A minimal truthmaker for a given proposition is the smallest portion of reality which makes this proposition true. Minimal truthmakers are frequently mentioned in the literature, but there has been no systematic account of what they are or of their importance. In this article we shall clarify the notion of a minimal truthmaker and argue that there is reason to think that at least some propositions have minimal truthmakers. We shall then argue that the notion can play a useful role (...) in truthmaker theory, by helping to explain the truth of certain propositions as precisely as possible. (shrink)

Recent work on metaphysical grounding has suggested that physicalism can be characterised in terms of the mental facts being grounded in physical facts. It is often assumed that the full grounds of a fact metaphysically necessitate that fact. Therefore, it seems that if the physical grounds the mental, then the physical facts metaphysically necessitate the mental facts. Stefan Leuenberger argues that such a version of physicalism would be vulnerable to counterexamples. I shall outline a characterisation of grounding which appeals to (...) a relation between grounding and the essences of properties instantiated in the grounded facts or in their grounds. If a grounded fact is such that its constituent property is essentially related to the properties instantiated in its grounds, or vice versa, then the grounded fact will be metaphysically necessitated by its full grounds. This characterisation of grounding not only avoids Leuenberger’s counterexamples, but has broader implications for characterising physicalism in terms of grounding. (shrink)

Substance has long been one of the key categories in metaphysics. This Element focuses on contemporary work on substance, and in particular on contemporary substance ontologies, metaphysical systems in which substance is one of the fundamental categories and individual substances are among the basic building blocks of reality. The topics discussed include the different metaphysical roles which substances have been tasked with playing; different critieria of substancehood (accounts of what is it to be a substance); arguments for and against the (...) existence of substances; and different accounts of which entities, if any, count as substances1.

The priority monist holds that the cosmos is the only fundamental object, of which every other concrete object is a dependent part. One major argument against monism goes back to Russell, who claimed that pluralism is favoured by common sense. However, Jonathan Schaffer turns this argument on its head and uses it to defend priority monism. He suggests that common sense holds that the cosmos is a whole, of which ordinary physical objects are arbitrary portions, and that arbitrary portions depend (...) for their existence on the existence of the whole. In this paper, we challenge Schaffer’s claim that the parts of the cosmos are all arbitrary portions. We suggest that there is a way of carving up the universe such that at least some of its parts are not arbitrary. We offer two arguments in support of this claim. First, we shall outline semantic reasons in its favour: in order to accept that empirical judgements are made true or false by the way the world is, one must accept that the cosmos includes parts whose existence is not arbitrary. Second, we offer an ontological argument: in order for macro-physical phenomena to exist, there must be some micro-physical order which they depend upon, and this order must itself be non-arbitrary. We conclude that Schaffer’s common sense argument for monism cannot be made to work. (shrink)

A common conception of facts is as worldly entities, complexes made upof non-factual constituents such as properties, relations andproperty-bearers. Understood in this way facts face the unityproblem, the problem of explaining why various constituents arecombined to form a fact. In many cases the constituents could haveexisted without being unified in the fact---so in virtue of what arethey so unified? I shall present a new approach to the unity problem.First, facts which are grounded are unified by the obtaining of theirgrounds. Second, (...) many ungrounded facts are such that they must obtainif their non-factual constituents exist (e.g. if the property $F$nessis essential to a particular, $a$, then if $a$ exists the fact that$a$ is $F$ must obtain). In this way the obtaining of these facts isexplained by the essence of some of their constituents. I alsoaddress the possibility of facts which are brutely unified(i.e. neither grounded nor essentially unified), and compare theaccount I offer with some of the main alternatives. (shrink)

Abstract John McDowell has claimed that the rational link between perceptions and empirical judgements allows us to perceive objects as belonging to a wider reality, one which extends beyond the objects perceived. In this way, we can be said to have a perceptual awareness of the world. I argue that McDowell's account of this perceptual awareness does not succeed. His account as it stands does not have the resources to explain how our perceptions can present objects as belonging to a (...) wider reality, regardless of the judgements we make about that reality. I suggest that we can give a better account of this perceptual awareness of the world by appealing to transcendental phenomenology. A phenomenological study of perceptual experiences describes how they are structured by a sense of the perceived objects as belonging to a world containing other objects of possible perception. I shall outline this sense we have of the world, and argue that it allows us to perceive objects as belonging to a wider reality. Transcendental phenomenology can thus help to explain our perceptual awareness of the world. (shrink)
