dmb,

Are you an either/or - black/white thinker, because I recognize a whole lot of shades of gray in-between those extremes.  Unless you want to define cold as below freezing and hot above freezing, which might contradict experience, I don't think your example works.  

I think the term is relative as in "relatively pure".

Logical operations can easily be used on opposed terms like "hot and cold", for example, but then what do you do with "warm"? Hot is defined as not cold and cold is defined as not hot, so fuzzy logic is the logic used to express degrees of "truth" or degrees of inclusion in the set called "cold" or "old" or "rich". There are lots of vague terms, context dependent terms or relational terms in the language and so fuzzy logic is invented to handle these terms with a more complicated form of logic.
