Abstract
There are statements and judgements which, prima facie, are generalizations but whose truth we maintain in the face of exceptions. ‘A cheetah can outrun a man.’1 Hobbled, injured and drugged cheetahs are cheetahs. Not all of these can outrun any man. Thus, although it is true that a cheetah can outrun a man, it is also true that not all cheetahs can do so. Is this a consistent thing to say?
