I am reminded of the following quote from the late E.T. Jaynes:
"Infinite set paradoxing has become a morbid infection that is today
spreading in a way that threatens the very life of probability theory,
and requires immediate surgical removal. In our system, after this
surgery, such paradoxes are avoided automatically; they cannot arise
from correct application of our basic rules, because those rules admit
only finite sets and infinite sets that arise as well-defined and
well-behaved limits of finite sets. The paradoxing was caused by (1)
jumping directly into an infinite set without specifying any limiting
process to define its properties; and then (2) asking questions whose
answers depend on how the limit was approached."

This, unfortuantely unfinished, book contains lots of thought-provoking
material.
