Priority of Human Writing over Speech from Mulla Sadra viewpoint

Mulla Sadra believes that there is no difference between writing and speech in their essence. By separation of God speech from human speech, we come to this conclusion that based on Mulla Sadra’s philosophy of language and his explanation of language process; human writing is prior over his speech. If achieving of Truth is our criterion, there would be two difficulties in regard to human speech and writing: human mistakes in achieving truth; changing concepts into the agreed words in the process of language. Considering that human speech is prior over his writing, causes the listener, for understanding meaning of the speech, to be confined to the time and situation of the speech; whereas, reading the text causes the reader to analyze all possible meanings of the text. Based on Mulla Sadra’s view, there are two principles in the process of language: rationality before speaking/writing, and analyzing any speech or text.
