 This is Broad’s version of an argument sometimes raised against the classical compatibilist conditional analysis of ‘S could have done  otherwise’.[12]  According to the classical compatibilist analysis this is to be understood simply as ‘if S had willed to act differently S would have acted differently’. The argument shows that this will not do: there are situations where an agent would have acted otherwise if she had willed differently but nonetheless could not have acted differently simply because she could not have willed to act  differently.[13]
