This does not mean that we must turn back the clock of scientific progress. No one can overlook the wonders that science has wrought for our lives. The automobile will not abdicate in favor of the horse and buggy, or the train in favor of the stagecoach, or the tractor in favor of the hand plow, or the scientific method in favor of ignorance and superstition. But our moral and spiritual "lag" must be redeemed. When scientific power outruns moral power, we end up with guided missiles and misguided men. When we foolishly minimize the internal of our lives and maximize the external, we sign the warrant for our own day of doom.
