semantic considerations in explaining the unity or difference of concepts of attributes of god from the perspective of avicenna and mulla sadra

avicenna argued that the concept of god's attributes are identical, and mulla sadra stresses on the unity of attributes in concept and difference of them in real and rejected the perspective of the avicenna. this article is trying to begin with the two competing views can be explained by on the base of some of the topics in the semantic and then analyzed its foundation, and results. avicenna's theory on the meaning of the words stresses on use. however, for sadra the meanings of words when enacted is more important. according to the descriptive theory of meaning the theory of unity of divine attributes can be meant to correcting our vision about characteristics of the self-existent. with separating primary meaning of the words and their applications with emphasis on alston’s functionalism we could pass from primary meanings of words provides a flexible way to change language and ultimately unite the meanings of god's attributes. in addition, to abandon the extreme views of the deniers and supporters of synonymy and choose the middle path of unity difference (sequence) to maintain the concept of the divine attributes. thus avicenna's view is a corrective theory about the semantics of divine attributes that enhance the knowledge of the divine decree in determining the meaning of words but mulla sadra's theory is descriptive theory that with attention to difference of concepts of attributes stresses on correcting attribution and usefulness of it.
