Sepúlveda on Natural Law and Just War

Key Claims about Ruling and Inferiority

• The Spanish have a perfect right to rule these barbarians of the New World and adjacent islands.

• These barbarians are described as inferior to the Spanish in prudence, skill, virtues, and humanity.

• The degree of difference is framed with extreme comparisons:

  • "as inferior to the Spanish as children to adults, or women to men"

  • there exists between "savage and cruel races" and the "most merciful" among the Spaniards

  • and even the contrast "between apes and men"

• War against these barbarians is justified not only on the basis of paganism but even more so because of their:

  • abominable recklessness

  • unusual sacrifice of human victims

  • extreme harm that they inflicted on innocent persons

  • horrible banquets of human flesh

  • impious cult of their idols

• The speaker asserts that there is a natural order among humans: some are by nature masters and others by nature slaves.

  • Those who surpass the rest in prudence and intelligence (even if not the physically strongest) are by nature the masters.

  • Those who are dim-witted and mentally lazy, though physically capable, are by nature slaves.

• It is presented as just and useful that the master/slave arrangement exists, and it is even sanctioned by divine law, citing:

  • Book of Proverbs: "He who is stupid will serve the wise man."

• The Indians, in contrast, are depicted as lacking civil life and peaceful customs.

  • They are portrayed as possessing neither science nor an alphabet.

  • They do not preserve monuments of their history, except for some obscure and vague reminiscences depicted in certain paintings.

  • They have no written laws, but instead have barbarous institutions and customs.

• The natural qualities of judgment, talent, magnanimity, temperance, humanity, and religion are attributed to the Spanish (the colonizers) rather than to the Indians.

Justification for War and Civilizing Mission

• The war to subjugate and civilize the Indians is framed as just according to natural law.

• The Spaniards’ purported virtues and practical wisdom are presented as the basis for destroying barbarism and educating these inferior peoples to a more humane and virtuous life.

• If the Indians reject Spanish rule, the rule can be imposed upon them by force of arms.

• The overall logic ties natural law, divine sanction, and civilizational progress into a single justification for conquest.

The Natural Law Framework and Its Implications

• Core claim: there is a natural hierarchy among humans, with some destined to rule and others to serve.

• The hierarchy is justified by reason (prudence, intelligence) and reinforced by divine authority (Proverbs).

• The framework provides a ready-made justification for coercive conquest and the suppression of Indigenous autonomy.

• The language emphasizes utility and order: ruling elites can destroy barbarism and lead inferior peoples to virtue.

Descriptions of Indigenous Nations and Their “Civilizational” Deficits

• Indians are described as lacking:

  • science and alphabet

  • written laws

  • monuments of history

• Indians are said to be characterized by barbarous institutions and customs, with no peaceful or civil life.

• The portrayal relies on sweeping generalizations and essentialist assumptions about culture, intellect, and morality.

The Spaniards as the Bearers of Civilizational Progress

• The Spaniards are depicted as possessing the following natural qualities:

  • judgment, talent, magnanimity, temperance, humanity, religion

• The argument frames Spaniards as uniquely capable of educating others toward humane life, using their superior nature as justification for intervention.

Rhetorical Devices and Framing Techniques

• Extreme differentiation: master/slave by nature; civilized/barbarian; humane/inhumane.

• Metaphors and analogies:

  • "as inferior to the Spanish as children to adults, or women to men"

  • "apes and men" to emphasize supposed natural differences.

• Appeals to divine authority: citations from Proverbs to legitimize domination.

• Binary framing: civilization is achieved or imposed by force if necessary.

Ethical, Philosophical, and Practical Implications

• Ethical issues:

  • Dehumanization and instrumentalization of Indigenous peoples.

  • Endorsement of slavery and coercive rule based on perceived natural differences.

  • Use of religious justification to sanction violence and conquest.

• Philosophical issues:

  • Natural law as a justification for hierarchical social orders.

  • The problem of essentialism: attributing complex cultures to a single, fixed nature.

• Practical implications:

  • Support for coercive expansion and settlement policies.

  • Justification for destruction of indigenous political and legal frameworks.

  • Potential erasure of indigenous cultures under a claim of civilizing mission.

Historical Context and Relevance

• This passage reflects the intellectual backdrop of the Valladolid Controversy, where debates over the rights and treatment of Indigenous peoples were framed as clashes between competing theories of natural law, humanity, and empire.

• The opposing view, associated with Bartolomé de Las Casas, challenged natural law justifications for conquest and argued for the inherent rights and dignity of Indigenous peoples; this excerpt represents the opposing stance.

Key Quotes to Remember

• "The Spanish have a perfect right to rule these barbarians…"

• "as inferior to the Spanish as children to adults, or women to men"

• "There exists between the two as great a difference as between savage and cruel races and the most merciful…"

• "He who is stupid will serve the wise man." (Book of Proverbs)

• "Such a war will be just according to natural law…"

• "Thanks to their virtues and the practical wisdom of their laws, the latter can destroy barbarism and educate these [inferior] people to a more humane and virtuous life."

• "If the latter reject such rule, it can be imposed upon them by force of arms."

• "They possess neither science nor even an alphabet, nor do they preserve any monuments of their history… nor do they have written laws, but barbarous institutions and customs."

Suggested connections for study

• Compare with Las Casas’ arguments for the inherent dignity and rights of Indigenous peoples.

• Analyze how natural law is used to justify political power and social hierarchy.

• Explore how religious texts are invoked to legitimize political and military actions.

• Consider the role of ethnocentrism and essentialism in colonial discourse.

• Reflect on how this historical debate informs modern discussions of human rights, cultural preservation, and the ethics of empire.

Quick recap

• Central claim: Spaniards have a natural and divine right to rule and civilize Indigenous peoples.

• Key mechanism: a natural hierarchy (masters by nature, slaves by nature) justified by prudence/intelligence and biblical sanction.

• Indigenous deficits: lack of science, alphabet, laws, and symbolic monuments; framed as barbarous.

• Civilizing project: education of inferiors through virtue, or coercive enforcement by arms if necessary.

• Ethical tension: deep dehumanization and legitimization of violence under the banner of natural law and religion.
