Gaia, teleologia e função

Episteme 11 (23):15-48 (2006)

Abstract
Neste artigo, discutimos o papel das explicações teleológicas na teoriaGaia. Mostramos que seu principal proponente, James Lovelock, pretendeevitá-las devido a uma interpretação equivocada da natureza de taisexplicações. Na tentativa de evitar compromissos com a teleologia,Lovelock recorre ao conceito de propriedades emergentes. Esta não é,contudo, uma saída consistente, porque os conceitos de propriedadesemergentes e teleologia não são mutuamente excludentes. Discutimostambém as dificuldades de uma interpretação de Gaia de uma perspectivateleonômica, considerando problemas como o da noção de superorganismo.Para avaliar o estatuto das explicações teleológicas em Gaia, examinamoso caso da interação entre algas e nuvens, que resultou num novo campo depesquisas e expõe as contribuições teóricas e empíricas que Gaia podeoferecer. Com base nos argumentos apresentados ao longo do artigo,sugerimos uma reorganização da estrutura do programa de pesquisa Gaia,visando à continuação de seu progresso teórico e empírico.In this paper, we discuss the role of teleological explanations in Gaia theory.We show that its main proponent, James Lovelock, intends to avoid themdue to a misinterpretation of the nature of teleological explanations. Inorder to avoid a commitment to teleology, Lovelock appeals to the conceptof emergent properties. This is not a consistent solution, however, since the concepts of emergent properties and teleology are not mutuallyexclusive. We also discuss difficulties in an interpretation of Gaia from ateleonomic perspective, discussing problems such as that of the notion ofsuperorganism. In order to appraise the status of teleological explanationsin Gaia, we examine the case of the interaction between algae and clouds,which gave birth to a new research field and show the theoretical andempirical contributions that Gaia can bring. Based on the argumentsdeveloped in the paper, we suggest a reorganization of the structure ofGaia research program, in order to go on with its theoretical and empiricalprogress
