Definição de IPP da vaca A idade ao primeiro parto (IPP) da vaca, como o próprio nome indica, é a idade em que a vaca tem o seu primeiro parto e, portanto, o seu bezerro(a). Representa o início do retorno econômico do investimento realizado na criação de novilhas. É o ponto de partida onde a vaca começa a produzir descendentes para venda ou reposição e leite para venda, sendo as duas fontes de renda na pecuária de duplo propósito ou dupla (...) aptidão, com criação de raças produtoras de carne e leite. Qual deve ser a IPP da vaca? Para as condições tropicais, espera-se que o primeiro parto da novilha ocorra entre: 29 – 35 meses, o que seria possível se os animais atingissem a gestação aos 20-26 meses de idade. Em condições tropicais, foram relatados valores de idade ao primeiro parto em bovinos mestiços de duplo propósito entre 32 e 48 meses (Aranguren et al., 1993; Rosendo et al., 1993). Isto mostra que existe um amplo valor de melhoria que parece ser basicamente influenciado pela componente nutricional. (shrink)

James Van Cleve has argued that Kant’s Transcendental Deduction of the categories shows, at most, that we must apply the categories to experience. And this falls short of Kant’s aim, which is to show that they must so apply. In this discussion I argue that once we have noted the differences between the first and second editions of the Deduction, this objection is less telling. But Van Cleve’s objection can help illuminate the structure of the B Deduction, and it suggests (...) an interesting reason why the rewriting might have been thought necessary. (shrink)

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people perceive patients in a persistent vegetative state to have less mentality than the dead. Following on from Gomes and Parrott, we provide evidence to show that participants' responses in the initial experiments are an artifact of the questions posed. Results from two experiments show that, once the questions have been clarified, people do not ascribe more mental capacity to the dead than (...) to PVS patients. There is no reason to think that people perceive PVS patients as more dead than dead. (shrink)

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)

1. Introduction The readiness potential was found to precede voluntary acts by about half a second or more (Kornhuber & Deecke, 1965). Kornhuber (1984) discussed the readiness potential in terms of volition, arguing that it is not the manifestation of an attentional processes. Libet discussed it in relation to consciousness and to free will (Libet et al. 1983a; 1983b; Libet, 1985, 1992, 1993). Libet asked the following questions. Are voluntary acts initiated by a conscious decision to act? Are the physiological (...) facts compatible with the belief that free will determines our voluntary acts? What is the role of consciousness in voluntary action? In this paper I will discuss these questions and the answers that Libet gave to them. (shrink)

Claims that necessary and sufficient conditions are not converse relations are discussed, as well as the related claim that If A, then B is not equivalent to A only if B . The analysis of alleged counterexamples has shown, among other things, how necessary and sufficient conditions should be understood, especially in the case of causal conditions, and the importance of distinguishing sufficient-cause conditionals from necessary-cause conditionals. It is concluded that necessary and sufficient conditions, adequately interpreted, are converse relations in (...) all cases. (shrink)

Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that they ignore the full (...) resources that naïve realism has to offer in explaining phenomenal character.

What is the status of the claims which make up Kant’s arguments in the Critique of Pure Reason? This question seemed to Kant’s contemporaries to require a metacritique. Strawson’s criticisms of Kant should be understood in this context: as raising a metacritical challenge about Kant’s grounds for the claims which make up his arguments. What about the claims which make up Strawson’s own arguments in The Bounds of Sense? I argue in this chapter, against what I take to be the (...) general consensus, that Strawson did not and should not have understood these claims to be analytic. Rather he is somewhat puzzlingly committed to our possessing non-analytic but still a priori knowledge of his claims. What could such knowledge consist in? I’ll extract from G.E. Moore’s early writings on Kant a model for understanding such knowledge, one which enables us to better appreciate the way in which Strawson’s methodology dovetails with Kant’s own. (shrink)

It is argued that contraposition is valid for a class of natural language conditionals, if some modifications are allowed to preserve the meaning of the original conditional. In many cases, implicit temporal indices must be considered, making a change in verb tense necessary. A suitable contrapositive for implicative counterfactual conditionals can also usually be found. In some cases, the addition of certain words is necessary to preserve meaning that is present in the original sentence and would be lost or changed (...) in the contrapositive without them. A distinction is made between adding new meaning and adding new words to preserve existing meaning. For concessive conditionals and relevance conditionals, however, no valid contrapositive can be found. They do not belong to the class of contraposable conditionals, which can be independently defined. Difficult cases are also discussed in which the contradictory of the consequent semantically entails the truth of the antecedent. In such cases the content of the antecedent is implicit in the meaning of the consequent. Contraposition becomes possible if what is implicit in the original consequent is made explicit in the contrapositive antecedent. (shrink)

In this paper I distinguish two ways of raising a sceptical problem of others' minds: via a problem concerning the possibility of error or via a problem concerning sources of knowledge. I give some reason to think that the second problem raises a more interesting problem in accounting for our knowledge of others’ minds and consider proposed solutions to the problem.

In the essays which make up The Sovereignty of Good, Iris Murdoch gives us a picture of moral life in which ‘the metaphor of vision [is] almost irresistibly suggested’. This chapter aims to clarify the role played by the metaphor of vision in Murdoch’s philosophical thinking. I’ll examine two different things which might be meant by the term ‘moral vision’: vision of moral things or vision which is itself moral. The suggestion will be that whilst both capture something important about (...) Murdoch’s work, each may mislead about what is distinctive in her views. For Murdoch, I shall suggest, there is no distinctively moral vision. There is only vision: a loving gaze directed upon the reality of others. (shrink)

In this paper I defend the claim that testimony can serve as a basic source of knowledge of other people’s mental lives against the objection that testimonial knowledge presupposes knowledge of other people’s mental lives and therefore can’t be used to explain it.

A commentary is given on Trevena and Miller . The comparability of their experimental task and of the potential they recorded with those used and recorded by Libet, Gleason, Wright, and Pearl is questioned. An interpretation is given for the similarity of event-related potentials recorded when subjects decided to move and when they decided not to move.

The free will problem is defined and three solutions are discussed: no-freedom theory, libertarianism, and compatibilism. Strict determinism is often assumed in arguing for libertarianism or no-freedom theory. It assumes that the history of the universe is fixed, but modern physics admits a certain degree of randomness in the determination of events. However, this is not enough for a compatibilist position—which is favored here—since freedom is not randomness. It is the I that chooses what to do. It is argued that (...) the core of the free will problem is what this I is. A materialist view is favored: The I is an activity of the brain. In addition to absence of external and internal compulsion, freedom involves absence of causal sufficiency of influences acting on the I. A more elaborate compatibilist view is proposed, according to which causal determination is complete when we add events occurring in the I (of which the subject is not conscious). Contrary to what several authors have argued, the onset of the readiness potential before the decision to act is no problem here. The experience of agency is incomplete and fallible, rather than illusory. Some consequences of different views about freedom for the ascription of responsibility are discussed. (shrink)

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

Libet's (2000) arguments in defense of his interpretation of his experimental results are insufficient. The claims of my critical review (Gomes, 2008) do not suffer with his new statements.

We are able to think of empirical objects as capable of existing unperceived. What explains our grasp of this conception of objects? In this paper I examine the claim that experience explains our understanding of objects as capable of existing unperceived with reference to Kant’s Critique of Pure Reason. I argue that standard accounts of experience’s explanatory role are unsatisfactory, but that an alternative account can be extracted from the first Critique – one which relies on Kant’s transcendental idealism.

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people judge patients in a persistent vegetative state to have less mental capacity than the dead. They explain this result by claiming that people have implicit dualist or afterlife beliefs. This essay critically evaluates their experimental findings and their proposed explanation. We argue first that the experiments do not support the conclusion that people intuitively think PVS patients have less mentality than the dead. (...) And second, we provide an alternative explanation of our ascriptions of mentality to the dead and PVS patients, one which turns on Epicurean considerations about the nature of death. (shrink)

Some comments on Quassim Cassam’s Self and World written for a conference at the Institute of Philosophy in 2017. I consider the objection that Cassam raises to Strawson’s argument from unity to objectivity in The Bounds of Sense and raise some general questions about Cassam’s problem of misconception and its application to transcendental arguments.

One of the abiding themes of the three essays which make up Iris Murdoch’s wonderful The Sovereignty of Good1 is that experience can be a way of our coming to possess aesthetic concepts. “We learn through attending to contexts, vocabulary develops through close attention to objects, and we can only understand others if we can to some extent share their [spatio-temporal and conceptual] contexts.” (IP, p.31). My interest in this paper is in what account of aesthetic experience can respect this (...) intuition; that “close attention to objects” can play an important role in our acquisition of aesthetic knowledge and concepts. I want to suggest that certain debates in the philosophy of mind can help us consider how aesthetic experience must be structured in order to play this role. (shrink)

While agreeing with Fischborn’s (2018) contention that, according to one traditional definition of compatibilism, my position should be classified as that of a libertarian incompatibilist, I argue here for a different view of compatibilism. This view involves, on the one hand, local probabilistic causation of decisions (rather than universal strict determinism) and, on the other, free will conceived as involving decisions generated by a decision-making process carried out by the brain, which consciously contemplates different alternatives and could in principle have (...) been different from what it was, implying that the agent could in normal conditions have done otherwise in the same circumstances. After discussing different views of causation (including determinism) and of free will, I make a revision of some passages from my earlier work, quoted by Fischborn. I conclude that what is crucial in the question of (in)compatibilism is the (in)compatibility between freedom of decisions and natural causation of human actions. According to this looser and, I argue, more pertinent view of compatibilism, I maintain my previous classification of my position on the matter as compatibilist. (shrink)

This paper investigates whether 'even if A, B' is pragmatically polysemic, so that a nonconcessive conditional may have 'even if', and whether concessive conditionals, pragmatically defined, can fail to have 'even if' or a non-temporal 'still'. Different paraphrases are used to help elucidate pragmatic meanings. A theory of the pragmatic meanings of concessive and implicative conditionals is presented. The semantic meaning of 'even if' and the question of whether concessive conditionals imply the truth of their consequents are also discussed.

Freedom is often defined by the possibility of doing otherwise. The conditional interpretation of this possibility, advanced by Moore, maintains that to say that someone could have done otherwise is to say that someone would have done otherwise if she had decided to do so. This conception is adequate for the thesis that freedom is compatible with natural causality. The present article presents a defense of this interpretation against the argument with which Lehrer purports to have refuted it. As used (...) in ordinary language, one of the conditionals of the argument has a different sense from that captured in Lehrer’s formalization. In a context that includes the premise that the subject would do otherwise if she decided to do so, the assertion that she could do otherwise only if she decided to do so acquires the meaning that she would do otherwise only if she decided to do so. Without this interpretation, the meaning of ‘can’ in the argument is different from its meaning in ordinary language, since the possibility of doing otherwise would imply really doing otherwise. Abstract in Portuguese: A liberdade é freqüentemente definida pela possibilidade de agir diferentemente. A interpretação condicional dessa possibilidade, proposta por Moore, sustenta que dizer que alguém poderia ter agido diferentemente é dizer que alguém teria agido diferentemente, se assim tivesse decidido. Esta concepção é adequada à tese da compatibilidade entre liberdade e causalidade natural. O presente artigo apresenta uma defesa dessa interpretação contra o argumento com que Lehrer pretendeu contestá-la. Tal como usado na linguagem corrente, um dos condicionais do argumento tem sentido diverso daquele capturado na formalização de Lehrer. No contexto que inclui a premissa de que o sujeito agiria diferentemente se assim decidisse, a afirmaçãode que ele só poderia agir diferentemente se assim decidisse tem o sentido de que ele só agiria diferentemente se assim decidisse. Sem essa reinterpretação, o sentido de ‘poder’, no argumento, distancia-se da linguagem corrente, pois, no caso, poder agir diferentemente implicaria em assim efetivamente agir. (shrink)

A commentary on articles by Klein, Pockett, and Trevena and Miller, in this issue, is given. Average shift in the point of subjective equality , calculated by Klein on Libet's data, and corresponding change in mean shift, calculated by Libet et al. , may be “corrected,” taking as a reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett's main conclusions are (...) favored, but her explanation of peripheral–lemniscal couplings is found to be unconvincing. Trevena and Miller's article unsuccessfully tries to rescue a dualist interactionist view. Libet's method of timing intentions is thoroughly criticized. (shrink)

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot (...) account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge.

According to non-conceptualist interpretations, Kant held that the application of concepts is not necessary for perceptual experience. Some have motivated non-conceptualism by noting the affinities between Kant's account of perception and contemporary relational theories of perception. In this paper I argue (i) that non-conceptualism cannot provide an account of the Transcendental Deduction and thus ought to be rejected; and (ii) that this has no bearing on the issue of whether Kant endorsed a relational account of perceptual experience.

A suinocultura é um dos setores pecuários em constante evolução em termos de pesquisa, genética, modelos produtivos e alternativas alimentares e agroecológicas que conferem ao setor um futuro sustentável. Dito isto, e frente a um setor de grande impacto na cidade de Belo Jardim, bem como do avanço no consumo per capita da carne suína, o objetivo deste trabalho é avaliar, utilizando-se uma revisão bibliográfica sistemática, como a formulação de rações nas fases de crescimento e terminação impactam direta ou indiretamente (...) nas características produtivas e de carcaça e da carne em suínos. Para tanto, foram utilizados artigos de jornais, revistas, periódicos e de anais, bem como livros e manuais que fornecesse alicerce para o tema e que abordassem os principais alimentos empregados na formulação de rações para suínos nessas fases, bem como alimentos alternativos aos convencionais; as necessidades nutricionais nestas fases e, por fim, dietas experimentais que fornecesse impacto positivo no desempenho dos suínos quanto às características da carcaça e da carne.

In the section ‘Unity and Objectivity’ of The Bounds of Sense, P. F. Strawson argues for the thesis that unity of consciousness requires experience of an objective world. My aim in this essay is to evaluate this claim. In the first and second parts of the essay, I explicate Strawson's thesis, reconstruct his argument, and identify the point at which the argument fails. Strawson's discussion nevertheless raises an important question: are there ways in which we must think of our experiences (...) if we are to self-ascribe them? In the third part of the essay, I use Kant's remarks concerning the passivity of experience to suggest one answer to this question: in self-ascribing experiences, we must be capable of thinking of them as passive to their objects. This can be used to provide an alternative route from unity to objectivity. (shrink)

Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is necessarily involved in the (...) perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding. (shrink)

What method should we use to determine the nature of perceptual experience? My focus here is the Kantian thought that transcendental arguments can be used to determine the nature of perceptual experience. I set out a dilemma for the use of transcendental arguments in the philosophy of perception, one which turns on a comparison ofthe transcendental method with the first-personal method of early analytic philosophy, and with the empirical methods of much contemporary philosophy of mind. The transcendental method can avoid (...) this dilemma only if it commits to our possessing a capacity for imaginative reflection, one which is capable of identifying certain formal properties of experience.This result indicates some of the commitments which must be made if transcendental arguments are to be used in the philosophy of perception, and it has implications for those views that take the philosophy of perception to be autonomous of the empirical science of perception.

The aim of the Analytic of Concepts is to derive and deduce a set of pure concepts of the understanding, the categories, which play a central role in Kant’s explanation of the possibility of synthetic a priori cognition and judgment. This chapter is structured around two questions. First, what is a pure concept of the understanding? Second, what is involved in a deduction of a pure concept of the understanding? In answering the first, we focus on how the categories differ (...) from the pure forms of sensibility and examine whether they are known only to be the pure forms of human thinking or rather the forms of discursive cognition as such. In answering the second, we draw a distinction between the application and the exemplification of the categories and use it to identify different ways of understanding Kant’s project in the Transcendental Deduction of the Categories. These questions connect because the answer to the first determines how we should understand the kind of entitlement which is to be established in the Deduction. (shrink)

Hodgson’s (Journal of Consciousness Studies, 12 (1), 2005) defense of the plain person’s view that free will exists in conscious voluntary action is discussed. His position against the view that human action is automatically determined is favored, but his view that free will is incompatible with natural causation is countered. Eccles’ hypothesis to account for the presence of a readiness potential prior to a conscious decision to act now is discussed. It is argued that it is possible to preserve what (...) is good in a plain person’s concept of free will in a way that is compatible with natural causation. (shrink)

An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125-300 ms minimum value (...) for the latency for conscious sensation of threshold skin stimuli. Backward enhancement is not suitable for inferring this latency. For determining temporal relations between stimuli that correspond to subjects' reports, theendof cerebral Minimum Train Duration should be used as reference, rather than its onset. Results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli. Results of coupling peripheral stimuli and stimuli to medial lemniscus (LM) are explained by a shorter LM latency and/or a longer peripheral latency. This interpretation suggests a 230 ms minimum value for the latency for conscious sensation of somatosensory near-threshold stimuli. The backward referral hypothesis, as formulated by Libet, should not be retained. Long readiness potentials preceding spontaneous conscious or nonconscious movements suggest that both kinds of movement are nonconsciously initiated. The validity of Libet's measures of W and M moments (Libet et al., 1983a) is questionable due to problems involving latencies, training, and introspective distinction of W and M. Veto of intended actions may be initially nonconscious but dependent on conscious awareness. (shrink)

In a provocative article published in the Journal of Consciousness Studies, Susan Pockett argues for the plausibility of considering consciousness as an epiphenomenon of neural activity. This means that consciousness, though caused by the brain, would not in its turn have any role in the causation of neural activity and, consequently, of behaviour. Critical for her argument is the distinction she makes between 'consciousness per se' and 'the neural processing that accompanies it' . In her discussion, though, the author begs (...) the question concerning whether there really is such 'consciousness itself, as distinct from the neural processing that goes with it' . If consciousness as it exists happens not to be distinct from some sort of neural processing, then Pockett's 'consciousness per se' has no causal effect simply because it does not exist. (shrink)

The prima facie heterogeneity between psychical and physical phenomena seems to be a serious objection to psychoneural identity thesis, according to many authors, from Leibniz to Popper. It is argued that this objection can be superseded by a different conception of consciousness. Consciousness, while being conscious of something, is always unconscious of itself . Consciousness of being conscious is not immediate, it involves another, second-order, conscious state. The appearance of mental states to second-order consciousness does not reveal their true nature. (...) Psychoneural identity can thus be considered a valid hypothesis. Related views of Kant, Freud, Shaffer, Bunge and others are considered. “Naive psychical realism” is criticised. Consciousness of mental events is considered as the result of the action of a cerebral system that observes the neural events hypothetically identical to mental events. The theory combines a materialist view with a due consideration of subjective experience. (shrink)

Reinterpretations of Libet's results have received support from most commentaries. Libet's arguments against alternative hypotheses are contested. Latency depends on intensity. Integration of intensity and duration explains the Minimum Train Duration. Analogies of Libet's timing of intentions with control experiments indicate biases of opposite signs, according to intramodal or intermodal results. Rosenthal's view of nonconscious intentions becoming conscious after a delay is favored. Compatibilist free will is discussed.

Recent debates in the interpretation of Kant’s theoretical philosophy have focused on the nature of Kantian intuition and, in particular, on the question of whether intuitions depend for their existence on the existence of their objects. In this paper we show how opposing answers to this question determine different accounts of the nature of Kantian cognition and we suggest that progress can be made on determining the nature of intuition by considering the implications different views have for the nature of (...) cognition.

Scepticism is sometimes expressed about whether there is any interesting problem of other minds. In this paper I set out a version of the conceptual problem of other minds which turns on the way in which mental occurrences are presented to the subject and situate it in relation to debates about our knowledge of other people's mental lives. The result is a distinctive problem in the philosophy of mind concerning our relation to other people.

In the first part of this chapter, I summarise some of the issues in the philosophy of mind which are addressed in Kant’s Critical writings. In the second part, I chart some of the ways in which that discussion influenced twentieth-century analytic philosophy of mind and identify some of the themes which characterise Kantian approaches in the philosophy of mind.

P.F. Strawson (1919-2006) was one of the most significant philosophers of the twentieth-century. His career centred around Oxford – first as Tutor and Fellow at University College, then as Waynflete Professor of Metaphysical Philosophy at Magdalen College. His careful, thoughtful, and characteristically elegant written work was influential in moving Oxford philosophy from the anti-metaphysical leanings of A.J. Ayer and J.L. Austin to a renewed and rejuvenated era of traditional philosophy theorising, albeit domesticated in a distinctively Strawsonian fashion. His influence on (...) British philosophy persists through a generation of students who were brought up on his writings. (shrink)

Lucy Allais seeks to provide a reading of the Transcendental Deduction of the Categories which is compatible with a nonconceptualist account of Kant’s theory of intuition. According to her interpretation, the aim of the Deduction is to show that a priori concept application is required for empirical concept application. I argue that once we distinguish the application of the categories from the instantiation of the categories, we see that Allais’s reconstruction of the Deduction cannot provide an answer to Hume’s problem (...) about our entitlement to use a priori concepts when thinking about the objects of empirical intuition. If the Deduction is to provide a response to Hume, Allais’s interpretation must be rejected. (shrink)

An examination of conditionals in di¤erent languages leads to a distinction of three types of conditionals instead of the usual two (indicative and subjunctive). The three types can be explained by the degree of acceptance or as-if acceptance of the truth of the antecedent. The labels subjunctive and indicative are shown to be inadequate. So-called indicative conditionals comprise two classes, the very frequent uncertain-fact conditionals and the quite rare accepted-fact conditionals. Uncertain-fact conditionals may have a time shift in contemporary English (...) and the future subjunctive in Portuguese (though not all of them do). Moreover, paraphrases of if with in case or supposing are usually possible with approximately the same meaning. Accepted-fact conditionals never have these features. (shrink)

Can the experience of great art play a role in our coming to understand the ethical framework of another person? In this article I draw out three themes from Iris Murdoch’s ‘The Sovereignty of Good’ in order to show the role that communal attention to works of art can play in our ethical lives. I situate this role in the context of Murdoch’s wider philosophical views.

‘How, then, she had asked herself, did one know one thing or another thing about people, sealed as they were?’ So asks Lily Briscoe in To the Lighthouse. It is this question, rather than any concern about pretence or deception, which forms the basis for the philosophical problem of other minds. Responses to this problem have tended to cluster around two solutions: either we know others’ minds through perception; or we know others’ minds through a form of inference. In the (...) first part of this paper I argue that this debate is best understood as concerning the question of whether our knowledge of others’ minds is based on perception or based on evidence. In the second part of the paper I suggest that our ordinary ways of thinking take our knowledge of others’ minds to be both non- evidential and non-perceptual. A satisfactory resolution to the philosophical problem of other minds thus requires us to take seriously the idea that we have a way of knowing about others’ minds which is both non-evidential and non-perceptual. I suggest that our knowledge of others’ minds which is based on their expressions – our expressive knowledge - may fit this bill. (shrink)

Quassim Cassam has recently defended a perceptual model of knowledge of other minds: one on which we can see and thereby know that another thinks and feels. In the course of defending this model, he addresses issues about our ability to think about other minds. I argue that his solution to this 'conceptual problem' does not work. A solution to the conceptual problem is necessary if we wish to explain knowledge of other minds.
