And those who oppose all reform will do well to remember that ruin in its worst form is inevitable if our National life brings us nothing whatever but a swollen and badly distributed material prosperity.

Therefore I believe that the destinies of this country should be shaped primarily by moral forces, and by material forces only as they are subordinated to these moral forces.
