Unless truth is absolute, it is not truth. A relative truth is only a useful lie. An approximate truth is only called so politely; it is a lie, because something is either truth or untruth. 'There is no way in between.
There is only one truth. What German Chancellor Adenauer has counted as four, are four aspects of it. He says there are four truths: the simple, the pure, the plain, and the whole truth. The first thing to remember is that the truth is always whole, just as the circle is always whole. You cannot have a half-circle. The moment it is half, it is only an arc, it is not a circle. The very word circle means the whole. If you say it is only a relative truth, then it is not truth because it is dependent, and truth is never dependent on anything.
A loving couple wanted to marry immediately, but the girl's strong-willed and domineering mother adamantly opposed the union.
"I can't help it," said the distraught girl to her boyfriend. "Mother thinks you are effeminate."
Reflecting for a moment, he replied, "You know, compared with her, maybe I am."
This is relative truth, but a relative truth is not the truth. Only the absolute and the whole is the truth -- and it is bound to be plain.
