Whilst Popper is correct in saying that you may (seemingly) resolve conflicts if you ignore definition alignment and go with a subjective approach. Just assume you are talking about the same thing and find accord. This is problematic because once instantiated, it will be realised that there was no common centre, and so the next round commences.
In some ways this comports with my language insufficiency postion—these terms are undefinable, so waiting for full agreement will require an infinite amount of time—, but pretending that one can ignore this step is fool’s play.
One approach might be to atomise a concept such as justice, thereby attempting to resolve a portion, but I’ll posit that this atomic approach will yield protons, neutron, electron, and then quarks and subatomic particles and quantum strangeness, so all we’ve managed is to kick the can down the road.
The best this attempt at a pragmatic approach yields is a pregnant pause, but it won’t remain resolved. It’s easy to blame the instability on the dynamism of society—and this does likely exascerbate the issue—, but this issue is inherently unstable at the start. Like an isotope, it’s just ready for any disturbance.
