I see truth and lies forming a Yin and Yang pair; there is an element of lie at the heart of the truth - an element of truth at the heart of lies. An example will illustrate what I mean:
If I were to say "I am 50 years old" that would be a true statement; I was born March 30, 1948 - I have had my 50th birthday - as I write this I have not yet had my 51st birthday. However, my statement has in it an element of untruth; I am not exactly 50 years old - in fact it is impossible to say exactly how old I am as this is being written. The process of writing this article is spread over time - as was my birth, and the quantum nature of reality makes an infinitely accurate determination of anything undoable as far as we know.
If I were to say "I am 49 years old" that would be a lie; I have already had my 50th birthday. However there is an element of truth in that lie; I have had my 49th birthday so I am at least 49 years old. If I am an evil person who is trying to keep people from understanding the truth and who was trying to get away with lying I would point out the inaccuracies in the truthful statement and try to confuse people as to which of the statements was true.
Despite these elements of the opposite that exist in each if I say "I am 50 years old" I am telling the truth - I am trying to deliver useful information. If I say "I am 49 years old" I am a liar; I am deliberately trying to give people false information and mislead them.
What makes life confusing are three things about Yin and Yang: the first is what I have just discussed - the element of truth at the heart of a lie, the element of lie at the heart of truth. The second is that Yin and Yang is sometimes a three dimensional structure; it is not always a flat structure. Sometimes most of the truth of something can lie in the small Yin part rather than the large Yang part. This is possible if the small Yin truth resembles a mountain which extends so far that the surface area of the 'mountain' exceeds that of the flat Yang section.
The third factor which makes life confusing was pointed out to me by my good friend Joe Thomas (1991 USAKF Texas State heavyweight Karate champion): Yin and Yang is often a dynamic spinning thing; if you attach a Yin and Yang symbol to a drill motor and spin it it will look gray rather than black and white. To see its underlying nature it is necessary to stop the spinning and examine the static nature - which is what I am attempting to do in this article.
