Another element in the emergence of the modern progressive outlook upon life is immediately consequent upon the first: world-wide discovery, exploration and intercommunication. Great as the practical results have been which trace their source to the adventurers who, from Columbus down, pioneered unknown seas to unknown lands, the psychological effects have been greater still. Who could longer live cooped up in a static world, when the old barriers were so being overpassed and new continents were inviting adventure, settlement, and social experiment hitherto untried? The theological progressiveness of the Pilgrim Fathers, starting out from Leyden for a new world, was not primarily a matter of speculation; it was even more a matter of an adventurous spirit, which, once admitted into life, could not be kept out of religious thought as well. In Edward Winslow's account of Pastor Robinson's last sermon before the little company of pioneers left Leyden, we read that Robinson "took occasion also miserably to bewaile the state and condition of the Reformed Churches, who were come to a period in Religion, and would goe no further than the instruments of their Reformation: As for example, the _Lutherans_ they could not be drawne to goe beyond what _Luther_ saw, for whatever part of God's will he had further imparted and revealed to _Calvin_, they will die rather than embrace it. And so also, saith he, you see the _Calvinists_, they stick where he left them: a misery much to bee lamented; For though they were precious shining lights in their times, yet God hath not revealed his whole will to them: And were they now living, saith hee, they would bee as ready and willing to embrace further light, as that they had received." [8] Static methods of thinking are here evidently going to pieces before the impact of a distinctly unstatic world. They were looking for "more truth and light yet to breake forth out of his holy Word" [9] because they lived in a time when new things had been happening at an exhilarating rate and when pioneering adventure and general travel in a world of open avenues were already beginning to have that liberating effect which has increased with every passing century.
