    Definition

    In this work a comparison is attempted between the Aristotle’s traditional bivalent logic, which dominated for centuries on the human way of thinking, and the relatively recent Zadeh’s fuzzy logic, which has already found many and important applications to almost all sectors of the human activity. It is concluded that, although the enormous progress of science and technology owes a lot to bivalent logic, fuzzy logic which completes and extends it, fits much better to our everyday life situations and to the scientific way of thinking.

    1. Introduction

    Logic is understood to be the study of the correct reasoning, involving the drawing of inferences. There is no doubt that the enormous progress of science and technology owes a lot to the Aristotle’s (384-322 BC, Figure 1) bivalent logic, which dominated for centuries the human way of thinking.
