kinds of things in there: we had all the corrections 
and the fiddly stuff going on; we also started a 
whole bunch of new chapters on all the new 
technologies. And in these new chapters we 
started to present these statements and that 
made them a little different from the earlier 
chapters which were in essay form. The minute 
we’d asked the question about, “What general 
statements can you make about all media that 
anyone can test for themselves, or that anyone 
can go out and find the answers for themselves?” 
And doing that, asking that question, lead to our 
discovering over a period of several weeks a series 
of four general statements that people can make.
