Objectivism attempts to understand human knowledge in impersonal terms. One of the most important features of literacy is that it allows people to think impersonally. As we have seen, oral people inevitably understand the world in personal terms, since for them communication is always tied to an actually existent, and present, person.
Writing dissolves the immediate link between a person and his or her words and thus allows the reader to understand words, and thus reality generally, in an impersonal fashion.
