I posted it because I think this happens very frequently on HN - long and unproductive backs-and-forths that only exist because someone used a "landmine" word, and someone else stepped on it.
And by the way, if you are going to post things and then downvote legitimate responses—then perhaps you need to rethink things a bit?
TeMPOraL didn't downvote you. He couldn't. No one can downvote replies to their own posts (see https://news.ycombinator.com/newsfaq.html).
https://news.ycombinator.com/item?id=25969116 was probably downvoted because it broke these guidelines:
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
My take on this is that it isn’t an issue of whether you can discuss truth or not, but rather if it’s philosophically relevant to the conversation. What I mean by that, and what I think the article means, is that the person isn’t questioning the meaning of truth really but instead avoiding the discussion going really any further by throwing out a catch phrase which is pertinent in a very distant and vague sense, but the person has no real intent to go into it.
It’s sort of seems like a form of “whataboutism” where somebody counters a point by going “Yeah but what about truth?!” It effectively ends the conversation because it’s not a matter of agreeing on the meaning of truth in the context of the discussion, but more of a distraction which can never be fully answered which stalls the original discussion.
Maybe in context those specific definitions do matter and should be stated assumptions, but often I don’t think they are. In addition, it truth or morals can’t be pinned down in centuries of effort, how could they be in these kinds of conversations? I don’t believe they could.
