In public speech, as in electricity, there is a positive and a negative force. Either you or your audience are going to possess the positive factor. If you assume it you can almost invariably make it yours. If you assume the negative you are sure to be negative. Assuming a virtue or a vice vitalizes it. Summon all your power of self-direction, and remember that though your audience is infinitely more important than you, the truth is more important than both of you, because it is eternal. If your mind falters in its leadership the sword will drop from your hands.
