Theodore Roosevelt actually said...

Let us above all things beware in using the knife not to handle it so that it will be dangerous to the community even more than to the evil ...

In this life as a rule the job that is easy to do is not very well worth while doing.

Evils have come through our very prosperity, but in warring against the evil let us be exceeding careful not to war against the prosperity.

Let's devote our best thought and best energies to finding some method of getting rid of any and all evils in the body politic.
