Half a century of digging among the ruins of the past had made me painfully familiar with the feet of clay which were buried deeply in the sands of time and which only too often supported the magnificent superstructure of some of the statues erected to our departed gods and half-gods. But, on the other hand, where would we have been—yes, where would we be today—unless occasionally there had been feet of granite, willing and able to carry their owners into the realm of the unknown and find new roads toward progress? The answer was—nowhere at all. We needed those voortrekkers, as our South African cousins used to call them. We needed a few stout hearts to do the pioneering. Without those men and women who trekked ahead of the rest of the crowd and either found new grazing fields or died in the attempt, no one of us would ever have gotten very far. We would have been obliged to stick to the swampy coastal regions, where we had lived and died until then, since the beginning of time, and we would never have known what lay hidden beyond the distant mountain ranges.
