The question about the eyes of Holmes seems ultimately
wrongly worded. The color of Holmes's eyes depended on
Conan Doyle's will; it is a question of artistic
creation. So the question about that color should be
re-worded as the question about whether Conan Doyle
described that color and, if so, how he did it. But if
we re-word it and pose: did Conan Doyle described
Holmes's eyes as blue? There is surely one definite
true answer to the question.
Is the question about CH similarly ill-worded? If so,
who is the creator of CH's biography? Whose is CH the
fictional creation? It depends on the will of whom?
Cantor's? Is it a question of copyright?
I don't think Holmes and CH are comparable topics. If
we agree on this, all we can require from CH in order
to accept it as a definite question is that it be not
I dare say that if we grant that reals and the set of
all reals are not mere fiction characters, CH should
be accepted as a definite and not vague question.
