This chapter introduces the purpose of our book—to encourage researchers to study Filipino texts (both spoken and written) and to explore them in a way that clarifies their function in Philippine society. With this goal in mind, we introduce a number of discourse analysis tools and show how to apply them to a range of Filipino texts—including a children’s picture book story, some mental health advice about coping with COVID-19, President Duterte’s speech about the Philippine government’s initial response to the COVID-19 pandemic, a comment piece from a student newspaper about problems with online learning modules produced by the Department of Education and a reflective text about growing up in Davao amidst conflicts with Indigenous people. In support of these goals, we introduce our Systemic Functional Linguistic (FL) perspective and the use we make of its theory and description to inform our twin Critical Discourse Analysis (CDA) and Positive Discourse Analysis (PDA) perspectives.
