— 184 —
The train of Ideas has a certain degree of quickness.       §9. Hence I leave it to others to judge, whether it be not
probable that our Ideas do, whilst we are awake, succeed one
another in our Minds at certain distances, not much unlike the
Images in the inside of a Lanthorn, turned round by the Heat of a
Candle. This Appearance of theirs in train, though, perhaps, it may
be sometimes faster, and sometimes slower; yet, I guess, varies not
very much in a waking Man: There seem to be certain Bounds to the
quickness and slowness of the Succession of those Ideas one to another in
our Minds, beyond which they can neither delay nor hasten.
Locke Hum II, 14, §9, p. 184
