The more substantial argument is based on the anti-Socratic sentiment. It is difficult at first to answer why Socrates would be criticized by his student and follower. While it was thought that the confusion of "Clitophon's" authorship began with the Aldine Press editions of Plato's works, the 1491 Ficino translations say that this work was not Plato's. This indication was from Greek manuscripts, which did not clearly state the author of "Clitophon". Schleiermacher was one of the first to lead people to characterize "Clitophon" as spurious; while he acknowledges its listing in the Platonic corpus, he could not reconcile the non-Socratic sensitivity. It seems improbable for the author to not be Plato, for he is not intending to criticize the historical Socrates, but to create an example of a person not understanding Socrates through the reproach of literary Socrates.
