The opinion of educated people as to the social value of language is fully set forth in the 'Cortigiano.' There were then persons, at the beginning of the sixteenth century, who purposely kept to the antiquated expressions of Dante and the other Tuscan writers of his time, simply because they were old. Our author forbids the use of them altogether in speech, and is unwilling to permit them even in writing, which he considers a form of speech. Upon this follows the admission that the best style of speech is that which most resembles good writing. We can clearly recognize the author's feeling that people who have anything of importance to say must shape their own speech, and that language is something flexible and changing because it is something living. It is allowable to make use of any expression, however ornate, as long as it is used by the people; nor are non-Tuscan words, or even French and Spanish words forbidden, if custom has once applied them to definite purposes. Thus care and intelligence will produce a language, which, if not the pure old Tuscan, is still Italian, rich in flowers and fruit like a well-kept garden. It belongs to the completeness of the 'Cortigiano' that his wit, his polished manners, and his poetry, must be clothed in this perfect dress.
