Existence / nothing / Nozick: If we assume instead of nothing the full existence as a natural state, we have to wonder how so many opportunities are not realized - then the present situation must be produced by a negating force - if then also nothingness is allowed depends on whether the force may be applied to itself - Western philosophy: holds existence somehow to be more perfect than nothingness - however perfection itself is not a natural state.
