Written vs Spoken

Lemke said that spoken language falls before we have a chance to analyze it, but written language is forever.  I find it interesting the distinct difference made between spoken and written language. With spoken language more “mistakes” can be made because they are likely to be missed and forgotten about, only the main ideas will remain. On the other hand, written language has the ability to be analyzed again and again word for word. This seems to connect to the idea of how stories in Africa were once told compared to how they are told now. Before stories were all oral, they involved motions and emotions and were passed down through memory, but once the European colonizers arrived stories began to be written down. While now there is a “formal” way to write down the stories, what is lost from the oral traditions of the past? Telling a story from memory is a certain kind of literacy, it just seems to be less respected by the European world because it can not be analyzed or monitored in the same way as written stories can be. While written language is incredibly important what is really gained if the written and the spoken are completely different?
