In the less than four years since the publication of his best-selling, The Filipinos in the Philippines, Renato Constantino has had a notably productive writing career. His first book appeared in 1950. Due no doubt to the hostile atmosphere of the 50's the essays he wrote during this period were not compiled in book form until 1967. Since then, he has published best-selling historical work, The Making of a Filipino, a landmark in Philippine historiography and more so in partisan scholarship. Professor Constantino's writings have met with tremendous success. It is clear that he has built up a large and loyal audience through the years. At the same time, the social ferment itself has created new readers who can now appreciate his ideas.
