As I said much earlier this is an area of philosophy that I'm learning. Part of the learning process is to read about it, try to understand it, and then put it in words trying to discuss it...as best I can. It may well be that much of what I post is dead wrong, thus I start with someone else's write up on it and try to discuss it.
What I understand of it says it's important in understanding much of what the left thinks (or, better, feels) and says and does (in law).
If you're reading it, and getting anything out of it, then it's worth it and I'll continue.
