Material implication is an extremely important concept of modern logic,but we encountered a lot of problems as we attempted to analyze and explain the hypothetical proposition of natural language with material implication,this situation obstructs the aim of logic norm and people's correct thinking.

实质蕴涵是现代逻辑的一个极其重要的概念，但是用实质蕴涵理论来分析和说明自然语言中的假言命题却出现了许多解释不通的问题。这种状况有悖于逻辑规范和引导人们进行正确思维及表达的宗旨。

The so-called paradox of material implication is not actually that odd since it is caused by some kind of misunderstanding when people require material implication expressions not only the truth properties but contents and meanings as well in conditions.

实质蕴涵与否定、合取、析取、等值等其他逻辑联结词一样，其实质是对自然语言中复句的关联词所进行的合理的逻辑抽象，所谓的"实质蕴涵怪论"其实并不怪，它是人们要求实质蕴涵反映条件联系中除真假联系之外的内容、意义方面的联系，从而作了错误的解读所造成的；作为一种特殊的条件语句，在反事实条件句与实质蕴涵的关系问题上，在反事实条件句与一般性条件句的区分上，还有很多地方需要进一步探索。

Firstly, it studies the definition of implication and its classification, basing on this, deeply analyzes the relations between implication and the connective "if, then" universally used in our ordinary life. Then the article points out that implication is logical abstract to the connective "If, then" used in the natural language. However, because of different understanding and mastering to it, implication may have different classification, it can't be given a right definition. We must master it by all kinds of concrete implications. According to different criterion, implication has different categories. This article mainly discusses its classification from two sides: Ancient Greece and Medieval's and metalogic's.

首先，论文简要地考察了蕴涵概念的界定，指出蕴涵是对自然语言中连接词"如果，则"的逻辑抽象，而对它的意义的不同理解和把握，则可以有不同种类的蕴涵，不能笼而统之地对蕴涵下一定义，只有通过各种具体蕴涵去掌握有关蕴涵的理论；依据不同的分类标准，蕴涵可以有不同的类型，本文主要讨论古希腊及中世纪对蕴涵所作的分类及从记号学这一元逻辑的角度出发对蕴涵作的分类。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
