About the Journal




The JOURNAL OF NON-CLASSICAL LOGIC (JNCL) was founded in 1982 by the Centre for Logic, Epistemology and the History of Science (CLE) of the State University of Campinas (UNICAMP), as the first journal totally devoted to the area of non-classical logics.


JNCL published during almost 10 years, sponsored by FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo), many higher quality articles in the areas of logic, philosophical logic and applications of non-classical logics. Fourteen numbers, in eight volumes, have been published due to the efforts of its editors, in chronological order, Newton C.A. da Costa, José Alexandre D. Guerzoni, Luiz Paulo de Alcantara and Itala M. Loffredo D'Ottaviano, actively assisted by members of the Editorial Board.


In 1991, independently but inspired by JNCL, the JOURNAL OF APPLIED NON-CLASSICAL LOGICS (JANCL) began to be published by Editions Hermès – Paris, edited by Luis Fariñas del Cerro at Toulouse.


Since JNCL and (JANCL) had similar scope, the two publishing groups agreed in 1991 to a fusion of both publications: JNCL and (JANCL) started to be published together, under the latter name, starting in 1992. The editorial board of the new journal incorporated Walter A. Carnielli, Newton C.A. da Costa, Itala M. Loffredo D'Ottaviano and Edgard G.K. López-Escobar.


The importance of JNCL can be also measured by its pioneering character, recognizing the relevance of the new paradigms of non-classical logic to philosophy, linguistics and to the formal sciences, with special emphasis to computer science.


The quality of the articles published, as well as its role as a forum for promoting research in contemporary logic, confer to JNCL a distinguished position in the history of publications in logic, and this fully justifies the production of the present content.
