Methods involve the application of specific ordering principles in order to construct empirical domains. These principles are not theory neutral but are based on definite ontological presuppositions. Where the presuppositions of a method conflict with those of a particular theory, that theory cannot be appropriately tested by an application of this method. However, it is an important function of methods, not only to "test' theories, but also to demonstrate them in action. Where the theories in question refer to the foundations of human social action appropriate methods are those which constitute empirical domains that reflect the structure of such action.
