Reality Does Not Take Instructions: Necessity, belief, and the limits of human knowledge

We often speak as though a convincing explanation settles what reality must be. Yet an explanationbelongs to our understanding, and our understanding is limited. This article explores a simple distinction:what our present knowledge requires us to assume is not necessarily a final account of what exists.Something can be unnecessary for an explanation without being nonexistent. Something else may seemnecessary only because we have not yet found a better explanation. Drawing on the history of physics,quantum mechanics, and Stephen Hawking's discussion of God, the article argues for care in moving fromknowledge to claims about existence. It distinguishes facts from our claims about facts, and revisablebelief from dogmatic certainty. Its central proposal is that judgments of necessity and non-necessity mustremain tied to the evidence and assumptions available to us today. We can investigate reality, but wecannot dictate to it what it must or must not be.
