Speak as educated nature suggests to you, and you will do well, but let it be educated and not raw, rude, uncultivated nature. Demosthenes took unbounded pains with his voice, and Cicero, who was naturally weak, made a long journey into Greece to correct his manner of speaking. With far nobler themes, let us not be less ambitious to excel.
When you understand silence, you understand words; when you understand words, you understand silence. When you think of silence, you think of words. Until you mistakenly utter bad words, you shall never appreciate the real essence of silence that can speak better at the most tempting moment. Until you miss the opportunity when you should have spoken whilst you kept silent, you shall never value the real value and the timing of words. A good orator knows the right time and timing to blend words and silence in oration. A good orator is good because of words and silence.
In a useful conversation... there is a double coincidence of wants. You have to be interested in what I have to say; I have to be interested in what you have to say. This is an important reason why people with conventional interests seem more socially intelligent. Even if they don't check whether their audience cares, it probably does.
True eloquence is irresistible. It charms by its images of beauty, it enforces an argument by its vehement simplicity. Orators whose speeches are "full of sound and fury, signifying nothing," only prevail where truth is not understood, for knowledge and simplicity are the foundation of all true eloquence. Eloquence abounds in beautiful and natural images, sublime but simple conceptions, in passionate but plain words. Burning words appeal to the emotions as well as to the intellect; they stir the soul and touch the heart.
