 The challenge for antirealism is to minimize the havoc lawless reality would play with our folk and scientific practices. Regarding science, the examples and uses of laws described at the start of this entry attest to ‘law’ having a visible role in science that scientists seem prepared to take as factive. Regarding our folk practices, though ‘law’ is not often part of run-of-the-mill conversations, an antirealism about lawhood would still have wide-ranging consequences. This is due to lawhood’s ties to other concepts, especially the nomic ones, concepts like the counterfactual conditional, dispositions, and causation. For example, it seems that, for there to be any interesting counterfactual truths, there must be at least one law of nature. Would an ordinary match in ordinary conditions light if struck? It seems it would, but only because we presume nature to be regular in certain ways. We think this counterfactual is true because we believe there are laws. Were there no laws, it would not be the case that, if the match were struck, it would light. As a result, it would also not be the case that the match was disposed to ignite, nor the case that striking the match would cause it to light.
