because q), for some q. 2 Such knowledge can be also acquired via testimony. Thus, (K-WHY ≠ CAS).Pritchard's argument for (U-WHY = CAS) is based on two assumptions: (i) Having a sound explanatory story regarding how cause and effect are related is a necessary requirement for understanding-why. (ii) Having (p because q) information is not equivalent to having such an explanatory story. He then argues that having an explanatory story regarding how cause and effect are related is a kind of CAS and that therefore (U-WHY = CAS).These arguments can be questioned in at least two different ways. Stephen Grimm (2006Grimm ( , 2014, Christoph Kelp (2014), andPaulina Sliwa (2015) argue that coming to believe that (p because q) also requires having an explanatory story regarding how cause and effect are related. If they were right, Pritchard's argument for (K-WHY ≠ CAS) would fail, according to his own criteria. If having an explanatory story regarding how cause and effect are related is a kind of CAS, then (K-WHY = CAS) and (U-WHY = CAS). Grimm (2012), Daniel Whiting (2012), and J. Adam Carter and Emma Gordon (2014) argue that having an explanatory story regarding how cause and effect are related is not a kind of CAS. If so, Pritchard's argument for (U-WHY = CAS) would fail. Then, it seems that (K-WHY ≠ CAS) and (U-WHY ≠ CAS). Either way, being a kind of CAS would not be a feature that sets understanding-why apart from knowledge-why. So, the crucial questions are: Does acquiring (p because q) information require having an explanatory story regarding how cause and effect are related? Is having an explanatory story regarding how cause and effect are related a kind of CAS?In this paper, I argue that both questions should be answered in the negative. After introducing the concept of a CAS (section 2) and after presenting Pritchard's argument for (K-WHY ≠ CAS) in more detail (section 3), I first elaborate on the explanatory story requirement (section 4). Having a sound explanatory story regarding how cause and effect are related is to have information about facts or principles that establish the causal connections between the phenomena in question. Then, I make a positive case for the claim that coming to believe that (p because q), for some q, does not 2 I use round brackets to avoid scope ambiguities with respects to 'know'.
