Ordinarily I like the stuff R.A.Wilson writes. This time, though, he has written not a book, but a series of 'filler' paragraphs. No subject is studied enough to satisfy and some subjects are left so incomplete I wonder what he was thinking when he wrote it. I would have nuch preferred a book that delved more deeply into several (or more) of the subjects he covered incompletely. A nice try but if I could I would return the book because it was so disappointing.
