But the conflict thus provoked was necessary to the evolution which Providence was preparing. The soul grows strong through hardship; truth conquers by struggling against opposition. It is by resistance, at first instinctive, against restraint that the infant attains self-consciousness. The first settlers who came across the ocean were animated solely by the desire to escape from oppression in their native land; they had as yet no purpose to set up an independent empire. But, as the breath of the forest and the prairie entered into their lungs, and the untrammeled spaciousness of the virgin continent unshackled their minds, they began to resent, though at first timidly, the arrogant pretension to rule them across the waves. Their environment gave them courage, made them hardy and self-dependent, enlightened their intelligence, weaned them from vain traditions, revealed to them the truth that man's birthright is liberty. And gradually, as the reins of tyranny were drawn tighter, these pioneers of the New Day were wrought up to the pitch of throwing off all allegiance, and setting their lives upon the cast. The idea of political freedom is commonplace now; but to conceive it for the first time required a mighty effort, and it could have been accomplished nowhere else than in a vast and untrodden land. The Declaration of Independence, nearly three centuries after Columbus's discovery of America, showed the hitherto blind and sordid world what America was discovered for. Individual men of genius had surmised it many years before; but their hope of forecast had been deemed but an idle vision until in a moment, as it were, the reality was born.
