The analogy Darwin drew between artificial and natural selection in "On the Origin of Species" has a detailed structure that has not been appreciated. In Darwin’s analogy, the kind of artificial selection called Methodical selection is analogous to the principle of divergence in nature, and the kind of artificial selection called Unconscious selection is analogous to the principle of extinction in nature. This paper argues that it is the analogy between these two different principles familiar from his studies of artificial (...) selection and the two different principles he claims are operative in nature that provides the main structure and force of the analogy he uses to make his case for the power of natural selection to produce new species. Darwin’s statements explicitly distinguishing between these two kinds of principles at work in nature occur prominently in the text of the Origin. The paper also shows that a recent revisionist claim that Darwin did not appeal to the efficacy of artificial selection is mistaken. (shrink)

This chapter determines a major empirical hurdle for any future discipline of memetics. It mainly shows that one can find very similar copies of some cultural item, link these copies through a causal chain of events which faithfully reproduced those items, and nevertheless not have an example of memetic inheritance. In addition, the stability of cultural patterns is proof that fidelity in copying is high despite individual variations. It is also believed that what is offered as an explanation is precisely (...) what needs to be explained; what is offered as a solution is in fact the very problem to be solved. Moreover, the issue is whether the relative stability observed in cultural transmission is proof of replication. The example of the acquisition of language is briefly addressed. The Darwinian model of selection is informative, and in various ways, for thinking about culture. Imitation is of course well worth investigating. On the other hand, the grand project of memetics is misled. (shrink)

The diversity, complexity and adaptation of the biological realm is evident. Until Darwin, the best explanation for these three features of the biological was the conclusion of the “argument from design.” Darwin's theory of natural selection provides an explanation of all three of these features of the biological realm without adverting to some mysterious designing entity. But this explanation's success turns on the meaning of its central explanatory concept, ‘fitness’. Moreover, since Darwinian theory provides the resources for a purely causal (...) account of teleology, wherever it is manifested, its reliance on the concept of ‘fitness’ makes it imperative that conceptual problems threatening the explanatory legitimacy of this notion be solved.

Theories of business ethics or corporate responsibility tend to focus on justifying obligations that go above and beyond what is required by law. This article examines the curious fact that most business ethics scholars use concepts, principles, and normative methods for identifying and justifying these beyond-compliance obligations that are very different from the ones that are used to set the levels of regulations themselves. Its modest proposal—a plea for a research agenda, really—is that we could reduce this normative asymmetry by (...) borrowing from the normative framework of “regulation” to identify and justify an important range of beyond-compliance obligations. In short, we might think of “self-regulation” as a language and a normative framework with some distinct advantages over other frameworks like stakeholder theory, corporate social responsibility, corporate citizenship, and the like. These other frameworks have been under attack in the business ethics literature of late, primarily for their vagueness and their disappointing inability to distinguish clearly between genuine beyond-compliance moral obligations, on the one hand, and charitable acts that are laudable but not morally obligatory, on the other.

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.

We suggest that human culture exhibits key Darwinian evolutionary properties, and argue that the structure of a science of cultural evolution should share fundamental features with the structure of the science of biological evolution. This latter claim is tested by outlining the methods and approaches employed by the principal subdisciplines of evolutionary biology and assessing whether there is an existing or potential corresponding approach to the study of cultural evolution. Existing approaches within anthropology and archaeology demonstrate a good match with (...) the macroevolutionary methods of systematics, paleobiology, and biogeography, whereas mathematical models derived from population genetics have been successfully developed to study cultural microevolution. Much potential exists for experimental simulations and field studies of cultural microevolution, where there are opportunities to borrow further methods and hypotheses from biology. Potential also exists for the cultural equivalent of molecular genetics in “social cognitive neuroscience,” although many fundamental issues have yet to be resolved. It is argued that studying culture within a unifying evolutionary framework has the potential to integrate a number of separate disciplines within the social sciences. (shrink)

Critics of Darwinian cultural evolution frequently assert that whereas biological evolution is blind and undirected, cultural change is directed or guided by people who possess foresight, thereby invalidating any Darwinian analysis of culture. Here I show this argument to be erroneous and unsupported in several respects. First, critics commonly conflate human foresight with supernatural clairvoyance, resulting in the premature rejection of Darwinian cultural evolution on false logical grounds. Second, the presence of foresight is perfectly consistent with Darwinian evolution, and is (...) found in biology, in the form of open, teleonomic processes such as genetically-biased behavioural learning. Finally, empirical evidence from the social sciences suggests that cultural change appears far less guided and directed, and human foresight far less accurate, than is commonly assumed. (shrink)

Godfrey-Smith ( 2001 ) has distinguished three types of adaptationism. This article builds on his analysis, and revises it in places, by distinguishing seven varieties of adaptationism. This taxonomy allows us to clarify what is at stake in debates over adaptationism, and it also helps to cement the importance of Gould and Lewontin’s ‘Spandrels’ essay. Some adaptationists have suggested that their essay does not offer any coherent alternative to the adaptationist programme: it consists only in an exhortation to test adaptationist (...) hypotheses more thoroughly than was usual in the 1970s. Here it is argued that the ‘Spandrels’ paper points towards a genuinely non-adaptationist methodology implicit in much evolutionary developmental biology. This conclusion helps to expose the links between older debates over adaptationism and more recent questions about the property of evolvability. (shrink)

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.

ABSTRACT:There is considerable overlap between the interests of business ethicists and those of political philosophers. Questions about the moral justifiability of the capitalist system, the basis of property rights, and the problem of inequality in the distribution of income have been of central importance in both fields. However, political philosophers have developed, especially over the past four decades, a set of tools and concepts for addressing these questions that are in many ways quite distinctive. Most business ethicists, on the other (...) hand, consider their field to be primarily a domain of applied ethics, and so adopt methods and conceptual frameworks developed by moral philosophers. In this paper, we discuss some of the salient differences between these two approaches, and suggest some ways in which business ethicists could benefit from taking a more “political philosophy” approach to these questions. Throughout, we underline the importance of seeking greater compatibility among the principles used in normative theorizing about markets, regulations, corporate governance, and business practices.

So-called grand or paradigmatic theories—structural functionalism, psychoanalysis, Marxism, rational-choice theory—provide their proponents with a conceptual vocabulary and syntax that allows for the classification and configuring of wide ranges of phenomena. Advocates for any particular “analytical grammar” are accordingly prone to conflating the internal coherence of their paradigm—its integrated complex of definitions, axioms, and inferences—with a corresponding capacity for representational verisimilitude. The distinction between Theory-as-heuristic and Theory-as-imposition is of course difficult to negotiate in practice, given that empirical observation and measurement are (...) not entirely “theory neutral” or independent of prior analytical conceptualization. Nonetheless, the scientific cogency of any theory is ultimately evaluated by the substantive realism of its foundational assumptions and categorical designations; that is, the accuracy with which it identifies and tracks the determinant properties and processes of the phenomena to be explicated. The paradigm of sociocultural evolutionism—despite extensive revamping by contemporary proponents—does not carry warrant in this regard, as its recourse to an analytical grammar fashioned and derived from another discipline raises doubts about its empirical veridicality. This article revisits the contentious issue of remodeling social phenomena in accordance with biological categories and offers both a theoretical and a substantive critique of the “selectionist” paradigm. The transdisciplinary program of historical social science is affirmed by way of counterpoint. (shrink)

In his historical perspective on the changes in scientific thought over the last 100 years, Carl N. Degler explores the study of social evolution and the ongoing search for human nature. In Search of Human Nature provides a detailed perspective on the reasons behind the shifting emphasis in social thought from biology, to culture, and again to biology. Degler examines why these changes took place, the evidence and people fostering these changes and why students of human nature decided to accept (...) this momentous change in thought. He suggests varying ideologies as the underlying force behind this shift in the study of social science. From Darwin's theory that human social behaviour has drastically evolved from animals, to the belief that human experience serves as the basic differentiating factor in humans, Degler provides a thorough and captivating examination of the roots of human behaviour.

Tim Lewens aims to understand what it means to take an evolutionary approach to cultural change, and why it is that these approaches are sometimes treated with suspicion. While making a case for the value of evolutionary thinking for students of culture, he shows why the concerns of sceptics should not dismissed as mere prejudice, confusion, or ignorance. Indeed, confusions about what evolutionary approaches entail are propagated by their proponents, as well as by their detractors. By taking seriously the problems (...) faced by these approaches to culture, he shows how such approaches can be better formulated, where their most significant limitations lie, and how the tools of cultural evolutionary thinking might become more widely accepted.

The debate over the relative importance of natural selection as compared to other forces affecting the evolution of organisms is a long-standing and central controversy in evolutionary biology. The theory of adaptationism argues that natural selection contains sufficient explanatory power in itself to account for all evolution. However, there are differing views about the efficiency of the adaptation model of explanation. If the adaptationism theory is applied, are energy and resources being used to their optimum? This book presents an up-to-date (...) view of this controversy and reflects the dramatic changes in our understanding of evolution that have occurred in the last twenty years. The volume combines contributions from biologists and philosophers, and offers a systematic treatment of foundational, conceptual, and methodological issues surrounding the theory of adaptationism. The essays examine recent developments in topics such as phylogenetic analysis, the theory of optimality and ess models, and methods of testing models. (shrink)

This book asks whether evolution can help us to understand human behaviour and explores diverse evolutionary methods and arguments. It provides a short, readable introduction to the science behind the works of Dawkins, Dennett, Wilson and Pinker. It is widely used in undergraduate courses around the world.

Darwinizing culture: the status of memetics as a science pits leading intellectuals, against each other to battle it out, in this, the first debate over 'memes'. With a foreword by Daniel Dennett, and contributions from Dan Sperber, David Hull, Robert Boyd, Susan Blackmore, Henry Plotkin, and others, the result is a thrilling and challenging debate that will perhaps mark a turning point for the field, and for future research.

Darwin himself suggested the idea of generalizing the core Darwinian principles to cover the evolution of social entities. Also in the nineteenth century, influential social scientists proposed their extension to political society and economic institutions. Nevertheless, misunderstanding and misrepresentation have hindered the realization of the powerful potential in this longstanding idea. Some critics confuse generalization with analogy. Others mistakenly presume that generalizing Darwinism necessarily involves biological reductionism. This essay outlines the types of phenomena to which a generalized Darwinism applies, and (...) upholds that there is no reason to exclude social or economic entities. (shrink)

Debate about adaptationism in biology continues, in part because within “the” problem of assessing adaptationism, three distinct problems are mixed together. The three problems concern the assessment of three distinct adaptationist positions, each of which asserts the central importance of adaptation and natural selection to the study of evolution, but conceives this importance in a different way. As there are three kinds of adaptationism, there are three distinct "anti-adaptationist" positions as well. Or putting it more formally, there are three different (...) dimensions here, and strongly adaptationist views, strongly anti-adaptationist views, and moderate views are possible for each dimension.
