Around fuzziness. Some philosophical thoughts

Fuzzy logic has a considerable success in the area of applications. However, this active growth in the implementation in applied electronic devices has not always been accompanied by a discussion about the theoretical grounds underlying those uses. This paper deals with some theoretical aspects that seem convenient to discuss for the purpose of clarifying the status of fuzzy logic, to get into its true nature and to appoint its achievements and limits. In order to carry out this goal, the paper is organized around three questions: 1) Fuzzy logic, is it a logic or a techno-logic?; 2) How fuzzy is fuzzy computing?; 3) Are there fuzzy objects?
