The dissertation is in the format of a collection of several academic texts, composed of a two-part presentation and three papers on the topic of conceivability and the epistemology of modality. The presentation is composed of, first, a general introduction to conceivability theses and objections and, second, a discussion of two cases. Following the presentation, Asger provides three papers. The first paper, Pretense and Conceivability: A reply to Roca-Royes, presents a problem and a dilemma for Roca-Royes’ Non-Standard Dilemma for conceivability-based (...) epistemologies of de re modality in which she concludes that conceivability cannot be the whole story of our de re modal knowledge. The second paper, Conceivability Externalized, proposes an externalist conceivability-based epistemology of possibility inspired by Stalnaker. The third paper, Inconceivability as a Guide to Impossibility, considers inconceivability as an epistemic guide to impossibility, aiming to explore and add support to the underexplored thesis that one can justify beliefs about the impossibility of P on the basis of the inconceivability of P.

-/- Human beings are conscious not only of the world around them but also of themselves: their activities, their bodies, and their mental lives. They are, that is, self-conscious (or, equivalently, self-aware). Self-consciousness can be understood as an awareness of oneself. But a self-conscious subject is not just aware of something that merely happens to be themselves, as one is if one sees an old photograph without realising that it is of oneself. Rather a self-conscious subject is aware of themselves (...) as themselves; it is manifest to them that they themselves are the object of awareness. Self-consciousness is a form of consciousness that is paradigmatically expressed in English by the words “I”, “me”, and “my”, terms that each of us uses to refer to ourselves as such. -/- A central topic throughout the history of philosophy—and increasingly so since the seventeenth century—the phenomena surrounding self-consciousness prompt a variety of fundamental philosophical and scientific questions, including its relation to consciousness; its semantic and epistemic features; its realisation in both conceptual and non-conceptual representation; and its connection to our conception of an objective world populated with others like ourselves.

Descartes has a Clarity First epistemology: (i) Clarity is a primitive (indefinable) phenomenal quality: the appearance of truth. (ii) Clarity is prior to other qualities: obscurity, confusion, distinctness – are defined in terms of clarity; epistemic goods – reason to assent, rational inclination to assent, reliability, and knowledge – are explained by clarity. (This is the first of two companion entries; the sequel is called, "Descartes's Method for Achieving Knowledge.").

The distinction between the mental operations of abstraction and exclusion is recognized as playing an important role in many of Descartes’ metaphysical arguments, at least after 1640. In this paper I first show that Descartes describes the distinction between abstraction and exclusion in the early Rules for the Direction of the Mind, in substantially the same way he does in the 1640s. Second, I show that Descartes makes the test for exclusion a major component of the method proposed in the (...) Rules. Third, I argue that in Rule 14 the exclusion-abstraction distinction is connected to a theory of distinctions, which includes a notion of real distinction as essentially tied to the imagination. This sheds light on Descartes’ development in and after the Rules. (shrink)

In this work I argue that Descartes was not a trialist by showing that the main tenets of trialist interpretations of Descartes's theory of substance are either not supported by the text or are not sufficient for establishing the trialist interpretation.

Leibniz’s claim that it is possible for us to gain metaphysical knowledge through reflection on the self has intrigued many commentators, but it has also often been criticized as flawed or unintelligible. A similar fate has beset Leibniz’s arguments against materialism. In this paper, I explore one of Leibniz’s lesser-known arguments against materialism from his reply to Bayle’s new note L, and argue that it provides us with an instance of a Leibnizian “argument from reflection”. This argument, I further show, (...) does not constitute a flawed appeal to mere introspection, but is in fact securely grounded in an important corollary of the Principle of Sufficient Reason: Leibniz’s Principle of Intelligibility.

That there is an epistemological difference between the mental and the physical is well- known. Introspection readily generates knowledge of one’s own conscious experience, but fails to yield evidence for the existence of anything physical. Conversely, empirical investigation delivers knowledge of physical properties, but neither finds nor requires us to posit conscious experience. In recent decades, a series of neo-Cartesian arguments have emerged that rest on this epistemological difference and purport to demonstrate that mind-brain identity is false and that consciousness (...) is not even realized by or supervenient on physical properties. Where Descartes argued he could clearly and distinctly conceive mind and body as existing separately, contemporary anti-physicalists hold that the conceivability of worlds in which actual world correlations between physical and phenomenological properties fail shows that these correlations are contingent rather than logically or metaphysically necessary. Together with Descartes, they conclude from conceivability that identity, as well as strong supervenience, is false. 1 If the argument of this paper is correct, however, then there is an argument for dualism that arises from the epistemological distinction, is grounded in the Meditations, and is yet distinct from the " 1 " conceivability arguments pursued both by Descartes and contemporary anti-physicalists. Furthermore, the argument is immune to the standard objections to conceivability arguments: its conclusion follows even if there are a posteriori identities between physical and phenomenal properties.

Osobliwość takich doznań, jak ból, głód i pragnienie. Reliabilizm w drugiej części szóstej Medytacji Kartezjusza Artykuł omawia epistemiczny status cielesnych doznań takich, jak ból, głód i pragnienia, o których mowa w drugiej części szóstej Medytacji Kartezjusza. Argumentuję, że ów fragment stanowi integralny komponent epistemologicznego programu, który można znaleźć w Medytacjach. Na ogół widzi się Kartezjusza jako zwolennika infallibilizmu, internalizmu oraz fundacjonalizmu. Tymczasem w odniesieniu do wiedzy i przekonań opartych na doznaniach cielesnych przyjmuje on fallibilizm, eksternalizm i reliabilizm. Na rzecz tego (...) wniosku przemawia z jednej strony, analiza tego, czego naucza nas – według Kartezjusza – natura przez wrażenia bólu, głodu i pragnienia, z drugiej strony jego analiza błędów, którym podlega nasza natura, przeprowadzona przeze mnie z wykorzystaniem zaproponowanego przez Wilfrida Sellarsa podziału na logiczną przestrzeń rozumu oraz empiryczną przestrzeń przyczyn.
