Socrates is concluding the argument with both boys which combines the arguments he had had with them separately. With Lysis, the Philon is not of like with like, with Menexenus, the Philon is not of opposite with opposite, with both, the Philon is of the not like and not opposite (i.e, the neutral) with the good. This apparently successful outcome agreed to by both boys is a dismal failure for Socrates, and he will have to try harder to rouse them out of their stupor.
