Most contemporary metaphysicians are sceptical about the reality of familiar objects such as dogs and trees, people and desks, cells and stars. They prefer an ontology of the spatially tiny or temporally tiny. Tiny microparticles 'dog-wise arranged' explain the appearance, they say, that there are dogs; microparticles obeying microphysics collectively cause anything that a baseball appears to cause; temporal stages collectively sustain the illusion of enduring objects that persist across changes. Crawford L. Elder argues that all such attempts to 'explain (...) away' familiar objects project downwards, onto the tiny entities, structures and features of familiar objects themselves. He contends that sceptical metaphysicians are thus employing shadows of familiar objects, while denying that the entities which cast those shadows really exist. He argues that the shadows are indeed really there, because their sources - familiar objects - are mind-independently real. (shrink)

In _Real Natures and Familiar Objects_ Crawford Elder defends, with qualifications, the ontology of common sense. He argues that we exist -- that no gloss is necessary for the statement "human beings exist" to show that it is true of the world as it really is -- and that we are surrounded by many of the medium-sized objects in which common sense believes. He argues further that these familiar medium-sized objects not only exist, but have essential properties, which we are (...) often able to determine by observation. The starting point of his argument is that ontology should operate under empirical load -- that is, it should give special weight to the objects and properties that we treat as real in our best predictions and explanations of what happens in the world. Elder calls this presumption "mildly controversial" because it entails that arguments are needed for certain widely assumed positions such as "mereological universalism". Elder begins by defending realism about essentialness. He then defends this view of familiar objects against causal exclusion arguments and worries about vagueness. Finally, he argues that many of the objects in which common sense believes really exist, including artifacts and biological devices shaped by natural selection, and that we too exist, as products of natural selection.

This paper argues that typical biological species are natural kinds, on a familiar realist understanding of natural kinds—classes of individuals across which certain properties cluster together, in virtue of the causal workings of the world. But the clustering is far from exceptionless. Virtually no properties, or property-combinations, characterize every last member of a typical species—unless they can also appear outside the species. This motivates some to hold that what ties together the members of a species is the ability to interbreed, (...) others that it is common descent. Yet others hold that species are scattered individuals,of which organisms are parts rather than members. But not one of these views absolves us of the need to posit a typical phenotypic profile. Vagueness is here to stay. Some seek to explain the vagueness by saying species are united by “homeostatic property clusters”; but this view collapses into the more familiar realist picture.

Historically, opponents of realism have managed to slip beneath a key objection which realists raise against them. The opponents say that some element of the world is constructed by our cognitive practices; realists retort that the element would have existed unaltered, had our practices differed; the opponents sometimes agree, contending that we construct in just such a way as to render the counterfactual true. The contemporary instalment of this debate starts with conventionalism about modality, which holds that the borders of (...) the world's kinds and the careers of individuals in those kinds obtain only relative to our conventions of individuation. Realists object that the kinds and careers in nature would still have obtained, had our conventions been different, but conventionalists claim to be able to agree. I argue that this claim is false, and that conventionalism contradicts itself. (shrink)

The modern form of realism about properties has typically been far more austere than its Platonic ancestor. There is nothing especially austere about denying, as most modern property realists do, the reality of “disjunctive properties”—properties which would correspond, in the world, to disjunctive predicates such as “is an apple or an ocean,” “is observed by now and green or not observed by now and blue,” etc. But modern property realists typically deny far more. It has been argued, for example, that (...) the only real properties there are are properties flanked by contrary opposites—so that there is no real property corresponding, for example, to the predicate “is self-identical.” Perhaps the biggest step in the direction of austerity is the argument, offered by a number of modern property realists, that there can be in the world no “determinable properties” corresponding to such determinable predicates as “has mass,” “is colored,” or “has a valence.” For these arguments are said to establish that not even such familiar properties as redness or painfulness really exist; to predicates such as “is red” and “is painful,” no real property corresponds. The business of this paper is to examine the prevailing arguments against “determinable properties,” and to argue that the ontology which they entail is decidedly less austere than is commonly supposed. The motivation is mainly just to get a more accurate ontology of properties. But a side benefit, if my arguments are correct, will be an increased appreciation for the treatment of vague predicates that posits truth-value gaps—and with it, increased ease with the idea that corresponding to vague predicates there really are, in the world, vague properties.

Historically, opponents of realism have argued that the world’s objects are constructed by our cognitive activities—or, less colorfully, that they exist and are as they are only relative to our ways of thinking and speaking. To this realists have stoutly replied that even if we had thought or spoken in ways different from our actual ones, the world would still have been populated by the same objects as it actually is, or at least by most of them. (Our thinking differently (...) could cause some differences in which objects exist, or in what some existing objects are like, but that is another matter.) Yet this reply has repeatedly failed to amount to a decisive objection. For opponents of realism have repeatedly argued, in one way or another, that we construct the world’s objects in just such a way as to render such a counterfactual true. We construct them so as to appear not to be our constructs. Just such a debate is currently underway concerning the properties that are essential to the world’s objects. It is widely agreed, with varying caveats1, that there are such properties—that by virtue of belonging to one or another natural kind, the world’s objects possess certain properties essentially, and have individual careers that last exactly as long as those essential properties are jointly present. But what underlies the status as essential of the properties that are thus essential to objects in the world? The realist answer treats essential status as mind-independent, and assigns it to the way the world works (Elder.. (shrink)

James decides that the best price today on pork chops is at Supermarket S, then James makes driving motions for twenty minutes, then James’ car enters the parking lot at Supermarket S. Common sense supposes that the stages in this sequence may be causally connected, and that the pattern is commonplace: James’ belief (together with his desire for pork chops) causes bodily behavior, and the behavior causes a change in James’ whereabouts. Anyone committed to the idea that beliefs and desires (...) are states installed by evolution must, it seems, think something similar. For how can one see beliefs and desires as conferring selective advantage if not by supposing that, by causing bodily behavior in their subjects, they brought about changes in their subjects’ surroundings? Yet many, many philosophers currently think or worry that mental causation is illusory (see, e.g., Heil and Mele 1993, or Macdonald and Macdonald 1995). Any physical changes which a mental state appears to cause can be viewed as a complex event involving microparticles, and for any such complex event, many philosophers suppose, there will have been previous microphysical occurrences sufficient to cause it. Barring routine overdetermination of such complex events, the apparent causation of mental events seems to be excluded. Nor does it help to say that some salient segment of the previous microphysical event just is the mental event, differently described (Davidson 1970). For describing the previous events as microphysical seems to spotlight the very features in virtue of which they did their causal work; the mental features seem epiphenomenal (Yablo 1992b: pp. 425-36; Yablo 1992a). This paper argues that the complex physical events, which mental events seem excluded from causing, are not caused at all. For they are either accidents, in something like Aristotle’s sense (Sorabji 1980: pp. 3-25), or coincidences, in a sense which David Owens has recently sharpened (Owens 1992). (shrink)

Common sense supposes thoughts can cause bodily movements and thereby bring about changes in where the agent is or how his surroundings are. Many philosophers suppose that any such outcome is realized in a complex state of affairs involving only microparticles; that previous microphysical developments were sufficient to cause that state of affairs; hence that, barring overdetermination, causation by the mental is excluded. This paper argues that the microphysical swarm that realizes the outcome is an accident or a coincidence and (...) has no cause, though each component movement in it has one. Mental causation faces no competition "from below". (shrink)

A mutation alters the hemoglobin in some members of a species of antelope, and as a result the members fare better at high altitudes than their conspecifics do; so high-altitude foraging areas become open to them that are closed to their conspecifics; they thrive, reproduce at a greater rate, and the gene for altered hemoglobin spreads further through the gene pool of the species. That sounds like a classic example (owed to Karen Neander, 1995) of a causal chain traced by (...) evolutionary biology. But a view now nearly universal among philosophers maintains that such biological causation is always shadowed, perhaps even rivaled, by causation on a different level.1 That the subgroup of antelopes forages in areas closed to the conspecifics is a state of affairs embodied or realized, notes this view, in certain movements and state changes done by certain physical microparticles—untold billions of microparticles and movements, but a finite and determinate (more on this below) collection nevertheless. That the subgroup reproduces at a greater rate is likewise realized by a huge collection of microparticle movements, a different collection. And the microparticle happenings comprised in the first collection are causally responsible, strictly in accordance with the laws of microphysics, for the microparticle happenings in the second. Biological causation is always shadowed, perhaps even rivaled, by causation on the level of microphysics. The view I mean is general: any case of causing uncovered by any of the special sciences can be recaptured at the level of microphysics. This view is I think what most philosophers mean by “physicalism”; in any case, “physicalism” is the label I shall use. Physicalism comes in two forms. Modest physicalism holds that any causal transaction reported by the special sciences can be retraced by microphysics.2 Hegemonic physicalism holds that retracing such a transaction at the level of..

An influential line of thought in metaphysics holds that where common sense discerns a tree or a dog or a baseball there may be just many microparticles. Provided the microparticles are arranged in the right way -- are “treewise” or “dogwise” or “baseballwise” arranged -- our sensory experiences will be just the same as if a tree or dog or baseball were really there. Therefore whether there really are suchfamiliar objects in the world can be decided only by determining what (...) more is needed for microparticles dogwise arranged actually to compose a dog. This paper argues that this line of thought sets up the wrong agenda. Composition is trivial; dogwise (etc.) arrangement is tricky. Dogwise arrangement will obtain in the wrong regions unless we stipulate that there are dogs, and that dogwise arrangementobtains only within their borders. The bearers of dogwise arrangement, moreover, will have to be dogs themselves, not their microparticles. Thus allowing that dogwise arrangement obtains at all is allowing that there are dogs.

How can a parcel of matter, or collection of particles, simultaneously compose three different objects, characterized by different modal properties? If the statue is gouged it still exists, but not exactly that piece of gold which originally occupied the statue's borders, and the gold within that piece can survive dispersal, while the piece cannot. The solution to this "problem of coinciding objects", this paper argues, is that there is, in that space, only the statue. The properties which the piece and (...) the mass supposedly must have, to go on being, are not properties which anything can have necessarily or essentially. Not even having that origin can be essential. There is no object of which the statue is composed, though there are objects and a kind of stuff of which it is composed. (shrink)

We are confident of many of the judgements we make as to what sorts of alterations the members of nature's kinds can survive, and what sorts of events mark the ends of their existences. But is our confidence based on empirical observation of nature's kinds and their members? Conventionalists deny that we can learn empirically which properties are essential to the members of nature's kinds. Judgements of sameness in kind between members, and of numerical sameness of a member across time, (...) merely project our conventions of individuation. Our confidence is warranted because apart from those conventions there are no phenomena of kind-sameness or of numerical sameness across time. There is just 'stuff' displaying properties. This paper argues that conventionalists can assign no properties to the 'stuff' beyond immediate phenomenal properties. Consequently they cannot explain how each of us comes to be able to wield 'our conventions'. (shrink)

Common sense believes in objects which, if real, routinely lose component parts or particles. Statues get chipped, people undergo haircuts and amputations, and ships have planks replaced. Sometimes philosophers argue that in addition to these objects, there are others which could not possibly lose any of their parts or particles, nor have new ones added to them--objects which could not possibly have been bigger or smaller, at any time, than how they actually were.1 (Sometimes the restriction on size is argued (...) independently of the restriction on switches of parts.2) If these other objects are real at all, they are alarmingly abundant. Exactly where the statue sits, there sits a parcel or piece of clay which would cease to be itself, and hence cease to exist, were even so small a part as the statue's nose removed.3 In exactly the place where the recently reconditioned ship is found, there is a mass of wood which never contained, and never could contain, any particles of wood--or bits of wood-stuff--other than those it now has.4 Moreover, since masses of matter (or "aggregates") can continue to exist even if divided into separate parts, while parcels cannot, the abundance is two-fold: where every parcel is found, there is also a mass.5 But how can there be room for all these additional objects if, at any time, two different objects cannot occupy exactly the same place? Or, worse, if even some of these additional objects are real, how can room remain for familiar objects? Recent treatments of this ancient puzzle have urged that we retain both "the principle of one object to a place" and the other ontological assumptions which make that principle seem to force a choice between affirming the reality of familiar objects, and that of the strangely brittle intruders.6 But all the recent treatments have left standing the reality of at least some of these brittle objects.7 By doing so they have passed up what is, perhaps, the simplest and safest response to the ancient puzzle..

When a tree is chopped to bits, or a sweater unravelled, its matter still exists. Since antiquity, it has sometimes been inferred that nothing really has been destroyed: what has happened is just that this matter has assumed new form. Contemporary versions hold that apparent destruction of a familiar object is just rearrangement of microparticles or of 'physical simples' or 'world stuff'. But if destruction of a familiar object is genuinely to be reduced to mere alteration of something else, we (...) must identify an alteration proper to the career, the course of existence, of this something else; relatedly, the alteration must be characterizable without asserting the existence of the familiar object. All contemporary views fail one of these requirements. (shrink)

To be a realist about modality, need one claim that more exists than just the various objects and properties that populate the world—e.g. worlds other than the actual one, or maximal consistent sets of propositions? Or does the existence of objects and properties by itself involve the obtaining of necessities (and possibilities) in re? The latter position is now unpopular but not unfamiliar. Aristotle held that objects have essences, and hence necessarily have certain properties. Recently it has been argued that (...) the identity of any property is tied to the natural laws in which it figures, which entails that the occurrence of properties involves the obtaining of nomological necessities ([24], pp. 206-33 and 234-60; [23]; cf. [25] and [6]). Somewhat less recently, Wittgenstein ([28], p. 168) worried that the reality of at least some properties—precise shades of colors being a prime example—involved the obtaining in re of certain impossibilities. This paper argues that Wittgenstein’s worries were right, and not just concerning some properties, but all properties whatever. That there are objects and properties in the world at all, then, amounts to there obtaining modal states of affairs. This argument supplements, rather than replaces, the others. The position on property incompatibility advanced here actually helps defend Aristotelian essentialism against epistemological objections, or so I have argued ([15]). And while this paper’s position on property incompatibility diverges from the idea that a property’s nomic profile is essential to it—more on this in the next section—it is at least compatible with the thought that the necessity involved in the laws of nature enters into ontology at the ground level.

Empty judgements appear to be about something, and inaccurate judgements to report something. Naturalism tries to explain these appearances without positing non-real objects or states of affairs. Biological naturalism explains that the false and the empty are tokens which fail to perform the function proper to their biological type. But if truth is a biological 'supposed to', we should expect designs that achieve it only often enough. The sensory stimuli which trigger the frog's gulp-launching signal may be a poor guide (...) to the signal's content. Teleosemantics should be anti-verificationist. (shrink)

Are judgements and wishes really brain events which will be affirmed by a completed scientific account of how human behavior is caused? Materialists, other than eliminativists, say Yes. But brain events do not cause muscle contractions, hence bodily movements, directly. They do so, if at all, by triggering intermediate causes, viz. firings in motor nerves. So it is crucial, this paper argues, whether they are characterized as biological events - performances of naturally-selected-for operations - or instead as complex microphysical events. (...) "A causes B, B causes C, so A causes C" is defensible for biological brain events, but fails for "microphysical" ones. (shrink)

This book presents vigorous and wide-ranging arguments in defense of an Aristotelian metaphysical scheme along fairly orthodox Thomistic lines. The central claim is that the items that populate the world have real essences – natures that mind-independently define what each such item is. This Aristotelian essentialism, Oderberg begins by telling us, is a different doctrine from what has recently been called ‘essentialism’, and a more powerful one . For recent essentialism has treated a thing's essence as merely all those properties (...) that the thing takes with it across all possible worlds – and here modality gets presupposed in order to explain essentialness, when the order should be reversed.We can observe essences, Oderberg holds, even though the observation is indirect, and even though knowing what to make of our observations requires applying metaphysical knowledge. Positivism-inspired worries that there is something unfactual about modal claims, and hence about essences, are unfounded . Claims about essences do have factual content, but not because they merely express our concepts or our grammar, and not because they simply report empirical findings . True reports of the essences of objects articulate a metaphysical insight from Aristotle: an object's essence is a compound of its substantial form and its prime matter . Its form actuates potentialities of its matter . The laws of nature derive from essences, and hence are necessary rather than contingent . Artifacts are ‘accidental unities’ of individual substances and …. (shrink)

More laws obtain in the world,it appears, than just those of microphysics –e.g. laws of genetics, perceptual psychology,economics.

How can themicroparticles in such an object lawfully domore than what is required of them by the lawsof microphysics? Are there additional laws formicroparticles – which seems to violate closureof microphysics – or is the ``more'' (...) acoincidental outcome of microphysics itself?

This book stakes out a position in the area of metaphysics that deals with modality. But is this even a legitimate area of inquiry? Chapter 1 begins by confronting scepticism on this score. Some hold that the logical positivists sharpened “Hume’s fork”— either “relations of ideas” or “matters of fact”—and thereby discredited metaphysics in general. Others hold that Wittgenstein discredited the specific metaphysical position known as essentialism. But both readings of the record are mistaken, McLeod argues. Hume did not himself (...) oppose metaphysics in general; he affirmed the value of “abstruse metaphysics”, and considered himself a practitioner. Positivist elaborations of Hume’s fork moreover were not enough to indict metaphysics in general. As for Wittgenstein, he himself engaged in essentialist speculation in the Tractatus. His question there was what about the world explains that the world is capable of being represented. The only answer possible must point to what the world by nature is like. (shrink)

It is widely supposed that, in Hilary Putnam’s phrase, there are no “ready-made objects” (Putnam 1982; cf. Putnam 1981, Ch. 3). Instead the objects we consider real are partly of our own making: we carve them out of the world (or out of experience). The usual reason for supposing this lies in the claim that there are available to us alternative ways of “dividing reality” into objects (to quote the title of Hirsch 1993), ways which would afford us every bit (...) as much practical and cognitive mastery as we now possess. Hence there is no warrant for supposing that the objects recognized by such alternative schemes are any less real than the objects we actually consider real—unless we are to appeal to a “God’s-eye perspective”, which virtually no one wants to do. The reasonable conclusion, many philosophers suppose, is that any system of objects exists only relative to a particular conceptual scheme or system of predicates. Our system of objects is, in this sense, partly of our own making. But this claim should not be heard as a reaffirmation of the idealism of Fichte or Husserl. It is more accurate to take it merely as a claim about sameness and difference among the objects of the world. It is the claim that sameness and difference, whether at the level of kinds or of individual objects, do not obtain mind-independently, but only relative to a conceptual scheme or predicate system (see, e.g., Putnam 1981, pp. 53-54). That is, whether two objects are of the same kind, and whether one and the same individual object now exists at such-and-such.. (shrink)

Here is a view at least much like Lewis’s “Humean supervenience,” and in any case highly influential—in that some endorse it, and many more worry that it is true. All truths about the world are fixed by the pattern of instantiation, by individual points in space-time, of the “perfectly natural properties” posited by end-of-inquiry physics. In part, this view denies independent variability: the world could not have been different from how it actually is, in the ways depicted by common sense (...) and the special sciences, without differing in the punctiform instantiation of fundamental physical properties. In part, it makes an ontological claim: what it is for one of the objects recognized by common sense or special sciences to be there in the world, bearing the properties attributed by a true description, is “nothing over and above” the obtaining of fundamental physical properties at points, and fundamental physical relations among points. I argue that this view is untenable. I concede that for every true claim in familiar discourses, there is a state of affairs at the level of fundamental microphysics that is the truth-maker—some state of affairs sufficient for truth in the familiar claim. The problem is that the view needs to posit not just truth-makers at the level of microphysics, but truth-conditions—states of affairs the obtaining of which is required for truth in any familiar claim, and the failure of which renders the familiar claim false. That is, the view must posit necessary conditions, at the level of microparticles, for truth in familiar claims. This it cannot plausibly do. (shrink)

This paper argues that there can be, For each individual mental state, Some identifiable neural "embodiment" only if the brain operates in accord with a hegelian teleological model. "embodiments" are neural configurations which do, Or would, Produce all the behaviors connected with the mental state. The argument hinges on how these behaviors are described: if under predicates of neurophysics only, Then only under wildly disjunctive predicates, Which cannot be projected for any candidate configuration; if under "teleological" predicates, Then under predicates (...) projectible for teleological hardware. Hegel's logic provides for a teleology consistent with modern science. (shrink)

What caused the event we report by saying “the window shattered”? Was it the baseball, which crashed into the window? Causal exclusionists say: many, many microparticles collectively caused that event—microparticles located where common sense supposes the baseball was. Unitary large objects such as baseballs cause nothing; indeed, by Alexander’s dictum, there are no such objects. This paper argues that the false claim about causal efficacy is instead the one that attributes it to the many microparticles. Causation obtains just where there (...) is an “invariance”, a true generalization to the effect that had things been different with the putative cause, things would have been correspondingly different with the putative effect. But “correspondingly” here requires a rough metric. There must be a fact as to which alternative group events, involving many microparticles, would have departed less from the putative cause of the shattering, and which would have departed more. Surprisingly, there is no such fact. (shrink)

“Spirit,” Hegel writes in par. 389 of the Encyclopaedia, “is the existent truth of matter—the truth that matter itself has no truth.” The same claim is made in more understandable form in the Zusatz which follows: “the material, which lacks independence in the face of spirit, is freely pervaded by the latter which overarches this its Other,” reducing this Other “to an ideal moment and to something mediated.” Philosophers who have written on Hegel will recognize these passages as ones which (...) call for a fair amount of exegesis. The issue I want to raise in this paper is rather different: just what argument does Hegel supply to establish that Spirit indeed is, as claimed, “the truth of,” or central to, the material world? What reason is given to show that we readers should agree that “the material has absolutely no meaning beyond that of being a negative over against spirit and over against itself?” I shall begin by considering one of the clearer answers to this question offered in recent literature on Hegel. I then shall discuss at much greater length how this answer requires to be supplemented. (shrink)

Can an ontology which treats properties as really out there in the world be combined vvith the view that necessity is not out there? What about the necessity by which redness excludes greenness, or weighing 8 kg excludes weighing 6 kg?
