This paper explores the complex relationship between the plant evolutionist G. Ledyard Stebbins and the animal evolutionist Theodosius Dobzhansky. The manner in which the plant evolution was brought into line, synthesized, or rendered consistent with the understanding of animal evolution (and especially insect evolution) is explored, especially as it culminated with the publication of Stebbins's 1950 book Variation and Evolution in Plants. The paper explores the multi-directional traffic of influence between Stebbins and Dobzhansky, but also their (...) social and professional networks that linked plant evolutionists like Stebbins with Edgar Anderson, Carl Epling, and the 'Carnegie team' of Jens Clausen, David Keck, and William Hiesey with collaborators on the animal side like I. Michael Lerner, Sewall Wright and L.C. Dunn and other 'architects' of the synthesis like Ernst Mayr, Julian Huxley and George Gaylord Simpson. The compatibility in training, work styles, methodologies, goals, field sites, levels of analysis, and even choice of organismic systems is explored between Stebbins and Dobzhansky. Finally, the extent to which coevolution between plants and insects is reflected in the relationship is explored, as is the power dynamic in the relationship between two of the most visible figures associated with the evolutionary synthesis.

This paper explores the special problems encountered by the biographer of a living scientific subject. In particular, it explores the complex of problems that emerges from the intense interpersonal dynamic involving issues of distance, privacy and trust. It also explores methodological problems having to do with oral history interviews and other supporting documentation. It draws on the personal experience of the author and the biographical subject of G. Ledyard Stebbins Jr., the botanist, geneticist and evolutionist. It also offers (...) prescriptives and recommendations for future research. (shrink)

Tracing the contributions of Edgar Anderson (1897-1969) of the Missouri Botanical Garden to the important discussions in evolutionary biology in the 1940s, this paper argues that Anderson turned to corn research rather than play a more prominent role in what is now known as the Evolutionary Synthesis. His biosystematic studies of Iris and Tradescantia in the 1930s reflected such Synthesis concerns as the species question and population thinking. He shared the 1941 Jesup Lectures with Ernst Mayr. But rather than preparing (...) his lectures as a potentially key text in the Synthesis, Anderson began researching Zea mays -- its taxonomy, its origin, and its agronomic role. In this study, Anderson drew on the disciplines of taxonomy, morphology, genetics, geography, anthropology, archaeology, and agronomy among others in his own creative synthesis. Though his maize research in the 1940s represented the most sustained work of his career, Anderson was also drawn in many directions during his professional life. For example, he enjoyed teaching, working with amateurs, and popular writing. (shrink)

"One of the most careful and intensive among the introductory texts that can be used with a wide range of students. It builds remarkably sophisticated technical skills, a good sense of the nature of a formal system, and a solid and extensive background for more advanced work in logic.... The emphasis throughout is on natural deduction derivations, and the text's deductive systems are its greatest strength. Lemmon's unusual procedure of presenting derivations before truth tables is very effective." --Sarah Stebbins, (...) The Journal of Symbolic Logic. (shrink)

Bazzocchi disposes the text of the Tractatus in a user-friendly manner, exactly as Wittgenstein's decimals advise. This discloses the logical form of the book by distinct reading units, linked into a fashioned hierarchical tree. The text becomes much clearer and every reader can enjoy, finally, its formal and literary qualities.

Organisms that share the capability of storing information about experiences in the past have an actively generated background resource on which they can compare and evaluate more recent experiences in order to quickly or even better react than in previous situations. This is an essential competence for all reaction and adaptation purposes of living organisms. Such memory/learning skills can be found from akaryotes up to unicellular eukaryotes, fungi, animals and plants, although until recently, it had been mentioned only as a (...) capability of higher animals. With the rise of epigenetics, the context-dependent marking of experiences at both the phenotype and the genotype level is an essential perspective to understand memory and learning in all organisms. Both memory and learning depend on a variety of successful communication processes within the whole organism. (shrink)

Keine ausführliche Beschreibung für "Über das Wesen der Naturgesetze" verfügbar.

This book is written by a philosopher for other philosophers and for that section of the reading public who buy in large quantities and, no doubt, devour with great earnestness the popular books written by scientists for their enlightenment. We common readers, to adapt a phrase from Samuel Johnson, are fitted neither to criticize physical theories not to decide what precisely are their implications. We are dependent upon the scientists for an exposition of those developments which - so we find (...) them proclaiming - have important and far-reaching consequences for philosophy. Unfortunately, however, our popular expositors do not always serve us very well. The two who are most widely read in this country are Sir Arthur Eddington and Sir James Jeans. They are not always reliable guides. Their influence has been considerable upon the reading public, upon theologians, and upon preachers; they have even misled philosopher who should have known better. Accordingly, it has seemed to me to be worth while to examine in some detail the philosophical views that they have put forth and to criticize the grounds upon which these views are based. (shrink)

This is the first complete, one-volume English translation of the ancient Chinese text Xunzi, one of the most extensive, sophisticated, and elegant works in the tradition of Confucian thought. Through essays, poetry, dialogues, and anecdotes, the Xunzi articulates a Confucian perspective on ethics, politics, warfare, language, psychology, human nature, ritual, and music, among other topics. Aimed at general readers and students of Chinese thought, Eric Hutton’s translation makes the full text of this important work more accessible in English than ever (...) before. Named for its purported author, the Xunzi has long been neglected compared to works such as the Analects of Confucius and the Mencius. Yet interest in the Xunzi has grown in recent decades, and the text presents a much more systematic vision of the Confucian ideal than the fragmented sayings of Confucius and Mencius. In one famous, explicit contrast to them, the Xunzi argues that human nature is bad. However, it also allows that people can become good through rituals and institutions established by earlier sages. Indeed, the main purpose of the Xunzi is to urge people to become as good as possible, both for their own sakes and for the sake of peace and order in the world. In this edition, key terms are consistently translated to aid understanding and line numbers are provided for easy reference. Other features include a concise introduction, a timeline of early Chinese history, a list of important names and terms, cross-references, brief explanatory notes, a bibliography, and an index.

What does it mean to be an individual and how can an individual exist within society? Serious Leisure and Individuality examines the circumstances in the modern world that make for individual distinctiveness, and the role of these conditions in personal and social life. "The individual," said Friedrich Nietzsche, "has always had to struggle to keep from being overwhelmed by the tribe. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay (...) for the privilege of owning yourself." Elie Cohen-Gewerc and Robert Stebbins explore the road to finding that privilege. They approach individuality by examining its relationship to freedom and being free, and by defining and elaborating on the concept of leisure space. They also look at individuality's place in community, citizenship, and globalization. The complex relationship between individuality and alienation is put under the microscope to highlight the negative side of being distinctive, which has adverse consequences for the individual and society. There are many studies on the modern individual that centre almost entirely on the person facing his local community and broader society. What is missing in the literature - and what Serious Leisure and Individuality provides - is a broad, comprehensive examination of individuality, particularly as it is rooted in leisure and the leisure-like areas of work.

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

Excerpt from Zur Psychologie des Asthetischen Genusses Die erste Erfahrung, auf der uberhaupt die Existenz berechtigung einer Wissenschaft wie der Asthetik beruht, ist die, da durch Einwirkung gewisser Objekte auf unsere Sinne ein Wohlgefallen in uns erzeugt wird, das wir unmittelbar und mit ziemlicher Sicherheit von allen anderen Arten des Wohlgefallens unterscheiden. Wenn wir versuchen, diesen zunachst nur gefiihlten Unterschied zu begrifi'licher Klarheit emporzuheben, so bemerken wir, da das asthetische Wohl gefallen durch zwei Eigenschaften charakterisiert und von allen anderen Arten (...) des Glucksgefiihls geschieden ist: erstens knupft es sich nicht an Elementarvorstellungen also ein fache Empfindungen sondern an Vorstellungskomplexe, und zweitens setzt es nicht die reale oder gedachte Erfullung einer zielsetzenden Tatigkeit voraus, sondern hat sein Ziel allein in sich selbst. Durch die erste Bestimmung unterscheidet es sich von sinnlichen Lustgefuhlen, durch die zweite von allen anderen Arten des Wohlgefallens, die wir aus leicht ersieht lichen Grunden als praktisch bezeichnen wollen.

We characterize a type of functional explanation that addresses why a homologous trait originating deep in the evolutionary history of a group remains widespread and largely unchanged across the group’s lineages. We argue that biologists regularly provide this type of explanation when they attribute conserved functions to phenotypic and genetic traits. The concept of conserved function applies broadly to many biological domains, and we illustrate its importance using examples of molecular sequence alignments at the intersection of evolution and cell biology. (...) We use these examples to show how the study of conserved functions can integrate knowledge of a trait’s causal effects on fitness and its history of natural selection without invoking adaptation. We also show how conserved function provides a novel basis for addressing objections against evolutionary functions raised by Robert Cummins. (shrink)

To have a vocation is to be called to a life of ongoing participation in the redemptive work of the Son and the Holy Spirit. Being faithful to the vocation we have received requires adopting a stance of continuing alertness, ready to notice, correctly interpret, and effectively respond to the various forms of communication by which God draws us into closer cooperation with the redemptive missions of the Son and the Spirit. In this paper I focus on a particular vehicle (...) by which the divine call is transmitted to us—namely, the God-given desire to know, which we experience whenever we wonder about something, whenever we try to solve a problem, whenever we learn or explore or plan.
