The present research evaluates the claim of "experientiality of revelation" by Mr. Soroush in the book " Basti Tajribiyi Nabavi" from a methodological point of view, using a descriptive, critical and analytical method and based on library findings. Among the axes of criticism and review of a theory is the discovery of the method of design and proof of the theory and its comparison with the scientific method appropriate to the origin of the research problem. Investigations show that Soroush did not use the appropriate scientific method to prove the "experimentality of revelation". Argument in this regard should be a rational finding or a narrative statement and it should be derived from the source of internal or external evidence, but he, by using pubilikly accepted or quasi-accepted, used polemic and address method with the aim of persuading the audience and in this direction, has used fallacies such as "false interpretation", "exaggeration", "blocking the path of reasoning", "irrelevant reason".   Keywords: Revelation, Prophetic Experience, Abdol Karim Soroush, Book Basti Tajribiyi Nabavi, Methodology.
