It is a widely held principle that no one is able to do something that would require the past to have been different from how it actually is. This principle of the fixity of the past has been presented in numerous ways, playing a crucial role in arguments for logical and theological fatalism, and for the incompatibility of causal determinism and the ability to do otherwise. I will argue that, assuming bivalence, this principle is in conflict with standard views (...) about knowledge and the semantics for ‘actually’. I also consider many possible responses to the argument. (shrink)

A style of argument that calls into question our freedom (in the sense that involves freedom to do otherwise) has been around for millennia; it can be traced back to Origen. The argument-form makes use of the crucial idea that the past is over-and-done-with and thus fixed; we cannot now do anything about the distant past (or, for that matter, the recent past)—it is now too late. Peter van Inwagen has presented this argument (what he calls the Consequence Argument) in (...) perhaps its clearest and most forceful way, but debate over the argument has arguably reached a stalemate. -/- Recently, however, Wes Holliday has attempted to break this seeming stalemate by presenting a new argument for the Principle of the Fixity of the Past. Holliday’s argument is subtle and ingenious, and worthy of serious consideration, especially given the promise it holds for genuinely advancing this old debate. In what follows, however, we argue that despite its considerable ingenuity, Holliday’s argument fails to convince, and the stalemate appears to remain. (shrink)

This paper explains the metaphysical implications of the view that species are individuals (SAI). I first clarify SAI in light of the separate distinctions between individuals and classes, particulars and universals, and abstract and concrete things. I then show why the standard arguments given in defense of SAI are not compelling. Nonetheless, the ontological status of species is linked to the traditional "species problem," in that certain species concepts do entail that species are individuals. I (...) develop the idea that species names are rigid designators and show how this provides additional motivation for SAI. (shrink)

Species concepts aim to define the species category. Many of these rely on defining species in terms of natural lineages and groupings. A dominant gene-centred metaconception has shaped notions of what constitutes both a natural lineage and a natural grouping. I suggest that relying on this metaconception provides an incomplete understanding of what constitute natural lineages and groupings. If we take seriously the role of epigenetic, behavioural, cultural, and ecological inheritance systems, rather than exclusively genetic inheritance, a (...) broader notion of what constitutes a natural grouping or lineage may be required. I conclude by outlining an alternative metaconception that is a de-centred metaschema for species. (shrink)

Species is one of the most basic concepts for almost all branches of biology, and it is also one of the most controversial concepts. An important aspect of "the species problem" is the question of "what the ontological status of species is". Traditionally, the answer to the issue about "the ontological status of species" is biological essentialism. Biological essentialism claims that species is a "natural kind", which argues that all and only the members of a (...) species have a common essence. Each species is separated from all others by a sharp discontinuity. However, Darwin's evolutionary theory argues that species are gradual, and the boundaries between species are vague. This view conflicts with biological essentialism. With the continuous transmission of Darwin's theories, biological essentialism was gradually abandoned by philosophers and scientists. In recent years, some philosophers try to resurrect biological essentialism by using new biological resources. Their theories are known as New Biological Essentialism, which mainly includes three different approaches: The Barcode Theory of DNA, Relational Essentialism, and HPC Theory. However, there are so many defects in their theories that they don't provide a successful defense for biological essentialism. By analyzing these theories, I try to point out that the dilemma and failure of new biological essentialism dues to the conflict between its ontological presupposition and modern biological practice. The conflict leads to the tension between essentialism and biology. Further, I argue that the best way to eliminate the tension between biology and essentialism is to regard species as “heterogeneous kinds”. This new understanding of species abandons biological essentialism at the ontological level but retains the value of epistemology of regarding the species as “natural kinds”. (shrink)

Heated debates stemming from the confrontation of scientific knowledge with the biblical picture of the creation of man, which had followed the publication of Darwin's theory of evolution, became far less prominent in the second half of the 20th century. This was due to two factors: first, the theory of evolution was partly accepted in theological circles and at the same time biologists showed a growing awareness of the limited epistemological scope of the competence of the natural sciences. This lesson (...) from the history, however, seems to have been forgotten by many who now and again return to controversies which more often than not are caused by ideological quarrels over religion, with true scholarship being too easily lost from sight. The paper reminds some of the history of the controversy in question and suggests that at least some of the current problems regarding evolution˗and˗ creation controversy may have already found their solutions. In part 1, “The Theory of Evolution and the Creation of the Human” it deals with the general issue of human origins. In part 2, “Monogenism and Original Sin” it explores the notion of the ‘first human’ as it is employed in biology and in theology, and shows its completely different meaning in these two realms of knowledge which helps to resolve the recurrent controversy over monogenism.

This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely ‘extinction of populations and species is bad’. Illustrating such debates in environmental ethics, the guiding question for this review concerns why – or when – anthropogenic extinctions are bad or wrong, which also includes the question of when that might not be the (...) case (i.e. which extinctions are even desirable). After providing an explanation of the disciplinary perspective taken (section “Introduction”), the concept of extinction and its history within that literature are introduced (section “Understanding extinction”). Then, in section “Why (or when) might anthropogenic extinctions be morally problematic?”, different reasons for why anthropogenic extinctions might be morally problematic are presented based on the loss of species’ value, harm to nonhuman individuals, the loss of valuable biological variety and duties to future generations. This section concludes by also considering cases where anthropogenic extinctions might be justified. Section “How to respond to extinctions?” then addresses a selection of topics concerning risks and de-extinction technologies. Finally, the section on “Extinction studies” introduces other viewpoints on the ethics of extinction from the extinction studies literature, followed by the “Conclusion”. (shrink)

A far-reaching and influential view in evolutionary biology claims that species are cohesive units held together by gene flow. Biologists have recognized empirical problems facing this view; after sharpening the expression of the view, we present novel conceptual problems for it. At the heart of these problems is a distinction between two importantly different concepts of cohesion, what we call integrative and response cohesion. Acknowledging the distinction problematizes both the explanandum of species cohesion and the explanans of gene (...) flow that are central to the view we discuss. We conclude by tracing four broader implications for the study and conceptualization of species. (shrink)

Darwinian ideas were developed and radically transformed when they were transmitted to the alien intellectual background of late nineteenth- and early twentieth-century China. The earliest references to Darwin in China appeared in the 1870s through the writings of Western missionaries who provided the Chinese with the earliest information on evolutionary doctrines. Meanwhile, Chinese ambassadors, literati and overseas students contributed to the dissemination of evolutionary ideas, with modest effect. The ‘evolutionary sensation’ in China was generated by the Chinese Spencerian Yan Fu’s (...) paraphrased translation and reformulation of Thomas Huxley’s 1893 Romanes Lecture ‘Evolution and ethics’ and his ‘Prolegomena’. It was from this source that ‘Darwin’ became well known in China – although it was Darwin’s name, rather than his theories, that reached Chinese literati’s households. The Origin of Species itself began to receive attention only at the turn of the twentieth century. The translator, Ma Junwu (1881–1940), incorporated non-Darwinian doctrines, particularly Lamarckian and Spencerian principles, into his edition of the Chinese Origin. This partially reflected the importance of the pre-existing Chinese intellectual background as well as Yan Fu’s progressive ‘evolutionary paradigm’. In this paper, I will elucidate Ma Junwu’s culturally conditioned reinterpretation of the Origin before 1906 by investigating his transformation of Darwin’s principal concepts. (shrink)

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.

Natural kinds, real kinds, or, following J.S Mill simply, Kinds, are thought to be an important asset for scientific realists in the non-fundamental (or “special”) sciences. Essential natures are less in vogue. I show that the realist would do well to couple her Kinds with essential natures in order to strengthen their epistemic and ontological credentials. I argue that these essential natures need not however be intrinsic to the Kind’s members; they may be historical. I concentrate on assessing the merits (...) of historical essential natures in a paradigm case of Kinds in the non-fundamental sciences: species. I specify two basic jobs for essential natures: 1) offering individuation criteria, and 2) providing a causal explanation of the Kind’s multiple projectable properties. I argue that at least in the case of species historical essences are fit for both tasks. The principled resistance to Kinds with historical essences should also be cleared. (shrink)

This paper reconsiders Ockham's critique of the species theory of cognition. As Ockham understands this theory, it says that the direct objects of cognition are mental representations, or species. According to many commentators, one of Ockham's main objections to this theory was that, if the direct objects of cognition are species rather than external objects, we will never be able to establish whether or not a given species is a veridical representation of the world. In this (...) paper I argue that this line of interpretation sits uneasily with Ockham's epistemology, and offer a new interpretation of Ockham's critique of species. (shrink)

Existence value refers to the value humans ascribe to the existence of something, regard­less of whether it is or will be of any particular use to them. This existence value based on preference satisfaction should be taken into account in evaluating activities that come with a risk of species extinction. There are two main objections. The first is that on the preference satisfaction interpretation, the concept lacks moral importance because satisfying people’s preferences may involve no good or well-being for (...) them. However, existence value can be based on a restricted version of the preference satisfaction theory, which is not vulnerable to the skeptical arguments about the link between preference satisfaction and well-being. The second objection is that even if preference satisfaction can be linked to well-being, understanding existence value in terms of individual preference satisfaction is incoherent, because existence value reflects disinterested preferences that involve no benefits to the individual. However, the fact that existence value may involve disinterested preferences does not threaten the coherence of the concept, but suggests that it does not fit smoothly into the “utilitarian” or “welfarist” framework it is commonly considered within. A pluralistic normative approach based on prima facie duties can be an alternative to standard utilitarian-style approaches for considering existence value in concrete cases involving a risk of species extinction, such as through deep sea mining.

This paper seeks to propose a direction of research based upon the transformation of Merleau-Ponty's thinking with respect to animal life over the course of his writings. In his earlier works, Merleau-Ponty takes up the position that “life” does not mean the same thing when applied to an animal and a human being because of the manner in which the “human dialectic” alters the human being's relation to life. In his later works, particularly in his lectures on nature, this position (...) softens so that the relationship between animals and humans becomes non-hierarchical, but remains essentially the same: there may be no “rupture” between humans and animals, but they are still essentially distinct insofar as all non-humans can be grouped into a single class of “animality.” I attempt to show that Merleau-Ponty fails to follow through with his most radical insights with respect to the relationships between living beings by preserving this distinction and suggest some ways in which we might today confront this problem through the works of Merleau-Ponty in a way that he did not. The proposal, then, is to take seriously “dialectical” biology and develop a Merleau-Pontian conception of species based upon the interrelations of living beings and their environments rather than focusing solely on organisms as discrete units. The conclusion then considers what the consequences of this understanding might be for our understanding of Merleau-Ponty's ontology in general. (shrink)

The species concept is one of the central concepts in biological science. Although modern systematics speculates about the existence of a complex hierarchy of nested taxa, biological species are considered particularly important for the active role they play in evolution. However, neither theoretical biologists nor philosophers of biology have come to an agreement about what a species is. In this chapter, we address two questions pertaining to biological species: (1) are they individuals or universals? and (2) (...) are they bona fide or fiat entities? In section The Species-as-Individuals View, we illustrate the reasons that have led many scholars to support the view that species are individuals. In the next two sections, we show that the relational concepts of species – on which the species-as-individuals view is based – provide neither necessary nor sufficient conditions for species membership. This seriously undermines the species-as-individuals view. In the section A Conceptualist Model for the Metaphysics of Species, we advance the proposal that species are fiat concepts (and thus, universal entities partially dependent on the human mind) carved in a multi-dimensional space representing the properties that the biological organisms possess. The final section concludes. (shrink)

This paper seeks to recover the function of universal history, which was to place particulars into relation with universals. By the 20th century universal history was largely discredited because of an idealism that served to lend epistemic coherence to the overwhelming complexity arising from universal history's comprehensive scope. Idealism also attempted to account for history's being "open"--for the human ability to transcend circumstance. The paper attempts to recover these virtues without the idealism by defining universal history not by its scope (...) but rather as a scientific method that provides an understanding of any kind of historical process, be it physical, biological or human. While this method is not new, it is in need of a development that offers a more robust historiography and warrant as a liberating historical consciousness. The first section constructs an ontology of process by defining matter as ontic probabilities rather than as closed entities. This is lent warrant in the next section through an appeal to contemporary physical science. The resulting conceptual frame and method is applied to the physical domain of existents, to the biological domain of social being and finally to the human domain of species being. It is then used to account for the emergence of human history's initial stage--the Archaic Socio-Economic Formation and for history' stadial trajectory--its alternation of evolution and revolution.

The so-called ‘‘species problem’’ has plagued evolution- ary biology since before Darwin’s publication of the aptly titled Origin of Species. Many biologists think the problem is just a matter of semantics; others complain that it will not be solved until we have more empirical data. Yet, we don’t seem to be able to escape discussing it and teaching seminars about it. In this paper, I briefly examine the main themes of the biological and philosophical liter- atures on the (...) species problem, focusing on identifying common threads as well as relevant differences. I then argue two fundamental points. First, the species problem is not primarily an empirical one, but it is rather fraught with philosophical questions that require—but cannot be settled by—empirical evidence. Second, the (dis-)solution lies in explicitly adopting Wittgenstein’s idea of ‘‘family resemblance’’ or cluster concepts, and to consider spe- cies as an example of such concepts. This solution has several attractive features, including bringing together apparently diverging themes of discussion among bio- logists and philosophers. The current proposal is con- ceptually independent (though not incompatible) with the pluralist approach to the species problem advocated by Mishler, Donoghue, Kitcher and Dupre ́, which implies that distinct aspects of the species question need to be emphasized depending on the goals of the researcher. From the biological literature, the concept of species that most closely matches the philosophical discussion pre- sented here is Templeton’s cohesion idea. (shrink)

This paper aims to offer a new argument in defence bacterial species pluralism. To do so, I shall first present the particular issues derived from the conflict between the non-theoretical understanding of species as units of classification and the theoretical comprehension of them as units of evolution. Secondly, I shall justify the necessity of the concept of species for the bacterial world, and show how medicine and endosymbiotic evolutionary theory make use of different concepts of bacterial (...) class='Hi'>species due to their distinctive purposes. Finally, I shall show how my argument provides a new source of defence for bacterial pluralism. (shrink)

Tom Stoppard’s 1966 play (and 1990 movie) /Rosencrantz and Guildenstern are Dead/ is a metatext – as a text, it interprets, builds upon, and refers to another text, Shakespeare’s Hamlet. Similarly, David N. Reznick’s /The Origin then and now: An interpretative guide to the Origin of Species/ (Princeton UP, 2010) is also a metatext. In this review, I turn to the history of science to evaluate whether Reznick’s book shares three families of virtues with Stoppard’s play: (i) brevity and (...) precision, (ii) intrigue and appeal, and (iii) a genuine value-add to the original.

Biological lineages move through time, space, and each other. As they do, they diversify, diverge, and grade away from and into one another. One result of this is genealogical discordance; i.e., the lineages of a biological entity may have different histories. We see this on numerous levels, from microbial networks, to holobionts, to population-level lineages. This paper considers how genealogical discordance impacts our study of species. More specifically, I consider this in the context of three framing questions: (1) How, (...) if at all, does genealogical discordance challenge, modify, or revise how we conceive of species? (2) How has growing appreciation of genealogical discordance impacted scientific practice? Of systematics in particular? (3) How do lineages at different levels diverge and diversify? All told, genealogical discordance enriches and complicates our taxonomic ontology, as well as the practice of reconstructing phylogenies. This presents both challenges and opportunities for the study of divergence and diversification. (shrink)

Some critics of invasion biology have argued the invasion of ecosystems by nonindigenous species can create more valuable ecosystems. They consider invaded communities as more valuable because they potentially produce more ecosystem services. To establish that the introduction of nonindigenous species creates more valuable ecosystems, they defend that value is provisioned by ecosystem services. These services are derived from ecosystem productivity, the production and cycling of resources. Ecosystem productivity is a result of biodiversity, which is understood as local (...) species richness. Invasive species increase local species richness and, therefore, increase the conservation value of local ecosystems. These views are disseminating to the public via a series of popular science books. Conservationists must respond to these views, and I outline a method of rejecting such arguments against controlling invasive species. Ecological systems are valuable for more than local productivity and biodiversity is not accurately described by a local species count. (shrink)

Abstract: In this study, we explore the possibility of classifying the plant species. We collected the plant species from Kaggle website. This dataset encompasses 544 samples, encompassing 136 distinct plant species. Recent advancements in machine learning, particularly Artificial Neural Networks (ANNs), offer promise in enhancing plant Species classification accuracy and efficiency. This research explores plant Species classification, harnessing neural networks' power. Utilizing a rich dataset from Kaggle, containing 544 entries, we develop and evaluate a neural (...) network model. Our neural network, featuring a single hidden layer, achieves remarkable results—a staggering 100% accuracy and a minute average error rate of 0.002. Beyond performance metrics, we delve into the intricacies of plant Species classification through feature importance analysis. The most influential features— Vegsout, durflow, semiros, pdias, begflow, wind, leafy, autopoll and insects— uncover the physiological traits underpinning accurate rice classification. This research contributes to advancing rice classification methods and highlights the potential of ANNs in optimizing agricultural practices, ensuring plant safety, and bolstering global trade.

The name ‘pluralism’ frequently rears its head in political philosophy, but theorists often have different things in mind when using the term. Whereas ‘reasonable pluralism’ refers to the fact of moral diversity among citizens of a liberal democracy, ‘value pluralism’ is a metaethical view about the structure of moral practical reasoning. In this paper, I argue that value pluralism is part of the best explanation for reasonable pluralism. However, I also argue that embracing this explanation is compatible with political liberalism’s (...) commitment to avoiding controversial premises. According value pluralism an explanatory role does not entail according it a justificatory one. What’s more, explaining reasonable disagreement in terms of reasonable disagreement about value weights opens up space for direct appeal to substantive values within political liberalism. In particular, promoting a substantive political value when doing so does not conflict with other values is unproblematic. (shrink)

According to Miranda Fricker, a hermeneutical injustice occurs when there is a deficit in our shared tools of social interpretation, such that marginalized social groups are at a disadvantage in making sense of their distinctive and important experiences. Critics have claimed that Fricker's account ignores or precludes a phenomenon I call hermeneutical dissent, where marginalized groups have produced their own interpretive tools for making sense of those experiences. I clarify the nature of hermeneutical injustice to make room for hermeneutical dissent, (...) clearing up the structure of the collective hermeneutical resource and the fundamental harm of hermeneutical injustice. I then provide a more nuanced account of the hermeneutical resources in play in instances of hermeneutical injustice, enabling six species of the injustice to be distinguished. Finally, I reflect on the corrective virtue of hermeneutical justice in light of hermeneutical dissent. (shrink)

We argue that the logical outcome of the cladistics revolution in biological systematics, and the move towards rankless phylogenetic classification of nested monophyletic groups as formalized in the PhyloCode, is to eliminate the species rank along with all the others and simply name clades. We propose that the lowest level of formally named clade be the SNaRC, the Smallest Named and Registered Clade. The SNaRC is an epistemic level in the classification, not an ontic one. Naming stops at that (...) level because there is no currently acceptable evidence for clades within it, not because no smaller clades exist. Later, included clades may be named. They would then become the SNaRCs, while the original SNaRC would keep its original name. We argue that all theoretical tasks of biology, in evolution and ecology, as well as practical tasks such as conservation assessment, are better approached using this rankless phylogenetic approach.

This collection of original essays--by philosophers of biology, biologists, and cognitive scientists--provides a wide range of perspectives on species. Including contributions from David Hull, John Dupre, David Nanney, Kevin de Queiroz, and Kim Sterelny, amongst others, this book has become especially well-known for the three essays it contains on the homeostatic property cluster view of natural kinds, papers by Richard Boyd, Paul Griffiths, and Robert A. Wilson.

Before the Darwinian revolution species were thought to be universals. Since then, numerous attempts have been made to propose new definitions. The twentieth-century German philosopher Nicolai Hartmann defined 'species' as an individual system of processes and a process of life of a higher-order. To provide a clear understanding of Hartmann's conception of species, I first present his method of definition. Then I look at Hartmann's Philosophie der Natur (1950) to present his concepts of "organism" and "species." (...) And I end the paper by pointing out two possible systematic inconsistencies.

For more than fifty years, taxonomists have proposed numerous alternative definitions of species while they searched for a unique, comprehensive, and persuasive definition. This monograph shows that these efforts have been unnecessary, and indeed have provably been a pursuit of a will o’ the wisp because they have failed to recognize the theoretical impossibility of what they seek to accomplish. A clear and rigorous understanding of the logic underlying species definition leads both to a recognition of the inescapable (...) ambiguity that affects the definition of species, and to a framework-relative approach to species definition that is logically compelling, i.e., cannot not be accepted without inconsistency. An appendix reflects upon the conclusions reached, applying them in an intellectually whimsical taxonomic thought experiment that conjectures the possibility of an emerging new human species.

The nature of “the self” has been one of the central problems in philosophy and more recently in neuroscience. This raises various questions: Can we attribute a self to animals? Do animals and humans share certain aspects of their core selves, yielding a trans-species concept of self? What are the neural processes that underlie a possible trans-species concept of self? What are the developmental aspects and do they result in various levels of self-representation? Drawing on recent literature from (...) both human and animal research, we suggest a trans-species concept of self that is based upon what has been called a “core-self” which can be described by self-related processing as a specific mode of interaction between organism and environment. When we refer to specific neural networks, we will here refer to the underlying system as the “core-SELF.” The core-SELF provides primordial neural coordinates that represent organisms as living creatures—at the lowest level this elaborates interoceptive states along with raw emotional feelings while higher medial cortical levels facilitate affective-cognitive integration . Developmentally, SRP allows stimuli from the environment to be related and linked to organismic needs, signaled and processed within core-self structures within subcorical-cortical midline structures that provide the foundation for epigenetic emergence of ecologically framed, higher idiographic forms of selfhood across different individuals within a species. These functions ultimately operate as a coordinated network. We postulate that core SRP operates automatically, is deeply affective, and is developmentally and epigenetically connected to sensory-motor and higher cognitive abilities. This core-self is mediated by SCMS, embedded in visceral and instinctual representations of the body that are well integrated with basic attentional, emotional and motivational functions that are apparently shared between humans, non-human mammals, and perhaps in a proto-SELF form, other vertebrates. Such a trans-species concept of organismic coherence is thoroughly biological and affective at the lowest levels of a complex neural network, and culturally and ecologically molded at higher levels of neural processing. It allows organisms to selectively adapt to and integrate with physical and social environments. Such a psychobiologically universal, but environmentally diversified, concept may promote novel trans-species studies of the core-self across mammalian species. (shrink)

Several philosophers have argued that if we examine our lives in context of the cosmos at large, sub specie aeternitatis, we cannot escape life's meaninglessness. To see our lives as meaningful, we have to shun the point of view of the cosmos and consider our lives only in the narrower context of the here and now. I argue that this view is incorrect: life can be seen as meaningful also sub specie aeternitatis. While criticizing arguments by, among others, Simon Blackburn, (...) Nicholas Rescher, and Thomas Nagel, I show that what determines assessments of the meaning of a life are the standards of meaningfulness one endorses rather than the size of the context in which that life is assessed. Employing non-demanding standards of meaningfulness to assess a life is compatible with examining it in the context of the cosmos at large. That is also the case if we accept Nagel's claim that to examine a life sub specie aeternitatis is to examine it externally, impersonally and objectively: life can be evaluated as meaningful also when under these perspectives if the standards of meaningfulness we adopt are not overly challenging. Nor does the contingency of our existence, realized sub specie aeternitatis, render our life meaningless. Contrary to a commonly accepted view, then, examining our lives sub specie aeternitatis does not necessitate that we see them as meaningless. (shrink)

It is sometimes claimed that as members of the species Homo sapiens we have a responsibility to promote the good of Homo sapiens itself (distinct from the good of its individual members). Lawrence Johnson has recently defended this claim as part of his approach to resolving the problem of future generations. We show that there are several difficulties with Johnson's argument, many of which are likely to attend any attempt to establish the moral considerability of Homo sapiens or (...) class='Hi'>species generally. Further, even if Homo sapiens were morally considerable, this would not ground an adequate response to the problem of future generations. The sort of moral considerability that would be appropriate to Homo sapiens, or species generally, would not be as robust nor have the implications that many have supposed. (shrink)

This paper explores the ethical dimensions of lionfish removal and provides an argument supporting hunting lionfish for consumption. Lionfish are an invasive species found around the world. Their presence has fueled management strategies that predominantly rely on promoting human predation and consumption. We apply rights-based ethics, utilitarian ethics, and ecocentric environmental ethics to the question of whether hunting and eating lionfish is ethical. After applying these perspectives, we argue that, from a utilitarian perspective, lionfish should be culled. Rights-based ethics, (...) on the other hand, are not applicable in this case, while ecocentric environmental ethics would support lionfish removal. (shrink)

Frontiers of Justice: Disability, Nationality, Species Membership, by Martha Nussbaum, Harvard University Press, 2006. How should we measure human development? The most popular method used to be to focus on wealth and income, as when international development agencies rank countries according to their per capita gross domestic product. Critics, however, have long noted shortcomings with this approach. Consider for example a wealthy person in a wheelchair: her problem is not a financial one, but a lack of access to public (...) spaces. Even if she were to hire porters to carry her in and out of stores and libraries, that would not really address her situation. There is a basic sense of dignity and self-respect that comes with being able to move around on one’s own. Even for a disabled millionaire, that will only be possible when public buildings are wheelchair accessible. To fully grasp what the handicapped need, we have to look beyond purely economic measures of well-being, and take into account the actual capabilities people can exercise in their daily lives. The example of the well-off person in a wheelchair illustrates what Martha Nussbaum calls the capabilities approach to human development. It was first pioneered in economics by Amartya Sen (who came up with the wheelchair example), and Nussbaum has for years been associated with a more philosophical variation, which uses the idea of capabilities to outline basic political principles. In Frontiers of Justice: Disability, Nationality, Species Membership Nussbaum takes this project even further, and applies the capabilities approach to issues of justice involving not only the disabled and the global poor, but animals as well.Yet for a philosophy called the capabilities approach, it is surprising how little theoretical work capabilities do in Nussbaum’s overall account.

Explains Aristotle's views on the possibility of continuous variation between biological species. While the Porphyrean/Linnean classification of species by a tree suggests species are distributed discretely, Aristotle admitted continuous variation between species among lower life forms.

Cross-species comparisons are benefited by compatible datasets; conclusions related to phylogenetic comparisons, questions on convergent and divergent evolution, or homologs versus analogs can only be made when the behaviors being measured are comparable. A direct comparison of the social function of physical contact across two disparate taxa is possible only if data collection and analyses methodologies are analogous. We identify and discuss the parameters, assumptions and measurement schemes applicable to multiple taxa and species that facilitate cross-species comparisons. (...) To illustrate our proposed guidelines for evaluating the role played by tactile contact in social behavior across disparate taxa, this paper presents data on mother-offspring relationships in the two species studied by the authors: chimpanzees (Pan troglodytes schweinfurthii) and dolphins (bottlenose and spotted, Tursiops truncatus and Stenella frontalis, respectively). Cross-species comparative studies allow for a more comprehensive assessment of the similarities and differences with respect to how animals traverse the relationships that form their social groups and societies.

In light of the phenomenon of multiple realizability, many philosophers wanted to preserve the mind-brain identity theory by resorting to a “narrow reductive strategy” whereby one (a) finds mental properties which are (b) sufficiently narrow to avoid the phenomenon of multiple realization, while being (c) explanatorily adequate to the demands of psychological theorizing. That is, one replaces the conception of a mental property as more general feature of cognitive systems with many less general properties, for example, replacing the conception of (...) pain as a general property across different species with a number of species-specific kinds of pain. Many critics focused on (c), arguing that species-specific properties are not explanatorily adequate because they do not capture what is common in pain across species. In this paper I focused on (b). I argued that if one carries the narrow reductive strategy out in such a way to avoid all multiple realizability that occurs within a species, for example, accommodating individual differences by postulating a more narrow pain-relative-to-an-individual-at-a-time, then the result is for all intents and purposes a claim about tokens and not types or properties at all (the position is now about individuals having properties at times, a structured token event). I also added an important point about explanation, viz., that properties-relative-to-individuals-at-times would not serve the explanatory goals of science by failing to generalize to other individuals.

Terrence Deacon has constructed a tome in which he unleashes his considerable learning in quest of several answers to the question, ‘What are we?’ He is uniquely qualified to take an approach which details the origin and development of, first, language, then the brain, and, lastly, their ‘co-evolution.’ Described on the jacket as ‘a world-renowned researcher in neuroscience and evolutionary anthropology,’ all of his background is called upon at various times to pull together the mass of data and supposition that (...) Deacon brings to the table. (shrink)

This chapter defends a pluralist understanding of species on which a normative species concept is viable and can support natural goodness evaluations. The central question here is thus: Since organisms are to be evaluated as members of their species, how does a proper understanding of species affect the feasibility of natural goodness evaluations? Philippa Foot has argued for a form of natural goodness evaluation in which living things are evaluated by how well fitted they are for (...) flourishing as members of their species, in ways characteristic of their species. She has further argued that assessments of moral goodness in humans are of the same evaluative form. However, natural goodness evaluations and, by extension, the natural goodness approach, do not garner justification in virtue of employing a scientifically privileged conception of species. The natural goodness approach is only justified given particular metaethical and normative commitments that are independent of naturalism, since the approach does not depend upon naturalism alone.

Book review of Richard A. Richards' The Species Problem: A Philosophical Analysis.

It has been widely argued that words are analogous to species such that words, like species, are natural kinds. In this paper, I consider the metaphysics of word-kinds. After arguing against an essentialist approach, I argue that word-kinds are homeostatic property clusters, in line with the dominant approach to other biological and psychological kinds.

Whitehead claims there is only one type of individual in the universe—the actual entity—but there are necessarily multiple tokens of this type. This turns out to be paradoxical. Nevertheless, a type of individuality that is necessarily plural because, for each token, relations to other tokens are constitutive is something familiar from ordinary language, everyday politics, and, not least, 19th century German social thought. Whitehead’s actual entity generalizes the notion of species-being we find in Fichte, Feuerbach, and Marx. The rationale (...) for the concept of species-being brings to light important social and political implications of Whitehead’s cosmology. (shrink)

this requirement for adaptations. Emergent characters are always potential adaptations. Not all selection processes produce adaptations, however. The key issue, in delineating a selection process, is the relationship between a character and fitness. The emergent character approach is more restrictive than alternative schemas that delineate selection..

The investigation of the act of Sex protrudes an intricate analysis more so if thus should be justified as an activity of the Mind and not purely physical. This philosophical endeavor investigates on the matter of incorporating Passion in the assertion of Sex as such that will beget Pleasure. In order for the proper direction setting of this inquest, the opus posited a literature review that is akin to the variables of this research. It is therefore qualifiable to assert the (...) variables of Passion, Sex, and Pleasure. As such, these properties allow the rudiments which shall be tackled on the explication. The researcher delved on the investigation on anatomizing Sex and even the Passions involve for it to be protruded in a state that is occupied by the Mind. The very purpose of the opus is to intricately expose the inner workings of the activities that ought to be done in banality. There is also an explication of thought experiments to highlight the integration to the epistemological property of the variable exposed in this endeavor. In the canopy of this research, the highlight is on the ontological property of the faculties ascertained and the epistemological qualification of the properties that are seemingly isolated from the Mind. It is therefore, phenomenological since it protrudes the nature of the properties as they exist in the current circumstance, as such it is less existential simply because what it ascertains is the circumstance upon which the action attributes itself to. -/- .

This afterword to Species and Beyond provides some reflections on species, with special attention to what I think the most significant developments have been in the thinking of biologists and philosophers working on species over the past 25 years, as well as some bad jokes.
