HOW DOES THE TEILHARDIAN VISION OF EVOLUTION COMPARE WITH CONTEMPORARY THEORIES?

Abstract. Teilhard de Chardin's ideas about the mechanisms of biological evolution are revised and their connections with contemporary theories are reported. Teilhard de Chardin's main contribution is the proposal of a new scientific discipline, geobiology—the science of the biosphere evolving as a whole. The main fields of interest of geobiology are reported, and its relationships with contemporary hypotheses, such as Lovelock's Gaia, are discussed. The consequences of this kind of approach are the parallel evolution described as orthogenesis and the presence of canalization phenomena. These Teilhardian hypotheses are discussed in relation to those of the process structuralists and to the novelties of the molecular evolution of the genome. Conclusions are that the mechanisms discussed by Teilhard are presently taken into consideration by contemporary evolutionists in order to construct a new theory of biological evolution.     

Is Biosphere Doing Theology?

Three theories about evolution are presently under discussion: the genocentric theory, the organismocentric theory, and the biospherocentric theory. A brief discussion of the three theories is presented. These theories have different implications for theology. The genocentric theory is related to the Darwinian interpretation and, for theology, means the end of an apologetic vision of natural science and for this reason the end of natural theology. The organismo-centric theory is mainly related to events of autoorganization and follows the path of the geometrical harmony of nature. But it is far different from the apologetic interpretation of natural theology which cannot be restored. The biospherocentric theory, on the contrary, contains many fruitful perspectives. This theory, which counts Teilhard de Chardin among its founders, allows the development of a new approach to the theology of nature. In this approach, it is actually the biosphere herself that is doing theology thanks to her thinking sphere: the noosphere.     

RELATIONSHIPS BETWEEN SCIENTIFIC ANALYSIS AND THE WORLD VIEW OF PIERRE TEILHARD DE CHARDIN

Abstract. This paper introduces the thought of Pierre Teilhard de Chardin from a perspective neglected until now: a view that builds on the analysis of his scientific papers. His scientific work formed part of the "modern synthesis" which laid the foundation of contemporary Darwinism. His main contributions in the field were the definition of a new branch of evolutionary sciences, geobiology; the redefinition of the term orthogenesis ; and the proposal of the "scale" phyletic tree. Using these new research concepts, Teilhard de Chardin attempted to solve, within a scientific framework, a problem fundamental for his philosophical synthesis: that of evolutionary directionality.
