During the first forty years of this century, the concept of a living organism was discussed widely and publicly by biologists and philosophers. Two questions in particular excited discussion. In what ways should organisms be considered different from or the same as dead matter? And what can we learn about the nature of human society by regarding it as analogous to a living organism? Inevitably, these questions were closely related; the conclusions to be drawn about the social organism would depend (...) upon the particular properties attributed to the biological organism. In more recent years, discussion of these issues has largely been in abeyance, as biologists have with-drawn from debate over social policy into a more remote academia. A few biologists who still see their work as relevant to a wider social agenda have continued to treat the nature of life as a contentious issue. But the focus of interest has shifted away from the organismic analogy, which concerns the organization of society as a whole, to issues like sociobiology and evolutionary theory, which emphasize social differentiation and the treatment of out-groups and minorities.

ABSTRACT. This paper contemplates Organicism and its relation with molecular and evolutionary biology. We explore whether twentieth-first century biology is returning to positions held at the beginning of the twentieth century and then abandoned. The guiding line is a history of theoretical biology in which we distinguish three periods: 1. The 20s-30s, and the Theoretical Biology Club (Needham, Woodger, and Waddington, among others); 2. An intermediate period in the 60s-70s, in which, in spite of the eclosion of the molecular and (...) evolutionary biologies, there is some recovery of organicist positions, and 3. The present post-genomic situation, which is demanding a systemic approach. (shrink)

The writings of Joseph Henry Woodger (1894–1981) are often taken to exemplify everything that was wrongheaded, misguided, and just plain wrong with early twentieth-century philosophy of biology. Over the years, commentators have said of Woodger: (a) that he was a fervent logical empiricist who tried to impose the explanatory gold standards of physics onto biology, (b) that his philosophical work was completely disconnected from biological science, (c) that he possessed no scientific or philosophical credentials, and (d) that his work was (...) disparaged – if not altogether ignored – by the biologists and philosophers of his era. In this paper, we provide the first systematic examination of Woodger’s oeuvre, and use it to demonstrate that the four preceding claims are false. We argue that Woodger’s ideas have exerted an important influence on biology and philosophy, and submit that the current consensus on his legacy stems from a highly selective reading of his works. By rehabilitating Woodger, we hope to show that there is no good reason to continue to disregard the numerous contributions to the philosophy of biology produced in the decades prior to the professionalization of the discipline.

In Unifying Biology, Smocovitis offers a series of claimsregarding the relationship between key actors in the synthesisperiod of evolutionary studies and positivism, especially claimsentailing Joseph Henry Woodger and the Unity of Science Movement.This commentary examines Woodger''s possible relevance to key synthesis actors and challenges Smocovitis'' arguments for theexplanatory relevance of logical positivism, and positivism moregenerally, to synthesis history. Under scrutiny, these arguments areshort on evidence and subject to substantial conceptual confusion.Though plausible, Smocovitis'' minimal interpretation – that somegeneralised form of Comtean (...) positivism had a role in synthesishistory – requires more of an evidential basis and must engageexisting scholarship on epistemic reforms in the biological sciencesprior to the synthesis period. Smocovitis is right to investigateepistemology in the synthesis period of evolutionary studies and tolook for links to wider changes in science and philosophy. However,in its present form, Unifying Biology fails to support herbasic interpretation. (shrink)

Philosophy of biology is often said to have emerged in the last third of the twentieth century. Prior to this time, it has been alleged that the only authors who engaged philosophically with the life sciences were either logical empiricists who sought to impose the explanatory ideals of the physical sciences onto biology, or vitalists who invoked mystical agencies in an attempt to ward off the threat of physicochemical reduction. These schools paid little attention to actual biological science, and as (...) a result philosophy of biology languished in a state of futility for much of the twentieth century. The situation, we are told, only began to change in the late 1960s and early 1970s, when a new generation of researchers began to focus on problems internal to biology, leading to the consolidation of the discipline. In this paper we challenge this widely accepted narrative of the history of philosophy of biology. We do so by arguing that the most important tradition within early twentieth-century philosophy of biology was neither logical empiricism nor vitalism, but the organicist movement that flourished between the First and Second World Wars. We show that the organicist corpus is thematically and methodologically continuous with the contemporary literature in order to discredit the view that early work in the philosophy of biology was unproductive, and we emphasize the desirability of integrating the historical and contemporary conversations into a single, unified discourse.

T. H. Morgan, A. H. Sturtevant, H. J. Muller and C. B. Bridges published their comprehensive treatise "The Mechanism of Mendelian Heredity" in 1915. By 1920 Morgan 's "Chromosome Theory of Heredity" was generally accepted by geneticists in the United States, and by British geneticists by 1925. By 1930 it had been incorporated into most general biology, botany, and zoology textbooks as established knowledge. In this paper, I examine the reasons why it was accepted as part of a series of (...) comparative studies of theory-acceptance in the sciences. In this context it is of interest to look at the persuasiveness of confirmed novel predictions, a factor often regarded by philosophers of science as the most important way to justify a theory. Here it turns out to play a role in the decision of some geneticists to accept the theory, but is generally less important than the CTH's ability to explain Mendelian inheritance, sex-linked inheritance, non-disjunction, and the connection between linkage groups and the number of chromosome pairs; in other words, to establish a firm connection between genetics and cytology. It is remarkable that geneticists were willing to accept the CTH as applicable to all organisms at a time when it had been confirmed only for Drosophila. The construction of maps showing the location on the chromosomes of genes for specific characters was especially convincing for non-geneticists. (shrink)

An interdisciplinary fusion between the philosophy of science and the teaching of science can help to eradicate the disciplinary rigidity entrenched in both. In this paper I approach the history of sciencethematically, identifying general themes which transcend the boundaries of individual disciplines. Such conceptual themes can be used as a basis for an interdisciplinary introduction to university science, encouraging certain important cognitive skills not exercised during the disciplinary training emphasised in traditional approaches. Courses which teach themes such as conservation, randomness, (...) and holism/reductionism have already proved successful, and these innovations should encourage philosophers and historians to explore the exciting new possibilities which arise from stepping outside the confines of a single discipline.

This article looks at how fisheries biologists of the early twentieth century conceptualized and measured overfishing and attempted to make it a scientific object. Considering both theorizing and physical practices, the essay shows that categories and understandings of both the fishing industry and fisheries science were deeply and, at times, inextricably interwoven. Fish were both scientific and economic objects. The various models fisheries science used to understand the world reflected amalgamations of biological, physical, economic, and political factors. As a result, (...) scientists had great difficulty stabilizing the concept of overfishing and many influential scholars into the 1930s even doubted the coherence of the concept. In light of recent literature in history of fisheries and environmental social sciences that critiques the infiltration of political and economic imperatives into fisheries and environmental sciences more generally, this essay highlights both how early fisheries scientists understood their field of study as the entire combination of interactions between political, economic, biological and physical factors and the work that was necessary to separate them.

This article is a systematic critical survey of work done in the philosophy of biology within the logical empiricist tradition, beginning in the 1930s and until the end of the 1950s. It challenges a popular view that the logical empiricists either ignored biology altogether or produced analyses of little value. The earliest work on the philosophy of biology within the logical empiricist corpus was that of Philipp Frank, Ludwig von Bertalanffy, and Felix Mainx. Mainx, in particular, provided a detailed analysis (...) of biology in the 1930s and 1940s in his contribution to the logical empiricists’ Encyclopedia of Unified Science. However, the most important contributions to the philosophy of biology were those of Joseph Henry Woodger and Ernest Nagel. Woodger is primarily remembered for deploying the axiomatic method in biology but he also used semiformal methods for the analysis of many biological problems. While Woodger’s axiomatic work was often derided by some later philosophers of biology (e.g., David Hull and Michael Ruse), this article defends both the biological and the philosophical significance of some of that work, for instance, those aspects that led to the recognition of the conceptual complexity of mereology and temporal identity in biological systems. Woodger’s semiformal analyses were even more important, for instance, his explication of the concepts of the Bauplan and of innateness. Nagel’s importance lies in his analyses of reduction and emergence in the context of all empirical sciences and his use of these analyses in a careful exploration of biological problems. While Nagel’s model of reduction was generally rejected by philosophers of science in the 1970s and 1980s, particularly for biological contexts, it has recently been sympathetically reconstructed by many commentators; this article defends its continued relevance for the philosophy of biology.

ArgumentD’Arcy Thompson has often been portrayed as a loner. His science of form has frequently been labeled anachronistic, idiosyncratic, and unconnected to his contemporary biology. This article aims to challenge this interpretation. Thompson's representation as a loner did not lie in the idiosyncrasies of his science, but in our own historiography. Through the use of unedited archival sources, this study shows that Thompson's biology was well-connected to an international research program – a program mainly shared by developmental biologists, physiologists, and (...) morphologists. In addition, this article also aims to propose a new interpretation of Thompson'sOn Growth and Form. Drawing on his private correspondence and published sources, the paper re-contextualizes the contents and conclusions of Thompson's seminal work. We will see that Thompson defended a particular kind of organismal biology. The bio-science he supported stemmed not only from Aristotle's zoology or Pythagorean mathematics, but had many allies among twentieth-century naturalists. (shrink)

According to vitalism, living organisms differ from machines and all other inanimate objects by being endowed with an indwelling immaterial directive agency, ‘vital force,’ or entelechy . While support for vitalism fell away in the late nineteenth century many biologists in the early twentieth century embraced a non vitalist philosophy variously termed organicism/holism/emergentism which aimed at replacing the actions of an immaterial spirit with what was seen as an equivalent but perfectly natural agency—the emergent autonomous activity of the whole organism. (...) Organicists hold that organisms unlike machines are ‘more than the sum of their parts’ and predict that the vital properties of living things can never be explained in terms of mechanical analogies and that the reductionist agenda is doomed to failure. Here we review the current status of the mechanist and organicist conceptions of life particularly as they apply to the cell. We argue that despite the advances in biological knowledge over the past six decades since the molecular biological revolution, especially in the fields of genetics and cell biology the unique properties of living cells have still not been simulated in mechanical systems nor yielded to reductionist—analytical explanations. And we conclude that despite the dominance of the mechanistic–reductionist paradigm through most of the past century the possibility of a twentyfirst century organicist revival cannot be easily discounted.
