RENATO2025-04-01T18:08:24+08:00March 5, 2025|

We had a blast yesterday with St. Theresa's High School Batch '68! You just knew they were from STC as the battalion of Kitakids walked in with vim and verve together with some spouses and younger Theresians. The entirety of Linangan Gallery felt younger in their presence. Still buzzing from the interaction, we were humming "Elenore", one of the top hits of 1968, after the event wrapped up. What a gorgeous discussion, and what a gorgeous day it was. [...]

Transdiscplinary Lecture on Mathematics and Nationalism by Dr. Fidel Nemenzo

RENATO2025-04-01T18:03:04+08:00March 4, 2025|

Maraming salamat Dr. Fidel Nemenzo for leading the discussion on mathematics, history, and the climate crisis. Transdisciplinary teaching - pedagogy across disciplines rather than just many disciplines or specializations - is the way to true learning. The lecture is the latest of a series of collaborative activities between the Constantino Foundation and the Polytechnic University of the Philippines, which is marking its 120th founding anniversary this year.

“We have been so wonderfully blessed in the past week by the presence of tremendously inspiring people, one of them, the one who likes to “shake trees”, is Sir Renato Redentor Constantino who moved the entire plenary to feel, think, and act… people couldn’t help but share and talk about the presentation. I told Sir Red that by the second day of the event, people realized there were ‘deeper commitments than professionalism.’”

"... A Past Revisited sparked a different kind of revolution, one that urged Filipinos to view history through our own eyes and experiences. Thank you very much to our dear friend, ABS-CBN’s Karmina Constantino, a resident of San Juan, for inviting me to be part of this historic occasion."

“Frequented the area in the early ’80s because of Popular Bookstore (small door, beside the gate of Mapua High School), the only one that carried engineering books required for our course. It was still Martial Law… One buys … dangerous reading materials afraid of the Secret Marshals who were then infamous for salvaging (tokhang in the time of tatay digong) petty criminals and activists. Across Mapua High then was a parking lot of mini buses – now the Manila Grand Opera.”

“A Past Revisited was both a revelation and a challenge. It made us see the familiar narratives of Philippine history in new and unsettling ways. It invited us to ask deeper questions—about power, about colonial legacies, about the struggles and aspirations of our people. And it also gave us a sense of responsibility: to carry history forward not just as memory, but as a guide for action and transformation.”

It was a lovely afternoon spent learning about history, poetry, art, climate change, street names, the bicycles in revolution, kickass heroines, and much more!
