Every great civilization that has ever arisen is or has been a composite civilization. Isolate an individual, a community, a people, or a race and no matter how favorable may be the circumstances and environment, the advance made will only be so far and no further, the final point of which advance is characterized by rigidity of thought, fixity of forms, and slavish repetition of actions. The greater Chinese Wall of non-intercourse encircling the Mongolian nation for centuries cast the civilization of the Flowery Kingdom into molds of monotony whose stiffness has yielded only to the breaking of Occidental hammers upon Chinese commercial portals. The autocthonous civilization of Peru and Mexico hardly attained the dignity of semi-barbarism. What might the Inca or Aztec have become had the influx of European culture-impulses reached his mind before its plasticity was lost, or had the gifts of acquired experience and knowledge been brought to him by hands guiltless of his scourging and innocent of his blood? On the other hand, let an individual mingle with his fellows; a race or community enters into political or commercial relation with its neighbors, the divine sparks struck off by the attrition of mind with mind kindle the fires which illumine the spiritual in man and sets in motion the machinery of human progress. What student of history fails to recognize the influence of Phoenician letters and Egyptian thought upon Greek civilization; of Greek literature and ideals upon Roman character and development; of Roman genius for organization and talent for legal forms upon modern enlightened nations; of whatever was best in the past upon whatever is best in the life and thought and aspirations of the present. Egypt began to advance when caravans first made their way to her over heated outlying deserts, for these brought to her something more than myrrh and incense, and precious fabrics. Greece developed with phenomenal rapidity as soon as her galleys sprinkled the blue waters of the Mediterranean, for with every incoming freight came a whisper of rudimentary art or culture which she forthwith clothed in beautiful form and language. England was provincial and primitive until her commercial supremacy made her the bearer of civilization to every corner of the globe. She has received more than she has given. Look where we will, we see unmistakably the effects of action and reaction in the intercourse of nations and communities.
