“ if Nothingness can be conceived neither outside of Being, nor in terms of Being, and if on the other hand, since it is non-being, it can not derive from itself the necessary force to “nihilate itself,” where does Nothingness come from ?
If we wish to pursue the problem further, we must first recognize that we can not grant to nothingness the property of “nihilating itself.” ”
