Mark Schroeder has argued that all reasonable forms of inconsistency of attitude consist of having the same attitude type towards a pair of inconsistent contents (A-type inconsistency). We suggest that he is mistaken in this, offering a number of intuitive examples of pairs of distinct attitudes types with consistent contents which are intuitively inconsistent (B-type inconsistency). We further argue that, despite the virtues of Schroeder's elegant A-type expressivist semantics, B-type inconsistency is in many ways the more natural choice in developing (...) an expressivist account of moral discourse. We close by showing how to adapt ordinary formality-based accounts of logicality to define a B-type account of logical inconsistency and distinguish it from both semantic and pragmatic inconsistency. In sum, we provide a roadmap of how to develop a successful B-type expressivism. (shrink)

Tekst Naprawdę jaki jest Bernard Williams utwierdza mnie w przekonaniu, że moje odczytanie tezy internalizmu jest właściwe. Autorka polemiki opiera swą interpretację Williamsa na jednym jego tekście, nie uwzględnia też dyskusji, która toczy się od lat 80. na temat internalizmu, a jej zarzuty dotyczące poprawności mojej argumentacji wynikają z nietrafnego odczytania tego, co napisałem. Podtrzymuję tez tezę, wyrażoną wielokrotnie również przez Williamsa, że racje działania nie są zrelatywizowane względem wiedzy podmiotu. Zgadzam się natomiast z uwagą terminologiczną dotyczącą relatywizmu: wiele stanowisk, (...) które obecnie określane są przez filozofów jako relatywizm, należałoby określać innymi nazwami. (shrink)

This article gives an overview of some recent debates about the relationship between reasons and rational requirements of coherence - e.g. the requirements to be consistent in our beliefs and intentions, and to intend what we take to be the necessary means to our ends.

We believe we owe one another respect. We believe we ought to pay what we owe by treating one another ‘with respect.’ If we could understand these beliefs we would be well on the way to understanding morality itself. If we could justify these beliefs we could vindicate a central part of our moral experience.Respect comes in many varieties. We respect some people for their upright character, others for their exceptional achievements. There are people we respect as forces of nature: (...) we go to great lengths to accommodate their moods, wiles, and demands. Finally, most of us seem to respect people simply because they are people. This is the sort of respect of special interest to moral theory.In order to be worthy of this last sort of respect, it is not only sufficient but necessary that one be a person. We can, of course, take a similar attitude towardnonpersons. (shrink)

The authors investigated the ontological argument computationally. The premises and conclusion of the argument are represented in the syntax understood by the automated reasoning engine PROVER9. Using the logic of definite descriptions, the authors developed a valid representation of the argument that required three non-logical premises. PROVER9, however, discovered a simpler valid argument for God's existence from a single non-logical premise. Reducing the argument to one non-logical premise brings the investigation of the soundness of the argument into better focus. Also, (...) the simpler representation of the argument brings out clearly how the ontological argument constitutes an early example of a ?diagonal argument? and, moreover, one used to establish a positive conclusion rather than a paradox.

According to an influential view, asserting a proposition involves undertaking some “commitment” to the truth of that proposition. But accounts of what it is for someone to be committed to the truth of a proposition are often vague or imprecise, and are rarely put to work to define assertion. This article aims to fill this gap. It offers a precise characterisation of assertoric commitment, and applies it to define assertion. On the proposed view, acquiring commitment is not sufficient for asserting: (...) To assert, commitment must be acquired by explicitly presenting a proposition as true. (shrink)

Decision theorists widely accept a stochastic dominance principle: roughly, if a risky prospect A is at least as probable as another prospect B to result in something at least as good, then A is at least as good as B. Recently, philosophers have applied this principle even in contexts where the values of possible outcomes do not have the structure of the real numbers: this includes cases of incommensurable values and cases of infinite values. But in these contexts the usual (...) formulation of stochastic dominance is wrong. We show this with several counterexamples. Still, the motivating idea behind stochastic dominance is a good one: it is supposed to provide a way of applying dominance reasoning in the stochastic context of probability distributions. We give two new formulations of stochastic dominance that are more faithful to this guiding idea, and prove that they are equivalent. (shrink)

In _Consciousness and persons_, Michael Tye. Consciousness and persons. Cambridge, MA: MIT Press.) develops and defends a novel approach to the unity of consciousness. Rather than thinking of the unity of consciousness as involving phenomenal relations between distinct experiences, as standard accounts do, Tye argues that we should regard the unity of consciousness as involving relations between the contents of consciousness. Having developed an account of what it is for consciousness to be unified, Tye goes on to apply his account (...) of the unity of consciousness to the split-brain syndrome. I provide a critical evaluation of Tye's account of the unity of consciousness and the split-brain syndrome. (shrink)

In A Metaphysics for Freedom, Helen Steward proposes and defends a novel version of the libertarian account of free action. Amongst several objections that she considers to her view, one that looms particularly large is the Challenge from Chance: ‘the most powerful, widely-promulgated and important line of anti-libertarian reasoning’. This paper begins by arguing that Steward’s response to the Challenge is not fully convincing. It then goes on to explore a further possible libertarian line of defence against the Challenge, arguing (...) that it, too, ultimately fails. The conclusion is that the Challenge remains an important source of dialectical advantage for the compatibilist. (shrink)

Frege argued for the force-content distinction not only by appealing to the logical and fictional contexts which are most closely associated with the “Frege point", but also based on the fact that an affirmative answer to a yes-no question constitutes an assertion. Supposedly this is only intelligible if the question contains a forceless thought or proposition which an affirmative answer then asserts. Against this I argue that this fact more readily supports the view that questions operate on assertions and other (...) forceful acts themselves. Force is neither added to propositions as on the traditional view, nor is it cancelled as has recently been proposed. Rather higher-level acts such as questioning, but also e.g. conditionalizing, embed and present assertoric or directive acts that are forceful and committal, while suspending commitment to them. The Frege point confounds different varieties of force and the question whether something is merely presented for consideration with the question what is so presented. Force is representational: through assertoric and directive force indicators subjects non-conceptually present positions of theoretical or practical knowledge, while interrogative acts indicate positions of wondering which strive for such knowledge.

Il platonista sostiene che le verità della matematica e della logica siano letteralmente vere, ossia che descrivano (in qualche modo: non voglio legare la definizione a una particolare teoria semantica) realtà che non sono create o decise da noi. Il convenzionalista sostiene invece che le proposizioni che chiamiamo verità della matematica siano in qualche misura convenzionali: esse esprimerebbero convenzioni che abbiamo adottato noi, o certe loro conseguenze. Le due posizioni sono apparenteme...

Imagination is analysed by contemporary philosophers of mind in order to discover its features and its place in our cognitive architecture. More precisely, the debate has given birth to two competing approaches: simulationism and single-code theory. However, a third, intermediary view, is possible, as Mulligan’s proposal suggests. In this paper I propose a certain type of simulationism, namely a conception of imagination based on a homomorphic functional simulation. Inspired by Mulligan’s position, I will argue that this type of simulationism is (...) in fact neutral with respect to the disagreement between classical simulationists and single-code theorists. It can even be regarded as the common ground of these approaches. (shrink)

A reply to two responses to an earlier paper, "A Liar Paradox".

Philosophical Perspectives, Volume 35, Issue 1, Page 23-49, December 2021.

This paper develops an account of the nature of imagination as a discrete mental process underpinned by a specialised neural and computational architecture. The account integrates evidence from cognitive neuroscience and developmental psychology with philosophical arguments about the nature of imagination. We situate the account against other philosophical accounts and apply it to the understanding of some puzzling phenomena: delusion, pretence and self-deception. We argue that many of the puzzling features of these phenomena arise because they are analysed with a (...) doxastic framework. When the role of imagination in these cases is properly understood these puzzles become more tractable. (shrink)

This paper distinguishes revolutionary fictionalism from other forms of fictionalism and also from other philosophical views. The paper takes fictionalism about mathematical objects and fictionalism about scientific unobservables as illustrations. The paper evaluates arguments that purport to show that this form of fictionalism is incoherent on the grounds that there is no tenable distinction between believing a sentence and taking the fictionalist's distinctive attitude to that sentence. The argument that fictionalism about mathematics is ‘comically immodest’ is also evaluated. In place (...) of those arguments, an argument against fictionalism about abstract objects of any kind is presented in the last section. This argument takes the form of a trilemma against the fictionalist. (shrink)

Stanford Encyclopedia article surveying the life and work of D.C. Williams, notably in defending realism in metaphysics in the mid-twentieth century and in justifying induction by the logic of statistical inference.

David Lewis (1941–2001) was one of the most important philosophers of the 20th Century. He made significant contributions to philosophy of language, philosophy of mathematics, philosophy of science, decision theory, epistemology, meta-ethics and aesthetics. In most of these fields he is essential reading; in many of them he is among the most important figures of recent decades. And this list leaves out his two most significant contributions. -/- In philosophy of mind, Lewis developed and defended at length a new version (...) of materialism (see the entry on physicalism). He started by showing how the motivations driving the identity theory of mind and functionalism could be reconciled in his theory of mind. He called this an identity theory, though his theory motivated the position now known as analytic functionalism. And he developed detailed accounts of mental content (building on Davidson’s interpretationism) and phenomenal knowledge (building on Nemirow’s ability hypothesis) that are consistent with his materialism. The synthesis Lewis ended up with is one of the central positions in contemporary debates in philosophy of mind. -/- But his largest contributions were in metaphysics. One branch of his metaphysics was his Hume-inspired reductionism about the nomological. He developed a position he called “Humean supervenience”, the theory that said that there was nothing to reality except the spatio-temporal distribution of local natural properties. And he did this by showing in detail how laws, chances, counterfactual dependence, causation, dispositions and colours could be located within this Humean mosaic. The other branch of his metaphysics was his modal realism. Lewis held that the best theory of modality posited concrete possible worlds. A proposition is possible if and only if it is true at one of these worlds. Lewis defended this view in his most significant book, On the Plurality of Worlds. Alongside this, Lewis developed a new account of how to think about modal properties of individuals, namely counterpart theory, and showed how this theory resolved several long-standing puzzles about modal properties.

Natural kind realists believe that the world is carved out into kinds of things. Critiques addressed towards natural kind realism aimed at showing the difficulties in discerning a universal spatial structure and behavior common to all the members of an alleged kind. Little or no attention, however, has been given to the temporal structure of a natural kind. After showing (in the first section) that some kinds are indeed temporally extended, the second section of the paper argues that there is (...) no non-arbitrary way of tracing the natural temporal structure of a kind. The accrued result poses a novel problem for natural kind theorists, as it clashes with the basic expectancy that if a kind is indeed natural, both its spatial and temporal boundaries should be (at least in principle) discernible.
