On the Denotation of Propositions

The paper is devoted to the history of considerations on the denotation of propositions, or on that which is denoted, or described by propositions. In the first part of the paper, aside to the views of ancient authors (Plato, Aristotle, Stoics) concerning this issue, the debate about the existence and nature of the denotation of propositions has been presented. It was alive especially in the later scholastic philosophy (two objectivistic standpoints – among others – Gregory of Rimini, and one subjectivistic). The second part of the paper discusses the position of modern and contemporary authors, i.e. two ways with which the question of the denotation of propositions was reconstructed in the 19th century, the so-called Brentano’s schools (Twardowski, Meinong), Frege’s thought and his followers. The texts of many authors have been analysed in order to present (and compare) all the more important views in the question of the denotation of propositions, starting from antiquity until the contemporary times.

Many Values and Epistemic Concepts

The paper presents several attempts to express intuition concerning the understanding of knowledge and conviction by means of the conceptual apparatus of many-valued logic. J. Łoś’s pioneer system has been presented here, the system constructed by Ngoc Duc Ho, in which the internal logic in this system is used by the knowing subject as the three-valued logic of Łukasiewicz and the third logical value is understood as “unjustified”, and the four-valued system of N. Belnap, the system that allows for the occurrence of propositions which are evaluated both as true and false.

Time Arrow and Some Interpretations of Quantum Mechanics
view |
rights & permissions
| cited by
In the paper I discuss some premises of “quantum mechanics” with regard to the thesis that the time arrow does (not) exist. In this context I consider above all the famous Einstein-Podolsky-Rosen’s experiment (EPR-experiment). I also indicate Schrödinger’s interpretation of wave function “symmetrical” towards time (nomological isotropy) and the peculiar understanding of the pair particle-antiparticle, assuming that the direction of time can be reversed. Eventually, I discuss the issue of measurement in quantum mechanics with which the existence of time arrow (anisotropy) is often linked. If it comes to the interpretations of quantum mechanics, from the point of which I consider the issues in question, then in principle I limit myself to two: the so-called Copenhagen interpretation and David Bohm’s conception of “hidden parameters.” I arrive at a conclusion that the premises of quantum mechanics that are at issue here cannot be sufficient grounds for a conclusive recognition of the reversibility (non--existence) of time arrow.

Empirical Modes of Accepting Propositions

The paper brings a critical analysis of the assumptions on which K. Ajdukiewicz (1934) based his considerations concerning the theory of meaning and proposes to look at these problems from a new research perspective. The considerations sought to analyse the modes of accepting propositions which call for a contact with empirical reality, therefore to apply some empirical procedures (observations, tests, experiments).

Values in the Perspective of Konrad Lorenz’s Evolutionary Epistemology
view |
rights & permissions
| cited by
The article presents Konrad Zacharias Lorenz’s views concerning man’s axiological space. According to Lorenz the origin of the cognitive apparatus is defined by the need to maintain orientation in the world. The apparatus is determined (ambiguously) by the biological and cultural factors. Also tendencies to accept a given type of values are dependent on inborn instincts. The harmony of mutual coexistence of biological and cultural norms is a manifestation of a ‘healthy functioning of the world of values’. In recognizing values an important role is attributed to emotions. The specificity of the act of valuation results from its subjectivity outside a direct control of acts of consciousness.

Alvin Plantinga’s Evolution Argument against Naturalism
abstract |
view |
rights & permissions
| cited by
In the article the proposition is put forward that naturalism connected with evolutionism is an attitude involved in many problems, and the rationality of the naturalist attitude is not credible. The proposition is proven on the basis of the evolution argument against the form of naturalism that assumes that evolution theories are true, which was formulated by Alvin Plantinga. In the article it is shown that the naturalist explanation of human cognitive mechanisms is selfrefuting. The naturalist claims that man’s cognitive system originated by way of evolutionary processes, and the aim of these processes is man’s survival, and not the truth of his beliefs; hence – on the basis of such reasoning – one may doubt if all beliefs are true, including the naturalist one. Hence in the article it is shown that the naturalist’s all beliefs, and among them the belief that ‘God does not exist’, cannot be credible. An indirect aim of the evolution argument against naturalism is also intellectual defense of credibility of the theist image of the world.The starting point of the article is presentation of the argument that half a century earlier was formulated by Clive Staples Lewis. Next the details of Plantinga’s argumentation and controversies connected with it are shown. In the final part of the article the relation between naturalism and theism is discussed. In conclusion it is stated that the naturalist attitude does not attain what is required, so that a naturalist could state that it is the way he thinks; and this is why he is not able to threaten Christian theism.

The Earth as Part of the Universe in Saint Thomas Aquinas’ Cosmology
view |
rights & permissions
| cited by
The present article aims at presenting the place the Earth takes in the universe in Saint Thomas Aquinas’ cosmology. The author of the article is of the opinion that Aquinas’ writings, exceeding Aristotle’s commentary, were a comprehensive attempt at answering the question about the real structure of the universe. In the Dominican scholar’s methodology a creative aspect can be seen of the critical assessment of the knowledge available in those times. Such an attitude facilitated a further development of cosmology and is the basis of the value of Saint Thomas’ considerations. He still remained within the system of a geocentric world, but he prepared the data for building a new model of the universe.

Capabilities or Primary Goods?
view |
rights & permissions
| cited by
The article is an analysis of the discussion between Amartya Sen and John Rawls concerning the dispute about the proper space of justice. According to Rawls, the author of the theory of justice as impartiality, primary goods are the basis for defining the proper space of justice (he understands the space of justice as the space of primary goods). On the other hand, in Sen’s opinion, the basis is constituted by human capabilities (the space of justice as the space of human capabilities). The basic aim of the article is to analyze the charges made by Sen against the theory of justice as impartiality based on the category of primary goods.After having taken into consideration the difference in the perspectives accepted by the two authors with respect to the problem of justice (Sen is oriented to securing the fate of the poor, whereas Rawls, focusing on obtaining an impartial choice of principles of justice, is concerned about nobody having a privileged position), the approach proposed by Sen was assessed as the more convincing one. This approach allows considering all the information concerning a broadly understood human existence (health, income, climatic, social, political conditions, etc.) when defining just social relations.

The Connection between Metaphysics and Epistemology in V. S. Soloviov’s Thought
view |
rights & permissions
| cited by
In the article the assumptions are analyzed of V. S. Soloviov’s (1853-1900) metaphysics presented in his Criticism of Abstract Principles. When forming a metaphysics Soloviov considers and subjects to criticism two theories: Hegel’s extreme (in the Russian philosopher’s term – “abstract”) idealism, and the positivists’ radical empiricism. Soloviov perceives resolution of the difficulties seen in these theories in the conception of the so-called all-unity. According to this conception every being has its ontic foundation in the Absolute, which makes possible an inner connection between all things on the metaphysical and, respectively, epistemological level.In the present study it was found that Soloviov’s metaphysics is based on the following assumptions: (1) the thesis about the possibility of cognizing ‘a thing in itself’; (2) determining a close connection that occurs between the ontological and epistemological order; (3) the conviction that analysis of epistemological conception leads to the ontological ‘truth about the thing’. Acceptance of these propositions is connected with the Russian philosopher’s religious beliefs concerning the existence of an ultimate foundation of reality, and his detailed critical-historical analyses are completely subjected to the aspiration to create a theist metaphysics on the basis of this Absolute principle, that is of God.

rights & permissions
| cited by
The paper presents the stand of Henry Mehlberg on the nature of physical time. This is both an antirelational and relativistic outlook. It deals with the problem of ontological independence and physical reality of time, particularly in the context of discussion between relational and substantival theory of time, and criticism of the positivistic interpretation of relational theory. It outlines some arguments for reality of time, derived from the quantum physics. This conception is a philosophical basis of the causal theory of time, created by Henry Mehlberg.

Teleological Explanation of Irreducible Complexity of the Biochemical Systems
view |
rights & permissions
| cited by
The main purpose of this article is a presentation of one of the subtheories included in the so-called intelligent design theory – a concept of irreducible complexity of the biochemical systems. The concept says that some features of different biochemical structures indicate that they are designed. It is an alternative concept to naturalistic theories of evolution, and especially to the Neo-Darwinian theory of the development of the life forms that is currently the dominating theory in biology. I shortly discuss the logical and empirical point of the concept of irreducible complexity, whereas I give special attention to the most interesting, from the methodological point of view, part of the concept, namely the explanatory point. The explanatory point is concerned with the issue of design detection in natural sciences. I present also a response of the concept’s of irreducible complexity critics, in the form of a variety of proposals of the evolutionary scenarios of the irreducibly complex systems origins. Although some of these scenarios describe material processes that, theoretically, are capable of producing the irreducible complexity, I agree with a criticism of intelligent design theory proponents that a high degree of speculativity of the evolutionary explanations presently does not allow for examination if these explanations correspond to the real history of irreducibly complex systems origins. Because, so far, both the evolutionists and design theorists are developing only general approaches to the issue of irreducible complexity that need further detailed analyses, I recognize that the problem of irreducible complexity of the biochemical systems remains unsolved in the advantage of one of the proposed theories.
