Edinburgh School's theory of natural rationality, enunciated to render symmetrical explanation plausible, thereby providing support for its relativism, is presented and evaluated. I have endeavoured to demonstrate that there are gross misinterpretations of Hesse's theory of science, network model, and her conceptions of classification of objects and of universals; that Edinburgh School's theory of natural rationality suffers from a considerable area of ignorance concerning its foundation. I have further shown that not only the (...) theory is not descriptive of the actuality of people's reasoning, but it in fact is normatively laden. Even if these problems can be overcome, I have shown that it ultimately does not render all beliefs equivalent insofar as rationality status is concerned, and hence symmetrical explanation will still not be possible. Concerning the Edinburgh School's interest theory, I have argued that there are some incoherencies in the proposed positions; and that even if these are rectified the resulting theory leads to grotesque absurdities.

In my paper, I partially defend Philippa Foot’s view in answering the question ‘why be moral?’ In her book, Natural Goodness(2001) and her final paper, “Rationality and Goodness” (2004), Foot proposes two ideas: Ethical Naturalism and, what I call, the ‘Anti-Humean Theory of Practical Rationality’. In answering the question ‘why be moral?’, I argue that we should abandon the former and adopt the latter. In Section I, I discuss Foot’s Anti-Humean Theory of Practical Rationality. (...) In Section II, I examine Foot’s Ethical Naturalism. I argue that it is no longer defensible. In Section III, I examine other possible ways to integrate the categories of practical rationality. One is to take a utilitarian approach and another is to take a Kantian approach. I argue that the latter approach is in harmony with Foot’s Anti-Humean Theory of Practical Rationality. (shrink)

Robert Alexy develops his influential theory of legal reasoning exploring the nature of legal argumentation and its relation to practical reasoning. In doing so he sheds light on fundamental questions of law and rationality, which are as crucial to practising lawyers and law students as they are to scholars of legal theory.

If we suppose that reasonable belief is reasonable not because it has a foundation but because it is self-correcting, and that bodies of reasonable belief are self-correctable in virtue of their web-like internal structure, then it becomes natural to ask for explicit accounts both of self-correction itself, and of the web-like internal structure that makes self-correction possible: The theory of rational belief change. ;In this essay we study qualitative, logical theories of rational belief change, in particular the AGM (...) account, and its offshoot, the theory base account. Throughout, however, we use quantitative, probabilistic models as foils. ;We first undertake a systematic, critical study of the AGM account, focusing especially on its "possible worlds" formulation and on its theory of belief revision. According to the AGM account we can represent AGM revision by simple computations over total preorders of possibilities. We investigate iterated AGM revision from this perspective, and prove that symmetry considerations familiar from social choice theory essentially determine a particular ordering dynamics. These symmetry arguments put an upper bound on the sorts of responsiveness we can expect from the AGM model of rational belief change. The most widely criticized feature of the AGM account is its "recovery" condition on belief contraction. We show how to deflect all existing criticisms to recovery by paying close to attention to exactly which beliefs are given up in a particular case. The principal cost of this strategy is that the AGM account becomes harder to apply and to test. ;Theory base accounts add a layer of syntactically-encoded information to the AGM model. We show that this approach fails comprehensively: that it cannot successfully coordinate the syntactic layer of information with underlying contents or with necessary ordering information, and that it sanctions demonstrably irrational belief changes. Our diagnosis is, in part, that the theory base account conflates two distinct sorts of nonmonotonic belief change. ;Lastly, we summarize our current research into quantitative accounts of rational belief change, focusing on a model that generalizes irreducibly two-place probability, and that has the AGM account as a limiting case.

As moral standards, natural law and the notion of properly functioning human nature have persisted in Western cultures from the dawn of civilization. Medieval Christians developed it in their theologies. However, Enlightenment criticism of medieval thought undermined the credibility of natural law and its authority for modern man. Jacques Maritain developed a rational foundation for natural law and sought to provide objectivity to natural law precepts. His theory also reestablishes the divine authority of natural (...) law for a world without faith. Maritain locates the primary disclosure of natural law in the conscience’s moral reflection in a controversial act of pre-conceptual or non-conceptual knowledge called connatural knowledge. (shrink)

Although rhetoric is not a category of ancient Indian philosophy, this paper argues that Śāntarakṣita and Kamalaśīla, 2 eighth-century Indian Buddhist philosophers, can nonetheless be seen to embrace a rhetorical conception of rationality. That is, while these thinkers are strong proponents of rational analysis and philosophical argumentation as tools for attaining certainty, they also uphold the contingent nature of all such processes. Drawing on the categories of the New Rhetoric, this paper argues that these Buddhist thinkers understand philosophical argumentation (...) to be directed at a universal audience of rational beings, where this universal audience is not an actual audience but a rhetorical one constructed through the author’s particular and historically contingent conception of what counts as rational. A reception theory of rationality is one that holds that the rationality of an argument depends upon its acceptance by a rational audience. When philosophers recognize the historically contingent nature of what counts as rational, they can embrace a reception theory of rationality that neither reduces the rational to mere opinion nor restricts it to a single, absolute, and timeless standard.

Interpreters of Aquinas’s theory of natural law have occasionally argued that the theory has no need for God. Some, such as Anthony Lisska, wish to avoid an interpretation that construes the theory as an instance of theological definism. Instead Lisska sees Aquinas’s ontology of natural kinds as central to the theory. In his zeal to eliminate God from Aquinas’s theory of natural law, Lisska has overlooked two important features of the theory. (...) First, Aquinas states that the desire for God is a primary precept of the natural law and thus constitutes a critical aspect of his ontology. Secondly, Aquinas’s theory of natural law must be seen in the larger context of his theory of participation since he says, “The natural law is the rational creature’s participation in the eternal law.”.

In the theoretical philosophy of Immanuel Kant, the term object has an extensive and far-reaching significance, and it can therefore be understood as a theory of objects. This becomes particularly clear when it is observed that all of his guidelines can be traced to different concepts of objects and their combination. With his concept of the object of experience, he attempts to mediate incompatible aspects in this: in relation to the object of experience, we have apodictic claims but at (...) the same time our knowledge of the object develops and contains the possibility of historical progress. This theory of objects was elaborated by Kant with regard to natural science and the claim of its metaphysical foundation. For this reason, Kant’s concept of object is inherently linked with his concept of science. Astronomy is at the core of his investigation, because it represents a perfect example of a so-called proper and rational natural science. (shrink)

The essays in this volume investigate the norms of reason--the standards which contribute to determining whether beliefs, inferences, and actions are rational.

Current work in the theory of rationality is subject to very diverse influences ranging from experimental and theoretical psychology, through philosophy (...) of logic and language, to metaethics and the theory of practical reasoning; this range is well represented here.

What rational justification is there for conceiving of all living things as possessing inherent worth? In _Respect for Nature_, Paul Taylor draws on biology, moral philosophy, and environmental science to defend a biocentric environmental ethic in which all life has value. Without making claims for the moral rights of plants and animals, he offers a reasoned alternative to the prevailing anthropocentric view--that the natural environment and its wildlife are valued only as objects for human use or enjoyment. _Respect for (...) Nature_ provides both a full account of the biological conditions for life--human or otherwise--and a comprehensive view of the complex relationship between human beings and the whole of nature. This classic book remains a valuable resource for philosophers, biologists, and environmentalists alike--along with all those who care about the future of life on Earth. A new foreword by Dale Jamieson looks at how the original 1986 edition of _Respect for Nature_ has shaped the study of environmental ethics, and shows why the work remains relevant to debates today.

According to a widespread view, Thomas Kuhn’s model of scientific development would relegate rationality to a second plane, openly flirting with irrationalist positions. The intent of this article is to clarify this aspect of his thinking and refute this common interpretation. I begin by analysing the nature of values in Kuhn’s model and how they are connected to rationality. For Kuhn, a theory is chosen rationally when: i) the evaluation is based on values characteristic of science; ii) (...) a theory is considered better the more it manifests these values; and iii) the scientist chooses the best-evaluated theory. The second part of this article deals with the thesis of the variability of values. According to Kuhn, the examples through which epistemic values are presented vary for each person, and for this reason individuals interpret these criteria differently. Consequently, two scientists, using the same values, can come to a rational disagreement over which theory to choose. Finally, I point out the limitations of this notion of rationality for the explanation of consensus formation, and the corresponding demand for a sociological theory that reconnects individual rationality with convergence of opinions.

The increasingly wide spread use of RCM, rational choice modeling, and RCT, rational choice theory, in disciplines like economics, law, ethics, psychology, sociology, political science, management facilitates interdisciplinary exchange. This is a great achievement. Yet it nurtures the hope that a unified account of rational active choice making might arise from ‘reason’ in terms of intuitively appealing axioms. Such ‘rationalist’ characterizations of rational choice neglect real human practices and empirical accounts of those practices. This is theoretically misleading and practically (...) dangerous. Searching for a wide reflective equilibrium, WRE, on RCT in evidence-oriented ways can explicate ‘rational’ without rationalism. (shrink)

[from the publisher's website] Questions about the existence and attributes of God form the subject matter of natural theology, which seeks to gain knowledge of the divine by relying on reason and experience of the world. Arguments in natural theology rely largely on intuitions and inferences that seem natural to us, occurring spontaneously—at the sight of a beautiful landscape, perhaps, or in wonderment at the complexity of the cosmos—even to a nonphilosopher. In this book, Helen De Cruz (...) and Johan De Smedt examine the cognitive origins of arguments in natural theology. They find that although natural theological arguments can be very sophisticated, they are rooted in everyday intuitions about purpose, causation, agency, and morality. Using evidence and theories from disciplines including the cognitive science of religion, evolutionary ethics, evolutionary aesthetics, and the cognitive science of testimony, they show that these intuitions emerge early in development and are a stable part of human cognition. -/- De Cruz and De Smedt analyze the cognitive underpinnings of five well-known arguments for the existence of God: the argument from design, the cosmological argument, the moral argument, the argument from beauty, and the argument from miracles. Finally, they consider whether the cognitive origins of these natural theological arguments should affect their rationality. (shrink)

This essay some first steps toward the naturalization of what I call rational intentionality or alternatively type II intentionality. By rational or type II intentionality, I mean that full combination of rational powers and content-bearing states that is paradigmatically enjoyed by mature intact human beings. The problem I set myself is to determine the extent to which the only currently extant approach to the naturalization of the intentional that has the singular virtue of not being a non-starter can be aggregated (...) up into an account of rational intentionality. I have in mind a broadly defined family of accounts whose main members are the indicator/information-theoretic approach of Dretske (1988), the asymmetric dependence theory of Jerry Fodor (1987, 1990, 1994) and the teleo-semantics of Ruth Millikan (1984, 1993). Somewhat inaccurately, I will call this family of approaches the information-theoretic family. To be sure, there is only a rough family resemblance among the members of the information-theoretic family. Indeed, several intense quarrels divide the members of that family one from another, but the precise outcome of those internecine struggles is not directly relevant to the aims of this essay. ² Taken collectively, the information-theoretic family yields a compelling picture of the place of at least a crude form of intentionality -- what I call frog-like or type I intentionality -- in the natural order. Though frog-like or type I intentionality is, I think, a genuine species of intentionality, it may subsist in the absence of rational powers. It is that species of intentionality enjoyed by irritable creatures who, following Brandom (1994). (shrink)

Some combinations of attitudes--of beliefs, credences, intentions, preferences, hopes, fears, and so on--do not fit together right: they are incoherent. A natural idea is that there are requirements of "structural rationality" that forbid us from being in these incoherent states. Yet a number of surprisingly difficult challenges arise for this idea. These challenges have recently led many philosophers to attempt to minimize or eliminate structural rationality, arguing that it is just a "shadow" of "substantive rationality"--that is, (...) correctly responding to one's reasons. -/- In *Fitting Things Together*, Alex Worsnip pushes back against this trend--defending the view that structural rationality is a genuine kind of rationality, distinct from and irreducible to substantive rationality, and tackling the most important challenges for this view. In so doing, he gives an original positive theory of the nature of coherence and structural rationality that explains how the diverse range of instances of incoherence can be unified under a general account, and how facts about coherence are normatively significant. He also shows how a failure to focus on coherence requirements as a distinctive phenomenon and distinguish them adequately from requirements of substantive rationality has led to confusion and mistakes in several substantive debates in epistemology and ethics. -/- Taken as a whole, Fitting Things Together provides the first sustained defense of the view that structural rationality is a genuine, autonomous, unified, and normatively significant phenomenon.

The question of the rationality of conspiratorial belief ¬divides philosophers into mainly two camps. The particularists believe that each conspiracy theory ought to be examined on its own merits. The generalist, by contrast, argues that there is something inherently suspect about conspiracy theories that makes belief in them irrational. Recent empirical findings indicate that conspiratorial thinking is commonplace among ordinary people, which has naturally shifted attention to the particularists. Yet, even the particularist must agree that not all conspiracy (...) belief is rational, in which case she must explain what separates rational from non-rational conspiratorial thinking. In this paper, I contrast three strategies to this end: 1) the probabilistic objectivist, who assesses the objective probability of conspiracies; 2) the subjectivist, who rather focuses on the perspective of the believer, and typically views the decision to believe in a conspiracy as a problem of decision making under risk. Approaches 1) and 2) rely on assessments of the probability of conspiracy which, I argue, limits their applicability. Instead, I explore 3) viewing the problem facing the potential believer as a decision problem under uncertainty about probabilities. I argue, furthermore, that focusing solely on epistemic utilities fails to do justice to the particular character of conspiracy beliefs, which are not exclusively epistemically motivated, and I investigate the rationality of such beliefs under a number of standard decision rules.

I offer a theory of advice. The theory has two parts: an account of the nature of advice, and an account of the quality of advice. In Sect. 2 I defend this definition: Advice: P advises R to X iff P communicates about X-ing to R in a manner that intentionally presents X-ing as worth reasoning to by R. In Sect. 4, I defend a tripartite account of the quality of advice: the standards relevant to whether advice is (...) good concern rational agency in general, the advisee’s particular situation, and the topic of the advice. These accounts of the nature and quality of advice are superior to extant alternatives on the basis of both descriptive adequacy and absurdity. (shrink)

Environmental pressures are not so urgent anymore, comparing to our ancestors. Nonetheless, the number of decisions that contemporary humans are called to make is very high.

This essay argues that Mark C. Murphy's original contribution to natural law ethics succeeds in finding a way between older metaphysical and newer purely practical approaches in this genre. Murphy's reconstruction of the function argument, critique of subjectivist theories of well-being, and rigorous formulation of a flexible welfarist theory of value deserve careful attention. I defend Kant against Murphy's critique and argue that Murphy faces the problem of showing that all his basic goods are morally inviolable. Although I (...) endorse Murphy's critique of radical virtue ethics, I raise objections to the basic moral norms he derives from his list of goods, and to the analysis of peace of mind and happiness as basic goods.

If evolutionary biologist Massimo Pigliucci didn't exist, it would be necessary to invent him. His Tales of the Rational defines an intellectual space as far removed as hardcore religious fundamentalism from mainstream thinking--but it may be coming closer as scientists and skeptics launch more aggressive attacks on pseudoscience and fuzzy thinking. Pigliucci, a rising star on the evolution-creationism debate circuit, pulls out all the stops in his work, not content merely to defend science against its detractors, but eagerly undermining belief (...) in religion and the existence of any gods at all. Using writing that is strong if rarely eloquent, he defines his terms precisely, makes short work of creationists William Lane Craig and Duane Gish, challenges religious preconceptions, and even ventures to hose down the flames of pseudoscience spouting from chaos theory. Readers with any sympathy for spirituality will run face-first into statements like "I do not see what science has to gain from being reconciled with a system of superstitious beliefs that stands for the exact opposite of free inquiry.".

It is clear that Kant's theory of motivation plays a central role in his ethical theory as a whole. Nevertheless, it has been subjected to many interpretations: (i) the 'orthodox' interpretation, (ii) the 'Aristotelian' or 'Humean' interpretation and (iii) the 'rationalist' interpretation. The first part of the thesis aims to provide an interpretation of Kant's theory of rational agency and motivation. I argue that the 'orthodox' and 'Aristotelian' interpretations should be rejected because they are incompatible with Kant's (...) conception of freedom, defending an account of Kant's position that goes along the lines of the rationalist interpretation. I show that Kant's theory of motivation is committed to a form of cognitivism, that is, the cognitive aspects of a motive are always the active factors in motivation. In Kant's terminology, the motives are provided by the agent's maxims, which express the reasons from which the agent acts. This part of the thesis examines Kant's theory of imperatives and his theory of motivation for cases of permissible, moral and immoral action. I conclude that in Kant's system, three levels of moral assessment can be distinguished: (i) rightness, (ii) moral worth, and (iii) virtue. However, my interest in Kant's theory is not merely exegetical; thus, the second aim of the thesis is to place Kant's position within the context of the following contemporary debates in metaethics: (i) debates about the relation between moral judgement and motivation, and (ii) debates about the nature of reasons for action, arguing that the Kantian position still represents an attractive philosophical view today. In relation to (i), I argue that Kant is committed to a form of motivational internalism, reconstruct Kant's argument for this view and reply to some possible externalist objections. In relation to (ii), I claim that since Kant's conception of reasons, based on the concept of maxims, differs from an internal conception of reasons (i.e., a conception that identifies reasons with the agent's desires), and from an external conception of reasons (i.e., a conception of reasons that identifies reasons with facts of the agent's situation), the term volitionism should be reserved to describe Kant's position.

Debates about the moral and political acceptability of particular sexual practices and new technologies often include appeals to a supposed imperative to follow nature. If nature is understood as the totality of all phenomena or as those things that are not artificial, there is little prospect of developing a successful argument to impugn interference with it or sinning against it. At the same time, there are serious difficulties with approaches that seek to identify "proper" human functioning. An alternative approach is (...) to understand interference with nature as acting in a manner that threatens basic background conditions to human choice. Arguably, the theory of background conditions helps explain much of the hostility to practices and technologies that allegedly sin against nature. The theory does not, however, entail that appeals to nature are relevant or rational. Such appeals should be subjected to sceptical scrutiny. Indeed, the theory suggests that arguments against practices and technologies that can be seen as contrary to nature sometimes exercise a psychological attraction that is disproportional to their actual cogency.

In Mencius' theory of the original goodness in human nature, fate is the original source of xing (nature). Heart is the appearance of nature. There are two aspects to nature and heart: ti (form) and yong (function). From the perspective of form, nature is liangzhi (the goodness in conscience) and liangneng (the inborn ability to be good) in human beings and heart is human's conscience and original heart. From the perspective of function, nature is the four things of benevolence, (...) righteousness, propriety and wisdom, and heart consists in compassion, shame, respect, right and wrong. As the foundation for the theory of the original goodness in human nature, conscience and heart are a combination of human moral instinct, moral rationality and moral volition, whereas moral instinct gradually rises to moral volition and passes through moral rationality. Mencius' theory of the original goodness in human nature is not a theory of future goodness, but a theory of original goodness. /// 在孟子的性骨告中，命是性的本原 心是性的显现。性和心的含义都包括 "体" 和 "用" 两层:从体而言，性是人之所以为人的良知良能，心是人的良心和L'; 从用而 言，性是仁义礼智四端，心是恻隐、羞恶、恭敬、剧阳心。良心司马L作为性都色的立 论基础，是人的道德本能、道德理性和道德意志的集舍，其显现过程勘人道德本能出发 经过道德理性逐渐上升到道德意志的过程。孟子的性骨色不是向善论，而是性本善论。.

Recent obituaries for traditional non-naturalistic approaches to rationality are not just premature but demonstrably self-defeating. One such prominent obituary appears in the writings of W. V. Quine, whose pessimism about traditional epistemology stems from his scientism, the view that the natural sciences have a monopoly on legitimate theoretical explanation. Quine also offers an obituary for the a priori constraints on rationality found in “first philosophy”, resting on his rejection of the “pernicious mentalism” of semantic theories of meaning. (...) Quine’s pronouncements of the death of traditional conceptions of rationality in epistemology and in the theory of meaning are, we contend, but misguided wishes for their death, wishes that face severe problems of self-defeat. In addition, Quine’s naturalistic epistemology is subject to damaging skeptical worries, the force of which one cannot escape by ignoring them. A non-naturalistic approach to rationality is here to stay, whether friends of Quine’s naturalism like it or not. Any sweeping claim that non-naturalistic accounts of rationality are dead will face insurmountable obstacles from unavoidable questions about its own rational justification. Such questions will keep non-naturalistic epistemology and first philosophy alive forever, or at least as long as philosophers endure. (shrink)

In this article I draw on resources from the African philosophical tradition to construct a theory of human rights grounded on dignity that presents a challenge to the globally dominant, autonomy-based approach. Whereas the latter conceives of human rights violations as degradations of our rational nature, the former does so in terms of degradations of our relational nature, specifically, our capacity to be party to harmonious or friendly relationships. Although I have in the past presented the basics of the (...) Afro-relational approach, in this article I defend it from objections and also go on the offensive by arguing that understanding the human rights violations of torture and rape to be (roughly) behavior that treats innocent parties in an extremely discordant or unfriendly way is, if not more plausible than standard Kantian understandings, then at least a promising alternative to them.

Hobbes’s state of nature is often analyzed in two-person two-action non-cooperative games. By definition, this literature only focuses on duels. Yet, if we consider general games, i.e., with more than two agents, analyzing Hobbes’s state of nature in terms of duel is not completely satisfactory, since it is a very specific interpretation of the war of all against all. Therefore, we propose a definition of the state of nature for games with an arbitrary number of players. We show that this (...) definition coincides with the strategy profile considered as the state of nature in two-person games. Furthermore, we study what we call rational states of nature. We show that in rational states of nature, the utility level of any agent is equal to his maximin payoff. We also show that rational states of nature always exist in inessential games. Finally, we prove the existence of states of nature in a class of symmetric games. (shrink)

Cantor’s theory of cardinal numbers offers a way to generalize arithmetic from finite sets to infinite sets using the notion of one-to-one association between two sets. As is well known, all countable infinite sets have the same ‘size’ in this account, namely that of the cardinality of the natural numbers. However, throughout the history of reflections on infinity another powerful intuition has played a major role: if a collectionAis properly included in a collectionBthen the ‘size’ ofAshould be less (...) than the ‘size’ ofB(part–whole principle). This second intuition was not developed mathematically in a satisfactory way until quite recently. In this article I begin by reviewing the contributions of some thinkers who argued in favor of the assignment of different sizes to infinite collections of natural numbers (Thabit ibn Qurra, Grosseteste, Maignan, Bolzano). Then, I review some recent mathematical developments that generalize the part–whole principle to infinite sets in a coherent fashion (Katz, Benci, Di Nasso, Forti). Finally, I show how these new developments are important for a proper evaluation of a number of positions in philosophy of mathematics which argue either for the inevitability of the Cantorian notion of infinite number (Gödel) or for the rational nature of the Cantorian generalization as opposed to that, based on the part–whole principle, envisaged by Bolzano (Kitcher).

The paper first summarizes the author's decision-theoretical model of moral behavior, in order to compare the moral implications of the act-utilitarian and of the rule-utilitarian versions of utilitarian theory. This model is then applied to three voting examples. It is argued that the moral behavior of act-utilitarian individuals will have the nature of a noncooperative game, played in the extensive mode, and involving action-by-action maximization of social utility by each player. In contrast, the moral behavior of rule-utilitarian individuals will (...) have the nature of a cooperative game, played in the normal mode, and involving a firm commitment by each player to a specific moral strategy (viz. to the strategy selected by the rule-utilitarian choice criterion) — even if some individual actions prescribed by this strategy, when considered in isolation, should fail to maximize social utility. The most important advantage that rule utilitarianism as an ethical theory has over act utilitarianism lies in its ability to give full recognition to the moral and social importance of individual rights and personal obligations. It is easy to verify that action-by-action maximization of social utility, as required by act utilitarianism, would destroy these rights and obligations. In contrast, rule utilitarianism can fully recognize the moral validity of these rights and obligations precisely because of its commitment to an overall moral strategy, independent of action-by-action social-utility maximization. The paper ends with a discussion of the voter's paradox problem. The conventional theory of rational behavior cannot avoid the paradoxical conclusion that, in any large electorate, voting is always an irrational activity because one's own individual vote is extremely unlikely to make any difference to the outcome of any election. But it can be shown that, by using the principles of rule-utilitarian theory, this paradox can easily be resolved and that, in actual fact, voting, even in large electorates, may be perfectly rational action. More generally, the example of rule utilitarianism shows what an important role the concept of a rational commitment can play in the analysis of rational behavior. (shrink)

Most contemporary philosophers of action accept Aristotle’s view that actions involve movements generated by an internal cause. This is reflected in the wide support enjoyed by the Causal Theory of Action (CTA), according to which actions are bodily movements caused by mental states. Some critics argue that CTA suffers from the Problem of Disappearing Agents (PDA), the complaint that CTA excludes agents because it reduces them to mere passive arenas in which certain events and processes take place. Extant treatments (...) of PDA, most notably those of Michael Bratman and David Velleman, interpret the problem as a challenge to CTA’s ability to capture the role of rational capacities like deliberation and reflection in the etiology of human action. I argue that PDA admits of another interpretation, one that arises when we appreciate that the exercise of higher rational capacities in action presupposes possession of a prior lower-level capacity for basic self-movement – the power to initiate and control one’s bodily behavior. Bolstering CTA so that it accommodates richer exercises of practical thought – as Bratman and Velleman do – will not resolve PDA unless CTA already captures this basic agential power. Adequately responding to PDA, therefore, requires answering a question unaddressed by current responses: How do bodily movements caused by sub-agential items like mental states count as movements actively performed by the whole agent? I argue that CTA can answer this question by adopting a normative account of the nature of self-moving agents. On this view, self-moving agents are teleologically constituted, meaning (1) their nature and proper function derives from their characteristic ends and aims, and (2) the nature and proper function of their parts depend on these ends and aims. Basic self-movement consists of movements caused by a sub-agential part whose own proper function is to generate behavior that constitutes or contributes to the pursuit of the agent’s overall proper function. After showing how this picture applies to artifactual and collective agents (i.e., robots and teams), I extend the account to organic agents (human beings) by sketching a broadly Aristotelian picture of the nature of living things.

Leibniz and the Rational Order of Nature. New York: Cambridge University Press, 1995. Pp. xiii + 301. Cloth, $54.95. Paper, $18.95.During the twentieth century, scholars of Leibniz have mostly ignored his theology. The tide has recently turned, however, and a few brave souls have begun to disentangle the subtle complications of the relations between Leibniz’s philosophical (...) theology and the rest of his thought. Donald Rutherford is such a brave soul. In his book, he intends to recover “the theodicy as an essential part of Leibniz’s philosophy” (1). To this end, he offers “a comprehensive interpretation of Leibniz’s metaphysical theories—particularly those of his late writings,” and attempts to show “how theodicy [End Page 139] and metaphysics inform each other in his thought” (1). The book has three parts and ten chapters. In the three chapters of Part I, Rutherford “focuses on Leibniz’s theodicy: his vindication of divine justice, the character of the goods that make this the best of all possible worlds, and the special role assigned to rational minds as agents within God’s providential plan for the world” (1). In the three chapters of Part II, Rutherford turns his attention to “Leibniz’s conception of metaphysics as a rational science” and to the notion of substance at its center (2). Finally, in the four chapters of Part III, Rutherford presents an account of Leibniz’s late metaphysics.The structure of Rutherford’s general argument is ingenious. Most fundamentally, he argues that “the guiding force behind” the theodicy is a commitment to reason: “reason as it directs the creative will of God, reason as it is... realized in the intelligible order of the created world, and reason as it helps human beings discern and appreciate that order.” Moreover, “Leibniz’s metaphysical theories are designed to promote the goals of his theodicy” by evidencing as much as possible that rational order (2). Therefore, once we see the metaphysics in light of its theological goal, the close interconnections among its parts will become evident. As Rutherford nicely puts it: “The Leibniz who emerges in this book is one for whom theoretical and practical ends are inextricably linked” (3).In Part I, Rutherford describes the project of the theodicy and, along the way, offers answers to questions which have plagued scholars for decades: What is the relation between variety and simplicity as (apparently conflicting) criteria of worldly goodness? How is the demand for the maximization of perfection related to the (apparently conflicting) commitment to the optimization of the happiness of rational creatures? How can there be different orders and harmonies in one world? Although many of Rutherford’s proposals are both plausible and interesting, they are painted with such broad strokes that they are sometimes difficult to evaluate. Some of the missing details are supplied later in the book, but others are not. For example, a clear picture of the relation between God’s power, goodness, will, and rationality never emerges. In Part II, Rutherford surveys some important texts and topics which concern Leibniz’s methodology, and he presents an intelligent interpretation of Leibniz’s theory of substance. There is much that is interesting here. In Part III, Rutherford is at his best. He ties together many of the separate strands of the late philosophy and tells a plausible story about monads, panorganism, and corporeal substance. This is a genuine achievement and one that will generate a lot of discussion.While I applaud Rutherford’s attempt to construct a coherent account of Leibniz’s philosophy, it is my opinion that he has attached too much importance both to the rational order that is supposed to please the faculty of reason, whether divine or human, and to that faculty itself. According to the Christianized Platonism that Leibniz learned (among many other things) from his teachers in Leipzig, it is the intellect or understanding (intellectus) and not the reason that comes to know the most fundamental truths; and moreover the goodness that created beings (and their interrelations) are supposed to have is based on the fact that they are expressions of God...

Marxian Liberalism is a theory of justice that results from combining the liberal belief that people have a natural right to be free from unwanted coercion, with the Marxian belief that property is coercive. This combination implies that property must be consented to by all people who do or will exist-and thus such consent must be theoretical. Theoretical consent occurs in a Marxian-liberal original position among parties whose knowledge includes Marxian and liberal beliefs. The parties find it rational (...) to consent to a state that protects liberty, and to a system of property governed by the difference principle interpreted according to a moral version of the labor theory of value.

The search for the backbone of the types of rationality inherent in different cultures keeps on to be an open problem, which remains relevant to the need of closer intercultural interaction in the global world. At the same time, the analysis of the logic of language as the basis for the study of rationality types continues to occupy an important place. Meanwhile, the studies of grammatical structures and language models from the point of view of their connection to (...) a certain type of thinking and influence on the method of philosophizing are still quantitatively inferior to the researches of lexical aspects. Expansion of this type of research with the involvement of a diverse cultural material over time will allow us to reach the level of establishing regularities of a more general nature. This article contributes to the development of this issue. The author deals with the approaches to the defnition of the paradigm of Japanese rationality proposed by researchers of grammatical features of the Japanese language, on the one hand, and the “logic of place” concept and the “absolutely contradictory identity” principle of prominent philosopher Nishida Kitaro, on the other hand. A special attention is drawn to the structural similarity of the grammatical form highlighted by linguists, in which the decisive role belongs to the predicate, and to Nishida’s logical model reflecting specifcs of subject-predicate relationship as well as perception of opposition in terms of “contradictory self-identity.” In the conclusion of the article, the author demonstrates the relationship of this model with the certain idea of subject, the type of epistemology overcoming dualism, the processual and cosmocentric comprehension of the world that can be traced in Nishida’s statements.

RESUMEN Se presentan y discuten las teorías de las emociones de W. James y de A. Damasio, enfatizando en la intencionalidad de las emociones y en su vínculo con la racionalidad práctica. Se argumenta que la propuesta de James enfrenta varias dificultades para dar cuenta de ambos aspectos de las emociones, y se muestra cómo la teoría neo-jamesiana de Damasio supera en parte algunas de esas dificultades, pero también da pie a otras objeciones. Se resume la propuesta de Jesse Prinz (...) sobre las emociones como "evaluaciones corporalizadas", que busca incluir el aspecto cognitivo y la naturaleza corporal de las emociones. ABSTRACT The article presents and discusses the theories of emotions of W. James and A. Damasio, with emphasis on the intentionality of emotions and their connection with practical rationality. It argues that James' proposal encounters several difficulties in accounting for both aspects of emotions, and shows how Damasio's neo-Jamesian theory partly overcomes some of those difficulties, while giving rise to other objections. Finally, it summarizes Jesse Prinz's proposal regarding emotions as "embodied appraisals", which seeks to combine the cognitive aspect and the corporeal nature of emotions. (shrink)

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks (...) Nozick. We could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.

The Theory of Knowledge: A Thematic Introduction explains the main ideas and problems of contemporary epistemology while avoiding technical detail. Comprehensive and rich in illustrations and examples, it highlights contemporary debates over the definition, sources, and limits of human knowledge, and covers major topics including the nature of belief, theories of truth, epistemic justification, the Gettier problem, skepticism, and epistemic rationality. Its discussions identify important connections between traditional epistemological questions and cognitive science, the history of science, the sociology (...) of knowledge, and cross-cultural studies. The book culminates with a focus on questions regarding epistemological method and an examination of the roots of contemporary analytic approaches to epistemology. The authors defend a distinctive position regarding epistemological method, called broad explanationism, that incorporates some insights from naturalism in epistemology. The volume is enhanced by a glossary of important epistemological terms and suggestions for further reading. Easily accessible to beginning students in philosophy, The Theory of Knowledge serves as an ideal text for courses in the theory of knowledge and will also appeal to general readers interested in philosophy.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Ministers of the Law: A Natural Law Theory of Legal AuthorityThomas J. BushlackMinisters of the Law: A Natural Law Theory of Legal Authority Jean Porter Grand Rapids, Mich.: Eerdmans, 2010. 368 pp. $30.00Jean Porter’s most recent book is the fruit of her participation with the Emory Center for the Study of Law and Religion since 2005. In this project she undertakes two interrelated tasks. (...) First, she provides compelling reasons for Christian ethicists to engage in questions internal to the discipline of jurisprudence. Second, she demonstrates how a natural law theory grounded in the work of the medieval scholastics can address some of the questions of contemporary jurisprudence. Readers familiar with her previous work will be delighted that she has extended her constructive account of natural law into the realms of jurisprudence and in the process also engages cultural psychology, rhetoric, political philosophy, and international law.Porter begins her engagement with jurisprudence in chapter 1 by noting a paradox recognized by many legal philosophers in the Anglophone world. Legal systems, as they have developed in the West, are characterized by a high degree of autonomy and independence vis-à-vis other social dynamics such as politics or morality. At the same time, however, no legal system can function in complete isolation from considerations of politics and morality. How can we account for the paradoxical autonomy of legal authority? Porter suggests that a scholastic account of natural law can provide a rationally defensible solution to this paradox by developing an account of natural authority (in chapter 2).The force of Porter’s argument rests on the capacity of her account to justify political and legal authority as a natural expression of the authority that any community exercises vis-à-vis its individual members. A community’s authority over its members is justified on the grounds that in prescribing or prohibiting particular acts, it must appeal to claims that could potentially be recognized as justifiable by any rational member of that community. The concept that creates this important hinge between an individual’s good and the good of the community is, of course, the common good. Scholars interested in the concept of the common good will find that her reflection upon it is both rooted deeply in the Christian tradition and applied with fresh insight to the realm of politics (chapter 3) and law (chapter 4). [End Page 210]One potential objection to Porter’s account of natural law could arise in response to her insistence that natural inclinations “underdetermine” the normative content of a natural law morality, leaving her account open to charges of cultural relativism or of being merely descriptive as opposed to normative. However, in this work she is able to turn these criticisms into assets for her account of natural law. She shows (successfully, I believe) how her theory of natural law is able to account for the plurality of moral, political, and legal systems that exist in our world today while still providing normative grounds for critiquing existing social systems. And in chapter 5 she demonstrates how nonderogable, jus cogens principles can be developed from her account of natural law and applied to the field of international law and human rights. In fact, the final section left me hungry for further development of her insights regarding the relationship between natural and international law.This book is written with the same rigorous logic and careful research that has made Porter one of the leading scholars of natural law theory in the field today. As such, this book would be suitable for academics in a wide variety of fields, such as law, political theory, and of course Christian ethics, or for advanced graduate students. It is most certainly a groundbreaking work for demonstrating how a theological account of natural law can engage in constructive dialogue with legal theory and politics at both a theoretical and a practical level.Thomas J.
