This work is intended to offer to anyone still intending to devote himself to the Socratic problem a reliable means of approach by providing, first of all, a complete history of the problem itself, from its first appearance during Socrates' lifetime up to the present day. The book provides not only the history of the problem, but also the essential documents, accompanied by brief explana-tory and bibliographical contextual notes, to be read in counterpoint with the chapters of its history. These documents consist of 61 extracts from 54 authors, from Fréret onwards, in other words, from the beginning of the history of the problem of the socratic sources, which arose in the Age of Enlightenment, down to the present day. These extracts are not intended to form a collection of the various representations, interpretations or images of Socrates which succeeded each other in the history of socratic historiography; instead, the aim is to present, in a logically and chronologically consistent order, the various ways in which the problem of the sources of Socratism was presented and resolved in the course of two hundred years of study and research on the 'case' of Socrates.
