Goodbye,Descartes

[luckyme]

A few years back a friend recommended "Goodbye, Descartes". I settled in for a good read .. until I reached page 44 and --
"No horned animal is a unicorn."
"All unicorns are horned animals."
-------------------------------
"Some unicorns are not horned animals."

I actually put the book down after that page, thinking that it was a simple equivocation error and not wanting to read a book that slipped into one on page 44 and used it as an example of "Aristotle's error."

I saw a reference to the book recently and now I'm wondering if I was too hasty in not finishing the book.

any opinions? luckyme
