In reply to lorenzo_pickle:
Lauren, whether or not your title derives from Blake, I'd say most people would immediately think you're making some reference to the concept of Materialism that relates to Decartes' ontological theory of being, or to the underpinnings of the Enlightenment belief in empiricism, or more recently Hegel and Marx (or is that Dialectical Materialism?). Either way, your title sounds to me like a critical theory student, struggling with an assignment!
