 All contextualists accuse the sorites monger of equivocating. In one sense, the meaning of ‘child’ is uniform; the context-invariant rule for using the term (its “character”) is constant. However, the set of things to which the term applies (its “content”) shifts with the context. In this respect, vague words resemble indexical terms such as: I, you, here, now, today, tomorrow. When a debtor tells his creditor on Monday ‘I will pay you back tomorrow’ and then repeats the sentence on Tuesday, there is a sense in which he has said the same thing (the character is the same) and a sense in which he has said something different (the content has shifted because ‘tomorrow’ now picks out Wednesday).
