Radical Interpretation and Logical Pluralism

I examine Quine’s and Davidson’s arguments to the effect that classical logic is the one and only correct logic. This conclusion is drawn from their views on radical translation and interpretation, respectively. I focus on the latter, but I first address, independently, Quine’s argument to the effect that the ‘deviant’ logician, who departs from classical logic, is merely changing the subject. Regarding logical pluralism, the question is whether there is more than one correct logic. I argue that bivalence may be subject matter dependent, but that distribution and the law of excluded middle can probably not be dropped whilst maintaining the standard meanings of the connectives. In discussing the ramifications of the indeterminacy of interpretation, I ask whether it forces Davidsonian interpreters to adopt Dummett’s epistemic conception of truth vis-à-vis their interpretations. And, if so, does this cohere with their attributing a nonepistemic notion of truth to their interpretees? This would be a form of logical pluralism. In addition, I discuss Davidson’s arguments against conceptual schemes. Schemes incommensurable with our own could be construed as wholesale deviant logics, or so I argue. And, if so, their possibility would yield, in turn, the possibility of a radical logical pluralism. I also address Davidson’s application of Tarski’s definition of truth.

     

SUPERVALUATION FIXED-POINT LOGICS OF TRUTH

Michael Kremer defines fixed-point logics of truth based on Saul Kripke’s fixed point semantics for languages expressing their own truth concepts. Kremer axiomatizes the strong Kleene fixed-point logic of truth and the weak Kleene fixed-point logic of truth, but leaves the axiomatizability question open for the supervaluation fixed-point logic of truth and its variants. We show that the principal supervaluation fixed point logic of truth, when thought of as consequence relation, is highly complex: it is not even analytic. We also consider variants, engendered by a stronger notion of ‘fixed point’, and by variant supervaluation schemes. A ‘logic’ is often thought of, not as a consequence relation, but as a set of sentences – the sentences true on each interpretation. We axiomatize the supervaluation fixed-point logics so conceived.     

Kierkegaard’s Regulative Sacrifice: A Post-Kantian Reading of Fear and Trembling

Abstract

The present paper suggests to consider Kierkegaard’s use of Abraham’s story in Fear and Trembling in regulative terms, that is, to consider it as a model – not for our moral behaviour but rather for our religious behaviour. To do so, I first rely on recent literature to argue that Kierkegaard should be regarded as a distinctively post-Kantian philosopher: namely, a philosopher who goes beyond Kant in a way that is nevertheless true to the spirit of Kant’s original critical philosophy. Then, I present a post-Kantian reading of Fear and Trembling, focusing on the problematic implications that result from comparing this text with Hegel’s theory of recognition. Finally, I submit that sacrifice in Fear and Trembling is a regulative notion in a Kantian sense. This interpretation addresses some of the most problematic aspects of the text. I conclude that the regulativity of sacrifice may be regarded as an important and perhaps an essential component of Kierkegaard’s overall philosophical strategy.     

Nietzsche on the Nature of the Unconscious

Abstract

This paper argues that Nietzsche develops a novel and compelling account of the distinction between conscious and unconscious mental states: he argues that conscious mental states are those with conceptual content, whereas unconscious mental states are those with nonconceptual content. I show that Nietzsche’s puzzling claim that consciousness is ‘superficial’ and ‘falsifying’ can be given a straightforward explanation if we accept this understanding of the conscious/unconscious distinction. I originally defended this view in my ‘Nietzsche’s Theory of Mind: Consciousness and Conceptualization’ (2005, European Journal of Philosophy 13: 1–31); since then, the view has come under criticism on several fronts. Brian Leiter and others suggest that there is not enough textual evidence for the view. In addition, Leiter, Mattia Riccardi and Tsarina Doyle argue that, rather than aligning the conscious/unconscious distinction with the conceptual/nonconceptual distinction, Nietzsche endorses a higher-order thought model of consciousness. Riccardi also objects that Nietzsche must treat some unconscious mental states as conceptual. In this essay, I defend the interpretation in light of these objections. I provide new textual evidence for the interpretation, show that Nietzsche extracted aspects of the view from Schopenhauer’s work on consciousness, consider the possibility that Nietzsche endorses a higher-order thought theory, and respond to Riccardi’s objection.     

ON DAVIDSON'S REFUTATION OF CONCEPTUAL SCHEMES AND CONCEPTUAL RELATIVISM

Despite Donald Davidson's influential criticism of the very notion of conceptual schemes, the notion continues enjoying its popularity in contemporary philosophy and, accordingly, conceptual relativism is still very much alive. There is one major reason responsible for Davidson's failure which has not been widely recognized: What Davidson attacks fiercely is not the very notion , but a notion of conceptual schemes, namely, the Quinean notion of conceptual schemes and its underlying Kantian scheme-content dualism. However, such a notion simply cannot carry the weight of conceptual relativism for it does not catch the essences of conceptual relativism. Consequently, I argue that the very notion of conceptual schemes and conceptual relativism have survived Davidson's attack. Therefore, the failure of the Quinean notion of conceptual schemes and Kantian scheme-content dualism, even if Davidson can claim victory, does not mark the end of the very notion of conceptual schemes.     

Formal analyticity

In this paper, I introduce and defend a notion of analyticity for formal languages. I first uncover a crucial flaw in Timothy Williamson’s famous argument template against analyticity, when it is applied to sentences of formal mathematical languages. Williamson’s argument targets the popular idea that a necessary condition for analyticity is that whoever understands an analytic sentence assents to it. Williamson argues that for any given candidate analytic sentence, there can be people who understand that sentence and yet who fail to assent to it. I argue that, on the most natural understanding of the notion of assent when it is applied to sentences of formal mathematical languages, Williamson’s argument fails. Formal analyticity is the notion of analyticity that is based on this natural understanding of assent. I go on to develop the notion of formal analyticity and defend the claim that there are formally analytic sentences and rules of inference. I conclude by showing the potential payoffs of recognizing formal analyticity.     

Abstract Artifacts in Pretence

Abstract

In this paper I criticise a recent account of fictional discourse proposed by Nathan Salmon. Salmon invokes abstract artifacts as the referents of fictional names in both object- and meta-fictional discourse alike. He then invokes a theory of pretence to forge the requisite connection between object-fictional sentences and meta-fictional sentences, in virtue of which the latter can be assigned appropriate truth-values. I argue that Salmon's account of pretence renders his appeal to abstract artifacts as the referents of fictional names in object-fictional discourse explanatorily redundant. I further argue that his account is therefore no improvement over those he criticises, thus leaving his own account unmotivated.     

A Parsons Tale: Tractarian Reflections on a Semantical Paradox

According to Charles Parsons, a liar sentence does not express a proposition at the level of its primary use but does at the level where it is subjected to semantic interpretation. Thus, richer ontological resources unavailable at the level of primary use are available at the level of interpretation. In response to the objection that the correct semantic interpretation of a liar sentence is thereby distorted, I explain how Wittgenstein’s repudiation of “logical objects” and the Tractarian notion of an intrinsically iterative operation show that the liar sentence’s primary use anticipates but does not presuppose the richer interpretive ontology.     

Naturalism and the Space of Reasons in Mind and World

Abstract

This paper aims to show that many criticisms of McDowell’s naturalism of second nature are based on what I call ‘the orthodox interpretation’ of McDowell’s naturalism. The orthodox interpretation is, however, a misinterpretation, which results from the fact that the phrase ‘the space of reasons’ is used equivocally by McDowell in Mind and World. Failing to distinguish two senses of ‘the space of reasons’, I argue that the orthodox interpretation renders McDowell’s naturalism inconsistent with McDowell’s Hegelian thesis that the conceptual is unbounded. My interpretation saves McDowell from being inconsistent. However, the upshot of my interpretation is that what is really at work in McDowell’s diagnosis of the dualism between nature and reason is the Hegelian thesis, not the naturalism of second nature.     

Was Schopenhauer a Kantian Ethicist?

ABSTRACT

Commentators have generally seen the compassionate person as a second-rate character vis-à-vis the ascetic ‘saint’ who denies the will-to-life and resigns from willing altogether in Schopenhauer's ethical thought. In this paper I offer another way to interpret Schopenhauer’s ethics of compassion, which is textually grounded and genuinely Schopenhauerian, but which draws out similarities to Kant’s ethics that, I shall argue, have not been hitherto appreciated. Once these Kantian similarities are appreciated one sees that the compassionate person is no longer a runner up ethically and epistemically to the saint, rather, the compassionate person and the saint are at odds with each other, and really represent – unbeknownst to Schopenhauer himself–two distinct and incompatible ethical ideals.

To motivate this interpretation, I will first delineate the traditional interpretation of what Schopenhauer means by the compassionate person’s intuitive insight into the way the world really is. Second, I will offer a novel, and to my mind, textually preferable reading of what this intuitive insight consists in. Finally, I’ll suggest in light of recent work in metaethics by Colin Marshall – notably in his 2018 book titled Compassionate Moral Realism–that my interpretation of Schopenhauer’s ethics offers a creditable moral realist option for the contemporary landscape.     

Mereology in Aristotle's Assertoric Syllogistic

How does Aristotle think about sentences like ‘Every x is y’ in the Prior Analytics? A recently popular answer conceives of these sentences as expressing a mereological relationship between x and y: the sentence is true just in case x is, in some sense, a part of y. I argue that the motivations for this interpretation have so far not been compelling. I provide a new justification for the mereological interpretation. First, I prove a very general algebraic soundness and completeness result that unifies the most important soundness and completeness results to date. Then I argue that this result vindicates the mereological interpretation. In contrast to previous interpretations, this argument shows how Aristotle's conception of predication in mereological terms can do important logical work.     

Buridan's Solution to the Liar Paradox

Jean Buridan has offered a solution to the Liar Paradox, i.e. to the problem of assigning a truth-value to the sentence ‘What I am saying is false’. It has been argued that either (1) this solution is ad hoc since it would only apply to self-referencing sentences [Read, S. 2002. ‘The Liar Paradox from John Buridan back to Thomas Bradwardine’, Vivarium, 40 (2), 189–218] or else (2) it weakens his theory of truth, making his ‘a logic without truth’ [Klima, G. 2008. ‘Logic without truth: Buridan on the Liar’, in S. Rahman, T. Tulenheimo and E. Genot, Unity, Truth and the Liar: The Modern Relevance of Medieval Solutions to the Liar Paradox, Berlin: Springer, 87–112 (Chapter 5); Dutilh Novaes, C. 2011. ‘Lessons on truth from mediaeval solutions to the Liar Paradox’, The Philosophical Quarterly, 61 (242), 58–78]. Against (1), I will argue that Buridan's solution by means of truth by supposition does not involve new principles. Self-referential sentences force us to handle supposition more carefully, which does not warrant the accusation of adhoccery. I will also argue, against (2), that it is exaggerated to assert that this solution leads to a ‘weakened’ theory of truth, since it is consistent with other passages of the Sophismata, which only gives necessary conditions for the truth of affirmative propositions, but sufficient conditions for falsity.     

Mill on Happiness

Abstract

In this paper, I argue against the standard interpretation of Mill as a hedonistic utilitarian, and argue instead that Mill holds a ‘eudaimonic’ conception of happiness. I begin by clarifying exactly what I mean by a eudaimonic conception of happiness, and then examine the textual evidence for this eudaimonic interpretation, as well as the evidence against the standard hedonistic interpretation. Naturally, a great deal of the paper will revolve around an analysis of Mill's Utilitarianism, but special attention will also be paid to On Liberty, reading it as a development of Mill's moral theory rather than a mere application of it.     

Nuclear Boundaries: Material and Discursive Containment at the Hanford Nuclear Reservation

Abstract

Current controversies in the field of genetics are provoking a reassessment of claims that race is socially constructed. Drawing upon Bruno Latour's model of how to analyse scientific controversy, this article argues that race is ‘gaining in reality’ in such a way that renders claims about its social construction tenuous and uncertain. Such claims can be seen as failing in two key regards. The first relates to changes in the way genetics is practised and promoted, which are undermining the stability of fundamental assertions that there is ‘no biological basis for race’ or that ‘race does not exist’. The second involves the confusion of analytical domains in making assertions about race. This problem stems from investing genetics research with hopes that it would reveal the ‘truth’ about race. This confidence has led to equating the ‘cultural’ with ‘bias’, while ignoring the cultural dynamics which shape race. Subsequently, I argue for making a domain claim for the primacy of cultural analysis that does not simply dismiss the possible relevance of biology or genetics to racial issues.     

Fiction as a Base of Interpretation Contexts

In this paper, I want to deal with the problem of how to find an adequate context of interpretation for indexical sentences that enables one to account for the intuitive truth-conditional content which some apparently puzzling indexical sentences like “I am not here now” as well as other such sentences contextually have. In this respect, I will pursue a fictionalist line. This line allows for shifts in interpretation contexts and urges that such shifts are governed by pretense, which has to be understood in terms of socially shared make-believe games. By appealing to pretense so conceived, I will show that the fictionalist perspective is halfway between an intentionalist perspective, according to which the above indexical sentences have to be interpreted in a shifted intended context, (this perspective is primarily defined by Predelli 1998, Analysis 58, 107; Mind and Language 13, 400) and a conventionalist perspective, according to which indexical reference shifts in accordance with a conventional setting. (For this perspective, cf. Corazza et al. 2002, Philosophical Studies 107, See also Corazza 2004, Reflecting the Mind: Indexicality and Quasi-Indexicality, Oxford University Press). Finally, I will claim that the fictionalist analysis of cases of non-ordinary uses of indexicals like “here” and “now” can be retained in face of a new alternative analysis of those cases in terms of an ‘unbound anaphora’ – theory (cf. Corazza 2004, Synthese 138, 145).     

Building bridges with words: an inferential account of ethical univocity

Abstract

Explaining genuine moral disagreement is a challenge for metaethical theories. For expressivists, this challenge comes from the plausibility of agents making seemingly univocal claims while expressing incongruent conative attitudes. I argue that metaethical inferentialism – a deflationary cousin to expressivism, which locates meaning in the inferential import of our moral assertions rather than the attitudes they express – offers a unique solution to this problem. Because inferentialism doesn’t locate the source of moral disagreements in a clash between attitudes, but instead in conflicts between the inferential import of ethical assertions, the traditional problem for expressivism can be avoided. After considering two forms of inferentialism that lead to revenge versions of the problem, I conclude by recommending that we understand the semantics of moral disagreements pragmatically: the source of univocity does not come from moral or semantic facts waiting to be described, but instead from the needs that ethical and semantic discourses answer – a solution to the problems of what we are to do and how we are to talk about it.     

Some Notes on Boolos’ Semantics: Genesis,Ontological Quests and Model-Theoretic Equivalence to Standard Semantics

The main aim of this work is to evaluate whether Boolos’ semantics for second-order languages is model-theoretically equivalent to standard model-theoretic semantics. Such an equivalence result is, actually, directly proved in the “Appendix”. I argue that Boolos’ intent in developing such a semantics is not to avoid set-theoretic notions in favor of pluralities. It is, rather, to prevent that predicates, in the sense of functions, refer to classes of classes. Boolos’ formal semantics differs from a semantics of pluralities for Boolos’ plural reading of second-order quantifiers, for the notion of plurality is much more general, not only of that set, but also of class. In fact, by showing that a plurality is equivalent to sub-sets of a power set, the notion of plurality comes to suffer a loss of generality. Despite of this equivalence result, I maintain that Boolos’ formal semantics does not committ (directly) second-order languages (theories) to second-order entities (and to set theory), contrary to standard semantics. Further, such an equivalence result provides a rationale for many criticisms to Boolos’ formal semantics, in particular those by Resnik and Parsons against its alleged ontological innocence and on its Platonistic presupposition. The key set-theoretic notion involved in the equivalence proof is that of many-valued function. But, first, I will provide a clarification of the philosophical context and theoretical grounds of the genesis of Boolos’ formal semantics.     

Cryonics: Science or Religion

Cryonics involves the low-temperature freezing of human corpses in the hope that they will one day be reanimated. Its advocates see it as a medical treatment but as in any medical procedure, this presupposes some scientific evidence. This paper examines the scientific basis of this technology and argues that cryonics is based upon assertions which have never been (and potentially can never be empirically demonstrated) scientifically. After providing a general overview of cryogenic preservation, I discuss how advocates of this technology have conceptualized death and more specifically their notion of information-theoretic death. I conclude that cryonics is based upon a naive faith rather than upon science. It does what David Chidester (2005) calls ‘religious work,’ even if it is not explicitly religious. It offers transcendence over death.

     

Between Causes and Reasons: Sellars,Hegel (and Lewis) on “Sensation”

ABSTRACT

This paper explores Sellars’ and Hegel’s treatment of ‘sensation’ – a notion that plays a central role in the reflections of both authors but which has garnered little scholarly attention. To disentangle the issues surrounding the notion and elaborate its role, function, and fate in their thought, I begin with a methodological question: what kind of philosophical argument leads Sellars and Hegel to introduce the concept of ‘sensation’ into their systems? Distinguishing between their two argumentative approaches, I maintain that Hegel offers what I broadly label a ‘transcendental’ argument for ‘sensation,’ which he presents in the Philosophy of Subjective Spirit and in the corresponding Lectures, whereas Sellars introduces the notion of sensation for what I term empirically ‘explanatory’ reasons. Next, I closely analyze Hegel’s and Sellars’ theories of sensation to produce a textually supported and conceptually coherent reading of their views on the notion. To clarify my methodological distinction and its stakes in Hegel’s and Sellars’ I will reference Lewis’ notion of the given.
