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)

The mystical experiences of the ṛṣis , the spiritual giants of the early Vedic times, led to the creation of the Vedic hymns and eventually to the formation of the whole elaborate structure of the Vedic religion, as upheld by the Indian priesthood. But there were obviously others who pursued mystical experiences without themselves engaging, like the ancient ṛṣis , in attempts to transmit their experiences through mythological poetry and religious leadership. They adopted mystical ecstasy as their way of life. (...) Mysticism as a conscious way of life is, in India, called Yoga. Being outside the trend of Vedic mythological creativity and the Brāhmanic religious orthodoxy, the Yogis of Vedic times left little evidence of their existence, practices and achievements. And such evidence as has survived in the Vedas is scanty and indirect. (shrink)

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)

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 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.

The article discusses several possible interpretations of Socrates’ suggestion that we cannot “understand the nature of soul satisfactorily without understanding the nature of the whole” (Phaedrus 270c1–2). Against those who take the “whole” implied here for the cosmic whole, it argues that nothing in the Phaedrus justifies this interpretation. In the light of both Socrates’ conception of rhetoric in this dialogue and his image of the tripartite soul in the palinode, the “whole” whose knowledge is prerequisite to knowing the soul’s (...) nature is better understood as either the whole of the composed soul or the whole soul-body compound. The real problem of the passage, the article concludes, is that we lack any clear criteria that would enable us to decide between these two readings. At the same time, the dramatic progress of the dialogue makes it possible to argue that Phaedrus briefly misunderstands Socrates’ meaning by reading in it some cosmological connotations. This possibility notwithstanding, it is more likely that, from the perspective of the tripartite soul and its actions and passions, “the whole soul-body compound” and “the whole soul” are two equally defensible solutions to the puzzle.

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.

The COVID-19 pandemic has highlighted the difficult task of balancing access to misinformation with respect for patient decision-making. Due to its innate antagonism, the paradigm of “physician paternalism” versus “patient autonomy” may not adequately capture the clinical relationship. The authors hypothesized that most patients would, in fact, prefer significant physician input as opposed to unopinionated information when making medical decisions. There is a lack of empirical data corroborating this in the United States. To that end, a survey was distributed to (...) 650 individuals through Amazon Mechanical Turk, of which 499 responses met pre-determined quality criteria. Most respondents believed their doctor's insight would be better than their own if injured or gravely ill. When asked to affirm preferences separately, a significantly higher proportion of respondents preferred guidance from their doctor when making medical decisions compared to being presented with unopinionated information ( p < 0.001). Encouragingly, 93.1% believed that the doctor's primary goal was their health. When asked directly to compare physician guidance to unopinionated information, 69.1% respondents stated they would prefer physician guidance. We found a consistent association between educational/economic background and affirmative responses ( p < 0.001), suggesting particular attention should be paid to patients that are disadvantaged with respect to these demographic factors. The belief in a shared goal, and a consistent preference for physician input, suggests that patients endorse a more collaborative view of the clinical dynamic than is suggested by the paternalism-autonomy paradigm. This pilot study suggests physicians should not be afraid to communicate conviction with regard to treatment decisions. (shrink)

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

Le rapport issu de la commission Bouchard-Taylor qualifie la laïcité qui s’est implantée au Québec comme étant « plus libérale que républicaine », car elle permet à tous les citoyens « d’exprimer leurs convictions religieuses dans la mesure où cette expression n’entrave pas les droits et libertés d’autrui ». Les régimes républicains y sont présentés comme ceux qui refoulent les différences ethnoculturelles, « en les laissant en marge », tandis que le multiculturalisme accorderait une place prioritaire à la diversité. Dans (...) cet essai, je présente la relation entre le républicanisme et le multiculturalisme sous un éclairage différent. (shrink)

Text se zaměřuje na přijetí a vnímání darwinismu v českých zemích v 19. století, kdy bylo šíření a interpretace Darwinova učení paradoxně spjato s dvěma profesory estetiky z Karlo-Ferdinandovy univerzity v Praze, Josefem Durdíkem a Otakarem Hostinským. Ačkoliv poněkud zjednodušovali teorii přírodního výběru, Darwinovu teorii chápali jako příchod nového paradigmatu. Tento text představuje a srovnává interpretaci darwinismu u obou estetiků, zejména jejich stanoviska k teorii přírodního výběru, možnostem aplikace této teorie v estetice a teorii umění, a také jejich vztah k (...) Darwinově výkladu estetických jevů v přírodě. Jako dodatek následuje krátké vyzdvižení Darwinova učení v textech dalších českých estetiků. (shrink)

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.

It is therefore most appropriate that Yoga and Indian philosophy be given equal attention both in the context of academic research and in the framework of ...
