Perhaps even what we now call the laws of nature will be found to vary from one subuniverse to another. In that case, the explanation for the constants and laws that we have discovered may involve an irreducible historical element: the accident that we are in the particular subuniverse we inhabit. But, even if there turns out to be something in these ideas, I do not think that we will have to give up our dreams of discovering final laws of nature; the final laws would be megalaws that determine the probabilities of being in different types of subuniverse.
