Big ups to Bill Irwin, a.k.a. The Bountiful Producer, for being down with this project from the get-go and to Bill Lawson and Eddie Glaude for suggesting we take it on. Much respect to our almighty posse of philosophers for their faith in us, patience, hard work, and amazing creativity in moving from rhyme to reason. Big ups to the Open Court crew, especially to David Ramsay Steele, a.k.a. Da Voice in da Machine, for sage advice and for hyping us to rock the boulevard and the bourgeoisie. Props to Zick Rubin for doing what he does so well. Good lookin' out 2! Props also to Lidet Tilahun for research assistance. We are grateful to our home institutions, Harvard University and Texas A&M University, for their financial support of this project. We learned much from our many friends, colleagues, and students who have talked to us about the pleasures and perils of mixing hip hop and philosophy. Most of all, we want to thank our loving wives, Angela and Jessie, for their unwavering support as we worked on this book and for enduring our many long late night phone conversations about all things hip hop and philosophy. Peace, y'all!
