Mark me down as impressed! The history is solid, and the meter and verse is of surprising quality. An example on Platonism:
the Theorem, anyway, defines
a shape whose sides are perfect lines
(no width, and absolutely straight).
This figure one can contemplate;
but it exists as an Ideal
within the mind, not something real.
So artefacts are a delusion!
Thus, Plato came to the conclusion
that all the things we seem to see
are Shadows of Reality.
Perception's flawed, so think things out --
the Mind alone is free from doubt.
Not that I'm a world expert, but I didn't expect to learn so much, either. The history is very well-researched. (As you might expect from an author who has published many non-rhyming books on cosmology.) Muirden also uses margins liberally to add dates and names, little informative tidbits that don't fit into the verse.
This little book is also a terrific source for cute quotes. On "De Revolutionibus":
No other book, it can be said,
has caused more stir and been less read.
If you're reading this review, you're obviously thinking about getting The Cosmic Verses. Do it. You're in for a happy surprise.
