The most important are research rules which has been used by A. Walicki, and their consequences on his intellectual work as well as some critical remarks. (shrink)

Murray N. Rothbard and Hans-Hermann Hoppe build their libertarian theory of justice on two axioms concerning self-ownership and homesteading, which are bolstered by two key arguments: reductio ad absurdum and performative contradiction. Each of these arguments is designed to demonstrate that libertarianism is the only theory of justice that can be justified. If either of these arguments were valid, it would prove the libertarian claim that the state is an unjust political arrangement. Giving due weight to the importance of the (...) libertarian anarchist claim, this article exposes and criticizes the arguments that substantiate it. (shrink)

RubisCO is Earth's main enzyme responsible for CO2 fixation via carboxylation of ribulose-1,5-bisphosphate into organic matter. Besides the carboxylation reaction, RubisCO also catalyzes the oxygenation of RuBP by O2, which is probably as old as its carboxylation properties. Based on molecular phylogeny, the occurrence of the reactive oxygen species -removing system and kinetic properties of different RubisCO forms, we postulated that RubisCO oxygenase activity appeared in local microoxic areas, yet before the appearance of oxygenic photosynthesis. Here, in reviewing the literature, (...) we present a novel hypothesis: the RubisCO early oxygenase activity hypothesis. This hypothesis may be compared with the exaptation hypothesis, according to which latent RubisCO oxygenase properties emerged later during the oxygenation of the Earth's atmosphere. The reconstruction of ancestral RubisCO forms using ancestral sequence reconstruction techniques, as a promising way for testing of RubisCO early oxygenase activity hypothesis, is presented. RubisCO catalyzes carboxylation and oxygenation of ribulose-1,5-bisphosphate. Carboxylating properties of RubisCO are an ancient way for CO2 fixation into organic matter. However, an evolutionary importance of oxygenase activity of RubisCO remains enigmatic. Here, we formulated RubisCO early oxygenase activity hypothesis. According to this hypothesis, RubisCO oxygenase activity appeared yet before the appearance of oxygenic photosynthesis. (shrink)

Article presents the experience of death from the point of view of the second person in the context of the problems that arise from Epicurus’s famous thesis that as long as we exist, death is not present and when it is present, we do not exist. The epistemo-logical problem is the possibility of experiencing death. We cannot resolve this problem from the point of view of the first or third person. In your death, however, the death of a close friend, (...) of a person emotionally connected with me, I can partly experience my own death. We can resolve some of the other problems in a similar manner: the ontological prob-lem, the axiological problem, the moral problem and the eschatological problem. (shrink)

In the paper, several data reduction techniques for machine learning from big datasets are discussed and evaluated. The discussed approach focuses on combining several techniques including stacking, rotation, and data reduction aimed at improving the performance of the machine classification. Stacking is seen as the technique allowing to take advantage of the multiple classification models. The rotation-based techniques are used to increase the heterogeneity of the stacking ensembles. Data reduction makes it possible to classify instances belonging to big datasets. We (...) propose to use an agent-based population learning algorithm for data reduction in the feature and instance dimensions. For diversification of the classifier ensembles within the rotation also, alternatively, principal component analysis and independent component analysis are used. The research question addressed in the paper is formulated as follows: does the performance of a classifier using the reduced dataset be improved by integrating the data reduction mechanism with the rotation-based technique and the stacking?

Strategic games require reasoning about other people’s and one’s own beliefs or intentions. Although they have clear commonalities with psychological tests of theory of mind, they are not clearly related to theory of mind tests for children between 9 and 10 years of age “Flobbe et al. J Logic Language Inform 17(4):417–442 (2008)”. We studied children’s (5–12 years of age) individual differences in how they played a strategic game by analyzing the strategies that they applied in a zero, first, and (...) second-order reasoning task. For the zero-order task, we found two subgroups with different accuracy levels. For the first-order task, subgroups of children applied different suboptimal strategies or an optimal strategy. For the second-order task only suboptimal strategies were present. Strategy use for all tasks was related to age. The 5- and 6-year old children were additionally tested on theory of mind understanding and executive functioning. Strategy-use in these children was related to working memory, but not to theory of mind after correction for age, verbal ability and general IQ. (shrink)

The paper deals with the ethical-moral dimension of Popper’s critical rationalism, which is the less analyzed aspect of his philosophy. Critical rationalism is not without assumptions. As a life attitude, it is actualized on the basis of one’s moral preferences based rather on assumptions than on critical reasonableness. Critical rationalism does not exclude logical argumentation and reasoning, but the adoption of them is predominantly the result of an individual moral decision and choice, based, paradoxically enough, on an irrational belief in (...) reason. The author considers this attitude to be productive, as it emphasizes individual moral responsibility. Nobody is able to persuade us about the relevance of what we don’t want to adopt and apply. Thus we find ourselves in the sphere of personal morality. (shrink)

Christianization of Polish territories, according to the Western rite, incorporated these lands into the Western European civilization and emerging there political and legal doctrines, which were used in creating Polish political-legal thought. At the time of establishing social bonds and structures of the state, the political elite came into being and the Polish political thought developed. It corresponded with the main political thought and ideas of the West, but the Polish ideas displayed characteristics, necessary for protecting the Polish raison d’etat. (...) Development of political thought, original and particular for Polish conditions, dissimilar from the main European trends, may be a testimony to richness of intellectual and political ideas of past Polish generations. It was this political thought, that allowed the Polish national identity to survive, and caused that the fight for political independence was successful. Many contemporary researchers, including those from Western Europe, see influences of the past political ideas in the contemporary attitudes of Poles. (shrink)

The paper clarifies Havel’s perception of post-democracy through his various writings and speeches, in comparison with the concepts of post-democracy as proposed by C. Crouch, J. Rancière, R. Rorty, S. Wolin, J. Habermas, and Ch. Mouffe. Consequently, Havel’s critique of the then Western parliamentary democracy and the very essence of his notion of post-democracy will be thoroughly illuminated. The historical and intellectual circumstances that shaped his thinking on the topic will be analysed as well. Some misinterpretations of Havel’s thinking that (...) have emerged in the meantime will also be clarified. (shrink)

It is quite popular nowadays to postulate various kinds of unarticulated constituents that have essential bearing on truth conditions of utterances. F. Recanati champions an elaborated version of contextualism according to which one has to distinguish two kinds of unarticulated constituents: those that are articulated at the level of the logical form of a given sentence and those that are truly unarticulated. Recanati offers a theory which explains the manner of incorporating truly unarticulated constituents into the propositions expressed. This theory (...) invokes variadic functions. The present paper shows that variadic functions are unnecessary because no constituents are truly unarticulated in the sense assumed by Recanati. An alternative explanation is offered according to which all propositional constituents are either explicitly or implicitly represented at the syntactic level. (shrink)

In a world increasingly concerned with the human species and its future, Marian Stamp Dawkins argues that we need to rethink some of the fundamental questions regarding animal welfare. How are we justified in projecting human emotions on to animals? What kind of mental lives do they have? What can science tell us about their quality of life?

Narrowly speaking, the correspondence theory of truth is the view that truth is correspondence to a fact -- a view that was advocated by Russell and Moore early in the 20 th century. But the label is usually applied much more broadly to any view explicitly embracing the idea that truth consists in a relation to reality, i.e., that truth is a relational property involving a characteristic relation (to be specified) to some portion of reality (to be specified). During the (...) last 2300 years this basic idea has been expressed in many ways, resulting in a rather extended family of views, theories, and theory sketches. The members of the family employ various concepts for the relevant relation (correspondence, conformity, congruence, agreement, accordance, copying, picturing, signification, representation, reference, satisfaction) and/or various concepts for the relevant portion of reality (facts, states of affairs, situations, events, objects, sequences of objects, sets, properties, tropes). The resulting multiplicity of versions and reformulations of the theory is due to a blend of substantive and terminological differences. (shrink)

This book explores the language and arguments Jacques Derrida uses in his writings, and how this is at the core of his work. Marian Hobson explores the French language in which Derrida's philosophy is written in, and the ways his ideas are organized, to suggest that this has an overriding affect on how his translated work affects our understanding of his thought.

What is animal welfare? Why has it proved so difficult to find a definition that everyone can agree on? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as 'health and animals having what they want', a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we (...) need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare. But, can we really understand what animals want? A consistent theme running through the book is that not only is it possible to establish what animals want, but that this information is vital in helping us to make sense of the long and often confusing list of welfare measures that are now in use such as 'stress' and 'feel good hormones', expressive sounds and gestures, natural behaviour, cognitive bias, and stereotypies. Defining welfare as 'health and what animals want' allows us to distinguish between measures that are simply what an animal does when it is alert, aroused, or active and those measures that genuinely allow us to distinguish between situations the animals themselves see as positive or negative. Sentience (conscious feelings of pleasure, pain, and suffering) is for many people the essence of what is meant by welfare, but studying consciousness is notoriously difficult, particularly in non-human species. These difficulties are discussed in the context of our current - and as yet incomplete - knowledge of human and animal consciousness. Finally, the book highlights some key ideas in the relationship between animal welfare science and animal ethics and shows how closely the well-being of humans is linked to that of other animals. The Science of Animal Welfare is an ideal companion for undergraduate and graduate students taking courses in animal behaviour and welfare, as well as for professional researchers, practitioners and animal welfare consultants. At the same time, it is easily understandable to non-scientists and anyone without prior knowledge but with an interest in animals and the rapidly evolving science of animal welfare. (shrink)

To study animal welfare empirically we need an objective basis for deciding when an animal is suffering. Suffering includes a wide range ofunpleasant emotional states such as fear, boredom, pain, and hunger. Suffering has evolved as a mechanism for avoiding sources ofdanger and threats to fitness. Captive animals often suffer in situations in which they are prevented from doing something that they are highly motivated to do. The an animal is prepared to pay to attain or to escape a situation (...) is an index ofhow the animal about that situation. Withholding conditions or commodities for which an animal shows (i.e., for which it continues to work despite increasing costs) is very likely to cause suffering. In designing environments for animals in zoos, farms, and laboratories, priority should be given to features for which animals show inelastic demand. The care ofanimals can thereby be based on an objective, animal-centered assessment of their needs. (shrink)

The PhD thesis advances a new approach to vagueness as dispersion, comparing it with the main philosophical theories of vagueness in the analytic tradition.

We generalize the Bolzano-Weierstrass theorem on ideal convergence. We show examples of ideals with and without the Bolzano-Weierstrass property, and give characterizations of BW property in terms of submeasures and extendability to a maximal P-ideal. We show applications to Rudin-Keisler and Rudin-Blass orderings of ideals and quotient Boolean algebras. In particular we show that an ideal does not have BW property if and only if its quotient Boolean algebra has a countably splitting family.
