Nietzsche's "drive theory", as it is referred to in the secondary literature, is a rich, unique and fascinating articulation of the human condition. In broad brushstrokes, Nietzsche appears to contend that all human psychology is either directly reducible to animal drives (e.g. sex, aggression) or indirectly explicable to the historical transformations thereof (e.g. ressentiment). Moreover, Nietzsche's initial elucidation of drive theory in On the Genealogy of Morals (and elsewhere) is well-complemented with a fecund, profound, and clear elucidation of the concept in the secondary literature.

Yet, there remains a glaring lacuna for all the discussion of drive theory in the scholarship. The secondary literature is delinquent in explaining how animal drives became incorporated to form the human psyche.  Nietzsche's account to elucidate how drives became "digested" or in his words "inpsychated" is called the Internalization Hypothesis. However, as it appears in GM:II, 16, the hypothesis is grossly inchoate. The result of this undertheorization is manifold; its deleterious effects resonate along many axes of Nietzsche's philosophy.

The present book, Internalized Valuation: A Genealogical Analysis of Nietzschean Drive Theory, offers an original and fruitful interpretation of Nietzsche's philosophical psychology. First, it clarifies what drives are. Second, it provides a new way of thinking about Nietzsche's genealogical methods and then applies these insights to The Genealogy itself. What follows is a work that not only sheds much-needed light on Nietzsche's philosophy of mind in general and his theory of emotions in particular, but also informs and illuminates problematic passages of Nietzsche's Genealogy.
