i think of it like this:

the self needs to be actualized by another person's recognition of them. it isn't something we can do for ourselves. that "know thyself" thing can only go so far. there has to be somebody else who knows who you are. if nobody else knows you, your authentic self, it is sort of like not existing at all. and i think sometimes even the self can't know until somebody else validates and confirms us. realization. actualization. that's justice. it's justice because the only thing that ever feels right is actualization of authentic self. without that, everything feels wrong. even if we learn to cope with that sort of discontent, we still keep needing that actualization.

ya, i've rambled. i hope you understand what i'm saying. or i hope i haven't made it confusing.
