In this article, through a critical examination of K. Brad Wray's version of the argument from underconsideration against scientific realism, I articulate a modest version of scientific realism. This modest realist position, which I call ‘relative realism’, preserves the scientific realist's optimism about science's ability to get closer to the truth while, at the same time, taking on board the antirealist's premise that theory evaluation is comparative, and thus that there are no good reasons to think that (...) science's best theories are close to the truth.

Scientific antirealists run the argument from underconsideration against scientific realism. I argue that the argument from underconsideration backfires on antirealists’ positive philosophical theories, such as the contextual theory of explanation (van Fraassen, 1980), the English model of rationality (van Fraassen, 1989), the evolutionary explanation of the success of science (Wray, 2008; 2012), and explanatory idealism (Khalifa, 2013). Antirealists strengthen the argument from underconsideration with the pessimistic induction against current scientific theories. In (...) response, I construct a pessimistic induction against antirealists that since antirealists generated problematic philosophical theories in the past, they must be generating problematic philosophical theories now.

Argument from analogy is a common and formidable form of reasoning in law and in everyday conversation. Although there is substantial literature on the subject, according to a recent survey ( Juthe 2005) there is little fundamental agreement on what form the argument should take, or on how it should be evaluated. Th e lack of conformity, no doubt, stems from the complexity and multiplicity of forms taken by arguments that fall under the umbrella of analogical (...) reasoning in argumentation, dialectical studies, and law. Modeling arguments with argumentation schemes has proven useful in attempts to refine the analyst’s understanding of not only the logical structures that shape the backbone of the argument itself, but also the logical underpinning of strategies for evaluating it, strategies based on the semantic categories of genus and relevance. By clarifying the distinction between argument from example and argument from analogy, it is possible to advance a useful proposal for the treatment of argument from analogy in law. (shrink)

One motivation for preferring the many worlds interpretation of quantum mechanics over realist rivals, such as collapse and hidden variables theories, is that the interpretation is able to preserve locality (in the sense of no action at a distance) in a way these other theories cannot. The primary goal of this paper is to make this argument for the many worlds interpretation precise, in a way that does not rely on controversial assumptions about the metaphysics of many worlds.

Accounts of arguments from expert opinion take it for granted that expert judgments count as (defeasible) evidence for propositions, and so an argument that proceeds from premises about what an expert judges to a conclusion that the expert is probably right is a strong argument. In Mizrahi (2013), I consider a potential justification for this assumption, namely, that expert judgments are significantly more likely to be true than novice judgments, and find it wanting because of empirical (...) evidence suggesting that expert judgments under uncertainty are not significantly more likely to be true than novice judgments or even chance. In this paper, I consider another potential justification for this assumption, namely, that expert judgments are not influenced by the cognitive biases novice judgments are influenced by, and find it wanting, too, because of empirical evidence suggesting that experts are vulnerable to pretty much the same cognitive biases that novices are vulnerable to. If this is correct, then the basic assumption at the core of accounts of arguments from expert opinion, namely, that expert judgments count as (defeasible) evidence for propositions, remains unjustified.

The Lewis-Sider argument from vagueness is one of the most powerful objections against restricted composition. Many have resisted the argument by rejecting its key premise, namely that existence is not vague. In this paper, I argue that this strategy is ineffective as a response to vagueness-based objections against restricted composition. To that end, I formulate a new argument against restricted composition: the argument from determinate vagueness. Unlike the Lewis-Sider argument, my argument doesn’t (...) require accepting that existence is not vague, but only that it is not vague in a specific way, which, I argue, is entailed by restricted composition. I show that the rejection of this species of vague existence follows from assumptions even friends of vague existence should be happy to accept. (shrink)

The Argument from Temporary Intrinsics is one of the canonical arguments against endurantism. I show that the two standard ways of presenting the argument have limited force. I then present a new version of the argument, which provides a more promising articulation of the underlying objection to endurantism. However, the premises of this argument conflict with the gauge theories of particle physics, and so this version of the argument is no more successful than its (...) predecessors. I conclude that no version of the Argument from Temporary Intrinsics gives us a compelling reason to favor one theory of persistence over another. (shrink)

A presentation of the Lewis-Sider argument from vagueness for unrestricted composition and possible responses.

In this paper, I reply to Seidel’s objections against my argument from expert performance to the effect that arguments from expert opinion are weak arguments. I clarify what Seidel takes to be unclear points in my argument and show that it withstands Seidel’s objections.

In this paper, I argue that -- contrary to widely received opinion -- logical arguments from evil are well and truly alive and kicking.

Philosophers of perception are familiar with the argument from illusion, at least since Hume formulated it to challenge a naïve form of realism. In this paper, I present an analogous argument but in the domain of action. It focuses on slips, a common kind of mistake. But, otherwise, it is structurally similar. The argument challenges some contemporary views about the nature of action inspired by Wittgenstein. The discussion shows how thinking about these common mistakes helps illuminate (...) aspects of human agency that tend to be overlooked whenever too much emphasis is placed on the rationality of human actions.

According to Peter van Inwagen, C. S. Lewis failed in his attempt to undermine naturalism with his Argument from Reason. According to van Inwagen, Lewis provides no justification for his central premise, that naturalism is inconsistent with holding beliefs for reasons. What is worse, van Inwagen argues that the main premise in Lewis's argument from reason is false. We argue that it is not false. The defender of Lewis's argument can make use of the problem (...) of mental causal drainage, a longstanding issue in philosophy of mind, to show how van Inwagen's objection fails. (shrink)

The argument from reason states that if naturalism is true, then our beliefs are caused by physical processes rather than being causally based in their reasons, so our beliefs are not knowledge—including the belief in naturalism itself. Recent critics of the argument from reason provide dual process replies to the argument from reason—our beliefs can have both a naturalistic cause/ explanation and be caused/explained by its reasons, thereby showing that naturalism can accommodate knowledge. In (...) this paper I consider three dual process replies and conclude that none of them are successful. (shrink)

Attempts have been made to prove God's non-existence. Often this takes the form of an appeal to the so-called Argument from Evil: if God were to exist, then he would not permit as much suffering in the world as there actually is. Hence the fact that there is so much suffering constitutes evidence for God's non-existence. In this essay I propose a variation which I shall call ‘The Argument from Non-belief’. Its basic idea is that if (...) God were to exist, then he would not permit as much non-belief in the world as there actually is. Hence the fact that there is so much non-belief constitutes evidence for God's non-existence. (shrink)

This chapter will amount to a detailed exposition and exploration of one of the most prominent arguments against the existence of an unsurpassable world: the argument from addition. Endorsed by a variety of thinkers such as St. Thomas Aquinas, Alvin Plantinga, and William Rowe, the argument from addition uses the possibility of adding good things to a candidate unsurpassable world to argue that every world is surpassable. While widely endorsed, the argument has come under recent (...) criticism. By carefully working through a targeted version of the argument, I set out to establish the following: (i) that a world can always contain more good things; (ii) that a suitably restricted additive aggregation principle allows us to say that adding more good things in a certain way is an improvement, and (iii) that objections to the argument from widespread value incomparability fail.

This paper is concerned with a recent, clever, and novel argument for the need for genuine collectives in our ontology of agents to accommodate the kinds of normative judgments we make about them. The argument appears in a new paper by David Copp, "On the Agency of Certain Collective Entities: An Argument from 'Normative Autonomy'" (Midwest Studies in Philosophy: Shared Intentions and Collective Responsibility, XXX, 2006, pp. 194-221; henceforth ‘ACE’), and is developed in Copp’s paper for (...) this special journal issue, “The Collective Moral Autonomy Thesis” (henceforth ‘CAT’). The argument goes as follows. -/- (1) We correctly assign blame (or obligations) to collectives in circumstances in which it would be a mistake to assign any (relevantly related) blame (or obligations) to their members. (2) If (1), then collectives are genuine agents over and above their members. (3) Therefore, collectives are genuine agents over and above their members. -/- Following Copp, I call (1) the Collective Moral Autonomy Thesis (CMA). Copp argues for CMA primarily by appeal to cases, but also offers two general arguments for it. In the cases that Copp describes, we are to judge that a collective act is blameworthy, though each member of the group that acts is blameless because he is merely following procedures appropriate for his participation, or because there are excusing factors, or because of overriding personal duties. -/- I argue that the case for CMA has not been made. In particular, I argue that, in each case in which we feel inclined to hold a group responsible for something but not its members, it is because -/- 1. we have accepted a false dilemma, that when no one agent is fully responsible for the action of a group of which he is a member, the only entity that could be responsible is the group as such, or 2. we have directed our attention to the wrong individual or individuals, or 3. we have become confused about the commitments of the individuals, or 4. we have mistaken ameliorating for excusing factors, or 5. we have mistaken moral blameworthiness and all-in rational blameworthiness, or 6. a combination of these things.

In times of populist mistrust towards experts, it is important and the aim of the paper to ascertain the rationality of arguments from expert opinion and to reconstruct their rational foundations as well as to determine their limits. The foundational approach chosen is probabilistic. However, there are at least three correct probabilistic reconstructions of such argumentations: statistical inferences, Bayesian updating, and interpretive arguments. To solve this competition problem, the paper proposes a recourse to the arguments' justification strengths achievable in (...) the respective situation. (shrink)

Very broadly, an argument from collections is an argument that purports to show that our beliefs about sets imply — in some sense — the existence of God. Plantinga (2007) first sketched such an argument in “Two Dozen” and filled it out somewhat in his 2011 monograph Where the Conflict Really Lies: Religion, Science, and Naturalism. In this paper I reconstruct what strikes me as the most plausible version of Plantinga’s argument. While it is a (...) good argument in at least a fairly weak sense, it doesn’t initially appear to have any explanatory advantages over a non-theistic understanding of sets — what I call set theoretic realism. However, I go on to argue that the theist can avoid an important dilemma faced by the realist and, hence, that Plantinga’s argument from collections has explanatory advantages that realism does not have.

Consciousness is one of the most complex phenomena of the world. As philosophy of mind, together with psychology and cognitive sciences, developed, consciousness was seriously studied in the twentieth century. Many attempts have been made to explain the nature of this mysterious phenomenon and the way in which it has come into being; as a result, different theories have been offered about it. In this paper, a variety of naturalistic theories of consciousness have been considered, and their weakness has been (...) shown. (shrink)

Moral abolitionists claim that morality ought to be abolished. According to one of their most prominent arguments, this is because making moral judgments renders people significantly less tolerant toward anyone who holds divergent views. In this paper we investigate the hypothesis that morality’s tolerance-decreasing effect only occurs if people are realists about moral issues, i.e., they interpret these issues as objectively grounded. We found support for this hypothesis (Studies 1 and 2). Yet, it also turned out that the intolerance associated (...) with realism is mediated by moral conviction and perceived consensus. People tend to feel more strongly about those moral issues they ground objectively and, in doing so, are more prone to display the vice of moral smugness toward those who disagree with them. The remedy for this that has been recommended is humility which we found (Study 3) is indeed related to reduced intolerance, in part by predicting a reduction in realism, but also in part through a direct connection to intolerance. These results put pressure on abolitionists’ “argument from intolerance.”. (shrink)

Arguments from human dignity feature prominently in the Lethal Autonomous Weapons moral feasibility debate, even though their exists considerable controversy over their role and soundness and the notion of dignity remains under-defined. Drawing on the work of Dieter Birnbacher, I fix the sub-discourse as referring to the essential value of human persons in general, and to postulated moral rights of combatants not covered within the existing paradigm of the International Humanitarian Law in particular. I then review and critique dignity-based (...) arguments against LAWS: argument from faulty targeting process, argument from objectification, argument from underappreciation of the value of human life and the argument from the absence of mercy. I conclude that the argument from the absence of mercy is the only dignity-based argument that is both valid and irreducible to another class of arguments within the debate, and that it offers insufficient justification for a global ban on LAWS.

The much-discussed ‘Argument from Small Improvement’ has been advanced both as a reason to reject (tripartite) Completeness, one of the standard axioms of decision theory, and to accept the possibility of rationally incomparable choices. But this form of argument cannot be an effective basis for either of these conclusions, unless one already has some prior, independent reason to prefer Transitivity to Completeness as a constraint on rational preferences (or rational values). In particular, I show how a reverse (...) argument from small improvement can be constructed, starting from the assumption of tripartite Completeness, to the conclusion that Transitivity fails. I conclude that this form of argument as it has been standardly presented in the literature is a kind of ‘red herring’. We can only make progress here by evaluating the reasons independent of either such argument to prefer one or other of Transitivity or Completeness. (shrink)

For A. J. Ayer, the occurrence of delusions confutes the notion that we perceive the world directly. He argues instead that perceptions are caused by immaterial “sense data” which somehow represent the properties of material things to us in our experiences. J. L. Austin systematically rejects Ayer’s claims, arguing that the occurrence of delusions does not preclude the possibility of direct perception, and that, indeed, our normal perception is direct. I challenge both philosophers’ ideas by examining how they deal with (...) the phenomenon of colour. (shrink)

Arguments from Silence have been used many times in attempts to discredit the foundations of religions. In this project, I demonstrate how one might judge the epistemic value of such arguments. To begin, I lay out for examination a specific argument from silence given by Walter Richard Cassels in his work Supernatural Religion. I then discuss a recently developed Bayesian approach for dealing with arguments from silence. Finally, using Cassels’s work and the work of some of (...) the critics who replied to his argument, I argue for what probabilities might be applied in the use of the Bayesian method for testing the epistemic value Cassels’s argument and demonstrate how one might respond to similar arguments.

Humean arguments from evil are some of the most powerful arguments against Theism. They take as their data what we know about good and evil. And they argue that some rival to Theism better explains, or otherwise predicts, that data than Theism. However, this paper argues that there are many problems with various methods for defending Humean arguments. I consider Philo’s original strategy; modern strategies in terms of epistemic probability; phenomenological strategies; and strategies that appeal to scientific and metaphysical (...) explanations. None of these methods have been sufficiently developed to provide a clear and distinctive defense of Humean arguments. Defenders of Humean arguments need to spend more time on the underlying methodology of their arguments. (shrink)

While the existence of horrendous evils has generally been taken to be evidence against the existence of God, some philosophers have suggested that it may be evidence for the existence of God. This paper introduces three main kinds of theistic arguments from horrendous evils: the argument from objectively horrifying evils, the pragmatic argument from evil, and an argument from reasonable responses. For each of these arguments, I will first reconstruct a standard version of (...) the argument, before suggesting ways the argument may be challenged, or further developed. (shrink)

In this paper, we present what we call the argument from accidental truth, according to which some instances of deflationist schemata, even those carefully reformulated and adjusted by Field and Horwich to accommodate the truth of utterances, are falsified due to accidental truths. Since the folk concept of truth allows for accidental truths, the deflationary theory of truth will face a serious problem. In particular, it follows that the deflationist schema fails to capture the proper extension of truth (...) by precluding accidental truths of utterances. Even though the argument uses the contextualist cases, this conclusion does not require so much as the truth of contextualism, but only two assumptions, the existence of context-relative non-literal contents of utterances (or speech acts), and the existence of accidental truths, both of which are widely accepted by folks and theorists. We will also consider various responses to the argument, including the revisionary deflationist position, all of which we argue are unsatisfactory or committed to a highly implausible view. (shrink)

According to informal logic, the possibilities of deductive logic as a tool for analysing and evaluating ordinary arguments are very limited. While I agree with this claim in general, I question it in the case of the argument from cause to effect. In this paper I first show, on the basis of carefully chosen examples, that we usually react differently to falsification of the conclusion of the argument from cause to effect than we do to the (...) falsification of the conclusion of other defeasible arguments. I then identify general conditions and assumptions under which the causal argument from cause to effect can be reconstructed as deductive. Finally, I compare the causal argument with the expert argument, which is a typical example of a defeasible argument in the narrower sense. (shrink)

A number of authors have developed evidential arguments from evil in the past thirty years. Perhaps the best known evidential arguments from evil are those presented in Rowe (1979) and Draper (1989). We shall spend most of this chapter examining these two arguments.

It is argued that, contrary to prevailing opinion, Bas van Fraassen nowhere uses the argument from underdetermination in his argument for constructive empiricism. It is explained that van Fraassen’s use of the notion of empirical equivalence in The Scientific Image has been widely misunderstood. A reconstruction of the main arguments for constructive empiricism is offered, showing how the passages that have been taken to be part of an appeal to the argument from underdetermination should actually (...) be interpreted.

Many have said that God is hidden. This alleged hiddenness is particularly troublesome for evangelical Christianity, much more so than generally recognized, for it would render certain facts about the world and about the Bible very hard to explain on the hypothesis that the God of evangelical Christianity exists. Those facts would be best explained by appeal to the alternate hypothesis that that deity does not exist. Three evidential, epistemic, atheological arguments emerge from this consideration. One of them is (...) the Argument from Nonbelief, which focuses on the fact that there is widespread nonbelief in the given deity. I have written essays and a book (NONBELIEF & EVIL) on that one. The other two are the Argument from Confusion (to be labeled AC) and the Argument from Biblical Defects (ABD). AC focuses on the fact that there is widespread confusion among Christians regarding important doctrinal issues, including morality and salvation. ABD focuses on the fact that there are various defects in the Bible. The present essay is devoted to the latter two arguments. (shrink)

Do we rightly expect a perfectly loving God to bring it about that, right now, we reasonably believe that He exists? It seems so. For love at its best desires the well-being of the beloved, not from a distance, but up close, explicitly participating in her life in a personal fashion, allowing her to draw from that relationship what she may need to flourish. But why suppose that we would be significantly better off were God to engage in (...) an explicit, personal relationship with us? Well, first, there would be broadly moral benefits. We would be able to draw on the resources of that relationship to overcome seemingly everpresent flaws in our character. And we would be more likely to emulate the self-giving love with which we were loved. So loved, we would be more likely to flourish as human beings. Secondly, there would be experiential benefits. We would be, for example, more likely to experience peace and joy stemming from the strong conviction that we were properly related to our Maker, security in suffering knowing that, ultimately, all shall be well, and there would be the sheer pleasure of God's loving presence. As a consequence of these moral and experiential benefits, our relationships with others would likely improve. Thirdly, to be personally related to God is intrinsically valuable, indeed, according to the Christian tradition, the greatest intrinsic good. In these ways our well-being would be enhanced if God were to relate personally to us. Moreover, the best love does not seek a personal relationship only for the sake of the beloved. As Robert Adams rightly notes, "It is an abuse of the word 'love' to say that one loves a person, or any other object, if one does not care, except instrumentally, about one's relation to that object."1 Thus, God would want a personal relationship with us not only for the benefit we would receive from it but for its own sake as well. So, if a perfectly loving God exists, He wants a personal relationship with us, or more accurately, every capable creature, those cognitively and affectively equipped to relate personally with Him..

In his well-known essay on Wittgenstein, Saul Kripke maintains that dispositional analyses of meaning cannot work mainly because the concept of disposition is descriptive, whereas that of meaning is normative. Unfortunately, neither Kripke nor his followers have ever spelled out this “argument from normativity” in full detail. As a result, the argument does not have good press. This paper offers an explicit version of the argument. In particular, (1) I try to explain what the claim that (...) meaning is normative amounts to, (2) I try to clarify what supports it, and (3) I sketch a valid version of the argument. (shrink)

In the article, first I present the atheistic argument from pointless evil and the argument from chance. The essence of the argument from chance consists in the incompatibility of the existence of purposeless events and the existence of a God who planned the universe to the last detail. Second, I would like to show that there is a relation between the evidential argument from evil and the argument from chance. An (...) analysis of the theistic argument from small probabilities is a helpful starting point for the presentation of how the two arguments are related. (shrink)

Revisionary ontologists are making a comeback. Quasi-nihilists, like Peter van Inwagen and Trenton Merricks, insist that the only composite objects that exist are living things. Unrestriced universalists, like W.V.O. Quine, David Lewis, Mark Heller, and Hud Hudson, insist that any collection of objects composes something, no matter how scattered over time and space they may be. And there are more besides. The result, says Eli Hirsch, is that many commonsense judgments about the existence or identity of highly visible physical objects (...) are a priori necessarily false. In a “last ditch effort” to bring revisionary ontologists back to their senses, Hirsch marshalls what he calls the Argument from Charity. We can be sure that there are tables and chairs and that there are no fusions of Plato’s nose and the Eiffel Tower, says Hirsch, because these commonsense platitudes are a logical consequence of the well-known principle of interpretive charity applied to natural languages, like English. In what follows, I assess the Argument from Charity. My conclusion is that if this is the best we can do to save revisionary ontologists, they are surely lost forever. (shrink)

Van Fraassen infers the truth of the contextual theory from his observation that it has passed a crucial test. Mizrahi infers the comparative truth of our best theories from his observation that they are more successful than their competitors. Their inferences require, according to the argument from double spaces, the prior belief that it is more likely that their target theories were pulled out from the T-space than from the O-space. The T-space is the (...) logical space of unconceived theories whose appearances agree with their realities; the O-space is the logical space of unconceived theories whose appearances may agree or disagree with their realities.

Dombrowski and Murdoch offer versions of the ontological argument which aim to avoid two types of objection – those concerned with the nature of the divine, and those concerned with the move from an abstract concept to a mind-independent reality. For both, the nature of the concept of God/Good entails its instantiation, and both supply a supporting argument from experience. It is only Murdoch who successfully negotiates the transition from an abstract concept to the instantiation (...) of that concept, however, and this is achieved by means of an ontological argument from moral experience which, in a reversal of the Kantian doctrine, depends ultimately on a form of the cosmological argument.

It has long been known that brain damage has important negative effects on one’s mental life and even eliminates one’s ability to have certain conscious experiences. It thus stands to reason that when all of one’s brain activity ceases upon death, consciousness is no longer possible and so neither is an afterlife. It seems clear that human consciousness is dependent upon functioning brains. This essay reviews some of the overall neurological evidence from brain damage studies and concludes that our (...) argument from brain damage has been vindicated by such overwhelming evidence. It also puts forth a more mature philosophical rationale against an afterlife and counters several replies to the argument. -/- 1. Philosophical Background -- 2.

One of the premises of the argument from design is the need for the order of a designer. This premise has been explained in various ways, one of which is the calculus of probabilities. It posits that the likelihood of an ordered thing coming into existence by chance is so low that human beings consider it nearly impossible; therefore, this order requires an intelligent designer. However, some contemporary Muslim philosophers, such as Ayatollah Jawādī Āmulī, along with certain Western (...) philosophers, have contested the validity of the calculus of probabilities. They argue that the calculus of probabilities does not reveal reality but is merely practically useful. They assert that undesigned states have the same probability as designed states. In this article, I address these objections, refute them, and ultimately demonstrate the soundness of the argument from design based on the calculus of probabilities. (shrink)

Some philosophers have argued that the paucity of evidence for theism — along with basic assumptions about God's nature — is ipso facto evidence for atheism. The resulting argument has come to be known as the argument from divine hiddenness. Theists have challenged both the major and minor premises of the argument by offering defences. However, all of the major, contemporary defences are failures. What unites these failures is instructive: each is implausible given other commitments shared (...) by everyone in the debate or by theists in particular. Only challenges which are plausible given both common sense and other theistic commitments will undermine the argument from divine hiddenness. Given that such defences universally fail, the best hope for a successful challenge to the argument comes from more general sceptical responses. This sort of response is briefly sketched and defended against four independent objections. (shrink)

Sider (2011, 2013) proposes a reductive analysis of metaphysical modality—‘(modal) Humeanism’—and goes on to argue that it has interesting epistemological and methodological implications. In particular, Humeanism is supposed to undermine a class of ‘arguments from possibility’, which includes Sider's (1993) own argument against mereological nihilism and Chalmers's (1996) argument against physicalism. I argue that Sider's arguments do not go through, and moreover that we should instead expect Humeanism to be compatible with the practice of arguing from (...) possibility in philosophy. (shrink)

In this essay for a PPR book symposium on Theodore Sider's _Four-Dimensionalism<D>, I focus on two of Sider's arguments for four-dimensionalism: (i) his argument from vagueness, and (ii) his argument from time travel. Concerning (i), I first show that Sider's argument commits him to certain strange consequences that many four-dimensionalists may not endorse, and then I discuss an objection that involves appealing to 'brutal composition', the view that there is no informative answer to Peter van (...) Inwagen's 'special composition question'. Concerning (ii), I argue that the three-dimensionalist can account for time travel scenarios in a way that is analogous to Sider's four-dimensionalist account of such scenarios. (shrink)

I argue that the best interpretation of the general theory of relativity has need of a causal entity, and causal structure that is not reducible to light cone structure. I suggest that this causal interpretation of GTR helps defeat a key premise in one of the most popular arguments for causal reductionism, viz., the argument from physics.

This article explores the relationship between epistemic relativism and Pyrrhonian scepticism. It is argued that a fundamental argument for contemporary epistemic relativism derives from the Pyrrhonian problem of the criterion. Pyrrhonian scepticism is compared and contrasted with Cartesian scepticism about the external world and Humean scepticism about induction. Epistemic relativism is characterized as relativism due to the variation of epistemic norms, and is contrasted with other forms of cognitive relativism, such as truth relativism, conceptual relativism and ontological relativism. (...) An argument from the Pyrrhonian problem of the criterion to epistemic relativism is presented, and is contrasted with three other arguments for epistemic relativism. It is argued that the argument from the criterion is the most fundamental argument for epistemic relativism. Finally, it is noted how the argument of the present paper fits with the author’s previous suggestion that a particularist response to the Pyrrhonian sceptic may be combined with a naturalistic view of epistemic warrant to meet the challenge of epistemic relativism.

Some versions of the doctrine of divine simplicity imply that God lacks really differentiated parts. I present a new argument against these views based on divine beauty. The argument proceeds as follows: God is beautiful. If God is beautiful, then this beauty arises from some structure. If God’s beauty arises from a structure, then God possesses really differentiated parts. If these premises are true, then divine simplicity is false. I argue for each of the argument’s (...) premises and defend it against objections, including an objection based on analogical predication, and an objection that supposes that God is simple while appearing complex.

In his recent book Error Theory: History, Critique, Defence, Jonas Olson attempts to revive the argument from queerness originally made famous by J.L. Mackie. In this paper, we do three things. First, we eliminate four untenable formulations of the argument. Second, we argue that the most plausible formulation is one that depends crucially upon considerations of parsimony. Finally, we evaluate this formulation of the argument. We conclude that it is unproblematic for proponents of moral non-naturalism—the target (...) of the argument from queerness. (shrink)

Arguments from disagreement against moral realism begin by calling attention to widespread, fundamental moral disagreement among a certain group of people. Then, some skeptical or anti-realist-friendly conclusion is drawn. Chapter 2 proposes that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least one of its premises casts doubt either on itself or on one of the other premises. On (...) reflection, this shouldn’t be surprising. These arguments are intended to support very strong metaphysical or epistemological conclusions about morality. They must therefore employ very strong metaphysical or epistemological premises. But, given the pervasiveness of disagreement in philosophy, especially about metaphysics and epistemology, very strong premises are virtually certain to be the subject of widespread, intractable disagreement—precisely the sort of disagreement that proponents of these arguments think undermine moral claims. Thus, these arguments undermine their own premises. If Chapter 2’s argument is sound, it provides realists with a single, unified strategy for responding to any existing or forthcoming arguments from disagreement. (shrink)

In his Pyrrhonian Outlines , Sextus Empiricus employs an argument based upon the possibility of disagreement in order to show that one should not assent to a Dogmatic claim to which at present one cannot oppose a rival claim. The use of this argument seems to be at variance with the Pyrrhonian stance, both because it does not seem to accord with the definition of Skepticism and because the argument appears to entail that the search for truth (...) is doomed to failure. In the present paper, I examine the passages in which Sextus utilizes the argument from possible disagreement and offer an interpretation that makes the use of this argument compatible with the Pyrrhonian outlook.

The author puts forward and defends a new argument for indirect realism called the argument from pain. The argument is akin to a well-known traditional argument to the same end, the argument from hallucination. Like the latter, it contains one premise stating an analogy between veridical perceptions and certain other states and one premise stating that those states are states of acquaintance with sense-data. The crucial difference is that the states that are said (...) to be analogous to veridical perceptions are pain-states instead of hallucinations. This difference makes the argument from pain immune to the standard objections against the argument from hallucination. (shrink)
