"Attention is riveted on what is tangible, useful, instantly available; the stimulus for deeper thought and reflection may be lacking. Yet human beings have a vital need for time and inner quiet to ponder and examine life and its mysteries... Understanding and wisdom are the fruit of a contemplative eye upon the world, and do not come from a mere accumulation of facts, no matter how interesting."

The gravest error a thinking person can make is to believe that one particular version of history is absolute fact. History is recorded by a series of observers, none of whom is impartial. The facts are distorted by sheer passage of time and thousands of years of humanity's dark ages, deliberate misrepresentations by religious sects, and the inevitable corruption that comes from an accumulation of careless mistakes. The wise person, then, views history as a set of lessons to be learned, choices and ramifications to be considered and discussed, and mistakes that should never again be made.
