'Popper restricted falsification (which he equates to refutability) to empirical statements, and declared, "philosophical theories, or metaphysical theories, will be irrefutable by definition". He also noted that certain empirical statements are irrefutable. These are statements that he called "strict or pure existential statements." On the other hand, "restricted" existential statements are refuted. He gives this example:
"There exists a pearl which is ten times larger than the next largest pearl." If in this statement we restrict the words "There exists" to some finite region of space and time, then it may of course become a refutable statement. For example, the following statement is obviously empirically refutable: "At this moment and in this box here there exist at least two pearls on of which is ten times larger than the next largest pearl in this box." But then this statement is no longer a strict or pure existential statement: rather it is a restricted existential statement. A strict or pure existential statement applies to the whole universe, and it is irrefutable simply because there can be no method by which it could be refuted. For even if we were able to search our entire universe, the strict or pure existential statement would not be refuted by our failure to discover the required pearl, seeing that it might always be hiding in a place where we are not looking."
By this criterion, it would seem that the existence of God cannot be empirically refuted because to do so would require making an existential statement applying to the whole universe (plus whatever lies beyond). But, in looking at Popper's example, we see this is not the case for God. True, we cannot refute the existence of a God who, like the pearl in Popper's example is somewhere outside the box, say, in another galaxy. But God is supposed to be everywhere, including inside every box. So when we search for God inside a single box, no matter how small, we should either find him, thus confirming his existence, or not find him, thus refuting his existence [by failing to refute the null hypothesis].'
