at the same time, language allows constructing impossible contradictions that are not obviously impossible just by knowing the words, yet are impossible in the real world, like the chicken/egg problem. brute thinks that qualia is such a word.
maybe it is appropriate to talk about the definition of "to exist". it's probably a hairy one. brute is willing to admit that reality probably exists, if by definition. things exist in reality.
but concepts invented by humans exist only to the degree that humans believe in them, they are literally made up. some of them describe reality well to a degree. none of them do so fully.
thus, when brute doesn't believe in qualia, he doesn't refute that the word exists, or that humans talk about it, or that daylen thinks he experiences qualiae (?). brute is hinting that this might be one of those cases where it's easy to say the word and think it describes something real, but doesn't actually describe anything meaningful.
and brute says this not being the biggest fan of reality to begin with.
