Grounding: De Re and De Dicto

Abstract

Abstract Is the macro grounded in the micro? That is, is every truth about a macroscopic object fully grounded in a truth wholly about its microscopic parts? In a recent interesting paper, Martin Glazier argued for a negative answer. Following him, call the position that the macro is grounded in the micro ‘priority micro pluralism’ (‘pluralism’ for short). In this discussion note, I propose a way out for the pluralist. In brief, it consists in the recognition that some metaphysical positions, including pluralism, are best expressed by fundamentally de dicto grounding claims. In that these claims have a distinctive modal force, this recognition has far-reaching consequences that go beyond a defence of pluralism.
