To be sure, an adequate understanding of any purposely employed method includes an understanding of what the one using the method sets up as the thing to be actualized by its means. The goal of Husserlian phenomenological activity is always knowledge, but the initial conception of knowledge - like the initial method and the theory of method undergoes a change, because of cognitional results actually attained. There is.therefore, an analogous reason for not attempting to state the specifically Husserlian phenomenological ideal of knowledge at the beginning of the present essay.
