Our study explores the folk concept of personal identity in the developmental context. Two hundred and seventeen Czech children participated in an interview study based on a hypothetical scenario about a sudden change in their friend, someone they know, or some other unspecified person. The children were asked to judge to what extent particular changes (from six categories of traits) would change the identity core of their friend or some other person on a seven-point scale. We introduced both positive and (...) negative versions of the changes. Our data suggest that children considered moral traits connected to interpersonal relationships crucial for preserving personal identity. Memory connected to personal experiences also scored highly. On the other hand, a change in physical appearance seemed to have the least important impact on personal identity. Negative changes turned out to have a significantly greater impact than positive changes in all categories, except the physical. Possible effects of scenario and the participants’ age and sex were further explored. We discuss the possible causes of the effect of negative moral change and the role of social dimension in the development of the concept of personal identity. (shrink)

Kolman''s philosophy has been, throughout the major part of his life, distinctly Stalinist. After he had been released from prison and after the 20th Congress of the Communist Party of the U.S.S.R. (1956), he became critical of Stalinist dogmatism in philosophy and politics. Although his philosophic thought underwent some — if only minor — changes, Kolman remained entirely within the framework of Marxist philosophy, retaining its foundations, as contained in the writings of the classics of Marxism — Marx, Engels and (...)

2 Popper's Logical Definition of Verisimilitude. 3 Popper's Probabilistic Definition of Verisimilitude. 4 Conclusion.

We give an exponential lower bound on number of proof-lines in the proof system K of modal logic, i.e., we give an example of K-tautologies ψ₁, ψ₂,... s.t. every K-proof of ψi must have a number of proof-lines exponential in terms of the size of ψi. The result extends, for the same sequence of K-tautologies, to the systems K4, Gödel—Löb's logic, S and S4. We also determine some speed-up relations between different systems of modal logic on formulas of modal-depth one.

In his article "world and essence" ("phil. Rev." 1970, Pages 461-492) plantinga submitted that (a) individuals have essences and (b) the essence of an individual is a non-Trivial property which can be completely known only to god. In my note it is shown that on plantinga's own definitions each individual x has exactly one essence, The trivial property of x-Identity. Thus (b) fails.

Práce si klade za cíl kriticky prozkoumat teorii J. S. Milla o rozlišení kvalitativní a kvantitativní charakteristice požitků (pleasure). Mill svoji teorii představil jako reakci na kritiku, že utilitární teorie vyhovuje jen zvířecí povaze lidské přirozenost a neuvažuje o vyšších schopnostech lidského ducha. Millova expozice teorie ale není v mnoha pasážích zcela jasná a průhledná. Práce se zaměřuje hlavně na prozkoumání problematického vztahu mezi kvantitativní stránkou a kvalitativní stránkou potěšení.

The article focuses on process management in public administration using the specific case study of the statutory city of Ostrava. Based on the selected part of the PAPRIS methodology, the process management is verified, and conclusions from the application of information system e-SMO are generalized. Ostrava is third the biggest city in Czech Republic with approximately 320 thousand citizen. Article describes experiences with SW implements, which are used for model of process in public administration. Particulary at local authority of Ostrava (...) town. Model of process is a basis for reengineering of process in state administration and preparation for implementation of big information systems. Mapping of process is providing implement and confirmation methodology to identify existing processes. Problem with its using consist in that, senior manager don’t informs, what organization is determination by processes. If are not described in given to organization current processes, or how would have had look new optimum processes, will not endeavour about reengineering successful. Procedural analysis namely offer tool and check methodology to identification current suit and it is possible him use either as instruction for reengineering function handling administrative and self-rule activities. Purpose of the article: The PAPRIS methodology was used when defining the objectives for implementation of the information system for public administration. This methodology has been elaborated by one of the authors and published in a very general scheme when solving many case studies,,. We assume that the PAPRIS is primarily a methodology with incorporated elements of procedural approach for project management in public administration information systems. The specific supporting process of communication between the client and the e-SMO system has been chosen for verification. The model of supporting communication process, created by ARIS tools, is crucial, and the structure of scripts is subsequently made. The aim of this article is to verify that the methodology is sufficient and appropriate to manage such a large project such, undoubtedly, is the e-SMO. Methodology/methods: Defined productive and non-productive processes with their defined process cuts represent a crucial category for the process structure of IS projects. This is fully accepted by the PAPRIS methodology. Process cuts are understood, in the logic modelling according to the PAPRIS methodology, as clearly defined logic directional cuts in three-dimensional space of all project processes. The process set is systemically categorized, in a given logic directional cut, into mutually disjoint process subsets, which are characterized by this particular directional operator. The directional operator always has a clear logical allocation that is based on the construction of a process view. Theoretically, an infinite number of process views can be used. One of the important issues in a methodology for the case studies includes the size of the research sample. It is usually assumed that there is no ideal number of cases and that the number between four and ten usually provides good results. Other authors defining against any quantitative standards for any determination of the sample size of the case studies, since such an approach denies the internal logic of this methodology and the richness of the information obtained from participants in the research. Research which is carried out using case studies does not aspire on compliance with the requirement the representativeness of the sample.. Methodology of case studies is among the established guidelines of qualitative research. Research on using case studies in the last 30 years has seen an extraordinary increase in social-scientific research, including research on business and management. Scientific aim: The essential aim of this study is to describe the way the process cut defines a productive process and non-productive process, in accordance with the PAPRIS methodology using the specific example. While the triggering mechanism of the project production process is an event causing its own production - i.e. the specific output with added value for the customer, the project of non-productive process is caused by the project management event. Therefore, it is caused by the need to control, monitor, track, inspect, evaluate outputs, decide and regulate the project implementation. Findings: Within the support of the communication process, two examples were used to verify the methodology. The global perspective on the process was created in ARIS tools and the communication between the call centre and the client was made in Visio tools. The PAPRIS methodology is based on the concept of process variability, which has been clearly formulated. The fundamental direction of the process development, anticipated changes and the opportunity to react to them in accordance with defined objectives of the PAIS project are guaranteed. (shrink)

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, (...) i. e., a molecular extensional η-construction. LetQ=C, whereC is a ℊ-object (over the extended base). Then the analysis ofImp has the form (QL′). The imperative sentences whose analyses have the form (QL) or (QL′) can be called ‘question-like imperative sentences’ or simply ‘QL-imperative sentences’. No imperative sentence whose analysis differs from (QL) and (QL\t') can be associated with a question. Therefore, no transformation of such an imperative sentence should result in a correct interrogative sentence. Fulfilling an order which is determined by a QL-imperative sentenceImp, one simultaneously gives the right answer to the questionQ (which is associated withImp). One who does not fulfil this order either wrongly answersQ or does not answerQ at all. (shrink)

Pár slov úvodem k dopisu, který poslal Pavel Tichý z University of Otago Pavlu Maternovi (který v té době ´pracoval´ na brněnské univerzitě bez možnosti učení a publikování). K dataci dopisu: Shoduji se s odhadem Dr. Raclavského, že jde patrně o r. 1975. Ti, kdo neprožili normalizaci, si těžko představí situaci. To nebylo tak, že můj přítel Tichý momentálně působí na Novém Zélandě a píše mi z momentálního zahraničního pobytu. Tichý byl emigrant, což mj. znamenalo, že žádnou z jeho (...) odborných statí nebylo možno u nás citovat, dále že dík faktu, o kterém každý věděl, že dopisy emigrantů jsou u nás na příslušných institucích otvírány, znamenala korespondence s emigrantem kádrovou skvrnu. O tom jsem tehdy nepřemýšlel, už proto, že četba Tichého dopisů byla nesmírně zajímavá. Byl jsem na shromažďování korespondence lajdák. Moje krátkozrakost zavinila, že se z této korespondence zachoval nepatrný zlomek. Dopis, který následuje, je ovšem obzvlášť zajímavý, a to z následujícího důvodu: Tichý měl už od šedesátých let – ještě v Československu – v hlavě zárodky svého přístupu k logice a logické analýze přirozeného jazyka (svědčí o tom jeho stati v tehdejším Filosofickém časopise, zejména stať „Smysl a procedura“ z r. 1968). Dopis, který zde uveřejňujeme, má však hodnotu historického dokumentu. Jde o první ´neformální´ formulaci jeho pojetí tzv. konstrukcí a jeho postoje k logice, což se postupně promítlo do systému Transparentní intenzionální logiky (TIL), vyloženého souvisle v monografii The Foundations of Frege´s Logic, vydané asi 13 let po tomto dopisu. Ze vzhledu dopisu je patrné, že byl psán na psacím stroji, což v těch letech bylo standardní. Musíme omluvit překlepy (ostatně to byl osobní dopis), pokud jde o nespisovnosti, vím, že Tichý ovládal češtinu velmi dobře, ale dával přednost psát přirozeně, blízko k hovorové češtině. Jistě připustíte, že jeho jazyk je zde velmi živý a že úpravy směrem ke spisovnému jazyku by narušily kouzlo bezprostřednosti a jistého emocionálního zaujetí, které z dopisu vyzařuje. Tichý posílal mně a Pavlovi Cmorejovi i nadále jednak osobní dopisy, jednak rukopisy svých statí, takže jsme měli výhodu být účastni procesu budování TIL, kterou oba (a dnes už nejenom my) pokládáme za podstatný přínos ke světové logice. --Pavel Materna.

Of two false theories, One can be, Intuitively, Closer to the truth than the other. The purpose of the article is to propose a rigorous explication of this intuitive notion.

We give four examples of theories in which Kreisel's Conjecture is false: (1) the theory PA(-) obtained by adding a function symbol minus, '−', to the language of PA, and the axiom ∀x∀y∀z (x − y = z) ≡ (x = y + z ⋁ (x < y ⋀ z = 0)); (2) the theory T of integers; (3) the theory PA(q) obtained by adding a function symbol q (of arity ≥ 1) to PA, assuming nothing about q; (4) the (...) theory PA(N) containing a unary predicate N(x) meaning 'x is a natural number'. In Section 6 we suggest a counterexample to the so called Sharpened Kreisel's Conjecture. (shrink)

Modal logic S5 is commonly viewed as an epistemic logic that captures the most basic properties of knowledge. Kripke proved a completeness theorem for the first-order modal logic S5 with respect to a possible worlds semantics. A multiagent version of the propositional S5 as well as a version of the propositional S5 that describes properties of distributed knowledge in multiagent systems has also been previously studied. This article proposes a version of S5-like epistemic logic of distributed knowledge with quantifiers ranging (...) over the set of agents, and proves its soundness and completeness with respect to a Kripke semantics.

Hence we obtain exponential lower bounds on the number of proof-lines in those systems. The main results have been given in [P.

Hrubeš, A lower bound for intuitionistic logic, Annals of Pure and Applied Logic 146 72–90]; here, we give considerably simplified (...) proofs, as well as some generalisations. (shrink)

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 expressions. He explicitly avoids presenting a definition of problems. In the present paper an attempt at such a definition (explication)—independent of but in harmony with Medvedev´s explication—is given together with the claim that every concept defines a problem. The paper treats just mathematical concepts, and so mathematical problems, and tries to show that this view makes it possible to take into account some links between conceptual systems and the ways how to replace a noneffective formulation of a problem by an effective one. To show this in concreto a wellknown Kleene’s idea from his (Introduction to metamathematics. D. van Nostrand, New York, 1952) is exemplified and explained in terms of conceptual systems so that a threatening inconsistence is avoided. (shrink)

The 1989 revolutions in Central and Eastern Europe and the subsequent transitions have commonly been interpreted in political terms, as movements towards democracy, or in economic terms, as escape from the command economy towards the free market. We revisit the problem to suggest a different reading. We argue that in the legitimization crisis of real socialism, a pivotal role was played by the burden of social oversaturation and bureaucratic arbitrariness, which met its desired alternative in social imaginaries of impersonal, objective (...) social system. For the citizens of Central and East European countries, this fantasy was matched by the promise of the free market, which was morally contrasted to the experience of daily life under late socialism. We argue that this desire to escape from arbitrariness to objectivity is a particularly strong motive in the imaginary of modernity which found one of its historical manifestations in the disappointment with real socialism.

Using the original theory of social identity the article considers ethnicity, quasi-ethnicity, and nationality in a context of ethnopolitics. The article introduces logically strong definitions for mentioned identities, shows the possibility of exploding a nationalism basing on any quasi-ethnical social identity – with some historical examples. One non-banal result: the functions of nation in USSR were carried on by the Communist Party.

Motivated by the problem of finding finite versions of classical incompleteness theorems, we present some conjectures that go beyond NP ≠ coNP. These conjectures formally connect computational complexity with the difficulty of proving some sentences, which means that high computational complexity of a problem associated with a sentence implies that the sentence is not provable in a weak theory, or requires a long proof. Another reason for putting forward these conjectures is that some results in proof complexity seem to be (...) special cases of such general statements and we want to formalize and fully understand these statements. Roughly speaking, we are trying to connect syntactic complexity, by which we mean the complexity of sentences and strengths of the theories in which they are provable, with the semantic concept of complexity of the computational problems represented by these sentences. -/- We have introduced the most fundamental conjectures in our earlier works. Our aim in this article is to present them in a more systematic way, along with several new conjectures, and prove new connections between them and some other statements studied before. (shrink)

“Eco-labels” are an increasingly important form of private regulation for sustainability in areas such as carbon emissions, water consumption, ethical sourcing, or organic produce. The growing interest and popularity of eco-labels has also been coupled with growing concerns about their credibility, in part because the standard-setting and conformity assessment practices that eco-labels adopt exhibit striking differences. In this paper, we assess which assurance practices contribute to eco-labels being perceived as better governed, in the eyes of experts as well as the (...) media. Unlike previous studies, which are mostly conceptual, qualitative, or focused on one or few eco-labels, we study a large set of eco-labels, combining data from three different sources. Our findings suggest that experts and media are primarily concerned about “re-assurance” practices, looking for one or preferably multiple layers of “re-assurance” that independent parties are overseeing the eco-label and the firms certified under it.
