This document contains three quotes that express the importance of deep reflection to further understanding and progress. Poincare and Lown agree with Einstein that by examining all aspects of what we know and can predict, we can advance our knowledge. If we do not question previous beliefs, we cannot determine what is factual or truly accepted as true. Only by questioning old beliefs can we make informed choices about actions and predict their consequences to help develop future opportunities. Reflection and consideration of potential outcomes are necessary to guide decisions and lead to discovery.
