Originally published in 2005, the latest edition of "Kapwa: The Self in the Other" includes key updates, such as an expanded introductory chapter. Essentially, this book is the late Dr. Katrin de Guia's seminal work, featuring her groundbreaking research, which profoundly shaped the modern understanding of Sikolohiyang Pilipino (Filipino indigenous psychology). She was also recognized as the wife of Philippine National Artist Kidlat Tahimik. In her fieldwork alongside traditional healers, wisdom-keepers, and indigenous artists, de Guia illuminated kapwa as the definitive essence of Filipino personhood. She defined kapwa as a relational way of being where the self and the other are inextricably linked. This book is the result of her pioneering research into the unique worldviews and lifestyles of Filipino culture-bearer artists. It comprises narrative accounts, critical essays, and other writing in a variety of literary styles combined with theories and findings about Filipino psychology, cognitive science models, and chaos research, from which a profile of Filipino personhood emerges.
