<i>&gt; They are reductions of reality</i><p>Sure, but that doesn&#x27;t mean they don&#x27;t match reality. It just means they don&#x27;t match <i>all</i> of reality; they leave information out. Of course all of our models have to leave information out, I agree with that. But that&#x27;s a separate question from the question of whether the information a given model includes matches the portion of reality it is intended to model--or, better, to how good an approximation a given model matches the portion of reality it is intended to model. That&#x27;s the whole point of Asimov&#x27;s essay.
