““It must be understood then that there are certain things which, since they are not subject to our power, are matters of speculation, but not of action: such are Mathematics and Physics, and things divine. But there are some things which, since they are subject to our power, are matters of action as well as of speculation, and in them we do not act for the sake of speculation, but contrariwise: for in such things action is the end. Now, since the matter which we have in hand has to do with states, nay, with the very origin and principle of good forms of government, and since all that concerns states is subject to our power, it is manifest that our subject is not in the first place speculation, but action.””
