The Requirement of Developing Research Methods in Persian Literature

All the thinkers believe that the life and existence of any scientific field is dependent on research and investigation, because research is a crucial factor in the development and intellectual foundations of human sciences, conducted according to the circumstances, temporal and spatial necessities. Any scientific research requires various research methods that can help the researcher to carry out the research in a rule-governed manner and step-by-step to achieve the desired scientific results with more certainty and more quickly. The writer believes that such a methodical quality has not been presented in Persian Literature so far, because of the three following factors: firstly the type of definition, secondly the area of functions in literature, and thirdly disbelief to the overlapping of interdisciplinary research methods. Therefore, this study is aimed at accomplishing and serving the same very important purposes.
