Luck, or Cunning, as the Main Means of Organic Modification

In this book, the author, Samuel Butler, presents a simplified view of evolutionary theory as a contrast between the idea of intelligent design and the concept of random variation through natural selection. He portrays Darwin, Spencer and Romanes as advocates for luck and Erasmus Darwin, Buffon and himself as proponents of cunning as they believed in the existence of design and purpose in the universe.
