Philippine Society and Revolution (translated in Filipino as Lipunan at Rebolusyong Pilipino), first published in 1971, is a book written by Filipino Maoist revolutionary and founder of the Communist Party of the Philippines Jose Maria Sison, under his nom de guerre Amado Guerrero. Regarded as one of the CPP's principal references, PSR has also influenced the Filipino mass movement since its first publication. It applied Maoist analysis to contemporary Filipino society, describing its class structure, its basic problems, and the "class logic of the revolutionary solution — which is the people's democratic revolution."
