McLuhan did. But McLuhan asked it in a way that 
called it to everyone’s attention, and that I think is 
an enormous contribution that he’s made to 
scholarship, and especially to me.

And I’d add that there probably is not a 
communications department in any college or 
university in America that does not reflect in some 
way, McLuhan’s question. McLuhan’s answers, 
which you’ll find all over the place in Understanding  
Media , are sometimes interesting, sometimes I think 
they may be irresponsible, and sometimes just 
wrong, but that never bothered me and I don’t 
think it should bother students who read McLuhan.
