The absence of any reason for my being

Even if I cannot think of myself, for example, as annihilated, neither can I think of any cause that would rule out this eventuality. The possibility of my not being is thinkable as the counterpart of the absence of any reason for my being, even if I cannot think what it would be not to be. [...] For even if I cannot think the unthinkable, I can think the possibility of the unthinkable by dint of the unreason of the real.
