book. There is not only a significance of the
discerned events embracing the whole present duration, but there is a
significance of a cogredient event involving its extension through a
whole time-system backwards and forwards. In other words the essential
'beyond' in nature is a definite beyond in time as well as in space [cf.
pp. 53, 194]. This follows from my whole thesis as to the assimilation
of time and space and their origin in extension. It also has the same
basis in the analysis of the character of our knowledge of nature. It
follows from this admission that it is possible to define point-tracks
[_i.e._ the points of timeless spaces] as abstractive elements. This is
a great improvement as restoring the balance between moments and points.
I still hold however to the statement in subarticle 35.4 of the
_Principles_ that the intersection of a pair of non-parallel durations
does not present itself to us as one event. This correction does not
affect any of the subsequent reasoning in the two books.

I may take this opportunity of pointing out that the 'stationary events'
of article 57 of the _Principles_ are merely cogredient events got at
from an abstract mathematical point of view.
