Um Embrião não é um Indivíduo

Palavras-chave: Aborto, Ontologia Pessoal, Metafísica Modal, Filosofia da Biologia

Resumo

Um argumento recorrente contra a liberalização do aborto parte do pressuposto de que, desde o momento da fertilização, seres humanos são indivíduos (no sentido de serem algo que necessariamente ocorre em uma entidade apenas). Nesse artigo, parto da possibilidade de geminação monozigótica e do fato de identidades serem necessárias para argumentar que esse não é o caso. No artigo, discuto as premissas do argumento e as possíveis interpretações de sua conclusão. Argumento que a conclusão desse argumento está em concordância com a conclusão de um argumento semelhante, que parte de noções correntes de ‘organismo’.
