The consensus among evolutionists seems to be that the morphological complexity of organisms increases in evolution, although almost no empirical evidence for such a trend exists. Most studies of complexity have been theoretical, and the few empirical studies have not, with the exception of certain recent ones, been especially rigorous; reviews are presented of both the theoretical and empirical literature. The paucity of evidence raises the question of what sustains the consensus, and a number of suggestions are offered, including the (...) possibility that certain cultural and/or perceptual biases are at work. In addition, a shift in emphasis from theoretical to empirical inquiry is recommended for the study of complexity, and guidelines for future empirical studies are proposed. (shrink)

In this paper I claim that the goal of mapping and sequencing the human genome is not wholly new, but rather is an extension of an older project to map genes, a central aim of genetics since its birth. Thus, the discussion about the value of the HGP should not be posed in global terms of acceptance or rejection, but in terms of how it should be developed. The first section of this paper presents a brief history of the project. (...) The second section distinguishes among four kinds of issues relevant to an evaluation of the HGP: those economic and organizational issues related to the feasibility of the project; the ethical questions arising in the development of the project and the application of the data gathered; the empirical issues relevant to the scientific value of the project; and conceptual issues like reductionism and determinism relevant to understand the nature and scope of the project. In a third section, I analyze in detail whether the HGP and, more generally, molecular biology is reductionistic. (shrink)

Western society has been diverted from the goal of spiritual freedom and autonomy as expressed in the ancient Pythagorean 'theory of the cosmos'. Indeed, following Heidegger's analysis, it can be seen that modern Western society has arrived at the opposite pole of anthropocentric 'absolute subjectivism' in which the entire non-human world is seen as a material resource to be consumed in the satisfaction of our egoistic passive desires. It is further argued that Spinozism is actually a modern version of the (...) 'theory of the cosmos' which, when supplemented by a vision of man's identity with the ecological world, would provide us with the only adequate portrayal of the God/Nature/Man relationship.

Mendelian genes have become molecular genes, with increasing puzzlement about locating them, due to increasing complexity in genomic webworks. Genome science finds modular and conserved units of inheritance, identified as homologous genes. Such genes are cybernetic, transmitting information over generations; this too requires multi-leveled analysis, from DNA transcription to development and reproduction of the whole organism. Genes are conserved; genes are also dynamic and creative in evolutionary speciation—most remarkably producing humans capable of wondering about what genes are.

The Red Queen hypothesis, or the ability organisms have to control and regulate the available trophic energy, is a recently proposed parameter for measuring fitness. Firstly, this hypothesis is analysed in terms of its heuristic power. Secondly, the claimed causal dependence between this parameter and a, still controversial, law of constant extinction is judged to be unjustified, however reasonable such a claim appears to be. Finally, the ubiquity of competition in nature which is seemingly required by the Red Queen and (...) supposedly realized at the expense of a mutualistic alternative, is deemed to be a questionable assumption.

For several decades, economists have been preoccupied with an attempt to place their entire subject on the ‘sound microfoundations’ of general equilibrium theory, with its individualistic premises. However, this project has run into seemingly intractable problems. This essay examines underlying questions such as the appropriate building block of analysis and the structure of explanation in economics. The examination of biology is found to be instructive, due to debates concerning the limitations of reductionism within that discipline. The final part of the (...) paper argues for the autonomy of a non‐reductionist macroeconomics, based on the institution as the unit of analysis. (shrink)

Classifying is a fundamental operation in the acquisition of knowledge. Taxonomic theory can help students of cognition, evolutionary psychology, ethology, anatomy, and sociobiology to avoid serious mistakes, both practical and theoretical. More positively, it helps in generating hypotheses useful to a wide range of disciplines. Composite wholes, such as species and societies, are “individuals” in the logical sense, and should not be treated as if they were classes. A group of analogous features is a natural kind, but a group of (...) homologous features is not. Imposing hypotheses justified only on the basis of nominalist, realist, phenomenalist, or conceptualist metaphysics upon the neurophysiology of organisms or upon the causes of behavior exemplifies the “psychologist's fallacy” of William James. Levels should be distinguished from their members and from classes of levels, and the ontological status of entities ranked at levels should be made clear. It is important not to confuse such categories as substance and process with one another. Several genetical terms, such as “gene” and chromosome,” are even more equivocal than has been realized. Discussions about units of selection, behavior, and thinking suffer from the ambiguity of a “unit of” an entity. An important source of misunderstanding about natural selection is the habit of treating it as an “agent”: in an important sense, natural selection does not “act” at all. (shrink)
