 In effect, Mellor’s idea is that the brain represents time by means of time: that temporally ordered events are represented by similarly temporally ordered experiences. This would make the representation of time unique. (For example, the brain does not represent spatially separated objects by means of spatially separated perceptions, or orange things by orange perceptions.) But why should time be unique in this respect? In other media, time can be represented spatially (as in cartoons, graphs, and analogue clocks) or numerically (as in calendars and digital clocks). So perhaps the brain can represent time by other means. One reason to suppose that it must have other means at its disposal is that time needs to be represented in memory (I recall, both that a was earlier than b, and also the experience of seeing a occur before b) and intention (I intend to F after I G), but there is no obvious way in which Mellor’s ‘representation of time by time’ account can be extended to these.
