While Addison was hesitating what profession to follow, the leaders of the political parties were casting about for men of literary power. A new force had appeared in English politics--the force of public opinion; and in their experiments to control and direct this novel force, politicians were eager to secure the aid of men of Letters. The shifting of power to the House of Commons involved a radical readjustment, not only of the mechanism of political action, but of the attitude of public men to the nation. They felt the need of trained and persuasive interpreters and advocates; of the resources of wit, satire, and humor. It was this very practical service which literature was in the way of rendering to political parties, rather than any deep regard for literature itself, which brought about a brief but brilliant alliance between groups of men who have not often worked together to mutual advantage. It must be said, however, that there was among the great Whig and Tory leaders of the time a certain liberality of taste, and a care for those things which give public life dignity and elegance, which were entirely absent from Robert Walpole and the leaders of the two succeeding reigns, when literature and politics were completely divorced, and the government knew little and cared less for the welfare of the arts. Addison came on the stage at the very moment when the government was not only ready but eager to foster such talents as his. He was a Whig of pronounced although modern type, and the Whigs were in power.
