  The problems encountered by the Discrete Block theory and Broad’s hybrid model point the way forward to a more promising Extensional account. Recall the problem of ‘missed transitions’ that afflicts the Discrete Block model: in the case of the succession of tones C-D-E-F, although C and D are experienced as phenomenally continuous, E and F likewise, D and E are not – for unlike [C-D] and [E-F] they do not fall within the confines of a single specious present (see Figure 7). There is a simple remedy for this problem: the omitted transition can be restored by positing that [D-E] itself forms a single specious present – a further ‘duration block’ in the manner of Sprigge and Bradley – which for convenience we can call SPX. Since (by hypothesis) D-E is an experienced succession, this stipulation is well-motivated on the phenomenological level. What is more, this useful result has been achieved without recourse to Broad’s momentary-act/extended content conception of the specious present: the account remains fully (rather than merely partially) Extensionalist.
