Yitay, the term “???? ?????” is in a grammatical form called
“??????”. Thus, it means “the wisdom of Greek”. From the Gemara and Rashi it seems that it was a form a rhetoric. It may have referred to the methods of the Sophists, who were accused of deception – hence the English word “sophistry”.
BTW, there is a joke about a bachur who finds a Tanach in hte bet midrash. He shows it to his chevruta and says “Look! Someone collected all of the pesukim in Shas into one book.”
