Abstract.Stuart Kauffman's work on complexity and self‐organization echoes ideas found in writings of C. S. Peirce and G. W. F. Hegel. Included in these common threads are the understanding of science as historical narrative, the recognition of emergence as a phenomenon associated with complex systems, and the appreciation of agency as an emergent property that serves as both a creative and determining force in evolution.

Nietzsche’s attitude toward science is ambivalent: he remarks approvingly on its rigorous methodology and adventurous spirit, but also points out its limitations and rebukes scientists for encroaching onto philosophers’ territory. What does Nietzsche think is science’s proper role and relationship with philosophy? I argue that, according to Nietzsche, philosophy should set goals for science. Philosophers’ distinctive task is to ‘create values’, which involves two steps: (1) envisaging ideals for human life, and (2) turning those ideals into prescriptions for behaviour and (...) societal organization. To accomplish step (2), philosophers should delegate scientists to investigate what moral rules and social arrangements have best advanced this ideal in the past or might in the future. (shrink)

This paper presents a pilot study in the "epidemiological" program for cultural research put forward by Dan Sperber. Theory is offered to argue that verse form is so disabling that its worldwide distribution must be explained by functions other than the broad communicative, or ideological, power traditionally attributed to it. The theoretical case is confirmed by numerical data showing that in matched texts of English prose and verse the latter contain words of a lower mean length (measured in syllables). Candidate (...) hypotheses for the epidemiology of verse are offered, including design for mnemonic properties, the registration of differences in verbal intelligence, the presentation of gestures of commitment, and the introduction of levels of quasi-randomness that lead to an impression of semantic richness and the illusion of profound and powerful communication.

Selectionism addresses the process of transition or change. In its evolution, Homo Sapiens has demonstrated such transitions to more hierarchically complex stages of performance at the individual, organizational, cultural, and biological levels. Traditionally, changes in biological, cultural, organizational, and individual behavior have been studied separately, with very little overlap. The current theory integrates selectionism across these realms, while noting that in each, selectionism operates through somewhat different mechanisms. Selectionism is comprised of complex processes in which tasks of greater hierarchical complexity (...) may be selected. Increased stages of performance underlie evolution's dynamics of increased complexity. (shrink)

Evolutionary moral realism is the view that there are moral values with roots in evolution that are both specifically moral and exist independently of human belief systems. In beginning to sketch the outlines of such a view, we examine moral goods like fairness and empathetic caring as valuable and real aspects of the environments of species that are intelligent and social, or at least developing along an evolutionary trajectory that could lead to a level of intelligence that would enable individual (...) members of the species to recognize and respond to such things as the moral goods they in fact are. We suggest that what is most morally interesting and important from a biological perspective is the existence and development of such trajectories, rather than the position of one particular species, such as our own, on one particular trajectory.

I argue that our general disposition to make moral judgments and our core moral intuitions are likely the product of social selection—a kind of gene–culture coevolution driven by the enforcement of collectively agreed-upon rules. Social selection could potentially track mind-independent moral truth by a process that I term realist social selection: our ancestors could have acquired moral knowledge via reason and enforced rules based on that knowledge, thereby creating selection pressures that drove the evolution of our moral psychology. Given anthropological (...) evidence that early humans designed rules with the conscious aim of preserving individual autonomy and advancing their collective interests, the theory of realist social selection appears to be attractive for moral realists. The goal of evolutionary debunking arguments should be to show not that our moral beliefs are the product of natural selection, but that realist social selection did not occur. (shrink)

In 1975, the English evolutionist William Donald Hamilton held in Brazil a series of lectures entitled “Population genetics and social behaviour”. The unpublished notes of these conferences—written by Hamilton and recently discovered at the British Library—offer an opportunity to reflect on some of the author’s ideas about evolution. The year of the conference is particularly significant, as it took place shortly after the applications of the Price equation with which Hamilton was able to build a model that included several levels (...) of selection. In this paper I mainly analyse the inaugural lecture in which Hamilton proposes a simple model to disprove the hypothesis supported by the British zoologist C. Vero Wynne-Edwards regarding mechanisms to prevent “over-exploitation of the food supply” in “the interests of the survival of the group”. The document presented here is of great historical interest. Not only because manuscript offers a model that—since it was intended for teaching purposes—had never before appeared in the published version, but also because of the general index of the lectures that accompanies it. The latter allows us to make some hypothetical considerations on the relationship and differences between kin-selection, group-selection and inclusive fitness that Hamilton wanted to present to the attentive, well-prepared audience of the foreign university that had invited him.

This response outlines more reasons why we need the integrative framework of grandparental investments and intergenerational transfers that we advocated in the target article. We discusses obstacles that stand in the way of such a framework and of a better understanding of the effects of grandparenting in the developed world. We highlight new research directions that have emerged from the commentaries, and we end by discussing some of the things in our target article about which we may have been wrong.

What motivates grandparents to their altruism? We review answers from evolutionary theory, sociology, and economics. Sometimes in direct conflict with each other, these accounts of grandparental investment exist side-by-side, with little or no theoretical integration. They all account for some of the data, and none account for all of it. We call for a more comprehensive theoretical framework of grandparental investment that addresses its proximate and ultimate causes, and its variability due to lineage, values, norms, institutions (e.g., inheritance laws), and (...) social welfare regimes. This framework needs to take into account that the demographic shift to low fecundity and mortality in economically developed countries has profoundly altered basic parameters of grandparental investment. We then turn to the possible impact of grandparental acts of altruism, and examine whether benefits of grandparental care in industrialized societies may manifest in terms of less tangible dimensions, such as the grandchildren's cognitive and verbal ability, mental health, and well-being. Although grandparents in industrialized societies continue to invest substantial amounts of time and money in their grandchildren, we find a paucity of studies investigating the influence that this investment has on grandchildren in low-risk family contexts. Under circumstances of duress there is converging evidence that grandparents can provide support that helps to safeguard their children and grandchildren against adverse risks. We conclude by discussing the role that grandparents could play in what has been referred to as Europe's demographic suicide. (shrink)

Is one of the roles of theory in biology answering the question “What is life?” This is true of theory in many other fields of science. So why should not it be the case for biology? Yet efforts to identify unifying concepts and principles of life have been disappointing, leading some (pluralists) to conclude that life is not a natural kind. In this essay I argue that such judgments are premature. Life as we know it on Earth today represents a (...) single example and moreover there is positive evidence that it may be unrepresentative of life considered generally. Furthermore, as I discuss, the prototype for theorizing about life has traditionally been based on multicellular plants and animals. Yet biologists have discovered that the latter represent a rare, exotic, and fairly recent form of Earth life. By far the oldest, toughest, most extensive, and diverse form of life on our planet is unicellular, prokaryotic microbes, and there are reasons to suppose that this is almost certainly true elsewhere in the universe as well. If there are explanatorily and predictively powerful, biologically distinctive principles for life that can be gleaned from our insular example of life it is more likely that they will be found among the microbes. I discuss some provocative ways in which unicellular microbes differ from multicellular eukaryotes and argue that some of them just might provide us with key insights into the nature of life.

Do multi-level selection explanations of the evolution of social traits deepen the understanding provided by single-level explanations? Central to the former is a mathematical theorem, the multi-level Price decomposition. I build a framework through which to understand the explanatory role of such non-empirical decompositions in scientific practice. Applying this general framework to the present case places two tasks on the agenda. The first task is to distinguish the various ways of suppressing within-collective variation in fitness, and moreover to evaluate their (...) biological interest. I distinguish four such ways: increasing retaliatory capacity, homogenising assortment, and collapsing either fitness structure or character distribution to a mean value. The second task is to discover whether the third term of the Price decomposition measures the effect of any of these hypothetical interventions. On this basis I argue that the multi-level Price decomposition has explanatory value primarily when the sharing-out of collective resources is `subtractable'. Thus its value is more circumscribed than its champions Sober and Wilson (1998) suppose. (shrink)

Optimization models have often been useful in attempting to understand the adaptive significance of behavioral traits. Originally such models were applied to isolated aspects of behavior, such as foraging, mating, or parental behavior. In reality, organisms live in complex, ever-changing environments, and are simultaneously concerned with many behavioral choices and their consequences. This target article describes a dynamic modeling technique that can be used to analyze behavior in a unified way. The technique has been widely used in behavioral studies of (...) insects, fish, birds, mammals, and other organisms. The models use biologically meaningful parameters and variables, and lead to testable predictions. Limitations arise because nature's complexity always exceeds our modeling capacity. (shrink)

Altruism is a deep and complex phenomenon that is analysed by scholars of various disciplines, including psychology, philosophy, biology, evolutionary anthropology and experimental economics. Much confusion arises in current literature because the term altruism covers variable concepts and processes across disciplines. Here we investigate the sense given to altruism when used in different fields and argumentative contexts. We argue that four distinct but related concepts need to be distinguished: (a) psychological altruism , the genuine motivation to improve others’ interests and (...) welfare; (b) reproductive altruism , which involves increasing others’ chances of survival and reproduction at the actor’s expense; (c) behavioural altruism , which involves bearing some cost in the interest of others; and (d) preference altruism , which is a preference for others’ interests. We show how this conceptual clarification permits the identification of overstated claims that stem from an imprecise use of terminology. Distinguishing these four types of altruism will help to solve rhetorical conflicts that currently undermine the interdisciplinary debate about human altruism. (shrink)

This is a review article of Paul Cillier's 1999 book _Complexity and Postmodernism_. The review article is generally encouraging and constructive, although isolates a number of areas in need of clarification or development in Cillier's work. The volume of the _South African Journal of Philosophy_ in which the review article appeared also printed a response by Cilliers.

Although the theory of memetics appeared highly promising at the beginning, it is no longer considered a scientific theory among contemporary evolutionary scholars. This study aims to compare the genealogy of memetics with the historically more successful gene-culture coevolution theory. This comparison is made in order to determine the constraints that emerged during the internal development of the memetics theory that could bias memeticists to work on the ontology of meme units as opposed to hypotheses testing, which was adopted by (...) the gene-culture scholars. I trace this problem back to the diachronic development of memetics to its origin in the gene-centered anti-group-selectionist argument of George C. Williams and Richard Dawkins. The strict adoption of this argument predisposed memeticists with the a priori idea that there is no evolution without discrete units of selection, which in turn, made them dependent on the principal separation of biological and memetic fitness. This separation thus prevented memeticists from accepting an adaptationist view of culture which, on the contrary, allowed gene-culture theorists to attract more scientists to test the hypotheses, creating the historical success of the gene-culture coevolution theory.

Science’s theory of evolution purports to explain life and its historical dynamics in a physics/material-only fashion. But this entails a broad reliance on DNA (deoxyribonucleic acid) for inheritance (and thus blueprints), which appears to be implausible for a number of unusual innate behaviors. The immediate unfolding challenge, though, is that the inheritance role is conveniently testable via searches for the DNA origins of a number of human behavioral and health tendencies, and despite enormous efforts those searches have thus far largely (...) failed (i.e., the “absolutely beyond belief” missing heritability problem). This existing case for DNA’s inadequacies will be briefly reviewed herein. The subsequent main analysis considers some big challenges facing DNA associated with some evolutionary dynamics—the acquisition of color vision in primates; instinctive behaviors including the egg-laying practices of emerald jewel wasps; kin selection; and our natural religious beliefs. Together these challenges strongly suggest that the acceptance of DNA as the (complete) language of life was premature. The haphazard and ambiguous nature of DNA/genetic specifications is very unlikely to have provided a vehicle for the exacting blueprints required for the many instinctive behaviors or capacities. Life appears to be more complex than biologists believe. Two possible alternative explanations are briefly considered in the wake of these discussions. Finally, does anyone—beginning with academics—care about this unfolding foundational failure? (shrink)

The case of the Arabian babblers is a controversial and significant one in ethology that troubles standard sociobiological theories of the evolution of behaviour. In this chapter from her book Naissance d'une théorie éthologique, Vinciane Despret examines the divergent models and methods of the scientists studying the babblers, their different epistemologies and ontologies that are only truly visible and understandable if one takes into account their particular ways of comporting themselves with the birds, and the babblers’ active role in writing (...) their own scripts. In so far as it resembles the immersive participation and individual biographing of anthropological and primatological methods, and pays skilful attention to the reasons for their actions, Zahavi's way of relating to and questioning the babblers gives them the opportunity to respond.

It is widely assumed that human learning and the structure of human languages are intimately related. This relationship is frequently suggested to derive from a language-specific biological endowment, which encodes universal, but communicatively arbitrary, principles of language structure (a Universal Grammar or UG). How might such a UG have evolved? We argue that UG could not have arisen either by biological adaptation or non-adaptationist genetic processes, resulting in a logical problem of language evolution. Specifically, as the processes of language change (...) are much more rapid than processes of genetic change, language constitutes a both over time and across different human populations, and, hence, cannot provide a stable environment to which language genes could have adapted. We conclude that a biologically determined UG is not evolutionarily viable. Instead, the original motivation for UG arises because language has been shaped to fit the human brain, rather than vice versa. Following Darwin, we view language itself as a complex and interdependent which evolves under selectional pressures from human learning and processing mechanisms. That is, languages themselves are shaped by severe selectional pressure from each generation of language users and learners. This suggests that apparently arbitrary aspects of linguistic structure may result from general learning and processing biases deriving from the structure of thought processes, perceptuo-motor factors, cognitive limitations, and pragmatics.

The field of information technology is broadened up to the domain of ‘learning’ systems and cybernetics. In covering this extension of the field due recourse is made to the epistemological basis of theory construction. When so comprehended, information technology becomes a philosophical inquiry on a variety of social, scientific and technological issues. A new idea that we refer to as neuro-cybernetics is born. The term neuro-cybernetics is used to delineate the epistemological field of system and cybernetic study. The above-mentioned phenomenological (...) or the epistemic model of a cybernetic and system type is applied to flood control problem in Bangladesh. This example presents an application of the cybernetic model to a physico-human problem. This is the nature of socio-scientific system. In it, organically unifying relations occur between the environment and the human world, with the objective of controlling the perennial problem of floods by using interactive factors. (shrink)

Starting from Denis Noble’s criticism on the modern synthesis, this article argues that the author’s presentation of the modern synthesis focusses too one-sidedly on the phenomenal characteristics of the living, whereby it is made easily suitable to his criticisms, but risks to remain trapped in a territory-struggle; this criticism lacks an explicit focus on logical matters, and more in particular on the synthetic principles required to situate the relevancy or irrelevancy of phenomenal characteristics beyond territory-struggles. A brief sketch of how (...) the principle of teleology calls for reflexivity allows us to reveal the tension in Noble’s account between, on the one hand, the way in which he stresses the importance of metaphors and language, and, on the other hand, the way in which he invokes empirical arguments to assess the illusory character of certain metaphors.

Rational analysis (Anderson 1990, 1991a) is an empiricalprogram of attempting to explain why the cognitive system isadaptive, with respect to its goals and the structure of itsenvironment. We argue that rational analysis has two importantimplications for philosophical debate concerning rationality. First,rational analysis provides a model for the relationship betweenformal principles of rationality (such as probability or decisiontheory) and everyday rationality, in the sense of successfulthought and action in daily life. Second, applying the program ofrational analysis to research on human reasoning (...) leads to a radicalreinterpretation of empirical results which are typically viewed asdemonstrating human irrationality.
