Supernatural and Philosophy: Metaphysics and Monsters... for Idjits - William Irwin, Galen A. Foresman

No doubt the years hunting monsters and saving the universe have had their toll on the Winchesters, but their toughest and most gruesome battles are contained in this book. Think Lucifer was diabolically clever? Think again. No son is more wayward than the one who squanders his intellect and academic career pursuing questions as poignant as “Half-awesome? That’s full-on good, right?” Gathered here for the first time since the formation of Purgatory, a collection of research so arcane and horrific that it would make even the late, great Bobby Singer blush.
