My goal in this paper is to provide characterizations of matter, form and constituency in a way that avoids what I take to be the three main drawbacks of other hylomorphic theories: (i) commitment to the universal-particular distinction; (ii) commitment to a primitive or problematic notion of inherence or constituency; (iii) inability to identify viable candidates for matter and form in nature, or to characterize them in terms of primitives widely regarded to be intelligible.

Many contemporary proponents of hylomorphism, the view that at least some material objects are comprised of both matter and form, endorse a version of hylomorphism according to which the form of a material object is a certain complex relation or structure. In this paper, I introduce three sorts of concerns for this “structural” approach. First, I argue that, in countenancing an abundance of overlapping yet numerically distinct material objects, “structural hylomorphists” are committed to a certain sort of systematic causal overdetermination. (...) Second, I argue that, because of its relatively thin conception of form, the view risks collapsing into some already well-entrenched metaphysical account of material objects. Finally, I argue that because the view emphasizes the more static structural features of composite material objects, structural hylomorphists seem unable to explain how it is that those objects might be said to persist over time through changes in such features.

Many contemporary proponents of hylomorphism endorse a version of hylomorphism according to which the form of a material object is a certain kind of complex relation or structure. Structural approaches to form, however, seem not to capture form’s traditional role as the guarantor of diachronic identity, since more “dynamically complex” material objects, such as living organisms, seem to undergo, and survive, various structural changes over the course of their existence. As a result, some contemporary hylomorphists have looked to alternative, non-structural (...) approaches to form. One of the leading non-structural approaches is the powers approach, according to which the form of a material object is a certain kind of power continuously activated in the object or in its material parts. In this paper, I begin by offering an overview and assessment of this powers approach to form. I argue that while the powers approach captures some crucial elements for understanding the nature of more dynamically complex material objects, when we press on the details of the view we find that it actually points to a related, but importantly distinct, third approach to understanding form, according to which the form of a material object is a certain kind of activity or process in which the material object or its parts are continuously engaged. I call this third approach “Hyloenergeism”. In the second half of the paper, I consider what such a view of material objects might look like and what its principal virtues might be. (shrink)

The Aristotelian doctrine of hylomorphism has seen a recent resurgence of popularity, due to the work of a number of well-known and impressive philosophers. One of the recently motivating virtues claimed for the doctrine is its ability to solve the grounding problem for philosophers who believe in coinciding entities. In this brief article, I will argue that when fully spelled out, hylomorphism does not, in fact, contribute a distinctive solution to this problem. It is not that it offers no solution (...) at all, but that it is not really a different solution from other familiar, seemingly non-hylomorphic, solutions on offer. (shrink)

Neo-Aristotelian hylomorphism has struggled to arrive at anything approaching a consensus regarding the notion of form. Contending that no ‘right-minded modern’ could embrace anything akin to Arist...

In this paper we present the standard Thomistic view concerning substances and their parts. We then note some objections to that view. Afterwards, we present Aquinas’s Christology, then draw an analogy between the relation that holds between the Second Person and the assumed human nature, on the one hand, and the relation that holds between a substance whole and its substance parts, on the other. We then show how the analogy, which St. Thomas himself drew at points, is useful for (...) providing a theory that answers the objections that the standard Thomistic view faces. Finally we answer objections to our approach. We conclude that there is a hylomorphic theory, founded on an analogy from Aquinas’s Christology, that fits well with the empirical data concerning substance parts, on which some complete created material substances have other complete created material substances as parts.

I address two related questions. First: what value is there in visiting a museum and becoming acquainted with the objects on display? For art museums the answer seems obvious: we go to experience valuable works of art, and experiencing valuable works of art is itself valuable. In this paper I focus on non-art museums, and while these may house aesthetically valuable objects, that is not their primary purpose, and at least some of the objects they house might not be particularly (...) aesthetically valuable at all. Second: to what ontologicaltypeorcategorydo museum objects belong? Whattypeof item should be featured on an inventory of a museum collection? I distinguish betweentypicalobjects andspecialobjects. While these are different types of object, both, I argue, areabstracta, notconcreta. The answer to the second question, concerning the ontological category of special objects, throws new light on various philosophical questions about museums and their collections, including the question about the value of museum experiences. But it also throws light on important questions concerning the preservation and restoration of museum objects. (shrink)

In a difficult but fascinating passage in Metaphysics Z.17, Aristotle puts forward a proposal, by means of a regress argument, according to which a whole or matter/form-compound is one or unified, in contrast to a heap, due to the presence of form or essence. This proposal gives rise to two central questions: (i) the question of whether form itself is to be viewed, literally and strictly speaking, as part of the matter/form-compound; and (ii) the question of whether form is to (...) be regarded as itself having parts. It is argued that both questions may be answered affirmatively, without giving rise to a regress worry. (shrink)

A staunch hylomorphism involves a commitment to a sparse theory of universals and a sparse theory of composite material objects, as well as to an ontology of fundamental causal powers. Faint-hearted hylomorphism, in contrast, lacks one or more of these elements. On the staunch version of HM, a substantial form is not merely some structural property of a set of elements—it is rather a power conferred on those elements by that structure, a power that is the cause of the generation (...) (by fusion) and persistence of a composite whole through time. Bernard Williams discussed (and rejected) a faint-hearted version of HM in 1986, and faint-hearted HM has been defended more recently by Mark Johnston (2006) and Kathrin Koslicki (2008). I defend the superiority of the staunch version, in spite of its heavier ontological commitments, as a way of accounting for a real distinction between living organisms and heaps of matter, without recourse to dualism or vitalism, and as a way of combining a powers ontology with the possibility of gunk.

“Hylomorphism” has recently become a buzzword in metaphysics. Kit Fine, Kathryn Koslicki, and Mark Johnston, among others, have argued that hylomorphism provides an account of parthood and material constitution that has certain advantages over its competitors. But what exactly is it, and what are its implications for an account of what we are? Hylomorphism, I argue, is fundamentally a claim about structure. It says that structure is a basic ontological and explanatory principle. I argue that hylomorphism is compatible with physicalism, (...) and also with substance dualism, and epiphenomenalism. The most interesting kinds of hylomorphism nevertheless reject these views. I describe one such hylomorphic theory. It is an empirically well-warranted theory, I argue, one based on work in biology and biological subdisciplines such as neuroscience. (shrink)

Hylomorphism claims that structure is a basic ontological and explanatory principle; it accounts for what things are and what they can do. My goal is to articulate a metaphysic of hylomorphic structure different from those currently on offer. It is based on a substance-attribute ontology that takes properties to be powers and tropes. Hylomorphic structures emerge, on this account, as powers to configure the materials that compose individuals.

We defend hylomorphism against Maegan Fairchild’s purported proof of its inconsistency. We provide a deduction of a contradiction from SH+, which is the combination of “simple hylomorphism” and an innocuous premise. We show that the deduction, reminiscent of Russell’s Paradox, is proof-theoretically valid in classical higher-order logic and invokes an impredicatively defined property. We provide a proof that SH+ is nevertheless consistent in a free higher-order logic. It is shown that the unrestricted comprehension principle of property abstraction on which the (...) purported proof of inconsistency relies is analogous to naïve unrestricted set-theoretic comprehension. We conclude that logic imposes a restriction on property comprehension, a restriction that is satisfied by the ramified theory of types. By extension, our observations constitute defenses of theories that are structurally similar to SH+, such as the theory of singular propositions, against similar purported disproofs. (shrink)

Hylomorphism offers a third way between animalist approaches to personal identity, which maintain that psychology is irrelevant to our persistence, andneo-Lockean accounts, which deny that humans are animals. This paper provides a Thomistic account that explains the intuitive responses to thought experiments involving brain transplants and the transformation of organic bodies into inorganic ones. This account does not have to follow the animalist in abandoning the claim that it is our identity which matters in survival, or countenance the puzzles of (...) spatially coincident entities that plague the neo-Lockean. The key is to understand the human being as only contingently an animal. This approach to our animality is one that Catholics have additional reason to hold given certain views about purgatory, our uniqueness as free and rational creatures, and our having once existed as zygotes.

The view that ordinary objects are composites of form and matter ("hylomorphism") can be contrasted with the more common view that ordinary objects are composed of only material parts ("matter only"). On a matter-only view the hard question is modal: which modal profile does that (statue-shaped) object have? Does it have the modal profile of a statue, a lump, a mere aggregate? On a hylomorphic view the hard question is ontological: which objects exist? Does a statue (matter-m + statue-form), a (...) lump (matter-m + lump-form), and/or a mere aggregate (matter-m + mere aggregate-form) exist? I defend a novel answer to the hard question for hylomorphism. In particular, I argue that which ordinary objects exist depends, in part, on how subjects respond to the matter they encounter. I argue that, with regard to grounding the existence and modal properties of ordinary objects, response-dependent hylomorphism is superior to both matter only views and to non-response-dependent versions of hylomorphism. (shrink)

How can a statue and a piece of alloy be coincident at any time at which they exist and yet differ in their modal properties? I argue that this question demands an answer and that the only plausible answer is one that posits a difference in the form of the two objects.

In the face of the puzzles of material constitution, some philosophers have been moved to posit a distinction between an object's matter and its form. A familiar difficulty for contemporary hylomorphism is to say which properties are eligible as forms: for example, it seems that it would be intolerably arbitrary to say that being statue shaped is embodied by some material object, but that other complex shape properties aren't. Anti-arbitrariness concerns lead quickly to a plenitudinous ontology. The usual complaint is (...) that the super-abundance of material objects is too extraordinary to accept, but I want to raise a different worry: I argue that the most natural way of developing this picture is already inconsistent. I show that a simple version of plenitudinous hylomorphism is subject to a Russellian argument, but argue that we cannot treat the problem straightforwardly as an instance of Russell's Paradox of Sets.

I explore the interrelations between the ontological and aesthetic issues raised by ready-mades such as Duchamp’s Fountain. I outline a hylomorphic metaphysics which has two central features. First, hylomorphically complex objects have matter to which they are not identical. Secondly, when such objects are artefacts (including artworks), it is essential to them that they are the products of creative work on their matter. Against this background, I suggest that ready-mades are of aesthetic interest because they pose a dilemma. Is there (...) really an object, a sculpture, that is distinct from its matter, a urinal, which object is created merely by the artist’s choice of the urinal? Or are we dealing with a case in which an artist passes off something, a urinal, as if it were a sculpture, even though it is not one? (shrink)

I compare a Lewisian defence of monism with Kit Fine's defence of pluralism. I argue that the Lewisian defence is, at present, the clearer in its explanatory intent and ontological commitments. I challenge Fine to explain more fully the nature of the entities that he postulates and the relationship between continuous material objects and the parts of those rigid embodiments in terms of which he proposes to explain crucial, modal and sortal, features of those objects.

Simon J. Evnine explores the view that some objects have matter from which they are distinct but that this distinctness is not due to the existence of anything like a form. He draws on Aristotle's insight that such objects must be understood in terms of an account that links what they are essentially with how they come to exist and what their functions are. Artifacts are the most prominent kind of objects where these three features coincide, and Evnine develops a (...) detailed account of the existence and identity conditions of artifacts, and the origins of their functions, in terms of how they come into existence. He then extends this account to organisms, where evolution accomplishes what is effected by intentional making in the case of artifacts, and to actions, which are seen as artifactual events.

William Jaworski shows how hylomorphism can be used to solve mind-body problems--the question of how thought, feeling, perception, and other mental phenomena fit into the physical world. Hylomorphism claims that structure is a basic ontological and explanatory principle, and is responsible for individuals being the kinds of things they are, and having the powers or capacities they have. From a hylomorphic perspective, mind-body problems are byproducts of a worldview that rejects structure, and which lacks a basic principle which distinguishes the (...) parts of the physical universe that can think, feel, and perceive from those that can't. Without such a principle, the existence of those powers in the physical world can start to look inexplicable and mysterious. But if mental phenomena are structural phenomena then they are uncontroversially part of the physical world. Hylomorphism thus provides an elegant way of solving mind-body problems. (shrink)

One of the central questions of material-object metaphysics is which highly visible objects there are right before our eyes. Daniel Z. Korman defends a conservative view, according to which our ordinary, natural judgments about which objects there are are more or less correct. He begins with an overview of the arguments that have led people away from the conservative view, into revisionary views according to which there are far more objects than we ordinarily take there to be or far fewer. (...) Korman criticizes a variety of compatibilist strategies, according to which these revisionary views are actually compatible with our ordinary beliefs. He goes on to respond to debunking arguments; objections that the conservative's verdicts about which objects that are and aren't are objectionably arbitrary; the argument from vagueness; the overdetermination argument; the argument from material constitution; and the problem of the many.

The objects we encounter in ordinary life and scientific practice - cars, trees, people, houses, molecules, galaxies, and the like - have long been a fruitful source of perplexity for metaphysicians. The Structure of Objects gives an original analysis of those material objects to which we take ourselves to be committed in our ordinary, scientifically informed discourse. Koslicki focuses on material objects in particular, or, as metaphysicians like to call them "concrete particulars", i.e., objects which occupy a single region of (...) space-time at each time at which they exist and which have a certain range of properties that go along with space-occupancy, such as weight, shape, color, texture, and temperature. The Structure of Objects focuses in particular on the question of how the parts of such objects, assuming that they have parts, are related to the wholes which they compose. (shrink)

Aristotle famously held that objects are comprised of matter and form. That is the central doctrine of hylomorphism (sometimes rendered “hylemorphism”—hyle, matter; morphe, form), and the view has become a live topic of inquiry today. Contemporary proponents of the doctrine include Jeffrey Brower, Kit Fine, David Hershenov, Mark Johnston, Kathrin Koslicki, Anna Marmodoro, Michael Rea, and Patrick Toner, among others. In the wake of these contemporary hylomorphic theories the doctrine has seen application to various topics within mainstream analytic metaphysics. Here, (...) appeals to form and matter are used to shed light on problems about ontology, personal identity, philosophy of mind, and philosophy of religion. The current entry documents this resurgence of interest in hylomorphism, the ways it has been applied, and its reception. (shrink)
