The general aim of this book is to provide an elementary exposition of some basic concepts in terms of which both classical and non-dassicallogirs may be studied and appraised. Although quantificational logic is dealt with briefly in the last chapter, the discussion is chiefly concemed with propo gjtional cakuli. Still, the subject, as it stands today, cannot br covered in one book of reasonable length. Rather than to try to include in the volume as much as possible, I have put (...) emphasis on some selected topics. Even these could not be roverrd completely, but for each topic I have attempted to present a detailed and precise t’Xposition of several basic results including some which are non-trivial. The roots of some of the central ideas in the volume go back to J. Luka siewicz’s seminar on mathematicallogi. (shrink)

In this note I am reflecting on interrelations between three concepts of truth: that employed by Hilbert arguing his formalist view on the nature of mathematics, Freges idea of truth supported by mathematical intuition, and known as Aristotelian correspondence idea of truth concerning any propositions not merely mathematical.

The article examines the concept of anti-irrationalism coined by the members of the Lvov-Warsaw School. The term “anti-irrationalism” comes from Ajdukiewicz, who used it to define the specificity of the School as a whole. For Ajdukiewicz, anti-irrationalism, which values cognition with intersubjective qualities, is contrasted with irrationalism. The article discusses Twardowski’s tripartite division of beliefs into rational, “irrational,” and “non-rational.” Against this background, the article explores Dąmbska’s view on irrationalism, which is divided by her into several subcategories.Finally, the author considers (...) the question of anti-irrationalism as a metaphilosophical standpoint in the context of the question of a worldview.

Cooperation between doctors of various specialties and other medical specialists is the standard of care in the treatment of patients. Due to the variety of diseases and the dynamic development of medicine in general, it is difficult to be an expert in every field and know all the recommended treatments. An example of such cooperation is the joint treatment of patients with the problem of ingrown toenails. The article contains an analysis of patients who received treatment in a doctor’s office (...) in cooperation with podiatrists. A conservative approach towards the treatment of this condition sees the patient being initially diagnosed and treated by a podiatrist and then later, if necessary, being referred to a doctor for surgical treatment. The exchange of experiences and information on patients treated by interdisciplinary teams allows doctors and podiatrists to find the best possible treatment and improve the quality of life of patients. The follow-up of patients after surgery can be performed later in podiatry offices. Owing to modern electronic communication, it is possible for a doctor to constantly monitor the patient’s condition without the need for direct visits to the doctor’s office. (shrink)

Like many libertarian thinkers, Simpson assumes that the minimal state is culturally neutral. This is false. Libertarianism is a theory opposed to hierarchy at the state level. As such, it also undermines the grounds for hierarchy at the community level. Since communities require some form of hierarchy not only to exist but to generate meaningful culture, libertarianism is inherently nonneutral towards culture. From this it follows that Simpson's idea of a minimal state overseeing various nonliberal communities cannot be realized within (...) the libertarian framework. In its place, I defend republicanism, which makes no pretensions toward cultural neutrality. (shrink)

In a departure from traditional Western political theory that is reminiscent of left?wing anarchism, contemporary libertarianism rejects the necessity of making political choices based on a value hierarchy, instead claiming that it is possible for all individuals to pursue their divergent values simultaneously?as long as each respects the equal rights of others to do the same. The caveat, however, hides a conflict of loyalties that would plague a libertarian society: on the one hand are the particular loyalties of one's preferred (...) Utopian community; on the other hand, loyalty to the larger ?framework for utopias?; within which one's utopia exists. The second loyalty implies a value relativism incompatible with the first one, meaning either that loyalty to the libertarian framework will undermine the utopias within it, or that the particular values of the utopias will destabilize the libertarian framework. The durability of a libertarian society, then, requires a mentality best characterized as nihilistic. In this, libertarianism differs from liberalism but is surprisingly similar to the cultural diversity movement. The thesis is illustrated by examining John Gray's attempt to eschew both a hierarchy of values and moral relativism. (shrink)

The difference between what's possible and what's not is a construct of the human mind, a matter of perspective, and it's one that can be changed. Working Wonders explains the fundamentals that shape the mind: how it builds walls to protect itself and how a person can tear those walls down to tackle challenges that would have previously been discounted as unrealistic. This volume shares case studies featuring people making the impossible a reality and, in doing so, changing the world (...) for the better. On a deeper level and yet still using non-technical language, the book identifies possible neurological and psychosocial mechanisms that limit the brain, and techniques that may open it up to exploring the seemingly unachievable. Praszkier also introduces the concept of 'possibilitivity', a personality trait that reflects the propensity to perceive insurmountable challenges as doable, and concludes by presenting a portfolio of 'Do It Yourself' techniques.

Traditional theism (in Christianity, Judaism and Islam) understands God as possessing certain attributes including omnipotence. God is omnipotent in the sense that God possesses unlimited (maximal) power. For some classical philosophers and theologians (PetrusDamiani, René Descartes) God’s omnipotence requires his being able to do absolutely anything, including the logically impossible. But in Thomas Aquinas’ opinion, to do what is logically impossible is not an act of power but is self-contradictory action. For Aquinas, a logically impossible action is not an action. (...) The contemporary British philosopher of religion, Richard Swinburne, considers omnipotence from an analytic perspective and, partially,within Aquinas’ tradition. For Swinburne, omnipotence includes the power to perform only logically possible and consistent tasks. In this paper, I discuss systematically (§§ 3-6) the philosophical and logical problems of omnipotence and the relation between God and logic from the perspective of Jan Łukasiewicz’s logical investigations. Keywords: Omnipotence, God, logic, rationality, Richard Swinburne, Jan Łukasiewicz. (shrink)

In this paper I discuss the problem of rationality of beliefs. The standard model of rationality proposes three conditions: 1) proper articulation, 2) respecting the requirements of logic , 3) sufficient justification. The second condition is usually understood as two requirements: one concerning consistency, the other suitable deductive abilities. This idea of logical rationality is idealised and not used in practice. For this reason the idealized conception should be reformulated. The conception of minimal logical rationality requires the fulfilment of some (...) conditions but it would not presuppose logical omniscience. (shrink)

Relations between individual traits and frequency of causing accidents have been analyzed. On the basis of results from 465 women and 277 men it has been found that the causing of accidents correlates with risk propensity and with risk taking influenced by self-destructive motivation. Persons often causing accidents are also absent minded to a greater degree, and experience depressive moods more frequently than persons rarely involved in accidents.

This paper was presented at the Annual Conference of the Australian Association for Logic, Melbourne, November, 1979. The present note being complementary to [1], I shall only brie y recall the key notions to be exploited here, and for more details the reader is advised to consult [1]. By a propositional logic we mean a couple , where L is a propo- sitional language and C a structural consequence de- ned on L. A couple W = is said to be (...) a referential matrix for the language L i there exists a non-empty set T such that the following two conditions are satised: i. A is an abstract algebra similar to L, whose all elements belong to f0; 1g T , i.e. they are mappings from T into the two-element set f0; 1g. ii. D = ffa 2 A : a = 1g : t 2 Tg. (shrink)

In Society as a Department Store Ryszard Legutko wrestles with the emancipatory ideology promulgated by postmodernists, libertarians, and liberal thinkers. Legutko argues that modern Western liberals have embraced a revolutionary ethic; they have turned their backs on their own cultural heritage, and used its political and ideological apparatus to destroy classical metaphysics and epistemology. The book considers the paradoxical implications of this state of affairs for Eastern European intellectuals arguing that, with the triumph of liberalism over communism, these intellectuals (...) feel compelled to digest an ideology that shares many elements with the oppressive system from which they just liberated themselves. Based on hubris rather than genuine humane concerns, Legutko mourns not simply the loss of faith in classical Western culture, but the way in which that loss is becoming a central point of identity.

This article explains how people synchronize their thoughts through empathetic relationships and points out the elementary neuronal mechanisms orchestrating this process. The many dimensions of empathy are discussed, as is the manner by which empathy affects health and disorders. A case study of teaching children empathy, with positive results, is presented. Mirror neurons, the recently discovered mechanism underlying empathy, are characterized, followed by a theory of brain-to-brain coupling. This neuro-tuning, seen as a kind of synchronization between brains and between individuals, (...) takes various forms, including frequency aspects of language use and the understanding that develops regardless of the difference in spoken tongues. Going beyond individual-to-individual empathy and SYNC, the article explores the phenomenon of synchronization in groups and points out how synchronization increases group cooperation and performance.

In Poland, the practical difficulties encountered in the struggle to create a capitalist society are leading many Hayekian liberals to the realization that social factors crucial to the creation and stability of such a society are invisible within the classical liberal intellectual horizon and are undermined by its ethic of egalitarian individualism. Therefore, paradoxically, a major step forward in the creation of a liberal society has been the abandonment of significant elements of liberal ideology in favor of civic republican and (...) neoconservative ideas.

Przypadek i Opatrzność Boża. Uwagi metodologiczne z Pascalem w dalszym tle Wedle autora tego artykułu, analityczna filozofia religii nie powinna być zamknięta dla innych sfer kultury i ignorować lub lekceważyć osiągnięć innych, zarówno przeszłych, jak i współczesnych prądów filozoficznych. Filozof analityczny, w tym analityczny filozof religii, może zatem szukać inspiracji również poza sferą filozofii analitycznej. Jednocześnie nie oznacza to, że filozof analityczny ma lekceważyć nauki przyrodnicze lub nie troszczyć się o precyzję języka i właściwe argumenty. Troska o precyzję językową i (...) stosowanie odpowiedniej argumentacji ma kluczowe znaczenie dla tożsamości filozofii analitycznej. Ten artykuł, biorąc pod uwagę wskazane nastawienie metafilozoficzne, poświęcony jest krytycznej dyskusji na temat niektórych problemów poruszonych przez prof. Dariusza Łukasiewicza, w jego wybitnej pracy w dziedzinie filozofii religii, noszącej tytuł Opatrzność Boża, wolność, przypadek. Studium z analitycznej filozofii religii. (shrink)
