This research focuses specifically on the examination of scenes of extreme alterity between children and adults, with the aim of demonstrating the way in which these scenes help to construct a vision of language as a form of life, managing to reject universalism as well as relativism, favouring instead a perspectivist understanding. Ludwig Wittgenstein s writings post-Tractatus Logico-Philosophicus, a work he completed in his younger years, are more often than not interpreted with a way of thinking which tends towards relativism and which directly contradicts the first work of the philosopher, most commonly interpreted as a work that tends towards universalism. This research points towards a singular philosophy, in terms of the interpretation put forward by Brazilian researcher and philosopher Bento Prado Jr., according to whom the telos of Wittgensteinian philosophy has never wavered. Thereby, neither universalism nor relativism are contemplated in the Wittgensteinian thinking, rather a perspective philosophy, comparable in certain aspects to the philosophy of, for example, Nietzsche and Deleuze. For a better understanding of perspectivism in Wittgenstein s philosophy, in harmony with the research project that we have adhered to, an analysis of what can be called scenes of radical alterity in Wittgenstinian writing has been undertaken – a type of thought experiment that occurs with great frequency in the late work of the philosopher. This appears in the form of imaginary scenes which depict encounters, perplexities and misunderstandings between savage and civilised individuals, crazy and sane individuals, easterners and westerners, children and adults, and so on. In these experiments, the rigour of Wittgenstein s critical work on language and meaning manifests itself, ever concomitant to his criticism of metaphysics. This work has been centered on the identification and analysis of scenes relating to adult versus child alterity, by assuming that the concept of childhood may be extended in relation to the chronological period with which it is frequently associated, as Italian philospher Giorgio Agamben proposes. The examination of such scenes has allowed the investigation into the extent to which this alterity works as an indication of perspectivism in the late writings of Wittgenstein and the extent to which the scenes of alterity illustrate the Wittgensteinian idea of the form of life. In order to understand the elusive notion of form of life according to Wittgenstein, we also must not avoid the ties to anthropology – the central questions of which are demonstrably present in the writings of the Viennese philosopher. In doing this, we give privilege to the ethnophilosophical work of anthropologist Eduardo Viveiros de Castro. The analysis of the Wittgensteinian corpus, coupled with the ethnophilosophy of Viveiros de Castro, indicates points of convergence between Wittgensteinian thought – and that of perspectivist philosophers in general – and Amerindian cosmology such as that presented by Viveiros de Castro. The research carried out sheds light on a Wittgensteinian form of perspectivism, the singular forms with which the philosopher allows the existance multiple worlds in the basic rejection of the idea of a world vision, in the implosion of the subject/object partition, in the ties between philosophy and poetry.
