This book contains eight long essays, which have never been published in English and which offer a highly original reconstruction of the different elements of Platonic thought, starting with reflections on the writing techniques invented by Plato. Two dialogues, the Phaedrus and the Statesman, are analysed in depth, while an analysis of the Apology of Socrates serves to challenge the traditional vision of Socratic dialogues. The two final essays are devoted to methodological questions, which on the one hand reaffirm the need to respect the letter of the text, and on the other hand present a completely innovative hermeneutic proposal: the multifocal approach.
