In this paper, I consider the question of whether calibration is required for modalizing mechanisms to be reliable, that is, whether it is necessary for modalizing mechanisms to be adjusted to prevent overgeneration and undergeneration of modal beliefs. I first argue that the calibration requirement affects differently what I call bootstrapping and ordinary cases. Identifying different ways in which a modalizing mechanism could be calibrated, I argue that not all of them are effective or even viable in bootstrapping cases. Then, (...) by taking a diachronic perspective, I offer a simplified account of how different calibration mechanisms can be bootstrapped, with an emphasis on the social dimension of modal judgment.

Vaidya and Wallner [2021] claim that most relevant theories in recent epistemology of modality, that is, Conceivability-Theory, Counterfactual-Theory, and Deduction-Theory, face what they name “the problem of modal epistemic friction”, in a nutshell, the need to add some relevant information about the nature of the world that is not provided by the theories as such. Their proposal is that essences supply the needed information. In this paper I will agree with Vaidya and Waller’s detection of the problem of modal epistemic (...) friction, but I will importantly disagree with their solution in terms of a metaphysics and epistemology of essences. I will argue that knowledge of essence is neither necessary nor sufficient for metaphysical modal knowledge and claim instead that modal knowledge is firstly grounded in the categories that conform the facts of reality. Categorial knowledge does the job of creating the friction needed in all cases of modal metaphysical knowledge.Moreover, given the structural character of metaphysical categories, intuition is the basic proper form of modal knowledge. In fact, I will contend that intuition is the source of a priori knowledge invoked in Kripkean schemas for a posteriori modal truths. (shrink)

Can experience justify modal beliefs? A long tradition dating back to Descartes, Hume, and Kant, which denies that experience plays a justificatory role in modal justification, says ‘no’. Here, I answer ‘yes’. Specifically, I argue that perception justifies some of our modal beliefs, namely the perceptual ones. Using a naturalized reliabilist framework for perceptual justification, I argue that one of the assumptions perception makes about the world, which enables it to organize itself, is modal—namely, ‘objects presented within peripersonal space are (...) reachable and graspable’—such that relying on this modal assumption, perception outputs modal beliefs reliably, and so we can render perceptual modal justification as a function of the reliability of perception as a modal-belief-forming process.

This paper scrutinises the limits of a posteriori induction in acquiring modal knowledge. I focus on my similarity-based account (Roca-Royes [2017]); an inductive, non-rationalist epistemology of modality about concrete entities. Despite the explanatory merits of the account in relation to a vast range of modal claims, this inductive epistemology has been found incapable of yielding knowledge of a certain, other range of modal claims. Here, two notions of knowability are distinguished which reveal some of these limitations to be not only (...) accidental to the method but also virtuous. Additionally, the scrutiny suggests a recipe for increasingly pushing back, as modal enquirers, some of these limits. Limits will irremediably remain. But, as modal epistemologists, it is to explain what lies beyond these irremediable limits (not within) that we should look somewhere else. (shrink)

We describe the main issue debated at the IV Blasco Disputatio: whether our knowledge of metaphysical possibility and necessity rests on knowledge of essence. But before getting to this specific issue, we offer a broader introduction to the more general problems in the epistemology of modality. In this way, we establish a background against which the contributions to this SI can be better appreciated.

Vaidya & Wallner [2021] have recently formulated the Problem of Modal Epistemic Friction (PMEF) for three of the most discussed accounts in the epistemology of modality: conceivability-based, counterfactual-based and deduction-based accounts. They propose essentialist solutions in all three cases, arguing that all three discussed accounts should be supplemented by a suitable epistemology of essence. In this paper I argue that the PMEF also applies to Roca-Royes’ similarity-based account in the epistemology of modality. I also discuss if or to what extent (...) the version of the PMEF that applies to Roca-Royes can be given an essentialist solution. With regard to this question, I argue that besides the inductivist variant of the similarity-based account that Roca-Royes favors, there might also be an essentialist variant that would be successful in at least some cases. As for Roca-Royes’ inductivist variant I argue that the PMEF ultimately boils down to the notorious Problem of Induction. I shall discuss a popular solution to the Problem of Induction and the role essences might play in it. (shrink)

In this paper, I examine Brandom’s notion of a de re reading of a tradition and question its legitimacy under certain circumstances. Specifically, I argue that within the language game of giving and asking for reasons, commitments should be ascribed to the utterer within reasonable limits, with the utterer only responsible for intentional or negligent breaches of duty. Even if we were to include an ideal speaker who knows all facts available at the time of her utterance, she cannot be (...) held accountable for ignorance of things that do not yet exist. Therefore, I further argue that the time of the utterance must be taken into consideration when ascribing commitments and keeping score in the game of giving and asking for reasons. This temporal aspect is suppressed by Brandom’s notion of de re reading for pragmatic reasons, as he seeks to tell an inferentialist story of the philosophical tradition. Nevertheless, I argue that legitimacy poses a problem even for this approach because Brandom formulates his account in terms of rules, responsibility and sanctions. I offer a critical perspective on Brandom’s de re reading and the broader implications of his inferentialist framework. (shrink)

This paper argues for the claim that the mental ontology required for what has been called the “Phenomenal Intentionality Theory” (PIT) should be understood in terms of mental events or episodes, not mental states that instantiate phenomenal properties because the former but not the latter has a kind of temporal shape. I begin by laying out the basic commitments of PIT. I then introduce the notion of “temporal shape” and defend the following simple but powerful argument: (1) If conscious experiences (...) are phenomenal mental states that instantiate phenomenal properties, then the phenomenal character of these experiences will lack a temporal shape. (2) The phenomenal character of conscious experience typically has a temporal shape. (3) Therefore, conscious experiences are not mental states that instantiate phenomenal properties. (shrink)

Aristotle’s notion of deduction (syllogism) differs from the conception of logical consequence in classical logic in two essential features, which are required by Aristotle’s definition of syllogism and are incorporated into his formalisation of deduction: in addition to the standard necessary truth-preservation, Aristotle requires relevance of premises for the conclusion and non-repetition of premises in the conclusion. These requirements, together with Aristotle’s conception of simple propositions, lead to the result that valid deductive steps (syllogisms) must have very specific forms, namely (...) the well-known syllogistic shape. All other kinds of deduction lacking this shape, such as “syllogisms based on a hypothesis”, can be considered “syllogisms” only in a relative sense: they are based on an assumption of the existence of genuine syllogistic deductions in the syllogistic shape. Aristotle’s demands should cover all kinds of deduction: all valid deduction must be relevant and non-repetitive. This brings Aristotle’s definition much closer to the intuition associated with the notion of logical consequence. (shrink)

Following Kant, Frege took the idea that there is such a thing as bona fide a priori knowledge of a large range of necessary propositions for granted. In particular he assumed that such is the character of our knowledge of basic logic and arithmetic. This view is no longer orthodoxy. The idea that pure (for Frege, logical) intellection can provide for substantial knowledge of necessary features of the world is widely regarded with suspicion. However it is fair to say that (...) most recent scepticism about it has been driven either by abstract background theoretical commitments—for instance, by a thoroughgoing empiricism, as in Mill and Quine, or by epistemological externalism1—or by the conviction that the concept of a priori justification allows of no stable, theoretically interesting characterisation.2 The present discussion focuses on the example of elementary arithmetic to develop and explore a different, relatively neglected and, it may be suggested, more fundamental kind of sceptical challenge, one prefigured in the writings on mathematics of the later Wittgenstein but independent of the discussion of following a rule to which his generally deflationary or conventionalist cast of thinking about mathematical knowledge is, after Kripkenstein,3 nowadays usually attributed. Elementary arithmetical truths are normally taken to be justifiable a priori if any truths are. They are also normally taken to be both necessary and substantial—essentially applicable to our dealings with the world and empirically predictive, yet good for counterfactual reasoning about however far-fetched and exotic scenarios. Yet, I will argue, scrutiny of the kind of methods—simple informal cognitive routines involving counting and pictures—whereby such judgements are initially apt to win our confidence serves to make it puzzling how they can justify what they are supposed to at all: how such procedures can merit either the very high levels of confidence we standardly place in the judgements they lead to, or the modal (counterfactual) significance we standardly attach to those judgements. The present discussion elaborates these apparent shortfalls (§§2–4) and reviews four proposals (§§5–8) for redressing them, arguing that each is ineffective. The sceptical challenge accordingly stands unanswered. §9 elaborates its relation to one strand in the Remarks on the Foundations of Mathematics. §10 summarises the resulting dialectical position. The upshot, I believe, is a deepened understanding of an important aspect of Wittgenstein’s later philosophy and a major intellectual challenge to those—possibly still a majority—who incline to side with Frege’s view of the epistemological status of arithmetic.

One argument against epiphenomenalism arises from the theory of evolution. A particularly powerful form of this argument was developed by William James. James argued against epiphenomenalism on the grounds that, if it were correct, it would be inexplicable why the things that we find pleasurable are mostly beneficial to us while the things we find painful are mostly harmful. The aim of the present paper is to defend and extend James’s argument. James’s argument is here defended against criticisms due to (...) Karl Popper, John Eccles and William Robinson. Recently, an argument similar to James’s has been developed by Hedda Hassel Mørch. Mørch argues that the phenomena to which James drew our attention can be explained if we say pleasure and pain have phenomenal powers. In the present paper it is argued that, as it stands, the argument developed by Mørch is not satisfactory. It is argued that Mørch’s account needs to be supplemented with the thesis that the self has certain causal powers. A similar addition, it is argued, needs to be made to a position defended by Bradford Saad. The paper argues that, supplemented with the appropriate attributions of causal powers to the self, James’s argument against epiphenomenalism is effective. (shrink)
