In various arguments, Descartes relies on the principles that conceivability implies possibility and that inconceivability implies impossibility. Those principles are in tension with another Cartesian view about the source of modality, i.e. the doctrine of the free creation of eternal truths. In this paper, I develop a ‘two-modality’ interpretation of the doctrine of eternal truths which resolves the tension and I discuss how the resulting modal epistemology can still be relevant for the contemporary discussion.

In this paper, I will make the case that an associative account of predication in Hume seems to allow for impossible predicative conceptions—that is, the conceiving of impossible states of affairs involving subjects instantiating properties or qualities—which violate his Conceivability Principle. The natural response is to argue that such conceptions are not clear and distinct, but substantive worries are raised about a number of attempted solutions along these lines. This poses a predicament for Hume scholars: either we must modify or (...) abandon the Conceivability Principle, or reject an associative account of predication, or concede that Hume faces a difficulty he cannot solve.

This paper proposes a theological grounding for the possibility of metaphysics. After a brief critique of the seeming contemporary revival of analytic philosophy as characterized by linguisticism, the two main sections give a Christological and ultimately Mariological foundation for the possibility of metaphysics. The Christological section starts with the role of the second person of the Trinity in creation, and subsequently points to the hypostatic union as ensuring that creation is therefore accessible to the human mind. It also implies that (...) reality is fundamentally of a personal nature, and that personal knowledge can be relatively unproblematically acquired by other persons. The Mariological section starts from Plato’s Diotima as a prefigurement of Mary, and subsequently portrays Mary as the perfect metaphysician, guaranteeing the possibility of metaphysics as an enterprise of natural reason. Doing justice to the critique of an at times overly naive pre-modern metaphysics can then be done by advocating a Christological and Mariological turn for the Copernican revolution, e.g. fully taking into account the historicity of being and thinking. In conclusion, Mary as the handmaid of the Lord is analogous to metaphysics as the handmaid of theology, in a relationship of a loving daughter, mother and bride. (shrink)

The term ‘realism’ and its contrasting terms have various related senses, although often they occlude as much as they illuminate, especially if ontological and epistemological issues and their tenable combinations are insufficiently clarified. For example, in 1807 the infamous ‘idealist’ Hegel argued cogently that any tenable philosophical theory of knowledge must take the natural and social sciences into very close consideration, which he himself did. Here I argue that Hegel ably and insightfully defends Newton’s causal realism about gravitational force, in (...) part by exposing a fatal equivocation in the traditional concept of substance, by criticizing some still-standard empiricist misconceptions of force, by emphasizing the role of explanatory integration in Newtonian mechanics, and by using his powerful semantics of singular, specifically cognitive reference to justify fallibilism regarding empirical justification, together with the semantic core of Newton’s Rule Four of (experimental) Philosophy—in a way that highlights a key fallacy in many arguments against realism, both in epistemology and within philosophy of science.
