Pluralism and Ambivalence in the Evolution of Morality

Much good work has been done on the evolution of human morality by focusing on how “selfish genes” can give rise to altruistic human beings. A richer research program is needed, however, to take into account the ambivalence of naturally evolved biopsychological motivators and the historical pluralism of human morality in religious systems. Such a program is described here. A first step is to distinguish the ultimate cause of natural selection from proximate causes that are the results of natural selection. Next, some proximate causes are suggested as possible conditions of biological and emotional valuing as well as of customary social morality and individual rational ethical thought. Finally, different moral perspectives of Confucianism, Hinduism, Buddhism, and Christianity are briefly presented in order to illustrate how one might inquire about the selection of a variety of biopsychological and cultural proximate causes that enable the evolution of a plurality of religious moral systems.

What Does It Mean to Be Human? A Personal and Catholic Perspective

A philosopher-poet-theologian ponders the implications of the multimillion-year biogenetic process that produced Homo sapiens and is beginning to reveal itself ever more clearly as evolution of the mind and consciousness. As meaning trappers and makers, called to actualize the divine image imprinted upon us, we are now facing biological and cultural evolution with deliberate human input as well as the evolution of evolution. As communicating animals that are becoming ever more aware of our adaptive behavior, we have the potential of affecting our own destiny by listening to the spirit within and nurturing the genes and memes that give rise to physical, intellectual, creative, and moral excellence. In the matrix of cyberspace we have the opportunity to heal the two-culture split, to reinvent ourselves, to incubate/weave the emergent religions of the future, and to create our multiple "Ways" appropriate to the dawning Age of Global Dialogue.     

TAKING PRAGMATISM SERIOUSLY: A REVIEW OF WILLIAM BAUM'S UNDERSTANDING BEHAVIORISM: BEHAVIOR,CULTURE, AND EVOLUTION (SECOND EDITION)

This important book has two main purposes. The first is to present, in a non‐technical way, accessible to intelligent laypeople, a scientific, behavioral approach to all aspects of human activity including choice, rule‐governed behavior, self control, religious belief, linguistic interaction, ethics, and culture. Its scope equals that of Skinner's nontechnical writings, but Baum's approach is more molar and more pragmatic than Skinner's. The book's second purpose is to embed behavioral science firmly in the context of Darwinian evolution. Baum is generally successful, we believe, in both of these ambitious purposes.     

The role of feature type and causal status in 4–5-year-old children's biological categorizations

The present study investigated the role of the causal status of features and feature type in biological categorizations by young children. Study 1 showed that 5-year-olds are more strongly influenced by causal features than effect features; 4-year-olds exhibit no such tendency. There therefore appears to be a conceptual change between the ages of 4 and 5 in the evaluation of the causal relations between features that characterize biological categories. The aim of Study 2 was to identify the nature of the abstract beliefs that underlie children's categorial choices. Results show that 5-year-olds base category choices on causal features only when the status of the cause is associated with an internal feature and not if the feature is merely a surface feature. Children thus use biological knowledge to perform the task.     

Blocking a selective association in pigeons

Experiment 1 demonstrated for the first time a stimulus-reinforcer interaction in pigeons trained with free-operant multiple schedules of reinforcement. Pigeons that treadle pressed in the presence of a tone-light (TL) compound for food exhibited primarily visual stimulus control on a stimulus-element test, whereas pigeons that avoided shock in TL exhibited auditory control. In Experiment 2, this selective association was blocked in pigeons pretrained with the biologically contingency-disadvantage element of the compound (i.e., tone-food or light-shock) before TL training. When this pretraining preceded compound-stimulus training, control was now auditory in pigeons that treadle pressed for food and was visual in pigeons that avoided shock. Previous attempts at blocking this selective association were unsuccessful in pigeons (LoLordo, Jacobs, & Foree, 1982) but were successful in rats (Schindler & Weiss, 1985). Experiment 2 established that selective associations can be blocked in pigeons when the procedures that were effective with rats were systematically replicated. These results further demonstrate the cross-species generality of an associative attentional mechanism involving a biological constraint on learning in species with different dominant sensory systems.     

The Biological Function Paradigm Applied to the Immunological Self-Non-Self Discrimination: Critique of Tauber's Phenomenological Analysis

Biological self reference idioms in brain-centered or nervous-system-centered self determination of the consious Self reveal an interesting contrast with biological self-determination by immunological self/non-self discrimination. This contrast is both biological and epistemological. In contrast to the consciousness conscious of itself, the immunological self-determination imposes a protective mechanism against self-recognition (Coutinho et al. 1984), which adds to a largely unconscious achievement of the biological Self (Popper 1977; Medawar 1959). The latter viewpoint is in contrast with the immunological Self-determination as an essentially cognitive process as expressed in the analysis of Tauber (1994). Comparison of the immune system in vertebrates and invertebrates, according to new biological insights, has contributed to a better understanding of the relative role of innate (or inherited) immunity versus immunity acquired during each individual life. Also in this respect, immunological self-achievement shows both a striking analogy and a fundamental discrepancy with the activity of the nervous system. The analysis of immunological Self/non-self discrimination versus brain-centered self-determination adds to the understanding of the function paradigm in biological self-reference idioms, especially when regarding the importance of the connectivity notion in both systems. Adopting functional explanatory schemes for understanding immunological self-non-self discrimination, as well as for the understanding of functional mapping of the brain at (conscious) activity (Friston et al. 1993; Frith et al. 1995), forwards the notion of effective/functional connectivity. Network connectivity not only is a primary question in solving the dimensionality question for immunological ‘idiotypic networks’ (Jerne 1974a, b; 1984), it may also have an important value in describing phase transitions in the development of both immune and nervous systems.

Patenting humans: Clones,chimeras, and biological artifacts

The momentum of advances in biology is evident in the history of patents on life forms. As we proceed forward with greater understanding and technological control of developmental biology there will be many new and challenging dilemmas related to patenting of human parts and partial trajectories of human development. These dilemmas are already evident in the current conflict over the moral status of the early human embryo. In this essay, recent evidence from embryological studies is considered and the unbroken continuity of organismal development initiated at fertilization is asserted as clear and reasonable grounds for moral standing. Within this frame of analysis, it is proposed that through a technique of Altered Nuclear Transfer, non-organismal entities might be created from which embryonic stem cells could be morally procured. Criteria for patenting of such non-organismal entities are considered. An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights and Patents,” held in Warsaw, Poland on 23–24 April, 2004.
