I would generally agree with "anything wrong involves some kind of imbalance." Yet I think the expression rightly abstains from resolving its ambiguities, since the converse is (unfortunately) false: "everything right requires every kind of balance."
"Everything right requires every kind of balance" would not know a straight line except through double-reasoning. A straight line is the shortest path between two points. Yes, a straight line avoids too much to the right and too much to the left. But the shortest distance between two points is not much concerned by its negation off to the right or its contradiction over to the left.
Likewise, 2 is not 1 + 1 by virtue of balancing 1 and 3; 2 is 1 + 1 without any knowledge of its negation.
I agree that 1 + 1 = 3 is wrong because the left and right sides of the equals sign are not balanced. So why not say "Anything right is a matter of balancing equal components on either side of the equals sign"? Doesn't this justify such a definition of rightness according to balance?
Maybe this is OK as a definition for true communication (i.e. epistemological rightness), since as we know all words are representations of their objects and not the objects themselves: if a word expresses some quality of its object too much this way or that then the word is wrong in that way, which we might call an imbalance. True.
But regarding ontological truths like existence, self, beauty, elegance, simplicity, sophistication, goodwill and fun, it's not that a good beer is a perfect balance between a best beer and a bad beer; or that a beautiful building is a perfect balance between good light and bad light. Ideal qualities in brewing and architecture exist quite apart from the negations of those qualities.
To sum up, I would say that wrongness can be identified as imbalance, and perhaps in every case. But rightness is not defined or constrained by balance; rightness often contains balance, as the balance between malt and hops or between light and shadow; but this may not be expanded arbitrarily to include every balance we can think of: good beer taste is never a balance between the taste of barley malt and the taste of rat poop.
