Section 3.1.1 there discusses 2^aleph-null and C. Towards the end it
has some interesting quotes from mathematicians about the Continuum

undecideable, etc.
Also interesting is
http://www.ii.com/math/ch/confusion/
which discusses some of the misinformation floating around about the
Continuum Hypothesis, which has led to some of the confusion in our
discussion here.
