“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.”

Dr. Chas M. Navarro
Commissioner, National Historical Commission of the Philippines (NHCP)

“Yes, third time [sila/Inang Laya] pumunta at kumanta sa rally sa Dasmarinas town plaza, sa parish church sa our Lady of Perpetual Help sa Dasmariñas Bagong Bayan and sa martsa rali ng mga maralitang lunsod from Dasmariñas to Bacoor na hinarang sumama at di sya [Karina Constantino-David] umalis hanggang kinabukasan.”

“At a low point in my life, I received a note from Letizia Constantino, unsolicited advice that encouraged me to keep writing. I never got to thank her personally for that pat on the back; this column is belated gratitude.”

“Good read. At aliw. Ito ang kahapon na masarap balikan!”

“One of the most towering texts of nationalist historiography — co-authored by Letizia Constantino, whose voice carried the struggle for true independence into classrooms and beyond.”

"... 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."

San Juan City Governor , On his speech at APR 50th anniversary edition launch at NHCP Museo El Deposito

“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.”

Melvin Purzuelo
Iloilo environmentalist, commenting on the foundation’s history article in BusinessMirror,
“Cycling through the fabled history of an opera house, now a hotel,” June 2024.
"Thank you for having us ... We truly enjoyed ourselves. The exhibit was very inspiring, beautifully presented and so insightful. We were all so impressed. Hope we can use some of the material in our Women’s Museum. ❤️"

“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.’”

Floraime Pantaleta
Executive Director, Ateneo Zamboanga-Mindanao Institute
“Thank you very much, Constantino Foundation! It was a lovely afternoon spent learning about history, poetry, art, climate change, street names, the bicycles in revolution, kickass heroines, and much more! Renato Redentor Constantino’s talk and Renato Senior’s book A Past Revisited really got under my skin. Maraming salamat!”
