Leaving gymnasium to study philosophy, psychology and sociology at Johann Wolfgang Goethe University in Frankfurt, Adorno continued his readings with Kracauer, turning now to Hegel and Kierkegaard, and began publishing concert reviews and pieces of music for distinguished journals like the "Zeitschrift für Musik", the "Neue Blätter für Kunst und Literatur" and later for the "Musikblätter des Anbruch". In these articles Adorno championed avant-garde music at the same time as he critiqued the failings of musical modernity, as in the case of Stravinsky's "The Soldier's Tale", which in 1923 he called a "dismal Bohemian prank". In these early writings he was unequivocal in his condemnation of performances that either sought or pretended to achieve a transcendence that Adorno, in line with many intellectuals of the time, regarded as impossible: "No cathedral", he wrote, "can be built if no community desires one." In the summer of 1924 Adorno received his doctorate with a study of Edmund Husserl under the direction of the unorthodox neo-Kantian Hans Cornelius. Before his graduation Adorno had already met his most important intellectual collaborators, Horkheimer and Benjamin. Through Cornelius's seminars, Adorno met Horkheimer, through whom he was then introduced to Friedrich Pollock.
