According to First-Person Realism, one's own first-person perspective on the world is metaphysically privileged in some way. After clarifying First-Person Realism by reference to parallel debates in the metaphysics of modality and time, I survey eight different arguments in favor of First-Person Realism.

Our universe seems to be miraculously fine-tuned for life. Multiverse theories have been proposed as an explanation for this on the basis of probabilistic arguments, but various authors have objected that we should consider our total evidence that this universe in particular has life in our inference, which would block the argument. The debate thus crucially hinges on how Bayesian background and evidence are distinguished and on how indexical or demonstrative terms are analysed. The aim of this article is (...) to take a step back and examine these various aspects of Bayesian reasoning and how they affect the arguments. The upshot is that there are reasons to resist the fine-tuning argument for the multiverse, but the "this-universe-objection" is not one of them. (shrink)

Evolutionary debunking arguments are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is (...) incompatible with a parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.

In this crisply written book, Hanno Sauer offers the first book-length treatment of debunking arguments in ethics, developing an empirically informed and philosophically sophisticated account of genealogical arguments and their significance for the reliability of moral cognition. He breaks new ground by introducing a series of novel distinctions into the current debate, which allows him to develop a framework for assessing the prospects of debunking or vindicating our moral intuitions. He also challenges the justification of some of our (...) moral judgments by showing that they are based on epistemically defective processes. His book is an original, cutting-edge contribution to the burgeoning field of empirically informed metaethics, and will interest philosophers, psychologists, and anyone interested in how - and whether - moral judgment works.

This is a short introduction to ontological arguments. It begins with a brief characterization of ontological arguments that proceeds mainly by way of example. The rest of the discussion is given over to consideration of what looks like a very simple ontological argument. This consideration turns up many of the issues that arise when more complex ontological arguments are examined.

Does the morality of abortion depend on the moral status of the human fetus? Must the law of abortion presume an answer to the question of when personhood begins? Can a law which permits late abortion but not infanticide be morally justified? These are just some of the questions this book sets out to address. With an extended analysis of the moral and legal status of abortion, Kate Greasley offers an alternative account to the reputable arguments of Ronald Dworkin (...) and Judith Jarvis Thomson and instead brings the philosophical notion of 'personhood' to the foreground of this debate. Structured in three parts, the book will consider the relevance of prenatal personhood for the moral and legal evaluation of abortion; trace the key features of the conventional debate about when personhood begins and explore the most prominent issues in abortion ethics literature: the human equality problem and the difference between abortion and infanticide; and examine abortion law and regulation as well as the differing attitudes to selective abortion. The book concludes with a snapshot into the current controversy surrounding the scope of the right to conscientiously object to participation in abortion provision. (shrink)

On doxastic theories of propositional faith,necessarily,S has faith that p only if S believes that p. On nondoxastic theories of propositional faith, it’s false that,necessarily,S has faith that p only if S believes that p. In this article, I defend three arguments for nondoxastic theories of faith and I respond to published criticisms of them.

Experimental philosophers have challenged friends of the expertise defense to show that the intuitive judgments of professional philosophers are different from the intuitive judgments of nonphilosophers, and the intuitive judgments of professional philosophers are better than the intuitive judgments of nonphilosophers, in ways that are relevant to the truth or falsity of such judgments. Friends of the expertise defense have responded by arguing that the burden of proof lies with experimental philosophers. This article sketches three arguments which show that (...) both and are probably false. If its arguments are cogent, then shifting the burden of proof is a futile move, since philosophical training makes no difference so far as making intuitive judgments in response to hypothetical cases is concerned.

Now in its Eighth Edition, UNDERSTANDING ARGUMENTS: AN INTRODUCTION TO INFORMAL LOGIC, 8th Edition. has proven itself to be an exceptional guide to understanding and constructing arguments in the context of students' academic studies as well as their subsequent professional careers. Its tried and true strengths include multiple approaches to the analysis of arguments; a thorough grounding on the uses of language in everyday discourse; and chapters in the latter half of the book that apply abstract concepts (...) to concrete legal, moral, and scientific issues.

Robert Stern investigates how scepticism can be countered by using transcendental arguments concerning the necessary conditions for the possibility of experience, language, or thought. He shows that the most damaging sceptical questions concern neither the certainty of our beliefs nor the reliability of our belief-forming methods, but rather how we can justify our beliefs.

Fourteen new essays by a distinguished team of authors offer a broad and stimulating re-examination of transcendental arguments. This is the philosophical method of arguing that what is doubted or denied by the opponent must be the case, as a condition for the possibility of experience, language, or thought.The line-up of contributors features leading figures in the field from both sides of the Atlantic; they discuss the nature of transcendental arguments, and consider their role and value. In particular, (...) they consider how successful such arguments are as a response to sceptical problems. The editor's introduction provides historical context and philosophical orientation for the discussions. This is the first major appraisal of transcendental arguments since the 1970s; they have continued to play a significant role in philosophy, and recent developments in epistemology and metaphysics have raised new questions and challenges for them. Transcendental Arguments will be essential reading for anyone interested in this area of philosophy, and the starting-point for future work. (shrink)

This is the sequel to my “Fifteen Arguments Against Finite Frequentism” ( Erkenntnis 1997), the second half of a long paper that attacks the two main forms of frequentism about probability. Hypothetical frequentism asserts: The probability of an attribute A in a reference class B is p iff the limit of the relative frequency of A ’s among the B ’s would be p if there were an infinite sequence of B ’s. I offer fifteen arguments against this (...) analysis. I consider various frequentist responses, which I argue ultimately fail. I end with a positive proposal of my own, ‘hyper-hypothetical frequentism’, which I argue avoids several of the problems with hypothetical frequentism. It identifies probability with relative frequency in a hyperfinite sequence of trials. However, I argue that this account also fails, and that the prospects for frequentism are dim. (shrink)

What can be said in favor of consuming animal products? This chapter surveys the options, with special focus on it attempts to exploit pro-vegan principles for anti-vegan ends. Utilitarian, rights-based, contractualist, and agrarian proposals are explored, as well as some recent arguments that attempt to revive a form of speciesism. Ultimately, the chapter considers how such arguments might inform a broad case for consuming animal products—that is, one that might earn respect from those in a variety of moral (...) camps—and it suggests that there may be good reasons to eat roadkill, bugs, bivalves, in vitro meat, animal products that will be wasted, and the bodies and byproducts of animals that live full, pleasant lives.

In this paper I try to show that semantics can explain word-to-world relations and that sentences can have meanings that determine truth-conditions. Critics like Chomsky typically maintain that only speakers denote, i.e., only speakers, by using words in one way or another, represent entities or events in the world. However, according to their view, individual acts of denotations are not explained just by virtue of speakers’ semantic knowledge. Against this view, I will hold that, in the typical cases considered, semantic (...) knowledge can account for the denotational uses of words of individual speakers. (shrink)

In the recent philosophical literature, several counterexamples to the interpretative principle that symmetry-related models are physically equivalent have been suggested The Oxford handbook of philosophy of physics, Oxford University Press, Oxford, 2013, Noûs 52:946–981, 2018; Fletcher in Found Phys 50:228–249, 2020). Arguments based on these counterexamples can be understood as arguments from scientific practice of roughly the following form: because in scientific practice such-and-such symmetry-related models are treated as representing distinct physical situations, these models indeed represent distinct physical (...) situations. In this paper, a strategy for analysing arguments of this type is presented and applied to the examples that can be found in the literature. I argue that if we are exclusively interested in models understood as representing entire possible worlds, arguments from scientific practice should involve some additional assumptions to guarantee they are relevant for models understood in this way. However, none of the examples presented in the literature satisfy all these additional assumptions, which leads to the conclusion that arguments from scientific practice based on these examples do not undermine the interpretative principle that different symmetry-related models represent the same possible world.

An exchange between Patrick Grim and Alvin Plantinga regarding Cantorian arguments against the possibility of an omniscient being.

In this paper, I argue that arguments from expert opinion, i.e., inferences from “Expert E says that p” to “p,” where the truth value of p is unknown, are weak arguments. A weak argument is an argument in which the premises, even if true, provide weak support—or no support at all—for the conclusion. Such arguments from expert opinion are weak arguments unless the fact that an expert says that p makes p significantly more likely to be (...) true. However, research on expertise shows that expert opinions are only slightly more accurate than chance and much less accurate than decision procedures. If this is correct, then it follows that arguments from expert opinion are weak arguments. (shrink)

Data from medical research are typically summarized with various types of outcome measures. We present three arguments in favor of absolute over relative outcome measures. The first argument is from cognitive bias: relative measures promote the reference class fallacy and the overestimation of treatment effectiveness. The second argument is decision-theoretic: absolute measures are superior to relative measures for making a decision between interventions. The third argument is causal: interpreted as measures of causal strength, absolute measures satisfy a set of (...) desirable properties, but relative measures do not. Absolute outcome measures outperform relative measures on all counts. (shrink)

Walton gives a clear method for analyzing and evaluating cases of ad hominem arguments found in everyday argumentation.

When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on the natural have (...) also been influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.

A probability distribution is regular if it does not assign probability zero to any possible event. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson and Benci et al. have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson’s “isomorphic” events are not in fact isomorphic, but Howson (...) is speaking of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson’s physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not. They are founded on the premise that similar events should have the same probability in the same model, or in one case, on the assumption that a single rotation-invariant distribution is possible. Having failed to refute the symmetry arguments on such technical grounds, one could deny their implicit premises, which is a heavy cost, or adopt varying degrees of instrumentalism or pluralism about regularity, but that would not serve the project of accurately modelling chances.

The aim of this article is to identify the strongest evolutionary debunking argument against moral realism and to assess on which empirical assumptions it relies. In the recent metaethical literature, several authors have de-emphasized the evolutionary component of EDAs against moral realism: presumably, the success or failure of these arguments is largely orthogonal to empirical issues. I argue that this claim is mistaken. First, I point out that Sharon Street’s and Michael Ruse’s EDAs both involve substantive claims about the (...) evolution of our moral judgments. Next, I argue that combining their respective evolutionary claims can help debunkers to make the best empirical case against moral realism. Some realists have argued that the very attempt to explain the contents of our endorsed moral judgments in evolutionary terms is misguided, and have sought to escape EDAs by denying their evolutionary premise. But realists who pursue this reply can still be challenged on empirical grounds: debunkers may argue that the best, scientifically informed historical explanations of our moral endorsements do not involve an appeal to mind-independent truths. I conclude, therefore, that the empirical considerations relevant for the strongest empirically driven argument against moral realism go beyond the strictly evolutionary realm; debunkers are best advised to draw upon other sources of genealogical knowledge as well.

A probability distribution is regular if no possible event is assigned probability zero. While some hold that probabilities should always be regular, three counter-arguments have been posed based on examples where, if regularity holds, then perfectly similar events must have different probabilities. Howson (2017) and Benci et al. (2016) have raised technical objections to these symmetry arguments, but we see here that their objections fail. Howson says that Williamson’s (2007) “isomorphic” events are not in fact isomorphic, but Howson (...) is speaking of set-theoretic representations of events in a probability model. While those sets are not isomorphic, Williamson’s physical events are, in the relevant sense. Benci et al. claim that all three arguments rest on a conflation of different models, but they do not.

In this book, Daniel Cohen explores the connections between arguments and metaphors, most pronounced in philosophy because philosophical discourse is both thoroughly metaphorical and replete with argumentation. Cohen covers the nature of arguments, their modes and structures, and the principles of their evaluation, and addresses the nature of metaphors, their place in language and thought, and their connections to arguments, identifying and reconciling arguments' and metaphors' respective roles in philosophy.

One recently popular strategy for avoiding the moral error theory is via a ‘companions in guilt’ argument. I focus on those recently popular arguments that take epistemic facts as a companion in guilt for moral facts. I claim that there is an internal tension between the two main premises of these arguments. It is a consequence of this that either the soundness or the dialectical force of the companions in guilt argument is undermined. I defend this claim via (...) (i) analogy with philosophical debates concerning the indispensability of mathematical objects to natural science, and (ii) discussion of the ‘entanglement’ of epistemic concepts and moral concepts in deliberation. I conclude by proposing a positive view of what kind of argument must be used if moral error theories are to be successfully undermined. (shrink)

I discuss the structure of genealogical debunking arguments. I argue that they undermine our mathematical beliefs if they undermine our moral beliefs. The contrary appearance stems from a confusion of arithmetic truths with (first-order) logical truths, or from a confusion of reliability with justification. I conclude with a discussion of the cogency of debunking arguments, in light of the above. Their cogency depends on whether information can undermine all of our beliefs of a kind, F, without giving us (...) direct reason to doubt that our F-beliefs are modally secure. (shrink)

This article is about relations of support and conflict within systems of fundamental legal rights—and the arguments for and against rights that those relations make possible. Justificatory linkage arguments defend controversial rights by claiming that they provide very useful support to the realisation of well-accepted rights. This article analyses such arguments in detail and discusses their structures, uses and pitfalls. It then shows that linkage arguments can be used not just to defend rights, but also to (...) attack them. When rights conflict—whether severely or weakly, logically or practically—negative linkage arguments attacking them can be based on the trouble they make for other rights. Many examples of conflicts of rights are provided. Negative linkage arguments provide reasons for rejecting, repealing or trimming the criticised right. Such arguments are already in regular use, but their c. (shrink)

This entry addresses the question of group minds, by focusing specifically on empirical arguments for group cognition and group cognitive states. Two kinds of positive argument are presented and critically evaluated: the argument from individually unintended effects and the argument from functional similarity. A general argument against group cognition – which appeals to Occam’s razor – is also discussed. In the end, much turns on the identification of a mark of the cognitive; proposed marks are briefly surveyed in the (...) final section. (shrink)

According to haecceitism, some maximal possibilities differ even while they are qualitatively indiscernible. Since haecceitism is a modal thesis, it is typically defended by appeal to conceivability arguments. These arguments require us to conceive of qualitatively indiscernible possibilities that differ only with respect to the identity of the individuals involved. This paper examines a series of conceivability arguments for haecceitism and a variety of anti-haecceitist responses. It concludes that there is no irresistible conceivability argument for haecceitism even (...) while anti-haecceitist responses do come with certain notable commitments. (shrink)
