Kripke argues for origin essentialism, the view that the same individual cannot have multiple origins. Sober hypothesises that Kripke's origin essentialism applies to biological species. This paper shows that Sober's hypothesis fails. Because Kripke's original argument is invalid, it cannot vindicate Sober's proposal. Salmon offers an influential reformulation of Kripke's argument but his argument fails to extend to species: the notion of an individual's origin is too narrow to apply to species, and Salmon's argument rests (...) on a thought experiment that conflicts with how species evolve. Thus, Sober and others are wrong to think that Kripke's origin essentialism can save species essentialism. (shrink)

ln "Possibilities and the Arguments for Origin Essentialism" Teresa Robertson (1998) contends that the best-known arguments in favour of origin essentialism can succeed only at the cost of violating modal common sense—by denying that any variation in constitution or process of assembly is possible. Focusing on the (Kripke-style) arguments of Nathan Salmon and Graeme Forbes, Robertson shows that both founder in the face of sophisticated Ship of Theseus style considerations. While Robertson is right that neither of (...) the arguments is compelling as formulated, each can be modified to fend off her particular counterexamples; these modifications do not differ in kind from those already needed to deal with ordinary Theseus cases, requiring only a further narrowing of the sufficiency clause from which the necessity of origins is derived.

Origin essentialism gained prominence following Saul Kripke's endorsement of the view in Naming and Necessity. Since Kripke, several authors have developed arguments for origin essentialism; yet, no argument currently on offer adequately defends the view. In this thesis, I examine four arguments for origin essentialism and argue that each is unsuccessful. I offer a counter-model against the view that origin essentialism is a consequence of Kripke's work in Naming and Necessity. I show (...) that Nathan Salmon's refinement of Kripke's argument for origin essentialism fails because it assumes an implausible principle. I discuss Graeme Forbes's argument, which proceeds from the assumptions of the necessity of identity and that there are no bare truths concerning identity, and show that origin essentialism is not a consequence of those assumptions. Lastly, I show that a branching model of possibility fails as a basis for a persuasive defence of origin essentialism due to implausible consequences. (shrink)

Few discussions of the ethics of mitochondrial ‘replacement’ techniques have drawn significant ethical distinctions between the two approaches now legal in the U.K. However, Anthony Wrigley, Stephen Wilkinson and John Appleby have together argued that under some circumstances pronuclear transfer (PNT) may be in better ethical standing than maternal spindle transfer (MST). They base their conclusion on what they allege to be different implications of the techniques with respect to non‐identity considerations, which they ground on a version of origin (...) essentialism. I raise a series of problems for their argument, which have cautionary implications for invocations of origin essentialism that go beyond specialized debates regarding MST and PNT. I argue that (i) origin essentialism is a fragile foundation for non‐identity considerations; (ii) gametic essentialism, which Wrigley et al. believe licenses their claims, is more questionable than origin essentialism; (iii) gametic essentialism does not straightforwardly justify their conclusion; and (iv) their conclusion in fact relies on an especially dubious position that we can call chromosomal origin essentialism. No good reasons have yet been supplied to distinguish PNT from MST on ethical grounds, and one should be wary of basing claims with practical impact on fragile foundations relating to origin essentialism.

In his commentary on Aristotle’s De generatione et corruptione Marsilius of Inghen defends the view—unusual in the Middle Ages—that there is no such thing as intermittent or “gappy” existence. Even God cannot restore things that have been corrupted. This paper examines Marsilius’s unusual position, connecting them to another view he defends, namely that a thing’s origins—and in particular the time at which it comes about—are essential to its numerical identity as the particular individual it is. I consider John Buridan and (...) Nicole Oresme’s influence upon Marsilius’s views, and ultimately evaluate their plausibility, drawing on some recent work of Gyula Klima’s on gappy existence in Thomas Aquinas. (shrink)

Does natural selection explain why individual organisms have the traits that they do? According to "the Negative View," natural selection does not explain why any individual organism has the traits that it does. According to "the Positive View," natural selection at least sometimes does explain why an individual organism has the traits that it does. In this paper, I argue that recent arguments for the Positive View fail in virtue of running afoul of the doctrine of origin essentialism (...) and I demonstrate that other recent defenses of the Negative View depend upon my own for their plausibility.

In the last 30 years repeated attempts have been made to develop a proof-sketch Kripke gave for essentialism about material origins into a cogent argument. I argue that there are general reasons that all such attempts have failed, and so we should likewise expect future attempts to fail.

In a famous footnote in Naming and Necessity, Kripke offered “something like a proof” of the thesis that material things have their material origins essentially (EMO). Although the sketch of a proof Kripke gave was incomplete in important respects, many philosophers have since endeavoured to develop Kripke’s style of argument so that it reaches its intended conclusion.1 In particular, a number of philosophers have attempted to complete Kripke’s argument sketch by appealing to some sort of “sufficiency principle” – a principle (...) that gives sufficient conditions for the identity of objects across possible worlds. These developments of Kripke’s argument face a number of problems, as pointed out by Mackie (1987, 2002), Robertson (1998, 2000) and others.2 Recently, however, Rohrbaugh and deRosset (2004, 2006) have offered a new route to origin essentialism that develops a Kripke-style argument without appeal to a sufficiency principle. While this argument has also not escaped criticism3, the argument suffers from a crucial flaw which has not been noticed. More interesting, though, is that the problem the argument faces is the same problem facing the arguments that appeal to sufficiency principles, and indeed Kripke’s original “proof” – all these arguments over-generalize. This strongly suggests that there is no Kripkestyle route to origin essentialism. (shrink)

In this paper, I examine the case that has been made for origin essentialism and find it wanting. I focus on the arguments of Nathan Salmon and Graeme Forbes. Like most origin essentialists, Salmon and Forbes have been concerned to respect the intuition that slight variation in the origin of an artifact or organism is possible. But, I argue, both of their arguments fail to respect this intuition. Salmon's argument depends on a sufficiency principle for cross-world (...) identity, which should be rejected, if - as Salmon concedes - a given artifact might have been originally made from slightly different material. Similarly, Forbes's argument succeeds only if essentially the same argument can be used to establish a claim that - by his own admission - is too strong, namely that no variation, however slight, in an organism's origin is possible.

I explore options for a plenitudinarian solution to the Paradox of Flexible Origin Essentialism, taking as my unlikely starting point the views of Sarah-Jane Leslie, who holds that if plenitudinarianism is true, then there is in fact no paradox to be solved, only the illusion of one. The first three sections are expository: Sect. 1 on plenitudinarianism, Sect. 2 on the paradox, and Sect. 3 on Leslie’s views about how plenitudinarianism bears on the paradox. In Sect. 4, I (...) reject the contention that there is no paradox and critically explore three options for a plenitudinarian solution. In Sect. 5, I argue that the plenitudinarian ought to endorse a fourth option. In Sect. 6, I consider an objection. I endorse neither plenitudinarianism nor its denial; the main aim of the paper is to argue that for one who does endorse plenitudinarianism, the best solution to the Paradox of Flexible Origin Essentialism is clear.

In ordinary language, in the medical sciences, and in the overlap between them, we frequently make claims which imply that we might have had different gametic origins from the ones we actually have. Such statements seem intuitively true and coherent. But they counterfactually ascribe different DNA to their referents and therefore contradict material-origin essentialism, which Kripke and his followers argue is intuitively obvious. In this paper I argue, using examples from ordinary language and from philosophy of medicine and (...) bioethics, that statements which attribute alternative material origins to their referents are useful, common in political and medical reasoning, and in many cases best interpreted literally. So we must replace the doctrine of material-origin essentialism with one that can make sense of ordinary discourse and the language of the medical sciences. I propose an anti-essentialist account of such counterfactuals according to which individuals’ modal properties are relative to a given inquiry. (shrink)

My account is subject to two important limitations. First, I shall be discussing whether or not Aristotle holds to an essentialistic doctrine with regard to sensible particulars, and shall neglect entirely his views about such things as species, genera, universals, and the like. Secondly, I shall be leaving out of account such chronologically late productions as Metaphysics VI-X and IV. Thus I shall be concentrating on the Categories, the Topics, the Physics, and the De Generatione et Corruptione. I am not (...) convinced that later works show substantial change over the works which I shall be discussing, but the later works do present severe exegetical difficulties which could not be adequately met within the scope of this essay.

This essay examines the proposal that psychological essentialism results from a history of natural selection acting on human representation and inference systems. It has been argued that the features that distinguish essentialist representational systems are especially well suited for representing natural kinds. If the evolved function of essentialism is to exploit the rich inductive potential of such kinds, then it must be subserved by cognitive mechanisms that carry out at least three distinct functions: identifying these kinds in the (...) environment, constructing essentialized representations of them, and constraining inductive inferences about kinds. Moreover, there are different kinds of kinds, ranging from nonliving substances to biological taxa to within-species kinds such as sex, and the causal processes that render these categories coherent for the purposes of inductive generalization vary. If the evolved function of essentialism is to support inductive generalization under ignorance of true causes, and if kinds of kinds vary in the implicit assumptions that support valid inductive inferences about them, then we expect different, functionally incompatible modes of essentialist thinking for different kinds. In particular, there should be differences in how biological and nonbiological substances, biological taxa, and biological and social role kinds are essentialized. The functional differences between these kinds of essentialism are discussed. (shrink)

Cimpian & Salomon present promising steps towards understanding the cognitive underpinnings of adult essentialism. However, their approach is less convincing regarding ontogenetic and evolutionary aspects. In contrast to C&S's claim, the so-called inherence heuristic, though perhaps vital in adult reasoning, seems an implausible candidate for the developmental and evolutionary foundations of psychological essentialism. A more plausible candidate is kind-based object individuation that already embodies essentialist modes of thinking and that is present in infants and nonhuman primates.

One of the basic intuitions guiding Sartre's phenomenological works is that phenomena cannot be reduced to essences that are separate from appearances. Such a separation leads to a type of semiotic profusion that Sartre criticizes in L'Etre et le néant by evoking the example of Proust. Sartre's ontology must avoid this infinite proliferation of meaning without falling into a type of essentialism where things are merely what they appear to be. Sartre's references to Proust demonstrate not only the pitfalls (...) of essentialism and unlimited semiosis, but also why Sartre found it necessary to invent existential psychoanalysis as a response to the twin phenomenological challenge of situating intentional meaning neither on the side of the object, nor of the subject, but somewhere in between. The unsatisfactory nature of Sartre's solution is palpable in the contradictions we discover in his observations on Proust. (shrink)

The architects of the modern synthesis banned essentialism from evolutionary theory. This rejection of essentialism was motivated by Darwin’s theory of natural selection, and the continuity of evolutionary transformation. Contemporary evolutionary biology witnesses a renaissance of essentialism in three contexts: “origin essentialism” with respect to species and supraspecific taxa, the bar coding of species on the basis of discontinuities of DNA variation between populations, and the search for laws of evolutionary developmental biology. Such “new (...) class='Hi'>essentialism” in contemporary biology must be of a new kind that accommodates relational (extrinsic) properties as historical essences and cluster concepts of natural kinds.

Experimental results in reference to Brazilian children and adults are presented in the context of current discussions about essentialism and folkbiology. Using an adoption paradigm, we replicate the basic findings of a previous article in this journal concerning the early emergence in children of a birth-parent bias. This cognitive bias supports the claim that causal essentialism cross-culturally constrains the reasoning about the origin, development and maintenance of the characteristics and identity of living kinds. We also report some (...) intriguing differences with earlier findings that speak to theoretical and methodological issues of cultural relativity. (shrink)

Over the past several decades, psychological essentialism has been an important topic of study, incorporating research from multiple areas of psychology, philosophy and linguistics. At its most basic level, essentialism is the tendency to represent certain concepts in terms of a deeper, unobservable property that is responsible for category membership. Originally, this concept was used to understand people’s reasoning about natural kind concepts, such as TIGER and WATER, but more recently, researchers have identified the emergence of essentialist-like intuitions (...) in a number of other contexts, including people’s representation of concepts like SCIENTIST or CHRISTIAN. This paper develops an account that aims to capture how essentialism may operate across these varied cases. In short, we argue that while there is diversity in the forms essentialism can take, these varied cases reflect the same underlying cognitive structure. (shrink)

Ernst Mayr has argued that Darwinian theory discredited essentialist modes of thought and replaced them with what he has called "population thinking". In this paper, I characterize essentialism as embodying a certain conception of how variation in nature is to be explained, and show how this conception was undermined by evolutionary theory. The Darwinian doctrine of evolutionary gradualism makes it impossible to say exactly where one species ends and another begins; such line-drawing problems are often taken to be the (...) decisive reason for thinking that essentialism is untenable. However, according to the view of essentialism I suggest, this familiar objection is not fatal to essentialism. It is rather the essentialist's use of what I call the natural state model for explaining variation which clashes with evolutionary theory. This model implemented the essentialist's requirement that properties of populations be defined in terms of properties of member organisms. Requiring such constituent definitions is reductionistic in spirit; additionally, evolutionary theory shows that such definitions are not available, and, moreover, that they are not needed to legitimize population-level concepts. Population thinking involves the thesis that population concepts may be legitimized by showing their connections with each other, even when they are not reducible to concepts applying at lower levels of organization. In the paper, I develop these points by describing Aristotle's ideas on the origins of biological variation; they are a classic formulation of the natural state model. I also describe how the development of statistical ideas in the 19th century involved an abandoning of the natural state model. (shrink)

This paper considers Kripke's (1972, 1980) modal arguments against descriptivism about proper names, the descriptivist reply that the meaning of a name is given by a description involving the modifier ‘actually’, and Kit Fine's (1994) distinction between necessary and essential attributes. It explains how Kripke's modal arguments can be recast in essentialist terms by appealing to Fine's distinction, and it argues that the resulting essentialist arguments are immune to the abovementioned descriptivist reply to the original modal arguments.

The book addresses three main issues. The first concerns the essences (natures, identities) of biological taxa, particularly species. Kripke and other metaphysicians hold that these essences are (at least partly) intrinsic, underlying, probably largely genetic properties. This view, based largely on intuitions, is dismissed by the consensus in the philosophy of biology as being incompatible with Darwinism and reflecting ignorance of biology. The book argues that the demands of biological explanation show that the metaphysicians are right. The positive view of (...) the consensus is that the essences are wholly relational: taxa must have certain histories. The book argues that there is indeed an historical component to the essence, but this component presupposes an intrinsic component. The book’s second issue concerns the essences of biological individuals. Metaphysicians have had much to say about this, again on the basis of intuitions. Many hold that an individual is essentially a member of its species. This has recently been unequivocally rejected by philosophers of biology. The book appeals to biological explanation again to argue for essential membership; furthermore, to argue for the Kripkean view that an organism’s essence is partly intrinsic and partly relational (a matter of origin). Finally, the book addresses the lively contemporary issue of whether race is biologically “real”. From the perspective developed earlier, the book argues that there are indeed racial kinds, in some sense, that are “in the realm of the biological”. These kinds also have partly historical and partly intrinsic underlying essences. (shrink)

Metaphysical realism is the view that most of the objects that populate the world exist independently of our thought and have their natures independently of how, if at all, we conceive of them. It is committed, in my opinion, to a robust form of essentialism. Many modern forms of anti-realism have their roots in a form of conceptualism, according to which all truths about essence knowable by us are ultimately grounded in our concepts, rather than in things 'in themselves'. (...) My aim is to show that conceptualist anti-realism is an incoherent doctrine and how we can support metaphysical realism and robust essentialism, while still properly acknowledging the cognitive role of concepts in mediating our grasp of the nature of mind-independent reality.RésuméLe réalisme métaphysique est la conception suivant laquelle la plupart des objets qui peuplent le monde existent indépendamment de notre pensée et possèdent une nature indépendante de la manière dont nous pouvons éventuellement la concevoir.

The essentialism story is a version of the history of biological classification that was fabricated between 1953 and 1968 by Ernst Mayr, who combined contributions from Arthur Cain and David Hull with his own grudge against Plato. It portrays pre-Darwinian taxonomists as caught in the grip of an ancient philosophy called essentialism, from which they were not released until Charles Darwin's 1859 Origin of Species. Mayr's motive was to promote the Modern Synthesis in opposition to the typology (...) of idealist morphologists; demonizing Plato served this end. Arthur Cain's picture of Linnaeus as a follower of 'Aristotelian' (scholastic) logic was woven into the story, along with David Hull's application of Karl Popper's term, 'essentialism', which Mayr accepted in 1968 as a synonym for what he had called 'typological thinking'. Although Mayr also pointed out the importance of empiricism in the history of taxonomy, the essentialism story still dominates the secondary literature. The history of the first telling of the essentialism story exposes its scant basis in fact. (shrink)

In his famous essentialist account of identity, Kripke holds that it is necessary to the identity of individual people that they have the parents they do in fact have. Some have disputed this requirement, treating it either as a reason to reject essentialism or as something that should be eliminated in order to make essentialism stronger. I examine the reasoning behind some of these claims and argue that it fails to acknowledge the complex and multi-faceted importance of biological (...) process in determining identity and distinguishing significant differences between biological and non-biological cases. In fact, this failure derives from an inherent tendency to treat the biological case in just the same way as the non-biological case at least at one important point in its history—the point of formation. This analysis offers a way of salvaging Kripke’s original claims. I focus in particular on the views of Graeme Forbes and Teresa Robertson, but also discuss the views of Nathan Salmon, M. S. Price and E. J. Lowe. (shrink)

THE DISTINCTION BETWEEN ESSENCE AND EXISTENCE has been taken to be central to Avicenna’s metaphysics and ontology of being. Due to the influence that this distinction had on Thomism, and to a lesser extent on Maimonides’s work, some Medievalists and Orientalists took Avicenna’s distinction between essence and existence to be characterized by essentialism. A.-M. Goichon’s books Léxique de la Langue Philosophique d’Ibn Sina, Vocabulaires Comparés d’Aristote et d’Ibn Sina, and La Philosophie d’Avicenne et son Influence en Europe all offer (...) a great contribution to the translation and understanding of Avicenna’s works. However the interpretive reception of Goichon’s works has had a strong influence on subsequent Medievalists as well as Orientalist scholars. This impact on scholars, along with the stress on Avicenna’s influence on Thomism, has led in some instances to an exaggerated stress on the centrality of the essence/ existence distinction in Avicenna’s metaphysics. This state of affairs has eventually overshadowed other important aspects of Avicenna’s ontology of being and of his metaphysical and logical analysis of being in terms of the modalities of necessity, contingency, and impossibility. The examination of Avicenna’s metaphysics under the spell of all of these factors leads to an intellectually discomforting position that construes his ontology as essentialism. Consequently this leads to the interpretation of his work as being that of a metaphysician who subordinates existence to essence. Such interpretation has been even adopted by experts on Avicenna’s work within the Western scholarship as well as among some Arabists. For instance, some scholars stress that Averroes and Mulla Sadra are the metaphysicians of existence, while taking Avicenna to be the metaphysician of essence. John Caputo, a leading interpreter of Heidegger’s thought, makes extensive references to the work of the Thomist scholar Étienne Gilson in the context of examining Aquinas’s adoption of the Avicennian distinction between essence and existence. Caputo’s discussion of the essence/existence distinction adopts the standpoint that Gilson reflects in the reading of Avicenna’s metaphysics as being the starting point of a longstanding essentialist tradition that culminates with Hegel’s Science of Logic. This line of argumentation already supplies Caputo with sufficient arguments that enable him readily to stamp Avicenna’s metaphysics with Heidegger’s critique of the metaphysical tradition. Caputo based himself on what the Thomist scholar Gilson offers in this regard, particularly in taking Aquinas’s metaphysics to be the metaphysics of esse. Gilson’s position may itself be questioned on the ground that its interpretation of Avicenna has been pervaded by Thomist inclinations; this is the case, given that Gilson and other scholars construe Avicenna’s metaphysics as being essentially the metaphysics of essence. Based on this, Caputo accepts the claim that Avicenna’s ontology is essentialist. Such readings lead to the conclusion that Avicenna subordinates existence to essence and consequently that his ontology is characterized by what Heidegger takes to be a mark of the oblivion of being. The question that ought to be raised in this regard is whether the position of secondary scholarly sources is accurate. This is the case, given that some of the scholars, who propagate the claim that Avicenna is an essentialist, are after all scholars who have not consulted or studied the primary sources. Rather, they primarily rely on secondary sources that mediate Avicenna’s metaphysics through the Thomist scholarship and Latin translations. This is clearly the case with Gilson’s consideration of Avicenna’s corpus, which is addressed from the standpoint of Latin renderings of Avicenna’s texts rather than consulting the original Arabic or Persian texts. Having said that, the issue becomes more complicated in the light of considering Arabist or Medievalist scholars who do consult the primary Arabic sources, yet still hold that Avicenna is an essentialist. Such scholars remain under the influence of earlier translations and interpretations that were offered by prominent Orientalist scholars, who addressed the essence/ existence distinction in the light of broad philosophical concerns with Medieval Latin and Jewish philosophy, or by tracing the Aristotelian and Peripatetic influences on Islamic and Arabic philosophy. Some scholars like Gilson might even go further in terms of considering the works of Avicenna and Averroes from the standpoint of mapping out the doctrinal quarrels between Scotism and Thomism. The Medievalists who consult primary sources, yet who are still under the spell of earlier Orientalist views, do not attempt to review some of their positions by going back to a closer examination of the texts and to a questioning reception of dominant translations and interpretations. There is a hermeneutic need to return to the primary texts and to reexamine them in the light of new philosophical concerns. This return and reexamination are also needed in the light of questioning and adopting new methodological inclinations in translation and interpretation. This becomes a pressing issue given the seriousness of the philosophical consequences that might arise if we readily take Avicenna’s metaphysics to be characterized by essentialism. The examination of Avicenna’s ontology must account for the renderings of the terms mahiya, dhat, and wujud, be it in Latin, English, or French, or in terms of the Arabic/persian semantic, syntactic, and grammatical structure and derivation. The nuances of translation are determined by how these terms are philosophically used within the text and in the course of the development of Avicenna’s arguments. Such linguistic investigations would elucidate the philosophical interpretation of the essence/existence distinction in the light of addressing contemporary philosophical concerns, as these are attested with the consideration of Heidegger’s critique of classical ontology.

In this commentary paper, we are taking one step further in questioning the central assumptions in the bioethical debates about reproductive technologies. We argue that the very distinction between “person affecting” and “identity affecting” interventions is based on a questionable form of material-origin essentialism.

It would also challenge the (...) idea that normative reasons we have in these two types of cases markedly differ in strength. (shrink)

Aristotle's modal syllogistic has been an object of study ever since the time of Theophrastus; but these studies have been somewhat desultory. Remarkably, in the 1990s several new lines of research have appeared, with series of original publications by Fred Johnson, Richard Patterson and Ulrich Nortmann. Johnson presented for the first time a formal semantics adequate to a de re reading of the apodeictic syllogistic; this was based on a simple intuition linking the modal syllogistic to Aristotelian metaphysics. Nortmann developed (...) an ingenious de dicto analysis. Patterson articulated the links between the modal syllogistic and the metaphysics, using an analysis which strictly speaking is neither de re nor de dicto. My own studies in this field date from 1976, when my colleague Peter Roeper and I jointly wrote a paper "Aristotle's apodeictic syllogisms" for the XXIInd History of Logic Conference in Krakow. This paper contained the disjunctive reading of particular affirmative apodeictic propositions, which I still favour. Nonetheless, I did not consider that paper's results decisive or comprehensive enough to publish, and my 1981 book The Syllogism contained no treatment of the modal syllogism. The paper's ideas lay dormant till 1989, when I read Johnson's and Patterson's initial articles. I began publishing on the topic in 1991. Gradually my thoughts acquired a certain comprehensiveness and systematicity, till in 1993 I was able to take a semester's sabbatical to write up a draft of this book. (shrink)

In a recent contribution, Ereshefsky (2007a) maintained the following points against Nixon and Carpenter (2000), Keller et al. (2003), and Rieppel (2005a, 2006a,b): (1) that species and taxa are individuals, not natural kinds; (2) that “origin essentialism” conflates qualitative essentialism with genealogical connectedness; and (3) that rigid designation theory applies to taxon names. Here I argue that: (1) the conception of species as individuals or natural kinds is not mutually exclusive but rather context sensitive; species are best (...) seen as spatio-temporally located processual systems that instantiate an HPC natural kind; (2) “origin essentialism” is problematic because of the fuzzy boundaries of species and taxa, yet required if rigid designation theory is to apply to taxon names; and (3) the theories of direct reference and rigid designation do not apply to taxon names.

In 2002, Evolution and Human Behavior published a study purporting to show that the differences in toy preferences commonly attributed to girls and boys can also be found in male and female vervet monkeys, tracing the origin of these differing preferences back to a common ancestor. Despite some flaws in its design and the prima facie implausibility of some of its central claims, this research received considerable attention in both scientific circles and the popular media. In what follows, I (...) survey some of the problems with this study that seem to be characteristic of research into sex differences in a particular research program in evolutionary psychology. I suggest that an epistemology of ignorance is at work that suppresses the methods and insights of an earlier research program, which emphasized the complexity and contingency that ultimately grounds the variety of human behaviors, in favor of one that has been widely criticized as empirically flawed and politically pernicious. I conclude with some speculative remarks on the persistence of this problematic research program in evolutionary psychology. (shrink)

Scholars agree that Aristotle held a view that has been called "Aristotelian Essentialism" , but disagree about what this thesis entails. I reconstruct as the view that there are certain individuals, namely substances, that have essences, and that essences are to be understood as "explanatorily basic" features of an individual--features of an individual substance that serve as part of a scientific explanation of the presence of other features of that individual, but are not themselves explained in this way. When (...) Aristotle's view is understood in this way, interesting differences and parallels between him and contemporary essentialists emerge. For one, so-called "properties of origin" such as "being born to George and Barbara Bush" are not essential to the individual that has them, on Aristotle's view. Furthermore, understanding Aristotle's view in this way explains why essences are not, as it has often been maintained, merely "career attributes"--properties that an individual has necessarily and at each moment at which it exists. I argue that for Aristotle, essences belong to an individual in virtue of the species to which it belongs, and that Aristotle subscribes to the "species-form" view of essence. I examine and respond to arguments to the contrary that, in both the Metaphysics and the Generation of Animals, Aristotle holds that the essence of an individual substance is an "individual form" unique to that thing, and not shared by any other individual. Aristotle's account of family resemblances, in particular, has been thought by many to present problems for understanding Aristotle's essentialism. In that text it looks like Aristotle gives up on the view that only certain features--the ones that define the species--are essential to an individual when he attempts to explain the phenomena of family resemblance. I conclude with a sketch of a reading of this text that shows Aristotle holding an account of family resemblances that is consistent with the view that only certain features--the explanatorily basic ones--are part of the essences of individual substances.

Author’s Introduction Intuitively, George Clooney could lose a finger and he would still be him. Also intuitively, he could not lose his humanity without ceasing to be altogether. So while he could have one less finger, he could not be other than human. These intuitions suggest (...) that there are two kinds of properties: on the one hand, there are essential properties and, on the other, there are accidental properties. Essentialism is the view that captures those intuitions and claims that some of an object’s properties are essential and some are accidental. Essential properties are often appealed to in metaphysical arguments. Consider the famous Goliath–Lumpl example. Goliath is a clay‐statue, and Lumpl is the piece of clay from which Goliath is made. Are Goliath and Lumpl the same entity, or are they distinct, despite coinciding in the same spatial region (at least for a period of time)? An argument in favour of their distinctness appeals to essential properties. Let s be Goliath’s shape. Lumpl’s current shape is therefore also s. It seems that Lumpl could lose its current shape and still exist. Yet, if Goliath – the statue – were melted, for instance, it would cease to exist. Behind this reasoning is the belief that having shape s is essential to Goliath but not to Lumpl. Goliath and Lumpl can therefore be distinguished by their essential properties. Consequently, and by Leibniz’s Indiscernibility of Identicals– according to which identicals cannot be distinguished – Goliath and Lumpl are distinct objects. The essentialist intuition appealed to in this argument is that shapes are essential to statues but not to pieces of clay. Of course, this particular argument – like any other – can be resisted. It is all the same a good illustration of how essentialism is put to work in metaphysics. A good understanding of the broad phenomenon of essentialism is therefore an unavoidable task, since the credit of a lot of metaphysical arguments partially depends on it. Although the topic has been studied for millenniums, the two papers that this guide accompanies are focused on contemporary issues in essentialism, and so will do this guide too. Author Recommends Fine, Kit. ‘Essence and Modality.’Philosophical Perspectives 8 (1994): 1–16. One of the most cited and influential papers against the modal account of the notion of essence and in favour of what has subsequently been referred to in the literature as ‘the Finean account of the notion of essence’. Forbes, Graeme. The Metaphysics of Modality. Oxford: Clarendon Press, 1985. A foundational work in modality and essentialism. The first two chapters provide a valuable introduction to propositional and first order modal logic. Chapters 5–8 constitute a comprehensive essentialist theory and contain some of the most cited arguments for individual essences. Kripke, Saul. Naming and Necessity, Cambridge, MA: Harvard UP, 1972/1980. Another foundational work. With this book – which is, among other things, a defence of a Direct Theory of Reference – Kripke rescues, after Quine’s powerful attacks against it, and using the semantic rigidity of proper names, (Aristotelian) essentialism. Mackie, Penelope. How Things Might Have Been: Individuals, Kinds and Essential Properties. Oxford: Clarendon Press, 2006. An extremely valuable recent contribution to the field. Here, Mackie defends that, although essentialism is a real phenomenon, there are much fewer essential properties than is standardly believed, and labels this view ‘Minimalist Essentialism’. Beyond the intrinsic interest of the defence of Minimalist Essentialism, the book is also highly recommended for its clear reconstructions – and discussions – of some of the most influential essentialist arguments. In addition, the book’s bibliography is very comprehensive and updated, and it might be a useful resource for students. Plantinga, Alvin. The Nature of Necessity. Oxford: OUP, 1974. Yet another foundational work. Here, Plantinga offers his essentialist theory which, like Forbes’, also incorporates individual essences although of a very different sort from Forbes’. Plantinga believes in purely non‐qualitative individual essences, whereas Forbes’ aims at purely qualitative ones. The book is also excellent to provide a solid background to those unfamiliar with the topic. Roca‐Royes. ‘Essentialism vis‐à‐vis Possibilia, Modal Logic and Necessitism.’Philosophy Compass, 6/1 (2011): 54–64, doi: 10.1111/j.1747‐9991.2010.00363.x. This is one of the two papers this guide accompanies. It contains a comparative examination of two opposed responses to the problem of possibilia. One solution crucially appeals to individual essences and another – compatible with them, but not dependent on them – makes existence a necessary‐whenever‐possible property. Salmon, Nathan. Reference and Essence. Princeton: Princeton UP, 1981. Against what Kripke’s Naming and Necessity might have induced us to believe, Salmon’s Reference and Essence argues that essentialism cannot be derived from the Direct Theory of Reference. Our commitments to essentialism should therefore come from somewhere else. It also contains one of the most cited and influential arguments against the transitivity of the accessibility relation between worlds, which relies on flexible essential properties. Online Materials The Stanford Encyclopedia of Philosophy publishes extremely valuable entries on a vast variety of topics which are conveniently updated and revised. On essentialism, the following are to be highlighted: Teresa Robertson, ‘Essential vs. Accidental Properties’: Takashi Yagisawa, ‘Possible Objects’: Penelope Mackie, ‘Transworld Identity’: PhilPapers is an interactive directory of online philosophical publications to which one can subscribe, and which allows authors to submit their latest work. One might find it useful to check this on a regular basis, since contents are constantly updated. The following link is to the site’s resources on essentialism:. Sample Syllabus Because the phenomenon of essentialism is very broad, one can design an entire course on it, thereby having enough time to see some of the issues in considerable depth. The sample syllabus suggested here is of one such course, focusing exclusively on contemporary issues in essentialism. Less deeply, the topic of essentialism can also be introduced in a general course on metaphysics or on modality. To this effect, focusing on some of the topics suggested in weeks 1–6 below would perhaps be more appropriate than focusing on the more complex issues suggested for weeks 7–10. Week 1.

Focus Questions • There is a debate as to whether essential properties– as well as individual essences and sufficient‐for‐existence properties– should be specified in purely qualitative terms or whether, by contrast, non‐purely qualitative – or even purely non‐qualitative – specifications are allowed. What are the main arguments against the availability of purely qualitative specifications? • Flexible essential properties seem to be more plausible than non‐flexible ones. Yet, together with sufficient‐for‐existence properties, they imply flexible individual essences. How plausible are these? Should we revise our intuitions supporting flexible essential properties? • What are, ultimately, the ontological differences between a necessitist approach to possibilia and an individual‐essences‐based approach? • According to necessitism, essential properties do not impose necessary conditions for an object’s existence. Can the necessitist, nonetheless, capture this role of essential properties by saying that, when it comes to possibly concrete entities, essential properties provide necessary conditions for an object’s concreteness? Can they, on a similar vein, also offer sufficient‐for‐concreteness properties as a surrogate for the (non‐necessitist’s) sufficient‐for‐existence properties? • Even after the enormous amount of literature that essentialism has generated, we are far from reaching a general agreement as to which properties are essential and which are accidental. Should this be a reason to reflect, critically, on the methodology that is being used in the arguments for or against essential properties? Is reliance on intuitions inescapable? (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Plato's Essentialism: Reinterpreting the Theory of Forms by Vasilis PolitisTravis ButlerPOLITIS, Vasilis. Plato's Essentialism: Reinterpreting the Theory of Forms. New York: Cambridge University Press, 2021. x + 251 pp. Cloth, $99.99The reinterpretation of the theory of forms to which Politis refers in this book's subtitle is accomplished by foregrounding the conception of forms as essences—the kinds of beings we must countenance if we pose, pursue, and (...) believe we can answer the "What is F?" question. Politis argues that some of Plato's arguments for introducing forms have been distorted by the assumption that he is primarily interested in the Aristotelian question about substance or a Parmenidean quest for stable objects of thought and knowledge. By focusing on forms as the targets of the "What is F?" [End Page 154] question, we can dispel these misconceptions and bring the Platonic theory more clearly into view.Chapter 1 includes the cornerstone of Politis' interpretation—an original reading of a brief passage in the Hippias Major. Hippias is an important interlocutor for the project because he holds that the "What is F?" question can be answered by asking instead, "Which things exemplify F?" Let's call the claim that "What is F?" can be answered by examples "The Exemplar Doctrine" (ED). Politis argues that Hippias' commitment to ED leads him to deny the existence of a single exemplar for all cases—a denial he is forced subsequently to rescind. Thus, by endorsing the search for exemplars over the search for essence, Hippias sows the seeds of his own refutation.Readers might wonder how an account of a brief passage in the Hippias Major, apparently innocent of transcendent metaphysics, could serve as the cornerstone of a reinterpretation of the theory of forms. The initial answer in chapter 2 is that the rejection of ED is taken to imply that forms are imperceptible. The implication follows because Politis takes the supposition that F is definable by example to be biconditionally related to the claim that the essence of F is perceivable by the senses. When Socrates gets Hippias to reject ED, then, he gets him (tacitly) to accept that the essence of F is not perceivable by the senses. A central tenet of Platonism, the imperceptibility of forms, thus follows from an initial point about the proper way to answer the "What is F?" question.Chapter 3 continues in a similar vein, arguing that many special features attributed to forms in the Phaedo and Republic, such as their unity, uniformity, and incompositeness, follow from facts about inquiry into essences. Politis argues that these features belong, in the first instance, to defining accounts of forms and only secondarily to the forms themselves. Skeptical readers might observe that the focus in the Phaedo is much more on the forms than on defining accounts of them. In addition, it should be noted that the list of special features on which Politis focuses is somewhat selective. Chapters 2 and 3 include no discussion of the divinity and purity of forms or their status as alone by themselves. The divinity of forms is crucial for their role in Plato's ethics, but it seems unlikely to be explained by anything related to the "What is F?" question.In chapter 4, Politis defends a novel account of the epistemology of the Phaedo. He argues that it should be viewed through the lens of the account of inquiry in that dialogue, though not the central notion of inquiring with the soul by itself. Instead, we should focus on the passage in which Socrates claims that sense perception of deficiently equal sticks puts us in mind (ennoēsai) of the equal itself (74c–75b). Politis takes this claim to imply that sense perception plays a justificatory and not merely causal role in acquiring knowledge, though the textual arguments of this chapter fall short of establishing that striking claim.Chapter 5 takes on arguments in the Phaedo and Republic that appear to distinguish forms from sensibles on the grounds that the latter but not the former suffer the compresence of opposites (for example, appearing [End Page 155] both equal and unequal). Politis argues that scholars... (shrink)

This is a three paper dissertation. ;for paper 1. Quine held that quantifying into modal contexts is illegitimate. It is sometimes thought that if he is right about this, then essentialist claims make no sense. Perhaps as a consequence of this thought together with the current prominence of essentialist views, there have been two good fairly recent attacks on Quine's argument against quantifying into modal contexts: Neale's revival of Smullyan's points and Kaplan's paper "Opacity". I first argue that Quine's view (...) is not refuted by Neale or Kaplan. I next explain that nonetheless, essentialists need not surrender in the face of Quine's injunction against quantifying in. Quine's work does not rule out the intelligibility of essentialist theses; it does however issue a challenge to explain the mysterious notion of metaphysical necessity. ;Abstract for paper 2. I examine the case that has been made for origin essentialism and find it wanting. I focus on the arguments of Salmon and Forbes. Like most origin essentialists, they have been concerned to respect the intuition that slight variation in the origin of an artifact or organism is possible. But, I argue, both of their arguments fail to respect this intuition. Salmon's argument depends on a sufficiency principle for crossworld identity, which should be rejected, if---as Salmon concedes---a given artifact might have been originally made from slightly different material. Similarly, Forbes's argument succeeds only if essentially the same argument can be used to establish a claim that---by his own admission---is too strong, namely that no variation, however slight, in an organism's origin is possible. ;Abstract for paper 3. Chisholm's Paradox suggests that origin essentialism is incompatible with the view that some variation in the origin of a given thing is possible. Since the latter view is strongly supported by intuition, origin essentialists have been eager to offer solutions to the paradox. In this paper I look at three allegedly different solutions to the paradox: Forbes's, Salmon's, and Lewis's. I give new criticisms of Forbes's view and offer new defenses of what I call the "Salmon-Lewis solution". (shrink)

This is the first book-length study of Descartes's metaphysics to place it in its immediate historical context, the Late Scholastic philosophy of thinkers such as Suárez against which Descartes reacted. Jorge Secada views Cartesian philosophy as an 'essentialist' reply to the 'existentialism' of the School, and his discussion includes careful analyses and original interpretations of such central Cartesian themes as the role of scepticism, intentionality and the doctrine of the material falsity of ideas, universals and the relation between sense and (...) understanding, causation and the proofs of the existence of God, the theory of substance, and the dualism of mind and matter. His study offers a picture of Descartes's metaphysics that is both novel and philosophically illuminating. (shrink)

In modern philosophy, essentialism is in most cases regarded as an outdated and, in fact, incorrect philosophical trend. And one of the scientists who created such a reputation of essentialism was the famous English philosopher of Austrian origin Karl Popper. The success of his book “The Open Society and its Enemies” led to the fact that in the West essentialism began to be considered not only cognitively untenable, but also suspicious as the theoretical basis of fascism, (...) communism and totalitarianism. In the article, K. Popper’s arguments against essentialism are reviewed all over again, and it is shown that K. Popper’s criticism of essentialism as an anti-scientific and outdated doctrine is not the point of view of the philosophy as a whole, but it is just the position of empirical positivism. Essentialism deals with the reality that lies on the other side of phenomena. And this, according to K. Popper, necessarily leads to “ultimate” definitions. However, in accordance with the doctrine of falsification by K. Popper himself, every scientific conclusion within its expiration date is “ultimate”. The article shows that in reality essentialism did not only play an extraordinary role in the classical metaphysical theory of knowledge, but also continues to do so within the framework of modern ontology. Moreover, in the latter case, he does it with the help of abduction which is a specific form of logical inference generating scientific hypotheses. The existence of abduction in science, which generates new knowledge, suggests that essentialism is not something, at best, tolerable and excusable. This is the main way to development of sciences in general. In all cases, the author of the article considers only logical entities, but not legal, theological or any other. (shrink)

This book intervenes in the field of intersectionality studies: the integrative examination of the effects of racial, gendered, and class power on people’s lives. While “intersectionality” circulates as a buzzword, Anna Carastathis joins other critical voices to urge a more careful reading. Challenging the narratives of arrival that surround it, Carastathis argues that intersectionality is a horizon, illuminating ways of thinking that have yet to be realized; consequently, calls to “go beyond” intersectionality are premature. A provisional interpretation of intersectionality can (...) disorient habits of essentialism, categorial purity, and prototypicality and overcome dynamics of segregation and subordination in political movements. -/- Through a close reading of critical race theorist Kimberlé Williams Crenshaw’s germinal texts, published more than twenty-five years ago, Carastathis urges analytic clarity, contextual rigor, and a politicized, historicized understanding of this widely traveling concept. Intersectionality’s roots in social justice movements and critical intellectual projects—specifically Black feminism—must be retraced and synthesized with a decolonial analysis so its radical potential to actualize coalitions can be enacted.

There is a broad consensus in the literature that in the section on ‘The Genus’ in theScience of Logic, Hegel argues that any living being must exist among other instances of its kind, with which it reproduces to create future generations, and out of which it was itself produced. This view is not only hard to motivate philosophically, it also seems to contradict many things Hegel says elsewhere in his system about the details of living nature, especially concerning the reality (...) of spontaneous generation. After an examination of the secondary literature on ‘The Genus’, I offer an alternative view of this section, which I call ‘the Modal Reading’. The Modal Reading sees the language of pluralities in ‘The Genus’ as really Hegel's peculiar way of articulating certain modal features of thoughts about the living: to grasp a living individual as living, we need to distinguish not only between this individual and its environment, but also between the things this individual actually does and other possibilities which it does not actualize. The Modal Reading has a logical motivation insofar as it articulates what is needed to think of a living being as living, but it also avoids saddling Hegel with the problematic entailments he is usually read as taking on in this section. A further upshot of the Modal Reading is that approaching Hegel in this way provides us with a way to see Hegel as defending a non-nominalistic alternative to essentialist accounts of living kinds. Finding a way to read ‘The Genus’ which coheres with Hegel's views elsewhere in his system thus shows Hegel to have been an especially subtle and penetrating thinker, with continuing relevance for the philosophy of biology.

Fortunately, the challenge of alienation is now again taken seriously in intellectual discussions. Already years ago, Axel Honneth made the reflection on alienation a defining issue for social philosophy per se, and as the prime example of social philosophy, he brought forth Critical Theory. Within this horizon, recently two conceptions of alienation have been proposedby Rahel Jeaggi and Hartmut Rosa, and the present article takes issue with both of these proposals, criticizing in particular their anti-essentialism. Hence, questioning the post-metaphysical (...) agenda that Jaeggi has inherited from Honneth, I criticize her juxtaposition of the existentialist and the Marxist critique of alienation, her understanding of the good life as autonomy, and finally her acceptance of post-modern and liberal criticism of metaphysics and ontology. Turning to Rosa, I appreciate his societal approach to the critique of alienation, emphasizing the significance of capitalist modernity, but also he accepts the post-metaphysical agenda, and his aesthetic idea of the good life as resonance remains strongly individualistic. Both of these conceptions of alienation thus have ideological implications that threatens to turn upside down the original intentions and implications of Critical Theory in relation to social and political justice. To conclude, the criticism of capitalism, political economy and real life politics is still relevant for understanding alienation, and therefore it is worth returning to the classics of the discussion.

Available from UMI in association with The British Library. Requires signed TDF. ;The main part of the thesis concerns how things, in the sense of individuals, might have been. The topic is what limits there are on the counterfactual possibilities for individuals: in other words, what essential properties, if any, they have. ;In Chapters 3-6 three answers to this question that have been given in recent philosophical literature are examined. They are: that each thing has a unique individual essence ; (...) that there are features of the origin of an individual without which it could not possibly have existed ; and, finally, that there are sortal concepts that represent essential properties of the things that fall under them . ;All of these answers, and many of the arguments that have been given for them, are criticised. Sometimes the criticism takes the form of pointing to unpalatable consequences that result from the acceptance of the doctrine in question. Sometimes the criticism consists in pointing to difficulties or inadequacies in the arguments that have been presented in its favour. ;A preliminary chapter prepares the ground by setting out the conceptual framework, and the chief formal characteristics, of the essentialism discussed in the later chapters. Chapter 2 discusses the nature of necessary a posteriori truth, touching on questions in the philosophy of language and mind concerning the notion of de re thought. ;It is argued that essentialism about natural kinds raises problems of its own: some of these are discussed in Chapters 7 and 8. Here the main topic is the connection between semantic theory and natural kind essentialism. Concluding that the essentialism should be regarded as in an important sense independent of semantic theory, the chapters add to, and also criticise, the work of other writers who have reached the same verdict. Scepticism is also expressed about the independent plausibility of natural kind essentialism. ;Recent interest in essentialism owes its genesis chiefly to the work of Saul Kripke and Hilary Putnam: these figures stand in the background throughout the discussion. Among the other writers whose work is discussed are Baruch Brody, Gareth Evans, Graeme Forbes, Colin McGinn, J. L. Mackie, D. H. Mellor, Nathan Salmon, and David Wiggins. (shrink)

Natural Kind Essentialism is the view that the objects of sciences like physics, chemistry and biology fall into natural kinds, and that such kinds have essences—sets of properties possession of which is necessary and sufficient for kind-membership. Since Putnam and Kripke brought NKE back onto the philosophical agenda, it has found many advocates. But comparatively little attention has been paid to the question of how this view can be positively motivated. After illustrating the current need for an argument for (...) NKE through critical discussions of Putnam’s, Kripke’s and Ellis’s arguments for NKE, this article aims to show that Hegel offers the resources for an original argument for the view. This argument works by deriving metaphysical implications from an account of what it means to understand an explanandum. (shrink)

THERE are two conflicting motives in Husserlian phenomenology, one of which leads, in my view, to a more genuinely transcendental philosophy. According to one of its original programs, phenomenology was to be a descriptive science of essences and essential structures of various regions of phenomena and also of the empty region of object in general. The concern with meanings, as contradistinguished from essences, is equally original; it pervades the Prolegomena and the first three of the logical investigations and, of course, (...) the first volume of the Ideas. But the specifically phenomenological enterprise of clarification of meanings—and this is the second of the two motives-slowly moves to the forefront, for a while overshadowed by the essentialism of the beginning, but later on freed from it and reasserting its primacy as the philosophical activity par excellence. The concern with essences affiliates phenomenology to the classical rationalistic tradition, while the concern with meanings brings it closer to the empiricistic tradition. If in the former enterprise phenomenology appears to be an essentialism of Aristotelian sort, in the latter, Hume remains its acknowledged precursor. One of my contentions, which I will try to substantiate in the following pages, is that the peculiarly Husserlian sort of transcendental phenomenology develops out of the second concern rather than from the first. This rather broad claim needs to be qualified in various ways, which I will be doing as we proceed. For the present, I may perhaps add this much: there is a conception of transcendental subjectivity which can be reached only through an eidetic phenomenology of essences: on such a theory, transcendental subjectivity is the essence of empirical consciousness, transcendental ego is the essence of the empirical ego. But this is not exactly Husserl’s conception of ‘transcendental'. The transcendental according to Husserl is not the essence of the empirical, but the domain in which the meanings constituting the empirical have their origin. However, I should add that these two points of view are intertwined, in Husserl’s thought, in such a strange manner that my efforts to separate them may seem futile. They influence each other: there are, as a matter of fact, two conceptions of essence in Husserl, one of which is, in my view, closer than the other one to the specifically Husserlian conception of transcendental subjectivity. So also in the theory of meaning, the early essentialism did cast its shadow, but as soon as it is freed from essentialism it lays the foundation of a more truly phenomenological transcendental philosophy.

The longstanding species problem in biology has a history that suggests a solution, and that history is not the received history found in many texts written by biologists or philosophers. The notion of species as the division into subordinate groups of any generic predicate was the staple of logic from Aristotle through the middle ages until quite recently. However, the biological species concept during the same period was at first subtly and then overtly different. Unlike the logic sense, which relied (...) on definitions of the essence of both genus and species, biological species from the time of Epicurus were consistently considered to involve a reproductive element: in short, living species relied not on essential definitions, but on the generative cause, which might not be definable. I term this the generative conception of species: species were the generation by reproduction of form. This undercuts the claim that species before Darwin were essentialist, and divorces the notion of a type from that of essence. In fact, as late as the end of the nineteenth century, logicians explicitly treated biological “species” as a homonym only of logical essentialist species, and permitted considerable deviation from the type or form. At every point, species in logic were thought to be a subset, in effect, of some more general notion. I sketch a history of both philosophical and biological traditions of the species concept, before turning to the current conceptions. These are reconsidered in the light of this history, and in particular Mayr’s changing views are shown to be somewhat Whiggish, historiographically. Of the many touted biological species concepts, only one of which (Mayr’s) is called _the_ Biological Species Concept, none appears to capture all the relevant facts, intuitions, and operational requirements of biology. Cladistic conceptions, however, have much in common with the older philosophical literature, in that the natural group of cladism is the clade, or monophyletic group. After considering the Individuality Thesis, and the metaphysics of species, we see that species are the most particular terminal taxa in a clade, and that they are “defined” in terms of the particular synapomorphies, or evolved characters, that are causally responsible for keeping the lineages that organisms form distinct from one another. In this way, we can remain within the generative conception of species that has been in play for over two millennia, and yet avoid the pitfalls of prior attempts to find a universal conception of species.

In several publications Graeme Forbes has developed and defended one of the strongest arguments for essentialism about biological origins. I attempt to show that there are deep, as yet unrecognized, problems with this argument. The problems with Forbes’s argument suggest that a range of other arguments for various forms of origin essentialism are also likely to be flawed, and that we should abandon the seemingly plausible general metaphysical thesis that concrete entities that share all intrinsic properties are (...) identical.

In this article I contrast two opposing forms of essentialism, definitional and transcendental versus productivist and historical, and trace both forms back to Kripke's Naming and Necessity (1980). Definitional essentialism, as developed by Fine, centers on kind-membership. Historical essentialism, as anticipated by Prior and developed by Almog, puts origin at its center. The article focuses on the fundamentally distinct manners in which these two views handle the necessity of origin thesis. In the final section of (...) the article, inspired by a Nietzschean genealogical methodology, I pursue a naturalization strategy and conclude that rather than origin being necessary, it is essentialist necessity that reduces to origin.
