 Is such a disposition innate or acquired? It is possible, according to Bonaventure, to find authorities on both sides of the debate. For the opinion that conscience is innate, Bonaventure cites, among other authorities, St. Paul’s famous reference to a moral law that is “written on [men’s] hearts” in Romans 1:14–15. He also appeals to a “natural instinct to seek blessedness and [to] honor [one’s] parents” (commentary on the Sentences, 2.39: a. 1, q. 2; McGrade trans. 2001: 175–176). For the opinion that conscience is not innate, on the other hand, Bonaventure cites Aristotle’s claim that the soul is a blank slate. Bonaventure’s solution is to find a middle position between St. Paul, on the one hand, and Aristotle, on the other. His conclusion: conscience is part innate, part acquired.
