Fuzzy logic includes 0 and
1 as extreme cases of truth (or "the state of matters" or "fact") but
also includes the various states of truth in between so that, for example, the result of a comparison
between two things could be not "tall" or "short" but ".38 of
Fuzzy logic seems closer to the way our brains work. We aggregate data and form a number of partial truths which we aggregate further into higher truths which in turn, when certain thresholds are exceeded, cause certain further results such as motor reaction.
