ABSTRACT
But the crucial question [about any logic of research] concerns, not the intrinsic virtues of the reconstructed logic taken in itself but rather its usefulness in illuminating logic-in-use. There is a story of a drunkard searching under a lamp for his house key, which he dropped some distance away. Asked why he didn't look where he dropped it, he replied, “If's lighter here!” Much effort, not only in the logic of behavioral science, but in behavioral science itself, is vitiated, in my opinion, by the principle of the drunkard's search.
