The lodestar of his hopes is liberty, his main end the establishment of "a free commonwealth." He knows as well as Montesquieu that democracy in its pristine dignity can be erected only on a wide foundation of public virtue. "To govern well," he declares in the treatise _Of Reformation in England_, "is to train up a nation in true wisdom and virtue, and that which springs from thence, magnanimity (take heed of that), and that which is our beginning, regeneration, and happiest end, likeness to God, which in one word we call godliness;... other things follow as the shadow does the substance." In the same pamphlet this envious hater of greatness remarks that "to govern a nation piously and justly, which only is to say happily, is for a spirit of the greatest size, and divinest mettle." And men worthy of this description had, as it seemed to him, arisen in his own time. His praise of Cromwell and the leaders associated with him is almost extravagant in its enthusiasm. "While you, O Cromwell, are left among us, he hardly shows a proper confidence in the Supreme, who distrusts the security of England, when he sees that you are in so special a manner the favoured object of the Divine regard." His mind is full of the achievements of Cyrus, Epaminondas, and Scipio; he denies to the Protector no honour that may be drawn from these high comparisons. And then, as in _Lycidas_, so also in _The Second Defence of the People of England_, Milton concludes his celebration of another by a return to himself and his pride in a duty fulfilled. Opportunity, he declares, is offered for great achievements; if it be not seized, posterity will judge "that men only were wanting for the execution; while they were not wanting who could rightly counsel, exhort, inspire, and bind an unfading wreath of praise round the brows of the illustrious actors in so glorious a scene."
