The second paragraph of the famous lecture (referenced in the preceding post), thus:
What do we understand by politics? The concept is extremely broad and comprises any kind of independent leadership in action. One speaks of the currency policy of the banks, of the discounting policy of the Reichsbank, of the strike policy of a trade union; one may speak of the educational policy of a municipality or a township, of the policy of the president of a voluntary association, and, finally, even of the policy of a prudent wife who seeks to guide her husband. Tonight, our reflections are, of course, not based upon such a broad concept. We wish to understand by politics only the leadership, or the influencing of the leadership, of a political association, hence today, of a state.
