What's metaphysical about metaphysical necessity?

I begin by contrasting three approaches one can take to the distinction between the essential and accidental properties: an ontological, a deflationary, and a mind-dependent approach. I then go on to apply that distinction to the necessary a posteriori, and defend the deflationist view. Finally I apply the distinction to modal truth in general and argue that the deflationist position lets us avoid an otherwise pressing problem for the actualist: the problem of accounting for the source of modal truth

Metaphysical Rationalism

Material from this paper appears in Chap. 7 of my book Reason and Being, but there is also stuff here that isn't in the book. In particular, it discusses the claims that, for Spinoza, conceiving implies explaining and that existence is identical to or reducible to conceivability. So, if you're interested in those issues, this paper might be worth a read

Metaphysical and absolute possibility

It is widely alleged that metaphysical possibility is “absolute” possibility Conceivability and possibility, Clarendon, Oxford, 2002, p 16; Stalnaker, in: Stalnaker Ways a world might be: metaphysical and anti-metaphysical essays, Oxford University Press, Oxford, 2003, pp 201–215; Williamson in Can J Philos 46:453–492, 2016). Kripke calls metaphysical necessity “necessity in the highest degree”. Van Inwagen claims that if P is metaphysically possible, then it is possible “tout court. Possible simpliciter. Possible period…. possib without qualification.” And Stalnaker writes, “we can agree with Frank Jackson, David Chalmers, Saul Kripke, David Lewis, and most others who allow themselves to talk about possible worlds at all, that metaphysical necessity is necessity in the widest sense.” What exactly does the thesis that metaphysical possibility is absolute amount to? Is it true? In this article, I argue that, assuming that the thesis is not merely terminological, and lacking in any metaphysical interest, it is an article of faith. I conclude with the suggestion that metaphysical possibility may lack the metaphysical significance that is widely attributed to it

Disentangling Causal Pluralism

Causal pluralism is increasingly gaining interest as a promising alternative for monistic approaches toward causation. However, although the debate is scarcely out of the egg, the term ‘causal pluralism’ already covers diverse meanings. This creates confusion, and to remedy that confusion, it is necessary to discern different kinds of pluralistic approaches to causation and different possible positions within them. In this paper, I argue for a general distinction between conceptual causal pluralism, metaphysical causal pluralism and epistemological-methodological causal pluralism. I mainly focus on metaphysical approaches to causation and discern herein four possible positions: metaphysical causal constructivism, metaphysical causal monism, weak metaphysical causal pluralism, and strong metaphysical causal pluralism. Each of these positions are further related to their most obvious conceptual counterpart, specifically conceptual causal monism or conceptual causal pluralism

Conceivability and Modal Knowledge

Christopher Hill contends that the metaphysical modalities can be reductively explained in terms of the subjunctive conditional and that this reductive explanation yields two tests for determining the metaphysical modality of a proposition. He goes on to argue that his reductive account of the metaphysical modalities in conjunction with his account of modal knowledge underwrites the further conclusion that conceivability does not provide a reliable test for metaphysical possibility. I argue (1) that Hill’s reductive explanation of the metaphysical modalities in terms of the subjunctive conditional does not yield a reductive explanation of knowledge of metaphysical modality in terms of knowledge of subjunctive conditionals, and (2) that his account of modal knowledge is at odds with his contention that conceivability does not provide epistemic access to metaphysical possibility

Reflections on Metaphysical Explanation

The nature of metaphysical explanation is a question that should be constantly on every metaphysician’s mind, and yet it is rare to see explicit statements about the methodological approach that writers take. We tend to just enter the flow of ideas and words in a particular ‘discourse’ and see where it leads us. It is easier that way but can lead us astray. I can’t claim to be a role-model in this respect. I have offered a comment here, a remark there, but plenty room for improvement. However, I have come across quite a few confusions that can be traced to failed understanding of method/approach, and one or two really interesting statements of method. Here I share one such confusion about method, and one interesting view about method

Defending Contingentism in Metaphysics

Metaphysics is supposed to tell us about the metaphysical nature of our world: under what conditions composition occurs; how objects persist through time; whether properties are universals or tropes. It is near orthodoxy that whichever of these sorts of metaphysical claims is true is necessarily true. This paper looks at the debate between that orthodox view and a recently emerging view that claims like these are contingent, by focusing on the metaphysical debate between monists and pluralists about concrete particulars. This paper argues that we should be contingentists about monism and pluralism, and it defends contingentism against some necessitarian objections by offering an epistemology of contingent metaphysical claims

Metaphysical and Conceptual Grounding

Recently, many philosophers have claimed that the world has an ordered, hierarchical structure, where entities at lower ontological levels are said to metaphysically ground entities at higher ontological levels. Other philosophers have recently claimed that our language has an ordered, hierarchical structure. Semantically primitive sentences are said to conceptually ground less primitive sentences. It’s often emphasized that metaphysical grounding is a relation between things out in the world, not a relation between our sentences. But conflating these relations is easy to do, given that both types of grounding are expressed by non-causal “in-virtue-of” claims. The purpose of this paper is to clarify the relation between metaphysical and conceptual grounding. I argue that conceptual and metaphysical grounding are exclusive: if a given in-virtue-of claim involves conceptual grounding, then it does not involve metaphysical grounding. I also develop some heuristics for deciding which type of grounding is relevant in a given case. These heuristics suggest that many proposed cases of metaphysical grounding do not actually involve metaphysical grounding at all

Reclaiming Rationality Experientially: The New Metaphysics of Human Spirit in Hegel’s Phenomenology

Hegel’s Phenomenology of Spirit is typically read as a work that either rehabilitates the metaphysical tradition or argues for a new form of idealism centred on social normativity. In the following, I show that neither approach suffices. Not only does the metaphysical reading ignore how the Phenomenology demonstrates that human rationality can never adequately capture ultimate reality because ultimate reality itself has a moment of brute facticity that resists explanation, which prevents us from taking it as a logically self-contained, self-justifying metaphysical zone traditionally known as ‘substance,’ but it also ignores how the Phenomenology equally demonstrates that human rationality creates a historically self-unfolding universe of meaning that is, because it displays a rational systematicity and consistency unlike anything else in the world, the closest thing we have to substance, but which, given its freedom, is more correctly called ‘subject.’ Consequently, while the non-metaphysical reading rightly recognizes that the Phenomenology develops a radically innovative account of intersubjectivity, it neglects how the social theory that it develops comes fully equipped with various metaphysical commitments concerning nature, spirit, and the relationship between them without which this theory would be unintelligible
