I defend the historical definition of "function" originally given in my Language, Thought and Other Biological Categories (1984a). The definition was not offered in the spirit of conceptual analysis but is more akin to a theoretical definition of "function". A major theme is that nonhistorical analyses of "function" fail to deal adequately with items that are not capable of performing their functions.

Biological functions are dispositions or effects a trait has which explain the recent maintenance of the trait under natural selection. This is the "modern history" approach to functions. The approach is historical because to ascribe a function is to make a claim about the past, but the relevant past is the recent past; modern history rather than ancient.

Friedrich Nietzsche has emerged as one of the most important and influential modern philosophers. For several decades, the book series Monographien und Texte zur Nietzsche-Forschung (MTNF) has set the agenda in a rapidly growing and changing field of Nietzsche scholarship. The scope of the series is interdisciplinary and international in orientation reflects the entire spectrum of research on Nietzsche, from philosophy to literary studies and political theory. The series publishes monographs and edited volumes that undergo a strict peer-review process. The (...) book series is led by an international team of editors, whose work represents the full range of current Nietzsche scholarship. (shrink)

Ernst Mayr has argued that Darwinian theory discredited essentialist modes of thought and replaced them with what he has called "population thinking". In this paper, I characterize essentialism as embodying a certain conception of how variation in nature is to be explained, and show how this conception was undermined by evolutionary theory. The Darwinian doctrine of evolutionary gradualism makes it impossible to say exactly where one species ends and another begins; such line-drawing problems are often taken to be the decisive (...) reason for thinking that essentialism is untenable. However, according to the view of essentialism I suggest, this familiar objection is not fatal to essentialism. It is rather the essentialist's use of what I call the natural state model for explaining variation which clashes with evolutionary theory. This model implemented the essentialist's requirement that properties of populations be defined in terms of properties of member organisms. Requiring such constituent definitions is reductionistic in spirit; additionally, evolutionary theory shows that such definitions are not available, and, moreover, that they are not needed to legitimize population-level concepts. Population thinking involves the thesis that population concepts may be legitimized by showing their connections with each other, even when they are not reducible to concepts applying at lower levels of organization. In the paper, I develop these points by describing Aristotle's ideas on the origins of biological variation; they are a classic formulation of the natural state model. I also describe how the development of statistical ideas in the 19th century involved an abandoning of the natural state model. (shrink)

Nietzsche attributes 'will power' to all living things, but this seems in sharp conflict with other positions important to him-and implausible besides. The doctrine smacks of both metaphysics and anthropomorphizing, which he elsewhere derides. Will to power seems to be an intentional end-directedness, involving cognitive or representational powers he is rightly loath to attribute to all organisms, and tends to downplay even in persons. This paper argues that we find a stronger reading of will to power-both more plausible and more (...) consistent with Nietzsche's other views-by developing his affinities with Darwinism. By seeing will to power as an 'internal revision' to Darwinism, opposing the latter's stress (as Nietzsche thinks) on 'survival', but assenting to its uses of natural selection, we can ground or naturalize that notion, congenially to Nietzsche and to us.

Morrison offers an illuminating study of two linked traditions that have figured prominently in twentieth-century thought: Buddhism and the philosophy of Nietzsche. Nietzsche admired Buddhism, but saw it as a dangerously nihilistic religion; he forged his own affirmative philosophy in reaction against the nihilism that he feared would overwhelm Europe. Morrison shows that Nietzsche's influential view of Buddhism was mistaken, and that far from being nihilistic, it has notable and perhaps surprising affinities with Nietzsche's own project of the transvaluation of (...) all values.

The concept of "fitness" is a notion of central importance to evolutionary theory. Yet the interpretation of this concept and its role in explanations of evolutionary phenomena have remained obscure. We provide a propensity interpretation of fitness, which we argue captures the intended reference of this term as it is used by evolutionary theorists. Using the propensity interpretation of fitness, we provide a Hempelian reconstruction of explanations of evolutionary phenomena, and we show why charges of circularity which have been levelled (...) against explanations in evolutionary theory are mistaken. Finally, we provide a definition of natural selection which follows from the propensity interpretation of fitness, and which handles all the types of selection discussed by biologists, thus improving on extant definitions.

Biological species have been treated traditionally as spatiotemporally unrestricted classes. If they are to perform the function which they do in the evolutionary process, they must be spatiotemporally localized individuals, historical entities. Reinterpreting biological species as historical entities solves several important anomalies in biology, in philosophy of biology, and within philosophy itself. It also has important implications for any attempt to present an "evolutionary" analysis of science and for sciences such as anthropology which are devoted to the study of single (...) species.

" The essays also consider specific works by Nietzsche, including Human, All Too Humanand The Genealogy of Morals, as well as the philosopher's artistic metaphysics and semantical nihilism.

This paper gives an account of evolutionary explanations in biology. Briefly, the explanations I am primarily concerned with are explanations of adaptations. These explanations are contrasted with other nonteleological evolutionary explanations. The distinction is made by distinguishing the different kinds of questions these different explanations serve to answer. The sense in which explanations of adaptations are teleological is spelled out.

The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

In the early nineteenth century, a group of German biologists led by Johann Friedrich Blumenbach and Karl Friedrich Kielmeyer initiated a search for laws of biological organization that would explain the phenomena of form and function and establish foundations for a unified theory of life. The tradition spawned by these efforts found its most important spokesman in Karl Ernst von Baer. Timothy Lenoir chronicles the hitherto unexplored achievements of the practitioners of this research tradition as they aimed to place functional (...) morphology at the heart of a new science, which they called "biology." Strongly influenced by Immanuel Kant, the biologists’ approach combined a sophisticated teleology with mechanistic theories and sparked bitter controversies with the rival programs, mechanistic reductionism and Darwinism. Although temporarily eclipsed by these two approaches, the morphological tradition, Lenoir argues, was not vanquished in the field of scientific debate. It contributed to pathbreaking research in areas such as comparative anatomy, embryology, paleontology, and biogeography. Preface Introduction 1. Vital Materialism 2.

Poellner here offers a comprehensive interpretation of Nietzsche's later ideas on epistemology and metaphysics, drawing extensively not only on his published works but also his voluminous notebooks, largely unpublished in English. He examines Nietzsche's various distinct lines of thought on the traditionally central areas of philosophy and shows in what specific sense Nietzsche, as he himself claimed, might be said to have moved beyond these questions. He pays considerable attention throughout both to the historical context of Nietzsche's writings and to (...) subsequent developments in philosophy--English-language as well as Continental. (shrink)

This is the first translation into English of a milestone in Nietzsche interpretation. Wolfgang Mller-Lauter examines Nietzsche's doctrines of the will to power and the overman in light of Nietzsche's philosophy of real contradictions.

This book argues, against recent interpretations, that Nietzsche does in fact have a metaphysical system--but that this is to his credit. Rather than renouncing philosophy's traditional project, he still aspires to find and state essential truths, both descriptive and valuative, about us and the world. These basic thoughts organize and inform everything he writes; by examining them closely we can find the larger structure and unifying sense of his strikingly diverse views. With rigor and conceptual specificity, Richardson examines the will-to-power (...) ontology and maps the values that emerge from it. He also considers the significance of Nietzsche's famous break with Plato--replacing the concept of "being" with that of "becoming." By its conservative method, this book tries to do better justice to the truly radical force of Nietzsche's ideas--to demonstrate more exactly their novelty and interest. (shrink)

Friedrich Nietzsche haunts the modern world. His elusive writings with their characteristic combination of trenchant analysis of the modern predicament and suggestive but ambiguous proposals for dealing with it have fascinated generations of artists, scholars, critics, philosophers, and ordinary readers. Maudemarie Clark's highly original study gives a lucid and penetrating analytical account of all the central topics of Nietzsche's epistemology and metaphysics, including his views on truth and language, his perspectivism, and his doctrines of the will-to-power and the eternal recurrence. (...) The Nietzsche who emerges from these pages is a subtle and sophisticated philosopher, whose highly articulated views are of continuing interest as contributions to a whole range of philosphical issues. This remarkable reading of Nietzsche will interest not only philosophers, but also readers in neighbouring disciplines such as literature and intellectual history. (shrink)

Nietzsche's vision of the 'overman' continues to haunt the postmodern imagination. His call that 'man is something that must be overcome' can no longer be seen as simple rhetoric. Our experiences of the hybrid realities of artificial life have made the 'transhuman' a figure that looks over us all. Inspired by this vision, Keith Ansell Pearson sets out to examine if evolution is 'out of control' and machines are taking over. In a series of six fascinating perspectives, he links Nietzsche's (...) thought with the issues at stake in contemporary conceptions of evolution from the biological to the technological. _Viroid Life; Perspectives on Nietzsche and the Transhuman Condition_ considers the hybrid, 'inhuman' character of our future with the aid of Nietzsche's philosophy. Keith Ansell Pearson contrasts Nietzsche and Darwin before introducing the more recent figures such as Giles Deleuze and Guy Debord to sketch a new thinking of technics and machines and stress the ambiguous character of our 'machine enslavement'.
