Two mathematicians in Greece have recently made some promising work on solving self-referential sentences using fuzzy logic (e.g. This sentence is false, or Everything I say is a lie). Instead of the usual mathematical chaos that ensues while trying to solve such non-linear systems of equations, they have borrowed from control theory to find consistent solutions without such chaos.
