José Rizal opens his inquiry by examining the historical burden placed upon the Philippines after Spanish colonization, noting how centuries of foreign administration drained the population, suppressed native traditions, and systematically impoverished local culture. By drawing a parallel between the past and the present, the author demonstrates that while material forces such as military presence and administrative organization have seemingly increased, invisible ethical forces have shifted entirely. The sensitive nature of the Malayan population, once kept docile through paternalistic protection and religious devotion, has been deeply wounded by systemic insults, published slanders, and the denial of basic human rights by colonial authorities.
The author then poses the central question of whether the Philippine Islands will continue as a Spanish colony, become an autonomous province, or separate entirely to live independently or ally with neighboring powers. He systematically evaluates the traditional methods used by governing powers to check national progress, including the brutalization of the masses, economic impoverishment, physical extermination, and the deliberate fostering of provincial feuds. Through careful historical reasoning, he proves that none of these methods can succeed permanently because the population has grown too resilient, education is spreading despite strict censorship, and a common misfortune has united all inhabitants across regional divides.
To prevent a violent and catastrophic rupture, Rizal argues that fundamental political transformations must take place from above rather than through chaotic uprisings from below. He identifies two indispensable reforms required to relieve mounting social pressure: the restoration of a free press to ensure reliable communication between the distant government and the governed, and parliamentary representation through Filipino delegates in the Spanish Cortes. Without these outlets for legitimate grievances, the accumulation of public discontent will inevitably lead to a bloody collision, rendering peaceful coexistence impossible.
Looking toward the ultimate outcome should reforms continue to be denied, the text explores the laws of history regarding foreign domination over distinct races. The author reasons that no lasting empire can maintain control over a population of different usages, ideals, and divergent interests once national self-consciousness has awakened. If Spain persists in treating the islands merely as a source of exploitation rather than a community deserving of liberty, the resulting conflict will force the colony to fight for and secure its absolute independence.
In the concluding analysis, Rizal evaluates the geopolitical position of an independent Philippine nation among neighboring global powers. He anticipates that major empires such as England, Germany, France, and Japan will have neither the motive nor the strategic desire to conquer a newly liberated and fiercely defended archipelago, leaving the nation free to organize a stable federal republic. The text serves as both a profound warning to colonizers and an inspiring manifesto for self-determination.
