The talk explores Martin Heidegger’s largely neglected philosophy of courage. In his 1927 "Being and Time", Heidegger claims that the fallenness to which any "Dasein" is prone goes with a lack of a proper world. This manifests itself in the reign of the anonymous "They" [das Man] and in the absence of what Heidegger calls "the courage to be anxious" [Mut zur Angst]. The lecture shows how having a world is ultimately thinkable only under the condition of a peculiar readiness to lose it – something Heidegger describes as "Weg-sein", a being-not-there. Losing the world (in the right way) thus becomes the very condition for having one at all.
