This chapter examines philosophical issues surrounding the classification of mental disorders by the Diagnostic and Statistical Manual of Mental Disorders (DSM). In particular, the chapter focuses on issues concerning the relative merits of descriptive versus theoretical approaches to psychiatric classification and whether the DSM should classify natural kinds. These issues are presented with reference to the history of the DSM, which has been published regularly by the American Psychiatric Association since 1952 and is currently in its fifth edition. (...) While the first two editions of the DSM adopted a theoretical (psychoanalytic) and etiological approach to classification, subsequent editions of the DSM have adopted an atheoretical and purely descriptive (“neo-Kraepelinian”) approach. It is argued that largest problem with the DSM at present—viz., its failure to provide valid diagnostic categories—is directly related to the purely descriptive methodology championed by the DSM since the third edition of the DSM. In light of this problem, the chapter discusses the prospects of a theoretical and causal approach to psychiatric classification and critically examines the assumption that the DSM should classify natural kinds.

The objective of this paper is twofold. First, I present a framework called historical coherentism (Chang, 2004; Tal, 2016; Van fraassen 2008) and argue that it is the best epistemological framework available to tackle the problem of coordination, an epistemic conundrum that arises with every attempt to provide empirical content to scientific theories, models or statements. Second, I argue that the problem of coordination, which has so far been theorized only in the context of measurement practices (Reichenbach, 1927; Chang, 2001; (...) Tal, 2012; Van fraassen 2008), can be generalized beyond the philosophy of measurement. Specifically, it will be shown that the problem is embodied in classificatory practices and that, consequently, historical coherentism is well suited to analyze these practices as well as metrological ones. As a case study, I look at a contemporary debate in phylogenetics, regarding the evolutionary origin of a newly identified archaeal phylum called Methanonatronarchaeia. Exploring this debate through the lens of historical coherentism provides a detailed understanding of the dynamics of the field and a foothold for critical analyses of the standard rationale used by practitioners.

Abstract Recently, some philosophers of psychiatry (viz., Rachel Cooper and Dominic Murphy) have analyzed the issue of psychiatric classification. This paper expands upon these analyses and seeks to demonstrate that a consideration of the history of the Diagnostic and Statistical Manual of Mental Disorders (DSM) can provide a rich and informative philosophical perspective for critically examining the issue of psychiatric classification. This case is intended to demonstrate the importance of history for philosophy of psychiatry, and more generally, (...) the potential benefits of historically-informed approaches to philosophy of science.

The aim of this paper is to analyze, from a philosophical perspective, the scientific robustness of the construct of psychopathy as measured by the Psychopathy Checklist Revised that was developed by Robert Hare (1991; 2003). The scientific robustness and validity of classifications are topics of many debates in philosophy of science and philosophy of psychiatry more specifically. The main problem consists in establishing whether scientific classifications reflect natural kinds where the concept of a natural kind refers to the (...) existence of some objective divisions in nature that do not depend exclusively on subjective judgments of the classifier. The construct of psychopathy is especially interesting since the diagnosis of psychopathy has substantial social consequences. In the light of the recent debates regarding the problem of natural kinds in philosophy of psychiatry, we advocate the following distinction between two types of scientific classifications: natural and practical kinds. Natural kinds refer to those categories that are united by common causal mechanisms or properties. Practical kinds refer to categories that fulfill some practical classificatory goals such as prediction. We argue that the construct of psychopathy can fulfill the role of a practical kind. In addition, we contend that our current scientific knowledge about psychopathy does not allow us to conclude that this category is a natural kind. (shrink)

The article "Philosophia of Pure Mind: Declassification of the basic Biblical Mysteries" offers a tool for solving biblical mysteries — this is the philosophy of pure mind, which brings to life conceptual thinking with private and extremely general comparative concepts — concepts of practical mind and categories of pure mind. From these positions, an active study of the fundamental biblical mysteries is carried out, and not just their description or discussion. The investigation implies their comprehension related to the understanding (...) of reality, which we find in the first lines of the Torah, in which comparative concepts are represented by gradation (light and darkness, day and night) and orthogonal views, i.e. the relationship between two pairs of opposites (day and night — evening and morning): "And there was evening, and it was morning: day one." Thus, through the concepts of practical mind, the author reveals the general idea of the Creator, reflecting the harmony of nature in Words, each of which is a comparative concept of one kind or another. This is the key to uncovering the Biblical mysteries, namely: how the Word of God relates to the mystery of the fall, to the mysteries of the Book of Creation (Sefer Yetzira), the mystery of the Holy Trinity and the Sign of the Cross. Finally, how the proposed thinking helps to understand and gain a more complete understanding of the essence of these mysteries within the framework of one more general problem. Moreover, the root of all these problems, in my opinion, is that the mind thinking of people, given to them, as well as to all living things from nature through sensations, was supplemented by a person with a multi-valued reason thinking with classification concepts of natural language. In this connection, the natural human mind, through unambiguous comparative concepts, was supplanted by reason, apparently absent in animals. All of this unfolds against the background of three successive Reformations, which gave rise to three Abrahamic religions dating back to the patriarch of the Semitic tribes, Abraham. Whereas the beginning of these reforms is associated with the struggle of Moses for faith in the invisible God Yahweh, perceived as a civil war between the supporters of Moses as one part of the Jews with another part of them worshipping the God of their ancestors, the creator of all things — Ilohim. The article concludes with an understanding of the 4th Reformation, which aimed to create a modern synthetic religion with the help of AI. (shrink)

Jonathan Y. Tsou examines and defends positions on central issues in philosophy of psychiatry. The positions defended assume a naturalistic and realist perspective and are framed against skeptical perspectives on biological psychiatry. Issues addressed include the reality of mental disorders; mechanistic and disease explanations of abnormal behavior; definitions of mental disorder; natural and artificial kinds in psychiatry; biological essentialism and the projectability of psychiatric categories; looping effects and the stability of mental disorders; psychiatric classification; and the validity of (...) the DSM's diagnostic categories. The main argument defended by Tsou is that genuine mental disorders are biological kinds with harmful effects. This argument opposes the dogma that mental disorders are necessarily diseases that result from biological dysfunction. Tsou contends that the broader ideal of biological kinds offers a more promising and empirically ascertainable naturalistic standard for assessing the reality of mental disorders and the validity of psychiatric categories.

We undeniably live in an information age—as, indeed, did those who lived before us. After all, as the cultural historian Robert Darnton pointed out: ‘every age was an age of information, each in its own way’ (Darnton 2000: 1). Darnton was referring to the news media, but his insight surely also applies to the sciences. The practices of acquiring, storing, labeling, organizing, retrieving, mobilizing, and integrating data about the natural world has always been an enabling aspect of scientific work. Natural (...) history and its descendant discipline of biological taxonomy are prime examples of sciences dedicated to creating and managing systems of ordering data. In some sense, the idea of biological taxonomy as an information science is commonplace. Perhaps it is because of its self-evidence that the information science perspective on taxonomy has not been a major theme in the history and philosophy of science. The botanist Vernon Heywood once pointed out that historians of biology, in their ‘preoccupation with the development of the sciences of botany and zoology… [have] diverted attention from the role of taxonomy as an information science’ (Heywood 1985: 11). More specifically, he argued that historians had failed to appreciate how principles and practices that can be traced to Linnaeus constituted ‘a change in the nature of taxonomy from a local or limited folk communication system and later a codified folk taxonomy to a formal system of information science [that] marked a watershed in the history of biology’ (ibid.). A similar observation could be made about twentieth-century philosophy of biology, which mostly skipped over practical and epistemic questions about information management in taxonomy. The taxonomic themes that featured in the emerging philosophy of biology literature in the second half of the twentieth century were predominantly metaphysical in orientation. This is illustrated by what has become known as the ‘essentialism story’: an account about the essentialist nature of pre- Darwinian taxonomy that used to be accepted by many historians and philosophers, and which stimulated efforts to document and interpret shifts in the metaphysical understanding of species and (natural) classification (Richards 2010; Winsor 2003; Wilkins 2009). Although contemporary debates in the philosophy of taxonomy have moved on, much discussion continues to focus on conceptual and metaphysical issues surrounding the nature of species and the principles of classification. Discussions centring on whether species are individuals, classes, or kinds have sprung up as predictably as perennials. Raucous debates have arisen even with the aim of accommodating the diversity of views: is monism, pluralism, or eliminativism about the species category the best position to take? In addition to these, our disciplines continue to interrogate what is the nature of these different approaches to classification: are they representational or inferential roles of different approaches to classification (evolutionary taxonomy, phenetics, phylogenetic systematics)? While there is still much to learn from these discussions—in which we both actively participate—our aim with this topical collection has been to seek different entrypoints and address underexposed themes in the history and philosophy of taxonomy. We believe that approaching taxonomy as an information science prompts new questions and can open up new philosophical vistas worth exploring. A twenty-first century information science turn in the history and philosophy of taxonomy is already underway. In scientific practice and in daily life it is hard to escape the imaginaries of Big Data and the constant threats of being ‘flooded with data’. In the life sciences, these developments are often associated with the socalled bioinformatics crisis that can hopefully be contained by a new, interdisciplinary breed of bioinformaticians. These new concepts, narratives, and developments surrounding the centrality of data and information systems in the biological and biomedical sciences have raised important philosophical questions about their challenges and implications. But historical perspectives are just as necessary to judge what makes our information age different from those that preceded us. Indeed, as the British zoologist Charles Godfray has often pointed out, the piles of data that are being generated in contemporary systematic biology have led to a second bioinformatics crisis, the first being the one that confronted Linnaeus in the mid-18th century (Godfray 2007). Although our aim is to clear a path for new discussions of taxonomy from an information science-informed point of view, we continue where others in the history, philosophy, and sociology of science have already trod. We believe that an appreciation of biological taxonomy as an information science raises many questions about the philosophical, theoretical, material, and practical aspects of the use and revision of biological nomenclatures in different local and global communities of scientists and citizen scientists. In particular, conceiving of taxonomy as an information science directs attention to the temporalities of managing an accumulating data about classified entities that are themselves subject to revision, to the means by which revision is accomplished, and to the semantic, material, and collaborative contexts that mediate the execution of revisions.

The purpose of this chapter is to describe what we see as several important new directions for philosophy of medicine. This recent work (i) takes existing discussions in important and promising new directions, (ii) identifies areas that have not received sufficient and deserved attention to date, and/or (iii) brings together philosophy of medicine with other areas of philosophy (including bioethics, philosophy of psychiatry, and social epistemology). To this end, the next part focuses on what we call (...) the “epistemological turn” in recent work in the philosophy of medicine; the third part addresses new developments in medical research that raise interesting questions for philosophy of medicine; the fourth part is a discussion of philosophical issues within the practice of diagnosis; the fifth part focuses on the recent developments in psychiatric classification and scientific and ethical issues therein, and the final part focuses on the objectivity of medical research.

Animal mind philosophy and the related philosophy of language are rich and developing fields of philosophy. Enriched with the language of comparative concepts, they can become the threshold of a cumulative, verifiable strictly scientific "philosophy of pure mind", asserting a fundamentally new view of the problem of society, man and his place among other beings. My understanding of the mind through the prism of nonverbal and verbal thinking allowed me to get an idea of three completely (...) different stages in the development of the mind – reason, mind and wisdom. I understand reason as thinking by classification concepts of natural language, mind – as thinking by concrete scientific comparative concepts verified with the help of the senses. Whereas wisdom, understood by me in the light of "pure reason", is connected with the generalization of many particular comparative concepts. At the same time, I proceed from the fact that we are all perceiving beings, and our brain, being formed in the light of the relations of similarity and difference, perceives (comprehends – grasps) the energy present in the environment (energy in general), and converts it into sensory data. Presented by the Aristotle-Rotenfeld philosophical Matrix, in the form of concrete universal concepts of different types, they expand its cognitive capabilities step by step. Thus, with the help of spatial representations and integral visual images – drawings used by me, I show how to make nonverbal rational thinking of humans and animals verbal, expressing it in comparative terms.

Locke is often cited as a precursor to contemporary natural kind realism. However, careful attention to Locke’s arguments show that he was unequivocally a conventionalist about natural kinds. To the extent that contemporary natural kind realists see themselves as following Locke, they misunderstand what he was trying to do. Locke argues that natural kinds require either dubious metaphysical commitments (e.g., to substantial forms or universals), or a question-begging version of essentialism. Contemporary natural kind realists face a similar dilemma, and should (...) not appeal to Locke in their defense. (shrink)

John Wilkins and Malte Ebach respond to the dismissal of classification as something we need not concern ourselves with because it is, as Ernest Rutherford suggested, mere ‘‘stamp collecting.’’ They contend that classification is neither derivative of explanation or of hypothesis-making but is necessarily prior and prerequisite to it. Classification comes first and causal explanations are dependent upon it. As such it is an important (but neglected) area of philosophical study. Wilkins and Ebach reject Norwood Russell Hanson’s (...) thesis that classification relies on observation that is theory-laden and deny the need for aetiological assumptions and historical reconstruction to justify its arrangement. What they offer instead is a significant (albeit controversial) contribution to the philosophical literature on classification, a pre-theoretic natural classification based on the observation of patterns in data of ready-made phenomena. Their notion of ready-made phenomena rests on a conception of tacit knowledge or know-how. This is evident in their distinction between strong Theory-dependence and na ̈ıve theory-dependence. Their small t-theory-dependence permits patterns of observation that facilitate know-how but does not rely on a domain-specific explanatory theory of their aetiology. Wilkins and Ebach suggest classification differs from theory building in that it is passive (whereas theory building is active). Classification is possible just because it does not require the sieve of theory to capture classes that are ‘‘handed to you by your cognitive dispositions and the data that you observe’’ (p. 18). Finding regularities sans-theory is just something we do and can do without any prior theory about the underlying causes or origins of the resultant regularities. Luke Howard’s classification of clouds serves as an exemplar of a passive, theory-free classification system and the periodic table and the DSM help to illustrate this type of non-aetiological patterning. A recurrent theme is the nature of naturalness. For Wilkins and Ebach, the conception of naturalness is not one that is based on the generation or discovery of natural kind categories popular in both the traditional metaphysics of Mill and Wittgenstein as well as updated notions within philosophy of biology such as Boyd’s Homeostatic Property Cluster kinds. Instead, Wilkins and Ebach define the naturalness of classification as the falling into hierarchical patterns, aligning the search for natural arrangement with the aim of systematics, and as something that is grounded in a cognitive task or activity. However, they leave the question of realism v. antirealism open. ‘‘In natural classification...we must have real relations no matter how we might interpret ‘real’’’ (p. 70). There is tension with regard to their ontological commitments as they vacillate between constructive, operationalist, and realist approaches. Wilkins and Ebach initially define real as that which is causal and important (pp. 70–71), and later as that which ‘‘depends in no way upon a mind or observer’’ (p. 122). This makes their claim that there was ‘‘no real theory involved [in the pre-Darwinian classifications of Jussieu and Adanson]’’ (p. 64) difficult to interpret. Cont’d……. (shrink)

In the well-known intentionality quote of his Psychology from an Empirical Standpoint, Brentano characterises the mental phenomena through the following features: (i) the intentional inexistence of an object, (ii) the relation to a content, and (iii) the direction toward an object. The text argues that this characterisation is not general because the direction toward an object does not apply to the mental phenomena of sensation. The second part of the paper analyses the consequences that ensue from here for the Brentanian (...) classification of mental phenomena: in Brentano’s psychology one can distinguish two concepts of mental phenomena − the mental phenomenon in a broad sense and the mental phenomenon in a narrow sense; the former concept allows the separation of the mental from the physical, while the narrow concept allows the distinguishing of the main classes of mental phenomena. The third part of the paper shows that, with respect to sensation, the absence of a direction toward an object is compatible with both Brentano’s early taxonomies of philosophical sciences, and his early program for the establishment of a new, empirical and non-speculative philosophy. For this reason, I hold that intentionality is important for the foundation of both psychology, and empirical philosophy. (shrink)

The philosophy of mind is traditionally concerned with the study of mental processes, language, the representation of knowledge and the relation of the mind shares with the body; computational complexity theory is related to the classification of computationally solvable problems (be it via execution time, storage requirements, etc...). While there are well-established links between computer science in general & the philosophy of mind, many possible solutions to traditional problems in the philosophy of mind have not yet (...) been analyzed from the more specific lens of computational complexity theory. In his paper "Why Philosophers Should Care about Computational Complexity", Scott Aaronson argues that many conventional theories of epistemology & mind implicitly make the presupposition of omniscience (by supposing that knowing base facts means a knower necessarily understands derivative facts) - he proposes that computational complexity theory could explain why this is not the case. In this paper, I argue for a theory of mental representation & epistemology compatible with Aaronson's observations on complexity theory, overcoming that presupposition of omniscience. (shrink)

In our paper we investigate a difficulty arising when one tries to reconsiliateessentialis t’s thinking with classification practice in the biological sciences. The article outlinessome varieties of essentialism with particular attention to the version defended by Brian Ellis. Weunderline the basic difference: Ellis thinks that essentialism is not a viable position in biology dueto its incompatibility with biological typology and other essentialists think that these two elementscan be reconciled. However, both parties have in common metaphysical starting point and theylack (...) explicit track of methodological procedures. Methodological inquiry involves less demandingassumptions than metaphysical, and therefore it is justified to analyse abovementioned discrepancy between Ellis and other essentialist in this context. We do it by bottom-up investigation whichfocuses on the practice of taxonomists in the particular field of biology. A case study helps us todiscover four characteristics of biological typology practice: impossibility of algorithmization,relativity, subjectivity and conventionality. These features prove non-realistic and therefore anti-essentialistic character of biological classification. We conclude by saying that any essentialismrelated to the notion of biological kind cannot be regarded as justified by scientific enterprise of creating typologies. (shrink)

When our smartphones distract us, much more is at stake than a momentary lapse of attention. Our use of smartphones can interfere with the building-blocks of meaningfulness and the actions that shape our self-identity. -/- By analyzing social interactions and evolving experiences, Roholt reveals the mechanisms of smartphone-distraction that impact our meaningful projects and activities. Roholt’s conception of meaning in life draws from a disparate group of philosophers—Susan Wolf, John Dewey, Hubert Dreyfus, Martin Heidegger, and Albert Borgmann. Central to Roholt’s (...) argument are what Borgmann calls focal practices: dinners with friends, running, a college seminar, attending sporting events. As a recurring example, Roholt develops the classification of musical instruments as focal things, contending that musical performance can be fruitfully understood as a focal practice. -/- Through this exploration of what generates meaning in life, Roholt makes us rethink the place we allow smartphones to occupy in the everyday. But he remains cautiously optimistic. This thoughtful, needed interrogation of smartphones shows how we can establish a positive role for technologies within our lives. (shrink)

This paper demonstrates that Edmund Husserl’s frequently overlooked 1890 manuscript, “On the Logic of Signs,” when closely investigated, reveals itself to be the hermeneutical touchstone for his seminal 1891 Philosophy of Arithmetic. As the former comprises Husserl’s earliest attempt to account for all of the different kinds of signitive experience, his conclusions there can be directly applied to the latter, which is focused on one particular type of sign; namely, number signs. Husserl’s 1890 descriptions of motivating and replacing signs (...) will be respectively employed to clarify his 1891 understanding of the authentic and inauthentic presentations of numbers via number signs. Moreover, his schematic classification of replacement-signs in Semiotic will illuminate the reasons why he believed the number system to be necessary for the operation of replacing number signs.

This paper surveys Bolzano's Beyträge zu einer begründeteren Darstellung der Mathematik (Contributions to a better-grounded presentation of mathematics) on the 200th anniversary of its publication. The first and only published issue presents a definition of mathematics, a classification of its subdisciplines, and an essay on mathematical method, or logic. Though underdeveloped in some areas (including,somewhat surprisingly, in logic), it is nonetheless a radically innovative work, where Bolzano presents a remarkably modern account of axiomatics and the epistemology of the formal (...) sciences. We also discuss the second, unfinished and unpublished issue, where Bolzano develops his views on universal mathematics. Here we find the beginnings of his theory of collections, for him the most fundamental of the mathematical disciplines. Though not exactly the same as the later Cantorian set theory, Bolzano's theory of collections was used in very similar ways in mathematics, notably in analysis. In retrospect, Bolzano's debut in philosophy was a remarkably successful one, though its fruits would only become generally known much later. (shrink)

Scientists cannot devise theories, construct models, propose explanations, make predictions, or even carry out observations, without first classifying their subject matter. The goal of scientific taxonomy is to come up with classification schemes that conform to nature's own. Another way of putting this is that science aims to devise categories that correspond to 'natural kinds.' The interest in ascertaining the real kinds of things in nature is as old as philosophy itself, but it takes on a different guise (...) when one adopts a naturalist stance in philosophy, that is when one looks closely at scientific practice and takes it as a guide for identifying natural kinds and investigating their general features. This Element surveys existing philosophical accounts of natural kinds, defends a naturalist alternative, and applies it to case studies in a diverse set of sciences. This title is also available as Open Access on Cambridge Core. (shrink)

The article advances a new way of thinking about classifications in general and the classification of mental disorders in particular. By applying insights from measurement practice to the context of classification, I defend a notion of epistemic accuracy that allows one to evaluate and improve classifications by comparing different classifying methods to each other. Progress in classification arises from the mutual development of classification systems and classifying methods. Based on this notion of accuracy, the article illustrates (...) with an example how psychiatric classifications can be improved via circumscribed comparisons of different perspectives on mental disorders, without relying on complete models of their complex aetiology. When applying this strategy, the traditional opposition between symptom-based and causal approaches is of little consequence for making progress in the epistemic accuracy of psychiatric classification.

Identifying the necessary and sufficient conditions for individuating and classifying diseases is a matter of great importance in the fields of law, ethics, epidemiology, and of course, medicine. In this paper, I first propose a means of achieving this goal, ensuring that no two distinct disease-types could correctly be ascribed to the same disease-token. I then posit a metaphysical ontology of diseases—that is, I give an account of what a disease is. This is essential to providing the most effective means (...) of interfering with disease processes. Following existing work in the philosophy of medicine and epidemiology (primarily Christopher Boorse; Caroline Whitbeck; Alexander Broadbent), philosophy of biology (Joseph LaPorte; D.L. Hull), conditional analyses of causation (J.L. Mackie; David Lewis), and recent literature on dispositional essentialism (Stephen Mumford and Rani Anjum; Alexander Bird), I endorse a dispositional conception of disease. Following discussion of various conceptions of disease-identity, their relations to the clinical and pathological effects of the diseases in question, and how diseases are treated, I conclude (i) that diseases should be individuated by their causes, and (ii) that diseases are causal processes best seen as simultaneously acting sequences of mutually manifesting dispositions.

the proclivity of many people to classify human acts as good or bad calls into mind the import of ETHICS. The penchant for classification warrants the evaluation of the bases for saying that one is bad or good action. Normally, human act is ethical if it is in accordance with what one would relatively expect in view of the events or the circumstances and unethical if the action is not called for by the circumstances, or a person whose behavior (...) is disorderly and inconsistent. The same observations harbor on perception rather than on paradigms and frameworks which ethicists have somehow perfected to classify bad behavior into one division and good behavior into another. The study of ETHICS will therefore increase proficiency at least in moral decision making. Likewise, knowledge of the course will give students certain techniques for evaluating others’ action as moral or immoral, including their own. ETHICS is the science of action but the action herein alluded to is not the action that concerns those that are unconscious and spontaneous. Action here is that resulting from intellect and will herein referred to as human act. ETHICS is both a theoretical and a practical discipline. The language of ethics refers to rights, duties, and values. One of the goals of ethics is to explore the nature of moral experience, its universality, and its diversity. Another is to provide intellectual analysis of values, and value conflicts in order to define man’s duties. Also, it is oriented toward the determination of right decisions. In order to do that, it is necessary to go step by step, analyzing, first, the facts of the case, second, the values at stake, and third, the duties. In short, ETHICS has the very practical purpose of helping us to choose, decide, and act morally. It should enable us to discover defects in the action of others and to avoid defects in our own action. (shrink)

Known as the Darwin of the twenty-first century, the German biologist Ernst Walter Mayr (1904-2005) studied a great variety of subjects such as Ornithology, Genetics, Evolution, Classification, History, and Philosophy of Biology. This scientist was a giant of the previous century and an icon of Evolutionary Biology. He became famous for his Biological Species Concept and his conclusion that allopatry is the main cause for the origin of species. He provided a decisive contribution to the New Systematics and (...) was the pioneer of the punctuated equilibrium idea. Mayr was one of the main architects of the evolutionary synthesis as also of the Neo-Darwinian wave. Evaluated together, all of his works reveal several elements of his ambition – to organize a philosophical conception inherent for Biology. An assiduous defender of autonomous Biology, Mayr asserted that four sets of factors in Biology differ from those in the Exact Sciences: (I) refutation of essentialism, mechanism, vitalism, and teleology; (II) some physical principles cannot be applied to Biology; (III) absence of general laws in Biology; and (IV) basic principles of biology and their specific character cannot be applied to the inanimate world. The present study took as an axis a minor or even invisible theme from the Ernst Mayr literature and aims to analyze critically the theoretical and epistemological basis that subsidizes – or not– the affirmation that Biology is an autonomous Science. - O biólogo alemão Ernst Walter Mayr (1904-2005), conhecido como o Darwin do século XXI, trabalhou com uma grande variedade de temas: Ornitologia, Genética, Evolução, Classificação, História e Filosofia da Biologia. Esse cientista foi um dos gigantes do século XX e um ícone para a Biologia Evolutiva. Ficou famoso com o seu Conceito Biológico de Espécie e sua conclusão de que a alopatria era a principal causa da origem das espécies. Forneceu uma contribuição decisiva à Nova Sistemática, foi precursor da ideia de equilíbrio pontuado e um dos principais arquitetos da síntese evolutiva, bem como do movimento Neodarwinista. Quando avaliados em conjunto, seus trabalhos revelam os diversos elementos de sua ambição – organizar um corpo de concepções filosóficas próprias da Biologia. Defensor assíduo de uma Biologia autônoma, Mayr afirmou que há quatro conjuntos de fatores que diferenciam a Biologia do conjunto das Ciências Exatas: (I) refutação do essencialismo, do mecanicismo, do vitalismo e da teleologia; (II) convicção de que certos princípios da Física não podem ser aplicados à Biologia; (III) ausência de leis naturais universais em Biologia; e (IV) percepção do caráter único de certos princípios básicos da Biologia não aplicáveis ao mundo inanimado. O presente artigo tomou por eixo um tema aparentemente menor ou mesmo invisível na obra de Ernst Mayr e pretende realizar uma análise crítica acerca de suas bases teóricas e epistemológicas que subsidiaram – ou não – a afirmação da Biologia como uma Ciência autônoma.

The purpose of this study is to emphasize the reasons why manual classification of information materials should not be abandoned in current ICT era, particularly in Nigeria. Libraries are no exception to ICT applications, and we can observe how they have already altered library services and activities. Also, Information Technology (IT) has made it presence in almost every sphere of human activity including the library practice but to have fully automated classification scheme is yet to be implemented. Library (...) operation, such as cataloging, reference service, and the rest has a feel of this. For example, ICT has incorporated copy cataloguing into cataloguing operations, which libraries now employ instead of manual cataloging and also the arrival of online public access cataloguing (OPAC) was influenced by ICT, but this has not been fully infused into classification operations, which has kept the manual system of classification alive even in the face of ICT. Manual classification, on the other hand, cannot be abandoned because it is fundamental to the profession of librarianship. The classification of information resources is a foundation upon which librarianship is built, making classification a system as old as the library itself, as well as a practice that is unaffected by technological innovation. In addition, there are a variety of reasons in Nigeria that support the continued use of manual classification of information resources in the face of ICT. As a result, in this study we attempted to see the necessity of manual classification as well as the limitations of ICT in classification and the availing of manual classification in Nigeria.

This paper proposes a classificatory framework for disjunctivism about the phenomenology of visual perceptual experience. Disjunctivism of this sort is typically divided into positive and negative disjunctivism. This distinction successfully reflects the disagreement amongst disjunctivists regarding the explanatory status of the introspective indiscriminability of veridical perception and hallucination. However, it is unsatisfactory in two respects. First, it cannot accommodate eliminativism about the phenomenology of hallucination. Second, the class of positive disjunctivism is too coarse-grained to provide an informative overview of the (...) current dialectical landscape. Given this, I propose a classificatory framework which preserves the positive-negative distinction, but which also includes the distinction between eliminativism and non-eliminativism, as well as a distinction between two subclasses of positive disjunctivism. In describing each class in detail, I specify who takes up each position in the existing literature, and demonstrate that this classificatory framework can disambiguate some existing disjunctivist views.

This article uses the case study of ethnobiological classification to develop a positive and a negative thesis about the state of natural kind debates. On the one hand, I argue that current accounts of natural kinds can be integrated in a multidimensional framework that advances understanding of classificatory practices in ethnobiology. On the other hand, I argue that such a multidimensional framework does not leave any substantial work for the notion “natural kind” and that attempts to formulate a general (...) account of naturalness have become an obstacle to understanding classificatory practices.

This textbook has been written to discuss the fundamental problems of Greek Philosophy. There has been many philosophical Problems which Greek philosophers has discussed and examined with rational approach. The philosophical problems which we have mentioned in this book are: Greek Rationalism, Greek Naturalism, Greek Idealism, Greeks on human mind, Number theory and Greek Metaphysics. We have defined some significant issues like Greek atomism, Nihilism, Solipsism, Dogmatism, Sophism and Pluralism. Philosophy is the subject which studies the fundamental Problems (...) of the world. The problems which Philosophy studies are reality, existence, mind, thought, language, essence, experience, perception, knowledge, God, and so on. This book ‘Problems of Greek Philosophy’ is divided into six chapters while first Chapter ‘Introduction to western Philosophy’ deals with overall discussion and argumentation of western philosophy and also some valuable introductory information on Greek Philosophy. Second Chapter ‘Greeks on Nature’ attempts to discuss the lonian classification and examination of natural elements like water, air, Aperion, fire and reality. This chapter deals with the ultimate constituents of the natural stuff. Third chapter ‘Greek Rationalism’ deals with the role of reason in explanation of the world. Greek rationalists have used reason as the fundamental constituent of the universe. Fourth chapter ‘Number theory and Greek Metaphysics’ deals with the contribution of great mathematicians like Pythagoras and Zeno to the world. This chapter has highlighted the philosophy of number and metaphysics. Fifth Chapter ‘Greek Idealism’ highlights the philosophy of Greek idealists; Protagoras, Socrates and Plato. Sixth Chapter ‘Mind in Greek Philosophy’ deals with the concept of mind and thought in Greek philosophy. This section examines the contribution of Anaxagoras and Empedocles. (shrink)

The philosophy is an important factor of education policy like the religion, heritage, culture and customs of the society .It concerns on the mind and its implication in our daily life. Philosophy focus on Logic, Science, Epistemology, Ethics and Esthetics which are important branches of human thoughts. During the human history, philosophy organizes education and the societies revert to philosophy to regulate education policy. In ancient time, Plato and Aristotle’s educational policy was established for Athens. For (...) the Medieval, Al-Kindi, Al-Farabi, Al-Razi, Ibn Sina, Ibn Tufail, and Ibn Rushd contributed to setting education policy in Arab culture. John Locke, Jean-Jacques Rousseau, Karl Marx and John Dewey elaborated philosophical theories of education. Philosophy contributes to: suggesting education goals, provide the learning outcome, classification of topics and learning activities in educational institutions , and proposes an educational curriculum. In this research, I will address these factors focusing on the fact that our present civilized societies need a philosophical dimension in organizing education policy. I will rely on philosophical theories, as well as contemporary studies that have been written on education policy in developed countries. (shrink)

We propose a way to explain the diversification of branches of mathematics, distinguishing the different approaches by which mathematical objects can be studied. In our philosophy of mathematics, there is a base object, which is the abstract multiplicity that comes from our empirical experience. However, due to our human condition, the analysis of such multiplicity is covered by other empirical cognitive attitudes (approaches), diversifying the ways in which it can be conceived, and consequently giving rise to different mathematical disciplines. (...) This diversity of approaches is founded on the manifold categories that we find in physical reality. We also propose, grounded on this idea, the use of Aristotelian categories as a first model for this division, generating from it a classification of mathematical branches. Finally we make a history review to show that there is consistency between our classification, and the historical appearance of the different branches of mathematics. (shrink)

Aims and Methods: The general conceptual issues involved in psychiatric classification seem to be increasingly neglected in contrast to a focus on specific and empirical aspects which appear to have come to dominate the study of classification in the field. This article explores how the psychiatric field (in the UK and US) has chosen to analyse classification over time. Publication trends of articles in both The American Journal of Psychiatry and The British Journal of Psychiatry over a (...) fifty year period (1960-2010) can be viewed as indicators of the levels of interest within the psychiatric field toward classification. In an exploratory analysis, articles explicitly focusing on classification were counted and further sub-divided according to whether they focused on empirical or conceptual aspects and whether they adopted a general perspective or focused on a more specific aspect of classification. Results: Interest in classification was apparent in a minority of published articles (4.7% of all published articles). Interest in conceptual aspects dropped throughout the fifty years and was found to be considerably less than for empirical approaches which steadily increased over time. General papers about classification have been gradually on the decline and have been increasingly outnumbered by more specifically-focused articles. Clinical Implication: Classification, as a foundational endeavour within the psychiatric field, requires increased attention in the literature. This literature should address conceptual as well as empirical issues. (shrink)

This paper argues that early modern experimental philosophy emerged as the dominant member of a pair of methods in natural philosophy, the speculative versus the experimental, and that this pairing derives from an overarching distinction between speculative and operative philosophy that can be ultimately traced back to Aristotle. The paper examines the traditional classification of natural philosophy as a speculative discipline from the Stagirite to the seventeenth century; medieval and early modern attempts to articulate a (...) scientia experimentalis; and the tensions in the classification of natural magic and mechanics that led to the introduction of an operative part of natural philosophy in the writings of Francis Bacon and John Johnston. The paper concludes with a summary of the salient discontinuities between the experimental/speculative distinction of the mid-seventeenth century and its predecessors and a statement of the developments that led to the ascendance of experimental philosophy from the 1660s.

This dissertation is a contribution to the contemporary field of phenomenological psychopathology, or the phenomenological study of psychiatric disorders. The work proceeds with two major aims. The first is to show how a phenomenological approach can clarify and illuminate the nature of psychopathology—specifically those conditions typically labeled as major depressive disorder and bipolar disorder. The second is to show how engaging with psychopathological conditions can challenge and undermine many phenomenological presuppositions, especially phenomenology’s status as a transcendental philosophy and its (...) corresponding anti-naturalistic outlook. In the opening chapter, I articulate the three layers of the subject matter of phenomenological research—what I refer to as “existentials,” “modes,” and “prejudices.” As I argue, while each layer contributes to what we might call the “structure” of human existence, they do not do so in the same way, or to the same degree. Because phenomenological psychopathology—and applied phenomenology in general—aims to characterize how the structure of human existence can change and alter, it is paramount that these layers be adequately delineated and defined before investigating these changes. In chapters two through five, I conduct hermeneutic and phenomenological investigations of psychopathological phenomena typically labeled as major depressive disorder or bipolar disorder. These investigations address the affective aspects of depression and mania, and the embodied aspects of depression. In addition to clearly articulating the nature of these phenomena, I show how certain psychopathological conditions involve changes in the deepest or most fundamental layer of human existence—what I refer to as existentials. As I argue, many of the classical phenomenologists (including Husserl and Heidegger) believed that these structural features were necessary, unchanging, and universal. However, this presupposition is challenged through the examination of psychopathological and neuropathological conditions, undermining the status of phenomenology as a transcendental philosophy. While this challenge to classical phenomenology is only sketched in the early chapters, in chapters six and seven I develop it in more detail in order to achieve two distinct ends. In chapter six I argue that psychopathology and neuropathology not only challenge phenomenology’s status as a transcendental philosophy, but also supply a key to developing a phenomenological naturalism (which I contrast with a naturalized phenomenology). Phenomenological naturalism, as I articulate it, is a position in which phenomenology is not subsumed by the metaphysical and methodological framework of the natural sciences, but nonetheless maintains the capacity to investigate how the natural world stands independent of human subjectivity (and how events in the natural world can bring about changes in the most fundamental structures of human existence). In the seventh chapter I argue that a phenomenology in which existentials are contingent and variable rather than necessary and unchanging allows phenomenologists to contribute to new dimensional approaches to psychiatric classification. Rather than begin from distinct categories of disorder, these approaches begin from distinct core features of human existence. These features, referred to as either dimensions or constructs, can vary in degree and are studied in both normal and pathological forms. (shrink)

In this essay, I argue for the rejection of Vihvelin's ‘Three-fold Classification’ , a nonstandard taxonomy of free-will compatibilism, incompatibilism, and impossibilism. Vihvelin is right that the standard taxonomy of these views is inadequate, and that a new taxonomy is needed to clarify the free-will debate. Significantly, Vihvelin notes that the standard formal definition of ‘incompatibilism’ does not capture the historically popular view that deterministic laws pose a threat to free will. Vihvelin's proposed solution is to redefine ‘incompatibilism.’ However, (...) Vihvelin's formal definition of ‘incompatibilism’ is flawed according to her own arguments. In addition, Vihvelin's characterization of ‘compatibilism’ is incomplete, and at least two important free-will views are missing from her proposed taxonomy. Given the problems with Vihvelin's arguments for 3-FC, her novel view of the dialectic between the major free-will views lacks support. (shrink)

The article "Philosophy is the unborn child of science: in search of a universal commonly used language" explores the problem of creating a universal philosophical language that includes not only the language of classification concepts of natural language that define people's reasoning thinking, but also the language of comparative concepts, which is the basis their mind and wisdom. At the same time, the author divides comparative concepts into two parts, the first of which is determined by particular concepts (...) – concepts of practical mind peculiar to natural and exact sciences, while the second part is determined by extremely general concepts – categories of pure mind, which were supposed to become the beginnings of philosophy as a verifiable rigorous science. Along with the majority of thinking people, the author sees that as a cumulative rigorous science, philosophy has not taken place, and therefore considers it an unborn child of science. In this regard, he analyzes various philosophical traditions and comes to the conclusion that "everything is known in comparison." Therefore, the basis of a language that would facilitate effective communication between different philosophical directions, as well as between natural and humanitarian disciplines, can only be the language of comparative concepts. As a result of using the four types of opposition identified by Aristotle as the principles of philosophy: "contradictory", "correlated", "opposite", "deprivation and possession", the author built a philosophical Matrix from which he approaches the creation of such a universal language. At the same time, the Matrix includes other more complex comparative concepts than those of Aristotle – concepts of pure mind found by the author in the teachings of outstanding thinkers of the past: Lao Tzu, Pythagoras, Heraclitus and K. Marx, but today misunderstood or forgotten. The comparative concepts returned from oblivion, in the author's opinion, represent a valuable contribution to many areas of philosophy and linguistics, and can be useful for philosophers, psychologists, educators, linguists and anyone interested in the problem of language in philosophy and their undeniable role in the development of mind and wisdom.

Interest in idealism has increased substantially since the publication of Sprigge’s Vindication of Absolute Idealism in 1984,1 and again with more vigor over the last decade in the context of the mind-body problem and panpsychism. This will probably not come as a surprise to objective idealists, among which Vittorio Hosle has proposed that philosophy cycles through stages with some form of idealism as end point of each cycle.2 More recently, David Chalmers mused about a corresponding development in the worldview (...) of single individuals from materialism over dualism and panpsychism to idealism.3 Traditional accounts of idealism include for instance those of Plato, Plotinus, Leibniz, Berkeley, or Hegel. An overview of contemporary approaches is given in the article by Chalmers, where he mentions amongst others a recent collection of essays on idealism,4 but also for instance the (recently extended5) works of Philip Goff on Russellian monism.6 A more classically oriented collection of works on idealism was edited by Hosle and Suarez Muller.7 In his article ‘Idealism and the Mind-Body Problem’, David Chalmers presents a classification of possible versions of idealism with the goal of assessing the prospects of idealism in the context of the mind-body problem without having to pay too much attention to its ‘historical baggage’. This goal seems to me highly laudable and the resulting classification an important contribution to the contemporay discussion. In addition, the conclusions drawn from the subsequent analysis seem very plausible from the viewpoints of dualistic, panpsychistic and similar thinking. I nevertheless believe that the presented classification is not really adequate to capture the core of traditional idealistic thinking, which in turn leads to somewhat distorted conclusions about the opportunities for idealism to play a role for understanding the mind-body problem: First, the distinction between micro- macro- and cosmic idealism ist not fitting well into the idealistic venture. Instead, idealism is artificially reduced to a bad alternative to panpsychism. Secondly, the initially mentioned, but afterwards not discussed again difference between subjectinvolving and non-subject-involving idealism needs to be further extended, to account for the special role of subjects in traditional accounts of objective idealism. To elaborate on this, I will first give a short summary of Chalmers classification and some of the mentioned problems with idealism. Afterwards I will come back to my two objections in more detail.

This chapter studies classifications of warfare in Master Wu, The Four Canons, and Master Wen. In sections one through three, I analyze the classifications in their original contexts. How do they relate to the texts in which they appear? In what way does each classification feed into the overall philosophy of the text? In section four, I compare the three classifications. What are their similarities and differences? In section five, I discuss the possibility of a relationship between the (...) three classifications. Are any perhaps directly and demonstrably influenced by another? I hypothesize that the classification of warfare in Master Wu may have served as a source for those in The Four Canons and Master Wen. In section six, I explore the development of classifications of warfare in writings from the Warring States period to the early Han dynasty. How did the classifications evolve from military–strategic writings to texts of politico–philosophical nature? Finally, in section seven, I survey the impact of classifications on the wider political debate on warfare in those days. Did classifications influence the debate? If so, to what effect? (shrink)

Winner of the 2020 Essay Competition of the International Social Ontology Society. -/- Ian Hacking uses the looping effect to describe how classificatory practices in the human sciences interact with the classified people. While arguably this interaction renders the affected human kinds unstable and hence different from natural kinds, realists argue that also some prototypical natural kinds are interactive and human kinds in general are stable enough to support explanations and predictions. I defend a more fine-grained realist interpretation of interactive (...) human kinds by arguing for an explanatory domain account of the looping effect. First, I argue that knowledge of the feedback mechanisms that mediate the looping effect can supplement, and help to identify, the applicability domain over which a kind and its property variations are stably explainable. Second, by applying this account to cross-cultural case studies of psychiatric disorders, I distinguish between congruent feedback mechanisms that explain matches between classifications and kinds, and incongruent feedback mecha- nisms that explain mismatches. For example, congruent mechanisms maintain Western auditory experiences in schizophrenia, whereas exporting diagnostic labels inflicts incongruence by influencing local experiences. Knowledge of the mechanisms can strengthen explanatory domains, and thereby facilitate classificatory adjustments and possible interventions on psychiatric disorders. (shrink)

In this essay several challenges are raised to the project of classifying Śāntideva’s ethical reasoning given in his Bodhicaryāvatāra, or Guide to the Way of the Bodhisattva, as a species of ethical theory such as consequentialism or virtue ethics. One set of difficulties highlighted here arises because Śāntideva wrote this text to act as a manual of psychological transformation, and it is therefore often difficult to determine when his statements indicate his own ethical views. Further, even assuming we can identify (...) a set of statements that accurately portray the moral position of Śāntideva, it is argued that these statements underdetermine which foundational normative theory should be ascribed to him.

In this article, I will reconstruct the monocausal model and argue that modern 'multifactorial diseases' are not monocausal by definition. 'Multifactorial diseases' are instead defined according to a constitutive disease model. On closer analysis, infectious diseases are also defined using the constitutive model rather than the monocausal model. As a result, our classification models alone cannot explain why infectious diseases have a universal etiology while chronic and noncommunicable diseases lack one. The explanation is instead provided by the nineteenth-century germ (...) theorists. (shrink)

The question of how psychiatric classifications are made up and to what they refer has attracted the attention of philosophers in recent years. In this paper, I review the claims of authors who discuss psychiatric classification in terms referring both to the philosophical tradition of natural kinds and to the sociological tradition of social constructionism — especially those of Ian Hacking and his critics. I examine both the ontological and the social aspects of what it means for something to (...) be a mental disorder, and how the ontological status of these disorders hinges on social causation. Finally, I conclude by suggesting a way in which the biological and the social may be reconciled in an integrative model of variation in psychiatric disorder. (shrink)

Oulis pointed out that there is a great deal of interest in specific mechanisms relating to mental disorders and that these mechanisms should play a role in classification. Although specific mechanisms are important, more attention should be given to general theories. The following example from Salmon illustrates the difference.

proposition. Universal proposition is defined as the proposition in which the relation between the subject term and the predicate term is without any condition, in which the predicate is either affirmed or denied of the subject unconditionally. In nyaya logic the term vyapti is a universal proposition or invariable relation between the middle term (linga/hetu) and the major term (sadya) . According to the category of relation propositions are divided into categorical and the conditional. Although proposition is a logical entity (...) which is an assertion, either affirm or deny the subject. Truth and falsity are the values of proposition. Universal proposition is of two kinds: universal affirmative proposition and universal negative proposition while universality is the quantity of the subject and affirmation or negation is the quality of the proposition. Anumana (inference) is the knowledge of the objects which follows some other knowledge. In nyaya logic Inference is a combined deductive-inductive reasoning consisting of at least three categorical propositions and in it there are at least three propositions consisting of three terms, viz. the paksa or minor term about which we infer something, the sadhya or major term which inferred object, and the linga(probans) or sadana or middle which is invariably related to the major, and is present in the minor. Indian inference resembles to the categorical syllogism of western logic. In nyaya logic inference consisting of three propositions the first proposition is the conclusion of the syllogism , the second is the minor premise and last the major premise which is totally opposite of western logic. Syllogism of nyaya logic contains five propositions, called its Avayavas or members. These are pratijna, hetu, udarana, upanaya, and nigamana. Middle term have five characteristics in order to make five Figures of syllogism as Figure is the form of the syllogism. These five characteristics, or at least four of them , must be found in the middle term of a valid inference. If not, there will be fallacies(error in reasoning). Nyayikas give us three classifications of inference. According to first inference is of two kinds, namely, svartha and parartha. According to another inference is of three kinds, purvavat, sesavat and samanyatodrsta. According to third classification inference is distinguished into kevalanvayi, kevala-vyatireki and anvaya-vyatireki. (shrink)

In the seventeenth to the eighteenth centuries, East Asia witnessed new academic trends emphasizing social practice and reform over theoretical considerations. These trends gave rise to Silhak 實學 (“Practical Learning”) in Korea in the late Joseon dynasty, Qixue 氣學 (“Learning of Vital Forces”) in China in the late Ming and early Qing dynasties, and Kogaku 古學 (“Ancient Learning”) in Japan in the Edo period. A concept of “East Asian Silhak 東亞實學 (East Asian Practical Learning)” can be conceived in the context (...) of strengthening the Confucian statecraft in the seventeenth and eighteenth centuries. However, in the nineteenth and twentieth centuries, this academic trend, so-called East Asian Practical Learning, was manifested in the form of “pursuit of West-centered modernity” in the three East Asian countries. It would be appropriate to understand it as a “modern transformation of East Asian Confucian thought” rather than as the Confucian statecraft in the context of Confucianism. When attempting to incorporate the ideological transformation of Confucianism in East Asia in the nineteenth and twentieth centuries into the concept of Silhak, there are issues such as: the conceptual confusion between Silhak of the late Joseon dynasty of Korea and Kaozhengxue 考證學 (“Evidential Learning”) of the Qing dynasty of China; and their pursuit of modernity based on the premise of anti-Zhuzi studies. Given these complexities, this article underscores that the genesis of New Silhak in twenty-first-century East Asia lies in the simultaneous relationship between Zhuzi studies and Silhak, reflecting the Confucian ideal of neisheng waiwang 內聖外王 (“inner sage and outer king”).

Classical presentations of the Buddhist path prescribe the cultivation of various good qualities that are necessary for spiritual progress, from mindfulness and loving-kindness to faith and wisdom. Examining the way in which such qualities are described and classified in early Buddhism—with special reference to their treatment in the Visuddhimagga by the fifth-century Buddhist thinker Buddhaghosa—the present article employs a comparative method in order to identify the Buddhist catalog of virtues. The first part sketches the characteristics of virtue as analyzed by (...) neo-Aristotelian theories. Relying on these accounts, the second part considers three lists from early Buddhism as possible catalogs of virtue: the components of ethical conduct, the 37 factors that contribute to awakening, and the wholesome or beautiful mental factors. I then raise the question of why the Buddhist tradition developed several classifications of virtue, whereas the Western tradition of virtue ethics used a single category. Appealing to the connection between the virtues and living well in the eudaimonistic version of virtue ethics, I propose that one of the reasons why Buddhism developed multiple lists of virtues is its pluralistic acceptance of different modalities of living well and associated practices, in MacIntyre’s sense of the term. These modalities and practices are not equal, but are ordered hierarchically. Accordingly, I conclude that Buddhist ethics ought to be seen as a pluralist-gradualist system rather than a universalist theory. (shrink)

Contemporary psychiatry finds itself in the midst of a crisis of classification. The developments begun in the 1980s—with the third edition of the Diagnostic and Statistical Manual of Mental Disorders —successfully increased inter-rater reliability. However, these developments have done little to increase the predictive validity of our categories of disorder. A diagnosis based on DSM categories and criteria often fails to accurately anticipate course of illness or treatment response. In addition, there is little evidence that the DSM categories link (...) up with genetic findings, and even less evidence that they... (shrink)

This paper delves into the character concept as applied to reproduction. Our argument is that the prevailing functional-adaptationist perspective falls short in explaining the evolution of reproductive traits, and we propose an alternative organismal-relational approach that incorporates the developmental and interactive aspects of reproduction. To begin, we define the functional individuation of reproductive traits as evolutionary strategies aimed at enhancing fitness, and we demonstrate how this perspective influences the classification of reproductive characters and modes, the comprehension of shared traits (...) as resulting from conflicts of evolutionary interest between individuals, and the explanation of reproductive diversity. After outlining the shortcomings of this framework, we introduce an organismal-relational approach grounded in evolutionary developmental studies of reproduction. This view provides a revised classification for reproductive characters and modes and offers a new understanding of interorganismal traits that takes into account their inherently relational nature. Lastly, we present the research agenda that emerges from this approach, which addresses the core explanatory gaps left by the adaptationist perspective, including the explanation of reproductive homologies and homoplasies, the developmental constraints associated with the evolution of reproductive modes, and the evolvability of reproductive characters.

The disciplinary differentiation of sciences attracted Leibniz’s attention for a long period of time. From nowadays prospects it looks very well grounded as soon as in Leibniz’s manuscripts a modern scholar finds clue ideas of any research field which would tempt him to consider Leibniz as one of the founders of this particular discipline. We argue that this is possible only in retrospection and would significantly distort the essence of Leibniz’s epistemology. Our approach implies, in contrary, the investigation of the (...) Leibniz doctrine of signs on the background of the related philosophical problem, that of expression. The choice of semiotics is justified by the fact that it took a central place in his theoretical constructions, both those of natural sciences and of philosophy. In Leibniz system of knowledge the concept of notes (notae) and sings (signa) served a theoretical foundation of his most important and long-life aspiration to build up practical science of universal characteristics (characteristica universalis). In his eyes this practical science was the science of sciences (Scientia scientiarum), and we can consider it as the matrix for all possible scientific knowledge. (shrink)

scientific progress, natural philosophy of the Late Medieval Period is seen as playing the role of apologetics. For philosophers of science, with their repudiation of metaphysics, the task of providing a rational reconstruction of how scientific progress has occurred is nigh on impossible. Even explanations such as the Popperian and the Kuhnian strain under great difficulty and provide only partly satisfactory results. In his “Logik der Forschung” (1934) Karl Raimund Popper argues that metaphysics plays an accidental part in the (...) emergence of new scientific ideas. Correspondingly, in “Structure of Scientific Revolutions” (1962), by carrying out theoretical interpretations and classification of empirical facts without their metaphysical premises, Thomas Kuhn comes to the conclusion that natural science was formed under the influence of erroneous interpretations of Aristotelian natural philosophy presented by medieval natural philosophers. These are some of the reasons why medievalists are still made to defend late medieval natural philosophy from shallow convictions that at medieval universities nothing of any significance to contemporary science and philosophy took place at all. Seeking to render a fragment of a coherent reconstruction of the development of natural philosophy, I will investigate one idea of late medieval philosophy – the explanation of motion (impetus). The main statement of the paper holds that the ideas of late medieval natural philosophy have a decisive significance for the development of modern natural science instead of accidental or negative one. In the paper, following Aristotelian philosophical approach, premises of Jean Buridan’s theory of impetus will be exposed. Then, debates over the explanation of projectile motion are going to be presented, and finally, the necessary significance of this metaphysical idea on the modifications of natural philosophy is going to be ascertained.

Discussions over whether these natural kinds exist, what is the nature of their existence, and whether natural kinds are themselves natural kinds aim to not only characterize the kinds of things that exist in the world, but also what can knowledge of these categories provide. Although philosophically critical, much of the past discussions of natural kinds have often answered these questions in a way that is unresponsive to, or has actively avoided, discussions of the empirical use of natural kinds and (...) what I dub “activities of natural kinding” and “natural kinding practices”. The natural kinds of a particular discipline are those entities, events, mechanisms, processes, relationships, and concepts that delimit investigation within it—but we might reasonably ask: How are these natural kinds discovered?, How are they made?, Are they revisable?, and Where do they come from? A turn to natural kinding practices reveals a new set of questions open for investigation: How do natural kinds explain through practice?, What are natural kinding practices and classifications and why should we care?, What is the nature of natural kinds viewed as a set of activities?, and How do practice approaches to natural kinds shape and reconfigure scientific disciplines? Natural kinds have traditionally been discussed in terms of how they classify the contents of the world. The metaphysical project has been one which identifies essences, laws, sameness relations, fundamental properties, and clusters of family resemblances and how these map out the ontological space of the world. But actually how this is done has been less important in the discussion than the resultant categories that are produced. I aim to rectify these omissions and suggest a new metaphysical project investigating kinds in practice. (shrink)
