First, what is a revolution? Sometimes I'm inclined to believe that many of our people are using this word "revolution" loosely, without taking careful consideration [of] what this word actually means, and what its historic characteristics are. When you study the historic nature of revolutions, the motive of a revolution, the objective of a revolution, and the result of a revolution, and the methods used in a revolution, you may change words. You may devise another program. You may change your goal and you may change your mind.
