Actuality is a state or condition of being real, effectual, or actuated (i.e., “at work”). Unlike Dasein and the occurrent (Vorhandene) in Heidegger’s early period, or the fourfold (Geviert) and (thing) in the later works, actuality (Ding) in the later works, actuality (Wirklichkeit) in the later works, actuality (Wirklichkeit) does not typically behave like a technical term in Heidegger’s oeuvre; nor does it name one of Heidegger’s own abiding topics, except in contexts where Heidegger is creatively appropriating the thought of his predecessors.
