The article examines the cultivation of revolutionary nationalisms and the construction of postcolonial subjectivities under a foreign regime. The analysis centers on "The Philippine Readers," one of the longest published and most widely adopted reading series for elementary students in grades 1 to 7 in the Philippines from the 1920s to the 1960s. Due to its use and scope, the "Readers" significantly impacted the development of Filipino mind, character, teaching, and learning for generations. The article mobilizes Michel Foucault's notion of care of the self, whereby individuals undergo intensive self-scrutiny through texts that serve as manuals for living. It contends that the "Readers" functioned as a crucial guide that enabled Filipinos to care for themselves in instilling furtive yet subversive forms of nationalism under United States rule. More specifically, two forms of nationalism are discussed, and the concepts of covert and hybrid nationalisms are situated within scholarly discussions regarding colonial complicity and opposition as well as Western and indigenous influences.
