These intermediate conditions are of interest precisely because the development of existing activities into the foreseen and desired end depends upon them. To be means for the achieving of present tendencies, to be "between" the agent and his end, to be of interest, are different names for the same thing. When material has to be made interesting, it signifies that as presented, it lacks connection with purposes and present power: or that if the connection be there, it is not perceived. To make it interesting by leading one to realize the connection that exists is simply good sense; to make it interesting by extraneous and artificial inducements deserves all the bad names which have been applied to the doctrine of interest in education. So much for the meaning of the term interest. Now for that of discipline. Where an activity takes time, where many means and obstacles lie between its initiation and completion, deliberation and persistence are required. It is obvious that a very large part of the everyday meaning of will is precisely the deliberate or conscious disposition to persist and endure in a planned course of action in spite of difficulties and contrary solicitations. A man of strong will, in the popular usage of the words, is a man who is neither fickle nor half-hearted in achieving chosen ends. His ability is executive; that is, he persistently and energetically strives to execute or carry out his aims. A weak will is unstable as water. Clearly there are two factors in will. One has to do with the foresight of results, the other with the depth of hold the foreseen outcome has upon the person.
