It is said that logic has no loyalty. Any kind of logic can be concocted to be for or against an issue. Remember those debating contests in school? Pick a topic and tell one person to debate for that topic and the other to debate against it. True wisdom is beyond such logic.
There is no shortage of such controversial topics - in fact, it is the easiest way to divide a group. The topic could be something as simple as the humble apple or as complex as off-shore drilling. It is impossible to know everything and by that metric, any opinion is at best a guess. When our own position is a guess, what are the odds of comprehending another person's point of view?
Nature reflects this wisdom. There isn't only one type of apple, there's hundreds of varieties. There isn't even just one type of fruit, or even one category of food. Nature is comfortable with millions of opinions on everything - birds, leaves, stones and seas. And that is the wisdom beyond arguments. It's all already there to see, no arguments can change that.
Once that wisdom dawns, there are no winners or losers anymore, just the universal truth.
