Abstract

Logic and linguistics have engaged in a many-faceted dialogue since the very beginnings of both disciplines in Antiquity. While participants may have had diverse views over the ages, arguably, the dialogue has always revolved around the relationship between human thought and natural language. While there are those who see these two domains as one and the same, or as a case of one-directional influence , we beg to differ. To us, the long historical tradition of authors such as Arnauld, Boole, Turing, or Jespersen demonstrates the much richer perspectives on language and reasoning that are needed, including connections with intelligence and computability.Another major historical theme in the above dialogue are similarities or convergences between natural and artificial languages. It is clear that natural languages are not only semantically broader, but also much closer to human communication than artificial languages, and so linguistic grammars have long dealt with a larger set of problems than logical formalism. This specal issue of JoLLI consists six selected papers presented in the "Logic and Linguisics" Workshop in UNI-LOG 2013 in Rio de Janeiro, plus two papers by invited authors: Johan van Benthem, and Marcus Kracht and Uno Klein. It contains a number of samples of what is intriguing and promising work at the interfaces of logic and language.
