Löb's Theorem in a Set Theoretical Setting

We present a semantic proof of Löb's theorem for theories T containing ZF. Without using the diagonalization lemma, we construct a sentence AUT _T, which says intuitively that the predicate autological with respect to T (i.e. applying to itself in every model of T) is itself autological with respect to T. In effect, the sentence AUT _T states I follow semantically from T. Then we show that this sentence indeed follows from T and therefore is true.     

Some Eighteenth Century Contributions to the Mind–Body Problem (Wolff, Taurellus, Knutzen, Bülfiger and the Pre-Critical Kant)

This work speaks about very special solution of the mind–body problem. This solution based on the so-called Principle of Co-existence stands out as one of the most interesting attempts at solving the mind–body problem. It states that substances can only exert a mutual influence on one another if they have something in common. This does not have to be a common property but rather, a binding relationship. Thus, substances co-exist when they remain bound by a common relationship, for instance, to an external subject. The Principle of Co-existence played an extremely important role in Kant’s philosophy, not only since it provided a framework for solving the mind–body problem, but since it captured the very basis of its existence. The Principle found also reflection in the works of Kant’s successors, such as Fichte, Schelling, Hegel or Feuerbach. It had significant—though often hidden—repercussions on later philosophy of mind. The notion of force and the principle of its operation became key concepts in resolving the mind–body problem. As a result, philosophy of mind concentrated on the search for a principle explaining the occurrence of two complementary types of phenomena. This established a tradition which, to a greater or lesser extent, has survived to our day.     

The Polish Catholic Church’s perception of the processes of EU integration and Europeanisation in the context of traditional norms and values

The Catholic Church has historically played a significant role in the sociocultural and political life of Poland. Its activity was particularly evident and significant during the process of political transformation. Since 1989, however, the sociopolitical conditions have remarkably changed, thereby placing the church in a new, challenging context. Poland’s post-1989 political aspirations (opening to the West in particular) have come to the fore of the public debate, in which the church has actively participated. In this article I aim to analyse the church’s position on the process of EU integration and the Europeanisation of Polish law and culture. The main questions concern the direction of argumentation used by the church’s internal wings and the politicisation of the discourse on the axiological shape of Polish culture and tradition. My analysis embraces the debate surrounding the process of European integration, with special consideration of the church’s internal divisions (between the ‘centre-right’ and ‘radical-right’ in particular) and ideological discrepancies concerning the very idea of integration and the debates on the draft Constitution of the European Union (Constitutional Treaty) and the Charter of Fundamental Rights and Freedoms of the European Union.     

Characteristics of Athletes’ Approach to the Question of Physical Health and Health Behaviors: Do Athletes Lead Healthy Lifestyles?

Athletes are people for whom physical health is a key value. Health promoting behaviors are an integral part of athletes’ success. The aim of this article is to identify health criteria and health-related behaviors among athletes and their determinants in terms of temperament and personality features. The concept of healthy lifestyle as understood by athletes and their most important health criteria were defined. Neuroticism and extraversion correlated with and were significant predictors of health behaviors; there were no significant relationships between health-promoting behaviors and temperament. Four groups of athletes, each characterized by a different approach to health, were identified. These groups were described with respect to various personality and temperamental determinants. Knowledge about the above-mentioned aspects of athletes’ performance can assist sport psychologists in providing athletes with more personalized support.
