But then I was taught a similar view of explanation, i.e., the specification of conditions both necessary and sufficient. What intrigues me about Abbot's *heuristic is that, in a properly social scientific manner, he does not assume that he knows what an explanation is. Instead, he looks at what is going on when people offer what they call explanations: Some are identifying bottlenecks in processes where effective intervention is possible. Some situate whatever is being "explained" in relation to what some scholarly community takes to be common sense. Some offer arguments that are elegant, surprising, or both. Whichever approach is adopted, the "explanation" proceeds until it suffices, i.e., until the scholar (or the community of scholars to whom the scholar belongs) says, "OK," and moves on to other projects. * None of these approaches satisfy the requirement of specifying both necessary and sufficient conditions. But if the philosophical approach at this point is nothing more than pointing a finger and scolding, that seems a bit infantile. In contrast, Abbot's approach offers the student some guidance in sorting out what it is that scholars are trying to do and what sufficing conditions must be met to call a project done and move on to something else. In an imperfect world where knowledge is always partial, this seems a useful contribution.
