This article deals with Heinrich Böll’s contribution to the complex topic of migration and refugees in the German post-war society. In particular, this paper focuses on the short story Du fährst zu oft nach Heidelberg and some of the author’s essays and interviews. Central in this respect is Böll’s poetics of humanity, which encourages solidarity, pietas and fraternity and represents a merciless fight against the oppression of the status quo and the hypocrisy of contemporary Germany. The outsiders, with whom Böll feels an inalienable solidarity, become the focus of his subversive writing and a literary device to foster individual responsibility and internationality.
