The notion of justice involves the notion of fairness, due rewards/punishment, righting a wrong, restoring a good, etc. It involves a comparision to a standard, eg of acts to a moral code. But why one measure instead of another? Why this moral code or that moral code? And why measure acts at all, ie what is it that should be truly measured for true justice? What is it in our innermost being that compels us to seek or to fear justice?
If we proceed from the notion that good and evil is in a person itself, in his heart, then true justice should weigh the heart of a person, instead of his acts, which are merely the discernible manifestations of his heart. But then against what? A notional, fictitious “pure” heart? How do we measure a person in his being?
Also is it inherently fair in the use of an external, “objective” measure? For example, are equal opportunities truly equal? For only if all have the same capacity and ability to exploit an opportunity to the same degree are equal opportunities equal.
Jesus have said, “For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.” [Matt 7:2]
Now does that - an inter-subjective measure - not appeal to our spirits as a fairer system of justice than a merely objective external measure?
Let me posit the following: that the true measure of justice is our own being: that whom we ought to be. In other words I define true justice as, Ontological Congruence: that which is due to who you are.
The restoration of the departure from who you are truly to be is what I seek for in justice. Goodness or fairness is the degree of match to that ideal being of yourself. And true justice is the attainment of the perfect and complete match.
And who I am to be is my “name known only to me” [Rev 2:17] that God have reserved for me in heaven. And thus only God is the True and Righteous Judge.
However even if Justice is indeed what I posited it to be, there is still the issue of practical justice on earth, which will by necessity and nature be something imperfect. The objective and intent of earthly justice is not to do what God will do, but merely to remind and make people know that there is something call justice, and to deliver a foretaste of what it could be.
