"I believe that a political party, to be a useful agency in this country for the promotion of the happiness of our people, must be a progressive, dynamic force; it must have a doctrine, a program, legislative and otherwise, that is; moderate in its approach, avoiding extremes of right and left. As I have told you before, I think it must be liberal when it is talking about the relationship between the Government and the individual; conservative when talking about the national economy and the individual's pocketbook. That is my rough conception of progressivism, and I believe the Republican Party must be that or it won't be any force long in American life. I just don't believe that; Americans, 163 [million] intelligent Americans, are going to be satisfied either with the action or with such a distinct trend toward centralization and paternalism in our Government that it becomes difficult to detect it from a socialistic form. So I don't care when this occurs; I am not talking about conventions, I am not thinking of such things. I am thinking merely of where does a great party like the Republican Party, what direction does it have to take, if it is going to be a useful agency for America."
