ABSTRACT
Logical differences between yes-no, alternative and word questions are determined, it has been seen, solely by the presupposition of the question. But it has also been noted how a question of one of these types can be recast as a question of a different type: occasionally a yes-no question can be worded as an alternative question — in everyday life, not merely at the behest of some theory; and an alternative question can readily be rephrased as a which question. Some explanation is required how a question can be phrased in a way at variance with its logical type as determined by its presupposition. The Aristotelian approach whereby a proposition is conceived as answering some question can be developed, it was seen, into a doctrine of interrogative concepts whereby objects of logical attention are conceived interrogatively.
