12. This train, the measure of other successions.
So that to me it seems, that the constant and regular succession of
ideas in a waking man, is, as it were, the measure and standard of all other successions. Whereof, if any one either
exceeds the pace of our ideas, as where two sounds or pains, etc., take up in their succession the duration of but
one idea; or else where any motion or succession is so slow, as that it keeps not pace with the ideas in our minds,
or the quickness in which they take their turns, as when any one or more ideas in their ordinary course come into
our mind, between those which are offered to the sight by the different perceptible distances of a body in motion,
or between sounds or smells following one another,--there also the sense of a constant continued succession is
lost, and we perceive it not, but with certain gaps of rest between.
