We are not accustomed to consider the endurance of the Great Pyramid throughout any definite day as an event.

But the natural fact which is the Great Pyramid throughout a day, meaning thereby all nature within it, is an event of the same character as the man's accident, meaning thereby all nature with spatio-temporal limitations so as to include the man and the motor during the period when they were in contact.
We are accustomed to analyse these events into three factors, time, space, and material.

In fact, we at once apply to them the concepts of the materialistic theory of nature.

I do not deny the utility of this analysis for the purpose of expressing important laws of nature.

What I am denying is that anyone of these factors is posited for us in sense-awareness in concrete independence.
