# General Approach to Nonmonotonic Logics

Witold Lukaszewicz

*Proceedings of the Eighth International Joint Conference on Artificial Intelligence*, pages 352-353.

## Abstract

Nonmonotonic logics are logics in which theorems can be invalidated by new axioms. In this paper we propose a general framework in which a large class of nonmonotonic logics can be specified.
