Logical Essence [Special Issue]
Issue: Issue 14 • Author/s: Jessica Leech
Topics: Epistemology, Metaphysics, Modal Logic, Ontology, Philosophical logic
An increasingly popular view at the intersection of logic and metaphysics is that logical necessities have their source in the essences of logical entities: metaphysical necessity has its source in the essences or natures of things, and logical necessity is a restriction of metaphysical necessity. But logical and metaphysical necessity are, nevertheless, importantly distinct: there are metaphysical necessities that are not logical necessities. I raise a serious problem for this essentialist view. It seems as though they must misclassify some merely metaphysical necessities as logical necessities. I argue that the…
Laws of Metaphysics for Essentialists [Special Issue]
Issue: Issue 19 • Author/s: Tuomas Tahko
Topics: Epistemology, Metaphysics, Ontology, Philosophy of science, Theoretical philosophy
A recent methodological approach at the interface of metaphysics and philosophy of science suggests that just like causal laws govern causation, there needs to be something in metaphysics that governs metaphysical relations. Such laws of metaphysics would be counterfactual-supporting general principles that account for the explanatory force of metaphysical explanations. There are various suggestions about how such principles could be understood. They could be based on what Kelly Trogdon calls grounding-mechanical explanations, where the role that grounding mechanisms play in certain metaphysical explanations mirrors the role that causal mechanisms play…
The Pragmatics of Metaphysics Explanation: An Epistemology of Grounding [Special Issue]
Issue: Issue 19 • Author/s: James Lee
Topics: Epistemology, Metaphysics, Ontology, Theoretical philosophy
Explanation can be distinguished between linguistic practices and metaphysical relations. At least with respect to metaphysical explanation, some are skeptical that any knowledge gained via explanation qua linguistic practices confers knowledge of explanation qua metaphysical relation. I argue that this skepticism is unfounded. Engaging in the linguistic practice of explanation gives us no reason to skeptical in beliefs about corresponding metaphysical relations like causation or grounding. Moreover, those very linguistic practices can provide resources to justify beliefs in those relations. So, exploring those practices can move us forward in developing…
Essence, Necessity, and Non-Generative Metaphysical Explanation [Special Issue]
Issue: Issue 14 • Author/s: Michael Wallner
Topics: Epistemology, Metaphysics, Modal Logic, Ontology, Philosophical logic
Finean essentialists take metaphysical necessity to be metaphysically explained by essence. But whence the explanatory power of essence? A recent wave of criticism against the Finean account has put pressure on essentialists to answer this question. Wallner and Vaidya (2020) have responded by offering an axiomatic account of the explanatory power of essence. This paper discusses their account in light of some recent criticism by Bovey (2022). Building on work by Glazier (2017), Bovey succeeds in showing that Wallner and Vaidya’s account is in need of modification and clarification. In…
Relativized Essentialism about Modalities [Special Issue]
Issue: Issue 14 • Author/s: Salim Hirèche
Topics: Epistemology, Metaphysics, Modal Logic, Ontology, Philosophical logic
On what I call absolutist essentialism about modality (AE), the metaphysical necessities are the propositions that are true in virtue of the essence (i.e. Aristotelian, absolute essence) of some entities. Other kinds of necessity can then be defined by restriction—e.g. the conceptual necessities are the propositions that are true in virtue of the essence of conceptual entities specifically. As an account of metaphysical modality and some other kinds (e.g. logical, conceptual), AE may have important virtues. However, when it comes to accounting for further important kinds, like natural or normative…
Essence and Knowledge [Special Issue]
Issue: Issue 19 • Author/s: Daniele Sgaravatti
Topics: Epistemology, Metaphysics, Modal Logic, Ontology, Theoretical philosophy
In this paper I will attempt to show that there are some essential connections between essence and knowledge, and to clarify their nature. I start by showing how the standard Finean counterexamples to a purely modal conception of essence suggest that, among necessary properties, those that are counted as essential have a strong epistemic value. I will then propose a “modal-epistemic” account of essence that takes the essential properties of an object to be precisely the sub-set of its necessary properties that constitute a significant source of knowledge about it.…
