  Many Retentional theorists have eschewed the Non-Modal option in favour of the Modal alternative. Since on this view only a small portion of a single specious present is experienced as fully present, the problem of surplus content is greatly diminished. The adoption of temporal modes also offers a promising-looking solution the Retentional Simultaneity problem: by virtue of appearing under different temporal modes, the contents of a single specious present will not seem to be simultaneous, even if this is what they are, objectively speaking. As for how temporal modes are to be conceived, Retentional theorists have outlined a variety of proposals.
