Interaction of Two Sects in the Scope of Principles of Jurisprudence

he history of methodology of jurisprudence shows that the first book which has been written about principles of jurisprudence in Shiite is “Al-resala Al-usuliya” or “Al-tazkerah be Usule Al-fegh” that is a valuable work of Sheikh Mofid. Of course appearance of principles of jurisprudence in Shiite is longer. In addition to the existence of some methodological discussions in the words of innocent Imams that show they can be the founders of this science, some books of the era of Imams or the time of minor occultation or majo occultation until the time of Sheikh Mofid have propounded some of the methodological issues. So, the claims of new traditionalists that there is nothing in the words of innocents Imams are basically incorrect.
