  In Being and Time, the most fundamental a priori transcendental condition for there to be Dasein's distinctive mode of Being which is identified is temporality. In the later philosophy, the ontological focus ultimately shifts to the claim that human Being consists most fundamentally in dwelling. This shift of attention emerges out of a subtle reformulation of the question of Being itself, a reformulation performed in the Contributions. The question now becomes not ‘What is the meaning of Being?’ but rather ‘How does Being essentially unfold?’. This reformulation means (in a way that should become clearer in a moment) that we are now asking the question of Being not from the perspective of Dasein, but from the perspective of Being (see above on abandoning subjectivity). But it also suggests that Being needs to be understood as fundamentally a timebound, historical process. As Heidegger puts it: “A being is: Be-ing holds sway [unfolds]”. (Contributions 10: 22. Quotations from the Contributions will be given in the form ‘section: page number’ where ‘page number’ refers to the Emad and Maly English translation. The hyphenated term ‘be-ing’ is adopted by Emad and Maly, in order to respect the fact that, in the Contributions, Heidegger substitutes the archaic spelling ‘Seyn’ for the contemporary ‘Sein’ as a way of distancing himself further from the traditional language of metaphysics. This translational convention, which has not become standard practice in the secondary literature, will not be adopted here, except in quotations from the Emad and Maly translation.)
