 For instance, Elgin, de Regt, and Wilkenfeld argue that those who grasp how things are connected are able to cognitively “do” things that others cannot—they can apply their understanding to new cases, for example, and draw new inferences. (See, for example, Elgin 1996: 122–24; de Regt 2004, 2017; Wilkenfeld 2013). Thus car mechanics who understand how engines work are able to make sense of engines that they have not encountered before, and to anticipate how changes in one part of the engine will typically lead (or fail to lead) to changes in other parts.
