Part I: Discussions of Terms
The purpose of this part is to recognize appearance of terms from a general view, whether by convention or by absoluteness of the speech, to result in universal rules which clarify minor premises of “the Principle of Appearance” - a general principle to be discussed in detail in the third part. Such discussions are concerned with doubted, disputed dispositions of speech, either dispositions of terms such as command and prohibition or those of sentences such as implicatures of sentences (al-mafāhīm) and the like. As for specific terms and their convention as well as appearances, since there can be no general rule in this connection, they are not to be discussed in this science and it is dictionaries and the like that are supposed to deal with such issues.
