In his two articles, F. P. A. Demeterio III attempts to classify works in Filipino philosophy using a list of twelve (or sixteen) supposed discourses that prominent philosophers in the Philippines have engaged in and published over the past few years. From this list, he advises current Filipino philosophers to invest their time and effort in contributing to only five of these because of their alleged higher measure of "developmental potential" as opposed to other discourses. In this paper, we raise some fundamental issues with Demeterio's approach. We show that (i) his work's conclusions rest on questionable methodological assumptions that make (ii) the discourses which the work arrived at and the rankings in terms of "developmental potential" superficial and ungrounded. Finally, (iii) instead of fulfilling the main aim of advancing research in Filipino philosophy, the proposed approach may actually lead to its stagnation and demise. We argue that these issues, if left unanswered, make Demeterio's whole approach to Filipino philosophy unsound and may put into question the employment of such an approach.
