Presentation gives context for the content. Go ahead and look through a
complex table presented as plain-text with footnotes crammed inline and
you'll see that while it may technically put the content on the screen,
it doesn't present the full idea before the reader.
Even looking at html with only basic formatting can do the same. Compare:
http://www.ccel.org/ccel/schaff/anf09.iii.iii.html
to the original. Start at page 10 here:
http://books.google.com/books?id=ApMsAAAAYAAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
Note that you should be looking at two pages side-by-side. It is much
easier to grasp the full concept in the original book.
There is a reason why formatting has been important for centuries now.
