We have a tendency to stop at the first answer to our questions and never revisit the question again. For some things that is valid but more often we are just being lazy.
Perhaps we need to think that our answers to our questions are just placeholders until we find or are shown a better answer. This attitude leaves us open to hearing different viewpoints and answers.
Few things are absolute; such as we all breathe, feel, and die that we need to allow differing opinions than our own. After all we are still discovering new things daily.
