AN OPEN ACCESS Ergo JOURNAL OF PHILOSOPHY Essential Truths and Their Truth-Grounds ROBERT MICHELS eidos – the centre for metaphysics & University of Neuchâtel This paper motivates and defends a principle which captures a systematic connection between essence, truth, and grounding. It says that if a proposition expresses an essential truth, i.e., if it is true in virtue of the nature of some objects, then there are grounds for its truth which involve these objects. Together with the assumption that a fact can only be grounded in facts which are relevant to it, this principle is then applied in an argument against the monotonicity of the Essentialist notion ‘true in virtue of the nature of’. 1. Essential Truth and Ground There is a current trend in analytic philosophy of abandoning the austere view of metaphysics set out in Quine (1948) and of theorizing not only about which enti- ties exist, but also about their essences and about structural relations of grounding which hold between facts containing them. A broadly Neo-Aristotelian approach to the notions of essence and ground has recently enjoyed much attention both in metaphysics, meta-metaphysics, and other philosophical sub-disciplines.1 An important open question about this approach, which has recently attracted con- siderable interest, is how these two notions relate.2 Inquiries into the relation between essence and ground are not only of intrinsic interest, but also promise new insights about each of the two notions, or so I will argue in this paper. The focus in this paper is on a particular principle, the Linking Principle, which Contact: Robert Michels <
