This book is a meditation on the different aspects of colour, particularly its relationship to healing. Drawing on examples from natural science and spiritual science, Klocek focuses on the real essence of colours and how they relate to human beings in our physical body and soul. From Newton to Rudolf Steiner, and including the development of artistic pigments, this enlightening book shows how colour can be linked to healing with artistic therapies, homeopathy and flower essences.Illustrated in colour with numerous (...) diagrams and examples of art from the Middle Ages to the twentieth century, this book offers surprising insights into a subject that is integral to our everyday life and development.

'Holographic' relations between theories have become a main theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by Gerard 't Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic 'AdS/CFT' duality was introduced, which since has been heavily studied in the string theory community and beyond. Recently, Erik Verlinde has proposed (...) that even Newton's law of gravitation can be related holographically to the thermodynamics of information on screens. We discuss inter-theoretical relations in these scenarios: what is the status of the holographic relation in them and in what sense is gravity, or spacetime, emergent? (shrink)

Refinements in Darwin’s theory of the origin of a moral sense create a framework equipped to organize and integrate contemporary theory and research on morality. Morality originated in deferential, cooperative, and altruistic ‘‘social instincts,’’ or decision-making strategies, that enabled early humans to maximize their gains from social living and resolve their conflicts of interest in adaptive ways. Moral judgments, moral norms, and conscience originated from strategic interactions among members of groups who experienced confluences and conflicts of interest. Moral argumentation buttressed (...) by moral reasoning is equipped to generate universal and impartial moral standards. Moral beliefs and standards are products of automatic and controlled information-processing and decision making mechanisms. To understand how people make moral decisions, we must understand how early evolved mechanisms in the old brain and recently evolved mechanisms in the new brain are activated and how they interact. Understanding what a sense of morality is for helps us understand what it is. (shrink)

Experimental evidence of the last decades has made the status of ``collapses of the wave function'' even more shaky than it already was on conceptual grounds: interference effects turn out to be detectable even when collapses are typically expected to occur. Non-collapse interpretations should consequently be taken seriously. In this paper we argue that such interpretations suggest a perspectivalism according to which quantum objects are not characterized by monadic properties, but by relations to other systems. Accordingly, physical systems may possess (...) different properties with respect to different ``reference systems''. We discuss some of the relevant arguments, and argue that perspectivalism both evades recent arguments that single-world interpretations are inconsistent and eliminates the need for a privileged rest frame in the relativistic case.

Saunders has recently claimed that “identical quantum particles” with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black’s spheres, for example). Weakly discernible objects have all their qualitative properties in common but nevertheless differ from each other by virtue of (a generalized version of) Leibniz’s principle, since they stand in relations an entity cannot have to itself. This notion of weak discernibility has been criticized as question begging, but we (...) defend and accept it for classical cases likes Black’s spheres. We argue, however, that the quantum mechanical case is different. Here the application of the notion of weak discernibility indeed is question begging and in conflict with standard interpretational ideas. We conclude that the introduction of the conceptual resource of weak discernibility does not change the interpretational status quo in quantum mechanics. (shrink)

It is argued that the symmetry and anti-symmetry of the wave functions of systems consisting of identical particles have nothing to do with the observational indistinguishability of these particles. Rather, a much stronger conceptual indistinguishability is at the bottom of the symmetry requirements. This can be used to argue further, in analogy to old arguments of De Broglie and Schrödinger, that the reality described by quantum mechanics has a wave-like rather than particle-like structure. The question of whether quantum statistics alone (...) can give rise to empirically observable correlations between results of distant measurements is also discussed. (shrink)

According to classical physics particles are basic building blocks of the world. These classical particles are distinguishable objects, individuated by unique combinations of physical properties. By contrast, in quantum mechanics the received view is that particles of the same kind are physically indistinguishable from each other and lack identity. This doctrine rests on the quantum mechanical symmetrization postulates together with the “factorist” assumption that each single particle is represented in exactly one factor space of the tensor product Hilbert space of (...) a many-particle system. Even though standard in theoretical physics and the philosophy of physics, the assumption of factorism and the ensuing indistinguishability of particles are problematic. Particle indistinguishability is irreconcilable with the everyday meaning of “particle”, and also with how this term is used in the practice of physics. Moreover, it is a consequence of the standard view that identical quantum particles remain indistinguishable even in the classical limit, which makes a smooth transition to the classical particle concept impossible. Lubberdink and Dieks and Lubberdink have proposed an alternative conception of quantum particles that does not rely on factorism and avoids these difficulties. We further explain and discuss this alternative framework here. One of its key consequences is that particles in quantum theory are not fundamental but emergent; another that once they have emerged, quantum particles are always physically distinguishable and thus possess a physically grounded identity.

Concern about the integrity of empirical research has arisen in recent years in the light of studies showing the vast majority of publications in academic journals report positive results, many of these results are false and cannot be replicated, and many positive results are the product of data dredging and the application of flexible data analysis practices coupled with selective reporting. While a number of potential solutions have been proposed, the effects of these are poorly understood and empirical evaluation of (...) each would take many years. We propose that methods from the systems sciences be used to assess the effects, both positive and negative, of proposed solutions to the problem of declining research integrity such as study registration, Registered Reports, and open access to methods and data. In order to illustrate the potential application of systems science methods to the study of research integrity, we describe three broad types of models: one built on the characteristics of specific academic disciplines; one a diffusion of research norms model conceptualizing researchers as susceptible, “infected” and recovered; and one conceptualizing publications as a product produced by an industry comprised of academics who respond to incentives and disincentives.

This study proposes a conceptual model to explain persistent, accepted-as-normal corporate wrongdoing (hereafter banality of wrongdoing), particularly for high performance organizations. The model describes five explanatory variables: the culture of competition, ends-biased leadership, missionary zeal, legitimizing myth, and the corporate cocoon. Our thesis is that the nature of competition drives both legitimate and illegitimate goal-seeking to adopt an iconoclastic (rule-breaking) orientation. High performance organizations are favorable hosts for wrongdoing because high performance requires aggressive behavior at the ethical margins of what (...) is acceptable. The way leadership reacts to competition sets the stage for ethical or unethical cultures to develop. Ends-biased leadership will project strong vision, using ideology and legitimizing myth as tools to inspire and motivate. The resulting missionary zeal justifies using questionable means because of the perceived value of the end. One critical method for building strong culture is creating a sense of being separate and apart from the ordinary. This cocoon effect may create a self-referential value system that is significantly at odds with mainstream culture and in which wrongdoing is banal. We intend an empirical study of the variables described in this model. (shrink)

Extreme narcissistic organizations are unable to behave ethically because they lack a moral identity. While such organizations are not necessarily unethical intentionally, they become self-obsessed and use a sense of entitlement, self-aggrandizement, denial, and rationalizations to justify anything they do. Extreme narcissistic organizations might develop formal ethics programs, but such programs will have little effect on behavior.

In his general theory of relativity Einstein sought to generalize the special-relativistic equivalence of inertial frames to a principle according to which all frames of reference are equivalent. He claimed to have achieved this aim through the general covariance of the equations of GR. There is broad consensus among philosophers of relativity that Einstein was mistaken in this. That equations can be made to look the same in different frames certainly does not imply in general that such frames are physically (...) equivalent. We shall argue, however, that Einstein's position is tenable. The equivalence of arbitrary frames in GR should not be equated with relativity of arbitrary motion, though. There certainly are observable differences between reference frames in GR. The core of our defense of Einstein's position will be to argue that such differences should be seen as fact-like rather than law-like in GR. By contrast, in classical mechanics and in special relativity the differences between inertial systems and accelerated systems have a law-like status. The fact-like character of the differences between frames in GR justifies regarding them as equivalent in the same sense as inertial frames in SR. (shrink)

It has often been remarked that Bohr's writings on the interpretation of quantum mechanics make scant reference to the mathematical formalism of quantum theory; and it has not infrequently been suggested that this is another symptom of the general vagueness, obscurity and perhaps even incoherence of Bohr's ideas. Recent years have seen a reappreciation of Bohr, however. In this article we broadly follow this "rehabilitation program". We offer what we think is a simple and coherent reading of Bohr's statements about (...) the interpretation of quantum mechanics, basing ourselves on primary sources and making use of and filling lacunas in|recent secondary literature. We argue that Bohr's views on quantum mechanics are more firmly connected to the structure of the quantum formalism than usually acknowledged, even though Bohr's explicit use of this formalism remains on a rather global and qualitative level. In our reading, Bohr's pronouncements on the meaning of quantum mechanics should first of all be seen as responses to concrete physical problems, rather than as expressions of a preconceived philosophical doctrine. In our final section we attempt a more detailed comparison with the formalism and conclude that Bohr's interpretation is not far removed from present-day non-collapse interpretations of quantum mechanics.

Hong Kong is undergoing two overlapping crises: social unrest over anti-government protests, and COVID-19. The media has linked these events in both objective and subjective ways. While some liken the social unrest to COVID-19, others do the opposite. This is an intriguing real-world instance of source-target reversibility with interchangeable source and target resulting in two apt variants. This paper reports a survey study of the links between crisis perceptions and the aptness of metaphor variants. Participants (N = 93) rated 30 (...) matched items on the effects of both crises on trust in governance, interpersonal relations, the economy, physical/mental health, and Hong Kong’s future. This determined, for each participant, a correlation coefficient reflecting perceived structural similarity, and absolute/raw difference scores reflecting perceived substantive similarity of the crises. They then explained which (or neither) of two constructed headlines depicting the SOCIAL UNREST as COVID-19 or COVID-19 as the SOCIAL UNRESTwas more apt. Logistic regression analyses showed that i) metaphor aptness was predictable from structural but not substantive similarity, and ii) the worse crisis was preferred as source domain, but only for its more experientially concrete aspects. The study exemplifies socio-culturally situated’ theoretical investigation and how metaphor research can shed light on crisis perceptions. (shrink)

As interpreted by Pattee, von Neumann’s Theory of Self-Reproducing Automata has proved to be a useful tool for understanding some of the difficulties and paradoxes of molecular biosemiotics. But is its utility limited to molecular systems or is it more generally applicable within biosemiotics? One way of answering that question is to look at the Theory as a model for one particular high-level biosemiotic activity, human language. If the model is not useful for language, then it certainly cannot be generally (...) useful to biosemiotics. Beginning with the Universal Turing Machine and continuing with von Neumann’s Theory and Pattee’s interpretation, the properties of universality, programmability, underspecification, complementarity of description/construction, and open-ended evolutionary potential are shown to be usefully applicable to language, thus opening a new line of inquiry in biosemiotics.

Global lockdowns during the COVID-19 pandemic have offered many people first-hand experience of how their daily online activities threaten their digital well-being. This article begins by critically evaluating the current approaches to digital well-being offered by ethicists of technology, NGOs, and social media corporations. My aim is to explain why digital well-being needs to be reimagined within a new conceptual paradigm. After this, I lay the foundations for such an alternative approach, one that shows how current digital well-being initiatives can (...) be designed in more insightful ways. This new conceptual framework aims to transform how philosophers of technology think about this topic, as well as offering social media corporations practical ways to design their technologies in ways that will improve the digital well-being of users.

This book brings together the relevant interdisciplinary and method elements needed to form a conceptual framework that is both pragmatic and rigorous. By using the best, and often the latest, work in thanatology, psychology, neuroscience, sociology, physics, philosophy and ethics, it develops a framework for understanding both what death is - which requires a great deal of time spent developing definitions of the various types of identity-in-the-moment and identity-over-time - and the values involved in death. This pragmatic framework answers questions (...) about why death is a form of loss; why we experience the emotional reactions, feelings and desires that we do; which of these reactions, feelings and desires are justified and which are not; if we can survive death and how; whether our deaths can harm us; and why and how we should prepare for death. Thanks to the pragmatic framework employed, the answers to the various questions are more likely to be accurate and acceptable than those with less rigorous scholarly underpinnings or which deal with utopian worlds..

The COVID-19 pandemic has catalysed what may soon become a permanent digital transition in the domains of work, education, medicine, and leisure. This transition has also precipitated a spike in concern regarding our digital well-being. Prominent lobbying groups, such as the Center for Humane Technology, have responded to this concern. In April 2020, the CHT has offered a set of ‘Digital Well-Being Guidelines during the COVID-19 Pandemic.’ These guidelines offer a rule-based approach to digital well-being, one which aims to mitigate (...) the effects of moving much of our lives online. The CHT’s guidelines follow much recent interest in digital well-being in the last decade. Ethicists of technology have recently argued that character-based strategies and redesigning of online architecture have the potential to promote the digital well-being of online technology users. In this article, I evaluate the CHT’s rule-based approach, comparing it with character-based strategies and approaches to redesigning online architecture. I argue that all these approaches have some merit, but that each needs to contribute to an integrated approach to digital well-being in order to surmount the challenges of a post-COVID world in which we may well spend much of our lives online.

A natural heme deficiency that exists in cells outside of the circulation broadly compromises the heme contents and functions of heme proteins in cells and tissues. Recently, we found that the signaling molecule, nitric oxide (NO), can trigger or repress the deployment of intracellular heme in a concentration‐dependent hormetic manner. This uncovers a new role for NO and sets the stage for it to shape numerous biological processes by controlling heme deployment and consequent heme protein functions in biology.

Value-sensitive design theorists propose that a range of values that should inform how future social robots are engineered. This article explores a new value: digital well-being, and proposes that the next generation of social robots should be designed to facilitate this value in those who use or come into contact with these machines. To do this, I explore how the morphology of social robots is closely connected to digital well-being. I argue that a key decision is whether social robots are (...) designed as embodied or disembodied. After exploring the merits of both approaches, I conclude that, on balance, there are persuasive reasons why disembodied social robots may well fare better with respect to the value of digital well-being.

Duncan Pritchard has recently defended a view he calls ‘epistemological disjunctivism’, largely inspired by John McDowell. I argue that Pritchard is right to associate the view with McDowell, and that McDowell’s ‘inference-blocking’ argument against the sceptic succeeds only if epistemological disjunctivism is accepted. However, Pritchard also recognises that epistemological disjunctivism appears to conflict with our belief that genuine and illusory experiences are indistinguishable (the ‘distinguishability problem’). Since the indistinguishability of experiences is the antecedent in the inference McDowell intends to block, (...) I suggest that his argument rests on an inconsistent set of premises. In support of this, I show that Pritchard’s response to the distinguishability problem is incompatible with the conclusion of the ‘inference-blocking’ argument, and that the response available in McDowell’s work relies on a mistaken conception of fallibility. Either McDowell must deny the sceptic’s premise that perceptual experiences are indistinguishable, or he must give up his conclusion that perceptual warrant can be indefeasible. (shrink)

A study involving purchasing managers was conducted to test specific Hunt-Vitell theoretical propositions concerning the determinants of managers' teleological evaluations. We extended the Hunt-Vitell model by developing a new integrative construct, namely the desirability of consequences to self versus others. We hypothesized that desirability of consequences affects teleological evaluations in that the more desirable the consequences of a particular action, the more likely managers evaluate that action positively. The results of the present study provided support for this hypothesis. Furthermore, we (...) extended the Hunt-Vitell model by developing a new integrative construct, namely the desirability of consequences of self versus others. We hypothesized that cognitive moral development moderates the relationship between the desirability of consequences of self versus others and teleological evaluation. The results failed to support this hypothesis. We explained the lack of support in terms of the level of aggregation of the data, the possibility of the confounding effect of respondents' sensitivity to ethical issues, and the possibility that deontological evaluations confounded the respondents' teleological judgments. Future research and managerial implications of the findings were also discussed. (shrink)

Points-based grading, though now traditional, faces powerful critiques: Such grading creates a low road to passing, it undermines motivation, it wastes time, and it causes stress. It creates an illusion of mathematical precision. It is unfriendly to necessary conditions for satisfactory performance. This paper defends the alternative of specifications grading. Specifications grading grades only on whether work meets a set of expectations for satisfactory performance, with the expectations set at a high but reachable level. With a high bar also comes (...) opportunities to revise unsatisfactory work. I summarize arguments from the literature in support of the system, but I also give account of my two-year experiment in philosophy courses with specifications grading. Compared with points-based grading, specifications grading appears to motivate students better and helps them learn more. I consider objections from both traditionalists and so-called ‘ungraders.’ The former hope to secure the benefits of specifications grading while still keeping points. The latter favor eliminating grading altogether. (shrink)

In his book Philosophie der Raum-Zeit-Lehre (1928) Reichenbach introduced the concept of universal force. Reichenbach's use of this concept was later severely criticized by Grünbaum. In this article it is argued that although Grünbaum's criticism is correct in an important respect, it misses part of Reichenbach's intentions. An attempt is made to clarify and defend Reichenbach's position, and to show that universal force is a useful notion in the physically important case of gravitation.

In lieu of an abstract, here is a brief excerpt of the content:The Awareness of the Natural World in Shinjin: Shinran's Concept of JinenDennis HirotaAttainment of Shinjin and TruthThe primary issue regarding knowledge that Shinran (1173-1263) treats in his writings concerns the commonplace, "natural" presupposition that it is constituted by an ego-subject relating itself to stable objects in the world. From his stance within Buddhist tradition, Shinran identifies the crucial problem as the human tendency toward the reification of both sides (...) of this dichotomy-resulting in an autonomous self and substantial things-with the consequent attachments fueling the afflictions ("blind passions") of habitual pain and conflict for oneself and others. The focus of Shinran's treatment of this basic Buddhist concern is the point of engagement with dharma or true reality. In this, he draws into the arena of religious faith the probing scrutiny of lingering attachments to self, even in the dedicated practitioner, that is fundamental to the critical attitude of Mahayana Buddhist tradition.My aim in taking up the issue of truth in my article "Shinran and Heidegger on Truth" in The Boundaries of Knowledge in Buddhism, Christianity, and Science 1 is to suggest a way of reading Shinran that both avoids a common pitfall that Shinran himself cautions against-an engagement with Pure Land teachings that adheres to the subject-object dichotomy of ordinary awareness-and opens up his vision to resonances with contemporary western thought, particularly continental philosophy. This latter concern is not to claim that Shinran adumbrates contemporary thought or is affirmed by resemblances, but rather seeks to cast light on compelling aspects of his thought not often treated in traditional Shin scholastics. There are, therefore, both therapeutic and constructive sides in my attempt to engage Martin Heidegger's (1889-1976) thought from a perspective rooted in Shinran's Buddhism.The pitfall in reading Shinran indicated in my article is crystallized in the assumption, prevalent in Western scholarship but also widely seen in Japan, that his Shin Buddhist path centers on a simple faith in the Pure Land teachings, with such faith understood as the subjective acceptance of the truth of doctrinal propositions. In [End Page 189] other words, it is commonly presupposed that Shin Buddhist tradition (what he terms jōdo shinshū, "the true essence of the Pure Land way") implicitly affirms the subject-object dichotomy. This difficulty is frequently compounded by formulations of the supposed tenets of belief that are heavily molded and colored by Protestant Christian notions of self, sin, eschatology, and atonement. It is impossible to take up such comparative theological issues here. 2 In a sense, I have sought in my article to circumvent a hasty assessment of conceptual equivalence by pointing out the possibility of an encompassing or prior dissonance.Since Shinran's concept of "attaining shinjin" (true entrusting, which is also the Buddha-mind given to the practitioner) is built on the endeavor to deconstruct the reification of this dichotomy in engagement with the Pure Land Buddhist path, the unconsciousness reinstatement of it in reading his writings can lead one to a thorough but easily accomplished misconstrual of his thought. My suggestion in my article is that consideration of the analogues in Heidegger's thought can help us see all this. Such comparison also appears to present a relatively untested avenue for Buddhist-Christian conversation, particularly in view of Heidegger's early indebtedness to Luther's "theology of the cross" and the notion of the "alien work of God" as the critical stripping away of attachments to human capacities (destructio in the "Heidelberg Disputation"), and also his approach to Paul's letters to the Thessalonians in The Phenomenology of Religious Life. 3 The keystone in such interreligious conversation remains, however, not simply human fallibility as subject or culpability as agent, but the persistent challenge to the subject-object dichotomy, which may form a locus of refractory difference between the religious traditions.The constructive side of the comparison concerns two general dimensions of Shinran's thought that are highlighted in an approach to his writings that might be called phenomenological. One includes a shift from a reading based on scriptural foundationalism and doctrinal reasoning to a dialogical reading, one attentive to Shinran's effort to... (shrink)

In the year 1471 a member of the Sorbonne, Guillaume Fichet, looking back on the history of what today we should call communication technology, divided it into three periods: antiquity , a subsequent period which we should identify as the Middle Ages , and a period just beginning . Just over five hundred years later an American scholar, Walter J. Ong, looking back on a longer historical span, divided it into orality, writing, printing, and electronic communications. No matter how much (...) these two figures may differ over details, they occupy a similar position: each stands at the start of a communications shift which has alerted him to changes in the past, and Ong claims explicitly that contrasts “between electronic media and print have sensitized us to the earlier contrast between writing and orality.” We do not have to go as far as Eric A. Havelock, who suggests that our new awareness can be precisely dated by a number of publications appearing in the annus mirabilis 1963 , in order to accept the general point that recent work has been stimulated by recent technology.

The significance of A. N. Whitehead’s contribution to 20th century metaphysics has become widely recognized. The focus on the novelty of his process ontology, however, has led to a view that isolates him from the mainstream of the tradition of Western philosophy. Hence, it is often overlooked that on the methodological level Whitehead is a pragmatist, whose much quoted indebtedness to William James is reflected in the project of his speculative metaphysics. A detailed analysis of the respective theories of truth (...) and knowledge in James and Whitehead illustrates their common methodological approach and allows us to assess the role of Whiteheadian thinking within the pragmatist tradition. James advances a form of epistemic conservatism that supplements the pragmatic idea of a concept’s cash-value with the demand for internal consistency. New beliefs have to fit in the totality of all previously accepted convictions in order to become accepted as true. James argues his case on three levels – a psychological, an epistemological and a pragmatic one – and develops a theory of truth that comprises an empirical and a rational dimension. Whitehead takes up this two-sided approach, but modifies the idea of genetic consistency into that of systematic coherence. The fundamental concepts of an ontological theory must not be isolated from each other to allow for a cosmology which is both rational and satisfies the pragmatic test of applicability. With the close relation of James and Whitehead in mind, the latter can be identified as the ‘missing link’ that bridges the gap between the so-called classical pragmatism and its more analytic versions as advanced by Quine, Lewis and Rescher.

The ArugmentThis essay answers a single question: what was Robert Hooke, the Royal Society's curator of experiments, doing in his well-known 1665 work,Micrographia?Hooke was articulating a “universal cure of the mind” capable of bringing about a “reformation in Philosophy,” a change in philosophy's interpretive practices and organization. The work explicated the interpretive and political foundations for a community of optical instrument users coextensive with the struggling Royal Society. Standard observational practices would overcome the problem of using nonstandard instruments, while inherent (...) inrepresentation– the interpretive practice championed in the text – were important theological and political meanings. Hooke's kind of experimental philosophy undermined the claims made by “atheists” and “enthusiasts” – the enemies of the restored church and state – while also producing useful knowledge. Equally important, Hooke modeled the community described inMicrographiaupon the classicalres publica, but his community made important concessions to Restoration political realities, especially the growing role of commercial or transactional relationships.

In Descartes’s reformulation of natural philosophy, two aspects of what came to be known as the mechanical philosophy were intimately joined: mechanism as an ontology of nature, according to which all natural things had only ‘mechanical’ properties; and mechanism as a method of explanation. One could, and many philosophers did, adopt mechanism as a method of explanation without adopting a mechanistic ontology. I examine two successors of Descartes who did just that, and one who did not. Giovanni Alfonso Borelli in (...) his De motu animalium and Charles Perrault in his Mécanique de animaux propose and argue for a variety of mechanical accounts of the operations of animals, in particular of their muscles. They reject, however, the Cartesian reduction of animal souls to mechanical forces; the principle of animal motion for them remains a non-mechanical soul. Pierre Sylvain Régis in his Cours entier de philosophie follows Descartes in taking the ‘physical cause’ of motion in animals to be the fermentation of blood in the heart, and thus denies animal souls any role in his physiology. That he can do so while taking over, sometimes word for word, Perrault’s accounts of animal motion shows that mechanistic explanation and mechanistic ontology could easily part company. (shrink)

Zygmunt Bauman has used his `outsider' position to explore the defining boundaries of our world and help shape a discourse which allows communication across these boundaries. In this spirit he has investigated: sociology and culture; capitalism, socialism and class; and modernity and postmodernity. Bauman has argued for an emancipatory sociology which takes full account of what ought and ought not to be, what human beings hope for and fear, and the need to give people intellectual tools to make use of (...) their freedom. Applying the strategy of the `hermeneutic circle', he has examined capitalist and socialist regimes from a range of vantage points. He has also identified the challenges we all now face as inhabitants of the half-ruined structures created by modernity's failed ambitions. Bauman has confronted these challenges in the last decade by focusing on the evils of modern bureaucracy as epitomized by the Holocaust, the inescapability of each individual's responsibility for his or her own moral choices, and the potential for an open and self-critical dialogue between sociologists and their fellow citizens.
