" When an apple has ripened and falls, why does it fall? Because of its attraction to the earth, because its stalk withers, because it is dried by the sun, because it grows heavier, because the wind shakes it or because the boy standing below wants to eat it? Nothing is the cause All this is only the coincidence of conditions in which all vital organic and elemental events occur. And the Botanist who finds that the Apple Falls because the cellular tissue decays and so forth, is equally right with the Child Who stands under the tree and says the Apple fell because he wanted to eat it and prayed for it. Equally right or wrong is he who says that Napoleon went to Moscow because he wanted to, and perished because Alexander desired his destruction, and he who says that and undermined hill weighing a million tons fell because the last navvy struck it for the last time with his mattock. In historic events the so-called great men are labels giving names to events, and like labels they have but the smallest connection with the event itself "
