True, true.The idea that we can discuss nothing because everything is in question becomes its own type of circular logic if allowed.
I remember a professor that told us that art is a term that you just cannot turn to the back of a book or look up in a dictionary and make it true for everyone. Some aspects of life have to be lived, not looked up.
That said, I used to make the argument about whether a pipe was worth as much if you removed the brand or name of the maker. If that pipe was unnamed and found in a junk drawer, it probably wouldn't have any value, IMO. Neither would a Dunhill or Becker. However, as attached to a maker... maybe, maybe not. Whether it would bring the same joy, is purely in the heart of the individual. No matter what objectivity/subjectivity that is placed on the pipe, the joy and value lies somewhere between the tobacco and the smoker.
