You're off-base here. Fuzzy logic is still precise; some confusion arises from the fact that "fuzzy logic" has become a colloquialism meaning "illogic."

I can assure you that fuzzy logic (in the technical sense used in the article) does not mean "hey, let's fudge some assumptions so that we can jam these statements together."

By the way, I'd recommend learning a little about fuzzy logic. Very interesting stuff.

I actually haven't studied fuzzy logic, but I'd guess this is the explanation for the example used in the article:

Question: Statement P, "This statement is false," has what truth value?

Let t = the truth value of P. Note that t also equals the truth value of ~P, which is 1 - t. So t = 1 - t, so t = .5
