But it is not sufficient to picture the new farmer. You must explain him. What is it that makes the new farmer? Who is he? What are his tools? In the first place, you cannot explain the new farmer unless you know the old farmer. You cannot have the new farmer unless you also have the mossback. The new farmer is a comparative person, as it were. You have to define him in terms of the mossback. The contrast is not between the old farmer and the new, for that is merely a question of relative conditions in different epochs of time. The contrast is between the new farmer and the mossback, for that is a question of men and of their relative efficiency as members of the industrial order. Then, of course, you must observe the individual traits that characterize the new farmer, such as keenness, business instinct, readiness to adopt new methods, and, in fact, all the qualities that make a man a success today in any calling. For the new farmer, in respect to his personal qualities, is not a sport, a phenomenon. He does not stand out as a distinct and peculiar specimen. He is a successful American citizen who grows corn instead of making steel rails. But you have not yet explained the new farmer. These personal traits do not explain him. It may be possible to explain an individual and his success by calling attention to his characteristics, and yet you cannot completely analyze him and his career unless you understand the conditions under which he works--the industrial and social environment. Much less can you explain a class of people by describing their personal characteristics. You must reach out into the great current of life that is about them, and discern the direction and power of that current. Now, the conditions that tend to make the new farmer possible may be grouped in an old-fashioned way under two heads. In the old scientific phrases the two forces that make the new farmer are the "struggle for life" and "environment," or, to use other words, competition and opportunity.
