In a subsequent letter to his son in 1768, Franklin again indulges the same day dream, and again reaches the conclusion that such a union would be the best for the whole, and that, though particular parts might find particular disadvantages in it, they would find greater advantages in the security arising to every part from the increased strength of the whole. But such a union, he concluded, was not likely to take place, while the nature of the existing relation was so little understood on both sides of the water, and sentiments concerning it remained so widely different. Nothing, therefore, remained for Franklin to do except to fall back upon this relation and to make the best of it, to insist that the only constitutional tie between England and the Colonies was the King, and that Parliament had no more right to tax America than to tax Hanover, though the legislative assemblies of the colonies would always be ready in the future as they had been in the past to honor the requisitions for pecuniary aids made upon them by the King, through his Secretary of State; to combat the political and economic dogmas and the national prejudices which stood in the way of the full recognition by England of the fact that her true interest was to be found in the liberal treatment of the Colonies; to warn the Colonies that their connection with England was attended with too many obligations and advantages to be hastily or prematurely forfeited by rash resentments, so long as there was any definite prospect of their appeal to English self-interest and good-feeling not proving in vain; and finally to couple the warning with the suggestion that they should unceasingly keep up the assertion of their just rights, and be prepared, all else failing, to maintain them with an unabated military spirit. It was not to be expected of a man so conservative and constant in nature, and bound to England by so many strong and endearing associations, that he should wage a solitary combat for American rights on English soil before he or any man had reason to know how bitterly the Stamp Act would be returned upon the head of Parliament by America, but never, after the temper of his countrymen in regard to it, was made manifest to him, were his elbows again out of touch with those of his compatriots in America. To their assistance and to the assistance as well of the great body of wise and generous Englishmen, who loved liberty too much at home to begrudge it to Englishmen in America, he brought his every resource, his scientific fame, his social gifts, his personal popularity, his knowledge of the world and the levers by which it is moved, the sane, searching mind, too full of light for bigotry, superstition, or confusion, the pen that enlisted satirical point as readily as grave dissertation in the service of instruction. It cannot be doubted that his exertions should be reckoned among the potent influences that secured the repeal of the Stamp Act.
