This book examines the origins and subsequent evolution of multicellularity. The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve.

Overview The evolution of multicellularity raises questions regarding genomic and developmental commonalities and discordances, selective advantages and disadvantages, physical determinants of development, and the origins of morphological novelties. It also represents a change in the definition of individuality, because a new organism emerges from interactions among single cells. This volume considers these and other questions, with contributions that explore the origins and consequences of the evolution of multicellularity, addressing a range of topics, organisms, and experimental protocols. Each section focuses on (...) selected topics or particular lineages that present a significant insight or challenge. The contributors consider the fossil record of the paleontological circumstances in which animal multicellularity evolved; cooptation, recurrent patterns, modularity, and plausible pathways for multicellular evolution in plants; theoretical approaches to the amoebozoa and fungi (cellular slime molds having long provided a robust model system for exploring the evolution of multicellularity), plants, and animals; genomic toolkits of metazoan multicellularity; and philosophical aspects of the meaning of individuality in light of multicellular evolution.

William C. Gentry was both an academic philosopher, perfectly willing to engage in the philosophical 'conversations' of the written word and, more importantly, a true philosopher, in the Platonic and Socratic style. Engaging with those around him in discourse, in live conversations, which are the vehicle of actual philosophical inquiry and discovery. These essays are the product of those conversations. Gentry's thoughts consisted of investigations into the deepest and most profound questions of human nature, ethics, and knowledge. This volume (...) is a tribute both to his role as a teacher and philosopher. As a teacher, friend, and colleague, Gentry was the epitome of the philosopher: questioning, exploring, critiquing, discovering. (shrink)

In a discussion-note in Mind, Father P. M. Farrell, O.P., gave an account, in what he admitted to be an embarrassingly brief compass, of the Thomist doctrine concerning evil. There is one sentence in this discussion which at first glance appears paradoxical. Father Farrell has been arguing that a universe containing ‘corruptible good’ as well as incorruptible is better than one containing ‘incorruptible good’ only. He continues: ‘If, however, they are to manifest this corruptible good, they must be corruptible and (...) they must sometimes corrupt.’ The final words, despite Father Farrell's italics, strike one as expressing, not a self-evident truth, but a non sequitur. The fact that I am capable of committing murder does not entail that I will at some time commit it. It is not immediately obvious that a similar entailment holds in the case of corruption and corruptibility. (shrink)

Two strategies for using a model as “null” are distinguished. Null modeling evaluates whether a process is causally responsible for a pattern by testing it against a null model. Baseline modeling measures the relative significance of various processes responsible for a pattern by detecting deviations from a baseline model. When these strategies are conflated, models are illegitimately privileged as accepted until rejected. I illustrate this using the neutral theory of ecology and draw general lessons from this case. First, scientists cannot (...) draw certain conclusions using null modeling. Second, these conclusions follow using baseline modeling, but doing so requires more evidence. (shrink)

This book introduces the work of an important medieval Islamic philosopher who is little known outside the Persian world. Afdal al-Din Kashani was a contemporary of a number of important Muslim thinkers, including Averroes and Ibn al-Arabi. Kashani did not write for advanced students of philosophy but rather for beginners. In the main body of his work, he offers especially clear and insightful expositions of various philosophical positions, making him an invaluable resource for those who would like to learn the (...) basic principles and arguments of this philosophical tradition but do not have a strong background in philosophy. Here, Chittick uses Kashani and his work to introduce the basic issues and arguments of Islamic philosophy to modern readers. (shrink)

William C. Dell teaches us to move our imaginations beyond the bounds of ordinary space time into the realm of eternal Zen consciousness, of the endless process of Zen deconstructing.

The use of multiple means of determination to “triangulate” on the existence and character of a common phenomenon, object, or result has had a long tradition in science but has seldom been a matter of primary focus. As with many traditions, it is traceable to Aristotle, who valued having multiple explanations of a phenomenon, and it may also be involved in his distinction between special objects of sense and common sensibles. It is implicit though not emphasized in the distinction between (...) primary and secondary qualities from Galileo onward. It is arguably one of several conceptions involved in Whewell’s method of the “consilience of inductions” (Laudan 1971) and is to be found in several places in Peirce. (From M. Brewer and B. Collins, eds., (1981); Scientific Inquiry in the Social Sciences (a festschrift for Donald T. Campbell), San Francisco: Jossey-Bass, pp. 123–162.). (shrink)

Willard van Orman Quine once said that he had a preference for a desert ontology. This was in an earlier day when concerns with logical structure and ontological simplicity reigned supreme. Ontological genocide was practiced upon whole classes of upper-level or ‘derivative’ entities in the name of elegance, and we were secure in the belief that one strayed irremediably into the realm of conceptual confusion and possible error the further one got from ontic fundamentalism. In those days, one paid more (...) attention to generic worries about possible errors than to actual errors derived from distancing oneself too far from the nitty-gritty details of actual theory, actual inferences from actual data, the actual conditions under which we posited and detected entities, calibrated and ‘burned in’ instruments, identified and rejected artifacts, debugged programs and procedures, explained the mechanisms behind regularities, judged correlations to be spurious, and in general, to the real complexities and richness of actual scientific practice.

“The object of this book,” writes William C. Dowling in his preface, “is to make the key concepts of Paul Ricoeur’s _Time and Narrative_ available to readers who might have felt bewildered by the twists and turns of its argument.” The sources of puzzlement are, he notes, many. For some, it is Ricoeur’s famously indirect style of presentation, in which the polarities of argument and exegesis seem so often and so suddenly to have reversed themselves. For others, it is (...) the extraordinary intellectual range of Ricoeur’s argument, drawing on traditions as distant from each other as Heideggerian existentialism, French structuralism, and Anglo-American analytic philosophy. Yet beneath the labyrinthian surface of Ricoeur’s _Temps et récit_, Dowling reveals a single extended argument that, though developed unsystematically, is meant to be understood in systematic terms. __Ricoeur on Time and Narrative_ _presents that argument in clear and concise terms, in a way that will be enlightening both to readers new to Ricoeur and those who may have felt themselves adrift in the complexities of _Temps et récit,_ Ricoeur’s last major philosophical work. Dowling divides his discussion into six chapters, all closely involved with specific arguments in _Temps et récit_: on mimesis, time, narrativity, semantics of action, poetics of history, and poetics of fiction. Additionally, Dowling provides a preface that lays out the French intellectual context of Ricoeur's philosophical method. An appendix presents his English translation of a personal interview in which Ricoeur, having completed _Time and Narrative, _looks back over his long career as an internationally renowned philosopher. __Ricoeur on Time and Narrative___ _communicates to readers the intellectual excitement of following Ricoeur’s dismantling of established theories and arguments—Aristotle and Augustine and Husserl on time, Frye and Greimas on narrative structure, Arthur Danto and Louis O. Mink on the nature of historical explanation—while coming to see how, under the pressure of Ricoeur’s analysis, these ideas are reconstituted and revealed in a new set of relations to one another. "The scholarship in William C. Dowling's __Ricoeur on Time and Narrative____ __is impeccable; Dowling knows Ricoeur inside out. He highlights Ricoeur's most important arguments, presents them in a limpid, concise language, and links them to the relevant nineteenth- and twentieth-century philosophical developments. Dowling's book provides us with a lucid, intelligible version of Ricoeur's major work, one that will be of considerable significance to philosophers, historians, and literary theorists." —_Thomas Pavel, Gordon J. Laing Distinguished Service Professor of French Literature, and the Committee on Social Thought, University of Chicago_ "William C. Dowling's __Ricoeur on Time and Narrative___ _is a subtle and remarkably well-sustained piece of work. It provides a detailed introduction to a major work of philosophy and narrative theory—already a considerable achievement, given the difficulty of Ricoeur's text. However, Dowling also shows us, sometimes explicitly, sometimes simply through the way he conducts his argument, why we should bother with Ricoeur—what we have to gain from knowing him better than we do, however well we may think we know him." —_Michael Wood, Charles Barnwell Straut Class of 1923 Professor of English and Comparative Literature, Princeton University _.

After an initial discussion of the character of interdisciplinary linkages between complex disciplines, I consider an area with confluences of many diverse disciplines—the study of cultural evolution. This must embrace not only the traditional biological sciences, but also the multiple often warring disciplines of the human sciences. This interdisciplinary articulation is in its early stages compared, e.g., to that of evolutionary biology or evolutionary developmental biology, and I try to lay out major axes along which its articulation should plausibly occur, (...) given the relevant causal processes acting at different levels. One cannot have an adequate account of cultural evolution without recognizing a central role for cognitive and social development and the social and cultural organizations and institutions and artifactual tools and infrastructure that support and structure these developmental processes. These induce a population structure that mediates the transmission, expression, and elaboration of culture, and in particular the different ways in which they scaffold learning and the development and articulation of complex skills. I consider how these elements should articulate the disciplines that tend to focus separately on them. Intentions and the market are not explicitly included in this account, and I consider ways in which these perspectives might enter. (shrink)

The corporation's social role is usually presented as a cultural phenomenon in which the corporation learns socially acceptable behaviors through voluntary social responsibility, government regulations/public policies, and/or acceptance of ethics principles. This article presents an alternative view of corporationcommunity relations as a natural phenomenon based on complexity-chaos theory and a biological-physical conception of corporate values. Corporation and community are depicted as interacting nonlinear adaptive systems having unpredictable futures, the corporate social role is depicted as largely indeterminate, and competing values are (...) depicted as key factors driving change in corporationcommunity linkages. Normative duties of corporate and community leaders are described. (shrink)

Most philosophical accounts of emergence are incompatible with reduction. Most scientists regard a system property as emergent relative to properties of its parts if it depends upon their mode of organization-a view consistent with reduction. Emergence is a failure of aggregativity, in which ``the whole is nothing more than the sum of its parts''. Aggregativity requires four conditions, giving powerful tools for analyzing modes of organization. Differently met for different decompositions of the system, and in different degrees, the structural conditions (...) can provide evaluation criteria for choosing decompositions, ``natural kinds'', and detecting functional localization fallacies, approximations, and various biases of vulgar reductionisms. This analysis of emergence and use of these conditions as heuristics is consistent with a broader reductionistic methodology. (shrink)

Levin and Schnorr (independently) introduced the monotone complexity, Km(α), of a binary string α. We use monotone complexity to define the relative complexity (or relative randomness) of reals. We define a partial ordering ≤Km on 2ω by α ≤Km β iff there is a constant c such that Km(α ↾ n) ≤ Km(β ↾ n) + c for all n. The monotone degree of α is the set of all β such that α ≤Km β and β ≤Km α. We (...) show the monotone degrees contain an antichain of size 2N0, a countable dense linear ordering (of degrees of cardinality 2N0), and a minimal pair. Downey, Hirschfeldt, LaForte, Nies and others have studied a similar structure, the K -degrees, where K is the prefix-free Kolmogorov complexity. A minimal pair of K -degrees was constructed by Csima and Montalbán. Of particular interest are the noncomputable trivial reals, first constructed by Solovay. We define a real to be (Km, K)-trivial if for some constant c, Km(α ↾ n) ≤ K(n)+c for all n. It is not known whether there is a Km-minimal real, but we show that any such real must be (Km, K)-trivial. Finally, we consider the monotone degrees of the computably enumerable (c.e.) and strongly computably enumerable (s.c.e.) reals. We show there is no minimal c.e. monotone degree and that Solovay reducibility does not imply monotone reducibility on the c.e. reals. We also show the s.c.e. monotone degrees contain an infinite antichain and a countable dense linear ordering. (shrink)

Calhoun, W.C., Incomparable prime ideals of recursively enumerable degrees, Annals of Pure and Applied Logic 63 39–56. We show that there is a countably infinite antichain of prime ideals of recursively enumerable degrees. This solves a generalized form of Post's problem.

The simple systems methodology is a powerful reductionistic research strategy. It has problems as implemented in developmental genetics because the organisms studied are few and unrepresentative. Stronger inferences require independent arguments that key traits are widely distributed phylogenetically. Evolutionary and developmental mechanisms of generative entrenchment and self-organization provide possible support, and are also necessary components of a developmental systems approach.

Various philosophers have used the image of a game as a metaphor to better interpret and deal with the world. In The Game of Philosophy, William C. Soderberg introduces the reader to the search for fairness in this game; a search that has been one of the main goals of moral and political philosophy. Soderberg examines the debate over the definition of a "fair social game" from various traditions and perspectives such as European, Anglo-American, African-American, multi-cultural, and feminist. The (...) debate between liberals and communitarians is a central theme of the moral and political philosophy section, and Soderberg explores the roots of this debate in the sections on metaphysics, epistemology, and philosophy of religion. In metaphysics and philosophy of religion, Soderberg presents both practical and speculative approaches; and he traces the emergence of anti-foundationalism in various epistemological traditions. A marvelous foundation text, this book will be of great value to beginning philosophers. (shrink)

We examine initial public offering (IPO) holdings in the mutual funds of four large investment banks and five large non-investment banks during the period 1997 through 2002. Investment banks hold IPOs with different characteristics than IPOs held by noninvestment banks, and they also tend to hold IPOs in different types of funds than non-investment banks. We classify holdings as to whether the IPO lies outside or inside the fund's objective. Investment banks hold IPOs outside the fund objective in 27% of (...) the fund/IPO pairs while non-investment banks hold outside their objective in just 5.4% of fund/IPO pairs. We see significant differences in IPO underpricing for both groups as well. For example, when non-investment banks hold IPOs outside a large capitalization fund objective, they select IPOs with 52% higher underpricing as measured by first-day returns. (shrink)

Pandeism claims that God became the Universe at a moment called the Becoming. For it to be possible, the Universe and God cannot be so irreconcilably different that the Becoming would require a miraculous transformation. In four ways especially they must be similar. First, since God is One the Universe must be One; it must be a unified reality. Second, God and the Universe cannot be irreconcilably different in substance as would be the case if God were spirit and the (...) Universe were matter (as those terms are usually understood). Third, the Universe must be conscious, and include as many distinct subjects and objects of consciousness as possible. Fourth, God-and-Universe together must be eternal. This paper argues that our Universe may meet all of these criteria. (shrink)

Business ethics in the new millennium will confront both new and old questions that are being transformed by the changed pace and direction of human evolution. These questions embrace human nature, values, inquiring methods, technological change, geopolitics, natural disasters, and the moral role of business in all of these. The emergence and acceptance of technosymbolic phenomena may signal a slow transition of carbon-based human life toward greater dependence upon silicon-based virtualities across a wide range ofhuman possibilities. The resultant moral issues (...) call for a renewal and redefinition of business ethics theories and methods. (shrink)
