The reference to Rudolf Haller was refreshing, as his collection of Wittgenstein essays provide numerous means to interpreting his work, from out of various traditions in philosophy. Haller’s essay on the history of “Austrian Philosophy,” is really illuminating, as well as the brief essay on Spengler. I also appreciate Janik’s encouragement to read Hertz and Boltzmann, for I want to spend more time with the “natural scientists” responsible for influencing Wittgenstein’s thought.
