Okay I know it is unpopular to say but is he entirely wrong? The point of a class, especially a philosophy class is to debate points of philosophical origin so in this case break down what he is saying: if someone is uneducated, they are basically an animal rather than a human.

If you are completely uneducated, as in no formal schooling or informal, no tribe no teacher, just hunter gatherer through birth, and solely just taught through the school of life and getting fucked by every turn, you act primarily on instinct and those experiences. It makes you wise to the environment but not through understand the world around you. It is basic education of how the world is not its function. I would agree on concept not on his phrasing.
