But since it won’t last more than a day, I can’t imagine Socrates regarding the trial as fair, regardless of the outcome.
Update: Patrick writes to say that Socrates was acquitted, though the vote by the audience was relatively narrow (55-45). His expertise was employed by both sides, as befits a "philosopher."
