It is also thought that the growth of the middle class and a growth in the number of scribes needed for the expanded bureaucracy under Senusret II helped spur the development of Middle Kingdom literature.[1] Later ancient Egyptians considered the literature from this time as "classic".[51] Stories such as the Tale of the Shipwrecked Sailor and the Story of Sinuhe were composed during this period, and were popular enough to be widely copied afterwards.[51] Many philosophical works were also created at this time, including the Dispute between a man and his Ba where an unhappy man converses with his soul, The Satire of the Trades in which the role of the scribe is praised above all other jobs, and the magic tales supposedly told to the Old Kingdom pharaoh Khufu in the Westcar Papyrus.[51]
