M’Leod here envisions a new “race” of Irish citizens whose interests, indeed whose “hearts,” are firmly aligned with those of the Ascendancy class
One of two views on the role of education in the novel: perhaps novel is advocating for education so that native Irish can stand on equal (or somewhat equal) footing with their colonial administrators and engage in mutually beneficial conversation as a result. Or, as this article says, raise the Irish to be good members of a colonized class. Maybe a little of both. Maybe the two are inextricable?
