Teleological Essentialism

Placeholder essentialism is the view that there is a causal essence that holds category members together, though we may not know what the essence is. Sometimes the placeholder can be filled in by scientific essences, such as when we acquire scientific knowledge that the atomic weight of gold is 79. We challenge the view that placeholders are elaborated by scientific essences. In our view, if placeholders are elaborated, they are elaborated by Aristotelian essences, a telos. Utilizing the same kind of experiments used by traditional essentialists—involving superficial change (study 1), transformation of insides (study 2), acquired traits (study 3), and inferences about offspring (study 4)—we find support for the view that essences are elaborated by a telos. And we find evidence (study 5) that teleological essences may generate category judgments.     

De re modality,generic essences,and science

Conclusion I have taken the traditional problem of the seeming interdependence of identity concepts and essentialistic concepts and the attendant difficulties with circularity as a starting point in my consideration of recent attempts to provide accounts ofde re essences. Having distinguished between theories of individual and generic essences, I have shown how a linguistic device based upon a new approach to referring expressions has, perhaps, provided some advance in the understanding of individualde re essences. I have argued that, however efficacious these linguistic devices may be in dealing with individual essences, they are of no help in dealing with generic essences. I considered, therefore, one of the recent attempts to use science as the arbiter ofde re essences and concluded that such attempts will not, ultimately, solve the traditional problem of circularity. That problem remains, arising in different forms to thwart different attempts to account forde re generic essences.     

An essentialism perspective on intercultural processes

Essentialist theories are the beliefs that there are immutable essences underlying observed differences between social groups (e.g. racial group, cultural group). This paper reviews the intergroup dynamics and intrapersonal processes associated with essentialism. It also explores the interplay between the two. By explicating the intricate relationship between these psychological processes, the current paper aims to advance our understanding of intergroup relations and identify their implications for the study of multiculturalism. We posit that although the commonly observed negative intergroup outcomes, such as prejudices and biases, can be the byproducts of basic cognitive processes associated with essentialist theories, the social power dynamics in a given society also play important roles in shaping the relationships between essentialism and intergroup outcomes. We then discuss the implications of this understanding to our increasingly multicultural world.     

Authority and Natural Kind Essence

If natural kinds have microstructural essences they have them independently of rules for the application of kind terms. This suggests that what those rules are should make no difference to the essences being discoverable. I present two thought-experiments that suggest otherwise, however. Each shows an authority’s application of rules creates the appearance of there being kind essences; absent those rules, the appearance vanishes. This suggests natural kind essences are not independent of authority-sanctioned rules.     

Natural Kinds of Substance

This paper presents an extension of Putnam's account of how substance terms such as ‘water’ and ‘gold’ function and of how a posteriori necessary truths concerning the underlying microstructures of such kinds may be derived. The paper has three aims. (1) I aim to refute a familiar criticism of Putnam's account: that it presupposes what Salmon calls an ‘irredeemably metaphysical, and philosophically controversial, theory of essentialism’. I show how all of the details of Putnam's account—including those that Salmon believes smuggle in such essentialist commitments—can be squared with a rejection of any such essentialist metaphysics. (2) I aim to reveal why Steward is wrong to suppose that, by helping himself to the claim that ‘H₂O’ is a rigid designator of a substance, Kripke, too, presupposes something controversially ‘metaphysical’. (3) I aim to show how my proposed account also sidesteps a variety of objections raised by Needham and others who argue that Kripke's and Putnam's accounts of how ‘water’ and ‘gold’ function founder upon the sheer microstructural complexity of the phenomena in question.     

De Re Language,De Re Eliminability,and the Essential Limits of Both

De re modality is eliminable if there is an effective translation of all wffs into non-de re equivalents. We cannot have logical equivalence unless logic has odd theses, but we can have material equivalence by banning all essences, something the non-de re facts let us do, or by giving everything such humdrum essences as self-identity and banning the more interesting ones. Eliminability cannot be got from weaker assumptions, nor independent ones of even modest generality. The net philosophical import is that, quite apart from the merits of essentialism, de re language has scant utility.     

The Ontological Status of Cartesian Natures

Abstract: In the Fifth Meditation, Descartes makes a remarkable claim about the ontological status of geometrical figures. He asserts that an object such as a triangle has a 'true and immutable nature' that does not depend on the mind, yet has being even if there are no triangles existing in the world. This statement has led many commentators to assume that Descartes is a Platonist regarding essences and in the philosophy of mathematics. One problem with this seemingly natural reading is that it contradicts the conceptualist account of universals that one finds in the Principles of Philosophy and elsewhere. In this paper, I offer a novel interpretation of the notion of a true and immutable nature which reconciles the Fifth Meditation with the conceptualism of Descartes' other work. Specifically, I argue that Descartes takes natures to be innate ideas considered in terms of their so-called 'objective being'.     

LOOKING TO CHARLES TAYLOR AND JOSEPH ROUSE FOR BEST PRACTICES IN SCIENCE AND RELIGION

People discussing science and religion usually frame their conversations in terms of essentialist assumptions about science, assumptions requiring the existence (but not the specification) of criteria according to which science can be distinguished from other forms of inquiry. However, criteria functioning at a level of generality appropriate to such discussions may not exist at all. Essentialist assumptions may be avoided if science is understood within a broader context of human practices. In a philosophy of practices, to label a practice as “scientific” is to make a practically motivated provision for a way of speaking. Charles Taylor and Joseph Rouse have produced complementary philosophies of practice that promote this kind of understanding. In this essay I review the work of Taylor and Rouse, identify apparent residues of essentialism that each seems to harbor, and offer a resolution to some of their disagreements. I also criticize a form of essentialism commonly employed in Christian circles and outline an anti‐essentialist view of science that may be helpful in science‐and‐religion discussions.     

The Distinction between Reason and Intuitive Knowledge in Spinoza's Ethics

While both intuitive knowledge (scientia intuitiva) and reason (ratio) are adequate ways of knowing for Spinoza, they are not equal. Intuitive knowledge, which Spinoza describes as the ‘greatest virtue of mind’, is superior to reason. The nature of this superiority has been the subject of some controversy due to Spinoza's notoriously parsimonious treatment of the distinction between reason and intuitive knowledge in the Ethics. In this paper, I argue that intuitive knowledge differs from reason not only in terms of its method of cognition—but also in terms of its content. More specifically, I maintain that there is something that is known by intuition, namely the unique essences of things, that is not known by reason. My argument is supported by an examination of Spinoza's account of essences in the Ethics, which reveals that he is committed to both unique and shared essences. Based on this dual commitment, I argue that whereas for Spinoza both reason and intuition can be said to reach adequate knowledge of the shared essence of a thing, the unique essence of a singular thing, which is nothing but its actual essence, can only be known through intuitive knowledge.     

Putting modal metaphysics first

I propose that we approach the epistemology of modality by putting modal metaphysics first and, specifically, by investigating the metaphysics of essence. Following a prominent Neo-Aristotelian view, I hold that metaphysical necessity depends on the nature of things, namely their essences. I further clarify that essences are core properties having distinctive superexplanatory powers. In the case of natural kinds, which is my focus in the paper, superexplanatoriness is due to the fact that the essence of a kind is what causes all the many properties and behaviors that are typically shared by all the instances of the kind. Accordingly, we know what is necessarily true of kinds by knowing what is essential to them in the sense of actually playing such causal-explanatory roles. Modal reasoning aimed at discovering metaphysical necessity thus proceeds via essentialist deduction: we move from essentialist truths to reach necessary truths.

     

Spinoza on the Essences of Modes

This paper examines some aspects of Spinoza's metaphysics of the essences of modes.2 ²I would like to thank John Carriero, Calvin Normore, Eliot Michaelson, Eileen Nutting, Paul Nichols, Alexi Patsaouras, Rachel Johnson and Sarah Jansen for reading and commenting on earlier versions of this paper. I situate Spinoza's use of the notion of essence as a response to traditional, Aristotelian, ways of thinking about essence. I argue that, although Spinoza rejects part of the Aristotelian conception of essence, according to which it is in virtue of its essence that a thing is a member of a kind, he nevertheless retains a different part of such a conception, according to which an essence is some structural feature of a thing which causally explains other, non-essential features. I go on to develop an account of Spinoza's metaphysics of essence, according to which essences, what he sometimes calls formal essences, are produced by the divine essence prior to and independent of the creation of finite modes, and according to which essences are the formal or exemplar causes of finite modes. I then argue that finite modes, in virtue of the formal essences which they actualize, are genuine causal relata. Finally, I offer some speculations about Spinoza's answer to the question, ‘Why, in a necessitarian cosmos filled with formal essences, should there be temporal finite modes at all?’     

On the essence of empty properties

This paper deals with generalisations of modally based criteria for determining whether a given property is essential to an individual to the case of generic essences. These criteria usually presuppose extensionally individuated properties. The limitations of their generalisations are demonstrated using the case of the necessarily empty individual property and the necessarily empty individual office. I do not present a novel stance on the discussion of individual essences. The novelty of this paper lies in its claim that none of these criteria can be generalised to generic essences.

     

Grounding,physicalism and necessity

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.     

Much Ado About Nothing? Some Comments on B. F. Skinner's Definition of Verbal Behavior

Some have suggested that the definition of verbal behavior offered by B. F. Skinner (1957) fails to capture the essence of language insofar as it is too broad and not functional. In this paper, I argue that the ambiguities of Skinner's definition are not an indictment of it, and that suggestions to the contrary are problematic because they suffer a critical error of scientific reasoning. Specifically, I argue that (a) no clear definition of verbal behavior is possible because there is no natural distinction between verbal and nonverbal behavior; (b) attempts at an immutable definition are essentialistic; and (c) Skinner's functional taxonomy of language is in no way affected by the particulars of any definition of verbal behavior.     

The true and the false

A dispositional property is a tendency, or potency, to manifest some characteristic behaviour in some appropriate context. The mainstream view in the twentieth century was that such properties are to be explained in terms of more fundamental non-dispositional properties, together with the laws of nature. In the last few decades, however, a rival view has become popular, according to which some properties are essentially dispositional in nature, and the laws of nature are to be explained in terms of these fundamental dispositions. The supposed ability of fundamental dispositions to ground natural laws is one of the most attractive features of the dispositional essentialist position. In this paper, however, I cast doubt on the ability of dispositional essences to ground the laws of nature. In particular I argue that the dispositional essentialist position is not able to coherently respond—sympathetically or otherwise—to Cartwright's challenge that there are no true general laws of nature.     

Far Away Now: Time and Distance Revisited

Einstein claimed that we do not know what it means to say that events distant from one another are simultaneous, because there is no way to determine this operationally. Reichenbach and Grunbaum claimed that determinate time relations just do not exist among events not connectible by a causal signal and that, therefore, such relations can, within certain limits, be stipulated by convention. But I argue that the independent existence of such relations is demonstrated by asking and answering a series of questions based on the intelligibility, though not the existence, of faster-than-light signals. I further argue that (1) only by demonstrating the unintelligibility of such questions and their answers can the conventionality thesis be maintained; (2) none of the available arguments to show such unintelligibility works; and (3) the conventionality thesis is therefore false.     

Thinking chickens: a review of cognition,emotion, and behavior in the domestic chicken

Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in these areas with other birds and other vertebrates, particularly mammals. My overall conclusion is that chickens are just as cognitively, emotionally and socially complex as most other birds and mammals in many areas, and that there is a need for further noninvasive comparative behavioral research with chickens as well as a re-framing of current views about their intelligence.     

Rethinking the Ontology of Cartesian Essences

The old and recent debates on Cartesian essences have focused on the question of whether Descartes is a Platonist or a conceptualist about essences. I argue that this is a false dichotomy. An adequate account of Cartesian essences must accommodate and reconcile two central doctrines and texts in Descartes' philosophy. I will argue that recent conceptualist and Platonist interpretations neither accommodate these doctrines nor reconcile these texts. Such failures are not accidental since Descartes' doctrines of divine creation and simplicity render it impossible for Descartes to be either a conceptualist or a Platonist. Failure to notice this fact explains why there has been no progress on this exegetical issue.     

Revising the concept of lawhood: special sciences and natural kinds

The Kripkean conception of natural kinds (kinds are defined by essences that are intrinsic to their members and that lie at the microphysical level) indirectly finds support in a certain conception of a law of nature, according to which generalizations must have unlimited scope and be exceptionless to count as laws of nature. On my view, the kinds that constitute the subject matter of special sciences such as biology may very well turn out to be natural despite the fact that their essences fail to be microphysical or micro-based. On the causal conception of natural kinds I privilege, the naturalness of a kind is a function of the fact that it figures prominently in at least one causal law. However, there is a strong tendency prevailing among contemporary philosophers to assume that, in order to count as proper laws generalizations must be expectionless. Since most generalizations tracked down by the special sciences turn out not to fulfill these criteria, what this conception of a law implies is that most of the generalizations the special sciences trade in are not proper laws. It follows that, on this view, most if not all of the kinds the special sciences dealing with turn out not to constitute natural kinds, understood as kinds to which bona fide laws apply. In order to establish that the non-microstructurally defined kinds that fall within the domain of enquiry of the special sciences are eligible for the status of natural kind, I must therefore establish that generalizations needn’t have unlimited scope and be exceptionless to count as laws of nature. This is precisely what I seek to do in this paper. I begin by arguing that the question “what is a law of nature?” is most naturally interpreted as the question “what features must generalizations exhibit in order to ground scientific explanations?” and by offering reasons to believe that generalizations needn’t be exceptionless and have unlimited scope to play the crucial role laws have been thought to play in scientific explanation. Drawing on Sandra Mitchell [Mitchell, S. (2000). Philosophy of Science, 67, 242–265] and James Woodward’s [Woodward, J. (1997). Philosophy of science, 64 (proceedings), 524–541; Woodward, J. (2000). British Journal for the philosophy of science, 51(2), 197–254; Woodward, J. (2001). Philosophy of science, 68, 1–20] work, I subsequently develop an alternative account of the criteria generalizations must satisfy in order to count as laws of nature, which at least some of the generalizations of the special sciences turn out to fulfill. I thus give credence to the idea that at least some of the kinds that fall within the domain of the special sciences figure in laws of nature, and I thereby restore the possibility that some special science kinds deserve to be deemed natural.     

Knowing how things might have been

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will offer an account based on our knowledge of the natures, or essencess, of things. I will argue that essences need not be viewed as metaphysically bizarre entities; that we can conceptualise and refer to essences; and that we can gain knowledge of them. We can know about which properties are, and which properties are not, essential to a given entity. This knowledge of essence offers a route to knowledge of the ways those entities must be or could be.
