The paper is primarily concerned with philosophical logic. A good paper to write in 1939. The laws are equivalent in any logic containing classical logic. He points out the need for developing alternate formalisms in which only one of the laws is to be accepted and that dialectical versions too will need the feature. He actually claims that dialectical logics must be non-classical strictly. I will not agree on that. For example logics about transition of objects from one state to another like linear logics can be interpreted as dialectical ones. A. Mani Member, Cal. Math. Soc A. Mani Member, Cal. Math.
