CHAPTER IV.
THE METHOD OF EXTENSIVE ABSTRACTION To-day's lecture must commence with the consideration of limited events.
We shall then be in a position to enter upon an investigation of the factors in nature which are represented by our conception of space.
The duration which is the immediate disclosure of our sense-awareness is discriminated into parts.

There is the part which is the life of all nature within a room, and there is the part which is the life of all nature within a table in the room.

These parts are limited events.

They have the endurance of the present duration, and they are parts of it.
But whereas a duration is an unlimited whole and in a certain limited sense is all that there is, a limited event possesses a completely defined limitation of extent which is expressed for us in spatio-temporal terms.
We are accustomed to associate an event with a certain melodramatic quality.

If a man is run over, that is an event comprised within certain spatio-temporal limits.
