Teaching the principles of jurisprudence in university courses, especially in the field of law, faces its own difficulties. The textbooks of principles of jurisprudence in the field of science are written in Arabic, while many students have serious problems in understanding Arabic texts. The importance of correct education of the principles of jurisprudence is not hidden from experts. Correct reasoning for legal materials and preventing wrong understanding of laws are the most important reasons for including this course in undergraduate and graduate courses. It is very important to compile a textbook in Persian language that can easily convey the most important contents of the principles of jurisprudence to students. Using the experiences of previous textbooks, the book "Principles of Applied Jurisprudence" has tried to show the application of the principles of jurisprudence in law in a practical way. The widespread acceptance of this book by the academic community indicates that the expectations have been fulfilled to a large extent. On the other hand, the good fortune of the lecturers to the book Principles of Applied Jurisprudence and the existence of some defects in it show the necessity of criticizing this book even more. Dealing with topics whose practical aspect is not very clear is one of the important features of this book. Besides that, there are many materials titled "for further study" which are not mandatory. Since this book is introduced as the main source of MA, this section deserved more attention. In this research, the research method is based on the library.
