What is a Theory?

"The only truth is the search for truth"

A hierarchy to help explain Theory (each one contains the one below it):

CIS is Interdisciplinary, and consists of many fragmented disciplines (focus on narrow, fragmented ideas within a discipline).  CIS is typical of the social sciences- it is in need of integration of the fragments (see Michel Foucault)

The disciplinary approach is functionalist- where you wear the blinders of a single discipline.  This looses sight of other factors, but sharpens the image within the range of sight of the paradigm of the discipline.

The multidisciplinary approach is a normative approach that involves all aspects in decisions and attempts to unify different disciplines.
