  1. Once More on Analytic Vs. Synthetic.Pavel Materna - 2007 - Logic and Logical Philosophy 16 (1):3-43.
    The boundary between analytic and synthetic sentences is well definable. Quine’s attempt to make it vague is based on a misunderstanding: instead of freeing semantics from shortcomings found, e.g. in Carnap’s work, Quine actually rejects semantics of natural language and replaces it by behavioristically articulated pragmatics. Semantics of natural language as a logical analysis is however possible and it can justify hard and fast lines between analyticity and syntheticity.

  2. The Notion of Problem, Intuitionism and Partiality.Pavel Materna - 2008 - Logic and Logical Philosophy 17 (4):287-303.
    Problems are defined as abstract procedures. An explication of procedures as used in Transparent Intensional Logic and called constructions is presented and the subclass of constructions called concepts is defined. Concepts as closed constructions modulo α- and η-conversion can be associated with meaningful expressions of a natural or professional language in harmony with Church’s conception. Thus every meaningful expression expresses a concept. Since every problem can be unambiguously determined by a concept we can state that every problem is a concept (...)

    Are Wooden Tables Necessarily Wooden?: Intensional Essentialism Versus Metaphysical Modality.Bjørn Jespersen & Pavel Materna - 2002 - Acta Analytica 17 (1):115-150.
    This paper defendsintensional essentialism: a property (intensional entity) is not essential relative to an individual (extensional entity), but relative to other properties (or intensional entities). Consequently, an individual can have a property only accidentally, but in virtue of having that property the individual has of necessity other properties. Intensional essentialism is opposed to various aspects of the Kripkean notion of metaphysical modality, eg, varying domains, existence as a property of individuals, and its category of properties which are both empirical and (...)

  6. Can Concepts Be Defined in Terms of Sets?Marie Duží & Pavel Materna - 2010 - Logic and Logical Philosophy 19 (3):195-242.
    The goal of this paper is a philosophical explication and logical rectification of the notion of concept. We take into account only those contexts that are relevant from the logical point of view. It means that we are not interested in contexts characteristic of cognitive sciences, particularly of psychology, where concepts are conceived of as some kind of mental objects or representations. After a brief recapitulation of various theories of concept, in particular Frege’s and Church’s ones, we propose our own (...)

    Rules of Existential Quantification Into "Intensional Contexts".Pavel Materna - 1997 - Studia Logica 59 (3):331-343.
    Propositional and notional attitudes are construed as relations (-in-intension) between individuals and constructions (rather than propositrions etc,). The apparatus of transparent intensional logic (Tichy) is applied to derive two rules that make it possible to export existential quantifiers without conceiving attitudes as relations to expressions (sententialism).

    Is Transparent Intensional Logic a Non-Classical Logic?Pavel Materna - 2014 - Logic and Logical Philosophy 23 (1):47-55.
    It is shown that: classicality is connected with various criteria some of which are fulfilled by TIL while some other are not; some more general characteristic of classicality connects it with philosophical realism whereas anti-realism is connected with non-classical logics; TIL is highly expressive due to its hyperintensionality, which makes it possible to handle procedures as objects sui generis. Thus TIL is classical in obeying principles of realism and non-classical in transcending some principles taught by textbooks of classical logic.

    Equivalence of Problems (An Attempt at an Explication of Problem).Pavel Materna - 2013 - Axiomathes 23 (4):617-631.
    On the one hand, Pavel Tichý has shown in his Transparent Intensional Logic (TIL) that the best way of explicating meaning of the expressions of a natural language consists in identification of meanings with abstract procedures. TIL explicates objective abstract procedures as so-called constructions. Constructions that do not contain free variables and are in a well-defined sense ´normalized´ are called concepts in TIL. On the second hand, Kolmogorov in (Mathematische Zeitschrift 35: 58–65, 1932) formulated a theory of problems, using NL (...)

    The so-Called Myth of Museum.Pavel Materna - 2004 - Organon F: Medzinárodný Časopis Pre Analytickú Filozofiu 11 (3):229-242.
    Quine claims that a) considering meaning as a separate object leads to mentalism and b) to overcome mentalism we have to accept an empirical analysis. The paper shows that a) is wrong and not accepting mentalism we can apply a logical, i.e., not empirical approach.

    Mathematical and Empirical Concepts.Pavel Materna - 2012 - In James Maclaurin (ed.), Rationis Defensor.
    Buzaglo (as well as Manders (J Philos LXXXVI(10):553–562, 1989)) shows the way in which it is rational even for a realist to consider ‘development of concepts’, and documents the theory by numerous examples from the area of mathematics. A natural question arises: in which way can the phenomenon of expanding mathematical concepts influence empirical concepts? But at the same time a more general question can be formulated: in which way do the mathematical concepts influence empirical concepts? What I want to (...)

    Denotation and Reference.Pavel Materna - 2010 - Organon F: Medzinárodný Časopis Pre Analytickú Filozofiu 17 (1):3-20.
    The terms denotation and reference are commonly used as synonyms. A more fine-grained analysis of natural language as offered by TIL shows that we can distinguish these terms in the case of empirical expressions. The latter are shown to denote non-trivial intensions while their reference is the value of these intensions in the actual world.

    Question-Like and Non-Question-Like Imperative Sentences.Pavel Materna - 1981 - Linguistics and Philosophy 4 (3):393 - 404.
    There is a distinctive kind of command, namely commands to answer specific questions. An imperative sentence denoting such a command has an interrogative sentence corresponding to it-a sentence denoting the respective question. LetImp, Int, andQ be such an imperative sentence, the interrogative sentence corresponding to it, and the question denoted by the interrogative sentence, respectively. LetQ be an empirical question, i. e., and ((ητ)ω)-object. LetP be an ((ητ)ω)-construction constructingQ. Then the analysis ofImp has the form (QL).LetQ be an analytical question, (...)

    If concepts are explicated as abstract procedures, then we can easily show that each empirical concept is a not an effective procedure. Some, but not all empirical concepts are shown to be of a special kind: they cannot in principle guarantee that the object they identify satisfies the intended conditions.

    In the paper we offer a logical explication of the frequently used, but rather vague, notion of point of view. We show that the concept of point of view prevents certain paradoxes from arising. A point of view is a means of partial characterisation of something. Thus nothing is a P and at the same time a non-P, because it is a P only relative to some point of view and a non-P from another point of view. But there is (...)

    Are Concepts A Priori?Pavel Materna - 2005 - In L. Behounek & M. Bilkova (eds.), The Logica Yearbook 2004. Praha: Filosofia.
    In [Laurence, Margolis 2003] the authors try - within their polemics against F.Jackson’s views in [Jackson 1998] - to decide the question whether concepts are a priori (in their formulation “to be defined a priori”). Their discussion suffers - as a number of similar articles - from a typical drawback: some problem whose solution requires an exact notion of concept is handled as if the latter were quite clear. The consequence of this ‘conceptual laxity’ is that a) the topic of (...)

    Concepts as Hyperintensional Objects.Pavel Materna - 2014 - Logic and Logical Philosophy (2):133-170.
    The author defends the view that the notion of concept, if used in the logical tradition, should be explicated procedurally . He argues that Tichý’s Transparent Intensional Logic is an apt tool for such an explication and derives the respective definition. Some consequences of this definition concern the notions of emptiness, simple concepts, empirical concepts and algorithmic concepts.

    The paper is based on transparent intensional logic. A sentence denotes a proposition and expresses a construction in the sense of Tichý´s definition . ‘Belief sentences’ refer to an attitude of some individual to the sense of the dependent clause, i.e., to the respective construction, which eliminates such problems as ‘paradox of omniscience’. In the case of empirical dependent clauses we can observe that at least besides this relation to a construction one can define a relation of the subject to (...)

    The purpose of this paper can be described as follows. The contemporary philosophical logic cannot work without using some terms well-known from mathematics and logic. Among such terms that play an important role in logical and philosophical analyses of language, meaning and the like we can find function, procedure and construction. One problem is that various authors use these terms in various ways, another problem consists in the well-known fact that many philosophers do not have any idea of what those (...)

    Horwich's Conception of Meanings: How to Change His "Deflationary View" Into a Non-Trivial Conception.Pavel Materna - unknown
    A critical comment to Horwich's deflationary theory of meaning: the deflationary view ignores the fact that the way the subexpressions of an expression are combined is language dependent unlike meaning, which is in a sense 'international'; the link between the grammatical structure and the respective construction is not as direct and simple as it would follow from Horwich's conception.
