- In the definition of a set, one axiom is the existence
- of infinity. It is one of the usual Zermelo-Fraenkel
- axioms.
-
- Reading the book "infinity and the mind" by Rudy Rucker
- (by the way, it is delighting), one learns that
- there are many different types of infinities which
- exist, of different "size".
-
- Which of these is the infinity specified in the
- axioms of set theory ? Is it important to decide this
- question ? Does this have any effect on set theory ?
