But unless you already know what the dance is, how are you going to select whom to watch, and when? And it is not satisfactory to ask the dancers whether they (it take two to foxtrot) are doing the foxtrot, for they may claim to be doing so but may be in error. Similarly, many people may claim to be doing philosophy, or philosophy of education, but isn't it possible that they are mistaken? (Maybe they are guilty of wishful thinking.)
