The modifier effect refers to the fact that the perceived likelihood of a property in a noun category is diminished if the noun is modified. For example, “Pigs live on farms” is rated as more likely than “Dirty pigs live on farms.” The modifier effect has been demonstrated in many studies, but the underlying cognitive mechanisms are still unclear. This paper reports two series of experiments that jointly point to the conclusion that the modifier effect is the result of a (...) superposition of three cognitive mechanisms: (a) probabilistically softened default inheritance, (b) pragmatic implicatures due to Gricean relevance assumptions, and (c) inference based on world knowledge. We present evidence that the pragmatic effects operate largely on an unconscious level and that their influence can be reduced by changing the presentation format of the cognitive task. (shrink)

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main contenders, critically (...) compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

"Most modern philosophers attempt to solve the problem of morality from within the epistemological assumptions that define the dominant cultural perspective of our age. Alan Gewirth's Reason and Morality is a major work in this ongoing enterprise. Gewirth develops, with patience and skill, what he calls a 'modified naturalism' in which morality is derived by logic alone from the concept of action.... I think that the publication of Reason and Morality is a major event in the history of moral philosophy. (...) It develops with great power a new and exciting position in ethical naturalism. No one, regardless of philosophical stance, can read this work without an enlargement of mind. It illuminates morality and agency for all."—E. M. Adams, The Review of Metaphysics "This is a fascinating study of an apparently intractable problem. Gewirth has provided plenty of material for further discussion, and his theory deserves serious consideration. He is always aware of possible rejoinders and argues in a rigorous manner, showing a firm grasp of the current state of moral and political philosophy."—Mind. (shrink)

This study focuses on current jurisprudential debate between the "positivist" views of Herbert Hart and the "rights thesis" of Ronald Dworkin. MacCormick provides a critical analysis of the Dworkin position while also modifying Hart's. It stands firmly on its own as a contribution to an extensive literature.

In this paper, I argue that we can get surprisingly far in vindicating common intuitions about population ethics without assuming that the well-being of those we could create gives us moral reasons for or against creating them. According to the account I sketch, rather than generating procreative reasons, facts about our potential offspring’s well-being serve as normative background conditions—they enable, disable, or modify the strength of independent reasons we might have to procreate. It is unclear whether the (...) account can capture everything many of us want to say about population ethics. But whatever the answer, the point remains that background conditions are a powerful and underappreciated tool in population ethics. (shrink)

There are emotively powerful words that can modify our judgment, arouse our emotions, and influence our decisions. The purpose of this paper is to provide instruments for analyzing the structure of the reasoning underlying the inferences that they trigger, in order to investigate their reasonableness conditions and their persuasive effect. The analysis of the mechanism of persuasion triggered by such words involves the complex systematic relationship between values, decisions, and emotions, and the reasoning mechanisms that have been investigated under the (...) label of “heuristics.” On the one hand, arguing using ethical words is shown to sometimes involve value-based practical reasoning grounded on evaluative classifications stemming from hierarchies of values and maxims of experience. On the other hand, ethical words provide representations bound to the interlocutor’s experiences and judgments, which trigger specific emotions yielding a particular reaction. This chain of judgments and reactions and the potential fallaciousness thereof can be inquired into by examining the relationship between the heuristic processes of reasoning and the more complex argumentative structure that the use of such words involves. The analysis of the 2013 Italian political campaign and the ad hominem arguments used by the political candidates shows the different strategies and counterstrategies for the manipulation of emotions.

One of the main difficulties with contemporary materialism is the risk of epiphenomenalism: if mental properties systematically depend on physical properties, how can they have causal efficiency? Davidson's anomalous monism' only solves this problem through a "feeble" understanding of the individuation of events and with relative imprecision as to the pertinence of causal explanations formulated in psychological terms. Nor do other conceptions of the individuation of events and the causal power of mental states, as that of Kim and of Jackson (...) and Pettit, solve the problem. It will not then be solved by modifying the theory of the individuation of events. (shrink)

This article examines problems that may arise when addressing liability resulting from the genetic modification of microbes, animals, and plants.

The article also examines how concern expressed by society about injuries feared to result from these genetically modified products could have an impact on the way the courts assess (...) reasonable foreseeability in this area.

Philosophers who hold that religious considerations should play some role in public debate over fundamental issues have criticized Rawls’s ideal of public reason for being too restrictive in generally ruling out such considerations. In response, Rawls has modified his ideal so as to explicitly allow a role for religious considerations in public debate (others, such as Robert Audi, have also offered accounts of public reason along similar lines). Nevertheless, some critics of Rawls’s ideal of public reason, such as Nicholas Wolterstorff, (...) remain unsatisfied. In this paper, I will argue that once Rawls’s ideal of public reason is correctly interpreted, it will be possible to reconcile that ideal with much of the role its critics want religion to have in public debate.

This volume, originally published in 1987, is a collection of seven previously published essays, here slightly modified. Six of these were previously published in various journals over the years 1971-1984 and one was presented at a Kierkegaard conference at St. Olaf college in 1985.

We postulate the Testing Principle : that individuals ''act like statisticians'' when they face uncertainty in a decision problem, ranking alternatives to the extent that available evidence allows. The Testing Principle implies that completeness of preferences, rather than the sure-thing principle , is violated in the Ellsberg Paradox. In the experiment, subjects chose between risky and uncertain acts in modified Ellsberg-type urn problems, with sample information about the uncertain urn. Our results show, consistent with the Testing Principle, that the uncertain (...) urn is chosen more often when the sample size is larger, holding constant a measure of ambiguity (proportion of balls of unknown colour in the urn). The Testing Principle rationalises the Ellsberg Paradox. Behaviour consistent with the principle leads to a reduction in Ellsberg-type violations as the statistical quality of sample information is improved, holding ambiguity constant. The Testing Principle also provides a normative rationale for the Ellsberg paradox that is consistent with procedural rationality. (shrink)

A provision of the Hungarian constitution, adopted in 2011, has renamed the state. The name changed from the Republic of Hungary to Hungary, while the form of the state has remained “republic”. The purpose of this study is to explore the meaning, significance, and several consequences of this provision. The analysis consists of three main parts. The first one gives a general overview of the functions of the names of states. It claims that not only names but also changing or (...) modifying names of states—taking place either by name-giving or by shaping convention—can serve certain functions. The second part focuses on the historical and constitutional details of renaming the Hungarian state, and summarizes the legal context that provided the framework for the 2011 renaming. The third part outlines the arguments for the change, takes a look at the official justification and actual reasons, and reveals some of the consequences of the name change in the past decade. The main contention of the paper is that the renaming of the Hungarian state that took place in 2011 lacked any overt and reasonable justification, and is best explained as an expression of anti-republican sentiment, which indicated, and partly paved the way for the transition into a kind of an authoritarian regime. Finally, the study raises a possible interpretation of the renaming of the Hungarian state in 2011, the point of which is that it adumbrated many later changes in public law and political systems.

In previous work, I showed how the “reason model” of precedential constraint could naturally be generalized from the standard setting in which it was first developed to a richer setting in which dimensional information is represented as well. Surprisingly, it then turned out that, in this new dimensional setting, the reason model of constraint collapsed into the “result model,” which supports only a fortiori reasoning. The purpose of this note is to suggest a modification of the reason model of constraint (...) that distinguishes it from the result model even in the dimensional setting. (shrink)

There are emotively powerful words that can modify our judgment, arouse our emotions and influence our decisions. This paper shows how the use of emotive meaning in argumentation can be explained by showing how their logical dimension, which can be analysed using argumentation schemes, combines with heuristic processes triggered by emotions. Arguing with emotive words is shown to use value-based practical reasoning grounded on hierarchies of values and maxims of experience for evaluative classification.

Aims : The Modified Reasons for Smoking Scale (MRSS) is a widely accepted scale that measures psychological functions of smoking. The scale has been translated in Dutch and has been validated, in order to be used in clinical smoking cessation practice in the Dutch-speaking part of Belgium. This study examined the factorial structure, reliability and validity of the scale in a sample of smokers, who are characterized by a high level of dependence and an explicit motivation to stop smoking. (...) Method : The participants were 383 smokers, who volunteered at the stop-smoking clinic of a Belgian university hospital, and completed the translated scale. They were administered the translated MRSS, the Fagerstrom Test for Nicotine Dependence (FTND). Through a clinical interview, smoking behaviour and smoking history was assessed (daily smoking consumption, years smoking, number of quit attempts, weeks stopped, alcohol and coffee consumption, CO level). Exploratory factor analysis was performed. Internal consistency was studied in order to examine the reliability. The concurrent validity was assessed by means of manova, anova and correlation analysis. Results : Factor analysis identified four factors, named stimulation, pleasure of smoking, social smoking and automatism of smoking. Cronbach's alpha ranged from 0.65 (automatism) to 0.72 (stimulation). manova indicated the influence of the variables age, sex, daily consumption and the FTND (the latter two variables showed a dose-dependent association with each subscale). Regression analysis revealed a relationship with dependence indicators, namely: the daily consumption, the number and duration of previous quit attempts, FTND, CO level and daily coffee intake. Conclusions : The Dutch translation of the MRSS identified four factors and revealed acceptable validity and reliability. The adapted version of the translated scale as a component of the psychological assessment procedure in a smoking cessation treatment in Dutch-speaking areas should be implemented. (shrink)

Kearns and Star have previously recommended that we measure the degree to which a reason supports a conclusion, either about how to act or what to believe, as the conditional probability of the conclusion given the reason. I show how to properly formulate this recommendation to allow for dependencies and conditional dependencies among the considerations being aggregated. This formulation allows us to account for how considerations, which do not themselves favour a specific conclusion, can modify the strength of a reason (...) for that conclusion, and thus to explain the intensifiers and attenuators described by Dancy. The formulation also accounts for the workings of partial undercutters in epistemology. I then show how my account avoids the counterexamples that Brunero levied against probability-based theories of the strengths of reasons. My account supports the theory, suggested by Kearns and Star, that the strengths of reasons are measured by conditional probabilities. If my account is successful, then it will count in favour of the idea that the strengths of reasons are measured on the same scale as are conditional probabilities. (shrink)

The present study compares the philosophy of Leibniz with Heidegger’s thought, in particular his analysis of the principium reddendae rationis sufficientis, the so-called principle of reason: nihil est sine ratione. Early on, the author notes that this version of what Leibniz referred to, in 1686, in a letter to Antoine Arnauld as “my great principle” was for Leibniz merely a “vulgar axiom,” the fundamental form of which “[is that] whereby one can always account for why something has happened this way (...) rather than in some other way”. Heidegger, for his part, finds philosophical meat precisely in the modifying phrase “[in] this way rather than in some other way,” not in the traditional “axiom” that “nothing is without a reason”. Although Leibniz does not give the principium in its pure form in the text cited by Cristin, we are to understand that it is a metaphysical principle, not a logical principle. It is not, however, the principle of causality, which demands an answer to the question about why things are, but rather an ontological principle, which shows that and how things are as they are and not otherwise. The foundation of things, which is expressed in Leibniz’s “great principle,” is like the rose spoken of in a line from Johannes Scheffler’s Cherubinischer Wandersmann that Heidegger admired so much: “The rose is without a ‘why’; it blooms because [weil] it blooms”. Like the rose, the nature of the foundation is not gained by asking “Why?” Yet how can that be? What is more fundamental than asking about etiology, reasons, or grounds? In Der Satz vom Grund [The Principle of Ground], a lecture course from 1955/56, Heidegger replies: “The Why [Warum] looks for [sucht] the foundation. The While [Weil] brings about [bringt] the foundation”. Incidentally, when Heidegger makes a noun from the adverb “weil” in this text, he restores the original meaning of the adverb, which is an abbreviated form of “dieweil,” meaning a span of time. In so doing, he points to the temporal nature of the foundation. We can now better understand how, for Heidegger, the principle of the foundation should not be understood as a proposition or utterance, but rather as something like a tempo marking that leads thinking along its path.

The 'no-supervenience' theorem (Reason, 2019; Reason and Shah, 2021) is a proof that no fully self-aware system can entirely supervene on any objectively observable system. I here present a simple, non-technical summary of the proof and demonstrate its implications for four separate theories of consciousness: the 'property dualism' theory of David Chalmers; the 'reflexive monism' of Max Velmans; Galen Strawson's 'realistic monism'; and the 'illusionism' of Keith Frankish. It is shown that all are ruled out in their current form by (...) the no-supervenience theorem, except for Chalmers' theory, which I show requires humans to behave irrationally. (shrink)

A regulative norm for permissible defense distinguishes the conditions under which we will hold defenders to be innocent of any wrongdoing from those in which we hold them responsible for assault or manslaughter. The norm must strike a fair balance between defenders' security, on the one hand, and other agents’ legitimate claim to live without fear of suffering mistaken defensive harm, on the other. Since agents must make defensive decisions under high pressure and on only partial information, they will sometimes (...) make mistakes. We have reason to want a norm that considers a mistake permissible when it was highly likely on the evidence that defense was proportionate and necessary to avert a threat. However, adopting an evidentialist norm under non-ideal conditions is treacherous business. I briefly survey empirical data suggesting that the type and extent of bias prevalent in the US renders a straightforward evidentialist norm unjust, and thus since the legal practice in the US relies on such a norm, we must explore avenues for reform. Preferably this will take the form of adopting a modified evidential norm, and I explore some promising options. If this proves impossible, however, then we have to accept a strict regulative norm (which does not consider any mistakes permissible), as the sole just alternative. (shrink)

As Kant claimed in the Groundwork, and as the idea has been developed by Korsgaard 1997, Bratman 1987, and Broome 2002. This formulation is agnostic on whether reasons for ends derive from our desiring those ends, or from the relation of those ends to things of independent value. However, desire-based theorists may deny, against Hubin 1999, that their theory is a combination of a principle of instrumental transmission and the principle that reasons for ends are provided by desires. (...) Instead, they may say, there is just one principle, a principle of, if you will, instrumental transmutation: if one desires the end, then one has reason to take the means. See the discussion of General Production, in section 8, for a doubt about this. (shrink)

We offer a model of moral reform and regeneration that involves a wrong-doer making two movements: on the one hand, he identifies with himself as the one who did the act, while he also intentionally moves away from that self (or set of desires and intentions) and moves toward a transformed identity. We see this model at work in the formal practice of contrition and reform in Christian and Buddhist rites. This paper is part of a broader project we are (...) undertaking on the philosophy of forgiveness. (shrink)

Rice is a staple food in China, and, thus, its security has drawn much attention. The Chinese government proactively fuels the application of biotechnology in agriculture and food to cope with increasingly severe food security issues. However, most consumers resist the commercialization of genetically modified rice. One of the important reasons is the consumer perception of its various risks. Conversely, trust in the government, scientists, and media can stimulate consumer purchase. On the basis of the dual perspectives of perceived (...) risks and trust, this study establishes a model of purchase intention for GM rice to explore the structural relationship between variables. Perceived risks explore how exclusion can weaken the purchase intention from the consumer perspective; trust examines the benefits that support can provide. Based on the structural equation model, online survey results of 564 consumers in eight provinces and cities are analyzed. The following observations are offered: health risks, moral risks, and purchase intention are negatively correlated; environmental, functional, and economic risks have no significant correlation with purchase intention; and trust and purchase intention have a significant positive correlation.

In this paper, I consider a novel challenge to John Martin Fischer and Mark Ravizza’s reasons-responsiveness theory of moral responsibility. According to their view, agents possess the control necessary for moral responsibility if their actions proceed from a mechanism that is moderately reasons-responsive. I argue that their account of moderate reasons-responsiveness fails to provide necessary and sufficient conditions for moral responsibility since it cannot give an adequate account of the responsibility of individuals with autism spectrum disorder. Empirical (...) evidence suggests that autistic individuals demonstrate impairments in counterfactual thinking, and these impairments, I argue, are such that they cast doubt on Fischer and Ravizza’s construal of moderate reasons-responsiveness. I then argue that modifying the view in order to accommodate individuals with ASD forces them to defend a strong reasons-responsive account despite the fact that they explicitly deny that such an account can adequately characterize what it is to be morally responsible for one’s actions.

It has generally been recognized that while Bruno Latour’s and Martin Heidegger’s respective philosophies of technology converge on key points there is also a significant difference of attitudes towards the themes discussed. To better appreciate the similarities and differences, I suggest that we seek to understand both Latour and Heidegger as philosophers of the event, who seek to rescue the novel emergence of beings from the sedimentation of reductive, explanatory frameworks. I take up this line of thought and compare Latour’s (...) and Heidegger’s theories of things and the types of experiences they presume. Latour’s metaphysics of the actant ensures that no actant’s activity is ever reduced to being the passive effect of another. Yet while the actant can be ‘applied’ to any entity, from a Heideggerian standpoint this strength is precisely its weakness. Latour’s metaphysics provides a horizon of thought that blocks an original experience of things that Heidegger’s thought points towards. By stepping back from the horizonal experience Latour’s metaphysical blueprint for entities imposes, one can enter into an original opening that stems neither from humans nor nonhumans, but an ineradicable mystery at the origin of being. This mystery is nothing more than the inability to give ultimate reasons for the presence of beings. While Latour’s actant as _Ding_ is simply an actant with innumerable relations, Heidegger’s _das Ding_ is the concrete experience of the dissolution of metaphysical reasons, first and last causes. Precisely because Heidegger’s _das Ding_ emerges from a prior mystery that suspends any overarching causal or purposive schema, things can more freely presence from themselves. (shrink)

The following paper is devoted to the discussion of three important and closely interlocked topics in the philosophy of Donald Davidson, the questions: What are reasons? — What are actions? — And: What is the relation between a reason and an action, when the reason explains the action by giving the agent's reason for doing what he did? The last question is actually a quotation; it is the first sentence of Davidson's famous article Actions, Reasons, and Carnes. Although (...) subse-quently modified in various important respects, it still provides the meta-physical groundwork for Davidson's later views on action theory and the philosophy of mind. It is this metaphysical basis that I want to concentrate on. Offhand, Davidson's answers to all the three questions are common in philosophical action theory: Actions are events, reasons are causes of those events, and giving the agent's reason explains an action because it explains the action causally. In what follows, I shall first recapitulate Davidson's reasoning toward the third claim, which I take to be true and to be what Davidson thinks. In discussing a possible objection against this claim I shall then try to show that the second thesis, the thesis that reasons are causes, is neither true nor is it Davidson's opinion. And finally, I want to argue with regard to the first thesis that although Davidson actually holds that actions are events, he should better abandon this position. (shrink)

In this paper, I argue that the ‘modified youngest first’ principle provides a morally appropriate criterion for making decisions regarding the distribution of scarce medical resources, and that it is morally preferable to the simple ‘youngest first’ principle. Based on the complete lives system's goal of maximizing complete lives rather than individual life episodes, I argue that essential to the value we see in complete lives is the first person value attributed by the experiencer of that life. For a life (...) to be ‘complete’ or ‘incomplete,’ the subject of that life must be able to understand the concept of a complete life, to have started goals and projects, and to know what it would be for that life to be complete. As the very young are not able to do this, it can reasonably be said that their characteristically human lives have not yet begun, giving those accepting a complete lives approach good reason to accept the modified youngest first principle over a simple ‘youngest first’ approach.

Conscious macrostates are usually assumed to be emergent from the underlying physical microstates comprising the brain and nervous system of biological organisms. However, a major problem with this assumption is that consciousness is essentially nonmeasurable unlike all other proven emergent properties of physical systems. In an earlier paper, using a no-go theorem, it was shown that conscious states cannot be comprised of processes that are physical in nature (Reason, 2019). Combining this result with another unrelated work on causal emergence in (...) physical systems (Hoel, Albantakis and Tononi, 2013), we show in this paper that conscious macrostates are not emergent from physical systems and they also do not supervene on physical microstates. An important implication of our work is that there must be some form of violation of energy conservation in biological systems that are conscious. (shrink)

BackgroundUse of modified texture diets—thickening of liquids and modifying the texture of foods—in the hope of preventing aspiration, pneumonia and choking, has become central to the current management of dysphagia. The effectiveness of this intervention has been questioned. We examine requirements for a valid informed consent process for this approach and whether the need for informed consent for this treatment is always understood or applied by practitioners.Main textValid informed consent requires provision of accurate and balanced information, and that agreement is (...) given freely by someone who knows they have a choice. Current evidence, including surveys of practitioners and patients in different settings, suggests that practice in this area is often inadequate. This may be due to patients’ communication difficulties but also poor communication—and no real attempt to obtain consent—by practitioners before people are ‘put on’ modified texture diets. Even where discussion occurs, recommendations may be influenced by professional misconceptions about the efficacy of this treatment, which in turn may poison the well for the informed consent process. Patients cannot make appropriate decisions for themselves if the information provided is flawed and unbalanced. The voluntariness of patients’ decisions is also questionable if they are told ‘you must’, when ‘you might consider’ is more appropriate. Where the decision-making capacity of patients is in question, inappropriate judgements and recommendations may be made by substitute decision makers and courts unless based on accurate information.ConclusionResearch is required to examine the informed consent processes in different settings, but there is ample reason to suggest that current practice in this area is suboptimal. Staff need to reflect on their current practice regarding use of modified texture diets with an awareness of the current evidence and through the ‘lens’ of informed consent. Education is required for staff to clarify the importance of, and requirements for, valid informed consent and for decision making that reflects people’s preferences and values. (shrink)

In Responsibility and Control: A Theory of Moral Responsibility John Martin Fischer and Mark Ravizza propose an account of moral responsibility according to which an agent is morally responsible for an action just when that action is the product of her own moderately reasons-responsive mechanism, where reasons-responsiveness is explained in terms of the mechanism’s regular reasons-receptivity and weak reasons-reactivity. In a review of Fischer and Ravizza’s book Mele contends that their weakly reasons-reactivity condition is inadequate, (...) constructing a case in which, according to their theory, an extreme agoraphobic is morally responsible for his staying in his home. In this paper I modify Fischer and Ravizza’s account of moral responsibility in light of Mele’s problematic example, suggesting a refinement of their weakly reasons-reactivity requirement via a distinction between weakly sufficient reasons and strongly sufficient reasons.

This article is based on a Lecture given as part of the Franklin J. Matchette Foundation Lecture Series on Truth at the Catholic University of America, School of Philosophy, in 2002. It explores what theorists in the natural law tradition and modern legal theorists have argued about what makes propositions of morality and law true, focusing on the rubric of "reason" as opposed to "will." It seems probable, and perhaps inevitable, that theorists about the nature of truth in morality must (...) choose between reason and will - that morality, at its core, is either one or the other. What makes law distinctive is that it is, as a practical matter if not by conceptual necessity, a mixture of both. And it is this intertwining of reason and will, of normative system and practical reasoning, which makes assertions about the nature of legal truth, and theories about the nature of law, so difficult. The arguments about truth in law are as much disagreements about what it means to say that a legal proposition is truth as they are about what makes legal propositions true. Are declarations of truth in law statements about legal norms and legal sources, or are they statements about the results of particular disputes or particularized inquiries? There are obvious complilcations in speaking of truth in a context like law, where there is simultaneously an effort to create a coherent normative system and a decision-making procedure that can modify that system in the course of resolving disputes.

This paper shows how two models of precedential constraint can be broadened to include legal information represented through dimensions. I begin by describing a standard representation of legal cases based on boolean factors alone, and then reviewing two models of constraint developed within this standard setting. The first is the “result model”, supporting only a fortiori reasoning. The second is the “reason model”, supporting a richer notion of constraint, since it allows the reasons behind a court’s decisions to be (...) taken into account. I then show how the initial representation can be modified to incorporate dimensional information and how the result and reason models can be adapted to this new dimensional setting. As it turns out, these two models of constraint, which are distinct in the standard setting, coincide once they are transposed to the new dimensional setting, yielding exactly the same patterns of constraint. I therefore explore two ways of refining the reason model of constraint so that, even in the dimensional setting, it can still be separated from the result model. (shrink)

Within-category induction is the projection of a generic property from a class to a subtype of that class. The modifier effect refers to the discovery reported by Connolly et al., that the subtype statement tends to be judged less likely to be true than the original unmodified sentence. The effect was replicated and shown to be moderated by the typicality of the modifier. Likelihood judgements were also found to correlate between modified and unmodified versions of sentences. Experiment 2 elicited justifications, (...) which suggested three types of reason for the effect-pragmatics, knowledge-based reasoning, and uncertainty about attribute inheritance. It is argued that the results provide clear evidence for the default inheritance of prototypical attributes in modified concepts, although a full account of the effect remains to be given. (shrink)

This monograph treats the important topic of the epistemology of diagrams in Euclidean geometry. Norman argues that diagrams play a genuine justificatory role in traditional Euclidean arguments, and he aims to account for these roles from a modified Kantian perspective. Norman considers himself a semi-Kantian in the following broad sense: he believes that Kant was right that ostensive constructions are necessary in order to follow traditional Euclidean proofs, but he wants to avoid appealing to Kantian a priori intuition as the (...) epistemological background for these constructions.Norman's main argument is limited to the thesis that certain Euclidean arguments—in particular, that of Proposition 1.32, the internal-angle-sum theorem—require inferences from diagrams. Interestingly, Norman is not committed to the view that these arguments are proofs. This becomes clear only quite late in the book, when he distinguishes argument from proofs, remarking that the argument he has been focusing on is not rigorous, and so is not a proof . Norman does not, however, explicitly classify all Euclidean arguments as non-proofs. His view is that diagrammatic reasoning can in principle feature in rigorous proofs, but he is not committed to the thesis that any particular argument, Euclidean or otherwise, provides an example of this. Rather than proofs in particular, Norman is more interested in the general issue of justification in mathematics.The argument has three components. First, Norman argues against competing accounts of Euclidean arguments such as empiricism, and ‘Leibnizianism’—the view that diagrams play only a heuristic role. Second, he provides a more direct, or positive, argument that the way we actually follow the standard argument for 1.32 does appeal to the diagram. This is an appeal to the phenomenology of following the argument. Third, he articulates and defends his semi-Kantian position against some objections.The book has a very careful and …. (shrink)
