摘　　要：许多逻辑教材将4种直言判断的"逻辑方阵(对当关系)"运用到同样是4个种类的模态判断和规范判断身上,从而导致了严重的逻辑混乱与错误。直言判断"逻辑方阵(对当关系)"的成立需要3个条件,其主要根基是对主项和谓项外延关系的穷尽分析,而所谓模态判断与规范判断的"逻辑方阵(对当关系)"却缺乏这些条件,因此是根本不能成立的。把"逻辑方阵(对当关系)"套到规范判断上是更大的错误。Many logic textbooks apply four ＂logical squares＂（opposition relation） of categorical judgment to four kinds of modal judgment and normative judgment,leading to serious logic confusion and mistakes.The establishment of logical square of categorical judgment needs three conditions,the main basis of which is the ultimate analysis of the extension relation of principal term and logic predicate.The so-called ＂logical square＂（opposition relation） of modal judgment and normative judgment is lack of those conditions,therefore it cannot be established.It makes an even greater mistake to apply ＂logical square＂mechanically to normative judgment.

关 键 词：逻辑方阵 对当关系 直言判断 适用范围
