This is an epistemologically-driven history of the concept of evolution. Starting from its inception, this work will follow the development of this pregnant concept. However, in contradistinction to previous attempts, the objective will not be the identification of the different meanings it adopted through history, but conversely, it will let the concept to be unfolded, to be explicated and to express its own inner potentialities. The underlying thesis of the present work is, therefore, that the path that leads to the (...) development of the concept of evolution is the path that studies the possibilities of the evolution of concepts, and that the historical reconstruction of its conceptual trajectory will shed light into potential and unexploited possibilities. This methodology will provide useful tools and resources for future developments of the concept. For example, it will define the concept of transmutation as a different conceptual trajectory deviating from the one corresponding to evolution, at the onset of the 19th century. Moreover, epigenesis will not be the opposing concept to evolution, but only to simultaneous and instantaneous generation. It will demonstrate that every important system of epigenesis drew upon some kind of formative power to explain development. More importantly, it will show that the problem of preformation cannot be overlooked, and that some kind of virtual preformation must be considered in order to address the problems of generation and development.

Historians tend to speak of the problem of the origin of species or the species question, as if it were a monolithic problem. In reality, the phrase refers to a, historically, surprisingly fluid and pluriform scientific issue. It has, in the course of the past five centuries, been used in no less than ten different ways or contexts. A clear taxonomy of these separate problems is useful or relevant in two ways. It certainly helps to disentangle confusions that have inevitably (...) emerged in the literature in its absence. It may, secondly, also help us to gain a more thorough understanding, or sharper view, of the history of evolutionary thought. A consequent problem-centric look at that history through the lens of various origin of species problems certainly yields intriguing results, including and particularly for our understanding of the genesis of the Wallace–Darwin theory of evolution through natural selection.

Herbert Spencer was one of the most important contributors to the Victorian discourse on social evolution. His theory of evolution in nature and society has been the subject of countless scholarly works over the last hundred years. Nevertheless, not all of its dimensions have been studied in due depth. Contrary to a widespread belief, Spencer did not just design an evolutionary theory of upward, yet branched development. Searching for explanations for the social distance between presumably civilized and primitive societies and (...) between presumably well-conducted and pauperized Victorians, he introduced elements of retrogression into his theory of social evolution. In addition, he biologized social structures and social phenomena by constructing a causal relationship between social and somatic features. This article discusses Spencer's account of the social conditions of the so-called savages and paupers. It aims to shed light on the progressive and retrogressive modes of evolutionary development and the biologistic explanations he employed in his social theory to explain these conditions. (shrink)

Recently, the nature of science (NOS) has become recognized as an important element within the K-12 science curriculum. Despite differences in the ultimate lists of recommended aspects, a consensus is emerging on what specific NOS elements should be the focus of science instruction and inform textbook writers and curriculum developers. In this article, we suggest a contextualized, explicit approach addressing one core NOS aspect: the human aspects of science that include the domains of creativity, social influences and subjectivity. To illustrate (...) these ideas, we have focused on Charles Darwin, a scientist whose life, work and thought processes were particularly well recorded at the time and analyzed by scholars in the succeeding years. Historical facts are discussed and linked to core NOS ideas. Creativity is illustrated through the analogies between the struggle for existence in human societies and in nature, between artificial and natural selection, and between the division of labor in human societies and in nature. Social influences are represented by Darwin’s aversion of criticism of various kinds and by his response to the methodological requirements of the science of that time. Finally, subjectivity is discussed through Darwin’s development of a unique but incorrect source for the origin of variations within species. (shrink)

Two of the most influential works of the Western nineteenth century were completed in 1859: Charles Darwin’s The Origin of Species and Richard Wagner’s opera Tristan and Isolde. Although created within very different cultural traditions, these works show some striking similarities: both brought about a critical, long-lasting debate and caused conflicting reactions after their publications, and both had fundamental and compelling impact on their disciplines. The perspective discussed in this paper, however, is that both works address the notion of evolutionary (...) thought. In 2009 we could have thus celebrated a double anniversary: it was 150 years since the manifestation of the evolutionary idea in such different .. (shrink)

The nineteenth century saw the rise of Darwinism as a new paradigm for the study of nature and man mans an integral part thereof. Many scholars were intent on removing the abstract principles and universal truths of early modern philosophy in favour of understanding man's nature through more scientifically-based methods. Walter Bagehot (1826?1877) was one of the leading exponents of this view. Our focus is on one of Bagehot's famous books, Physics and Politics, or thoughts on the application of the (...) principles of `natural selection' and `inheritance' to political society. Physics and Politics can be seen as one of the most remarkable attempts to think the intertwining of politics and Darwinism. In our paper, we want to examine Bagehot's efforts to apply natural sciences to politics and philosophy and his focus on progress and the idea that such progress is inherited over generations. We want to examine in what way a Darwinian framework of thinking is actually used in Physics and Politics. Our conclusion is that perhaps Physics and Politics established a framework for the application of biological principles to political society, but it definitely did not do so for the application of Darwin's principle of natural selection.

Variational evolutionary theory as advocated by Darwin is not a single theory, but a bundle of related but independent theories, namely: (a) variational evolution; (b) gradualism rather than large leaps; (c) processes of phyletic evolution and of speciation; (d) causes for the formation of varying individuals in populations and for the action of selective agents; and (e) all organisms evolved from a common ancestor. The first four are nomological-deductive explanations and the fifth is historical-narrative. Therefore evolutionary theory must be divided (...) into nomological and historical theories which are both testable against objective empirical observations. To be scientific, historical evolutionary theories must be based on well corroborated nomological theories, both evolutionary and functional. Nomological and general historical evolutionary theories are well tested and must be considered as strongly corroborated scientific theories. Opponents of evolutionary theory are concerned only with historical evolutionary theories, having little interest in nomological theory. Yet given a well corroborated nomological evolutionary theory, historical evolutionary theories follow automatically. If understood correctly, both forms of evolutionary theories stand on their own as corroborated scientific theories and should not be labeled as facts. (shrink)

The aim of this paper is to explain why, while Charles Darwin was well recognized as a scientific leader of his time, Claude Bernard never really regarded Darwinism as a scientific theory. The lukewarm reception of Darwin at the Académie des Sciences of Paris and his nomination to a chair only after 8 years contrasts with his prominence, and Bernard’s attitude towards Darwin’s theory of species evolution belongs to this French context. Yet we argue that Bernard rejects the scientific value (...) of Darwinian principles mainly for epistemological reasons. Like Darwin, Bernard was interested in hereditary processes, and planned to conduct experiments on these processes that could lead to species transformation. But the potential creation of new forms of life would not vindicate Darwinism since biologists can only explain the origin of morphotypes and morphological laws by the means of untestable analogies. Because it can be the object neither of experiments nor of any empirical observation, phylogeny remains out of science’s scope. Around 1878 Bernard foresaw a new general physiology based on the study of protoplasm, which he saw as the agent of all basic living phenomena. We will analyze why Bernard regarded Darwinism as part of metaphysics, yet still referred to Darwinians in his latter works in 1878. Basically, the absence of a scientific reception of Darwinism in Bernard's work should not obscure its philosophical reception, which highlights the main principles of Bernard’s epistemology.

The traditional practice of establishing morphological types and investigating morphological organization has found new support from evolutionary developmental biology (evo-devo), especially with respect to the notion of body plans. Despite recurring claims that typology is at odds with evolutionary thinking, evo-devo offers mechanistic explanations of the evolutionary origin, transformation, and evolvability of morphological organization. In parallel, philosophers have developed non-essentialist conceptions of natural kinds that permit kinds to exhibit variation and undergo change. This not only facilitates a construal of species (...) and higher taxa as natural kinds, but also broadens our perspective on the diversity of kinds found in biology. There are many different natural kinds relevant to the investigative and explanatory aims of evo-devo, including homologues and developmental modules. (shrink)

In his classic study,The Great Chain of Being, Arthur Lovejoy delineated a complex set of concepts and assumptions which referred to the perfection of God and the fullness of creation. In attempting to distil the basic or ‘unit idea’ which constituted this pattern of thought, he focused on the assumption that ‘the universe is aplenum formarumin which the range of conceivable diversity ofkindsof living things is exhaustively exemplified’. He called this the ‘principle of plenitude’. Lovejoy argued that this idea implied (...) two others—continuity and gradation—and that together these reflected a pre-occupation with the ‘necessity of imperfection in all its possible degrees’, a concern which had pervaded Western thought since Plato and gave rise to the powerful ontology known as the ‘great chain of being’.

On the occasion of its recent centennial, we trace the remarkable history of Herbert Spencer's 2,240 page Principles of Sociology , the most inductive, systematic, and comprehensive study of human society ever attempted. Spencer's bold aim was to establish empirically and then to explain (after the manner of the natural sciences) the 'relations of co-existence and sequence' among social phenomena. The database ('mass of evidence') required was so vast that it was published as a separate work, some eight folio volumes (...) called Descriptive Sociology . A major force in the making of both scientific sociology and anthropology in the last quarter of the nineteenth century, Spencer's magnum opus was all but lost to these fields by the early decades of the twentieth century. The present generation, however, is witnessing a growing revival of interest in Spencer's thought. For many, his confident vision of a natural science of society still offers the best hope for understanding human societies and how they have come to be as they are. (shrink)

_ Source: _Volume 9, Issue 2, pp 196 - 219 In his 1978 On Human Nature, Edward Wilson defined the evolutionary epic as the scientific story of all life, a linear narrative beginning with the big bang and ending with the story of human history. Since that time several popular science writers have attempted to write that story of life producing such titles as The Universe Story and The Epic of Evolution. Historians have also gotten into the act under the (...) guise of “Big History,” which has resulted in a series of monographs and is taught at several universities and high schools throughout the world. While the evolutionary epic is often presented as a novel way of bringing the historical insights of modern science into a narrative form that transcends the humanities–natural science divide, the genre itself originates in the nineteenth century, just as new geological and cosmic timescales were being established and new sciences such as biology and anthropology were being formalized. Several German Naturphilosophen and Victorian naturalists imagined the history of life as one, as a “Cosmos,” and produced evolutionary epics that bare significant similarities with their more modern counterparts. By considering the various recurrences of the evolutionary epic, from its origins in early German Romanticism and Victorian naturalism to the degeneration narratives of the fin de siècle and on to the Wilsonian and Big History versions of the late twentieth century and beyond, this essay seeks to map out a shared intellectual genealogy while examining the genre’s conceptual commonalities. What is perhaps most compelling about the history of the genre is the striking persistence of non-Darwinian forms of evolution that are utilized to situate the emergence of humanity in these epic narratives of life.

Species are generally considered to be the basic units of evolution, and hence to constitute spatio-temporally bounded entities. In addition, it has been argued that species also instantiate a natural kind. Evolution is fundamentally about change. The question then is how species can remain the same through evolutionary change. Proponents of the species qua individuals thesis individuate species through their unique evolutionary origin. Individuals, or spatio-temporally located particulars in general, can be bodies, objects, events, or processes, or a combination of (...) these. It is here argued that species are best understood as open or closed, causally integrated processual systems that also instantiate an historically conditioned homeostatic property cluster natural kind.

: The study of perfection, progress and evolution is a central theme in the history of ideas. This thesis explores this theme seen and understood as part of a discourse in the new fields of anthropology, sociology and psychology in the nineteenth century. A particular focus is on the stance taken by philosophers, scientists and writers in the discussion of theories of human physical and mental evolution, as well as on their views concerning the nature of social progress and historical (...) change. The wisdom and feasibility of improving the human species is discussed alongside an analysis of new methods of investigating and measuring physical and mental attributes of the human organism.The instruments used to assess the development of mind, body and society are described, and are viewed as part of an increased emphasis on the use of technology as an integral part of modern life, and as a means toward the ordered gathering of information in social-scientific practice. An international perspective is taken by observing the way in which ideas about the physical and mental development of humankind was discussed in light and consequence of English and European scientific exploration in the Southern Hemisphere. Further, an evaluation is made of the manner of the spread of new thought in the social sciences from the intellectual and cultural 'centre' of England and Europe to the Anglo-European community located at the 'periphery' in Australia in the late nineteenth century. In particular the educative role played by the non-professional enthusiast as a pivotal conduit for the dissemination of these ideas is highlighted and linked back to a significant tradition of amateur scholarship as a central phenomenon in the study of the history of ideas.
