 “[W]e presume too much of our own abilities,” Boyle wrote, c. 1680, “if we imagine that the omniscient God can have no other Ends in the framing &amp; managing of Things Corporeal, than such as we Men can discover” (Boyle MS 198, fol. 120, BP 7:116, BOA §3.6.3, p 267). It follows at once that while simplicity may often be our best guide as to what working hypothesis to choose, we should not think it to be inevitably a reliable guide to truth.
