“Every word uttered evokes the idea of its opposite,” said Goethe. This is true because no single statement can summarize the totality of a person, object, idea or event.

For instance, if I say, “President Obama is a great public speaker,” my listener might be thinking, “Yeah, but…” and then come out with, “He says ‘er’ and ‘uhm’ too much in interviews.”

At that point, I am stuck with rephrasing my original assertion, because I was talking about my impression of the President speaking at formal occasions.

I would have done better to say, “The President is a great public speaker on formal occasions, although he ‘ers’ and ‘uhms’ too much in interviews.”

If I’d said that, then I would have been able to talk about the President’s accomplishments as a platform speaker without having to defend my incomplete assertion.

Furthermore, I would have demonstrated that I had thought about the pros and cons of the President’s speaking style, and would therefore have earned more credibility with my listeners.

It pays to say what you have to say, and also say what you’re not saying.
