It is by no means otherwise today. The farmer has to be efficient in a peculiar kind of self-control. He needs to invest labor and foresight in an enterprise that affords to the usual person little of the opportunity for quick returns, the sense of personal achievement, or the satisfaction of the desire for competitive face-to-face association with other men which is offered in the city. Men who cultivate on a very large scale and men who enjoy unusual social insight as to the significance of their occupation are exceptions to the general run of farmers. In these days of accessible transportation we have a rapid and highly successful selection which largely eliminates from the farming class the type that does not naturally possess the power to be satisfied with the slowly acquired property, impersonal success, and non-dramatic activities of farming. This process which eliminates the more restless and commercially ambitious from the country has, of course, been at work for generations. It has tended, therefore, to a uniformity of mental characteristics, but it has by no means succeeded in procuring a homogeneous rural mind. The movement has been somewhat modified by the return of people to the country from the city and by the influence on the country mind of the more restless and adventurous rural people who, for one reason or another, have not migrated. In the far West especially, attention has been given to the rural hostility to, or at least the misunderstanding of, city movements which attempt ambitious social advances. It is safe to assume that this attitude of rural people is widespread and is noticeable far west merely because of a greater frankness. The easterner hides his attitude because he has become conscious that it opens him to criticism. This attitude of rural hostility is rooted in the fundamental differences between the thinking of country and of city people, due largely to the process of social selection. This mental difference gives constant opportunity for social friction. If the individuals who live most happily in the city and in the country are contrasted, there is reason to suppose that the mental opposition expresses nervous differences. In one we have the more rapid, more changeable, and more consuming thinker, while the thought of the other is slower, more persistent, and less wasteful of nervous energy. The work of the average farmer brings him into limited association with his fellows as compared with the city worker. This fact also operates upon him mentally. He has less sense of social variations and less realization of the need of group solidarity. This results in his having less social passion than his city brother, except when he is caught in a periodic outburst of economic discontent expressed in radical agitation, and also in his having a more feeble class-consciousness and a weaker basis for cooperation. This last limitation is one from which the farmer seriously suffers.
