The great revolutions of modern times have been analysed from various angles, but their civilizational aspects and contexts have on the whole been neglected. More specifically, the major 20th-century revolutions can be seen as particularly important cases of intercivilizational encounters. They represent different responses to the ascendant and challenging civilization of the West. The Western civilizational trajectory (or set of trajectories), based on a shift from fideism to empiricism and on multiple social dynamics fuelled by this cultural reorientation (such as (...) those of the capittalist economy and the one-nation-state), is selectively appropriated by non-Western societies which at the same time reject the less adaptable parts of the West in the name of traditional or invented alternatives. Russia, China, Turkey and Iran are analysed as variations of this recurrent pattern. At one end of the spectrum, the Russian revolution aspired to transcend Western models on the basis of a more radical interpretation of their own principles; at the other, the Iranian revolution, made up of several episodes with intervals in between, has been characterized by an exceptionally tenacious - and in some ways inventive - defence of a pre-existing civilizational identity.

In this ambitious exploration of humanity and civilizations throughout history, major historical events and processes in the history of mankind are looked at in order to understand the "currents" of history. Jaroslav Krejc analyzes the whole history of civilization and considers historical events such as feudalism and the development of science. By bringing both sociological and historical insights to this broad subject, and particular attention to different types of knowledge (such as religion and its impact state law labor and (...) ownership), the book offers insights into the future of civilization and shifting global power.

Modern sociology has set itself up as a specialised discipline dissociating itself from the broad-ranging theories of development of the early sociologists and breaking the links with economics, social anthropology and politics which had formed such an exciting unity in their works or at least in their lives.

We investigate several ideal versions of the pseudointersection number \(\mathfrak {p}\), ideal slalom numbers, and associated topological spaces with the focus on selection principles. However, it turns out that well-known pseudointersection invariant \(\mathtt {cov}^*({\mathcal I})\) has a crucial influence on the studied notions. For an invariant \(\mathfrak {p}_\mathrm {K}({\mathcal J})\) introduced by Borodulin-Nadzieja and Farkas (Arch. Math. Logic 51:187–202, 2012), and an invariant \(\mathfrak {p}_\mathrm {K}({\mathcal I},{\mathcal J})\) introduced by Repický (Real Anal. Exchange 46:367–394, 2021), we have $$\begin{aligned} \min \{\mathfrak (...) {p}_\mathrm {K}({\mathcal I}),\mathtt {cov}^*({\mathcal I})\}=\mathfrak {p},\qquad \min \{\mathfrak {p}_\mathrm {K}({\mathcal I},{\mathcal J}),\mathtt {cov}^*({\mathcal J})\}\le \mathtt {cov}^*({\mathcal I}), \end{aligned}$$ respectively. In addition to the first inequality, for a slalom invariant \(\mathfrak {sl_e}({\mathcal I},{\mathcal J})\) introduced in Šupina (J. Math. Anal. Appl. 434:477–491, 2016), we show that $$\begin{aligned} \min \{\mathfrak {p}_\mathrm {K}({\mathcal I}),\mathfrak {sl_e}({\mathcal I},{\mathcal J}),\mathtt {cov}^*({\mathcal J})\}=\mathfrak {p}. \end{aligned}$$ Finally, we obtain a consistency that ideal versions of the Fréchet–Urysohn property and the strictly Fréchet–Urysohn property are distinguished.

In his proof of the first incompleteness theorem, Kurt Gödel provided a method of showing the truth of specific arithmetical statements on the condition that all the axioms of a certain formal theory of arithmetic are true. Furthermore, the statement whose truth is shown in this way cannot be proved in the theory in question. Thus it may seem that the relation of logical consequence is wider than the relation of derivability by a pre-defined set of rules. The aim of (...) this paper is to explore under which assumptions the Gödelian statement can rightly be considered a logical consequence of the axioms of the theory in question. It is argued that this is the case only when the all the theorems of the theory in question are understood as statements of the same kind as statements of arithmetic and statements about provability in the theory, and only if the language of the theory contains logical expressions allowing to include certain predicates of meta-language in the language of the theory.

Growth modelling is of interest to scientists in various disciplines. In our article, we will collect 17 models designed for growth modelling, appraise these models and contribute to the discussion of their applicability. The merit of the paper lies in studying the convergence properties of nonlinear regression in selected models. Our studies will be performed mainly concerning the quality of the obtained estimates, which are closely related to the intrinsic curvature of the model according to Bates and Watts. This curvature (...) determines the size of the linearization domains. Only if the initial solution is in this domain, then the convergence of the estimate in nonlinear regression is guaranteed. The primary goal is to design a methodology for selecting a growth model. We will demonstrate fruitfulness of our methodology on the weight measurements of 10 calves under 25 months of age from cowsheds in the village Záluží in the Czech Republic. Estimated parameters of growth curves, sizes of linearization domain, calculated residues and coefficients of determination indices will be the subject of discussion. (shrink)

There has been much controversy over the completeness and unity of Euripides᾽Heraclidaein the last two centuries. Hermann᾽s characterization of the play as a heavily mutilated piece, which was adopted by Kirchhoff, Wilamowitz, Nauck and Murray, prevailed for a long time. Wilamowitz's thesis that theHeraclidaewas revised by the ancient director found its adherents. It was Günther Zuntz who led the general offensive against this widely accepted opinion and whose critical scrutiny reversed the view of the play. According to Zuntz, the play (...) has come down to us substantially as it was written. The alleged mutilation, as well as the specific dramatic technique, shortness and swiftness of theHeraclidae, also influenced the general evaluation of the play as a minor or odd piece. It was Günter Zuntz again and also Franz Stoessl who reconstituted the reputation of theHeraclidae. Today Euripides᾽Heraclidaeis studied and recognized as a classicalHikesiedrama, a play deeply rooted in Athenian ideology and in the social and religious context of fifth-century Athens, and representing various aspects of communal life. Since the play has been interpreted and scrutinized from a very wide range of perspectives, I do not aim at a radically new general interpretation of theHeraclidae, but I would like to make a short remark on an aspect of it which has, as far as I know, been neglected or only briefly referred to: the term ἀμηχανία in crucial passages of the play, which signifies, or rather describes, a situation which is desperate, hopeless, and with no way out. I would like to show that for the characters in theHeraclidaewho follow the ideal of justice, in contrast to those who prefer profit, no situation is hopeless, even as it was not for Heracles, who managed to do things which could be evaluated as impossible. On the other hand, those who opt for the Heraclean ideal have to prepare to face the ultimate challenges. (shrink)

Filozofické pojednání vysvětluje z hlediska marxistického pojetí dějin základní otázky společenského dění, úlohu materiálních činitelů ve vývoji společnosti, protiklad materiálního a ideálního ve společnosti. Druhé vydání je upraveno s přihlédnutím ke kritickým připomínkám.

Odborná práce z oboru hudební teorie. Navazuje na knihu téhož autora "Teoretické základy harmonie s hľadiska vedeckej filozofie", jež vyšla r. 1954. Soustřeďuje pozornost k oněm názorům a teoriím, které jsou z hlediska filosofického ovlivněny idealistickým postojem. V první části sleduje a hodnotí vlivy idealismu na nauku o harmonii v 19. a 20. století, v druhé se obírá předpoklady dialektického materialismu v hudební teorii.
