If we are to periodize the intellectual biography of Rolando Gripaldo into his Mindanaoan, Lasallian, and retirement periods, his Lasallian period would be a very significant one because this is the period where he produced the most important works that earned him a niche as one of the important Filipino philosophers. This paper exposed and analyzed the works of Gripaldo in this very significant period of his intellectual biography. This paper was able to identify four clusters of themes that recur in Gripaldo’s Lasallian period writings: 1) his reflective thoughts on Filipino philosophy, 2) his studies of Filipino philosophical luminaries, 3) his critical Filipino philosophy, and 3) his efforts towards revisionist writing. This paper contributes towards the discourse of Filipino philosophy that studies Filipino philosophical luminaries, a discourse in which Gripaldo was a leading advocate. Contributions in this specific discourse can make Filipino philosophy more mainstream and easier to study, especially for beginners and undergraduate students.
