Input (English): One work by this philosopher uses the metaphor of a man in a boat to illustrate the futility of trusting Schopenhauer's principium individuationis to reduce suffering. That work's second edition contained a preface in which this man declared it an "impossible book" and regretted "ruining the problem of the Greeks" with modern aesthetic examples. Another book by this author of "An Attempt at Self-Criticism" claims that widespread literacy has caused writing to be diluted for the masses. That book describes an evolution from (*) camel to lion to child in the section "The Three Metamorphoses of Man". This man's first book contrasted the Apollonian and Dionysian aesthetics, while another of his books contains the metaphor of a tightrope walker to illustrate man's evolution towards the ubermensch. For 10 points, name this German philosopher who wrote The Birth of Tragedy and Also Sprach Zarathustra.
