The Truth of any given problem or situation IS usually simple in that there are probably 2 or 3 basic, underlying factors that hold a problem in suspension and un-resolvability. However, the truth is not simplistic, that is its not a simple one sided answer that ignores and/or denies relevant factors or realities.
The only way a single factor can be the solution to a problem is if that factor is a concept of such depth, such breadth and such Wisdom that its various aspects are all solutions themselves, and this is the case with the deepest concept in human thought and experience, Grace-graciousness.
