Intercellular signaling plays an important role in spatially regulated developmental processes. Myxococcus xanthus C signal transmission during fruiting body formation requires motile, densely packed, well aligned cells. tThe fruiting body consists of two domains: an outer domain which has densely packed, well aligned, motile cells: and an inner domain of more loosely packed, non‐motile, sporulating cells. The two domains are characterized by different patterns of C‐dependent gene expression, which begins in the outer domain where C‐signaling is most efficient, and reaches (...) its maximum in the inner domain. These domains may be maintained by a dynamic mechanism which relies on passive transport of the sporulating cells from the outer domain, where sporulation is initiated, to the inner domain by the motile cells in the outer domain.

This is an English translation of Schelling's Ideas for a Philosophy of Nature (first published in 1797 and revised in 1803), one of the most significant works in the German tradition of philosophy of nature and early nineteenth-century philosophy of science. It stands in opposition to the Newtonian picture of matter as constituted by inert, impenetrable particles, and argues instead for matter as an equilibrium of active forces that engage in dynamic polar opposition to one another. In the revisions of (...) 1803 Schelling incorporated this dialectical view into a neo-Platonic conception of an original unity divided upon itself. The text is of more than simply historical interest: its daring and original vision of nature, philosophy, and empirical science will prove absorbing reading for all philosophers concerned with post-Kantian German idealism, for scholars of German Romanticism, and for historians of science.

In Search of a Political Philosophy is an analysis of the three democratic `isms'--conservatism, liberalism, and socialism--and of the distinct nature of the all-consuming ideology of Marxist communism. W. J. Stankiewicz is concerned with the conscious and unconscious assumptions of the proponents and followers of each ideology, and those of their theoreticians and critics. Stankiewicz examines the norms by which political ideologies are characterized, and discusses which of these are given precedence. He provides an analysis of how each ideology views (...) such issues as freedom and restraint, responsibility, equality, justice, power, authority, property, human nature and happiness. He also examines the areas of ideological contiguity and mutual influences, the sources of ideological incomprehension in our society, and the forces that split Western societies. In Search of a Political Philosophy takes issue with the positions of some of our leading political theorists and represents an original contribution to political philosophy in its own right. It makes a stimulating and challenging contribution to the areas of politics, political philosophy, ethics, political and social theory, the history of political thought, and the history of ideas.

W. J. Mander presents the first ever synoptic history of British Idealism, the school of thought which dominated English-language philosophy from the 1860s to the early 20th century. He restores to its proper place this neglected period of philosophy, introducing the exponents of Idealism and explaining its distinctive concepts and doctrines.

There exist important deductive systems, such as the non-normal modal logics, that are not proper subjects of classical algebraic logic in the sense that their metatheory cannot be reduced to the equational metatheory of any particular class of algebras. Nevertheless, most of these systems are amenable to the methods of universal algebra when applied to the matrix models of the system. In the present paper we consider a wide class of deductive systems of this kind called protoalgebraic logics. These include (...) almost all (non-pathological) systems of prepositional logic that have occurred in the literature. The relationship between the metatheory of a protoalgebraic logic and its matrix models is studied. The following results are obtained for any finite matrix model U of a filter-distributive protoalgebraic logic : (I) The extension U of is finitely axiomatized (provided has only finitely many inference rules); (II) U has only finitely many extensions.

What precisely, W. J. T. Mitchell asks, are pictures (and theories of pictures) doing now, in the late twentieth century, when the power of the visual is said to be greater than ever before, and the "pictorial turn" supplants the "linguistic turn" in the study of culture? This book by one of America's leading theorists of visual representation offers a rich account of the interplay between the visible and the readable across culture, from literature to visual art to the mass (...) media.

This paper is based on Lectures 1, 2 and 4 in the series of ten lectures titled “Algebraic Structures for Logic” that Professor Blok and I presented at the Twenty Third Holiday Mathematics Symposium held at New Mexico State University in Las Cruces, New Mexico, January 8-12, 1999. These three lectures presented a new approach to the algebraization of deductive systems, and after the symposium we made plans to publish a joint paper, to be written by Blok, further developing these (...) ideas. That project was still incomplete when Blok died. In fact, there is no indication that he had prepared a draft of the paper, and we do not know what new material he intended to include. I am therefore not in a position to complete the project as he had envisioned it. So, I have settled for the more limited objective of presenting the material from the three lectures, leaving to others the task of adapting the techniques used there to more general situations.

W. J. Mander provides a brief introduction to and critical assessment of the thought of the greatest of the British Idealist philosophers, F. H. Bradley (1846-1924), whose work has been largely neglected in this century. After a general introduction to Bradley's metaphysics and its logical foundations, Mander shows that much of Bradley's philosophy has been seriously misunderstood. Mander argues that any adequate treatment of Bradley's thought must take full account of his unique dual inheritance from the traditions of British empiricism (...) and Hegelian rationalism. The scholarship of recent years is assessed, and new interpretations are offered of Bradley's views about truth, predication, and relations, and of his arguments for idealism. (shrink)

This is the first full assessment of British philosophy in the 19th century. Specially written essays by leading experts explore the work of the key thinkers of this remarkable period in intellectual history, covering logic and scientific method, metaphysics, religion, positivism, the impact of Darwin, and ethical, social, and political theory.

"This book contains ideas to develop interdisciplinary and transdisciplinary views on economy and society. It aims to disseminate heterodox ideas on various subjects related to economics and global society. The book is organised in six parts. Part 1 contains the key lectures of Backhaus on the concept of state sciences and of Klamer on the importance of culture for economics. Parts 2- 6 contain successively contributions in the areas of economic paradigms and theories, population and society, corporate issues, environment, and (...) international relations. Examples of the content are: - the changes of family life cycles due to the rise of non-traditional households; - subjective and objective inflation rates after the introduction of the Euro; - the economics of genetic engineering; - the contribution of foreign direct investment to the economic development of host countries; - the inaccuracy of economic models applied in places characterized by extreme income disparities; - the improvement of political and corporate governance; - evolutionary thinking and emission trading; - freedom and order in the European Union; - the reform of social policy in Europe. The book provides interesting creative multi-disciplinary ideas with respect to various topical issues concerning the contemporary global society. It is highly recommended for economists and social scientists in search of broad views on social science and society.". (shrink)

Modal logics are studied in their algebraic disguise of varieties of so-called modal algebras. This enables us to apply strong results of a universal algebraic nature, notably those obtained by B. Jonsson. It is shown that the degree of incompleteness with respect to Kripke semantics of any modal logic containing the axiom □ p → p or containing an axiom of the form $\square^mp \leftrightarrow\square^{m + 1}p$ for some natural number m is 2 ℵ 0 . Furthermore, we show that (...) there exists an immediate predecessor of classical logic (axiomatized by $p \leftrightarrow \square p$ ) which is not characterized by any finite algebra. The existence of modal logics having 2 ℵ 0 immediate predecessors is established. In contrast with these results we prove that the lattice of extensions of S4 behaves much better: a logic extending S4 is characterized by a finite algebra iff it has finitely many extensions and any such logic has only finitely many immediate predecessors, all of which are characterized by a finite algebra.

This paper argues that a strong thesis of divine providence, whereby God is understood as in complete control of all things, entails pantheism, the thesis that the universe is not ontologically distinct from God. In normal discourse, we distinguish a plan from, on the one hand, the state of affairs which realizes that plan—its execution or expression—and, on the other hand, the person or group whose plan it is. However, with respect to an omnipotent God who displays complete providence, neither (...) of these two distinctions holds. We cannot separate person from plan, or plan from world, and in consequence, neither can we separate person from world, ergo pantheism. Accordingly, the argument of this paper comes in two parts maintaining, first, the impossibility of distinguishing between God’s plan and its execution and, second, the impossibility of distinguishing God himself from his plan.

W. J. Mander examines the nature of idealist ethics, that is to say, the form and content of ethical belief most typically adopted by philosophical idealists. His inquiry has two aims. The first is historical: from the record of past philosophy, Mander demonstrates that there exists a discernible idealist approach to moral philosophy; a tradition of 'idealist ethics', and examines its characteristic marks and varieties. The second aim is apologetic. He argues that such idealist ethics offers an attractive way of (...) looking at moral questions and that it has much to contribute to contemporary discussion. In particular he argues that Idealist ethics have the power to cut through the sterile opposition between moral realism and moral anti-realism. To be an idealist is precisely to hold that the universe is so constituted that things are real if and only if they are ideal; to hold that uncovering in something the work of mind makes it more not less significant.

We study modal logics in the setting of varieties of modal algebras. Any variety of modal algebras generated by a finite algebra — such, a variety is called tabular — has only finitely many subvarieties, i.e. is of finite height. The converse does not hold in general. It is shown that the converse does hold in the lattice of varieties of K4-algebras. Hence the lower part of this lattice consists of tabular varieties only. We proceed to show that there is (...) a continuum of pretabular varieties of K4-algebras — those are the non-tabular varieties all of whose proper subvarieties are tabular — in contrast with Maksimova's result that there are only five pretabular varieties of S4-algebras.

In this paper I argue that Wittgenstein is correct when he says of the Standard Metre stick that we can neither say that it is or is not a metre in length – despite what our intuitions may tell us to the contrary. Specifically, the paper deals with Kripke's criticism of Wittgenstein's claim in Naming And Necessity and with Salmon's attempt to arbitrate between the two views. I conclude that, not only is Wittgenstein correct, but that both Kripke and Salmon (...) (and possibly the majority of philosophers) simply do not understand the concept of measurement. (shrink)

In this study, W. J. Waluchow argues that debates between defenders and critics of constitutional bills of rights presuppose that constitutions are more or less rigid entities. Within such a conception, constitutions aspire to establish stable, fixed points of agreement and pre-commitment, which defenders consider to be possible and desirable, while critics deem impossible and undesirable. Drawing on reflections about the nature of law, constitutions, the common law, and what it is to be a democratic representative, Waluchow urges a different (...) theory of bills of rights that is flexible and adaptable. Adopting such a theory enables one not only to answer to critics' most serious challenges, but also to appreciate the role that a bill of rights, interpreted and enforced by unelected judges, can sensibly play in a constitutional democracy.

Russian Marxism is the outcome of two distinct traditions, namely, nineteenth-century Russian radicalism and Western European Marxism. In this paper I shall briefly trace its descent from these traditions and try to distinguish those features of it which differentiate it both from the older radicalism and from the Marxism of Marx and Engels. I shall deal in turn with three main topics, the nineteenth-century radical tradition, early Russian Marxism, and finally, Leninism.
