This book doesn't do much to detail cultural elements of the three Southeast Asian countries it covers; Thailand, Indonesia, and the Philippines... instead, under the idea that culture is always shifting, the book explores the idealogies of the region.
After years of study, the author has gotten a people that tend to shy away from talking about their true selves to open up to him, and has laid out the basic foundations of the mindset of these peoples, as well as explaining how it has changed during the age of exploration, the industrial revolution, and modern globalization.
He has shyed away from defining the societies by the little rituals and knick knacks, and defined the base for these things, as they shifted and continue to shift over time, and did a relatively decent job of organizing it into a structured text (my only complaint - the chapters never stick to the region they start out talking about, and a lot of the information is badly organized)
