Madrid is the centre of the intellectual life of Spain. It contains a number of academies, colleges, schools, and libraries. The Royal Academy was not founded till 1713; but, as Bourgoanne pointed out in 1789, “there are undoubtedly in Spain more learned men who modestly cultivate the sciences; more men of erudition who are thoroughly acquainted with the history and jurisprudence of their country; more distinguished men of letters and a greater number of poets, who have energy and a fertile and brilliant imagination, than is generally imagined.” Science and letters suffered after the period of Quevedo, Cervantes, Calderon, and Garcilaso, and there was a rapid decline in learning until the eighteenth century. Under Charles III. the cultured life of Madrid was revived. Charles was opposed to the clerical restrictions upon knowledge, and the banning of science was not a part of his policy. He withstood the reactionary forces of the country, and, being himself a man of scholarly tastes, he re-awakened the moribund respect for culture. To encourage the production of books, Charles III. freed all printers from military service. He renewed the universities, built new schools, and treated teachers and professors with fairness and respect, declaring that education is the most important of all social affairs. This revival of learning and of literature was unfortunately transient, for under Charles IV. free discussion was almost impossible in Spain; authors were gagged, and the Inquisition was revived. The study of moral philosophy was forbidden in the universities of the country, for Charles declared that he had no use for philosophers. The first large public library in Madrid was the San Isidro, founded by the Jesuits, and containing about 60,000 volumes. The National Library was built in 1712, but the books were removed to another building about thirty years after. There is a library in connection with the Royal Academy of History in the Calle del León, which contains several thousand books and a number of valuable ancient manuscripts. The University has its own collection of books. This institution was founded in 1508 at Alcalá, and brought to Madrid in 1836. There are about 8000 students. The old Court of Castile had many poets and satirists from the days of Juan II. In the thirteenth century, Castilian became the polite speech of the nation, and the earliest ballads were written in this language. These ballads are the basis of much of the history of Spain, and this was the first form of literature in the city of Madrid. Under Alfonso X. of Castile, who was as skilled in letters as in the conduct of the State, the art of poetry reached a higher order than it had hitherto attained in Spain.
