The origin and the causes of those movements in public opinion which bring about great constitutional and social changes are frequently most difficult to trace, especially by contemporary observers. For a full understanding of such movements, it is necessary to wait for the historian's point of view, and to survey a wider field than is possible whilst the events are occurring, when much of the material for final judgment as to the causes in operation is concealed in an undisclosed future. That there is a movement in progress tending to the nationalization of railways in England is apparent to every thoughtful observer of the times. But whence does this movement come, and what are its principal causes? We are able to identify some of them, less able to weigh the relative importance of each, still less able to foretell the ultimate share which each will have on the future course of development, which will depend on the direction taken by other movements in public opinion which, at the moment, may seem to be entirely independent of all connection with the particular movement we are considering. I will refer to a few of the causes which seem to me to be most prominently at work, but I will not attempt to state them in the order of their importance. I will merely enumerate those which are plainly discernible as existing in some shape or other. The first I will name, though it may not be the most influential, is the existence of a certain amount of dissatisfaction with the present state of railway administration. I suppose that if railway services were as good as possible, charges as cheap as possible, profits as high as possible, and the management as perfect as it is possible for railway management to be, and these conditions were generally admitted to exist, the natural instinct to leave well alone would prevent any proposal for nationalization from obtaining a hearing.
