La ideología alemana
Marx began work upon a book detailing his new philosophy of history, entitled "The German Ideology". In connection with this project, Marx wrote a terse 11-point set of observations and epigrams regarding the ideas of Ludwig Feuerbach. Feuerbach was a fellow Young Hegelian who Marx regarded as the most modern exponent of materialism, although Marx believed Feuerbach had not drawn 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.
