 In  section 2,  we outlined a number of ways in which a normativity condition might be thought to impose a constraint on accounts of meaning. We suggested that in all of these ways this condition puts at least prima facie pressure on dispositionalist theories of meaning. We will limit ourselves in the remainder of this section to some remarks on the finitude problem and the error problem. These two problems indicate two obstacles that the dispositionalist must overcome in order to meet the extensionality condition.
