Some arguments use ‘generic’, or ‘typical’, objects. An explanation for this idea in terms of ‘almost all’ is suggested. The intuition of ‘almost all’ as ‘but for a few exceptions’ is rendered precise by means of ultrafilters. A logical system, with generalized quantifiers for ‘almost all’, is proposed as a basis for generic reasoning. This logic is monotonic, has a simple sound and complete deductive calculus, and is a conservative extension of classical first-order logic, with which it (...) shares several properties. For generic reasoning, generic individuals are introduced and internalized as generic constants, thereby producing conservative extensions where one can reason about generic objects as intended. A many-sorted version of this logic is introduced to handle distinct notions of ‘large’ subsets. Other possible applications for this logic are indicated. (shrink)

This paper offers a new interpretation of Bernard Williams’s infamous claim that the demands of morality violate our integrity. It begins by showing how Williams’s critique targets an underexplored demand for genericity in moral philosophy. It then argues that while this demand is currently a foundational methodological commitment in moral theorizing, it cannot always be met without distorting the very values that theorizing intends to accommodate. Through careful consideration of the importance of practical experience for appreciating the value of ground (...) projects like human relationships, the paper reinterprets the integrity objection as a radical pushback against the way moral philosophy, by and large, represents the phenomenology of personal valuing. This conclusion offers two contributions. First, it reimagines a significant and yet poorly understood implication of Williams’s argument. Second, it raises a new challenge in an old debate: does moral philosophy fairly represent the values it purports to be about? (shrink)

Against recent work by Haslanger and Leslie, I argue that we do not yet have good reason to think that we should single out generics about social groups out as peculiarly destructive, or that we should strive to eradicate them from our usage. Indeed, I suggest they continue to serve a very valuable purpose and we should not rush to condemn them.

This dissertation is intended to provide a formalism for those generics that trigger nonmonotonic inferences. The formalism is to reflect intentionality and exception-tolerating features of generics, and has an emphasis on the axiomatization of generic reasoning that encodes nonmonotonicity. ;A modal conditional approach is taken to formalize the nonmonotonic reasoning in general at the level of object language. A serial of logic systems---MN, NID, NCUM, N STCUM---are constructed in an increasing strength of the characterized nonmonotonic inference relation. (...) In these systems, two binary modal operators ⩾ and > are introduced in their syntax, and a ⊛ function lifted from the traditional * function is deployed in their semantics. These systems are shown to be sound and complete with respect to certain classes of frames defined in the semantics. They are decidable as well. The nonmonotonic inference is argued to be a ternary relation "[phi], Gamma |∼ alpha", and is defined in the system NSTCUM. Many widely discussed nonmonotonic inference patterns such as Defeasible Modus Ponens, Defeasible Transitivity, the Penguin Principle etc. are justified. The specificity rule is proved to be a theorem of the system N STCUM. The impact of negated defaults on an inference is also investigated and accounted for. ;A canonical form to read off generics is proposed: All generic sentences with subject-predicate structure can be re-written into their canonical form S . If S is a plural noun phrase, it can be further refined to be . Normal objects are selected based on the "meaning" of the subject and predicate terms. The second parameter provides an aspect with respect to which certain objects of a kind are considered normal. Due to such a way to select normal objects, the drowning problem is solved. ;The inference behaviors of generics are axiomatized in the system G, which is a quantificational extension of the system NSTCUM. It is proved to be sound and complete with respect to the class of L⩾,G -frames. Those benchmark examples of generic inferences are examined in the system G. (shrink)

In this article a dialectical model for practical reasoning within a community, based on the Generic/Actual Argument Model (GAAM) is advanced and its application to deliberative dialogue discussed. The GAAM, offers a dynamic template for structuring knowledge within a domain of discourse that is connected to and regulated by a community. The paper demonstrates how the community accepted generic argument structure acts to normatively influence both admissible reasoning and the progression of dialectical reasoning between participants. (...) It is further demonstrated that these types of deliberation dialogues supported by the GAAM comply with criteria for normative principles for deliberation, specifically, Alexy’s rules for discourse ethics and Hitchcock’s Principles of Rational Mutual Inquiry. The connection of reasoning to the community in a documented and transparent structure assists in providing best justified reasons, principles of deliberation and ethical discourse which are important advantages for reasoning communities.

We are often justified in acting on the basis of evidential confirmation. I argue that such evidence supports belief in non-quantificational generic generalizations, rather than universally quantified generalizations. I show how this account supports, rather than undermines, a Bayesian account of confirmation. Induction from confirming instances of a generalization to belief in the corresponding generic is part of a reasoning instinct that is typically (but not always) correct, and allows us to approximate the predictions that formal epistemology (...) would make.

When thinking about the notion of essence or of an essential feature, philosophers typically focus on what I will call the notion of objectual essence. The main aim of this paper is to argue that beside this familiar notion stands another one, the notion of generic essence, which contrary to appearance cannot be understood in terms of the familiar notion, and which also fails to be correctly characterized by certain other accounts which naturally come to mind as well. Some (...) of my objections to these accounts are similar to some of Kit Fine’s compelling objections to the standard modal account of (objectual) essence (Fine 1994). In the light of these objections, Fine advances the view that it is metaphysical necessity which has to be understood in terms of essence, rather than the other way around, and takes essence to be unanalyzable. When formulatinghis view, Fine had only objectual essence in mind (or had both concepts in mind, but assumed that the generic is a special case of the objectual), and for that reason, I will argue, his account fails. I will suggest that Fineans should modify their view, and take it that metaphysical necessity is to be understood in terms of the two notions of essence—a view I myself find appealing. Finally, I will end by suggesting a further move which reduces the objectual to the generic, making metaphysical necessity reducible to generic essence alone—a move with which I myself have some sympathy.

Our knowledge about the world is often expressed by generic sentences, yet their meanings are far from clear. This book provides answers to central problems concerning generics: what do they mean? Which factors affect their interpretation? How can one reason with generics? Cohen proposes that the meanings of generics are probability judgments, and shows how this view accounts for many of their puzzling properties, including lawlikeness. Generics are evaluated with respect to alternatives. Cohen argues that alternatives are induced by (...) the kind as well as by the predicated property, and thus provides a uniform account of the varied interpretations of generics. He studies the formal properties of alternatives and provides a compositional account of their derivation by focus and presupposition. Cohen uses his semantics of generics to provide a formal characterization of adequate default reasoning, and proves some desirable results of this formalism. (shrink)

A prevailing thought is that generics have a covert modal operator at logical form. I claim that if this is right, the covert generic modality is a weak necessity modal. In this paper, I pr...

It is widely agreed that generics tolerate exceptions. It turns out, however, that exceptions are tolerated only so long as they do not violate homogeneity: when the exceptions are not concentrated in a salient “chunk” of the domain of the generic. The criterion for salience of a chunk is cognitive: it is dependent on the way in which the domain is mentally represented. Findings of psychological experiments about the ways in which different domains are represented, and the actors affecting (...) such representations, account for judgments of generic sentences, facts which cannot be explained by linguistics alone. The reason for the homogeneity requirement itself is, in turn, also dependent on cognitive considerations. Generics express default rules, and psychological findings have shown that, the more homogeneous the domain, the easier it is for subjects to infer rules about it. Thus, cognitive results form a crucial part of a comprehensive account of the meaning of a linguistic expression. (shrink)

An adequate semantics for generic sentences must stake out positions across a range of contested territory in philosophy and linguistics. For this reason the study of generic sentences is a venue for investigating different frameworks for understanding human rationality as manifested in linguistic phenomena such as quantification, classification of individuals under kinds, defeasible reasoning, and intensionality. Despite the wide variety of semantic theories developed for generic sentences, to date these theories have been almost universally model-theoretic and (...) representational. This essay outlines a range of proof-theoretic analyses for characterizing generics. Particular attention is given to an expressivist proof-theory that can be traced to 1) work on logical syntax that Carnap undertook prior to his turn toward truth-conditional model theory in the late 1930s, and 2) research on sequent calculi and natural deduction systems that originate in work from Gentzen and Prawitz.1.

In this paper, we argue that, although neglected so far, there is a strong link between generics and testimonial injustice. Testimonial injustice is a form of epistemic injustice that “occurs when prejudice causes a hearer to give a deflated level of credibility to a speaker’s word”. Generics are sentences that express generalizations about a category or about its members without specifying what proportion of the category members possess the predicated property. We argue that generics are especially suited to cause testimonial (...) injustice for three reasons. First, generics elicit an “inferential asymmetry” :1452–1482, 2010). That is, generics are accepted even if only a few individuals possess the predicated property but are, nonetheless, taken to refer to almost all the members of the category. This peculiar combination makes generics particularly apt to cause testimonial injustice. High resistance to counter-evidence is a crucial feature of prejudice, the cause of testimonial injustice, and the more highly predictive a generalization the more it will be employed in concrete situations, leading to instances of testimonial injustice. Second, generics seem to play a key role in leading people to develop essentialist beliefs : 273–301, 2010; Rhodes et al. Proc Natl Acad Sci 109: 13526–13531, 2012). Subjects holding such beliefs treat categories as warranting strong generaliations over their members. Therefore, they will be more likely to rely on prejudice while dealing with the category members. Finally, generics are outstandingly common in everyday speech. Hence, their noxious effects are amplified by their diffusion and should not be underestimated. (shrink)

Moral theories often issue general principles that explain our moral judgments in terms of underlying moral considerations. But it is unclear whether the general principles have an explanatory role beyond the underlying moral considerations. In order to avoid the redundancy of their principles, two-level theories issue principles that appear to generalize beyond the considerations that ground them. In doing so, the principles appear to overgeneralize. The problem is conspicuous in the case of contractualism, which proposes that moral principles are grounded (...) in generic reasons that operate in only a subset of the cases covered by the relevant principle. Arguments that motivate the use of generic reasons on the basis of guidance, institutional necessity, or fairness are unsatisfactory. But the generality of moral principles can be justified in terms of the idea of a generic interest, which is an interest that all occupants of a standpoint have in virtue of what occupants of the standpoint as such typically take an interest in. The notion of a generic interest therefore acknowledges a distinction between having and taking an interest, and its use in moral theory is a way of giving expression to the significance of autonomy. This is reminiscent of the idea of a normative power; but the idea of a generic interest is less expensive and makes better sense of the way in which autonomy features in our moral lives. (shrink)

The generic Bohmian trajectories are calculated for an isolated particle in an approximate energy eigenstate, for an arbitrary one-dimensional potential well. It is shown that the necessary and sufficient condition for there to be a negligible probability of the trajectory deviating significantly from the classical trajectory at any stage in the motion is that the state be a narrowly localised wave packet. The properties of the Bohmian trajectories are compared with those in the interpretation recently proposed by García de (...) Polavieja. The reasons why the latter tend to be much more nearly classical are discussed. The implications for other trajectory interpretations are considered. (shrink)

I argue that moral principles involve the same sort of generalization as ordinary yet elusive generic generalizations in natural language such as 'Tigers are striped' or 'Peppers are spicy'. A notable advantage of the generic view is that it simultaneously allows for pessimism and optimism about the role and status of moral principles in our lives. It provides a new perspective on the nature of moral principles on which principles are not apt for determining the moral status of (...) particular actions while they may be apt, and even fundamental, to our acquisition of moral knowledge. A natural consequence of the view is variation amongst moral principles, with some regularly warranting exceptions, and some appearing arguably exceptionless. It is also argued that this generic conception of moral principles has significant advantages, as a normative model of moral reasoning, over the view of moral principles as defaults advanced in recent years.

In his book, "Prejudice", Endre Begby offers a novel and engaging account of the epistemology of prejudice which challenges some of the standard assumptions that have so far guided the recent discussion on the topic. One of Begby's central arguments against the standard view of prejudice, according to which a prejudiced person necessarily displays an epistemically culpable resistance to counterevidence, is that, qua stereotype judgments, prejudices can be flexible and rationally maintained upon encountering many disconfirming instances. By expanding on Begby's (...) analysis, I argue that, given the variety of truth conditions for true generic statements, the generic form of stereotype judgements can sometimes make prejudice extremely resistant to encounters with statistical facts about the distribution of the property among members of a certain group. At the same time, I argue that a more careful consideration of the generic form of stereotypes also allows us to recognize that evidence about how many members of the kind instantiate a property is not the only type of evidence which could disconfirm a prejudice. Evidence of no explanatory relation between a kind and a property should also have a direct effect on a prejudicial belief. For this reason, things may not look as dim for the standard view of prejudice in assessing paradigmatic instances of prejudicial beliefs as irrationally resistant to evidence. (shrink)

I have argued not that economics has no predictive content, but that it is limited, or at least has so far been limited to generic predictions. Now this is an important kind of prediction, and almost certainly a necessary preliminary to specific or quantitative predictions. But if the sketch of an important episode in the twentieth century history of the subject I have given is both correct and representative, then economics seems pretty well stuck at the level of (...) class='Hi'>generic prediction. And at least some influential economists and philosophers of economics seem well satisfied with stopping at the point of generic prediction. Or at least they give no other reason than its power to produce such predictions as a justification for the character of economic theory. But this leads to the question that is the title of my paper, is generic prediction enough? (shrink)

Is it harmful to make generic claims about social groups? Those who say yes cite the reinforcement of oppressive stereotypes and cognitive bias. Those who say no cite the potential of generics to do good, rather than harm, by taking advantage of the same mechanisms that perpetuate the harms. This paper analyzes generic utterances in the context of social justice efforts to weigh in on the debate about whether and how generic utterances contribute to stereotypes and oppression. (...) We need to first pay more attention to what it means to utter generics in social justice contexts. Doing so will allow us to distinguish those generic utterances that are helpful for social justice projects from those that might impede their progress. I argue that there is an important pragmatic sense in which generics can be undermined: especially generics used in service of social justice claims. I then offer an epistemic thesis for why some generics are more susceptible to being undermined by counter-examples than others. I conclude that if we are interested in using generics in the service of social justice, then there is reason to restrict the contexts in which we utter generics. In doing so, I challenge the conventional wisdom that generics are resistant to counterexamples. (shrink)

I argue that the dominant conception of normative reasons in moral philosophy works to exclude certain modes of valuing from fair representation in moral deliberation and justification. I then argue that while reasons are taken to be the center and focus of practical thought, there are a wide and familiar range of activities in everyday life whose full appreciation escapes meaningful formulation in terms of reasons. As a result, the significance of these activities is systematically discounted or ignored by the (...) dominant assumptions about what counts as a reason in the methodology of moral philosophy. I conclude by putting forward my own positive account of practical thinking called loving attention, which contributes to a richer understanding of the elements of practical thought in some familiar cases of valuing, moral concept acquisition, imagination, and attention.

A difficulty for alethic pluralism has been the idea that semantic evaluation of conjunctions whose conjuncts come from discourses with distinct truth properties requires a third notion of truth which applies to both of the original discourses. But this line of reasoning does not entail that there exists a single generic truth property that applies to all statements and all discourses, unless it is supplemented with additional, controversial, premises. So the problem of mixed conjunctions, while highlighting other aspects (...) of alethic pluralism worth investigating further, does not constitute an effective objection to it. (shrink)

Generic language (e.g., “tigers have stripes”) leads children to assume that the referenced category (e.g., tigers) is inductively informative and provides a causal explanation for the behavior of individual members. In two preregistered studies with 4- to 7-year-old children (N = 497), we considered the mechanisms underlying these effects by testing how correcting generics might affect the development of these beliefs about novel social and animal kinds (Study 1) and about gender (Study 2). Correcting generics by narrowing their scope (...) to a single individual limited beliefs that the referenced categories could explain what their members would be like while broadening the scope to a superordinate category (Study 2) uniquely limited endorsement of gender norms. Across both studies, correcting generics did not alter beliefs about feature heritability and had mixed effects on inductive inferences, suggesting that additional mechanisms (e.g., causal reasoning about shared features) contribute to the development of full-blown essentialist beliefs. These results help illuminate the mechanisms by which generics lead children to view categories as having rich inductive and causal potential; in particular, they suggest that children interpret generics as signals that speakers in their community view the referenced categories as meaningful kinds that support generalization. The findings also point the way to concrete suggestions for how adults can effectively correct problematic generics (e.g., gender stereotypes) that children may hear in daily life. (shrink)

The forcing method is a powerful tool to prove the consistency of set-theoretic assertions relative to the consistency of the axioms of set theory. Laver’s theorem and Bukovský’s theorem assert that set-generic extensions of a given ground model constitute a quite reasonable and sufficiently general class of standard models of set-theory.In Sects. 2 and 3 of this note, we give a proof of Bukovsky’s theorem in a modern setting ). In Sect. 4 we check that the multiverse of set- (...) class='Hi'>generic extensions can be treated as a collection of countable transitive models in a conservative extension of ZFC.

Followers of traditional modes of ethical thinking rightly approachpostmodern philosophical methodologies with a certain enigma andsuspicion due to the latter’s tendency to swipe clean basic assumptionswhich had been historically accepted without question. Contemporarytheorists conceptually dig their way into complex labyrinths of noveldefinitions not only to establish the neotericity of their paradigms but also to disengage themselves from the tyranny of dogmatic conclusions that may inhibit their suppositions from being enclosed by established systems of thought. When the Principle of Generic (...) Consistency was introduced by Alan Gewirth in his most popular work Reason and Morality, it spurred numerous reactions, both pros and cons,1 as the principle offered to fulfill the utopian dream of establishing a rational foundation for human rights. The latter part of the book, together with subsequent articles and works, explained in detail how the principle could be applied to the intricacies of applied morality, such as the promotion of man’s well-being, and consequently, the fulfillment of his existence. This paper deals with the same path of Gewirth; only this time, it seeks to construct a rational bridge between a PGC-basedhuman self-fulfillment and the creation of a habitat that embodies hope for political harmony. Moreover, the PGC would not only be construed as the foundation for human rights, but also as a rational trail by which man’s relation with his fellow could serve to develop an intersubjective enhancement of freedom and well-being.

Beyleveld then classifies all the criticisms that Gewirth's argument has received and measures them against his reconstruction of the argument. The overall result is an immensely rich picture of the argument, in which all of its complex issues and key moves are clearly displayed and its validity can finally be discerned. The comprehensiveness of Beyleveld's treatment provides ready access to the entire debate surrounding the foundational argument of Reason and Morality .

This paper presents an attempt to bridge the gap between logical and cognitive treatments of strategic reasoning in games. There have been extensive formal debates about the merits of the principle of backward induction among game theorists and logicians. Experimental economists and psychologists have shown that human subjects, perhaps due to their bounded resources, do not always follow the backward induction strategy, leading to unexpected outcomes. Recently, based on an eye-tracking study, it has turned out that even human subjects (...) who produce the outwardly correct ‘backward induction answer’ use a different internal reasoning strategy to achieve it. The paper presents a formal language to represent different strategies on a finer-grained level than was possible before. The language and its semantics help to precisely distinguish different cognitive reasoning strategies, that can then be tested on the basis of computational cognitive models and experiments with human subjects. The syntactic framework of the formal system provides a generic way of constructing computational cognitive models of the participants of the Marble Drop game. (shrink)

Children approach counterfactual questions about stories with a reasoning strategy that falls short of adults’ Counterfactual Reasoning (CFR). It was dubbed “Basic Conditional Reasoning” (BCR) in Rafetseder et al. (Child Dev 81(1):376–389, 2010). In this paper we provide a characterisation of the differences between BCR and CFR using a distinction between permanent and nonpermanent features of stories and Lewis/Stalnaker counterfactual logic. The critical difference pertains to how consistency between a story and a conditional antecedent incompatible with a (...) nonpermanent feature of the story is achieved. Basic conditional reasoners simply drop all nonpermanent features of the story. Counterfactual reasoners preserve as much of the story as possible while accommodating the antecedent. (shrink)

Over the past few decades, cognitive science has identified several forms of reasoning that make essential use of conceptual knowledge. Despite significant theoretical and empirical progress, there is still no unified framework for understanding how concepts are used in reasoning. This paper argues that the theory of conceptual spaces is capable of filling this gap. Our strategy is to demonstrate how various inference mechanisms which clearly rely on conceptual information—including similarity, typicality, and diagnosticity-based reasoning—can be modeled using (...) principles derived from conceptual spaces. Our first topic analyzes the role of expectations in inductive reasoning and their relation to the structure of our concepts. We examine the relationship between using generic expressions in natural language and common-sense reasoning as a second topic. We propose that the strength of a generic can be described by distances between properties and prototypes in conceptual spaces. Our third topic is category-based induction. We demonstrate that the theory of conceptual spaces can serve as a comprehensive model for this type of reasoning. The final topic is analogy. We review some proposals in this area, present a taxonomy of analogical relations, and show how to model them in terms of distances in conceptual spaces. We also briefly discuss the implications of the model for reasoning with concepts in artificial systems. (shrink)

Many generic sentences express stable inductive generalizations. Stable inductive generalizations are typically true for a causal reason. In this paper we investigate to what extent this is also the case for the generalizations expressed by generic sentences. More in particular, we discuss the possibility that many generic sentences of the form ‘ks have feature e’ are true because kind k have the causal power to ‘produce’ feature e. We will argue that such an analysis is quite close (...) to a probabilistic based analysis of generic sentences according to which ‘relatively many’ ks have feature e, and that, in fact, this latter type of analysis can be ‘grounded’ in terms of causal powers. We will argue, moreover, that the causal power analysis is sometimes preferred to a correlation-based analysis, because it takes the causal structure that gives rise to the probabilistic data into account.

Generic chaplaincy is the result of a devaluing of religious worship and belief to the merely instrumental and experiential. It is an expectable consequence of non-belief in the unique object that would render religious worship intrinsically meaningful and valuable.

In consequence, not all are equally aware of God.

The buck-passing account of values offers an explanation of the close relation of values and reasons for action: of why it is that the question whether something that is of value provides reasons is not ”open.” Being of value simply is, its defenders claim, a property that something has in virtue of its having other reason-providing properties. The generic idea of buck-passing is that the property of being good or being of value does not provide reasons. It is other (...) properties that do. There are, however, at least three versions of the account which differ in their understanding of those “other properties.” The first two versions both assume that non-normative properties provide reasons, the difference being that the second allows that normative properties also provide reasons. Both run into difficulties, which I explain, in trying to defend the claim that non-normative properties provide reasons for action. The third version of the buck-passing account which explains being of value in terms of more specific evaluative properties that are reason-providing remains unpersuasive as well. Once we understand the relation between general and specific properties as a difference in degree, there is no space for a reduction of the one kind of properties to the other. In section II I sketch an alternative account of the relation between reasons and values, which is based on a thesis that I call the Conceptual Link and the claim that values are not just co-extensive with reasons, but explain them.

This paper addresses a recent suggestion that moral particularists can extend their view to countenance default reasons (at a first stab, reasons that are pro tanto unless undermined) by relying on certain background expectations of normality. I first argue that normality must be understood non-extensionally. Thus if default reasons rest on normality claims, those claims won't bestow upon default reasons any definite degree of extensional generality. Their generality depends rather on the contingent distributional aspects of the world, which no theory (...) of reasons should purport to settle. Appeals to default reasons cannot therefore uniquely support particularism. But this argument also implies that if moral generalism entailed that moral reasons by necessity have invariant valence (in the natural extensional sense), it would be a non-starter. Since generalism is not a non-starter, my argument forces us to rethink the parameters of the generalism-particularism debate. Here I propose to clarify the debate by focusing on its modal rather than extensional aspects. In closing, I outline the sort of generalism that I think is motivated by my discussion, and then articulate some worries this view raises about the theoretical usefulness of the label ‘default reason’. -/- [Note: The outline of moral generalism provided in this paper is superseded by those in "Moral Generalism: Enjoy in Moderation" and "A Theory of Hedged Moral Principles".].

In decision making quite often we face permanently changeable and potentially infinite databases when we cannot apply conventional algorithms for choosing a solution. A decision process on infinite databases is called troubleshooting. A decision on these databases is called creative reasoning. One of the first heuristic semi-logical means for creative decision making were proposed in the theory of inventive problem solving by Genrich Altshuller. In this paper, I show that his approach corresponds to the so-called content-generic logic established (...) by Soviet philosophers as an alternative to mathematical logic. The main assumption of content-genetic is that we cannot reduce our thinking to a mathematical combination of signs or to a language as such and our thought is ever cyclic and reflexive so that it contains ever a history.

This article explores Alan Gewirth’s argument for a secular foundation for the idea 2 of human rights as a possible response to Michael J. Perry’s claim “that the idea of 3 human rights is…ineliminably religious.” I examine Gewirth’s reasoning for constructing 3 a theory, namely that existing theories are fundamentally flawed and leave the idea of human rights without a logically consistent foundation, before considering in detail his claims for the Principle of Generic Consistency (PGC). Having looked at (...) his critique of numerous other theories, as well as at his own argument about human action grounding basic rights to freedom and well-being, I then offer a critique of Gewirth’s PGC. Ultimately my conclusion is that Gewrith's 3 theory relies too heavily on the notions, first that we have a meta-desire not to contradict ourselves and, second, that we are unable to find persuasive justifications for our behavior that might allow us to avoid self-contradiction. If one is not troubled by charges of self-contradiction or, as is more often the case, one does not recognize that one’s victim is as much a human being as oneself, Gewirth’s theory 5 V 3 will not seem particularly persuasive. *** DIRECT SUPPORT *** A28BB025 00003.

Inspired by Kit Fine’s theory of arbitrary objects, we explore some ways in which the generic structure of the natural numbers can be presented. Following a suggestion of Saul Kripke’s, we discuss how basic facts and questions about this generic structure can be expressed in the framework of Carnapian quantified modal logic.

At the center of Rawls’s work post-1980 is the question of how legitimate coercive state action is possible in a liberal democracy under conditions of reasonable disagreement. And at the heart of Rawls’s answer to this question is his liberal principle of legitimacy. In this paper I argue that once we attend carefully to the depth and range of reasonable disagreement, Rawls’s liberal principle of legitimacy turns out to be either wildly utopian or simply toothless, depending on how one reads (...) the ideal of reciprocity it is meant to embody. To remedy this defect in Rawls’s theory, I␣undertake to develop the outlines of a democratic conception of legitimacy, drawing first on Rawls’s generic conception of legitimacy in The Law of Peoples and second on a revised understanding of reciprocity between free and equal citizens. On this revised understanding, what free and equal citizens owe one another is not reciprocity in judgment, but reciprocity of interests. (shrink)

Life scientists increasingly rely upon abstraction-based modeling and reasoning strategies for understanding biological phenomena. We introduce the notion of constraint-based reasoning as a fruitful tool for conceptualizing some of these developments. One important role of mathematical abstractions is to impose formal constraints on a search space for possible hypotheses and thereby guide the search for plausible causal models. Formal constraints are, however, not only tools for biological explanations but can be explanatory by virtue of clarifying general dependency-relations and (...) patterning between functions and structures. We describe such situations as constraint-based explanations and argue that these differ from mechanistic strategies in important respects. While mechanistic explanations emphasize change-relating causal features, constraint-based explanations emphasize formal dependencies and generic organizational features that are relatively independent of lower-level changes in causal details. Our distinction between mechanistic and constraint-based explanations is pragmatically motivated by the wish to understand scientific practice. We contend that delineating the affordances and assumptions of different explanatory questions and strategies helps to clarify tensions between diverging scientific practices and the innovative potentials in their combination. Moreover, we show how constraint-based explanation integrates several features shared by otherwise different philosophical accounts of abstract explanatory strategies in biology. (shrink)

Rationality and reasonableness are often sharply distinguished from one another and are even held to be in conflict. On this construal, rationality consists in means-end calculation of the most efficient means to one's ends (which are usually taken to be self-interested), while reasonableness consists in equitableness whereby one respects the rights of other persons as well as oneself. To deal with this conflict, it is noted that both rationality and reasonableness are based on reason, which is analyzed as the power (...) of attaining truth, and especially necessary truth. It is then shown that, by the rationality involved in reason, the moral principle of reasonableness, the Principle of Generic Consistency (PGC), has a stringently rational justification in that to deny or violate it is to incur self-contradiction. Objections are considered bearing on relevance and motivation. It is concluded that, where reasonableness and egoistic rationality conflict, the former is rationally superior. (shrink)

This paper argues that recognition is, fundamentally, a relationship between a person and a reason. The recognizer acts for a reason, in the interpersonal case, only when she takes the recognizee’s rational intentions—intentions whose content is favored by reasons—as reasons. Free agency, on this view, is a rational power to act for reasons: the recognizer’s disposition to take the recognizee’s rational intentions as reasons across relevant possible worlds in which she forms these intentions. On the basis of this generic (...) account of free agency, I argue that free productive agency is a rational power to produce for reasons: the recognizer’s disposition to take the rational productive intentions of the recognizee as reasons across relevant possible worlds in which she forms these intentions. But capitalism makes it impossible to satisfy this requirement, for it subjects the taking of reasons to the realization of profit. So capitalism makes capitalist and worker unfree and the realization of free productive agency impossible. (shrink)

There can be reasons for belief, for action, and for feeling. In each case, knowledge of such reasons requires non-empirical knowledge of some truths about them: these will be truths about what there is reason to believe, to feel, or to do – either outright or on condition of certain facts obtaining. Call these a priori truths about reasons, ‘norms’. Norms are a priori true propositions about reasons.It's an epistemic norm that if something's a good explanation that's a reason to (...) believe it. It's an evaluative norm that if someone's cheated you that's a reason to be annoyed with them. There are many evaluative norms, relating to a variety of feelings. Equally, there may be various epistemic norms, even though in this case they all relate to belief. My concern here, however, is with practical norms: a priori truths about what there is reason to do.I have a suggestion about what fundamental practical norms there are, which I would like to describe and explain. It is that there are just three distinct kinds of practical norm governing what there is reason to do – three categories or generic sources of practical normativity, one may say. I call them the Bridge principle, the principle of Good, and the Demand principle – Bridge, Good and Demand for short. I have said more about them in my book, The Domain of Reasons;1 here my aim is simply to set them out and sketch some questions to which this ‘triplism of practical reason’2 gives rise. In particular, since these norms are about practical reasons, not about morality, a question I'll touch on is how moral obligation comes onto the scene. (shrink)

This book presents adaptive logics as an intuitive and powerful framework for modeling defeasible reasoning. It examines various contexts in which defeasible reasoning is useful and offers a compact introduction into adaptive logics. The author first familiarizes readers with defeasible reasoning, the adaptive logics framework, combinations of adaptive logics, and a range of useful meta-theoretic properties. He then offers a systematic study of adaptive logics based on various applications. The book presents formal models for defeasible reasoning (...) stemming from different contexts, such as default reasoning, argumentation, and normative reasoning. It highlights various meta-theoretic advantages of adaptive logics over other logics or logical frameworks that model defeasible reasoning. In this way the book substantiates the status of adaptive logics as a generic formal framework for defeasible reasoning. (shrink)
