 On the whole, the political vision outlined above appears to be founded on doctrinal elements of Ismâ‘îli nature. The division between the “elect” and the “masses” destines the former only for investigation of the curriculum studiorum at the basis of the “philosophy of salvation”. A rigid hierarchy of universe links each level of existence, physical and spiritual, to that which precedes and that which follows it where the beings that belong to the various levels cannot go beyond them. (It should be noted that this may question the idea of “evolution” in the Ikhwân that some scholars have ascribed to them; cf. e.g. Vernet Ginés 1990, 190; Marquet 1992). The didactic aims of the ruler mirror the aspect of Ismâ‘îli propaganda known as ta‘lîm (lit.: “teaching”).
