Indeed, I'm not a fan redundancy either when I interact with people but I can tolerate it although I'm very aware of it. Now, it is true that Jack's renaming of some Reinin dichotomies seemed kinda redundant because they don't add meaning and/or clarity, on the contrary they add confusion. That said, I have a typical method of studying interesting abstract stuff*, I would say that there are two main phases in that process :
Phase 1) to explore all the sources I can find on the subject including people's opinions and work on that same topic in order to have a global vision of it and thus a better understand it (and when I say "people" I mean like Jean-Luc Godard would say "The professionals of the profession" !).
Phase 2) kicks in when I feel like I accumulated enough data on the subject and I naturally start to crash test the logic of these ideas and concepts to verify if they hold water and make sense. That's when I become quite critical and might surprise people because up to that moment, I was going with flow and basically learning like a disciple .
Sad story indeed. The problem with that procedure is the fact that it violates the
Prime Directive Hippocratic Oath . Furthermore, we can't help a mentally ill person to die just because that person is suffering mentally. I mean preventing suicide is one of the main point of psychiatry. So from that standpoint it's a nonsense and an insult to the Medical profession. That said, If the person is atrociously suffering physical pain and the chances for that person to get better are 0% then I am for that act of empathy. I mean we do it everyday to some family members, namely our pets, without it bringing moral or ethical controversy, on the contrary we find that "Human".
