  How does the property of presentedness work? How does one phenomenal characteristic manage to make one or more other phenomenal characteristics appear to be less than wholly present? The question is of interest because the only obvious way of construing ‘different degrees of presentedness’ is in terms of different degrees of Humean force and vivacity: a memory-image of a red balloon could easily be described as seeming ‘less present’ in this sense than a perceptual experience of a red balloon. But thus construed presentedness fails to do the job required: the upper parts of the specious present depicted in Figure 16 evidently possess less force and vivacity than those lower down, but they don’t seem in the least less present (in the temporal sense) as a result. Since Broad is silent on this issue, he presumably takes presentedness to be a primitive property, whose character and mode of functioning cannot usefully be elucidated. Nonetheless, it remains mysterious how any phenomenal property could do the work required.
