The Lost Vision gives an account of the Philippine left from 1986-2010, covering the events which have affected the movement in recent decades, such as the demise of the Soviet Union and the other European socialist regimes, and the splits in the CPP in the early 1990s which have led to a proliferation of both organizations and orientations. This also examines the period in the late 1980s when cadres of the CPP, PKP, and others worked together at mass level in a number of progressive and anti-imperialist coalitions before disunity once again prevailed.
The author argues that the Philippine left parties appear to have lost sight (hence the title) of the intermediate aim they once shared: the economic development of the Philippines based on nationalist industrialization, free of the shackles of foreign domination. Only be resuscitating this vision and working to make it a reality, Fuller believes, will disunity be overcome, an alternative to armed struggle developed, and the country rescued from the poverty and underdevelopment which have plagued it for decades.
