law of excluded middle

My Ideas about Field limitation of the Law of Non-contradiction and the Law of Excluded Middle and Its Expression of Basic Contents

关于不矛盾律和排中律适用范围界定及基本内容表述之我见

互联网摘选

At present textbooks of logic in different editions all give indistinct field limitation for the law of non-contradiction and the law of excluded middle and meanwhile expression of basic contents of the two laws is not clear and simple.

目前，多种版本的逻辑学教材，均对不矛盾律和排中律适用范围的界定模糊不清，对这两条基本规律基本内容的表述，也不明确、不全面。
