A detailed chapter on institutionalism and Islamic Political Economy appears in the author's Studies in Islamic Social Sciences, forthcoming, Macmillan Press Ltd. London & St. Martin's Press, New York. 

The following formalisation shows that in a system of methodological individualism in the small or in the large, it is impossible to infer the existence of any interactive subsystem. In the Islamic socio-scientific order, interactions are endemic and equivalent to the evolutionary knowledge-centered worldview. Systems perpetually evolve in the midst of interactions. When an integration, i.e. social consensus (Ijma) occurs, this must be short-lived, in the sense that new springs of knowledge energe. These then carry the old consensus level to higher ones. In the cognitive level of the knowledge-induced forms, the moral-material tuplets that we talked about earlier, are themselves of higher vintages. An example we took earlier in this regard, is the dynamic basic needs basket of goods, technology and developmental stages.
