Fore-having (Vorhaben), a component of hermeneutic circle, is not given a detailed explanation in Being and time. In Ontology: the hermeneutics of facticity, which is based on a lecture course and lecture notes written by Heidegger in 1923, four years before the publication of Being and time, we get more clues as to what the German philosopher really meant by fore-having. It turns out that fore-having is the factical being-in-the-world of Dasein – factical in that Dasein is there, is a there-being – and hence relates to the “worlding” of Dasein as a non-solipsistic being who is interrelated with others and all that is accessible to its senses in regard to other forms of beings on earth.

The “worlding” of my being as Dasein is my fore-having in hermeneutic circle; understanding and interpretation, the two fundamental aspects and issues of hermeneutics, stem from this facticity. And as Heidegger elucidates in Being and time, the phenomenon of Jemeinigkeit indicates that Dasein is first and foremost mine. This substitutes the vexing problem of “consciousness” in the dualistic schema of traditional metaphysics, which Husserl, the founder of the phenomenological movement, was himself unable to disentangle himself from.
