Abstract

For anyone interested in the place of spatiality in Heidegger’s thinking, one of the key problems presented by Being and Time is Heidegger’s attempt, in §70, ‘to derive existential spatiality from temporality’1 – an attempt he himself referred to as ‘untenable’.2 This attempt turns out to not to be merely peripheral to Heidegger’s overall analysis, but is instead tied to certain central and problematic features in the argument of Being and Time, including its treatment of spatial and topographic concepts in general, that can themselves be seen as associated with the failure of the project attempted there. The argument of §70 does not raise questions only about Heidegger’s treatment of spatiality, however, but also regarding the notion of ‘derivation’ itself – about how and whether such derivation is indeed possible in general, and how the dependence that it entails might be understood
