Personally, I do not believe that our civilization will fall. I think that on the whole we have grown better and not worse. I think that on the whole the future holds more for us than even the great past has held. But, assuredly, the dreams of golden glory in the future will not come true unless, high of heart and strong of hand, by our own mighty deeds we make them come true. We can not afford to develop any one set of qualities, any one set of activities, at the cost of seeing others, equally necessary, atrophied. Neither the military efficiency of the Mongol, the extraordinary business ability of the Phoenician, nor the subtle and polished intellect of the Greek availed to avert destruction.
