Tsenay Serequeberhan’s hermeneutics has been crucial to the development of African philosophy. Initially employed as a pathway through the ethno- and professional philosophical debates, scholars have engaged how Serequeberhan’s hermeneutics grapples with one’s own place within a socio-historical world in service of liberation/self-determination. However, this scholarship mainly has focused on his adaptation of Gadamer’s ‘effective-historical consciousness’ for his own concept of heritage. This consequently leaves his concept of a ‘lived existence’ – which is equally crucial – under-examined. This paper probes what a ‘lived existence’ entails and its essentiality when explicating how one even begins to authentically think, which is the groundwork to Serequeberhan’s hermeneutics. This deepens why his concept of heritage matters as a starting point for self-determination. Addressing this lacuna, this article asks, where does philosophy begin and where should it go, particularly when rationality has been historically denied? Serequeberhan’s point of departure to answer this question proposes Heidegger’s concept of thinking itself to arrive at a notion of existence; contrariwise to most African scholars who employ a Sartrean existentialism via Frantz Fanon. As such, this paper gives an in-depth exploration of Serequeberhan’s initial reading of Heidegger, and then unfolds how he appropriates Heidegger to craft his notion of ‘lived existence’. The upshot this is twofold: First, a broader understanding of Serequeberhan’s project, its non-existentialist view of existence; Second, it describes how he specifically tailors his ‘lived existence’ to undergird his hermeneutical approach to heritage as a prescriptive, activist project which dynamically addresses the postcolonial situation.
