So I would say that justice, or law, is a necessary means for social union. The important question from my view, is determining what is a necessary law, which reflects the individuals and the collection of them. We can say that for anything we know. We both know we can know anything we learn, but it will be superficial in ultimate terms. We do not have to use instinct either.
Nothing is, because everything is, so the argument goes.
Yet, if everything is, then anything or somethings are fine is the way. Everything can be experienced in any way. It is not redundant because everything is, including conscious separation. Neither of us can be right or wrong. It can be seen in any number of ways.
