The theories of Marshall McLuhan and Neil Postma

Compare the theories of Marshall McLuhan (the medium as the message) and Neil Postman (the medium as the metaphor), as presented in Klassen's text (pp. 174-175). In 1-2 paragraphs, summarize these and highlight the important differences between them. Then, in an additional paragraph (or 2, if needed), demonstrate which of the two you find more convincing, in light of the relation of these theories to the forms of religiosity Klassen explores in this chapter.
