Temporal experiences, according to retentionalism, essentially have temporally extended contents: contents which represent distinct events at distinct temporal locations, and some of their temporal relations. This means, retentionalists insist, that temporal experiences themselves needn’t be extended in time: only their contents are. The paper reviews an experiment by Moutoussis and Zeki, which demonstrates a colour-motion visual asynchrony (§2): information about motion seems to be processed more slowly than information about colour, so that the former is delayed relative to the latter. (...) This, the paper argues, raises an important difficulty for retentionalism and its account of the temporal ontology of experiences: it suggests that a central background assumption about neural processing presupposed by retentionalism is false, at least in cases of visual asynchrony. The paper then explores the general significance of this result for retentionalism (§3). (shrink)

Drawing on the 1870s-1880s work of Shadworth Hodgson and Robert Kelly, William James famously characterised the specious present as ‘the short duration of which we are immediately and incessantly sensible’. Literature on the pre-history of late nineteenth century specious present theories clusters around the work of John Locke and Thomas Reid, and I argue it is incomplete. The pre-history is missing an inter-connected group of English philosophers writing on the present between 1749 and 1785: David Hartley, Joseph Priestley, Abraham Tucker, (...) and William Watson. With William Herschel, Watson even conducted experiments to determine the limits of human temporal perception. These thinkers do not appear in the specious present literature, or broader historical surveys of temporal consciousness. Yet this paper shows that they all produced important work on our experience of the present, variously defending theses that can be found in subsequent specious present theories. It argues their texts reward study, and may have influenced later theorists; contextualises the nineteenth century theories of James and others; and pushes back the start date of the 'standard history' of micro time by over half a century.
