Explain the work of the philosopher Hilary Lawson and the concepts of "non-realist metaphysics", the "openness" of the world and human "clos

If you decide to "close" the concept of a solid brick wall as if it were a shimmering curtain of mist and attempt to walk through it, the result will not be a triumph of non-realist metaphysics—it will be a broken nose. The most striking weakness in Lawson’s theory of "closure" is that the world possesses a stubborn **resistance** that doesn't care about our mental nets. If the world were truly an unstructured "openness," any way of dividing it up should be equally valid, yet nature constantly says "no" to our mistaken categories. ## The "No Miracles" Argument The most powerful objection to Lawson comes from the philosopher [Hilary Putnam](https://en.wikipedia.org/wiki/Hilary_Putnam), who proposed what is known as the **No Miracles Argument**. Putnam argued that if science were merely a set of useful "closures" or stories we tell about an unstructured world, the incredible success of modern technology would be a literal miracle. > "The positive argument for realism is that it is the only philosophy that doesn't make the success of science a miracle." — Hilary Putnam, *Mathematics, Matter and Method* Think about your smartphone. It relies on the behavior of subatomic electrons that no human has ever seen. If these "atoms" were just arbitrary boundaries we drew in a chaotic ocean, why do they behave exactly according to our mathematical predictions every single time? Realists argue that we aren't creating these structures; we are **discovering** them because they are actually there. ## The Unreasonable Effectiveness of Mathematics Lawson suggests we impose order on a "pre-conceptual" reality. However, this fails to explain why the world follows rigid mathematical laws that we often discover long before we find a "use" for them. The physicist [Eugene Wigner](https://en.wikipedia.org/wiki/The_Unreasonable_Effectiveness_of_Mathematics_in_the_Natural_Sciences) famously wrote about this phenomenon. If the world has no inherent structure, why does a mathematical formula derived on a chalkboard predict the existence of [Black Holes](https://science.nasa.gov/universe/black-holes/) or gravitational waves decades before we have the technology to see them? If we were just "inventing" the world through closure, the universe should not be able to surprise us with complex, pre-existing patterns that fit perfectly into the logic of prime numbers or calculus. ## Evolution: The Ultimate Reality Check From a biological perspective, Lawson’s theory faces a "survival of the fittest" problem. If the world were a structureless mystery, an organism that "closed" a predator as a "friend" would immediately be removed from the gene pool. Natural selection acts as a brutal filter. Our senses and brains didn't evolve to create "useful fictions" out of thin air; they evolved to track **objective features** of the environment—like gravity, caloric density, and physical threats. As the philosopher [John Searle](https://en.wikipedia.org/wiki/John_Searle) argues in his defense of [External Realism](https://plato.stanford.edu/entries/realism/), the very fact that we can communicate and survive in a shared environment suggests we are interacting with a world that has its own fixed, independent properties. While Lawson challenges us to remain humble about our knowledge, the "sharp edges" of the universe suggest that while we might choose the words, we certainly didn't invent the reality.
