In this chapter we will try to show how the introduction of Darwinian evolutionary theory transformed metaphysics, and in particular, the philosophical understanding of the temporality of being. In the interests of brevity, we will focus on two particularly significant aspects of the impact of Darwinism on Latin America. We will consider, first, how the new evolutionary thought transformed past notions of temporality. Second, we will discuss the ways in which the ideas of regression and extinction, viewed as essential components (...) of the evolutionary process, problematized the nature of progress and civilization. We trace these developments in the work of three central figures of Latin American thought: José Martí, José Rodó, and Euclides da Cunha. All three of these men were extraordinarily versatile thinkers, and each has been the subject of voluminous secondary literature. But the first two, unlike some other influential figures—such as, famously, Domingo Sarmiento of Argentina—were hardly self-professed Darwinians. Still, we have chosen to discuss them because of this last fact, and not despite it. As for da Cunha, though he accepted the basic canons of the new evolutionary theory, he remained ambivalent about its application. All three struggled, each in his own way, to come to terms with the Darwinian legacy, and each found his thinking profoundly shaped by this struggle; they offer us three different, unique perspectives on the impact of Darwinism. The magnitude of the new evolutionism can only be understood if we consider the wide range of discussion it triggered in consequence of its profound philosophical impact. (shrink)
