Human nature has always been a foundational issue for philosophy. What does it mean to have a human nature? Is the concept the relic of a bygone age? What is the use of such a concept? What are the epistemic and ontological commitments people make when they use the concept? In What’s Left of Human Nature? Maria Kronfeldner offers a philosophical account of human nature that defends the concept against contemporary criticism. In particular, she takes on challenges related to social (...) misuse of the concept that dehumanizes those regarded as lacking human nature (the dehumanization challenge); the conflict between Darwinian thinking and essentialist concepts of human nature (the Darwinian challenge); and the consensus that evolution, heredity, and ontogenetic development results from nurture and nature. After answering each of these challenges, Kronfeldner presents a revisionist account of human nature that minimizes dehumanization and does not fall back on outdated biological ideas. Her account is post-essentialist because it eliminates the concept of an essence of being human; pluralist in that it argues that there are different things in the world that correspond to three different post-essentialist concepts of human nature; and interactive because it understands nature and nurture as interacting at the developmental, epigenetic, and evolutionary levels. On the basis of this, she introduces a dialectical concept of an ever-changing and “looping” human nature. Finally, noting the essentially contested character of the concept and the ambiguity and redundancy of the terminology, she wonders if we should simply eliminate the term “human nature” altogether.

Over the last four decades arguments for and against the claim that creative hypothesis formation is based on Darwinian ‘blind’ variation have been put forward. This paper offers a new and systematic route through this long-lasting debate. It distinguishes between undirected, random, and unjustified variation, to prevent widespread confusions regarding the meaning of undirected variation. These misunderstandings concern Lamarckism, equiprobability, developmental constraints, and creative hypothesis formation. The paper then introduces and develops the standard critique that creative hypothesis formation is guided (...) rather than blind, integrating developments from contemporary research on creativity. On that basis, I discuss three compatibility arguments that have been used to answer the critique. These arguments do not deny guided variation but insist that an important analogy exists nonetheless. These compatibility arguments all fail, even though they do so for different reasons: trivialisation, conceptual confusion, and lack of evidence respectively. Revisiting the debate in this manner not only allows us to see where exactly a ‘Darwinian’ account of creative hypothesis formation goes wrong, but also to see that the debate is not about factual issues, but about the interpretation of these factual issues in Darwinian terms.

Continuing Franz Boas' work to establish anthropology as an academic discipline in the US at the turn of the twentieth century, Alfred L. Kroeber re-defined culture as a phenomenon sui generis. To achieve this he asked geneticists to enter into a coalition against hereditarian thoughts prevalent at that time in the US. The goal was to create space for anthropology as a separate discipline within academia, distinct from other disciplines. To this end he crossed the boundary separating anthropology from biology (...) in order to secure the boundary. His notion of culture, closely bound to the concept of heredity, saw it as independent of biological heredity (culture as superorganic) but at the same time as a heredity of another sort. The paper intends to summarise the shifting boundaries of anthropology at the beginning of the twentieth century, and to present Kroeber?s ideas on culture, with a focus on how the changing landscape of concepts of heredity influenced his views. The historical case serves to illustrate two general conclusions: that the concept of culture played and plays different roles in explaining human existence; that genetics and the concept of Weismannian hard inheritance did not have an unambiguous unidirectional historical effect on the vogue for hereditarianism at that time; on the contrary, it helped to establish culture in Kroeber's sense, culture as independent of heredity.

The article addresses the question whether culture evolves in a Lamarckian manner. I highlight three central aspects of a Lamarckian concept of evolution: the inheritance of acquired characteristics, the transformational pattern of evolution, and the concept of directed changes. A clear exposition of these aspects shows that a system can be a Darwinian variational system instead of a Lamarckian transformational one, even if it is based on inheritance of acquired characteristics and/or on Lamarckian directed changes. On this basis, I apply (...) the three aspects to culture. Taking for granted that culture is a variational system, based on selection processes, I discuss in detail the senses in which cultural inheritance can be said to be Lamarckian and in which sense problem solving, a major factor in cultural change, leads to directed variation.

This article illustrates in which sense genetic determinism is still part of the contemporary interactionist consensus in medicine. Three dimensions of this consensus are discussed: kinds of causes, a continuum of traits ranging from monogenetic diseases to car accidents, and different kinds of determination due to different norms of reaction. On this basis, this article explicates in which sense the interactionist consensus presupposes the innate?acquired distinction. After a descriptive Part 1, Part 2 reviews why the innate?acquired distinction is under attack (...) in contemporary philosophy of biology. Three arguments are then presented to provide a limited and pragmatic defense of the distinction: an epistemic, a conceptual, and a historical argument. If interpreted in a certain manner, and if the pragmatic goals of prevention and treatment are taken into account, then the innate?acquired distinction can be a useful epistemic tool. It can help, first, to understand that genetic determination does not mean fatalism, and, second, to maintain a system of checks and balances in the continuing nature?nurture debates. (shrink)

Charles Darwin und seine Erben wendeten die Theorie der Evolution biologischer Arten auch auf Kultur an. Kultur evolviere wie die Natur auf Darwinistische Weise. Die sog. Memtheorie, vertreten von verschiedenen Autoren auf der Basis des Darwinistischen Genselektionismus, ist eine Spielart einer solchen analogen Anwendung. Dieser Artikel kritisiert drei zentrale Aussagen der Memtheorie: (i) dass es Einheiten der Kultur – Meme – gibt, die analog zu Genen zu verstehen sind, (ii) dass Meme, in Analogie zu Genen, Replikatoren sind, und (iii) dass (...) Meme als Einheiten der kulturellen Selektion auf die gleiche Art wie Gene 'egoistisch' sein können. Nach einer Einführung in die Memtheorie in Teil 1, werden diese drei Thesen in Teil 2 als entweder falsch oder trivial entlarvt. Dieser kritische Teil soll vor allem zeigen, dass die Memtheorie keine 'gefährliche Idee' ist, die das bisher in den Geistes- Kultur- und Sozialwissenschaften tradierte Verständnis von Geist und Kultur herausfordern kann. Im Gegenteil, im besten Fall re-formuliert die Memtheorie lediglich Bekanntes in evolutionärer Sprache und ist in diesem Sinne trivial. In Teil 3 wird die Perspektive gewechselt: Nicht mehr der Gehalt, sondern die Funktion der Memtheorie, v.a. im Kontext interdisziplinärer Verständigung, soll betrachtet werden. Denn trotz der Kritik der drei Kernthesen kann die Memtheorie eine kommunikative und somit produktive Rolle zwischen den 'zwei Kulturen' der Wissenschaften spielen. (shrink)
