In the same way as with the prosody and vocabulary, these changes were effected by degrees. Great confusion prevailed in the thirteenth century; the authors of the "Brut" and the "Ancren Riwle" have visibly no fixed ideas on the use of inflections, or on the distinctions of the genders. Only under Edward III. and Richard II. were the main principles established upon which English grammar rests. As happened also for the vocabulary, in certain exceptional cases the French and the Saxon uses have been both preserved. The possessive case, for instance, can be expressed either by means of a proposition, in French fashion: "The works of Shakespeare," or by means of the ancient genitive: "Shakespeare's works." Thus was formed the new language out of a combination of the two others. In our time, moved by a patriotic but rather preposterous feeling, some have tried to react against the consequences of the Conquest, and undo the work of eight centuries. They have endeavoured to exclude from their writings words of Franco-Latin origin, in order to use only those derived from the Anglo-Saxon spring. A vain undertaking: the progress of a ship cannot be stopped by putting one's shoulder to the bulkheads; a singular misapprehension of history besides. The English people is the offspring of two nations; it has a father and a mother, whose union has been fruitful if stormy; and the parent disowned by some to-day, under cover of filial tenderness, is perhaps not the one who devoted the least care in forming and instructing the common posterity of both. II. The race and the language are transformed; the nation also, considered as a political body, undergoes change. Until the fourteenth century, the centre of thought, of desire, and of ambition was, according to the vocation of each, Rome, Paris, or that movable, ever-shifting centre, the Court of the king. Light, strength, and advancement in the world all proceeded from these various centres. In the fourteenth century, what took place for the race and language takes place also for the nation. It coalesces and condenses; it becomes conscious of its own limits; it discerns and maintains them. The action of Rome is circumscribed; appeals to the pontifical Court are prohibited,[406] and, though they still continue to be made, the oft-expressed wish of the nation is that the king should be judge, not the pope; it is the beginning of the religious supremacy of the English sovereigns. Oxford has grown; it is no longer indispensable to go to Paris in order to learn. Limits are established: the wars with France are royal and not national ones. Edward III., having assumed the title of king of France, his subjects compel him to declare that their allegiance is only owed to him as king of England, and not as king of France.[407] No longer is the nation Anglo-French, Norman, Angevin, or Gascon; it is English; the nebula condenses into a star.
