Há um vasto número de lamentações a respeito da falta de inteligibilidade da mecânica quântica. Alguns ingredientes da mecânica quântica, contudo, podem possivelmente ser compreendidos pela referência a primeiros princípios, ou seja, a princípios (ou postulados) básicos que, para a intuição, são claros e distintos. Em particular, se nos basearmos em um primeiro princípio denominado princípio da não-singularidade, que pode ser visto como uma hipótese, afirmamos que a mecânica quântica pode ser vista como uma consequência a priori de uma exigência (...) racional. O estatuto do princípio de não-singularidade, óbvio para a maioria dos físicos, pode, contudo, ser criticado, com base em que não há uma intuição universal e que qualquer enunciado é, em princípio, revisável.

There is a huge number of laments concerning the lack of intelligibility of quantum mechanics. Some ingredients of quantum mechanics may however be possibly understood by referring to first principles, that is to say to basic principles which are clear and distinct to the intuition. In particular, if we rely on a first principle called non-singularity principle, which may be viewed as a hypothesis, we claim that quantum mechanics can be viewed as the a priori consequence of a rational (...) demand. The status of the non-singularity principle, obvious to most physicists, may however be criticized, on the basis that there is no universal intuition and that any statement is in principle revisable.

This paper contrasts two views of the necessity to manifest the rational adequacy of argumentation. The view advanced by Ralph Johnson’s program for informal logic will be compared to one based on an account of obligations incurred in speech acts. Both views hold that arguers are commonly obliged to make it apparent that they are offering adequate support for their positions, but they differ in their accounts of the nature and scope of those obligations.

This book demonstrates how an interest in political argument leads naturally to a philosophical way of thinking. It analyses both practising politicans and political theorists and is a much needed introudction to two vitally important, and independent, disciplines.

This paper examines the concept of medical necessity as it relates to mental health care rationing, arguing that the normal functioning model of medical necessity is insufficient because it fails to cohere with an important aim and function of mental health care, which is to provide support for individuals in abusive or otherwise difficult personal relationships.

A common strategy in ethical argumentation tries to derive ethical obligations from the rational necessity of not acting against certain “necessary” conditions for satisfying some good end. This strategy is very often fallacious, and works by equivocating over what counts as a “necessary” condition. Very often, what is counted as a necessary condition is not logically necessary for the end in question, but is at most related to it by affecting the probability of the end’s satisfaction. If other (...) conditions affecting the probability of satisfying this ends are then discounted as merely “instrumental” or “probabilistic”, this strategy has the function of hypocritically privileging some of the arguer’s preferred values over others. We should instead recognize that nearly all conditions affecting the probability of satisfying some good end borrow some value from the value of the end, in proportion to how much they tend to affect its probability of satisfaction. The fallacy tends to support rigid deontological norms; once we abandon it, many arguments against consequentialism are revealed merely as special pleading. Many ethical arguments use this fallacy, but I focus here on its use by Immanuel Kant. (shrink)

The book is an epistemological monograph written from a multidisciplinary perspective. It provides a complex and realistic picture of cognition and rationality, as endowments aimed at making sense and reacting smartly to one's environment, be it epistemic, social or simply ecological. The first part of the book analyzes scientific modeling as products of the biological necessity to cope with the environment and be able to draw as many inferences as possible about it. Moreover, it develops an epistemological framework which (...) will be exploited in both the second part of the book, focusing on social cognition and cognitive niche construction, and the third part, dealing with the apparent irrationality of magical and religious belief. The book also discusses how both social networking and online religion influence cognition, rationality and irrational belief. (shrink)

A confession is in order. As did almost everyone else of a certain persuasion, I recoiled when Sarah Palin invoked the notion of a "death panel" to characterize reform efforts to improve end-of-life counseling. That was wrong and unfair. But I was left uneasy by her phrase. Had I not been one of a handful of bioethicists over the years who had pushed to bring the need for rationing of health care to public attention and proposed ways to carry it (...) out? And was not a common thread running through the latter efforts the likely necessity of some kind of committee or other public mechanism to make the hard decisions? Were we not in other words talking about a "death panel," even if none of us has been so imprudent to .. (shrink)

This paper gives an account of the argument of Schopenhauer's essay On the Freedom of the Human Will, drawing also on his other works. Schopenhauer argues that all human actions are causally necessitated, as are all other events in empirical nature, hence there is no freedom in the sense of liberum arbitrium indifferentiae. However, our sense of responsibility or agency (being the ) is nonetheless unshakeable. To account for this Schopenhauer invokes the Kantian distinction between empirical and intelligible characters. The (...) paper highlights divergences between Schopenhauer and Kant over the intelligible character, which for Schopenhauer can be neither rational nor causal. It raises the questions whether the intelligible character may be redundant to Schopenhauer's position, and whether it can coherently belong to an individual agent, suggesting that for Schopenhauer a more consistent position would have been to deny freedom of will to the individual.

If I understand him correctly, Derek Parfit’s views place us, philosophically speaking, in a very small box. According to Parfit, normativity is an irreducible non-natural property that is independent of the human mind. That is to say, there are normative truths - truths about what we ought to do and to want, or about reasons for doing and wanting things. The truths in question are synthetic a priori truths, and accessible to us only by some sort of rational intuition. (...) Parfit supposes that if we are to preserve the irreducibility of the normative, this is just about all we can say, at least until we bring in some actual intuitions to supply the story with some content.

In this essay, I argue for a revival of Adorno and Horkheimer’s critical philosophy of history on account of the fact that their construction articulates both the necessity of various aspects of our current socio-political conditions given the past tendencies of rationality and domination, and the contingency of the present miseries by problematizing the continuous historical narratives that justify a certain version of the present. After demonstrating that the accomplishment of critical philosophy of history has to be located in (...) the dialectic of the necessary as well as the contingent elements of historical developments, I turn to the Dialectic of Enlightenment as a particular constellation that exemplifies this accomplishment. I show that in this book we find a critical philosophy of history that narrates a story that both makes fascism the necessary corollary and conclusion of instrumental rationality and shows its contingent entanglement with domination. In this way, the initial question of how reason and rationality can lead to domination is now transformed into one that asks how we can we reinterpret and re-animate them such that they are no longer complicit with domination.

For Kant, the human cognitive faculty has two sub-faculties: sensibility and the understanding. Each has pure forms which are necessary to us as humans: space and time for sensibility; the categories for the understanding. But Kant is careful to leave open the possibility of there being creatures like us, with both sensibility and understanding, who nevertheless have different pure forms of sensibility. They would be finite rational beings and discursive cognizers. But they would not be human. And this raises (...) a question about the pure forms of the understanding. Does Kant leave open the possibility of discursive cognizers who have different categories? Even if other discursive cognizers might not sense like us, must they at least think like us? We argue that textual and systematic considerations do not determine the answers to these questions and examine whether Kant thinks that the issue cannot be decided. Consideration of his wider views on the nature and limits of our knowledge of mind shows that Kant could indeed remain neutral on the issue but that the exact form his neutrality can take is subject to unexpected constraints. The result would be an important difference between what Kant says about discursive cognizers with other forms of sensibility and what he is in a position to say about discursive cognizers with other forms of understanding. Kantian humility here takes on a distinctive character. (shrink)

The purpose of this thesis is to demonstrate that metaphysics is a necessary discipline -- necessary in the sense that all areas of philosophy, all areas of science, and in fact any type of rational activity at all would be impossible without a metaphysical background or metaphysical presuppositions. Because of the extremely strong nature of this claim, it is not possible to put forward a very simple argument, although I will attempt to construct one. A crucial issue here is (...) what metaphysics in fact is -- the nature of metaphysics. The conception of metaphysics which I support could be called Aristotelian, as opposed to Kantian: metaphysics is the first philosophy and the basis of all other philosophical and scientific inquiry. I will argue that this is indeed the most plausible conception of metaphysics. (shrink)

A new variety of empirical skeptical moral arguments have been put forward in recent years, drawing on data from neuroscience, social and behavioral psychology, and economics, which strongly suggest that emotions play a central causal role in moral judgment, and that reasoning has at most a limited supplementary causal role in small portion of moral judgments. It follows from these empirical finding, it is argued, that moral judgments and morality more generally cannot be grounded in reason in the right sort (...) of way to be rational. I argue that there are at least three distinct ways of understanding what it means to claim that moral reasoning is necessary to moral judgment. First, that moral reasoning is directly causally necessary to every moral judgment; second that moral reasoning is causally necessary to the ordinary development of the capacity for moral judgment, but is not directly causally implicated in every particular instance of moral judgment; and third that moral reasoning is necessary to a well-ordered capacity for moral judgment. I argue that the empirical data does support the claim that reasoning is not necessary to moral judgment in at least the first sense, perhaps in the second, but not in third, and that this is sufficient to provide for the rationality of moral judgments and morality more generally.

We outline a theory of the cognitive role of belief in absolute necessity that is normative and intended to be metaphysically neutral. We take this theory to be unique in scope since it addresses simultaneously the questions of how such belief is (properly) acquired and of how it is (properly) manifest. The acquisition and manifestation conditions for belief in absolute necessity are given univocally, in terms of complex higher-order attitudes involving two distinct kinds of supposition (A-supposing and C-supposing). (...) It is subsequently argued that the proposed acquisition and manifestation conditions are rationally interdependent, and that such harmony affords explanations of connections between different facets of belief in necessity that otherwise remain mysterious.

‘The several modes of feeling, perception, desire, and will, so far as we are aware of them, are in general called ideas (mental representations) and it may be roughly said that philosophy puts thoughts, categories, or, in more precise language, adequate notions, in the place of generalized images we ordinarily call ideas. Mental impressions such as these may be regarded as the metaphors of thoughts and notions. But to have these figurate conceptions does not imply that we appreciate their intellectual (...) significance, the thoughts and rational notions to which they correspond. Conversely, it is one thing to have thoughts and intelligent notions, and another to know what impressions, perceptions, and feelings correspond to them’.1. (shrink)

In this paper, I explore how the ideal rationality-based account of propositional justification impacts our understanding of the relation between propositional and doxastic justification. The ideal rationality-based account sits uncomfortably with the widely accepted claim that propositional justification is necessary for doxastic justification. In particular, the combination of the necessity claim and the ideal rationality-based account of propositional justification entails that some plausible doxastic attitudes are doxastically unjustified and thereby severs epistemic justification from connections with epistemic responsibility and the (...) competent formation of beliefs. Thus, those who endorse both the necessity claim and the ideal rationality-based account of propositional justification will be forced to give up either their account of propositional justification or the necessity claim. I argue that there is good reason to give up the ideal rationality-based account of propositional justification instead of the necessity claim. This result indicates that an adequate account of propositional justification should be sensitive to the agent’s cognitive capacities. If propositional justification should be understood in this way, then the widely accepted explanation of doxastic justification in terms of propositional justification is not promising either. This is because an agent’s cognitive capacities and limitations play a prominent role in understanding propositional justification. Instead, I argue that, at the explanatory level, propositional justification relies on doxastic justification. (shrink)

BonJour offers two main reasons for supposing that there is such a thing as rational insight into necessity. First, he says there are many examples in which it clearly seems that one has such insight. Second, he argues that any epistemology denying the existence of rational insight into necessity is committed to a narrow skepticism. After commenting about possible frameworks for epistemological justification, I argue against these two claims in reverse order.

Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason (...) to think that our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort. (shrink)

We show that an individual using a choice function is sequentially rational and the decisions he makes are independent of the order of implementation of the rationales if and only if he is rational with the union of the rationales as a base binary relation. When he makes his decisions following a choice correspondence, the sufficiency part of this claim still holds, the necessity part of it does not.

Where Humeans rule out the possibility of material or non-logical necessity, and thus of any associated knowledge a priori, the German legal philosopher Adolf Reinach defends the existence of a wide class of material necessities falling within the domain of what can be known a priori, for example in fields such as color and shape, rational psychology, law and economics. Categories such as promise or claim or obligation are, in Reinach’s view, exist as nodes in a system of (...) necessary relations, so that anyone who has experience of relevant instances of these categories is implicitly aware also of a corresponding family of relations to certain other categories – as for example that every promise implies a mutually correlated claim and obligation. Midway between the two extremes of Hume and Reinach stands Searle, who accepts necessary relations of the mentioned sorts, but sees them as human creations, following from ‘constitutive rules’ analogous to the rules of chess. We seek to demonstrate that Searle does not occupy a stable and acceptable half-way house between Hume and Reinach; that he, too, if he is to do justice to the very constitutive rules which form the center of his approach, must on pain of circularity embrace something like the Reinachian position.

In Ch.10, I apply the previous chapters’ account of modality to the Ontological Argument for the existence of God. I begin the chapter by attempting to develop a sound version of the Ontological Argument based on the work of St. Anselm. I conclude that this argument fails, as does a more recent attempt by Charles Hartshorne and Norman Malcolm. I then give a modal version of the Ontological Argument that is sound and is based on the claim that the property (...) of unsurpassable greatness is possibly exemplified. I grant that this premise is not likely to be accepted by those who do not already hold that the property is actually exemplified, but I argue that it is still rational to accept the premise.

In this paper I will address the question of rationalizing mental causation which is involved in the processes of epistemic justification. The main problem concerning mental causation consists in the apparent incompatibility of the three following claims: (i) the subject's mental states (in particular his belief states) are realized by neural states of the subject's brain; (ii) the justifying character of belief transition consists in the fact that there are certain broadly logical relations between the contents of the relevant beliefs; (...) and (iii) all generations of neural states are, at bottom, governed by the purely physical laws. I try to reconciliate the physical necessity of the neural states generation with the logical rationality of the belief transition. Surprisingly enough, it will turn out that, in a sense, each thinking subject is logically perfect. However, in another sense we are exactly as fallible and irrational as our common-sense tells us.

Kant asserts that the formula of the schools “nihil appetimus, nisi sub ratione boni” is undoubtedly certain when clearly expressed. Conversely, doubt reflects a failure clearly to express it. Once we comprehend the concepts of the formula, of the good and of desire, there is no doubting it. In recent times, the formula has fallen into doubt. If Kant is right, then this shows a lack of clarity with respect to the concepts the formula conjoins. I want to suggest that (...) Kant is right: the formula of the schools is undoubtedly certain. I first explain in Kant’s own terms why there is no such thing as doubting the formula. Then I approach it from a different angle, provided by what I take to be the unclarity that affects current thought on the topic. (shrink)

In the past decade, the meaning of Hegel's idea of a ‘science of logic’ has become a matter of intense philosophical debate. This article examines the two most influential yet opposed contemporary readings of the Science of Logic—often referred to as the ‘metaphysical’ and ‘non-metaphysical’ interpretations. I argue that this debate should be reframed as a contest between logic as ontology (LAO) and logic as metaphysics (LAM). According to Stephen Houlgate's interpretation of logic as ontology, the science of logic is (...) a progressively explicit unfolding of the categories of thought, which is at the same time the process by which being itself determines what it is to be. A second interpretation has been pursued by Sebastian Rödl and Robert Pippin, who read Hegel's logic as metaphysics. On this reading, the science of logic is a progressively coherent unfolding of the categories of thought, which articulate all that it could intelligibly mean to be. This article intervenes in this debate in three key ways. First, I argue that Houlgate's ontological approach undermines his attempt to establish the objective validity of the categories. Second, I show that the LAM emphasis on the crucial idea of apperception enables it to succeed where Houlgate fails by doing justice to the rational necessity with which the Logic unfolds. Third, I argue that, despite this success, the LAM program remains unrealized because of its neglect of Hegel's understanding of cognition as a form of life. While LAM has compellingly unfolded the ‘thought of being’, it has ignored the inverse question of the ‘being of thought’. I attempt to fulfil the LAM program by elaborating Hegel's account of what it means to be a thinker. (shrink)

What is the connection between being in a conscious mental state and believing that you yourself are currently in that state? On the one hand, it is natural to think that this connection is, or involves, a necessary connection of some sort. On the other hand, it is hard to know what the nature of this necessary connection is. For there are plausible arguments according to which this connection is not metaphysically necessary, not rationally necessary, and not merely naturally necessary. (...) If these arguments are correct, and if these options are exhaustive, while there is a necessary connection between a conscious state and the belief that you are in it, there is apparently no necessary connection it could be! This paper sets out this problem—the necessary connection problem, I will call it—and defends and explores a novel proposal about how to solve it. (shrink)

I aim to analyze in this dissertation what a desirable basic institutional structure looks like from the perspective of rationality. While the main topic is thus normative in nature, I start by clarifying in the first part what the notion of rationality exactly entails. I do so by focusing explicitly on the economic conception of rationality, according to which a rational individual is motivated to serve his self-interest on the basis of cost-benefit calculations. Such a Homo Economicus is characterized (...) by his intentional and instrumental actions, his perfectly informed beliefs and his exogenously given and egoistic preferences. In my view, however, this model is inadequate if one aims to understand what it means to be rational. The requirements that actions should be instrumental, beliefs should be based on perfect information and preferences should be exogenously given and egoistic in nature turn out to be overly demanding in this respect. That is why I propose to drop these assumptions in what I label the minimal conception of rationality. Since the latter turns out to be very formal indeed, I propose two further alternatives, which focus not so much on the choice of means to achieve certain goals, as they focus on the choice of these goals themselves. According to the first, broad conception, actions are rational if they are based on good reasons, which are further qualified as well-informed beliefs and autonomous preferences. According to the second, expressive conception, actions, beliefs and preferences are rational if they express the things the individual at hand cares about. The latter requires that individuals can reflect upon and identify with their reasons, which implies a capacity to reflect upon and distance themselves from their own bundle of preferences. In the second part of this dissertation, I try to show the value and limitations of these conceptions by applying them to the context of large-scaled elections. In this respect, it becomes immediately clear that the economic conception fails to explain why quite a lot of people go out and vote. After all, since a single vote has only an infinitesimal impact on the electoral result, it does not enable people to serve their interests or realize their goals. This leads to the so-called voting paradox, according to which no rational individual will decide to vote. The standard solution is to assume that individuals vote because they derive satisfaction from the very act itself. However, this strategy is rather ‘ad hoc’ and does not explain how people vote once they find themselves inside the voting booth. The expressive conception of rationality does better in this respect. It suggests that people vote because they care about democracy in general or about a specific political candidate or ideology. Since they conceive of themselves as being a good citizen, they express this aspect of their identity by going out to vote. In the third part of this dissertation, I analyze more fully the normative implications of the different conceptions of rationality. More specifically, I try to answer the question which basic institutional structure is desirable if one assumes that people are by and large rational. This immediately shows that both the normative issue and the explanatory issue are closely connected. In my view, proposals regarding institutional design and reform should be based on empirically adequate models of individual actions and motivations. This search for a realistic utopia goes against the conventional strategy of most economists. They rely on the Homo Economicus model, even if this fails to explain individual behavior. To explain more fully what the normative implications are of the counterfactual assumption that all people are economically rational, I focus on the work of James Buchanan. In his theory of constitutional choice, he argues in favor of a minimal state whose only task is to make sure that the market functions properly. Buchanan thus favors strict constitutional limitations for governments, which tend to expand beyond legitimate borders as soon as politicians and public servants are allowed to serve their own interests. In my view, however, the abovementioned criticisms of the Homo Economicus model have theoretical as well as normative implications. After all, the empirically supported fact that a majority of individuals does not act in economically rational ways creates more room for legitimate government intervention. Expressively rational citizens will, for example, more easily agree on the necessity and desirability of a collective provision of certain public goods. In addition, expressively rational politicians and public servants can be more easily trusted to serve the public interest rather than their narrowly defined self-interest. As an alternative to Buchanan’s one-sided focus on economic rationality and the market, I focus on the work of Samuel Bowles en Herbert Gintis. More specifically, I explore their work on the phenomenon of strong reciprocity, which refers to the widespread tendency of people to reward prosocial behavior and punish antisocial behavior, even if this is costly for themselves. Since this is clearly economically irrational, Bowles and Gintis propose to complement the Homo Economicus model with the Homo Reciprocans model. This model, which comes close to the expressive conception of rationality, is able to incorporate the insight that social norms surrounding reciprocity, cooperation and fairness are crucial in regulating interactions. At the normative level, Bowles and Gintis stress that such norms often lead to socially desirable outcomes, since they enable people to live in harmony without relying on coercive and costly government interventions. This suggests that the debate between proponents of the market on the one hand and the state on the other hand neglects the importance of communities where people spontaneously interact on the basis of generally prosocial norms. As such, the insights of Bowles and Gintis lead to a defense of a basic institutional structure in which markets, states and communities mutually complement and reinforce each other. They also justify a general optimism as regards to the capacity and motivation of people to try and improve the rules and institutions that govern their everyday lives. (shrink)

This book is a supplement to the author's earlier New Hegelian Essays. It continues the project of presenting the narrative(s) of religion as intelligible metaphysics, "interpreting spiritual things spiritually", as St. Paul says. After an introductory recall of the unreality of the phenomenal individual except insofar as viewed as "in" God, the Absolute, so that all depend upon all, the first subject to be considered is faith itself, too often seen as the polar and hence negative opposite of reason. After (...) this, we plunge straight for the hidden philosophical implications of the Trinity, leading on to a rational viewing of the doctrines of Creation and Incarnation, actually essentially connected. A false view of Creation, as, consequently, of divine transcendence, is here corrected. God has no otherness with which he is not at the same time united and hence identified and this is the very opposite of pantheism, is acosmism rather, God being "all in all". Regarding Incarnation, its full humanistic implications, in a context of Absolute Idealism as the philosophical and true view, are here teased out. Finally, we move to a consideration of "practical reason", virtues, ethical imperatives, their true character and import. The book concludes with some consideration of the eventual role of such philosophy as holding together a great contemporary political project, the European Union. (shrink)

Discussion of the relationship between chance and necessity in the West goes back at least to Democritus in the fifth century BCE, and was highlighted again in the twentieth century by Jacques Monod in Chance and Necessity. Monod contrasted “teleonomic‘ biological evolution with “teleologic‘ Biblical theology. This article uses that distinction in examining Zhu Xi’s concepts of Heaven and tradition. The result sheds light on the unique combination of rationality and transcendence in Neo-Confucian thought.

This paper extends well-established arguments for the liberal potential of vocational education by advocating for the _necessity_ of craft learning in a liberal education curriculum. The case for the necessity of craft learning in liberal education is established in two parts, the first looking toward Aristotle and the second toward Heidegger. First, ideas from Aristotle are employed to articulate a vision of liberal education as that which supports the performance of our characteristic human activity. The paper then splits with (...) Aristotle to suggest that such activity is not defined by rational contemplation, but rather by the circumspective engagement with materials through which our being-in-the-world becomes apparent to us. If, as Heidegger suggests, these practical engagements demonstrate our most fundamental mode of encountering the world and one another, then any liberal education focused on the fulfillment of our potential for understanding must include some craft learning by necessity.

David Gauthier tries to defend morality by showing that rational agents would choose to adopt a fundamental choice disposition that permits them to cooperate in prisoner's dilemmas. In this paper, I argue that Gauthier, rather than trying to work out a prudential justification for his favored choice disposition, should opt for a transcendental justification. I argue that the disposition in question is the product of socialization, not rational choice. However, only agents who are socialized in such a way (...) that they acquire a disposition of this type could acquire the capacity to use language. Given the internal connection between language and thought, this means that no agent endowed with such a disposition could rationally choose to adopt another. Thus rational reflection by moral agents upon their own fundamental choice disposition will have no tendency to destabilize it. (shrink)

This article is about conditionalized modal statements whose antecedents concern a preferential attitude of an agent. The focus is on anankastic conditionals or, as they are known in the philosophical literature, hypothetical imperatives. We present a linguistically-motivated analysis of anankastic and related conditionals and use it to address challenges for semantic theories of natural language conditionals motivated by certain philosophical concerns about practical reasoning and the requirements of rationality.

Is contemporary continental philosophy making a break with Kant? The structures of knowledge, taken for granted since Kants Critique of Pure Reason, are now being called into question: the finitude of the subject, the phenomenal given, a priori synthesis. Relinquish the transcendental: such is the imperative of postcritical thinking in the 21st century. Questions that we no longer thought it possible to ask now reemerge with renewed vigor: can Kant really maintain the difference between a priori and innate? Can he (...) deduce, rather than impose, the categories, or justify the necessity of nature? Recent research into brain development aggravates these suspicions, which measure transcendental idealism against the thesis of a biological origin for cognitive processes. In her important new book Catherine Malabou lays out Kants response to his posterity. True to its subject, the book evolves as an epigenesis – the differentiated growth of the embryo – for, as those who know how to read critical philosophy affirm, this is the very life of the transcendental and contains the promise of its transformation.

This article offers an explanation and analysis of Kant’s philosophy of religion. It starts with Kant’s criticisms of the ontological, cosmological, and physico-teleological arguments for the existence of God from the ’Critique of Pure Reason’. It then explains Kant’s moral arguments in the ’Critique of Practical Reason’ for the existence and nature of God and for humans’ personal immorality. Finally, it lays out the argument for the necessity of grace from Kant’s ’Religion within the Boundaries of Mere Reaso.'.

This paper contrasts a picoeconomic approach to theexplanation of akrasia with Davidson's divided-mind approach and defends theformer in a wider context. The distinctive merits of a picoeconomic model of mindlie in the following aspects: First, it relies on a scientifically well-groundeddiscovery about motivational dynamics of animals for its explanation of preference change,which elucidates or materializes some philosophers' speculations both about thepossible mismatch between valuation and motivation and about the relevance of temporalfactors to akrasia. Second, it grounds the necessity of (...) endogenous higher-order constraints,expressible in forms of judgment, in an intrapersonal dynamic process of interactivefirst-order temporary preferences. Thus the motivational basis for the normativeconstruction of the rationality of `best judgment' can also be illuminated with this model. (shrink)

How should autonomous vehicles be programmed to behave in the event of an unavoidable accident in which the only choice open is one between causing different damages or losses to different objects or persons? This paper addresses this ethical question starting from the normative principles elaborated in the law to regulate difficult choices in other emergency scenarios. In particular, the paper offers a rational reconstruction of some major principles and norms embedded in the Anglo-American jurisprudence and case law on (...) the “doctrine of necessity”; and assesses which, if any, of these principles and norms can be utilized to find reasonable guidelines for solving the ethical issue of the regulation of the programming of autonomous vehicles in emergency situations. The paper covers the following topics: the distinction between “justification” and “excuse”, the legal prohibition of intentional killing outside self-defence, the incommensurability of goods, and the legal constrains to the use of lethal force set by normative positions: obligations, responsibility, rights, and authority. For each of these principles and constrains the possible application to the programming of autonomous vehicles is discussed. Based on the analysis, some practical suggestions are offered. (shrink)

Chance and necessity are mainstays of explanation in current biology, dominated by the neo-Darwinian outlook, a blend of the theory of evolution by natural selection with the basic tenets of population genetics. In such a framework the form of living organisms is somehow a side effect of highly contingent, historical accidents. Thus, at a difference of other sciences, biology apparently lacks theoretical principles that in a law-like fashion may explain the emergence and persistence of the characteristic forms of living (...) organisms that paradoxically, given the current importance attributed to chance, can be grouped into organized structural typologies. Nevertheless, the present essay shows that since its origins in Aristotelian natural history, biology aimed at achieving rational, non-accidental, explanations for the wide variety of living forms endowed with characteristic behaviors that constitute the landscape of biological species.

This article suggests an evaluation of the way by which European Culture understands the idea of rationality of the world. We pursue the consequences of the fact that in this cultural tradition the world is seen as a rational and unitary reality, which exists for the human dialogue as a condition for man’s spiritual growth. We also point out the implications of the affirmation according to which the rationality of the world has multiple virtualities, but its malleability and contingence (...) are brought to the light and put in acts by man, the one who uses these dimensions. We evaluate the importance of these theses from today’s necessity to expand the scientific paradigm of describing the reality, when it is clearly necessary to overcome the classic subject-object duality.

Anselm of Canterbury holds that freedom of the will is a necessary condition for moral responsibility. This condition, however, turns out to be trivially fulfilled by all rational creatures at all times. In order to clarify the necessary conditions for moral responsibility, we must look more widely at his discussion of the nature of the will and of willed action. In this paper, I examine his theory of voluntariness by clarifying his account of the sin of Satan in De (...) casu diaboli. Anselm agrees with Augustine that the sinful act cannot be given a causal explanation in terms of a distinct preceding act of will or desire or choice. He thus rejects volitionalist accounts of Satan's sin and thus of voluntary action in general. He moves beyond his predecessor, however, in insisting on the necessity of an explanation in terms of reasons, and his theory of the dual nature of the rational will is designed to meet this demand. A comparison of Satan's case with the case of the miser of De casu diaboli 3,... (shrink)

Green and Shapiro's critique of rational choice theory underestimates the value of unification and the necessity of universalism in science. The central place of intentionality in social life makes both unification and universalism feasible norms in social science. However, ?universalism? in social science may be partial, in that the independence hypothesis?that the causal mechanism governing action is context independent?may hold only locally in certain classes of choice domains.

How can one knowingly choose against one's best judgment? This is both a traditional philosophical puzzle and a realistic problem in our everyday life. This dissertation is an exposition and examination of a recent work, by George Ainslie, with regard to its innovative explanation as well as rational solution of such a problem. With the help of the new Ainsliean model, I have also sought to offer some analysis of a number of issues that I believe are important to (...) the understanding of the nature of practical rationality. ;The central question for Ainslie's approach to the dynamic problem of preference change is how to justify the "bundling" idea underlying his solution of the problem by adopting a "personal rule." The bundling idea is a belief in the relation between a series of similar choices as each predicting the direction of all the later choices. Being able to think in terms of this bundling idea is a powerful means of abstaining from defection, though it requires considerable cognitive effort. I try to defend the plausibility of such a personal-rule approach. But Ainslie's own account falls short of showing the ultimate necessity of the bundling idea, viz., why the collapse of the whole sequence of choices would necessarily follow from one defection. My argument hinges on demonstrating that neither a causal consideration about the links between similar choices, nor a prudential consideration about the possible risk involved in certain actions is sufficient for understanding the necessity: we need a normative perspective instead. ;This leads to my analysis of the conditions under which a normative solution can be justified. The analysis also delineates the type of dynamic choice situations Ainslie's approach may adequately fit, or have the greatest advantage. Some underlying hypothesis about the status and role of cognition in desire and higher-level motivation is carefully discussed; and the cognitive, deliberative, and affective aspects of the adoption of a rule is explored. During my discussions, I also compare Ainslie's approach with other theories in the domain of practical reasoning, such as that of Donald Davidson's, Jon Elster's, Michael Bratman's, Edward McClennen's, and David Gauthier's, in terms of their explanatory power, or their scope of application, limits, and complementarity. ;Ainslie's motivational model of mind has apparent as well as potential implications for a group of interesting philosophical issues. They include the nature of willpower, the nature of practical rationality as well as moral rules, personal identity, autonomy, and the existentialist theme on self-creation. My conclusion is that the clarification of the metaphysical underpinnings of the Ainsliean model can help to shed some light on these issues. (shrink)
