We cannot redouble our efforts to improve our knowledge of the terminus of our present sense-awareness; it is our subsequent opportunity in subsequent sense-awareness which gains the benefit of our good resolution.

Thus the ultimate fact for sense-awareness is an event.

This whole event is discriminated by us into partial events.

We are aware of an event which is our bodily life, of an event which is the course of nature within this room, and of a vaguely perceived aggregate of other partial events.

This is the discrimination in sense-awareness of fact into parts.
I shall use the term 'part' in the arbitrarily limited sense of an event which is part of the whole fact disclosed in awareness.
Sense-awareness also yields to us other factors in nature which are not events.
