It is shown that both classical and intuitionistic propositional logics of an associative binary modality are undecidable. The proof is based on the deduction theorem for these logics.

This is a new edition of the manual published in 1974 and 1984. Compared with those earlier editions it is revised, enlarged and more precise in its argumentation. In its beginnings the manual aimed at meeting the didactic needs to present students of the Faculty of Christian Philosophy at the ATK a complete handling of Christian ethics. The author, who wrote his manual in difficult times of communist ideology, decided to include in one work, besides a positive exposition of Christian (...) ethics, a critical discussion with other ethical systems as well as his own explicit theory on Augustinian and Thomistic ethics, which he endeavoured to develop. Thus the work interlocked the didactic objectives and the process of growth and justification of the Author's views, Krakow 2001, p. 308). (shrink)

It is shown that the expressive power of second-order propositional modal logic whose modalities are S4.2 or weaker is the same as that of second-order predicate logic.

As it is broadly accepted, typical uses of demonstratives are accompanied by demonstrations. The concept of demonstration, however, manifests the action–product ambiguity analogous to that visible in the opposition between jumping and the resulting jump, talking and the resulting talk or crying and the resulting cry. It is also a heterogeneous concept that enables demonstrations to vary significantly. The present paper discusses action–product ambiguity as applied to demonstrations as well as the heterogeneity of the latter. An account that acknowledges ambiguity (...) and heterogeneity of demonstrations is sketched in the paper. It is argued that it has a rich explanatory and descriptive potential. (shrink)

The British philosopher Michael Dummett (1925–2011) not only had a massive influence on the development of analytical philosophy within the philosophy of language, philosophy of mathematics, and metaphysics, but also contributed significantly to historical and metaphilosophical debates about the nature of this philosophical movement and its proper account. He proposed to define analytical philosophy as philosophy whose aim is the analysis of the structure of thought by way of the analysis of language. Hence, it is philosophy the gist of which (...) is the linguistic turn. A number of critics of this proposal (including Barry Smith, Peter Hylton, and Hans-Johann Glock) emphasised that Dummett’s proposal captures merely some features of this diversified and multifaceted philosophical tradition, and is far from being historically adequate.

Argues that the key distinction between human and nonhuman social cognition consists in our complex, diverse and flexible capacities to shape each other's minds in ways that make them easier to interpret.

The article presents two concepts of indexicality. The first, more standard and narrow, identifies indexicality with systematic (meaning controlled) context-sensitivity. The second, broader (derived from the work of Jerzy Pelc), conceives indexicality in terms of the potential variability of the general semiotic characteristics expressions (with respect to the context of use). The text introduces the concept of a pragmatic matrix that serves for a schematic representation of contextual variation. I also recapitulate briefly the views of Jerzy Pelc on the meaning (...) (manner of use) and use of expressions, and briefly indicate its relationship approaches with contemporary debates around contextualism and status of non-sentential speech acts. Finally, the relationship between the broader notion of indexicality and the directival theory of meaning is analyzed. (shrink)

The article rejects various attempts to negate the subjectivity of human embryo, formulated among others in the Polish debate entitled 'Stem cells - life for life?' and organised by the Ministry of Scientific Research and Information Technology in 2003 and 2004. The Author thinks that the proposal to treat a human embryo as a deceased donor of organs, is wrong both in the field of embryology and philosophical anthropology. It is also wrong to question the subjectivity of human embryo using (...) various criteria of growth (developed nervous system, brain, consciousness, participation in the life of society and looking after one's own interests). For these criteria do not define humanity but describe human being in various phases of expressions of his/her human nature. That is why it is not acceptable to make the right to life conditional on the stage and degree of the actualization of humanity. Furthermore, one cannot justify the deprivation of the subjectivity of human embryo because of medical progress and the so-called good of humankind. The acceleration of progress cannot be done at the cost of life of some group of human beings. (shrink)

Maximilian de Gaynesford has argued against the standard view that the reference of the first-person pronoun ‘I’ is determined by a rule linking the referent to some feature of the context of use. In this paper, we argue that de Gaynesford's arguments are inconclusive. Our main aim, however, is to formulate a novel version of the reference rule for ‘I’. We argue that this version can deal with several problematic cases. Our strategy involves analysing the so-called agent of the context (...) as the person responsible for a particular speech act. From this analysis, we exclude a particular class of uses of ‘I’, uses that we believe are best understood as demonstrative. (shrink)

The bioethics of four principles, named as principlism, began in 1979 with the work of Principles of Biomedical Ethics by Tom Beauchamp and James F. Childress and has been widely criticized since the 80s. In recent years four rival approaches towards principlism have been specified in this critique. These include: a) impartial rule theory, developed by K. Danner Clouser; b) casuistry, represented by Albert Jensen, and c) virtue ethics, developed by Edmund D. Pellegrino. The critique of principlism presented by K. (...) Danner Clouser, Bernard Gert was not only defended by T. Beauchamp and J.F. Childress themselves, but also by others, including B. Andrew Lustig, David DeGrazia, and Henry Richardson. The discussion has not weakened but continued till the present time. It was presented extensively in the June issue of The Journal of Medicine and Philosophy. We want to join the discussion from the position of personalistic bioethics. (shrink)

There are three working theses formulated and proved in the paper. First, business ethics as a science not wishful thinking, encounters the following, impossible to overcome, difficulties: Lack of a precise definition of business ethics, Ethical relativism, Strong competition on national, international, and global market, Shareholders’ interests vs. social responsibility of a company, Objective (based on scientific laws) limitations of business ethics, Ethical codes vs. the rules of a company, labour and employment legislation. Second, the author claims that a company (...) cannot be treated as an ethical education institution. This kind of education should begin in a family, kindergartens, and schools. The issues of business ethics should be included into ethical education in above mentioned places. (e.g. negotiation, to keep one’s promise, to keep on schedule etc.) Third, the issue of business ethics (ethical codes) should not be restricted to a company only. It should be put into the context of sector, national, multinational, and global market. (shrink)
