What is the main conflict of pamela in the story ? Is it internal or external

One of the great social facts of Richardson’s day was the intermingling of the aspirant middle class with the gentry and aristocracy. The eighteenth century was a golden age of social climbing and thereby of satire (primarily in poetry), but Richardson was the first novelist to turn his serious regard on class difference and class tension. Pamela’s class status is ambiguous at the start of the novel. She is on good terms with the other Bedfordshire servants, and the pleasure she takes in their respect for her shows that she does not consider herself above them; her position as a lady’s maid, however, has led to her acquiring refinements of education and manner that unfit her for the work of common servants: when she attempts to scour a plate, her soft hand develops a blister. Moreover, Richardson does some fudging with respect to her origins when he specifies that her father is an educated man who was not always a peasant but once ran a school.
