Thus the series of spaces in the parallel moments of one temporal series may have their own definition of absolute position correlating sets of event-particles in these successive spaces, so that each set consists of event-particles, one from each space, all with the property of possessing the same absolute position in that series of spaces.

Such a set of event-particles will form a point in the timeless space of that time-system.

Thus a point is really an absolute position in the timeless space of a given time-system.
But there are alternative time-systems, and each time-system has its own peculiar group of points--that is to say, its own peculiar definition of absolute position.

This is exactly the theory which I will elaborate.
In looking to nature for evidence of absolute position it is of no use to recur to the four-dimensional manifold of event-particles.

This manifold has been obtained by the extension of thought beyond the immediacy of observation.
