Jacek Urbaniec: Platonism in the philosophy of mathematics does not necessarily imply that there are links between the temporal physical world and the eternal world of mathematics..

Jacek Filek criticizes the modern “nonethical” ethics. He points out its break with philosophy, lack of self-criticism, inanity, undue and fruitless formalism, and academism. His article makes a general request for the restitution of ethics as the independent and dignified scholarly discipline closely connected with world and life.

The first part of the paper is a reminder of fundamental results connected with the adequacy problem for sentential logics with respect to matrix semantics. One of the main notions associated with the problem, namely that of the degree of complexity of a sentential logic, is elucidated by a couple of examples in the second part of the paper. E.g., it is shown that the minimal logic of Johansson and some of its extensions have degree of complexity 2. This is (...) the first example of an exact estimation of the degree of natural complex logics, i.e. logics whose deducibility relation cannot be represented by a single matrix. The remaining examples of complex logics are more artificial, having been constructed for the purpose of checking some theoretical possibilities. (shrink)

This paper refers to the 700th anniversary of the death of Dante Alighieri in commemoration of which Pope Francis released a special apostolic letter highlighting the genius and significance of the Italian poet. We should praise his genius, the Pope writes, because it is he who was able to express, much better than most of the others, the depth of the mystery of God and His love. The Commedia is the fruit of deep religious inspiration. This is why Francis repeats (...) after Benedict XV – „Dante is our own!” Why is it so? Because there breathes in Alighieri the devotion that we too feel and his faith resonates with ours. Dante’s work continues to be a meaningful and valid exemplar for Christ’s followers. However, in today’s pop culture Dante is mainly seen through his depiction of hell – the artistically described eternal punishment. The truth about hell which Dante made the subject of his narrative does not find acceptance even between Christians. Many people are really outraged and scandalized because hell is for them the symbol of sadism and distorted image of God – a vengeful tyrant who condemns human souls to eternal perdition. But hell is present in the biblical message. The early Church Fathers spoke of hell in their sermons, wrote about it in treatises, disputed the dwelling place of the condemned souls, the position of Satan and other demons, and the imminence of God’s judgement. In this way in the Catholic dogmatic theology consolidated the truth of the reality of hell and eternal punishment. This was also in accord with the views of the prominent medieval theologians. Therefore, why the ancient and well-known truth about hell is rejected today as outrageous and Dante’s vision does not gain recognition? The heart of the matter is the understanding of the idea of justice and atonement. In their denial expressed through the notion of the empty hell and rejection of eternal punishment for angels’ and people’s sins, we have to do with misunderstanding of the significance of human intellect and will. The refusal to accept responsibility for our free choices entails the uninhibited rejection of seriousness of our earthly life. If we believe that our fate, and what is more, out eternal fate – the salvation or damnation – depends on what we were able to do in our lifetime, Dante’s poetic vision strongly illustrates this standpoint. The power of free will is deeply and inalienably present in The Comedy’s stanzas. In the Dante’s poem the essence of hell lies in the ultimate rejection of the goal that man longs to achieve from his very nature – the happiness which is the union with the infinite Good – God, the Creator and the Redeemer of the world. How is it possible? It happens due to the existence of free will which is innate to all people and no one can deprive them of it or minimise it. This rejection of the sublime happiness is the result of human free decision – the condemned did not say to God: “Thy will be done!” but “my will be done!”. The existence of hell becomes the guarantee of human dignity, the evidence that a perfectly Good and Omnipotent God treats the man whom He had created seriously and preserves him for the eternity in the same state in which he wanted to remain in his earthly life.

This paper comments on five problems concerning the transformation of the Polish economy with special emphasis on employee participation and trust. 1) There can be no ethical evaluation or justification of employee participation independent of the goals of the transformation. 2) In Poland this participation is affected by deep distrust towards the whole process of transformation. 3) Privatisation is the topic most often mentioned in this connection. 4) The definition of trust becomes even more crucial when the phenomenon of distrust (...) has to be explained. 5) Institutions can become the substitute of trust.

We prove that no logic (i.e. consequence operation) determined by any class of orthomodular lattices admits the deduction theorem (Theorem 2.7). We extend those results to some broader class of logics determined by ortholattices (Corollary 2.6).

In this paper we present a characterization of hyper-connexivity by means of a relating semantics for Boolean connexive logics. We also show that the minimal Boolean connexive logic is Abelardian, strongly consistent, Kapsner strong and antiparadox. We give an example showing that the minimal Boolean connexive logic is not simplificative. This shows that the minimal Boolean connexive logic is not totally connexive.

In this article we consider linear isomorphisms over the field of rational numbers between the linear spaces ℝ2 and ℝ. We prove that if f is such an isomorphism, then the image by f of the unit disk is a strictly nonmeasurable subset of the real line, which has different properties than classical non-measurable subsets of reals. We shall also consider the question whether all images of bounded measurable subsets of the plane via a such mapping are non-measurable.

An increasing number of drugs removed from the market because of unacceptable toxicity raises concerns regarding preapproval testing of drug safety. In the present paper it is postulated that the non-inferiority type of trial should be abandoned in favor of the superiority trial with active controls and less stringent (p<0.1, both for efficacy and toxicity) statistics. This approach will increase sensitivity of detection of drug-induced adverse effects at the expense of increasing false positive results regarding the difference in efficacy between (...) the tested and reference drug. Such a move will increase the protection of future patients. In addition, the proposed design is far more acceptable from the clinical (e.g. no need to specify the statistically expected “unimportant” number of deaths) and ethical points of view, as well as being favored by the strong incentive of involved parties. In the second part of this paper arguments are presented in favor of the hypothesis that placebo (still used in some superiority trials) does not induce adverse effects. The assertion that placebo may induce adverse effects is probably biased by the nature of the clinical experiment. Such a conclusion is supported by studies indicating that placebo-induced adverse effects are disease — and treatment — specific. The modification of clinical trials according to the proposed changes may increase the trials’ sensitivity at detecting adverse effects of drugs. (shrink)

In 1968 the authors of the so-called Harvard Report, proposed the recognition of an irreversible coma as a new criterion for death. The proposal was accepted by the medical, legal, religious and political circles in spite of the lack of any explanation why the irreversible coma combined with the absence of brainstem reflexes, including the respiratory reflex might be equated to death. Such an explanation was formulated in the President’s Commission Report published in 1981. This document stated, that the brain (...) is the central integrator of the body, therefore the destruction of the brain results in the lack of that integration and the death of the organism. Therefore, according to that document, the so-called “brain dead” patients are really, biologically dead; strictly speaking they are not any more biological organisms but collections of organs and tissues. Their death was masked by the use of the medical equipment, but it was a real, biological death. Thus, the explanation given by the President’s Commission Report constituted a biological rationale for the new concept of death, known as “brain death.” However, after the long discussion, this rationale was refuted because of the evidence given by many medical authorities, that the bodies of the “brain dead” and “brainstem dead” patients are alive. In the context of the discussion about the neurological criteria for death, some authors follow the idea of Plato, that human being is the soul or mind, and the body does not belong to the human essence. Therefore, the loss of consciousness, which may be identified with the mind, constitutes the loss of personhood and may be interpreted as human death. The other group stresses the Aristotelian and Thomistic concept that the body belongs to the essence of every living creature, including human. Therefore, as long as the body is alive, the human being is alive and we cannot call the given patient dead even if he is deeply comatose. Moreover, in spite of the opinions dominating in the mass-media, these patients should be considered not only alive but also may be conscious to some degree and their state can be reversible. Their brains are lacking the electrical functions, but the neuronal tissue is alive and that state is reversible for at least first 48 hours since the onset of coma; this phenomenon is called “global ischemic penumbra” and is responsible for the regularly happening events interpreted as miracles, when some of the “brain dead” or “brainstem dead” patients turn to be alive and come back to normal life. Therefore, the neurological criteria of death are still lacking generally accepted scientific basis and should not be used in medicine and in the legal systems as a basis for diagnosing comatose/having no brainstem reflexes/apneic patients dead.

In this article I introduce a hybrid view of persistence whereby simple objects persist by enduring while composite objects persist by being stage-related. I first show how, by sharing certain features and not others with the standard views of persistence, this hybrid view navigates two metaphysical problems that have been raised against such standard views. I then consider some implications of the view by addressing a couple of worries that may be raised against it. I conclude that this hybrid view (...) provides an attractive theory, one that deserves further investigation in the debate on persistence. (shrink)

We assess Cartwright's models for probabilistic causality, and in particular, her models for EPR-like experiments of quantum mechanics. We show that her models for the EPR are mathematically incorrect and physically implausible. Finally, we argue that her models are not adequate for EPR-phenomena, since they ignore modal and spatiotemporal aspects inherent in their setup.

The paper depicts the philosophical views of F. Bochwic (1799-1856) which are as follows: ontology, anthropology, epistemology, ethics, and education. The world, according to Bochwic, was created by God (creationism) and is divided into two spheres: spiritual and carnal (ontological dualism). The factor that unites them is man. His purpose, as a free creature, is his tendency to perfection. The sources of human knowledge are the following: unreliable senses and reliable conscience (intuitionism). Conscience is the source of our presentiments with (...) regard to: the existence of God, immortality of the soul, God\'s justice, and moral orders obligatory for all people (axiological absolutism): the order to make good and avoid evil, the order to love oneself and the neighbour, and the order to obey one\'s parents and superiors. The philosophical views of Bochwic lay at the grounds of his educational doctrine. According to it, education should instil civil virtues in adolescents and be versatile, balanced, varied, imitative, kind, and permanent. (shrink)

Professor Zenomena Płużek has been acknowledged as one of the pioneers and leading scholars in Poland in both the psychology of religion and pastoral psychology. Referring to her research in the area of psychological and psychospiritual crises, this article addresses the issue of the emptiness experienced during psychotherapy as a “dark night”. The case of one particular patient/client will be analyzed from both psychological and religious perspectives, with the aim of answering the following questions: What do such “dark nights” look (...) like in a clinical context? How should they be conceptualized in clinical terms? How ought they to be dealt with? (shrink)
