People say the word “justice” and unconsciously conflate multiple concepts that do not necessarily belong together. I’ll list a few.
The most common concept, in every sense of the word, is ensuring that whoever has been harmed by another is given the satisfaction of revenge. Sadistic pleasure is compensated with sadistic pleasure. An eye for an eye, a tooth for a tooth, dignity for dignity. Everyone gets the same chance to enjoy inflicting suffering on others, to humiliate others, to coerce others — and nobody gets an unfairly large portion in the delight of debasing, controlling and harming others.
A second concept of justice is upholding of law. When the law is inexorably enforced, it reinforces to everyone that the law is a reality, that all must follow it, and that all can count on the fact that it will be followed by others.
A third concept of justice is pluralistic. This justice understands that every subject acts by its own logic — even when it tries to live according to the law. The third justice tries to “do justice” to this logic and to understand why another person thinks, values and acts in the way they do — to get inside their judgment to understand how and why this judgment might deviate from the public judgment.
When we say justice, it is helpful to know 1) which justice or justices we, ourselves, are pursuing, and 2) what justice means for the others involved in the adjudication.
This thought is not mine. I am paraphrasing.
