"There were a few human beings who gradually, through the process of invention and experiment, built and operated, first, local river and bay, next, along-shore, then off-shore rafts, dugouts, grass broats, and outrigger sailing canoes. Finally, they developed voluminous rib-bellied fishing vessels, and thereby ventured out to sea for progressively longer periods. Developing ever larger and more capable ships, the seafarers eventually were able to remain for months on the high seas. Thus, these venturers came to live normally at sea. This led them inevitably into world-around, swift, fortune - producing enterprise. Thus they became the first world men. The men who were able to establish themselves on the oceans had also to be extraordinarily effective with the sword upon both land and sea. They had also to have great anticipatory vision, great ship designing capability, and original scientific conceptioning, mathematical skill in navigation and exploration techniques for coping in fog, night, and storm with the invisible hazards of rocks, shoals, and currents. The great sea venturers had to be able to command all the people in their dry land realm order to commandeer the... skills necessary to produce their large, complex ships... There were very few of these top power men. But as they went on their sea ventures they gradually found that the waters interconnected all the world’s people and lands... these very few masters of the water world became incalculably rich and powerful."
