Abstract

To represent and reason about moving objects in three-dimensional space qualitatively, we need a right fundamental logic system to provide us with a criterion of logical validity for reasoning as well as a formal representation language. In order to reason about new spatio-temporal knowledge with incomplete or sometime even inconsistent knowledge, the fundamental logic must be able to underlie relevant and truth-preserving reasoning in the sense of conditional, ampliative reasoning, paracomplete and paraconsistent reasoning, and spatio-temporal reasoning. This paper proposes a new family of three-dimensional spatio-temporal relevant logics as a hopeful candidate for the fundamental logic, and shows that the logics can satisfy all the requirements for the fundamental logic we need.
