The pretended Rights of Man, which have made this havoc, cannot be the rights of the people. For to be a people and to have these rights are incompatible. The one supposes the presence, the other the absence, of a state of civil society.--BURKE, _Appeal from the New to the Old Whigs_. A constitution is the property of a nation and not of those who exercise the Government.--T. PAINE, _Rights of Man_, part ii. In the midst of a maze of events there may sometimes be found one which serves as a clue, revealing hidden paths, connecting ways which seem far apart, and leading to a clear issue. Such was the attempted flight of Louis XVI and Marie Antoinette to the eastern frontier of France at midsummer 1791, which may be termed the central event of the French Revolution, at least in its first phases. The aim of joining the armed bands of _emigres_ and the forces held in readiness by Austria was so obvious as to dispel the myth of "a patriot King" misled for a time by evil counsellors. True, the moderates, from sheer alarm, still sought to save the monarchy, and for a time with surprising success. But bolder men, possessed both of insight and humour, perceived the futility of all such efforts to hold down on the throne the father of his people lest he should again run away. In this perception the young Republican party found its genesis and its inspiration. In truth, the attempted flight of the King was a death-blow to the moderate party, into which the lamented leader, Mirabeau, had sought to infuse some of his masterful energy. Thenceforth, the future belonged either to the Jacobins or to the out and out royalists. These last saw the horizon brighten in the East. Louis XVI being under constraint in Paris, their leaders were the French Princes, the Comte de Provence (afterwards Louis XVIII) and the Comte d'Artois (Charles X). Around them at Coblentz there clustered angry swarms of French nobles, gentlemen, and orthodox priests, whose zeal was reckoned by the earliness of the date at which they had "emigrated." For many months the agents of these _emigres_ had vainly urged the Chanceries of the Continent to a royalist crusade against the French rebels; and it seemed appropriate that Gustavus III of Sweden should be their only convert. Now of a sudden their demands appeared, instinct with statecraft; and courtiers everywhere exclaimed that "the French pest" must be stamped out. In that thought lay in germ a quarter of a century of war.
