In this paper, I will discuss the idea of contrastive explanandum. I will restrict my discussion to singular causal explanation, but the basic ideas and the arguments have a broader application. They are relevant also to other kinds of explanations. In the first section I will first present the intuitive idea of contrastive questions, and then elaborate it by discussing typical criteria for the choice of a contrast. I also suggest a novel way to see the difference between scientific and everyday explanatory questions. In the second section I will discuss the major criticisms presented against contrastive theories of explanation in order to further clarify my position. I argue that all explananda can be analyzed as contrastive and that this is a fruitful approach in understanding explanatory questions. I also argue that the contrastive thesis should be understood as a claim about what an explanation can explain, not as a thesis about what the explainee has in her mind. Finally, I defend the thesis that a contrastive explanandum can be reduced to a non-contrastive explanandum against the arguments presented by Dennis Temple and John W. Carroll.
The contrastive explanandumA famous joke about the bank robber Willie Sutton introduces the basic idea of contrastive explanation. When Willie was in prison, a prison priest asked him why he robbed banks.Willie answered, "Well, that's where the money is." The joke is based on a confusion, for Willie was not answering the question the priest was asking. The priest had in his mind the question: "why do you rob banks, instead of leading an honest life?", whereas Willie answered the question: "why do you rob banks, rather than gas stations or grocery stores?" This is the basic insight of the contrastive approach. We do not explain simply 'Why f?' rather, our explanations are answers to the contrastive question 'Why f rather than c?'. (Garfinkel 1981: 21-22.) Instead of explaining plain facts, we are explaining contrastive facts.Several philosophers of explanation have used the same basic idea. (For example, Hart & Honoré 1959; Hansson 1975; van Fraassen 1980;Garfinkel 1981;Hesslow 1983; Woodward Published in 2007 2 1993 (originally published in 1984); Lewis 1986;Sober 1994 Sober (originally published in 1986Temple 1988; Lipton 1990Lipton , 1991Lipton , 1993Barnes 1994;Hitchcock 1996Hitchcock , 1999Carroll 1997Carroll , 1999Risjord 2000.) I will follow their lead and try to develop the contrastive idea a little bit further.In the following discussion I am not committed to any specific theory about explanationseeking questions. (See van Fraassen 1980; Tuomela 1980;Sintonen 1984; Koura 1988;Hintikka & Halonen 1995.) Some advocates of the contrastive approach subscribe to the thesis that all explanatory questions are always why-questions (van Fraassen 1980). The account presented here does not include any such commitment. The thesis that explanations are answers to questions should be kept separate from the thesis that all explanation-seeking questions are why-questions. A...
