Wychodząc od metaforycznego (figuralnego) ujęcia problemu zła, w oparciu o wybrane przemyślenia Leszka Kołakowskiego, rozważania składające się na artykuł zmierzają do namysłu nad „złem w polityce” w sensie niedomagań i nadużyć wolności: pokus władzy autokratycznej i totalitarnej. Dotyczą antropologicznego i politycznego przekraczania granic wolności kosztem (aż do zniesienia) wolności innych. Evil Politics or Trouble with the Devil. Reflections on the Political Demonology of Leszek Kołakowski Proceeding from a metaphorical (figurative) account of the problem of evil, and based on (...) class='Hi'>Leszek Kołakowski’s selected thoughts, this paper’s considerations aim to deliberate on “evil in politics” in the spirit of the shortcomings and excesses of freedom: namely, the lure of autocratic and totalitarian power. At issue is how the bounds of freedom are anthropologically and politically transgressed at the expense (to the point of abolishing) the freedom of others. (shrink)

ABSTRACT The paper examines between democracy and a utopia of everydayness. The paper refers to the democratic system in Poland through the prism of everyday life and it shows the sources of the rise of populism in the feeling of losing control over our own lives. Therefore, the paper investigates the relationships between everyday life and politics and the complicated connections between everydayness and modernity. The next section is devoted to the emergence of the utopia of everydayness in Herbert Marcuse’s (...) psychoanalytic thought and its appropriation in the student movements of sixties. Finally, the categories of microphysics of emancipation and somapower are introduced and it is shown that these notions can be useful in the construction of the utopia of everydayness which would support the democratic system.

Leszek Kolakowski delves into some of the most intellectually vigorous questions of our time in this remarkable collection of essays garnished with his characteristic wit. Ten of the essays have never appeared before in English. "Exemplary.

Polish philosopher Leszek Kolakowski is renowned worldwide for wrestling with serious philosophical conundrums with dazzling elegance. In this new book, he turns his characteristic wit to important themes of ordinary life, from the need for freedom to the wheel of fortune, from the nature of God to the ambiguities of betrayal. Extremely lucid and lacking in intellectual pretension, these essays speak in everyday language, spurring the reader’s own thoughts and providing a handle on which to debate and think about (...) the themes. The eighteen essays cover the following topics: power, fame, equality, lying, toleration, travel, virtue, collective responsibility, the wheel of fortune, betrayal, violence, boredom, freedom, luxury, God, respect for nature, superstition, and national stereotypes.

Leszek Kolakowski discusses, in a highly original way, the arguments for and against the existence of God as they have been conducted through the ages. He examines the critiques of religious belief, from the Epicureans through Nietzsche to contemporary anthropological inquiry, the assumptions that underlie them, and the counter-arguments of such apologists as Descartes, Leibniz, and Pascal. His exploration of the philosophy of religion covers the historical discussions of the nature and existence of evil, the importance of the concepts (...) of failure and eternity to the religious impulse, the relationship between skepticism and mysticism, and the place of reason, understanding, and in models of religious thought. He examines why people, throughout known history, have cherished the idea of eternity and existence after death, and why this hope has been dependent on the worship of an eternal reality. He confronts the problems of meaning in religious language. (shrink)

Celem artykułu jest próba rekonstrukcji rozwoju duchowego Zaratustry, głównego bohatera dzieła Nietzschego Tako rzecze Zaratustra. Ów rozwój polega na osiąganiu trzech stadiów świadomości: fazy konformistycznego wielbłąda, przepełnionego negacją lwa i finalnie dziecka afirmującego życie. Metodologia badań zastosowana w artykule opiera się na analizie, rekonstrukcji i syntezie tekstu Tako rzecze Zaratustra. Przeprowadzone badania osadzone są w kontekście tezy Heideggera o komplementarności głównych aspektów nietzscheanizmu: woli mocy i wiecznego powrotu. Zaratustra, aby przeistoczyć się w lwa, a następnie w dziecko, będzie musiał odkryć (...) i zaakceptować ową komplementarność. Głównym antagonistą proroka jest duch ciężkości, symbolizujący negację życia i destruktywną miłość bliźniego. (shrink)

Journal of Mathematical Logic, Volume 22, Issue 03, December 2022. We study a new class of NP search problems, those which can be proved total using standard combinatorial reasoning based on approximate counting. Our model for this kind of reasoning is the bounded arithmetic theory [math] of [E. Jeřábek, Approximate counting by hashing in bounded arithmetic, J. Symb. Log. 74(3) (2009) 829–860]. In particular, the Ramsey and weak pigeonhole search problems lie in the new class. We give a purely computational (...) characterization of this class and show that, relative to an oracle, it does not contain the problem CPLS, a strengthening of PLS. As CPLS is provably total in the theory [math], this shows that [math] does not prove every [math] sentence which is provable in bounded arithmetic. This answers the question posed in [S. Buss, L. A. Kołodziejczyk and N. Thapen, Fragments of approximate counting, J. Symb. Log. 79(2) (2014) 496–525] and represents some progress in the program of separating the levels of the bounded arithmetic hierarchy by low-complexity sentences. Our main technical tool is an extension of the “fixing lemma” from [P. Pudlák and N. Thapen, Random resolution refutations, Comput. Complexity, 28(2) (2019) 185–239], a form of switching lemma, which we use to show that a random partial oracle from a certain distribution will, with high probability, determine an entire computation of a [math] oracle machine. The introduction to the paper is intended to make the statements and context of the results accessible to someone unfamiliar with NP search problems or with bounded arithmetic. (shrink)

"[An] important essay by a philosopher who more convincingly than any other I can think of demonstrates the continuing significance of his vocation in the life of our culture."--Karsten Harries, The New York Times Book Review With The Presence of Myth , Kolakowski demonstrates that no matter how hard man strives for purely rational thought, there has always been-and always will be-a reservoir of mythical images that lend "being" and "consciousness" a specifically human meaning. "Kolakowski undertakes a philosophy of culture (...) which extends to all realms of human intercourse--intellectual, artistic, scientific, and emotional. . . . [His] book has real significance for today, and may well become a classic in the philosophy of culture."-- Anglican Theological Review. (shrink)

In recent years part of the literature on probabilistic causality concerned notions stemming from Reichenbach’s idea of explaining correlations between not directly causally related events by referring to their common causes. A few related notions have been introduced, e.g. that of a “common cause system” (Hofer-Szabó and Rédei in Int J Theor Phys 43(7/8):1819–1826, 2004) and “causal (N-)closedness” of probability spaces (Gyenis and Rédei in Found Phys 34(9):1284–1303, 2004; Hofer-Szabó and Rédei in Found Phys 36(5):745–756, 2006). In this paper we (...) introduce a new and natural notion similar to causal closedness and prove a number of theorems which can be seen as extensions of earlier results from the literature. Most notably we prove that a finite probability space is causally closed in our sense iff its measure is uniform. We also present a generalisation of this result to a class of non-classical probability spaces. (shrink)

The current heated debate on the deteriorating status of the university raises a range of pertinent questions, including: What role can the humanities play in culture today in the face of the crisis of higher education? To answer this question, the authors begin by problematizing the relationship between culture, the humanities, and education. In the second part of the paper, they examine the changing role of the humanities in conjunction with the understandings of culture, and outline three salient ways in (...) which culture is conceived of today. Subsequently, they focus on the loss of the dominant status that culture suffered when everyday life was discovered in modernity. In the third part, they argue that everyday life, or rather social representations of everyday life and its practices, are currently becoming the chief criterion for assessing culture, the humanities, and education. However, everyday life remains complex both in theoretical conceptualizations and in research observations. For example, everyday life harbors a range of risks and anxieties which are veiled by its own obviousness and reinforced by socialization. The authors conclude that, given this, everyday life in democratic societies calls for the work of understanding, support, affirmation, and criticism, in which the humanities can retain their superior status. In the fourth part, the authors discuss non-consensual democracy, critical community, and the pedagogy of asylum as the forms of organization and action that promote an auspicious interconnection of culture, the humanities, and education.

Since its first introduction by Hans Reichenbach, many philosophers have claimed to refute the common cause principle. The situation is not so straightforward, though: validity of the principle remains an open question. The book traces different formulations of the principle, and provides proofs of a few pertinent theorems, settling the relevant questions in various probability spaces. It offers both philosophical insight and mathematical rigor.

We study the first-order consequences of Ramsey’s Theorem fork-colourings ofn-tuples, for fixed$n, k \ge 2$, over the relatively weak second-order arithmetic theory$\mathrm {RCA}^*_0$. Using the Chong–Mourad coding lemma, we show that in a model of$\mathrm {RCA}^*_0$that does not satisfy$\Sigma ^0_1$induction,$\mathrm {RT}^n_k$is equivalent to its relativization to any proper$\Sigma ^0_1$-definable cut, so its truth value remains unchanged in all extensions of the model with the same first-order universe.We give a complete axiomatization of the first-order consequences of$\mathrm {RCA}^*_0 + \mathrm {RT}^n_k$for$n \ge (...) 3$. We show that they form a non-finitely axiomatizable subtheory of$\mathrm {PA}$whose$\Pi _3$fragment coincides with$\mathrm {B} \Sigma _1 + \exp $and whose$\Pi _{\ell +3}$fragment for$\ell \ge 1$lies between$\mathrm {I} \Sigma _\ell \Rightarrow \mathrm {B} \Sigma _{\ell +1}$and$\mathrm {B} \Sigma _{\ell +1}$. We also give a complete axiomatization of the first-order consequences of$\mathrm {RCA}^*_0 + \mathrm {RT}^2_k + \neg \mathrm {I} \Sigma _1$. In general, we show that the first-order consequences of$\mathrm {RCA}^*_0 + \mathrm {RT}^2_k$form a subtheory of$\mathrm {I} \Sigma _2$whose$\Pi _3$fragment coincides with$\mathrm {B} \Sigma _1 + \exp $and whose$\Pi _4$fragment is strictly weaker than$\mathrm {B} \Sigma _2$but not contained in$\mathrm {I} \Sigma _1$.Additionally, we consider a principle$\Delta ^0_2$-$\mathrm {RT}^2_2$which is defined like$\mathrm {RT}^2_2$but with both the$2$-colourings and the solutions allowed to be$\Delta ^0_2$-sets rather than just sets. We show that the behaviour of$\Delta ^0_2$-$\mathrm {RT}^2_2$over$\mathrm {RCA}_0 + \mathrm {B}\Sigma ^0_2$is in many ways analogous to that of$\mathrm {RT}^2_2$over$\mathrm {RCA}^*_0$, and that$\mathrm {RCA}_0 + \mathrm {B} \Sigma ^0_2 + \Delta ^0_2$-$\mathrm {RT}^2_2$is$\Pi _4$- but not$\Pi _5$-conservative over$\mathrm {B} \Sigma _2$. However, the statement we use to witness failure of$\Pi _5$-conservativity is not provable in$\mathrm {RCA}_0 +\mathrm {RT}^2_2$. (shrink)

In this paper we give a positive answer to a problem posed by Hofer-Szabó and Rédei (Int. J. Theor. Phys. 43:1819–1826, 2004) regarding the existence of infinite Reichenbachian common cause systems (RCCSs). An example of a countably infinite RCCS is presented. It is also determined that no RCCSs of greater cardinality exist.

We show, under the assumption that factoring is hard, that a model of PV exists in which the polynomial hierarchy does not collapse to the linear hierarchy; that a model of S21 exists in which NP is not in the second level of the linear hierarchy; and that a model of S21 exists in which the polynomial hierarchy collapses to the linear hierarchy. Our methods are model-theoretic. We use the assumption about factoring to get a model in which the weak (...) pigeonhole principle fails in a certain way, and then work with this failure to obtain our results. As a corollary of one of the proofs, we also show that in S21 the failure of WPHP (for Σb1 definable relations) implies that the strict version of PH does not collapse to a finite level. (shrink)

According to the commonsensical model of educating researchers, young researchers must first acquire the knowledge achieved thus far and then solve new problems by developing applications of the accepted theory. This model, which presupposes a positivist theory of science, is incapable of explaining why the major breakthroughs in science have been carried out by young researchers. On the idealizational view of science, it becomes clear that commonsensical model must be rejected and replaced with an alternative, according to which the primary (...) duty of young researchers is to revise the existing theories. It is the young researchers who are usually creative enough, ignorant enough, and exhibit a sufficient degree of nonconformism, to be capable of developing really new scientific theories. (shrink)

I claim that objective consequentialism faces a problem stemming from the existence in some situations of a plurality of chances relevant to the outcomes of an agent’s acts. I suggest that this phenomenon bears structural resemblance to the well-known Reference Class problem. I outline a few ways in which one could attempt to deal with the issue, suggesting that it is the higher-level chance that should be employed by OC.

_God Owes Us Nothing_ reflects on the centuries-long debate in Christianity: how do we reconcile the existence of evil in the world with the goodness of an omnipotent God, and how does God's omnipotence relate to people's responsibility for their own salvation or damnation. Leszek Kolakowski approaches this paradox as both an exercise in theology and in revisionist Christian history based on philosophical analysis. Kolakowski's unorthodox interpretation of the history of modern Christianity provokes renewed discussion about the historical, intellectual, (...) and cultural omnipotence of neo-Augustinianism. "Several books a year wrestle with that hoary conundrum, but few so dazzlingly as the Polish philosopher's latest."—Carlin Romano, _Washington Post Book World_ "Kolakowski's fascinating book and its debatable thesis raise intriguing historical and theological questions well worth pursuing."—Stephen J. Duffy, _Theological Studies_ "Kolakowski's elegant meditation is a masterpiece of cultural and religious criticism."—Henry Carrigan, _Cleveland Plain Dealer_. (shrink)

Since its introduction by Hans Reichenbach, many philosophers have claimed to refute the idea – known as the common cause principle – that any surprising correlation between any two factors that do not directly influence one another is due to some common cause. For example, falsity of the principle is frequently inferred from falsifiability of Bell’s inequalities. The author demonstrates, however, that the situation is not so straightforward. There is more than one version of the principle formulated with the use (...) of different variants of Reichenbach-inspired notions; their falsity still remains an open question. The book traces different formulations of the principle and provides proofs of a few pertinent theorems, settling the relevant questions in various probability spaces. In exploring mathematical and philosophical issues surrounding the principle, the book offers both philosophical insight and mathematical rigor. (shrink)

The subject of this study considers the role played by the two models in transformation of Polish society: the knightly ethos and the bourgeois ethos. The main research question is whether these patterns are competitive with each other or complementary? Must the chivalric ethos disappear from social consciousness so that a bourgeois ethos can appear in its place, or are these value systems complementary? In the literature on the subject, as well as in common knowledge, one often encounters claims that (...) one can be either a romantic or a pragmatist, and that it is impossible to combine these two attitudes neither in the sphere of ideas nor in action. It is for this reason that the romantic approach derived from the chivalric ethos is now often analyzed within the framework of the so-called critical theory. In other words, it is deconstructed in order to make room for a paradigm that appeals to utilitarianism and constructivism. The thesis of this article is as follows: the romantic chivalric paradigm, despite many differences, is not opposed to the bourgeois paradigm. These approaches serve to realize the same values and virtues, but under different historical conditions and in dissimilar social and civilizational contexts. The text is based on the analysis of the two ethical models presented in sociological literature, in selected literary texts, and in biographies of selected historical figures. The conclusion presents findings of the undertaken analysis. In the author’s opinion, the two ethoses can play positive roles in Poland’s modernization and they are not completely mutually exclusive, as it is the case in some approaches analyzing social transformations that took place in Poland in the 19th and 20th centuries. This conclusion is also valid in the times of change that Poland is facing today. (shrink)

This article presents a fragment of the history of psychology in Poland, discussing its development in the years 1945–56, which saw sweeping political and geographical transformations. In that maelstrom of history, psychology was particularly affected by the effects of geopolitical changes, which led to its symbolic ‘arrest’ in 1952, when psychological practice was prohibited and all psychology courses were abolished at universities. Amnesty was declared only in 1956, with the demise of the so-called Stalinist ‘cult of personality’ and the onset (...) of a turbulent period when the crimes of the Stalinist era were prosecuted. We have adopted three time frames for our description and analysis of this dramatic period in the development of psychology in Poland. ‘The past’ is a story about the flourishing of Polish psychology before World War Two and the hopes for the discipline’s restoration after the war. ‘The present’, as the core of this narrative, represents the events of 1950–56. ‘The future’ refers to the period when Stalinist abuses were prosecuted during the Thaw, following the collapse of the Stalinist dictatorship, and the resurgence of Polish psychologists’ hopes for resurrecting their discipline. In all these periods, the narrative is interwoven with the story of the Polish psychologist Mieczysław Kreutz, who offers a model example of the hypothesized dependence of scientific research on sociopolitical change.

The paper is aimed at discussing two interpretations of pragmatism in a broader framework of general rules of philosophical interpretation. J. Habermas' and R. Rorty's uses of pragmatism are considered in detail and confronted with general assumptions of pragmatic philosophy. It is shown that in both cases the original ideas of pragmatism are changed in order to fit the philosophies of interpreters. The paper ends with discussion of a possibility of applying the rule of interpretative charity and dialogue to philosophical (...) analyses. Key Words: communication • dialogue • interpretation • postmodernism • pragmatism • tradition • transcendentalism. (shrink)
