He was not a writer but a sociologiest. He lived in a time when sociology was growing as a discipline. After examining the contradictory life of a musician, he wrote an interesting book, "Upon the sociology of a genius, Motzart" (this doesn't seem to make sense. what did you really want to say?). In this work, he tried to depict the musician by means of sociology (it's redundant to add methods since means=methods). The book, to some extent, proved to bear resemblance to a document of scientific qualification that described the various human situations of a genius.
Moreover, it portrayed the desperation of a man by enriching real-life experiences.
