Some of the hardest jobs in creating an authoritative evidence rack will be wording the propositions themselves, wording the evidence entries, and wording any associated annotations.
Atomic propositions themselves, however, are composed of strings of names that function, as Russell explained, in the strict logical sense; and atomic facts are composed of simple objects, the things that can thus be named.
Thus, the teaching authority condemned the heliocentric theory of Galileo as contrary to the Bible because it had always understood that revealed truth, in the context of current knowledge, may require one to accept or to reject certain propositions, though those propositions themselves are not part of revealed doctrine.
The facts of the world then consist of true propositions, themselves understood as complexes of concepts.
In this case, what changes is our access to the propositions in question, rather than the propositions themselves.
Apart from questions of tautology or indeterminate relations to observation, many hypotheses are derivable from propositions that are unfalsifiable because they cannot be tested without relying on conceptualizations which imply the propositions themselves.
It is perhaps worth noting that having sentences with different syntactic structures and containing words with different semantic values express different propositions doesn't require one to hold that propositions themselves are structured and contain the semantic values of the words as constituents.
In any case, nonspecialist listeners are given some basis to judge the merits of Ms. Thoene's proposition for themselves and wade knee-deep into a fascinating musicological thicket.
Instead of agitprop that would have little effect or abstraction that could be easily absorbed by the regime, Clark's propositions removed themselves from the realm of aesthetics.
