Cultuurkritisch essay vanuit de optiek van de anti-psychiatrie.

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)

The essays in this volume are based on addresses presented during a colloquium on free logic, modal logic and related areas held at the University of California at Irvine, in May of 1968. With the single exception of Dagfinn F011esdal, whose revised address is included in a recent issue of Synthese honoring W. V. Quine, all of the speakers at the Irvine colloquium are contributors to this volume. Thanks are due to Professor A. I. Melden, Chairman of the Department of (...) Philosophy at Irvine, for his enthusiastic support of the colloquium, and to Drs. Gordon Brittan and Daniel Dennett for their help in the administration of the colloquium. Finally. I should also like to thank Professor Ralph W. Gerard, Dean of the Graduate Division of the University of California at Irvine, for the financial support which made the colloquium possible.

In his phenomenological works Jan Patočka increasingly referred to movement and lived/physical corporeality. He conceived the concept of the world in terms of the correlation of life with its milieu. In conjunction with Edmund Husserl’s late phenomenology of the lifeworld, he took lived corporeality as his starting point and guiding motif in a way that is parallel to Merleau-Ponty’s work. The article expresses an opinion, that it was also one of the reasons why he kept his distance from Eugen Fink’s (...) philosophical cosmology. And still, it is Patočka’s reference to this cosmological project that has had, and keeps on having, an important impact on the recent reception of his work in France. (shrink)

As our work is ever evolving from agrarian to more service-oriented tasks, the rise of machine learning is the advent of an intelligence that contrasts with the natural intelligence exhibited by humans. Many see the emergence of artificial intelligence (AI) as simply another opportunity for business to exploit. Additionally, as coding becomes the new language of the business world, the challenge of using data and analytics to help foster a new generation of human flourishing lessens with organizations solidifying their protocols (...) for the use of AI. As our work changes, it is vital for business to recognize that being a force for good requires policies, procedures, and programs that will respect and promote human dignity at all levels, even amidst the changes brought by AI initiatives. This person-first philosophy needs to be a critical component of any future strategies business utilizes to uphold the well-being of all stakeholders. (shrink)

This essay lays out the leading principles of the theories of definite descriptions advocated by Frege, Russell, and Hilbert and Bernays, and discusses various difficulties, philosophical and otherwise, with each treatment, fixing especially on the treatment of singular existence claims. Then the leading principles of free (definite) description theory are presented and it is shown how it resolves difficulties confronting the more traditional approaches. Finally, a pair of technical problems in free (definite) description theory are addressed. They help to show (...) the fecundity of this treatment of definite descriptions. (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)

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.

The paper focuses on the relation of the so-called Transparent Intensional Logic and Aristotelian Essentialism. TIL is presented here as an antiessentialist system. I analyse the reasons of TIL´s anti-essentialism, and I see the main reasons in the very conception of possible worlds, which is preferred by TIL, as well as in the ontological status of properties and secondarily in the relation between individuals and properties, as TIL conceives it. I assert that even within the frame of TIL it is (...) possible to formulate a certain version of the Aristotelian Essentialism and I point out the intuitions that are connected with the concept of essence and preserved by the formulated conception, contrary to TIL and other systems of modern logic.

Považujeme Leninovo dílo Materialismus a Empiriokriticismus považujeme za vhodnou pro vyjasnění vlastních názorů a objasnění těchto názorů případným čtenářům ze dvou důvodů. Především proto, že jsou v ní vysvětlovány v elementární formě problémy vědomí (ve vztahu k hmotě); a také problematika poznávání a role lidského myšlení v tomto procesu. Druhým důvodem je zjištění, že valná většina lidí, aniž by to tušila, sdílí Leninovy názory na to, co je to hmota a vědomí, zda může existovat pohyb bez hmoty, na to, jak (...) poznáváme, jakož i na další kategorie a problémy.

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

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.

The independent emergence of similar features in phylogenetically nonallied groups of organisms has usually been explained as the result of similar selection pressures particular to specific environments. This explanation has been more or less helpful in elucidating convergent resemblances among organisms since the times of Darwin. Nevertheless, intensive research has brought new knowledge on the emergence of structural similarity among organisms, especially during the last two decades. We now have manifold evidence of the phenomena of evolutionary re-entries or re-evolution, which (...) happens when a particularcharacter present in one organic taxon also appears in another taxon which does not share an immediate ancestry. This is not the re-appearance of the same character, but rather of a similar one. Here I propose a model of threefold origin of similar phenotypic features in unrelated organisms stemming from intrinsic, extrinsic and semiosic causation. It is suggested that neither externalist nor internalist explanations per se, nor any combination thereof, are sufficient to cover all the manifold instances of character re-evolution. There is also a special group of resemblances that consists of what is originated, shaped, and retained in evolution due to meaning attributed to them by particular organic subjects. These cases cannot be fully understood without inviting a biosemiotic approach. Integrating Uexküll’s theory of meaning with the recent evolutionary developmental perspective could complete our understanding of phenotypic re-evolution. (shrink)

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 authors contend that most contemporary logic textbooks fail the average student because they emphasize the evaluation of arguments over their clarification, assuming that the student already understands what motivations underlie logic.

It is an historical fact that one of Russell's greatest philosophical contributions was to highlight the role that premises about logical form play in ontological arguments. A pair of quotations will introduce his point that great metaphysical systems are often not only based on, but are debased by, the belief that certain statements of philosophical discourse are logically subject-predicate in form.Speaking of Hegel's Absolute Idealism, Russell wrote in Our Knowledge of The Extemal World:Mr. Bradley has worked out a theory according (...) to which, in all judgment, we are ascribing a predicate to Reality as a whole; and this theory is derived from Hegel. Now the traditional logic holds that every proposition ascribes a predicate to a subject, and from this it easily follows that there can be only one subject, the Absolute, for if there were two, the proposition that there were two would not ascribe a predicate to either. Thus Hegel's doctrine, that philosophical propositions must be of the form, “the Absolute is such and such,” depends on the traditional belief in the universality of the subject-predicate form. This belief, being traditionaL scarcely self-conscious, and not supposed to be important, operates underground, and is assumed in arguments which, like the refutation of relations, appear at first sight to e;tablish its truth.
