A large part of our exploration of the world consists in categorizing or classifying the objects and processes we encounter, both in scientific and everyday contexts. There are various, perhaps innumerable, ways to sort objects into different kinds or categories, but it is commonly assumed that, among the countless possible types of classifications, one group is privileged. Philosophy refers to such categories as natural kinds. Standard examples of such kinds include fundamental physical particles, chemical elements, and biological species. The term (...) natural does not imply that natural kinds ought to categorize only naturally occurring stuff or objects. Candidates for natural kinds can include man-made substances, such as synthetic elements, that can be created in a laboratory. The naturalness in question is not the naturalness of the entities being classified, but that of the groupings themselves. Groupings that are artificial or arbitrary are not natural; they are invented or imposed on nature. Natural kinds, on the other hand, are not invented, and many assume that scientific investigations should discover them. (shrink)

In this paper, we focus on the propensity toward identifying natural kinds with successful scientific categories in contemporary discussions of natural kinds within the philosophy of science. Success in this case is understood as the fulfillment of epistemic interests or goals in a given field of scientific research. The prevailing view is that, in order to have a theory of natural kinds that successfully captures current scientific practice, the relevant epistemic interests are the current interests of scientists working in a (...) particular field. In contrast, we concur with the Franklin-Hall (2015) that a wider range of possible interests needs to be taken into account, in order to avoid making natural kinds too dependent on the current stage of research. But unlike Franklin-Hall who suggests looking for an intersection between the interests and goals of current epistemic agents and our neighboring epistemic agents (the categorical bottleneck view), we advocate the view that all these different interests and goals need to be taken into account, and thus our view takes into account a much wider range of categories.

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)

In this paper, I discuss the question whether objective criteria could be provided for judging something to be a mental illness. I consider the two most prominent objectivist or naturalistic accounts of mental illness, evolutionary and bio-statistical account, which offer such a criterion by relying on the notion of biological function. According to such suggestions, illness is a condition in which there is dysfunciton in some feature of an organism. In this context, I consider different accounts for ascribing functions in (...) biologyand their relationship with the suggested accounts of illnesses. Special focus is placed on the objections according to which the ascription of functions, as envisaged in naturalistic accounts of illness, is incompatible with actual medical and psychiatric practice. I conclude that these objections are legitimate insofar we want to an account of illness that preserves the current practice of ascribing illness. However, the question remains, could a theory that tries to capture the actual medical practice be value-neutral, since our ordinary conception of illness is permeated with value judgments that indirectly enter into medical practice. In that respect, it seems that the requirement for pure objectivity is too strong and thus, it is not reasonable to expect that naturalistic accounts can satisfy it. (shrink)

Článek se věnuje srovnání podoby a vývoje sporu o vivisekce v Anglii a českých zemích, s důrazem na propojení protivivisekčního a ženského hnutí. První část textu na pozadí rozvoje medicíny popisuje okolnosti vzniku sporu a cestu, která vedla k přijetí první legislativy regulující experimenty se zvířaty. Druhá část představuje postoj F. P. Cobbeové, která je nejvýraznější ženskou postavu v tomto sporu. Třetí část mapuje situaci v českých zemích a nabízí důvody, které vysvětlují, proč se u nás v dané době organizované (...) protivivisekční hnutí nezformovalo. Autorka tvrdí, že klíčovou roli sehrálo pozitivní vnímání vědců, které pramenilo z jejich zapojení do procesu národního obrození. V poslední části textu jsou pak představeny názory na vivisekci dvou postav českého ženského hnutí na počátku 20. století, P. Moudré a E. Vozábové. Autorka ukazuje, že v dané době argumenty, které líčily experiment v medicíně jako nepotřebnou a neužitečnou metodu bádání, již nemohly být přesvědčivé. (shrink)
