It is this character of being an absolute minimum which we want to get at and to express in terms of the extrinsic characters of the abstractive sets which make up a point.

Furthermore, points which are thus arrived at represent the ideal of events without any extension, though there are in fact no such entities as these ideal events.

These points will not be the points of an external timeless space but of instantaneous spaces.

We ultimately want to arrive at the timeless space of physical science, and also of common thought which is now tinged with the concepts of science.

It will be convenient to reserve the term 'point' for these spaces when we get to them.
