Do not ask me from where the question came, but there is a relevant context. A consensus can be a middle ground between two or more competing objectives for which optimality is not a requirement. Harmony, on the other hand, is a natural point of contact or balance between two or more states for which optimality is a requirement. If you are looking for harmony you may be disappointed, because unless we can all step back from our opinions and look at the fundamentals all we may achieve is a consensus. A failure of a consensus solution should ultimately lead us closer to harmony, but should we really be relying on failure to guide us?
