 The distinction between    types and tokens is crucial for understanding (1). A mental representation is a repeatable type that can be instantiated on different occasions. In the current literature, it is generally assumed that a mental representation’s tokens are neurological. For present purposes, the key point is that mental representations are instantiated by mental events. Here we construe the category of   events broadly so as to include both occurrences (e.g., I form an intention to drink orange juice) and enduring states (e.g., my longstanding belief that Abraham Lincoln was president of the United States). When mental event e instantiates representation S, we say that S is tokened and that e is a tokening of S. For example, if I believe that whales are mammals, then my belief (a mental event) is a tokening of a mental representation whose meaning is that whales are mammals.
