Polymath,
You have been such a blessing!
One last question, "Do finitists make any distinction between sets ("collections") that are countable versus uncountable?"
Thanks,

Again, for a finitist, all sets are finite. So the issue simply doesn't arise. The definition of cardinality can be made, but it trivializes. No set is uncountable, no set is even countably infinite.
For a finitist, there *is* no set of natural numbers. There *is* no set of real numbers. ONLY finite sets exist in the finitist system.
I think you can see why most mathematicians see finitism as limiting.
