But apart from this natural process of combination there were other influences at work bringing the colonists into unity. There was the pressure of a common necessity--the necessity of taking care of themselves, of making their own living in a hard, new world. There was the pressure of a common danger--the danger from the fierce and treacherous savages who surrounded them and continually threatened them with pillage and slaughter. There was the pressure of a common discipline--the discipline of building up an organized industry, a civilized community in the wilderness. Yet I doubt whether even these potent forces of compression, of fusion, of metamorphosis, would have made one people of the colonists quite so quickly, quite so thoroughly, if it had not been for certain affinities of spirit, certain ideals and purposes which influenced them all, and which made the blending easier and more complete. Most of the colonists of the seventeenth century, you will observe, were people who in one way or another had suffered for their religious convictions, whether they were Puritans or Catholics, Episcopalians or Presbyterians, Quakers or Anabaptists. The almost invariable effect of suffering for religion is to deepen its power and to intensify the desire for liberty to practise it. It is true that other motives, the love of adventure, the desire to attain prosperity in the affairs of this world, and in some cases the wish to escape from the consequences of misconduct or misfortune in the old country, played a part in the settlement of America. Nothing could be more absurd than the complacent assumption that all the ancestors from whom the "Colonial Dames" or the "Sons of the Revolution" delight to trace their descent were persons of distinguished character and fervent piety. But the most characteristic element of the early emigration was religious, and that not by convention and conformity, but by conscience and conviction. There was less difference among the various colonies in this respect than is generally imagined. The New Englanders, who have written most of the American histories, have been in the way of claiming the lion's share of the religious influence for the Puritans. But while Massachusetts was a religious colony with commercial tendencies, New Amsterdam was a commercial colony with religious principles. The Virginia parson prayed by the book, and the Pennsylvania Quaker made silence the most important part of his ritual, but alike on the banks of the James and on the shores of the Delaware the ultimate significance and value of life were interpreted in terms of religion.
