“It appears that the act of extension, in whatever sector it takes place, means that those carrying it out need to go to “another part of the world” to “normalize it,” according to their way of viewing reality: to make it resemble their world. Thus, in its “field of association” the term extension has a significant relation to transmission, handing over, giving, messianism, mechanical transfer, cultural invasion, manipulation, etc. All these terms imply actions which transform people into “things” and negate their existence as beings who transform the world.”

–Paolo Freire from “Extension or Communication,” 1974
