 Moreover, he had a well worked out doctrine concerning the limitations of reason, and often points out that we should not expect fully to understand God’s workings, for God is, after all, “&lt;a Being&gt; of a most Primary and most singular Nature” (BP 2:107, 2:37, BOA § 4.1, p 357). (For different interpretations of Boyle on the limits of reason see Wojcik 1997, Holden 2007 and Marko 2014.) Furthermore, he was willing to admit the impossibility of our understanding — at least given the present limitations on our intellects — even quite ordinary and lawlike matters, e.g., the way in which the human soul and human body interact. How God could have created the world, and how it is that he can intervene in it, are matters as mysterious to us as how mind and body can interact, and that is a total mystery.
