This research notes try to build a question whether a conceptual development of public good can be an useful reference to understanding Wilson`s rather difficult comment on the relationship between the constitutional and the administrative realms demarcated by himself. In order to do this, the analytic notes briefly describe: (1) Wilson`s particular position on his own plan for dichotomy of politics and administration in his "The Study" is conflational, an epistemic imperative: (2) Samuelson of 1954, Tiebout of 1956, and Ostrom, Tiebout and Warren of 1961 undertake together epistemically conflational tasks to solve the problem of the same kind, that is, how to conceive public good: (3) If the initial question is to be positively answered through adequate analyses, proper implications are derived to assess referential usefulness of conceptualization process of public good. Then, we may proceed further to the next question, whether this particular referential usefulness can help us think that both conflations conceived by (1) and (2) are dealing with the same problem in actuality. Understanding Wilson`s distinction between constitution and administration with a higher level of relevance is the larger purpose of the research that this note prepares for only a necessary part of.
