The difficulty is to express our meaning in terms of the immediate deliverances of sense-awareness, and I offer the above explanation as a complete solution of the problem.
In this explanation a moment is the set of natural properties reached by a route of approximation.

An abstractive series is a route of approximation.

There are different routes of approximation to the same limiting set of the properties of nature.

In other words there are different abstractive sets which are to be regarded as routes of approximation to the same moment.

Accordingly there is a certain amount of technical detail necessary in explaining the relations of such abstractive sets with the same convergence and in guarding against possible exceptional cases.
