Palmer's attempt to dust off Locke's construct of “inverted spectrum” is discussed here to examine its plausibility. Perceptual inversion could be fulfilled by adopting the notion of “inverted trichromacy” rather than by the proposed existence of “red-green reversed trichromats.” Although the former alternative conforms to a hypothetical world of vampires, it fails to conform to the realities of genetics and neuroscience.

The filling-in process proposed as a cover up for the existence of the blind spot has some conceptual similarities to blindsight. The perceptual operation of a hypothetical mechanism responsible for filling in represents a logical paradox. The apparent indeterminacy of the percept in the optic-disc region can be tested experimentally by viewing the grating test pattern below.

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.

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)

Although worship of the relics of the Buddha — and its corollary, st?pa worship — is a widespread feature of Buddhist devotional practice among both lay Buddhists and monks, there is in some quarters a view that, while recommended to lay followers, it is forbidden to monks. This controversy started very early after the Buddha’s parinibb?na and has reverberated throughout the centuries till the present time. Its source is in the Mah?parinibb?na Sutta, and it stems from the ambiguity in the (...) meaning of the compound sar?ra-p?j? in the Buddha’s reply to?nanda’s two questions concerning the actions to be taken after the Master’s death with respect to his body. The resolution of the controversy depends on a correct understanding of the nature of the Buddha’s replies to the two questions. This paper analyses the relevant passages of the sutta and the way they have been translated, correctly or incorrectly, into Western languages and into Chinese, and finally arrives at a solution derived entirely from within the text of the Mah?parinibb?na Sutta itself.

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.

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)

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