Once social change begins, it cannot be reversed. You cannot uneducate the person who has learned to read. You cannot humiliate the person who feels pride. You cannot oppress the people who are not afraid anymore. We have seen the future, and the future is ours.
-Cesar Chavez

this is saying that education is good because people now know what people are talking about when they say something or when something is said to them people are aware of what the future is going to be.
