Rooke makes several important observations about the slaves, though he misses several others. He understands first that language is something that ties people together, which shows that he's moving away from his solitary studies of Greek and Latin. He also now understands firsthand that people are people, regardless of the color of their skin—essentially, he realizes that white people aren't “superior” to black people. However, this new understanding doesn't force Rooke to take a look at his own involvement in the imperialist military, the force that's currently helping keep the slave trade alive.
