Put another way,
political inquiry is never objective
and value-free
but supports,
however unintentionally, particular conceptions of society which favour identifiable sectional interests. Cox argued that neo-realism is a version of problem-solving theory which takes the existing international order for granted and asks how it can be made to function more smoothly'.
