mongering” nature of academic philosophy that explains the underrepresentation of women in the discipline, (...) our research questions are the following: Do men and women philosophers make different types of arguments in their published works? If so, which ones and with what frequency? Using data mining and text analysis methods, we study a large corpus of philosophical texts mined from the JSTOR database in order to answer these questions empirically. Using indicator words to classify arguments by type, we search through our corpus to find patterns of argumentation. Overall, the results of our empirical study suggest that women philosophers make deductive, inductive, and abductive arguments in their published works just as much as male philosophers do, with no statistically significant differences in the proportions of those arguments relative to each philosopher’s body of work.

There is substantial evidence from many domains that visual representations aid various forms of cognition. We aimed to determine whether visual representations of argument structure enhanced the acquisition and development of critical thinking skills within the context of an introductory philosophy course. We found a significant effect of the use of argument diagrams, and this effect was stable even when multiple plausible correlates were controlled for. These results suggest that natural⎯and relatively minor⎯modifications to standard critical thinking courses could provide substantial (...) increases in student learning and performance. (shrink)

Interactional competence has attracted increasing attention due to its significance for language users. Previous studies concerning interactional competence mainly focus on synchronous interaction tasks, while the utilization of asynchronous interaction tasks is relatively under-explored despite the importance of asynchronous interaction in real life. Taking the “Responding To Forum Posts” task used in the International Undergraduate English Entrance Examination at Shanghai Jiao Tong University as an example, the study aims to validate the use of asynchronous interaction tasks in the assessment (...) of learner’s interactional competence. 49 students’ performances on the RTFP task were collected through a prototype test of the IUEEE in 2021. The data were analyzed through content analysis, analysis of variance, and ordinal logistic regression. The results showed that the task elicited a wide range of interactional features and test-takers at different proficiency levels differed significantly in the variety of features and the amount of emotion-based interaction. The study also found significant correlations between some of the features and test takers’ overall performance on interactional competence. The study has provided validity evidence for the RTFP task in the assessment of interactional competence and thrown light on the construct of asynchronous written interactional competence. (shrink)

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

The New Rhetoric is founded on the idea that since "argumentation aims at securing the adherence of those to whom it is addressed, it is, in its entirety, relative to the audience to be influenced," says Chaïm Perelman and L. Olbrechts-Tyteca, and they rely, in particular, for their theory of argumentation on the twin concepts of universal and particular audiences: while every argument is directed to a specific individual or group, the orator decides what information and what approaches will (...) achieve the greatest adherence according to an ideal audience. This ideal, Perelman explains, can be embodied, for example, in God, in all reasonable and competent men, in the man deliberating or in an elite." Like particular audiences, then, the universal audience is never fixed or absolute but depends on the orator, the content and goals of the argument, and the particular audience to whom the argument is addressed. These considerations determine what information constitutes facts and reasonableness and thus help to determine the universal audience that, in turn, shapes the orator's approach. The adherence of an audience is also determined by the orator's use of values, a further key concept of the New Rhetoric. Perelman's treatment of value and his view of epideictic rhetoric sets his approach apart from that of the ancients and of Aristotle in particular. Aristotle's division of rhetoric into three genres-forensic, deliberative, and epideictic-is largely motivated by the judgments required for each: forensic or legal arguments require verdicts on past action, deliberative or political rhetoric seeks judgment on future action, and epideictic or ceremonial rhetoric concerns values associated with praise or blame and seeks no specific decisions. For Aristotle, the epideictic genre was of limited importance in the civic realm since it did not concern facts or policies. Perelman, in contrast, believes not only that epideictic rhetoric warrants more attention, but that the values normally limited to that genre are in fact central to all argumentation. Epideictic oratory, Perelman argues, has significant and important argumentation for strengthening the disposition toward action by increasing adherence to the values it lauds." These values are central to the persuasiveness of arguments in all rhetorical genres since the orator always attempts to establish a sense of communion centered around particular values recognized by the audience.".

It is commonplace for undergraduate students to find certain concepts inherent to the disciplines of study troublesome. While some concepts are troublesome simply because they represent new vocabulary for the students, other concepts are troublesome in a more significant sense. Concepts of this kind are troublesome because they highlight an aspect of the deep structure of the discipline, a way of thinking and inquiry, that the students are likely to find strange and even, counter-intuitive, relative to their own pre-existing (...) conceptual frameworks. In this paper, I will argue that the concept of ‘argument’ in the discipline of philosophy, is one such concept. To make the case for this, I will be drawing upon a relatively new and important framework for inquiry into troublesome disciplinary concepts, known as “threshold concept theory” (Meyer and Land 2006, 2008). In addition, I propose to consider the implications, in terms of the design of curriculum and pedagogy for the philosophy classroom, of conceiving argument in threshold concept terms. (shrink)

Approximately 1,500 years ago John Philoponus proposed a simple argument for the existence of God. The argument runs thus: Whatever comes to be has a cause of its coming to be. The universe came to be. Therefore, the universe has a cause of its coming to be. ;Due to the influence of William Lane Craig, this argument and the family of arguments that support it have come to be known as the "kalam" cosmological argument . Craig's account of the (...) KCA incorporates features that serve to distinguish his version as a significant advance. First, conceptual advances in mathematics now permit a clearer presentation of the argument than was previously possible. Second, contemporary Big Bang cosmology confirms the central contention of the KCA, namely, that the past existence of the universe is finite. Reflection upon the implications of using Cantorian transfinite mathematics to model physical processes allowed Craig to develop a distinctively philosophical version of the KCA which is relatively independent of changes in contemporary scientific cosmology. This dissertation is intended as a critical investigation and development of this philosophical strand of the KCA. The literature relating to the KCA has grown however to a significant bulk, and there is now danger of duplication and misassessment due to the plurality of interpretations that the argument has received. Part I of the dissertation addresses this need by laying bare the underlying logical structure of the KCA and by providing a comprehensive "state of the question" . Part II of the dissertation, comprising chapters 3 through 6, focuses upon an important species of objection made to the KCA. This species of objection relies upon thought-experiments designed to show that an actual infinity is possible. I reply: this objection is effectively answered by introducing a metaphysics of substances. In the course of presenting a systematic response I develop an interpretation of the notion of substance that is useful for analytic philosophy, present a general account of the logical requirements of KCA thought-experiments, and outline a theory of logical modality suited to the metaphysical requirements of the KCA.

In a paper from 2005, Gerhard Overland defends the thesis that one's responsibility to render assistance is not affected by having contributed to the situation by causing harm. Overland applies this thesis to the issue of what duties relatively well-off people have in terms of rendering assistance to the global poor and argues for the sub-conclusion that contribution carries little momentum when assessing our duty to assist people in severe need if we can do so at a little cost. In (...) this paper, I discuss Overland's argument in favor of the sub-conclusion and try to show that it is not sound. (shrink)

This book develops a novel argument which combines the Kalam with the Thomistic Cosmological Argument. It approaches an ongoing dispute concerning whether there is a First Cause of time from a radically new point of view, namely by demonstrating that there is such a First Cause without requiring the controversial arguments against concrete infinities and against traversing an actual infinite (although the book presents original defenses of these arguments as well). This book also develops a novel philosophical argument (...) for the Causal Principle, namely that ‘everything that begins to exist has a cause’, and offers a detailed discussion on whether a First Cause of time can be avoided by a causal loop. It also addresses epistemological issues related to the Cosmological Argument which have been relatively neglected by recent publications, and demonstrates (contra Hawking et al) the continual relevance and significance of philosophy for answering ultimate questions. -/- .

Many have expected that understanding the evolution of norms should, in some way, bear on our first-order normative outlook: How norms evolve should shape which norms we accept. But recent philosophy has not done much to shore up this expectation. Most existing discussions of evolution and norms either jump headlong into the is/ought gap or else target meta-ethical issues, such as the objectivity of norms. My aim in this paper is to sketch a different way in which evolutionary considerations can (...) feed into normative thinking—focusing on stability. I will discuss two forms of argument that utilize information about social stability drawn from evolutionary models, and employs it to assess claims in political philosophy. One such argument treats stability as feature of social states that may be taken into account alongside other features. The other uses stability as a constraint on the realization of social ideals, via a version of the ought-implies-can maxim. These forms of argument are not new; indeed they have a history going back at least to early modern philosophy. But their marriage with evolutionary information is relatively recent, has a significantly novel character, and has received little attention in recent moral and political philosophy. (shrink)

G. A. Cohen’s claim that fundamental principles are ‘fact-insensitive’ has not received an especially warm welcome from the philosophical community. While some philosophers have expressed doubts about the plausibility of his claim, others have complained that even if his thesis is true, it is also relatively insignificant. In my paper, I argue that the fact-insensitivity thesis, if true, provides considerable support for value pluralism, and is thus of interest for that reason. Though Cohen himself assumes a plurality of fundamental principles, (...) he never argues that the fact-insensitivity thesis supports this assumption. One of my paper’s aims, then, is to fill an argumentative gap in Cohen’s meta-ethical framework. (shrink)

All change involves temporal variation of properties. There is change in the physical world only if genuine physical magnitudes take on different values at different times. I defend the possibility of change in a general relativistic world against two skeptical arguments recently presented by John Earman. Each argument imposes severe restrictions on what may count as a genuine physical magnitude in general relativity. These restrictions seem justified only as long as one ignores the fact that genuine change in a (...) relativistic world is frame-dependent. I argue on the contrary that there are genuine physical magnitudes whose values typically vary with the time of some frame, and that these include most familiar measurable quantities. Frame-dependent temporal variation in these magnitudes nevertheless supervenes on the unchanging values of more basic physical magnitudes in a general relativistic world. Basic magnitudes include those that realize an observer's occupation of a frame. Change is a significant and observable feature of a general relativistic world only because our situation in such a world naturally picks out a relevant class of frames, even if we lack the descriptive resources to say how they are realized by the values of basic underlying physical magnitudes.

We aim to show from a new perspective that Quine’s ontological relativity, based largely on his so-called “proxy-function argument”, falls short of being a rigorously coherent philosophical conception, as it exhibits significant formal defects. This new perspective enables exposing the shortcomings of Quine's position and suggests a possible reformulation of the original position. Moreover, we argue that his ontological relativity is inconsistent with the empirical data associated with some of our best physical theories, such as quantum mechanics. We refer to (...) fundamental concepts of philosophy and the foundations of mathematics in order to clarify our critique of Quine’s position concerning the relation between formalized theories and both what we can know about the real world and how we come to know it.

The recent debate on whether Confucian Ethics should be viewed as a type of virtue ethics inevitably touches on the issue of the meaning of virtues such as ren ?, yi ?, and li ?. However, the argument would be over-simplified to claim that since Confucianism puts significant weight on virtues then it is virtue ethics. The conclusion would mainly depend on how we understand the key concepts such as ren, yi and the roles they play in the ethical life (...) of humans. Some scholars interpret ren as benevolence, yet others interpret it as empathy. In this paper, I will make a scrutiny of these concepts and their implications. My primary aim is to discern the characteristics of Confucian ethics, rather than to classify it into some categories that are largely constructs of contemporary philosophy. (shrink)

A committee has to address a complex question, the answer to which requires answering several sub-questions. Two different voting procedures can be used. On one procedure, the committee members vote on each sub-question and the voting results then are used as premises for the committee’s conclusion on the main issue. This premise-based procedure can be contrasted with the conclusion-based procedure. On that procedure, the members directly vote on the conclusion, with the vote of each member being guided by her views (...) on the relevant sub-questions. These procedures are by no means equivalent, which has been pointed out in legal theory in connection with jury votes. There may be a majority of voters supporting each premise, but if these majorities do not significantly overlap, there will be a majority against the conclusion. Pettit connects the choice between the two procedures with general political theory, in particular, with the discussion of deliberative democracy. However, the problem we want to examine concerns the relative advantages and disadvantages of the two procedures from the epistemic point of view. In some cases one can assume that the question before the committee has the right answer. In cases like this, is one of the two procedures better when it comes to tracking the truth? As it turns out, the answer to this query is not univocal. On the basis of Condorcet’s jury theorem, we show that the premise-based procedure is clearly superior if the objective is reach truth for the right reasons, i.e. without making any mistakes on the way. However, if the goal instead is to reach truth for whatever reasons, right or wrong, there will be cases in which using the conclusion-based procedure turns out to be more reliable, even though, for the most part, the premise-based procedure will retain its superiority. Our results partly confirm and partly disconfirm the tentative conjectures that have been put forward in Pettit and Rabinowicz. (shrink)
