 Friar Alonso de la Veracruz (1507–1584) was the first philosopher of New Spain. A student of Vitoria, he was one of the first to teach Scholastic philosophy in the New World and was the first published philosopher of New Spain. He wrote several commentaries on Aristotle, such as Recognitio summularum (1554a), Dialectica resolutio (1554b), and Physica speculatio (1557), which were used as textbooks. Like Vitoria, Alonso also questioned the justification of the Conquest, but he was even more sympathetic toward the indigenous population. Alonso argued that the natives did not lose their right to their lands because they were pagans, and he claimed that the Spanish Crown had stolen them from their lawful owners. He also sustained that sovereignty ultimately belongs to the people, not the king.
