“In one sense philosophy does nothing. It merely satisfies the entirely impractical craving to probe and adjust ideas which have been found adequate each in its special sphere of use. In the same way the ocean tides do nothing. Twice daily they beat upon the cliffs of continents and then retire. But have patience and look deeper; and you find that in the end whole continents of thought have been submerged by philosophic tides, and have been rebuilt in the depths awaiting emergence. The fate of humanity depends upon the ultimate continental faith by which it shapes its action, and this faith is in the end shaped by philosophy.” 

—Alfred North Whitehead
