In the case of the Great Pyramid, the object is the perceived unit entity which as perceived remains self-identical throughout the ages; while the whole dance of molecules and the shifting play of the electromagnetic field are ingredients of the event.

An object is in a sense out of time.

It is only derivatively in time by reason of its having the relation to events which I term 'situation.' This relation of situation will require discussion in a subsequent lecture.
The point which I want to make now is that being the situation of a well-marked object is not an inherent necessity for an event.

Wherever and whenever something is going on, there is an event.

Furthermore 'wherever and whenever' in themselves presuppose an event, for space and time in themselves are abstractions from events.
