Updated to reflect a few minor revisions of my current thinking.
Zjabs, One of WOTL's resident Libertarian proponents has often mentioned and illustrated good examples of why no law or rule no matter how well intended will always have imperfections if one is willing to be open to considering them.
Of course in a world of absolutes, they must not allowed to exist since only perfection will pass their test of what reality must eventually consist of.
There is a slight or perhaps not so slight problem with that since that concept of perfection is only viable if we use a narrow definition of one person's the desired perfection.
An ancient Taoist illustration approaches reality by way of the sacred Yin-Yang symbol of a black and white disk where the colors are separated on a "S" shaped border.
Black and white seems how the extreme proponents of many ''isms'' on both the Left and Right would prefer for all of us to see reality.
The wise Taoists were considering the philosophy of imperfection when they invented the this ubiquitous symbol.
Since it seems to have survived over the centuries there may be value in examining it a little more in detail.
In the larger black area is a small white dot. In the larger white area a small black one illustrating the imperfection of each area to be absolutely pure in nature.
This same philosophy also has a greater meaning in the totality of the real world we perceive and exist in.
It even has significance in law as exceptions are one of the Law's major problems.
Those exceptions keep the lawyers and courts in business discussing the justification of legal appeals. Exceptions make some rule harder to live with and some easier.
They don't negate the need for a law to remain on the books.
The scales of justice are a universally accepted symbol of law and a legal system.
The discernment of a law's applicability is often a process of weighing rather than a simple black-white determination.
The philosophy of weighing arguments for and against a standard to arrive at a judgement seems too abstract for absolutists.
If something about a law makes it wrong in their eyes they want it scrapped. In the extreme we would soon be left with no laws until human ingenuity began to again find exceptions leaving humanity in a Darwinian dog-eat-dog world of survival of the fittest.
I prefer my world of exceptions to perfection even if it must consist of some unpopular laws.
Eventually things will and do get worked out.
There is an old German saying that has been translated into English that considers the eventual outcome of unpleasant or undesirable imperfections as they either morph into the new major aspect of reality or disappear along with the principle they are being measured against.
The same with imperfect or unjust laws.
Society and time eventually deals with them in the appropriate manner.
The concept of imperfections as an undesirable traits only is valid on a static basis as time puts the pressure of change on all instances of an unbalanced nature, ergo.
