explain your position in terms of feelings of meaning and purpose
This is a fundamental error. Neither meaning nor purpose are feelings.
Agreed. I never said they were.
The word "meaning" has come up in two contexts - "If the universe had no meaning" and "meaning for otherwise inexplicable disasters".
In both cases the only way to decide whether a statement accurately specifies the "meaning" of "the universe" or the "disaster" is by the emotional reaction of the listener to the statement - the feeling the statement evokes in the listener.
Part of my job is a compiler writer and I have a B.Sc(Hons) in mathematics, including a major component in symbolic logic. I fully understand the concepts of syntax, semantics, and noise -and the fundamental point in these disciplines is to have an system, a model of that system, and to compare the system and the model in a rigorous non-emotional manner. Concepts such as "the meaning of the universe" do not have a non-emotional comparitor.
An interesting and eclectic agglomeration of qualitatively different things. For one who values logic so highly, you are extremely careless with your categories
Earlier, you wrote...
But these explanations supply two crucial ingredients: purpose and hope.
These are also lists of qualitatively different things. I did not misconstrue these constructs as your being careless with your categories.
My list of "emotional-pleasantness, purpose/meaning, being part of an elite social group" was deliberately supplying differing dimensions, and I am surprised you misconstrued it as my being careless with categories.
To former generations it would have been considered self-evident that a worldview consisting entirely of two categories 1)Whatever is measurable and 2)everything else, is clearly missing something
It was also self-evident that the Earth was the center of the universe.
Furthermore, it is possible to have a worldview that can support categorizing things in several different ways : measurable/immeasurable, real/imaginary, logical/illogical, pretty/ugly, big/small, hot/cold, ...
