A variety of new theories have been developed on the basic principles of neutrosophy: among them is neutrosophic logics, a family of many-valued systems that can be regarded as a generalization of fuzzy logics. In this paper we present a critical introduction to neutrosophic logics, focusing on the problem of defining suitable neutrosophic propositional connectives and discussing the relationship between neutrosophic logics and other well-known frameworks for reasoning with uncertainty and vagueness, such as (intuitionistic and interval-valued) fuzzy systems and Belnap’s logic.eninfo:eu-repo/semantics/openAccessjournal articleNeutrosophic logicsNeutrosophyMany-valued logicsFuzzy logicsIntuitionistic fuzzy logicBelnap’s logic
