 In contrast to the ways in which such capacities have frequently been referred to in the slogan mode, particularly to the pathos that has tended to accompany it, it seems highly implausible that any one such property will stand alone as structurally significant. It is more likely that we should be picking out a constellation of properties, a constellation that may well include properties variants of which are possessed by other animals. Other properties, including capacities that may be specific to contemporary humans, such as humour, may be less plausible candidates for a structural role.
