I am inadequet to distill my love for my wife and children to a number. If you can do this for love and justice, please let all on this thread know how this is to be done. I cannot explain love and justice by micrgenetic abberations selected for and expressed outwardly phenotypically. So please, educate me on this matter, as this assignment is above my pay grade. I did used to tell my little children, when I held my arms out as far I could and tell them,as I strained to increase that distance, I would say "I love you more than this". But that was not the analytical application you seek. I will be listening to your lecture very carefully. I don't want to miss this.
My point is that without a rigorous definition of love (or justice or any other such quality that you mention) and a rigorous way to measure such a quality, it would be difficult to do any kind of scientific determination that would make any sense. I was not suggesting that such a quantitative treatment would be possible, but rather suggesting that a scientific theory should not be faulted for failing to account for qualities that are difficult to treat scientifically.
