The technique of covers is now well established in semigroup theory. The idea is, given a semigroup S, to find a semigroup having a better understood structure than that of S, and an onto morphism of a specific kind from to S. With the right conditions on , the behaviour of S is closely linked to that of . If S is finite one aims to choose a finite . The celebrated results for inverse semigroups of McAlister in the 1970s (...) form the flagship of this theory.Weakly left quasi-ample semigroups form a quasivariety (of algebras of type(2, 1)), properly containing the classes of groups, and of inverse, left ample, and weakly left ample semigroups. We show how the existence of finite proper covers for semigroups in this quasivariety is a consequence of Ashs powerful theorem for pointlike sets. Our approach is to obtain a cover of a weakly left quasi-ample semigroup S as a subalgebra of S × G, where G is a group. It follows immediately from the fact that weakly left quasi-ample semigroups form a quasivariety, that is weakly left quasi-ample. We can then specialise our covering results to the quasivarieties of weakly left ample, and left ample semigroups. The latter have natural representations as (2, 1)-subalgebras of partial (one-one) transformations, where the unary operation takes a transformation to the identity map in the domain of . In the final part of this paper we consider representations of weakly left quasi-ample semigroups. (shrink)

Written in political exile during the Second World War and first published in 1945, Karl Popper's The Open Society and Its Enemiesis one of the most influential books of the twentieth century. Hailed by Bertrand Russell as a 'vigorous and profound defence of democracy', its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems. Popper's highly accessible style, his erudite and lucid explanations of the thought of great philosophers (...) and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of The Open Society and Its Enemies, and for why it demands to be read both today and in years to come. This is the second of two volumes of The Open Society and Its Enemies. (shrink)

Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside _The Open Society and Its Enemies_ as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

First published in French, Marx's The Poverty of Philosophy (1847) was composed during his years in Brussels, when he was developing his economic views and, through confrontations with the chief leaders of the working-class movement, establishing his intellectual standing. In this classic work, which laid the foundation of ideas later developed in Capital, Marx polemicized against then premier French socialist, Pierre-Joseph Proudhon. Proudhon wanted to unite the best features of such contraries as competition and monopoly. He hoped to save the (...) good features of economic institutions while eliminating the bad. Marx, however, declared that no equilibrium was possible between the antagonisms in any given economic system. Social structures were transient historical forms determined by the productive forces: "The handmill gives you society with the feudal lord; the stream mill, society with the industrial capitalist.".

This chapter suggests how certain problematic claims of pantheism might be made more intelligible. It shows, first, that some pantheistic God-talk is comparable to talk involving mass terms; treating “God” as a mass term affords us a way of understanding, for example, how parts can seemingly be identified with the wholes of which they are the parts, as per the claim that “God is everything and everything is God”. This chapter then goes on to describe a contemporary variant of panpsychism, (...) a variant speculatively predicated on the affinity between intentional states and causal dispositions. This allows for a conception of the world as God’s brain, cashed out in terms of a “panintentionalism” that admits of various organizational possibilities for causal dispositional states, comparable to the organization of intentional states in human brains.

Karl Jaspers gehört zu den Ziehvätern der Psychopathologie, einer der Grundlagenwissenschaften der Psychiatrie. In diesem Zusammenhang wird gemeinhin auf sein systematisches Lehrbuch verwiesen, die Allgemeine Psychopathologie von 1913. Die wesentlichen Züge seiner Methodologie und den Gegenstand der neuen Wissenschaft fixierte Jaspers jedoch schon in den hier versammelten Arbeiten, die zwischen 1909 und 1913 erschienen: Seine Kritik am dominanten Reduktionismus und an der damals noch jungen Psychoanalyse sind in diesen Texten bereits gültig formuliert, ebenso - und nicht zuletzt - die (...) Dichotomie zwischen Erklären und Verstehen. Neben der Dissertation “Heimweh und Verbrechen” enthält der vorliegende Band unter anderem den bahnbrechenden und wirkungsvollen Aufsatz “Die phänomenologische Forschungsrichtung in der Psychiatrie” sowie die bis heute kontrovers diskutierte Abhandlung “Kausale und 'verständliche' Zusammenhänge zwischen Schicksal und Psychose bei der Dementia praecox (Schizophrenie)”. Der Kommentar verortet die einzelnen Beiträge sowohl im wissenschaftshistorischen als auch im werkgeschichtlichen Kontext. (Quelle: buchhandel.de). (shrink)

In this article I offer an opinionated overview of the central elements of Kant’s philosophical methodology during the critical period. I begin with a brief characterization of how Kant conceives of the aims of human inquiry – focusing on the idea that inquiry ideally aims at not just cognition (Erkenntnis), but also the more demanding cognitive achievements that Kant labels insight (Einsehen) and comprehension (Begreifen). Then I explore the implications of this picture for philosophy — emphasizing Kant’s distinction between critical (...) and doctrinal phases of philosophical inquiry, with the first of these playing both a negative and a positive role with respect to the second. Then, I will argue that this positive role is possible, according to Kant, only insofar as philosophy follows what I call a “capacities-first” methodology – that is, one that treats basic cognitive capacities (such as reason) and their self-conscious activities as fundamental (in both a cognitive sense and in an explanatory sense) for the sort of philosophy human beings are capable of. It is this methodology, I will argue, that allows Kant to introduce the first principles that philosophy in its doctrinal phase requires in a manner that is neither arbitrary nor (at least obviously) incompatible with Kant’s own critical restrictions on cognition. I conclude by discussing some of the implications of this methodological picture – including the methodological significance of self-consciousness and regressive or “transcendental” arguments, Kant’s distinction between analytic and synthetic methods in philosophy, and Kant’s conception of reason as autonomous.

Karl Pfeifer attempts to present a coherent view of panentheism that eschews Pickwickian senses of “in” and aligns itself with, and builds upon, familiar diagrammed portrayals of panentheism. The account is accordingly spatial-locative and moreover accepts the proposal of R.T. Mullins that absolute space and time be regarded as attributes of God. In addition, however, it argues that a substantive parthood relation between the world and God is required. Pfeifer’s preferred version of panpsychism, viz. panintentionalism, is thrown into the (...) mix as an optional add-on. On this account, God is conceived of as a “spiritual field” whose nature can be made more intelligible by regarding “God” as having a mass-noun sense in some contexts. Pfeifer closes with the suggestion that we look to topology and mereology for further development of the position outlined in his paper. (shrink)

Karl Hahn, Jahrgang 1937, war bis zu seiner Emeritierung im Jahr 2003 Professor für Politische Theorie und Ideengeschichte an der Westfälischen Wilhelms-Universität Münster. Hierbei hat er die Klassiker der abendländischen Geistesgeschichte nicht in einem kanonisch-schematischen Profil gelehrt, sondern die jeweiligen Themen und Theoreme mit lebensfüllender Leidenschaft vermittelt. Seine Vorlesungen und Seminare an der Universität zeugen, wie auch seine Vorträge und Tagungsbeiträge, von einem streitbaren Geist, der stets auch um die aktualisierende Bezugnahme bemüht war. Stets hat er pointiert Stellung bezogen, (...) auch gegen den Mainstream des Faches, das er kritisch hinterfragt hat. Ob Platon, Fichte oder auch Simone Weil: Bei Karl Hahn stehen philosophische Überlegungen für eine Suche nach der Vollendung des Daseins in seinen unendlich vielen und offenen Aussagemöglichkeiten. Hahns großes Lebensthema war und ist hierbei das tragische Element des menschlichen Wesens, dessen Kleinheit und Begrenztheit angesichts der großen Fragen der menschlichen Existenz. Das hat er seinen Studierenden mit auf den Weg gegeben. Und auch den Kolleginnen und Kollegen, die bereit waren, zuzuhören. Mit dem vorliegenden Band wird der Wissenschaftler zum Anlass seines 80. Geburtstages geehrt, der seine Verdienste nicht in der flüchtigen Wertschätzung des Feuilletons, sondern grundsätzlich im Diskurs der Seminarräume und Kongressveranstaltungen erworben hat. (shrink)

With respect to the topic of “powers and abilities,” most readers will associate David Hume with his multi-pronged critique of traditional attempts to make robust explanatory use of those notions in a philosophical or scientific context. But Hume’s own philosophy is also structured around the attribution to human beings of a variety of basic faculties or mental powers – such as the reason and the imagination, or the various powers involved in Hume’s account of im- pressions of reflection and the (...) passions. Indeed, there is a clear case to be made that, despite his deflationary account of our concept of power, Hume continues to treat certain basic powers or faculties as forming the explanatory bedrock for his new “science of man”. In this essay, I will discuss how this apparent conflict between the “critical” (if not outright skeptical) and “constructive” aspects of Hume’s discussion of powers and abilities is best resolved – with special attention to the question of how this illuminates Hume’s place in the development of early modern conceptions of the proper method for philosophy.

Ein Pladoyer fur die Verstandigung zwischen den Religionen Mit dem Glauben an Offenbarung hat Jaspers sich schon sehr fruh auseinandergesetzt. Der Offenbarungsglaube bildete das Gegenuber, angesichts dessen ihm bewusst wurde, was er selbst den philosophischen Glauben nannte: einen Glauben an Transzendenz jenseits konfessioneller Gebundenheit, der, so die Hoffnung, imstande war, den Frieden zwischen den Religionen herzustellen, ohne bewahrte religiose Bindungen aufzulosen. Dennoch sollte es Jahrzehnte dauern, bis Jaspers das Verhaltnis zwischen philosophischem Glauben und Offenbarungsglauben in drei einschlagigen Publikationen zum Thema (...) machte. Band 13 der KJG enthalt als zentralen Text das Alterswerk 'Der philosophische Glaube angesichts der Offenbarung' (1962/63). Zur Seite gestellt sind ihm der Festschriftbeitrag 'Der philosophische Glaube angesichts der christlichen Offenbarung' (1960), der aus dem das genannte Buch hervorgegangen ist, sowie das mit Heinz Zahrnt gefuhrte Gesprach 'Philosophie und Offenbarungsglaube' (1963).

Main description:?"Aus den zahllosen Abhandlungen zum Werk Friedrich Nietzsche ragt die Gesamtdarstellung von Karl Jaspers immer noch als einzigartige Leistung heraus. Nietzsche wird als 'großer Philosoph' historisch und systematisch umfassend vorgestellt. Von unverminderter Aktualität ist das souveräne, auf alle verfügbaren medizinischen Daten gestützte Urteil des Psychiaters Jaspers über Nietzsches Krankheit." Prof. Dr. Volker Gerhardt.

Auch als originar politischer Denker ist Karl Jaspers reich an Einsichten: Ausgehend vom Ethos der Freiheit jedes Einzelnen richtet er seinen Blick auf die konkrete politische Gestaltung einer Freiheitsordnung. Dabei steht fur ihn im Hinblick auf die noch junge Bundesrepublik die Selbsterziehung in Freiheit im Zentrum seiner oft mahnenden Worte. Ganz im sokratischen Sinne fordert er intellektuelle Redlichkeit und politische Wahrhaftigkeit ein, um den beiden grossen Gegenwartsherausforderungen gewachsen zu sein: einer atomwaffenbestuckten Welt, die sich jederzeit selbst ausloschen kann, und (...) dem modernen Totalitarismus, der in seiner Verherrlichung des Antipolitischen allen politischen Ordnungsbestrebungen die Vernichtung androht. Jeder Frieden, der mehr ist als die Friedhofsruhe eines Waffenstillstands, grundet fur Jaspers in der politischen Freiheit handelnder Burgerinnen und Burger, die gemeinsam Sorge fur die Integritat ihres politischen Gemeinwesens tragen.

This book explores the main stages and key concepts in the development of Kant's critical philosophy, from the early 1760s to the 1790s. Karl Ameriks provides a detailed and concise account of the main ways in which the later critical works provide a plausible defense of the conception of humanity's fundamental end that Kant turned to after reading Rousseau in the 1760s. Separate essays are devoted to each of the three Critiques, as well as to earlier notes and lectures (...) and several of Kant's later writings on history and religion. A final section devotes three chapters to post-Kantian developments in German Romanticism, accounts of tragedy up through Nietzsche, and contemporary philosophy. The theme of an elliptical path is shown to be relevant to these writers as well as to many aspects of Kant's own life and work. The topics of the book include fundamental issues in epistemology and metaphysics, with a new defense of the Amerik's 'moderate' interpretation of transcendental idealism. (shrink)

Czech translation of Karl Jaspers’ Über meine Philosophie.

Over Plato's Academy in ancient Athens, it is said, hung a sign: "Let no one ignorant of geometry enter here." Plato thought no one could do philosophy without also doing mathematics. In The Waltz of Reason, mathematician and philosopher Karl Sigmund shows us why. Charting an epic story spanning millennia and continents, Sigmund shows that philosophy and mathematics are inextricably intertwined, mutual partners in a reeling search for truth. Beginning with-appropriately enough-geometry, Sigmund explores the power and beauty of numbers (...) and logic, and then shows how those ideas laid the ground work for everything from the theory of a fair election, to modern conceptions of governance, cooperation, morality, and even of reason itself. Did you know, for example, that John Locke, author of some of the most important texts in the Western theory of government, was motivated in his work by his study of geometry? Or, that Locke was actually terrible at geometry, a seventeenth-century mathematical laughingstock? He was, a fact that might want us to think again about the logic of his life's work. And Locke wasn't the only one! Sigmund reveals how many of our modern ideas about what is true and what is reasonable are based on similarly shaky grounds. The economists and other thinkers who promulgated game theory, classical economics, and behavioral economics-the basis of so much in modern life-were not necessarily good at either math or philosophy, or both. The result is a remarkable book: accessible, funny, and wise, it tells an engrossing history of ideas that spins as dizzyingly and beautifully as a ballroom full of expert dancers. But it doesn't just celebrate the past. Instead, by making all these great ideas accessible to all, The Waltz of Reason empowers as it entertains, giving each of us the tools to ask, what do we know, how do we know it, and what do we want to do, with all these ideas?
