Aristotle in the dock: the prologue to Jeronimo Muñoz' Libro del Nuevo Cometa

Abstract

The epistolary prologue to Jeronimo Muñoz Libro del nuevo cometa ( 1573) is the first resolute refutation of the Aristotelian paradigm in Spain. lt is primarily a rhetorical procedure: the Valencian astronomer and hebraist makes use of elaborated argumentative and stylistic strategies that create the image of an 'Aristotle in the dock' who, at the end of the discourse, is declared guilty of ignorance with respect to astronornic subjects. ln that way, Mufloz creates an argumentative basis for propagating his new cosmology. An analysis of the central passages of this historic refutatio not only reveals the importance of rhetoric in the scientific discourse of the Spanish golden age, but also its central role in the process of a paradigm shift in the scientific world view.
