I think that Plato's dialogs are well worth reading too.
Also, just so you know, Jesus is as or more historically "likely to be real" than Socrates (three major works written by two people who knew Him, multitudes more written by those who knew those who knew Him, mentions by multiple historians of the period, a thriving cult in spite of vicious persecutions, etc.). Socrates has three contemporaries (Plato, Xenophon, Aristophanes) and then the writings of Plato project him beyond his time and into the philosophical context.
But perhaps you mean "the Jesus of the Gospels" as opposed to "Yeshua ben Yoseph min Natzret" when you said "historic" here (there's good arguments for Jesus-of-the-Gospels being Yeshua ben Yoseph too, but one thing at a time).
