I enjoyed reading the autobiography. It is written in a simple and straightforward manner; the human side of the author emerges from the text clearly. Darwin was a simple man and an eminent scientist; there was nothing complex about him. He loved what he did for science and naturally wanted to be recognised for his contributions. Evolution was in the air in his time but probably not the way he presented it. He was responsible for formulating the concept of 'natural selection' which makes a whole deal of difference in the theory of evolution. As a scientist, he felt vulnerable perhaps like Newton who did not like to get embroiled in controversies and disputes with Robert Hooke and others. Newton refrained from publishing his work for a long period of time in order to avoid scientific disputes which however muddled the priority claim, later on, with Leibniz for the development of 'calculs'. Darwin hated to deal directly with similar situations such as the argument with Butler. Darwin depended on the advice of his family and friends for handling the argument with Butler. Curiously, however, a dispute on priority of developing the concept of natural selection that could have arisen with Wallace did not happen and both of them (Darwin and Wallace) stayed friends through out their lives. According to Reveal et al: "The story of interrelationship between the two men over their professional careers is one of gentlemanly: Darwin, the Country squire, living off inherited wealth and sound investments on a small estate working leisurely in the pursuit of evolution, and Wallace, the committed socialist, saved ultimately from abject poverty by Darwin and his friends who arranged a Crown pension, laboring seemingly forever in other's shadow".
