The role of outstanding scientists in influencing younger associates is repeatedly emphasized in the interviews with laureates. Almost invariably they lay great emphasis on the importance of problem-finding, not only problem-solving. They uniformly express the strong conviction that what matters most in their work is a developing sense of taste, of judgment, in acting setting upon problems that are of fundamental importance. And, typically, they report that they acquired this sense for the significant problem during their years of training in evocative environments. Reflecting on his years as a novice in the laboratory of a chemist of the first rank, one laureate reports that he "led me to look for important things, whenever possible, rather than work on endless detail or to work just to improve accuracy rather than making a basic new contribution."

Max Weber was right in subscribing to the view that one need not be Caesar in order to understand Caesar. But there is a temptation for us theoretical sociologists to act sometimes as though it is not necessary even to study Caesar in order to understand him. Yet we know that the interplay of theory and research makes both for understanding of the specific case and expansion of the general rule.
