I don't agree with that assumption because I believe more people now have access to information then they have in the past, whether or not if it is being filtered or not filtered. The media literacy was much more limited in the past and the intellects were few and far in between. Sure, people who were fortunate enough to be educated have the opportunity to be more literate and thus have more channels to get information to learn. But now more people have the opportunity compared to the number of people in the past and now, I think you"ll find that telegraphically epistemology has improved our literacy and it has been a help to our culture and society since its invention. .
There is another statement by Postman that I strongly disagree with. "There is no beginning, middle, or end in a world of photographs" (Postman 74). I believe that photographs can tell many stories, from beginning to middle to end. Granted that not all photographs will do that but some do. Postman's statement suggest that all photographs are certain way and that is a very strong generalization and he does that quite often through out the book in my opinion. Pictures have been used since ancient days to communicate ideas, stories, and thoughts and in my opinion photographs are pictures and they convey some of the same principles as it has in the past, maybe in different format but same idea.
In the second part of the book Postman deals with television as show business, particularly the news media, television as teaching tools and its effects, and his suggestion of how we might be able to avoid the effect of television.
Postman writes, " television offers viewers a variety of subject matter, requires minimal skills to comprehend it, and is largely aimed at emotional gratification" (86). I agree with his statement here. I think television is satisfying to the eye and mind because we can put the picture to the idea.
