Hey guys, I've been studying UPB recently and am now finally beginning to really understand it. It makes a lot of sense although I still do have some minor reservations. Although the logic is sound I will still do more research to make sure there are no obvious holes in it. Any ethical theory of course has to overcome the mental gymnastics of ethical relativists and subjectivists. I have been a libertarian for a long time but have recently been looking for strong ethical frameworks to explain it. My question is are there other philosophers that have picked up on UPB and subscribe to it? I understand that it is a relatively approach to libertarian ethics but I was wondering if anyone else has come to adopt it.
