Fame can turn ideas into weapons. Once a person's reputation becomes tied to being right, defending an argument can become more important than discovering whether the argument is actually true. More than a century ago, Charles Darwin reflected on precisely this tension: the difference between pursuing knowledge and pursuing recognition.
The famous naturalist spent much of his life observing, collecting evidence and gradually constructing an explanation for one of biology's biggest questions, how living species change over generations. But Darwin was also acutely aware of the human emotions surrounding intellectual achievement: ambition, reputation, criticism and the desire to be admired.
