A conjecture (seems easy to prove):

"If, in a fuzzy logic where truth values range from [0,1], we allow logical operators (which are maps from [0,1] to [0,1]) or predicates that does not intersect the slope=1 line, then we can always construct a Liar's Paradox."

An example is the binary predicate "less-than", which has a discontinuity at 0.5 and hence does not intersect the y=x line.
