A discerned event is known as related in this structure to other events whose specific characters are otherwise not disclosed in that immediate awareness except so far as that they are relata within the structure.
The disclosure in sense-awareness of the structure of events classifies events into those which are discerned in respect to some further individual character and those which are not otherwise disclosed except as elements of the structure.

These signified events must include events in the remote past as well as events in the future.

We are aware of these as the far off periods of unbounded time.

But there is another classification of events which is also inherent in sense-awareness.
These are the events which share the immediacy of the immediately present discerned events.

These are the events whose characters together with those of the discerned events comprise all nature present for discernment.
