Questing for the essence of mind and pattern

Just when I thought I might actually be able to cross off all the books on my to read list 2007 before the end of the year, brotherdearest comes by to lend me another book by Douglas R. Hofstadter. I don't know if I can resist putting this book on top of my list. Hofstadter is known and loved by nerds worldwide because of his masterpiece Gödel, Escher, Bach: an eternal Golden Braid which I loved with a passion.
But I will try to stick to my original plan and save this one for next year: Metamagical Themas: questing for the essence of mind and pattern. Oh how I wish I had unlimited time to read.
