What is the True Value of Fuzzy Reasoning in the Framework of the ‘Human Intelligence’ Linguistic Variable?

Computations are presented in the framework of ‘human intelligence’ linguistic variable. Computation concern fuzzy reasoning i.e. the true value of the implication 'IF…THEN'. Computation reveal high dependence of the true value of a rule on the meaning of fuzzy logic operator 'IF…THEN'. The effect of the incorporation of different kind of understanding of the fuzzy logic expression ‘Intelligent’ in the premises of fuzzy reasoning is presented. This framework makes it possible that in cardiology “severe” and “moderate” pathology may be both be “true “for a given patient.
