Nowadays philosophy is characterized by such heterogeneous intellectual practices that its very unity and coherence seem endangered. What is especially disconcerting is that most authors manage to largely ignore the very existence of methodological positions radically different from their own. Fortunately, there have been exceptions, and the present volume focuses on one of them: the failed debate that took place between John Searle and Jacques Derrida. This book thoroughly analyses that exchange, contextualizing it within the respective philosophical traditions of the two thinkers, with the general aim of turning their dispute into what it was not: a respectful, sensible and fruitful controversy. This episode is thus taken as an opportunity to reflect on the peculiar nature of philosophy as an intellectual practice, and to discuss some of its main themes: language as an instrument for communication, the intentionality of consciousness, and difference as a constitutive element of every text.
