"Saying what we think gives a wider range of conversation than saying what we know"

In this quote, Cullen Hightower is suggesting that expressing our thoughts and viewpoints can result in a more diverse and appealing conversation than merely stating truths and knowledge. By sharing our personal perspectives and beliefs, we open up the possibility for various viewpoints and ideas to be discussed. This can produce a more dynamic and thought-provoking discussion, as opposed to just reciting info that is already understood. Hightower is stressing the significance of individual expression and the worth it brings to interaction. By motivating people to speak their minds, he thinks that we can broaden the scope of discussion and learn from one another in a more significant way.
