Tractatus Logico-Philosophicus
Bachmann's doctoral dissertation expresses her growing disillusionment with Heideggerian existentialism, which was in part resolved through her growing interest in Ludwig Wittgenstein, whose "Tractatus Logico-Philosophicus" significantly influenced her relationship to language. During her lifetime, Bachmann was known mostly for her two collections of poetry, "Die gestundete Zeit" and "Anrufung des Grossen Bären".
