I'm not sure if you're joking or just not familiar with _why, but his book on Ruby is probably his most famous writing:

or
It's an incredible work.
Ruby is the spiritual successor to Perl, and the niche it filled was to be the "beautiful" programming language. If you don't appreciate _why's guide and the idea of code as magical incantations, you're not going to enjoy your Ruby experience. I don't think there's many rubyists that didn't appreciate _why.
With something as weird as Ruby, where there's so many ways to do everything, you're going to want to start with beginner's mind anyway.
