Logic, Intelligence and Artifices

This volume is a homage to the computer scientist and philosopher

Tarcísio Haroldo Cavalcante Pequeno. Tarcísio dedicated his research

to subjects ranging from logic to philosophy through artificial

intelligence, theoretical computer science and language. His main

contributions were in nonmonotonic and paraconsistent logics,

especially the study of negation; algebraic approaches to the semantics

of programming languages, applications of intuitions from game

semantics to automatic theorem proving; tableaux methods for

paraconsistent logics and the role of rule following and rule

consciousness in cognition, motivated by his interest in philosophy

and the problem of demarcation of rationality.



The contributions to this volume reflect the broad range of interests characteristic of

Tarcísio's scientific interests. Topics include relations between

logic and category theory, specifications of model checkers,

philosophy of paraconsistent logics, epistemic logic, abstract

argumentation semantics, natural language processing, foundations of

mathematics, philosophical aspects of natural language processing,

philosophy of logic and language, metaphysics, philosophy of science.



During the last forty years, Tarcísio oriented, inspired and

collaborated with many researchers and established the field of logic

as an active research area in Northeast Brazil. This book expresses

the admiration of his colleagues and the recognition of his influence

on their academic lives.
