"Der Wille zur Macht" was first translated into English by Anthony M. Ludovici in 1910, and was published in Oscar Levy's edition of Nietzsche's papers. The introduction of the most recent edition by Walter Kaufmann and R. J. Hollingdale offers both praise and criticism for Ludovici's edition, saying that, "Dr. Levy was probably quite right when in a prefatory note he called Ludovici 'the most gifted and conscientious of my collaborators,' but unfortunately this does not mean that Ludovici's translations are roughly reliable....Let us say that Ludovici was not a philosopher, and let it go at that."
