You know, I like you and you strike me as a fairly genuine inquirer, but you have this tendency to slip into sophism when it suits you, and that really impedes discourse. Let me take two swipes at the problem, one serious and one in jest:
My example is very simple. If I sock you in the nose, then I deserve to be socked in the nose. Do you disagree that is justice, fairness, equity?
It is simple, but it is also particularly bad. Here's a few reasons:
- There is no significant consensus that such an act would be just.
- It involves a kind of vigilante justice, which is commonly perceived to be problematic.
- It badly conflates retribution with revenge.
- It intentionally conflates three distinct things: retribution, rehabilitation, and deterrence.
- Opinions on the example are (therefore) highly unlikely to yield any progress or common ground regarding the idea of justice.
I disagree that your example is about justice though. Keeping a promise isn't justice. Paying a fair wage is. What if your property is 100 acres? Thirty dollars isn't a fair wage for a yard that size, so you keeping your promise isn't justice. What if I do a terrible job? It isn't fair for you to have to pay me the full thirty dollars. Being a liar is bad, sure, but it isn't about fairness or equity.
First let's just remember that I explicitly used the qualifier "
ceteris paribus" in anticipation of sophism. Beyond that let's work through your answer logically:
I disagree that your example is about justice though. Keeping a promise isn't justice.
Why isn't keeping a promise just?
Paying a fair wage is just. That doesn't mean keeping a promise isn't. Granted, this is vacuous given your definition, for you are saying that paying a fair wage is fair. Indubitably.
What if your property is 100 acres? Thirty dollars isn't a fair wage for a yard that size, so you keeping your promise isn't justice.
So the fact that unjust promises are possible means that it isn't just to keep promises? Are you able to differentiate between an exception and a rule?
What if I do a terrible job? It isn't fair for you to have to pay me the full thirty dollars.
Again, this simply isn't an argument against the justice of promise-keeping. If I tell you that lakes are good for swimming, and you point to a frozen lake in Canada as a counterargument, you haven't contradicted my claim in any real way, you've just engaged in a bit of sophism.
Being a liar is bad, sure, but it isn't about fairness or equity.
It is also unfair and unjust to lie, but breaking a promise does not necessitate a lie.
And you don't think equity and fairness have intrinsic value?
It's a new thought of mine, but now that I'm thinking about it, no. Not
intrinsic value, anyways.
Imagine this:
Orel: My boss only paid me half of my paycheck!
Zip: Is that a problem?
Orel: Yes!
Zip: Because it's unjust (or unfair)?
Orel: No... Because you're supposed to be remunerated for labor.
Zip: Why are you supposed to be remunerated for labor? Because it's just, right, fair?
Orel: No...
Orel: Maybe it's a problem because we both agreed, contractually, to a certain wage.
Zip: Why do we have to honor contracts and promises? Because it's just, right, fair?
Orel: No...
Trying to run away from the intrinsic value of justice is a very strange position, indeed. Justice is a very difficult, broad, simple, and complicated idea.
