The minimal God exemplifies essential omnipotence, omniscience, and moral perfection, but none of the other properties of the traditional God. I examine the consequences of the minimal God in augmented S5, S4, and Kρσ. The metaphysical consequences for the minimal God in S5 include the impossibility that God—or any other object—might acquire, lose, or exchange an essential property. It is impossible that an essentially divine being might become essentially human, for instance. The epistemological consequences include the impossibility of agnosticism—it is (...) impossible that P(◻︎FG |E) = P(~◻︎FG| E). Indeed, every weaker forms of agnosticism are also impossible—it is impossible that P(◻︎FG |E) = n, n(0 < n < 1). The metaphysical and epistemological consequences for the minimal God in S4 are equally untenable. I show that we can avoid all of these unwelcome epistemological consequences for the minimal God in Kρσ. But Kρσ has some extraordinary metaphysical consequences for the minimal God. All of the problems for the minimal God generalize to the maximal God. (shrink)

Neste trabalho abordamos as contribuições de Larry Laudan para a questão do progresso científico.

Michael J. Almeida presents a bold new defence of the existence of God. He argues that entrenched principles in philosophical theology which have served as basic assumptions in apriori, atheological arguments are in fact philosophical dogmas. Almeida argues that not only are such principles false - they are necessarily false.

This paper focuses on the effects of motivational biases on the way people reason and debate in everyday life. Unlike heuristics and cognitive biases, motivational biases are typically caused by the influence of a desire or an emotion on the cognitive processes involved in judgmental and inferential reasoning. In line with the ‘motivational’ account of irrationality, I argue that these biases are the cause of a number of fallacies that ordinary arguers commit unintentionally, particularly when the commitment to a given (...) viewpoint is very strong. Drawing on recent work in argumentation theory and psychology, I show that there are privileged links between specific types of biases and specific types of fallacies. This analysis provides further support to the idea that people’s tendency to arrive at desired conclusions hinges on their ability to construct plausible justifications for those conclusions. I suggest that this effort to rationalize biased views is the reason why unintentional fallacies tend to be persuasive. (shrink)

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

The paper aims to show that, if S5 is the logic of metaphysical necessity, then no state of affairs in any possible world constitutes any non-trivial evidence for or against the existence of the traditional God. There might well be states of affairs in some worlds describing extraordinary goods and extraordinary evils, but it is false that these states of affairs constitute any (non-trivial) evidence for or against the existence of God. The epistemological and metaphysical consequences for philosophical theology of (...) assuming that S4 or Kσρ is the logic of metaphysical necessity are equally untenable. S4 guarantees that God does not exist if there is the slightest evidence against the existence of God. And Kσρ guarantees that God might survive the loss or acquisition of any essential property at all. (shrink)

ABSTRACT: Recent work in moral theory includes an intriguing new argument that the vagueness of moral properties, together with two well-known and well-received metaethical principles, entails the incredible conclusion that it is impossible to be moral. I show that the argument equivocates between “it is true that A and B are morally indistinguishable” and “it is not false that A and B are morally indistinguishable.” As expected the argument is interesting but unsound. It is therefore not impossible to be moral.RÉSUMÉ: (...) Les travaux récents en théorie morale comprennent un nouvel argument intrigant voulant que le caractère vague des propriétés morales, joint à deux principes métaéthiques bien connus et généralement admis, entraîne une conclusion incroyable, soit qu’il est impossible d’être moral. Je montre que cet argument entretient l’équivoque entre «il est vrai que A et B sont moralement impossibles à distinguer» et «il n’est pas faux que A et B soient moralement impossibles à distinguer». Comme on s’y attendait, l’argument est intéressant mais mal fondé. Il n’est donc pas impossible d’être moral. (shrink)

_The Metaphysics of Perfect Beings_ addresses the problems an Anselmian perfect being faces in contexts involving unlimited options. Recent advances in the theory of vagueness, the metaphysics of multiverses and hyperspace, the theory of dynamic or sequential choice, the logic of moral and rational dilemmas, and metaethical theory provide the resources to formulate the new challenges and the Anselmian responses with an unusual degree of precision. Almeida shows that the challenges arising in the unusual contexts involving unlimited options sometimes (...) produce metaphysical surprise. (shrink)

The standard position on moral perfection and gratuitous evil makes the prevention of gratuitous evil a necessary condition on moral perfection. I argue that, on any analysis of gratuitous evil we choose, the standard position on moral perfection and gratuitous evil is false. It is metaphysically impossible to prevent every gratuitously evil state of affairs in every possible world. No matter what God does—no matter how many gratuitously evil states of affairs God prevents—it is necessarily true that God coexists with (...) gratuitous evil in some world or other. Since gratuitous evil cannot be eliminated from metaphysical space, the existence of gratuitous evil presents no objection to essentially omnipotent, essentially omniscient, essentially morally perfect, and necessarily existing beings.

Nick Trakakis and Yujin Nagasawa criticise the argument in Almeida and Oppy . According to Trakakis and Nagasawa, we are mistaken in our claim that the sceptical theist response to evidential arguments from evil is unacceptable because it would undermine ordinary moral reasoning. In their view, there is no good reason to think that sceptical theism leads to an objectionable form of moral scepticism. We disagree. In this paper, we explain why we think that the argument of Nagasawa and (...) Trakakis fails to overthrow our objection to sceptical theism. (shrink)

A Crítica de Hume ao Argumento do Desígnio José Oscar de Almeida Marques Dep. de Filosofia – UNICAMP -/- RESUMO: É comum considerar que o chamado “argumento do desígnio” (o argumento a posteriori para provar a existência de Deus a partir da ordem e funcionalidade do mundo) teria sido refutado ou seriamente abalado por Hume. Mas a natureza e o alcance dessa alegada refutação são problemáticos, pois Hume muitas vezes expressou suas críticas através de seus personagens e evitou assumi-las (...) diretamente enquanto autor. Em vez de supor que Hume procedeu dessa forma apenas para disfarçar suas verdadeiras convicções e evitar um conflito com as autoridades eclesiásticas, proponho que sua posição nesse assunto não é tão categórica como às vezes se supõe, e que os famosos argumentos de Filo nos Diálogos mostram apenas que é possível que a ordem e funcionalidade do mundo tenham surgido sem a intervenção de um desígnio consciente, mas não podem por si sós dar a essa hipótese o mínimo grau de plausibilidade necessário para torná-la digna de uma séria consideração. De fato, antes da revolução explicativa operada por Darwin um século depois, ninguém estava realmente em condições de vislumbrar uma alternativa plausível à atuação de algum tipo de inteligência na geração da ordem e funcionalidade do mundo. ------------ Some Remarks on Hume’s Critique of the Argument from Design José Oscar of Almeida Marques Dep. of Philosophy - UNICAMP -/- ABSTRACT: The so-called “argument from design” (the a posteriori argument to prove the existence of God from the order and functionality of the world) is commonly considered to have been refuted or seriously impaired by Hume. But the nature and scope of this alleged refutation is problematic because Hume often expressed his critics through other characters’ mouth and avoided to assume them directly as author. Contrarily to the supposition that Hume proceeded in this way only to disguise his true convictions and to avoid a confrontation with the ecclesiastical authorities, I propose that his stance on the matter is not, in fact, as clear-cut as it is sometimes supposed, and that Philo’s famous arguments in the Dialogues show only that it is possible for the order and functionality of the world to have arisen without the intervention of an intelligent design, but cannot by themselves lend to this hypothesis the least degree of plausibility needed to make it worthy of serious consideration. In fact, before the explanatory revolution inaugurated by Darwin a century later, nobody was in position to envisage a plausible alternative to the operation of some sort or other of intelligence in the generation of the order and functionality of the world.

Perhaps the greatest impediment to a viable libertarianism is the provision of a satisfactory explanation of how actions that are undetermined by an agent's character can still be under the control of, or ‘up to’, the agent. The ‘luck problem’ has been most assiduously examined by Robert Kane who supplies a detailed account of how this problem can be resolved. Although Kane's theory is innovative, insightful, and more resourceful than most of his critics believe, it ultimately cannot account for the (...) type of control that moral responsibility and (ultimate) agency legitimately require.

According to Paul Draper and Ryan Nichols the practice of philosophy of religion—and especially its theistically committed practitioners—regularly violate norms of rationality, objectivity, and impartiality in the review, assessment, and weighing of evidence. (Draper and Nichols, 2013). We consider the charge of epistemic partisanship and show that the observational data does not illustrate a norm-violating form of inquiry. The major oversight in the charge of epistemic partiality is the epistemically central role of prior probabilities in determining the significance of incongruent (...) evidence. We argue that reasonably divergent views on the likelihood of theism on incongruent evidence can also account for differences in significance. We conclude that it is an epistemic requirement that committed theists regard incongruent evils as much less significant evidence against theism than do lukewarm theists, agnostics, or atheists. Differences in the significance of evidence quite properly reflect differences in commitments to theism. (shrink)

The main aim in the forthcoming discussion is to contrast theistic modal realism and theistic actualist realism. Actualist realism is the dominant view among theists and presents the most serious challenge to theistic modal realism. I discuss various prominent forms of theistic actualist realism. I offer reasons for rejecting the view of metaphysical reality that actualist realism affords. I discuss theistic modal realism and show that the traditional conception of God is perfectly consistent with the metaphysics of genuine modal realism. (...) Indeed theistic modal realism is more suited to traditional theism than is any version of actualist realism. (shrink)

I consider the most serious problem for the traditional account of divine creation in theistic actualism. According to van Inwagen's modal collapse argument, ultimate explanation entails that gratitude to God for one's existence is totally inappropriate. Ultimately, the actual world, and everything in it, is self-explanatory, and not a consequence of divine creation. I argue that van Inwagen's argument is unsound. It is consistent with an ultimate explanation for the world that the actual world is contingently necessary. If God actualizes (...) the world as a matter of contingent necessity, then gratitude to God for one's existence is perfectly appropriate. It is true that we exist as a matter of necessity, but that necessary existence is just a contingent fact. There are possible worlds in which we fail to exist altogether. (shrink)

Discussions of divine simplicity generally overlook the distinction between identity claims that are reductivist and identity claims that are eliminativist. If, for instance, the identity claim that 'the chair = a configuration of particles' is merely reductive, then there exist chairs and there exist configurations of particles and it turns out that they are identical. The identity in this case does not reduce the ontological complexity of the world. But if the identity claim is eliminativist, then it is true again (...) that chairs are configurations of particles, but chairs do not in fact exist. The illusory object that we call a chair turns out to be nothing over and above a configuration of physical particles. The chair reduces to the configuration of particles without remainder. The defense of divine simplicity in this paper argues that it is in this eliminativist sense that God's intrinsic properties are identical to God. (shrink)

In the Critique of the Power of Judgement, Kant claims that ‘the English taste in gardens or the baroque taste in furniture pushes the freedom of the imagination almost to the point of the grotesque’ (KU 5:242). This paper attempts to reconstruct Kant’s views on the grotesque as a theoretical foundation for the modern conception of the grotesque as a negative aesthetic category. The first section of the paper considers and ultimately rejects the interpretation of the grotesque as a difficult (...) kind of beauty. The second section contrasts the experience of the grotesque with similar experiences of sublimity and dreams. The third section examines the discord between faculties underlying the experience of the grotesque, defining the grotesque as a subclass of ugliness and addressing potential objections to its inclusion in Kant’s aesthetics. The fourth and final section briefly discusses the specificity of the grotesque as a subclass of ugliness. (shrink)

In ‘Evil is Still Evidence: Comments on Almeida’ Robert Bass presents three objections to the central argument (ENE) in my ‘Evil is Not Evidence’. The first objection is that ENE is invalid. According to the second objection, it is a consequence of ENE that there can be no evidence for or against a posteriori necessities. The third objection is that, contrary to ENE, the likelihood of certain necessary identities varies with the evidence we have for them. In this reply (...) I explain why ENE has exactly none of the implications described by Bass. I argue in the concluding section that there is a modal solution to the epistemological problems presented by ENE. (shrink)

Property-identical divine-command theory (PDCT) is the view that being obligatory is identical to being commanded by God in just the way that being water is identical to being H2O. If these identity statements are true, then they express necessary a posteriori truths. PDCT has been defended in Robert M. Adams (1987) and William Alston (1990). More recently Mark C. Murphy (2002) has argued that property-identical divine-command theory is inconsistent with two well-known and well-received theses: the free-command thesis and the supervenience (...) thesis. I show that Murphy's argument is vitiated by mistaken assumptions about the substitutivity of metaphysical identicals in contexts of supervenience. The free-command thesis and the supervenience thesis therefore pose no serious threat to PDCT. (Published Online August 11 2004). (shrink)

It is commonly believed that intrinsically bad possible worlds are inconsistent with the perfect goodness of God. A perfectly good being could not exist in possible worlds that are intrinsically bad. Indeed it is widely believed that possible worlds that are insufficiently good are inconsistent with a perfectly good God. Modal atheological arguments aim to show that, since the pluriverse includes intrinsically bad worlds and insufficiently good worlds, there necessarily does not exist a perfectly good God. I show that modal (...) atheological arguments are in general invalid. Modal atheological arguments fail to show that there exists no perfectly good God even on the assumption that there are extremely bad worlds in the pluriverse. Modal atheological arguments depend entirely on the logic of modality in S5. But the logic of S5 ensures that a perfectly good God is consistent with extremely bad possible worlds and so guarantees that a perfectly good God is consistent with a plenitudinous pluriverse.

I examine the difficulties involved in the Aristotelian proposal to identify the knowledge of “what it is” and “why it is”, in order to better understand the outlines that delimit it. I propose that the connections by which Aristotle links definition and explanation, and hence essence and cause, depend on the mutual convertibility between nominal expressions and predicative sentences.

‘Intentionalist’ approaches portray self-deceivers as “akratic believers”, subjects who deliberately choose to believe p despite knowing that p is false. In this paper I argue that the intentionalist model leads to a number of paradoxes that seem to undermine it. I claim that these paradoxes can nevertheless be overcome in light of the rival hypothesis that self-deception is a non-intentional process that stems from the influence of emotions upon cognitive processes. Furthermore, I propose a motivational interpretation of the phenomenon of (...) ‘hyperbolic discounting bias’ which highlights the role of emotional biases in akratic behavior. Finally, I argue that we are not the helpless victims of our irrational attitudes, insofar as we have the ability – and arguably the epistemic obligation – to counteract motivational biases.

I provide the account of divine creation found in multiverse theorists Donald Turner, Klaas Kraay, and Tim O’Connor. I show that the accounts Kraay and Turner offer are incoherent. God does not survey all possible worlds and necessarily actualize those universes in the (on balance) good worlds or the worthy worlds. If God necessarily actualizes the multiverse, we have no idea which universes are parts of that multiverse. I show next that Tim O’Connor’s multiverse account of creation is also incoherent. (...) I argue that a preferable multiverse would include a much greater variety of universes than are included in Turner, Kraay or O’Connor. In the last section I offer some concluding remarks. (shrink)

Pretende-se auscultar a possibilidade de instrução moral pela literatura. Defender-se-á que a arte narrativa é capaz de instruir moralmente pois 1) proporciona um tipo de conhecimento não-proposicional que permite o acesso a novas perspetivas, e 2) é capaz de cultivar e refinar os valores e as práticas morais dos leitores, através do engajamento emocional. Tentar-se-á mostrar que o poder inverso — o poder de corromper moralmente — não se verifica (ou não se verifica tão facilmente): apelar-se-á à resistência imaginativa humana (...) que parece impedir que o Homem exporte perspetivas morais que violentam o seu próprio posicionamento axiológico.

William Rowe has argued that if there is an infinite sequence of improving worlds then an essentially perfectly good being must actualize some world in the sequence and must not actualize any world in the sequence. Since that is impossible, there exist no perfectly good beings. I show that Rowe's argument assumes that the concept of a maximally great being is incoherent. Since we are given no reason to believe that the concept of a maximally great being is incoherent we (...) have no reason to believe Rowe's Argument from Improvability is sound. (shrink)

Most theists do not put a (subjective) probability of 1 (certainty) on God's existence. Most atheists do not put a probability of 0 on God's existence. I argue that these familiar positions are incoherent. On the assumption of S5 and the probability calculus it can be shown that the only coherent (subjective) probabilities an agent can assign to God's existence/non-existence are 0 or 1. Believers must be completely committed believers and non-believers must be completely committed non-believers. Agnosticism is not a (...) coherent position. (shrink)

Estas reflexões têm como principal objetivo mostrar como a concepção do belo em Agostinho de Hipona é tributária da tradição platônico-aristotélica e das Escrituras. No que tange à primeira influência, a ênfase é colocada nas noções de simetria, de proporção, de forma, de unidade e, portanto, de belo. No que diz respeito às Escrituras, Agostinho considera em primeiro lugar o papel da criação e a ação de Deus no universo como o Ser a partir do qual todas as coisas se (...) mantêm harmônica e proporcionalmente vinculadas entre si. Neste universo, ao pôr o acento sobre o homem como a imagem e semelhança de Deus, o teólogo explora igualmente o conceito de participação, que também remete a Platão e às Escrituras. O texto termina apontando para o paradoxo, tipicamente estoico, do apesar de, isto é, apesar do mal, existe o bem, apesar do feio e do desgracioso, existe o belo. (shrink)

Neste ensaio, debruçamo-nos sobre o movimento anti-humanista que, partindo da crítica de Nietzsche, atinge o seu zénite em Foucault. Depois de uma breve análise crítica às conceções que depositavam uma inabalável fé nas capacidades do Homem para entender, interpretar e recriar o mundo exterior, defenderemos como o ponto de vista estruturalista permite melhor iluminar a real posição do Homem no mundo e, adicionalmente, estabelecer um novo paradigma segundo o qual se possam abrir e prosseguir novos caminhos que conduzam à evolução (...) e emancipação do ser humano.

There has been considerable debate in legal philosophy about how to attribute purposes to rules. Separately, within cognitive science, there has been a growing body of research concerned with questions about how people ordinarily attribute purposes. Here, we argue that these two separate fields might be connected by experimental jurisprudence. Across four studies, we find evidence for the claim that people use the same criteria to attribute purposes to physical objects and to rules. In both cases, purpose attributions appear to (...) be governed not so much by original intention or by moral value as by current practice. We argue that these findings in the cognitive science of purpose attribution have implications for jurisprudential questions involving purposivist legal interpretation. (shrink)

Assuming divine command theory is true, there are no moral limits on the commands God can issue. Nevertheless there are no possible worlds in which divine command theory is true and God commands cruelty for its own sake or the sacrifice of ten-year-olds in a gruesome ritual, or anything of the kind. The main conclusion of the argument is that God cannot command the morally horrible not because of God's moral perfection or God's lack of power, of God's kindness, etc., (...) but because commanding the morally horrible entails a contradiction. I show that the argument is an instance of a valid and uncontroversial counterfactual sequent. Divine command theory entails that there are commands that even an omnipotent and morally unconstrained being cannot issue. (shrink)

In this paper I draw together the notion of the absent referent as proposed by Carol J. Adams, and the notions of literal and symbolical sacrifice by eating the other — or ingestion — advanced by Jacques Derrida, to characterize how animals are commonly perceived, which ultimately forbids productive arguments for vegetarianism. I discuss animals as being literally and definitionally absent referents, and I argue, informed by Derrida’s philosophy, that it is impossible to aim at turning them into present referents (...) without reinforcing symbolic ingestion by linking symbolic ingestion to epistemic appropriation or conceptualization. With this, I highlight the ethical importance of discussing symbolic ingestion in animal philosophy. (shrink)

Michael Martin introduces a non-Humean conception of miracles according to which miracles are events that need not violate a law of nature and are brought about by the exercise of a possibly non-theistic, supernatural power. Call those m-miracles. I consider Martin’s argument that the occurrence of an m-miracle would not confirm the existence of God. Martin presents an interesting argument, but it does not establish that m-miracles would not confirm the existence God. I argue that, on the contrary, it is (...) quite reasonable to conclude that Martin’s m-miracles provide at least some confirmation for the hypothesis that God exists. (shrink)

Ted Sider’s Proportionality of Justice condition requires that any two moral agents instantiating nearly the same moral state be treated in nearly the same way. I provide a countermodel in supervaluation semantics to the proportionality of justice condition. It is possible that moral agents S and S' are in nearly the same moral state, S' is beyond all redemption and S is not. It is consistent with perfect justice then that moral agents that are not beyond redemption go determinately to (...) heaven and moral agents that are beyond all redemption go determinately to hell. I conclude that moral agents that are in nearly the same moral state may be treated in very unequal ways. (shrink)

É comumente aceito, atualmente, que Aristóteles não teria enfrentado ou tentado seriamente resolver o famoso paradoxo do mentiroso, embora ele tenha sido formulado por Eubúlides de Mileto, membro da escola megárica e rival filosófico de Aristóteles. No máximo, assim reza a visão tradicional, ele parece apenas fazer uma menção desse paradoxo nas Refutações sofísticas, Capítulo 25, talvez esboçando a sua solução. O meu intento, no presente artigo, é desafiar essa opinião geral mostrando que o Estagirita fornece uma explicação implícita para (...) duas versões do paradoxo do mentiroso, a saber, a versão autorreferencial (que pode ser apresentada pela declaração: “esta declaração é falsa”), e a versão anafórica (que pode ser apresentada por meio de duas declarações mutuamente referentes como estas: “a próxima declaração é verdadeira” e “a declaração anterior é falsa”). A minha alegação é que a solução aristotélica para essas duas versões do paradoxo encontra-se no núcleo de sua refutação de duas teses, as quais denominei como tese da synalethia (que defende que toda declaração é verdadeira) e como tese da sympseudia (que defende que toda declaração é falsa). Tal refutação é realizada no oitavo capítulo do quarto Livro da Metafísica, um texto até agora subestimado pelos intérpretes modernos, mesmo sendo a parte final de um dos mais importantes escritos de Aristóteles. A solução aristotélica, assim defendo, é levada a cabo por meio dos seguintes princípios: (i) toda declaração é sempre precedida por um operador de verdade da forma ‘é verdade que...’, ou seja, toda declaração, qualquer que seja o que ela possa declarar a mais, primariamente assevera a sua própria verdade; e, em conformidade com o princípio anterior, (ii) toda declaração que assevera a sua própria falsidade ou acarreta a verdade de sua contraditória é necessariamente falsa. Através desses princípios, a refutação de Aristóteles da synalethia e da sympseudia é bem-sucedida. Mostrarei que obtemos uma boa solução para as versões do mentiroso acima mencionadas (e implicitamente presentes nas posições refutadas), apenas aplicando esses mesmos princípios a elas. Esse tipo de solução ao mentiroso tanto quanto para as teses antes citadas é muito parecido com aquele explicitamente encontrado nas obras de diversos filósofos, a saber, Guilherme de Sherwood, Tomás Bradwardine, João Buridano, Alberto da Saxônia, Paulo Venetus, Charles S. Peirce e Arthur Prior. Assim, também defendo que essa linhagem tem as suas raízes na solução de Aristóteles. (shrink)

The book discusses the structure, content, and evaluation of cosmological arguments. The introductory chapter investigates features essential to cosmological arguments. Traditionally, cosmological arguments are distinguished by their appeal to change, causation, contingency or objective becoming in the world. But none of these is in fact essential to the formulation of cosmological arguments. Chapters 1-3 present a critical discussion of traditional Thomistic, Kalam, and Leibnizian cosmological arguments, noting various advantages and disadvantages of these approaches. Chapter 4 offers an entirely new approach (...) to the cosmological argument - the approach of theistic modal realism. The proper explananda of cosmological arguments on this approach is not change, causation, contingency or objective becoming in the world. The proper explananda is the totality of metaphysical reality - all actualia and all possibilia. The result is the most compelling and least objectionable version of the cosmological argument.
