Agustin Rivera was born at Lagos (Jalisco) on February 28, 1824. For a time he studied at the famous Colegio de San Nicolas, at Morelia, and, later, at the Seminario in Guadalajara. In 1848 he was licensed to practice law and in the same year took holy orders. He taught for some time at Guadalajara, and was, for nine years, the attorney of the Ecclesiastical Curia. He finally removed to Lagos, the city of his birth, where he still lives, and where his writings have been published. In 1867, he made a journey to Europe, visiting England, France, Italy, and Russia. His writings have been many, varied, and extensive; the complete list of his books and pamphlets, includes ninety-four titles. Among the best known and most widely mentioned are his Compendio de la Historia antigua de Mexico (Compend of the Ancient History of Mexico), Principios criticos sobre el vireinato de la Nueva España (Critical Observations upon the Vice-Royalty of New Spain), and La Filosofía en Nueva España (Philosophy in New Spain). Two pamphlets, Viaje á las Ruinas de Chicomoztoc (Journey to the Ruins of Chicomoztoc) and Viaje á las Ruinas del Fuerte del Sombrero (Journey to the Ruins of the Fort of Sombrero), have been widely read and are often mentioned.
Our author is vigorous and clear in thought and expression. Extremely liberal in his views, much of his writing has been polemic. In argument he is shrewd and incisive; in criticism, candid but unsparing. His Principios criticos is a scathing arraignment of the government of New Spain under the viceroys. His Filosofía is a part of the same discussion. It forms a large octavo volume. It begins with presenting two Latin documents of the eighteenth century, programs of public actos, given at the Seminario and the Colegio de Santo Tomás in Guadalajara. These serve as the basis for a severe criticism of the philosophical thought and teaching in Spain and New Spain during the vice-regal period. Testimonies
