Abstract
The dispositional analysis of sentences ascribing powers and abilities to things and people runs into many difficulties. The situation is especially complex and confusing when such ascriptions are brought to bear on particular occasions, and carry some implication about the opportunities available on those occasions. Some of these difficulties are produced by superficial confusions, but I shall concentrate on those that beset any version of the dispositional analysis. Three difficulties will be examined, one presented by Lehrer, and two by Austin.Lehrer presents his difficulty as a refutation of Moore's dispositional analysis of “X could have acted otherwise”, which was “If X had chosen, he would have acted otherwise”. I shall introduce his objection by relating it to the distinctions drawn in Part I.· Expressed in my terminology, his point is that Moore's analysis presupposes that choosing is not an S-factor, and yet it might conceivably be an S-factor.
