Former discussions of biological generalizations have focused on the question of whether there are universal laws of biology. These discussions typically analyzed generalizations out of their investigative and explanatory contexts and concluded that whatever biological generalizations are, they are not universal laws. The aim of this paper is to explain what biological generalizations are by shifting attention towards the contexts in which they are drawn. I argue that within the context of any particular biological explanation or investigation, biologists employ two (...) types of generations. One type identifies causal regularities exhibited by particular kinds of biological entities. The other type identifies how these entities are distributed in the biological world. (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)

Recent interest in the social and ethical aspects of biology raises the question of the disciplinary status of the study of these aspects of biology . In the traditional interpretations of theoretical biology the social and ethical aspects are usually not explicitly mentioned. In this article arguments are given for inclusion of the study of these aspects of biology within a broadened conception of theoretical biology.

This paper analyses the actual meaning of a transcendental philosophy of biology, and does so by exploring and actualising the epistemological and metaphysical value of Kant's viewpoint on living systems. It finds inspiration in the Kantian idea of living systems intrinsically resisting objectification, but critically departs from Kant's philosophical solution in as far as it is based in a subjectivist dogmatism. It attempts to overcome this dogmatism, on the one hand by explicitly taking into account the conditions of possibility at (...) the side of the subject, and on the other hand by embedding both the living and the knowing system into an ontology of complexly organized dynamical systems. This paper fits into the transcendental perspective in acknowledging the need to analyse the conditions of knowability, prior to the contents of what is known. But it also contributes to an expansion and an actualisation of the issue of transcendentality itself by considering the conditions of possibility at the side of the object as intrinsically linked to the conditions of possibility at the side of the subject.

This paper focuses on a running dispute between Werner Callebaut’s naturalistic view and Filip Kolen and Gertrudis Van de Vijver’s transcendentalist view on the nature of philosophy of biology and the relation of this discipline to biological sciences. It is argued that, despite differences in opinion, both positions agree that philosophy of biology’s ultimate goal is to ‘move’ biology or at least be ‘meaningful’ to it. In order to make this goal clear and effective, more is needed than a polarizing (...) debate which hardly touches upon biology. Therefore, a redirection in discussion is suggested towards a reflection on the possibilities of incorporating philosophy in interdisciplinary research, and on finding concrete research questions which are of interest both to the philosopher and to the biologist.

The impact of philosophy of science on biology is slight. Evolutionary biology, however, is nowadays an exception. The status of the neo-Darwinian theory of evolution is seriously challenged from a methodological perspective. However, the methodology used in the relevant discussions is plainly defective. A correct application of methodology to evolutionary theory leads to the following conclusions. The theory of natural selection is unfalsifiable in a strict sense of the term. This, however, does not militate against the theory, because no scientific (...) theory whatever is testable in this way. Under a more liberal testability criterion, the theory is surely testable. None the less, certain research programs may tend to make the theory untestable in practice. It has often been argued that the tautologous character of the principle of natural selection, allegedly the focus of evolutionary theory, makes the theory untestable through circular reasoning. Actually, the principle is only a tautology if ‘fitness’ is wrongly defined in terms of actual survival. But even then circular reasoning need not ensue. Evolutionary principles do not permit, without additional information, the derivation of statements about evolutionary events concerning particular species or populations. If this were a reason to criticize the theory , any other scientific theory would be inadequate by the same token. (shrink)

Several important analyses of the structure of evolutionary explanation have explicitly or implicitly required that historical laws be among the explanans statements. The required historical laws take the form of a generalization which relates some property or event to a developmental sequence of properties or events. The thesis of this paper is that historical laws of this kind are precluded by modern biological theory and, hence, analysis of evolutionary explanation within modern biology that require such laws are defective.

Revaluation of the problem of natural teleology seems an important precondition for elucidating our environmental crisis and for formulating an 'econological ethics', because it calls for a recognition of an intrinsic value in nature and organisms. Therefore, it is necessary to show that the concept of natural teleology is not in contradiction with scientific theories, in particular not with the theory of evolution. In this paper I shall argue that there is a fundamental misunderstanding about the concepts of teleology and (...) chance in modern thinking. This as a result of a radical transformation of the Aristotelian concept of teleology by Christian theologians during the Middle Ages. This confusion resulted in the rejection of teleology from evolution and in an exaggeration of the role of chance. However, not a solution for the problem of teleology is given here, but only an attempt to prove that neither the fossil-record, nor the role of chance in evolution can give adequate arguments for the negation of teleology in evolution. That is not to say that, therefore there exists teleology in evolution, but the problem of teleology in nature cannot, be solved by the scientific theory of evolution, but only be elucidated by philosophical analysis. At the end of the paper it is argued that teleology must be rather presupposed in evolution. (shrink)

The beginning of any rigorous interdisciplinary study, as Hegel and later Marx predicted, is going to be the occasion for opposition, contradiction, negation and mediation. Sociobiology is not a mature field (thesis). Kitcher's critical work entitledVaulting Ambition seeks to at once expose the failings of this field (serving as antithesis) while simultaneously defining the requirements for more mature, and thus epistemologically satisfying, sociobiological explanations (synthesis). The sociobiological research agenda is thus implicitly given a green light provided certain methodological precautions are (...) taken into consideration. Confucius believed that under these circumstances the only way to restore order would be so to arrange affairs that the Emperor would continue to be Emperor, the nobles to be nobles, the ministers to be ministers, and the common people common people. That is, the actual must in each case be made to correspond to the name. This theory Confucius called theRectification of Names (cheng ming), a doctrine which he recognized as being of the utmost importance. (Fung, 1952, p. 59). Tzu-lu said, “If the Lord of Wei left the adminstration (cheng) of his state to you, what would you put first?” The Master said, “If something has to be put first, it is, perhaps, the rectification (cheng) of names.” (The Analects (Lun yü) of Confucius, Book XIII: 3) (Besides being homophones, the two words in Chinese are cognate, thus showing that the concept of ‘governing’ was felt to be related to that of ‘correcting’.) .

This paper discusses the individuation of characters for the use asunits by geneticists at the beginning of the 20th century. Thediscussion involves the Presence and Absence Hypothesis as a case study. It issuggested that the gap between conceptual consideration and etiological factorsof individuating of characters is being handled by way of mutual adjustment.Confrontation of a suggested morphological unit character with experimentresults molded the final boundaries of it.

The main claim in this paper is that because organisms have teleological constitutions, the reduction of biology to physical science is not possible. It is argued that the teleology of organisms is intrinsic and not merely projected onto them. Many organic phenomena are end-oriented and reference to ends is necessary for explaining them. Accounts in terms of functions or goals are appropriate to organic parts and processes. siis is because ends as systemic requirements for survival and health have explanatory significance (...) with respect to the processes that contribute to and constitute them. Reductionism cannot accommodate this sort of higher-level to lower-level explanation and so cannot account for why lower-level phenomena are as they are. Reductionism, it is claimed, is ultimately descriptive and not explanatory because it cannot regard teleological requirements as themselves basic. In seeking to explain them away it forfeits explanatory power. (shrink)

This article argues, in opposition to a common interpretation of Wittgenstein deriving from Winch, that there is nothing especially problematic about the social sciences. Familiar Wittgensteinian theses about language, notably on the open-endedness of linguistic rules and on the importance of family resemblance concepts, have great relevance not only to the social sciences but also to much of the natural sciences. The differences between scientific and ordinary language are much less sharp than Winch, and probably Wittgenstein, supposed.

Biologists and philosophers have long recognized the importance of species, yet species concepts serve two masters, evolutionary theory on the one hand and taxonomy on the other. Much of present-day evolutionary and systematic biology has confounded these two roles primarily through use of the biological species concept. Theories require entities that are real, discrete, irreducible, and comparable. Within the neo-Darwinian synthesis, however, biological species have been treated as real or subjectively delimited entities, discrete or nondiscrete, and they are often capable (...) of being decomposed into other, smaller units. Because of this, biological species are generally not comparable across different groups of organisms, which implies that the ontological structure of evolutionary theory requires modification. Some biologists, including proponents of the biological species concept, have argued that no species concept is universally applicable across all organisms. Such a view means, however, that the history of life cannot be embraced by a common theory of ancestry and descent if that theory uses species as its entities.These ontological and biological difficulties can be alleviated if species are defined in terms of evolutionary units. The latter are irreducible clusters of reproductively cohesive organisms that are diagnosably distinct from other such clusters. Unlike biological species, which can include two or more evolutionary units, these phylogenetic species are discrete entities in space and time and capable of being compared from one group to the next.

Supervenience is a relationship which has been used recently to explain the physical determination of biological phenomena despite resistance to reduction. Supervenience, however, is plagued by ambiguities which weaken its explanatory value and obscure some interesting aspects of reduction in biology. Although I suspect that similar considerations affect the use of supervenience in ethics and the philosophy of mind, I don’t intend anything I have to say here to apply outside of the physical and biological cases I consider.The main point (...) of this paper is that there is a property of biological systems which makes it both misleading and inappropriate to reduce central biological phenomena to the properties of underlying components. Despite this, reductive explanation has been a major source of innovation in biological theory. The apparent tension can be resolved if underlying properties are explanatorily relevant to the higher level phenomena even though the latter are not strictly reducible to the former. Supervenience, I will argue, is not robust enough to deny reduction while supporting explanatory relevance. (shrink)

Abstract.In recent issues of Zygon, numerous reflections have been published commenting on where the field of science‐and‐religion has been, where it presently stands, and where it should move in the future. These reflections touch on the importance of the dialogue and raise questions as to what audience the dialogue addresses and whom it should address. Some scholars see the dialogue as prospering, while others point out that much work needs to be done to make the dialogue more accessible to a (...) larger audience and more successful at tackling the provocative questions before us. Other academics view the questions themselves as needing further consideration and focus before answers to them can even be explored. In this article I provide a general overview of these essays by outlining some general categories of thought that seem to emerge from the contributors. I then present some of my own opinions concerning the future of the science‐religion field and emphasize that the dialogue, in addition to its traditional roles, must further the philosophical framework that can aid humanity in resolving the most pressing global concerns of our time.

The theoretical system Lyell presented in 1830 was composed of three requirements or principles: 1) the Uniformity Principle which states that past geological events must be explained by the same causes now in operation; 2) the Uniformity of Rate Principle which states that geological laws operate with the same force as at present; 3) the Steady-state Principle which states that the earth does not undergo any directional change. The three principles form a single thesis called uniformitarianism which has been repeatedly (...) questioned and which has been reputed to be unable to face the competing directional synthesis based on the theory of the earth's cooling down. As a result, the significance of Lyell's system has been reduced to a simple actualism which admits the validity of the only Uniformity Principle. I believe that the only way to understand Lyell's role in the history of science is to maintain the unity of his synthesis. To show the Newtonian roots of this synthesis I will compare Lyell's principles and Newton's Rules of Reasoning. I will conclude with an analysis of the methodological function of principles in Lyell's scientific endeavour. (shrink)
