While reading The Autobiography of Charles Darwin, I noticed not only the great things that Darwin accomplished, but his love for science that allowed him to be successful in his work. From Benjamin Franklin’s autobiography, and the steps that he takes in order to attain moral perfection, we can see that he has a driving obsession with the scientific method. However, Franklin never goes as far to say that he outright loves science. Charles Darwin, in his autobiography, states “I love science.” Darwin identifying this emotional attachment to science shows a lot about his character. Charles Darwin does not just want to, or need to, understand science; he finds great pleasure and emotion in science — even in the sciences that he is not as fond of. This passion and emotion allows Darwin to go out and discover new and fascinating things. As a scientists, if you do not have passion and emotion for the work that you are doing, then you most likely do not like what you do. Not only do you not like what you are doing, you probably are not going out and making this scientific discoveries, but if you do go out and make these discoveries, without love for science, you will not perform as well as someone who has this love and passion for science. Benjamin Franklin enjoyed science but his passion for it, I believe, is not as strong as that of Charles Darwin. Darwin needs to do science, and finds great pleasure from it. He even goes on, in his autobiography, to say that as soon as he was done being ill he would jump right back up and start working on his discoveries. This just shows the kind of man Darwin was. His passion and love from science could not be slowed, or stopped, just because of him being ill. He fought through it just so that he may once again do the thing that he loves to do the most — science. It’s this passion and emotion that Darwin displays, that distinguishes the good scientists from the great ones. I believe that Charles Darwin was able to be a great scientist because of the passion and love of science that he has throughout his life.
