In religion we have a saying, “Who is more foolish; a child afraid of the dark or a man afraid of the light?”  This is an interesting statement.  It goes to the heart of the matter of what do you really see, and in so doing, what do you comprehend?  What is filtered out and what is of interest to a person?  What is retained and what is useful?  Although the questions seem endless; the core problem is observation first and then all of the other questions follow.  In other words, you must first observe – see it, hear it, taste it, feel it, and smell it – before you can evaluate it with a bombardment of other questions.
