I agree that that statement is what you disagree with. But I don’t know what you mean by it. I personally don’t feel comfortable saying the aggregates are ontologically/fundamentally/literally/independently anything in particular. Especially because I have noticed that you tend to interpret certain common words in ways that imply metaphysical views on part of the speaker. I don’t know how you personally assign views to particular words and phrases, so I would not agree that we have an understanding of the issue at hand.
This is why I would like to understand how you define “dukkha.” Because one thing I’ve noticed in some of the threads and comments about this topic is that the meaning of “dukkha” doesn’t seem to ever be discussed between the parties. Only the meaning of “literal” and “fundamental” and “core” and “aggregates” and “ontological” and “mere” and so on are discussed. But we are supposed to be talking about dukkha. So what are we talking about?
In short, no, I don’t believe your contention is a mistake. Because I don’t fully understand the arguments being proposed. I have some guesses and suspicions about what people mean. But that’s about it right now.
Not in a pejorative sense, as I think you were trying to make a meaningful distinction. I just think that the conversation could be reduced to language games and that it lacked any kind of clarity or coherency without further clarification of what we are really talking about. It seemed more rhetorical (not just on your side) than meaningful. But I would not suppose that you were trying to avoid meaningful discourse. So I assume instead that we are not on the same page about what these terms refer to.
