Homology is among the most important comparative concepts in biology. Today, the evolutionary reinterpretation of homology is usually conceived of as the most important event in the development of the concept. This paradigmatic turning point, however important for the historical explanation of life, is not of crucial importance for the development of the concept of homology itself. In the broadest sense, homology can be understood as sameness in reference to the universal guarantor so that in this sense the different concepts (...) of homology show a certain kind of “metahomology”. This holds in the old morphological conception, as well as in the evolutionary usage of homology. Depending on what is (or was) taken as a guarantor, different types of homology may be distinguished (as idealistic, historical, developmental etc.). This study represents a historical overview of the development of the homology concept followed by some clues on how to navigate the pluralistic terminology of modern approaches to homology.

As well as aiming to revive interest in Meinong's thought, this book challenges many of the most widespread assumptions of philosophical logic.

Abstract Western philosophical and psychological thinking lacks an accepted theory of human personality; it has produced conflicting and inadequate notions, such as the religious one of a soul, the vague concept of the ?mind? and biological theories basing their understanding of man on the functions of the nervous system, particularly the brain, or dealing with his mental dimension only in terms of behavioural patterns. This paper explores the notions of personality in Indian systems and finds that virtually all of them (...) understand it, despite differing terminology, as a fluid complex of functions or living forces characterised by intrinsic intelligence and coordinated by a dynamic structural principle, operating on three levels of reality: phenomenal material, phenomenal immaterial and noumenal or absolute. One can say that the Indian tradition fully appreciated the complexity of the problem and produced theories of personality which are more comprehensive than western ones and merit study as well as attention from the point of view of contemporary creative philosophical thinking.

Free logic, an alternative to traditional logic, has been seen as a useful avenue of approach to a number of philosophical issues of contemporary interest. In this collection, Karel Lambert, one of the pioneers in, and the most prominent exponent of, free logic, brings together a variety of published essays bearing on the application of free logic to philosophical topics ranging from set theory and logic to metaphysics and the philosophy of religion. The work of such distinguished philosophers as (...) Bas van Fraassen, Dana Scott, Tyler Burge, and Jaakko Hintikka is represented. Lambert provides an introductory essay placing free logic in the logical tradition beginning with Aristotle, developing it as the natural culmination of a trend begun in the Port Royal logic of the 1600s, and continuing through current predicate logic--the trend to rid logic of existence assumptions. His Introduction also provides a useful systematic overview of free logic, including both a standard syntax and some semantical options. (shrink)

Free logic is an important field of philosophical logic that first appeared in the 1950s. J. Karel Lambert was one of its founders and coined the term itself. The essays in this collection explore the philosophical foundations of free logic and its application to areas as diverse as the philosophy of religion and computer science. Amongst the applications on offer are those to the analysis of existence statements, to definite descriptions and to partial functions. The volume contains a proof (...) that free logics of any kind are non-extensional and then uses that proof to show that Quine's theory of predication and referential transparency must fail. The purpose of this collection is to bring an important body of work to the attention of a new generation of professional philosophers, computer scientists and mathematicians. (shrink)

In the Philebus, Plato elaborates an image of our soul as a book where a scribe and a painter are constantly at work. This book examines the implicit premises of this image and aims at overcoming the general polarity of ancient phantasia and modern imagination.

This article considers the uncommon situation surrounding the acceptance of Darwinism in nineteenth-century Bohemia, when the diffusion and interpretation of Darwin’s teachings were first undertaken, above all by two professors of aesthetics at Prague – Josef Durdík and Otakar Hostinský. Although they somewhat simplified the theory of natural selection, they understood Darwin’s theory to be the arrival of a new paradigm in contrast to contemporary biologists working in the Bohemian Lands. This article presents and compares both aestheticians’ interpretations of Darwinism, (...) mainly their stance on the theory of natural selection, the possibilities of applying this theory to aesthetics and art, as well as their relationship to Darwin’s interpretation of aesthetic phenomena in nature.

Many biologists still believe in a sort of post-Cartesian foundation of reality wherein objects are independent of subjects which cognize them. Recent research in behaviour, cognition, and psychology, however, provides plenty of evidence to the effect that the perception of an object differs depending on the kind of animal observer, and also its personality, hormonal, and sensorial set-up etc. In the following, I argue that exposed surfaces of organisms interact with other organisms’ perception to form semiautonomous relational entities called semantic (...) organs, which participate in biological reality as discrete heritable evolutionary units. The inner dimensions and potentialities of an organism can enter the senses of another living being when effectively expressed on the outer surfaces of the former and meaningfully perceived by the latter. Semantic organs have three basic sources of variability: intrinsic, i.e., genetic, epigenetic, and developmental processes; extrinsic, meaning the biotic and abiotic environmental conditions which affect the developmental generators of intrinsic variability; and perceptual, stemming from differences in the subject-specific interpretation of a SO’s structural basis. Extrinsic and intrinsic sources of variability are, however, just precursors to semantic organs. SOs are relational entities which always come into existence through an act of perception and their actual form depends both on the physical potentialities of the bearer and the species- or group-specific interpretation of the receiver.

This paper offers an explanation of the maj or traditions in the logical treatment of definite descriptions as reactions to paradoxical naive definite descriptiontheory. The explanation closely parallels that of various set theories as reactions to paradoxical naive set theory. Indeed, naive set theory is derivable from naive definite description theory given an appropriate definition of set abstracts in terms of definite descriptions.

Cet essai aborde la question phénoménologique fondamentale de la donation de l’apparaître. L’auteur commence par noter que la distinction husserlienne entre l’apparaître comme vécu (Erscheinen als Erleben) et ce qui apparaît (das Erscheinende) ou phénomène a été critiquée à partir de deux perspectives différentes dont Patočka et Henry sont, respectivement, deux représentants importants. Quoique tous deux critiquent la même distinction husserlienne, l’auteur montre cependant que leurs critiques prennent en réalité des directions opposées. Patočka entend développer une phénoménologie asubjective dans laquelle (...) la donation fondamentale de toute apparence se trouve dans le « se-montrer-soi-même » (Sich-selbst-zeigen) des êtres. Plutôt que dans le domaine de l’auto-donation du vécu de l’expérience (Erleben), cette phénoménologie fonde l’apparence dans la sphère phénoménologique globale du monde. Henry, quant à lui, ne rejette pas le domaine subjectif mais renforce bien plutôt son importance en radicalisant la distinction husserlienne entre l’expérience et le phénomène et en la remplaçant par la différence qu’il établit entre révélation et manifestation. La manifestation suppose toujours la distance et l’intentionnalité. La révélation, en revanche, peut être comprise comme une radicalisation de l’expérience husserlienne, puisqu’elle est un mode d’apparaître qui n’implique pas une forme de pensée (meinen) et d’intentionnalité. Elle est, en tant que telle, exempte de la distance que Henry exclut du domaine d’intériorité où se produit la révélation. L’auteur discute alors ce contraste entre Patočka et Henry et montre à quel point l’accent mis sur le monde dans l’explication de la donation donnée par le premier diffère de la relation à soi subjective qui est au cœur de l’explication de la donation offerte par le second.

Public debate on acceptable farm animal husbandry suffers from a confusion of tongues. To clarify positions of various stakeholder groups in their joint search for acceptable solutions, the concept of animal welfare was split up into three notions: no suffering, respect for intrinsic value, and non-appalling appearance of animals. This strategy was based on the hypothesis that multi-stakeholder solutions should be based on shared values rather than on compromises. The usefulness of such an artificial value distinction strategy was tested in (...) a small series of experiments. The results demonstrate that the chosen concept to distinguish between values is effective in a stakeholder context. Farmers’ views on doing good to animals appeared to be largely based on their value to prevent suffering and predominantly focused on the provision of regular care. Their priority for this value is clearly shared with other stakeholders, providing a basis for joint solutions. The concept of intrinsic value does not play a discernable role in farmers’ considerations. Based on the varying views on welfare, it can be inferred that there is a gradual rather than a principal difference between government legislation and farmers’ values, whereas public perception and acceptance of farm practices remains complicated. Distinction between value groups and focusing on a selected notion (such as no suffering) proved to be effective in bringing representatives of stakeholder groups together, but is unlikely to bridge the emotional gap between commercial farm practices and public ideals.

Pojem řádu má své veliké dějiny od předsókratiků až k H. Kringsovi, který v roce 1941 vydává knihu Ordo. U nás se pojmu řádu a řádovosti věnoval po celý život ze­jména brněnský a olomoucký myslitel J. L. Fischer (1894–1973). Idea řádu byla také jedním z pilířů jeho skladebné filosofie, jež měla základní problémy moderní společnosti vyřešit účinněji než marxismus. Současně s „laickým“ Fischerem usilovala v kritických 30. letech dvacátého století o nastolení kýženého řádu vyhraněně katolická skupina sou­středěná kolem tehdy nově (...) založené revue Řád. Oběma pólům šlo sice o podobný cíl (skoncovat s vládou neblahého kapitalismu), ale neporozuměly si pro různost svých věr. Toto osudové neporozumění bychom měli především na univerzitách v Brně a Olomou­ci napravovat využitím odkazu W. C. Smithe, který zásadně rozlišil setrvačnou tradiční víru (belief) a otevřenou víru všech opravdu tvůrčích lidí (faith). Takovou víru měl totiž podle autora také a snad především nový řád usilovně hledající Josef Ludvík Fischer. (shrink)

The basic theory of scientific understanding presented in Sections 1–2 exploits three main ideas.First, that to understand a phenomenonP (for a given agent) is to be able to fitP into the cognitive background corpusC (of the agent).Second, that to fitP intoC is to connectP with parts ofC (via arguments in a very broad sense) such that the unification ofC increases.Third, that the cognitive changes involved in unification can be treated as sequences of shifts of phenomena inC. How the theory fits (...) typical examples of understanding and how it excludes spurious unifications is explained in detail. Section 3 gives a formal description of the structure of cognitive corpuses which contain descriptive as well as inferential components. The theory of unification is then refined in the light of so called puzzling phenomena, to enable important distinctions, such as that between consonant and dissonant understanding. In Section 4, the refined theory is applied to several examples, among them a case study of the development of the atomic model. The final part contains a classification of kinds of understanding and a discussion of the relation between understanding and explanation. (shrink)

Mimicry is often cited as a compelling demonstration of the power of natural selection. By adopting signs of a protected model, mimics usually gain a reproductive advantage by minimising the likelihood of being preyed upon. Yet while natural selection plays a role in the evolution of mimicry, it can be doubted whether it fully explains it. Mimicry is mediated by the emergence of formally analogous patterns between unrelated organisms and by the fact that these patterns are meaningfully perceived as similar. (...) The perception of similarity is always perceiver-dependent. Similarities between for instance colours are psychophysical phenomena, and their existence is conditioned by an intimate interdependence between perceivers and perceptible reality. In this sense, mimicry is by its very nature dualistic. The analogy in form needed to establish a mimicry does not emerge out of the blue. It depends on the ecological context and the morphogenetic potential of a species. In our proposal, we take into account both the developmental generators of formally analogous structures and the perceptual and cognitive processes that lead to the emergence of mimicry. We show that some of the rather controversial and nowadays largely neglected ideas found in non-Anglo-Saxon literature on mimicry deserve closer attention. We suggest that the diversity of mimicry types is due to differences in variational properties of form-generating and perceptual systems among diverse groups of organisms. We also anticipate that processes studied within social psychology and emotion research probably take place, at least in a simplified form, also in non-human animals. Finally, we argue that these meaning-attributive processes underlie the functionality of mimicry. (shrink)
