For instance, he describes the Platonists as being on good terms with this very Alexander of Abonoteichos whom he is ridiculing and exposing.

He appeals to Celsus to say whether a certain work of Epicurus is not his finest.

He says that his friend will be pleased to know that one of his objects in writing is to see justice done to Epicurus.

All these expressions Dr.Keim thinks may be explained as the quiet playful irony that was natural to Lucian, and from other indications in the work he concludes that Lucian's Celsus may well have been a Platonist, though not a bigoted one, just as Lucian himself was not in any strict and narrow sense an Epicurean.
When once the possibility of the identification is conceded, there are, as Dr.Keim urges, strong reasons for its adoption.

The characters of the two owners of the name Celsus, so far as they can be judged from the work of Origen on the one hand and Lucian on the other, are the same.
