Paley's watchmaker argument is clearly not vulnerable to Hume's criticism that the works of nature and human artifacts are too dissimilar to infer that they are like effects having like causes. Paley's argument, unlike arguments from analogy, does not depend on a premise asserting a general resemblance between the objects of comparison. What matters for Paley's argument is that works of nature and human artifacts have a particular property that reliably indicates design. Regardless of how dissimilar any particular natural object might otherwise be from a watch, both objects exhibit the sort of functional complexity that warrants an inference that it was made by an intelligent designer.
