Marx began work upon a book detailing his new philosophy of history, entitled The German Ideology.[2] In connection with this project, Marx wrote a terse 11-point set of observations and epigrams regarding the ideas of Ludwig Feuerbach, a fellow Young Hegelian philosopher regarded by him as the most modern exponent of materialism, albeit one whom Marx believed had failed to draw fully satisfactory political conclusions from his philosophical insights. These "theses" were initially written as a raw outline for the first chapter of The German Ideology, and most of these were developed at greater length in that work.[2]
