At the risk of sounding like a broken record, I'll repeat my opinion on 
the subject:

I like Tribus' definition of information as "anything that causes a 
change in probability assignment", because it emphasizes the organic 
relation that information theory bears to probability theory. My trite 
analogy for the situation --

   Info-theory : prob theory = diff calc : algebra.

Cheers,
